PLANNING AND HOUSING COMMISSION STAFF REPORT
DATE: 01/23/2023
TO: Honorable Chair and Commissioners
FROM: Planning & Development Department
APPLICATION REQUEST:

GPA2022-0002: General Plan land use amendment on various properties to allow certain residential land uses consistent with the General Plan Housing Element sites inventory and commensurate text changes to certain land use designations in the General Plan.

RECOMMENDED ACTION:

That the Planning and Housing Commission recommend to the City Council the adoption of the Supplemental Environmental Impact Report for the Corona Housing Element Rezoning Program and APPROVAL of GPA2022-0002, based on the findings contained in the staff report, and adopt Resolution No. 2603 granting GPA2022-0002 as part of Cycle 1 of General Plan Amendments for 2023.

BACKGROUND
The City Council adopted the General Plan Housing Element 2021-2029 on November 3, 2021. The Housing Element is a state mandated document that is required to be updated every eight years. On October 12, 2022, the California Department of Housing and Community Development approved the City’s Housing Element and found the document to be in compliance with State Housing Element Law (Government Code Article 10.6). The Housing Element requires the City to rezone and amend the General Plan land use of certain properties to meet its state mandated regional housing need.

The Housing Element 2021-2029 aligns with the State’s allocation of the Regional Housing Needs Assessment, commonly known as RHNA. The Southern California Association of Governments (SCAG) Regional Council adopted the final RHNA allocation for the jurisdictions within its region at its meeting on March 4, 2021. The City of Corona was issued a final RHNA allocation of 6,088 housing units. The City is required to demonstrate the planning of these units based on each income category within the Housing Element for the next eight years. Corona’s RHNA allocation based on income categories is shown in the below table.

The City’s availability of vacant, undeveloped properties has decreased over the years due to development. It is also especially challenging to find properties suitable for higher density residential, which is crucial in planning enough sites to accommodate low- and moderate-income housing units. Sites suitable for low-income units must have a zoning and General Plan designation that allows a higher density of at least 30 dwelling units to the acre. Moderate income units also can be accounted for in the higher density but can be included in a medium density that allows up to 15 dwelling units to the acre.

Housing Program 7 of the Housing Element requires the City’s to identify adequate housing sites that could be developed with housing according to the income categories required by the City’s RHNA allocation. The City does have a lack of sites available for high density residential, which creates a shortfall in having enough sites available for the planning of low- and moderate-income units.

Housing Program 7 requires the City to rezone certain properties so that enough sites are available for the potential development of high density residential that would support the planning of low- and moderate-income units.

General Plan Amendment 2022-0002 (GPA2022-0002) is part of the rezoning program described by Housing Program 7 of the Housing Element. The General Plan amendment will: a) change the land use designation on certain properties identified on the Housing Element Sites Inventory to allow high -density residential or medium density residential that would otherwise not be allowed or only allowed if constructed as part of a commercial and residential mixed-use development, and b) amend the land use description and density of the Urban Density Residential, Mixed Use I Commercial and Residential, and Mixed Use II Industrial and Commercial General Plan designations to allow higher density residential development.

In addition to GPA2022-0002, Change of Zone 2022-0003 (CZ2022-0003), Specific Plan Amendment 2022-0003 (SPA2022-0003), and Community Facilities Plan Amendment 2022-0002 (CFPA2022-0002) are being processed as part of the rezoning program to accommodate the land use changes that are being made to certain properties on the City’s Housing Sites Inventory. Additionally, a Zone Text Amendment (ZTA2022-0002) to Title 17 of the Corona Municipal Code (CMC) is being processed to establish regulations for an Affordable Housing Overlay Zone. The regulations for the AHO zone are City of Corona Page 2 of 9 Printed on 1/18/2023

File #: 23-0082
establish regulations for an Affordable Housing Overlay Zone. The regulations for the AHO zone are being added as Chapter 17.31 of the CMC. Properties identified with an Affordable Housing Overlay (AHO) zone will be allowed to develop high density residential if 20% of the total housing units within a project are set aside for low income housing. Finally, the consideration of High Density Residential and Mixed-Use Objective Development Standards and Design Guidelines are also proposed, which would apply to properties being developed pursuant to the requirements of the AHO zone. The objective development standards and design guidelines covers required building setbacks, building height, lot coverage, on-site passive and active open space, site design, and building design standards.

PROJECT DESCRIPTION
The Housing Element Rezoning Program covers various properties located in the City. Due to the number of properties and the locations, the City grouped and separated the properties into 11 Zones so that the areas can be easily identified. Exhibits 3 through 12 show the location of each zone area affected by GPA2022-0002. The following table summarizes the general location of the properties within each zone.

Zones 1, 2 and 5 represent the City’s historic commercial corridors on West and East 6th Street and North Main Street. Over the years, properties within the North Main Street corridor have been redeveloped to replace aging and declining shopping centers with new commercial uses and high density residential. Like North Main Street, aging commercial properties that exist along the West and East 6th Street commercial corridor have the potential to be redeveloped to include high density residential or commercial and residential mixed-use. These sites were considered as part of the rezoning program for higher density residential because of the existing urban environment and proximity to regional public transportation. The City also has seen changes in the retail market, which includes a decline in retail storefronts due to the competition from online retail sales.

Therefore, the rezoning of these sites lend opportunity for these sites to be redeveloped with housing that can further support the planning of low- and moderate-income units and allow the City to meet its state mandated housing requirement.

Proposed General Plan Amendment
Land Use Amendment
GPA2022-0002 amends the land use designation of certain properties located in Zone 1 through 9 and Zone 11 Areas. In certain cases, the designation of the property is being amended to:
a) allow Mixed Use I commercial and residential development, where mixed-use may not currently be allowed,
b) change the land use designation from General Commercial to High Density Residential (15-36 du/ac),
c) change the land use designation from High Density Residential (15-36 du/ac) to Urban Density Residential (36-60 du/ac),
d) change the land use designation from Low Density Residential (3-6 du/ac) to Medium Density Residential (6-15 du/ac), and
e) change the land use designation from Light Industry to Mixed Use II commercial and industrial development.

The properties associated with GPA2022-0002 are identified in Exhibits 3 through 12 attached to this staff report. These exhibits include a map showing the location of the properties and a table identifying each property and the proposed change in land use. Most of the properties are being amended to the Mixed-Use I designation to allow high density, multiple family residential. These City of Corona Page 4 of 9 Printed on 1/18/2023
powered by Legistar™
File #: 23-0082
amended to the Mixed-Use I designation to allow high density, multiple family residential. These properties satisfy the City’s requirement of providing enough sites that would be allowed low and moderate-income housing units.

In addition to the higher density designations being proposed, other sites in the city also have been identified to be changed from Low Density Residential to Medium Density Residential. These sites were seen as having the potential for providing moderate-income housing units. The sizes of the properties provide an opportunity for additional housing units to be constructed on sites that already have one single family dwelling. The opportunity on some of these sites is discussed below, while other sites have been identified in Exhibits 4, 6, 7, 9 and 12.

Zone 8 Area
The properties in this area are located east of Fullerton Avenue on Ford Street and Barth Street (Exhibit 10). The properties are long rectangular lots that are approximately a half-acre. The properties are designated Low Density Residential on the General Plan and zoned R-1-7.2 (Single Family Residential). The properties contain a one-single family dwelling with some backyard space improved. However, the remaining areas of the properties are unused. Based on the size of these sites and the current development, these sites have the potential to support additional housing units.

GPA2022-0002 would amend the General Plan of these properties from Low Density (3-6 du/ac) to Medium Density Residential (6-15 du/ac). At the same time, the zoning is also being changed from R-1-7.2, a single-family residential zone, to R-2, a low-density, multiple family residential zone by change of zone application CZ2022-0003.

Zone 9 and 11 Areas
The Department was contacted by Evangelical Friends Church located at 1220 W. Ontario Avenue (Zone 9 Area) and United Methodist Church of Corona located at 2880 California Avenue (Zone 11 Area) during the Housing Element process (Exhibits 11 and 12). Both congregations expressed interest in providing housing on the respective properties. Evangelical Friends Church is interested in providing housing for families that may not be able to afford market rate units and United Methodist Church is interested in providing housing for senior citizens. Both churches are small congregations and do not foresee the expansion of their existing congregations on the excess unused land.

The properties are being amended from Low Density Residential, 3 to 6 dwelling units per acre to Medium Density Residential, 6 to 15 dwelling units per acre. The Evangelical Friends Church located at 1220 W. Ontario Avenue is adjacent to another congregation to the west, a Southern California Edison Transformer Station to the east and single-family residences to the south. The United Methodist Church of Corona located at 2880 California Avenue is adjacent to a city park site to the west, a congregation to the north, and is across the street from Santiago High School and singlefamily residences to the south and east.

Text Amendment to General Plan Land Use Designations Table LU-1 The rezoning program described in Housing Element Program 7 requires the City to amend the General Plan Mixed Use I (MU I) and Mixed Use II (MU II) designations to allow 100% residential uses on sites zoned with an Affordable Housing Overlay. This provides more opportunity for affordable housing to be considered for development by not limiting residential development to a mixed-use development. The amendment will add language to the MU I and MU II descriptions to City of Corona Page 5 of 9 Printed on 1/18/2023
powered by Legistar™
File #: 23-0082
mixed-use development. The amendment will add language to the MU I and MU II descriptions to include:

Accommodates 100% residential use if affordable housing is provided pursuant to the requirements of the Affordable Housing Overlay (AHO) Zone.

Density for 100% residential use: 45-60 du/adjusted gross acre.

The above language provides flexibility that will allow properties that are not zoned with an AHO to provide affordable housing if the affordable housing meets the requirements of the AHO zone. This is being done in response to the passage of Senate Bill 6, which makes residential development an allowable use on properties that are zoned to allow office, retail and parking on parcels 20 acres or less. For example, if a property has a General Plan MU 1 designation and zoned Commercial but not with an AHO zone, and the owner proposes to build affordable housing units on the property, the property would be allowed to exercise the requirements of the AHO zone and be allowed a 100% residential use. Properties not zoned with an AHO with a MU General Plan designation and developed with no affordable housing component will fall under the original General Plan description for mixed use, which allows residential only if a commercial component is included in the MU I designation and residential as prohibited in the MU II designation.

The Urban Density Residential (UDR) designation accommodates residential development within a density range of 36-60 du/adj. gross acre. This amendment will add the following language to the UDR designation:

Density with an Affordable Housing Overlay Zone: 45-60 du/adj. gross acre.

The amendment increases the lowest end of the density range from 36 to 45 du/ac. The AHO zone is intended to promote higher density residential so that affordable housing units can be accommodated in a residential development that may also include market rate units. Additionally, the residential density range would be consistent with the density range proposed in the MU I and MU II designations if the development proposes affordable housing units.

ENVIRONMENTAL ANALYSIS
The City prepared a Supplemental Environmental Impact Report (EIR) for the Corona Housing Element Rezoning Program in accordance with the California Environmental Quality Act (CEQA) to evaluate potential environmental impacts associated with the implementation of the City of Corona General Plan Housing Element Rezoning Program Update Project. This document is prepared in conformance with CEQA (California PRC Section 21000, et seq.) and the CEQA Guidelines (California Code of Regulations [CCR], Title 14, Section 15000, et seq.). The Supplemental EIR adequately addresses impacts from minor changes to the Corona General Plan Technical Update 2020 Final EIR certified on June 3, 2020, by the City Council. As required by CEQA, the Supplemental EIR only contains information necessary to analyze the project modifications, changed circumstances, or new information that triggered the need for additional environmental review. The Supplemental EIR only contains the information necessary to make the previous EIR adequate for the project as revised.

The Supplemental EIR indicated that the Housing Element Rezoning Program will not result in City of Corona Page 6 of 9 Printed on 1/18/2023

impacts not already identified in the Corona General Plan Technical Update 2020 Final EIR.

FISCAL IMPACT
GPA2022-0002 is a city-initiated application. No application fee was paid to process this request.

PUBLIC NOTICE AND COMMENTS
A 20 day public notice was mailed to all property owners within a 500-foot radius of the project site, as well as advertised in the Sentinel Weekly News. As of the preparation of this report, staff has received several emails and phone calls from property owners near sites being rezoned or from owners that have property being rezoned. Most of the calls required further clarification on the permitted land uses under the rezoning program and if the existing land uses on the properties affected by the rezoning are allowed to be continued. Staff confirmed that existing land uses are allowed to remain on the property and that the rezoning program is an opportunity for redevelopment to allow housing should the owner decide to exercise that option in the future.

Email correspondence submitted by the public is included in Exhibit 14.

STAFF ANALYSIS
Residential land use designations within the General Plan are tied to a density range; meaning residential uses can be developed in the respective residential land use designation and to a density that falls within the density range prescribed by the General Plan. For conservative purposes, the General Plan Amendment considers the potential number of allowed residential units based on the maximum density allowed within the density range. GPA2022-0002 would allow approximately 5,400 residential units by using the maximum density of 60 du/ac for the MU I and MU II designations and in other areas 36 du/ac with the High Density Residential designation. It is worth mentioning that the MU I designation already allowed a residential component when developed with commercial as a mixed- use development. However, a mixed-use development would use a Floor Area Ratio to determine the maximum area to be developed instead of dwelling units to the acre.

The Housing Element Rezoning Program is a planning requirement to make a path for the development of housing units in accordance with the City’s mandated regional housing need. It does not guarantee that housing will be developed on all the properties identified in the housing sites inventory. Future development on these properties and in most cases the redevelopment of these properties will be determined by market conditions. At the same time however, the city needs to maintain land that can support the development of residential units based on the regional housing need during the eight- year period of the current Housing Element. GPA2022-0002 gives the city a buffer to account for possible shortfall in housing sites.

FINDINGS FOR THE APPROVAL OF GPA2022-0002

1. The City prepared a Supplemental Environmental Impact Report (EIR) for the Corona Housing Element Rezoning Program in accordance with the California Environmental Quality Act (CEQA) to evaluate potential environmental impacts associated with the implementation of the City of Corona General Plan Housing Element Rezoning Program Update Project. This document is prepared in conformance with CEQA (California PRC Section 21000, et seq.) and the CEQA Guidelines (California Code of Regulations [CCR], Title 14, Section 15000, et seq.).

the CEQA Guidelines (California Code of Regulations [CCR], Title 14, Section 15000, et seq.).

The Supplemental EIR adequately addresses impacts from minor changes to the Corona General Plan Technical Update 2020 Final EIR certified on June 3, 2020, by the City Council.

As required by CEQA, the Supplemental EIR only contains information necessary to analyze the project modifications, changed circumstances, or new information that triggered the need for additional environmental review. The Supplemental EIR only contains the information necessary to make the previous EIR adequate for the project as revised. The Supplemental EIR indicated that the Housing Element Rezoning Program will not result in impacts not already identified in the Corona General Plan Technical Update 2020 Final EIR.

2. GPA2022-0002 is in the public interest and would not be detrimental to public health, safety and welfare for the following reasons:
a. GPA2022-0002 plans for higher density residential development within the City’s High Quality Transit Area, which is intended and suited for transit- oriented development that supports urban density residential development within proximity to general commercial services and medical services.
b. GPA2022-0002 considers the land uses of the surrounding properties and proposes land uses that are consistent with the surrounding environment to avoid land use incompatibilities associated with development.

3. GPA2022-0002 is internally consistent with the elements of the General Plan, including the goals and policies stated therein for the following reasons:
a. GPA2022-0002 is consistent with Goal H-1 because it establishes land use designations on certain properties that help promote a balance of housing types for corresponding affordability levels that assist in meeting the demand for housing within all economic segments of the City.
b. GPA2022-0002 is consistent with Policy H-1.3 because it provides sites for residential development, including sites for affordable housing so that the scarcity of land does not unduly increase the cost or decrease the availability of housing for all economic segments of the community.

EXECUTIVE SUMMARY
ES.1 PURPOSE
This Draft Supplemental Environmental Impact Report (SEIR) to the Corona General Plan Technical Update 2020 Final Environmental Impact Report (FEIR) is prepared in accordance with the California Environmental Quality Act (CEQA) (California Public Resources Code (PRC), Section 21000, et seq.) and the CEQA Guidelines (California Code of Regulations [CCR], Title 14, Section 15000, et seq.) to evaluate the potential environmental impacts associated with the proposed City of Corona General Plan Housing Element Rezoning Program Update Project (Project). The purpose of this Draft SEIR is to inform decision makers, representatives of affected and responsible agencies, the public, and other interested parties of the potential environmental effects that may result from implementation of the proposed Project. This Draft SEIR describes potential impacts relating to a wide variety of environmental issues and the methods by which these impacts may be mitigated or avoided.

ES.2 PROJECT LOCATION
The Project is located in the City of Corona (Corona), which is in northwestern Riverside County (County).

ES.3 PROJECT SUMMARY
In accordance with California Government Code Section 65584, projected housing needs for each city and county in the Southern California region are prepared by Southern California Association of Governments (SCAG) under a process known as the Regional Housing Needs Assessment (RHNA). The RHNA allocates regional housing needs by income level among member jurisdictions. California law established the planning period for the current RHNA from June 30, 2021, to October 15, 2029.

Implementation of the Project is intended to accommodate the planning of low- and moderate-income households in the City, in accordance with the City’s recently adopted 2021-2029 Housing Element Update.

In addition to including goals, policies, and implementation programs regarding housing issues, housing elements must include an inventory or list of housing sites at sufficient densities to accommodate a specific number of units at various levels of affordability assigned to the City by SCAG. The Housing Element Update includes an inventory of properties that are intended to be rezoned to high density residential or an Affordable Housing Overlay (AHO) zone in order to plan for low- and moderate-income units. The AHO zone is a new zoning designation that the City proposes to establish in order to create by-right development standards for affordable housing projects. The City also proposes to create development standards and architectural design guidelines for the AHO zone, which would cover existing properties that are developed City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Executive Summary
ES-2
with non-residential uses. The AHO zone would allow these properties to be redeveloped with residential land uses should a percentage of the housing units include low- and moderate-income housing.

ES.4 AREA OF CONTROVERSY/ISSUES TO BE RESOLVED
Section 15123 of the CEQA Guidelines requires that a summary of an Environmental Impact Report (EIR) identify areas of controversy known to the lead agency, including issues raised by agencies and the public.

On July 1, 2022, the City issued a Notice of Preparation (NOP) and Initial Study (IS) (Appendix A) to inform agencies and the general public that a SEIR was being prepared. The NOP was circulated between July 1, 2022, and August 1, 2022, for the statutory 30-day public review period. The City invited comments on the scope and content of the document, and participation at a public scoping meeting on July 20, 2022, at Corona City Hall Multi-Purpose Room. Appendix A of this Draft SEIR contains a scoping report listing the written comments received on the NOP and during the public scoping meeting. During the public comment period for the NOP, four comment letters were received regarding the proposed Project’s Initial Study and none were received during the public scoping meeting. In general, areas of potential controversy known to the City include:
• Impacts related to air quality and greenhouse gas emissions • Impacts related to the use of energy and resources
• Impacts to land use and planning
• Impacts to parks and recreation resources
• Impacts related to noise and vibration
• Impacts related to transportation and traffic
• Impacts related to tribal cultural resources
Table ES-1, Executive Summary of Impacts and Mitigation Measures, summarizes the detailed discussion contained in Section 3.0, Environmental Setting, Impacts and Mitigation, of this Draft SEIR.

ES.5 DISAGREEMENT AMONG EXPERTS
This Draft SEIR contains substantial evidence to support the conclusions presented herein. It is possible that there will be disagreement among various parties regarding these conclusions, although the City is not aware of any disputed conclusions at the time of this writing. Both the CEQA Guidelines and case law clearly provide the standards for treating disagreement among experts. Where evidence and opinions conflict on an issue concerning the environment, and the lead agency knows of these controversies in advance, the EIR must acknowledge the controversies, summarize the conflicting opinions of the experts, and include sufficient information to allow the public and decision-makers to make an informed judgment about the environmental consequences of the proposed Project.

City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Executive Summary
ES-3
ES.6 SIGNIFICANT UNAVOIDABLE IMPACTS
Project implementation would result in the following significant unavoidable adverse impacts:
• Air Quality: The proposed Project would conflict with or obstruct implementation of the applicable AQMP; would result in a cumulatively considerable net increase of VOCs, NOx, PM10, and PM2.5 for which the project region is non-attainment under applicable federal or State ambient air quality standard; and would contribute to elevated levels of TACs in the air basin. Additionally, the Project would result in a cumulatively considerable contribution to a significant cumulative air quality impact. Therefore, impacts related to air quality would remain significant and unavoidable as noted in the General Plan EIR.
• Greenhouse Gas Emissions: Implementation of the proposed Project may not meet the long-term greenhouse gas reduction goal under Executive Order S-03-05 and would also result in a cumulatively considerable contribution to a significant cumulative greenhouse gas emission impact.

Therefore, impacts related to greenhouse gas emissions would remain significant and unavoidable as noted in the General Plan EIR.
• Noise: Implementation of the proposed Project would result in impacts with respect to temporary construction noise and impacts would remain significant and unavoidable as noted in the General Plan EIR.
• Transportation: Implementation of the proposed Project would result in increase in VMT from existing conditions and would also result in a cumulative considerable contribution to a significant transportation impact, and therefore, impacts would remain significant and unavoidable as noted in the General Plan EIR.

ES.7 SUMMARY OF PROJECT ALTERNATIVES
An EIR must describe a range of reasonable alternatives to the project or alternative project locations that could feasibly attain most of the basic project objectives and would avoid or substantially lessen any of the significant environmental impacts of the proposed project. The alternative analysis must include the “No Project Alternative” as a point of comparison. The No Project Alternative includes existing conditions and reasonably foreseeable future conditions that would exist if the proposed Project were not approved (CEQA Guidelines Section 15126.6). The following alternatives are discussed further in Section 7.0, Alternatives, of this document.

Alternative 1 – No Project
CEQA Guidelines Section 15126.6(e)(1) requires that the no project alternative be described and analyzed, “to allow decision-makers to compare the impacts of approving the project with the impacts of not approving the project.” The no project analysis is required to discuss, “the existing conditions at the time the Notice of Preparation is published… as well as what would be reasonably expected to occur in the foreseeable future if the project were not approved, based on current plans and consistent with available infrastructure and community services” (Section 15126.6(e)(2)).

City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Executive Summary
ES-4
The No Project Alternative assumed that no rezoning program would take place and the identified Project sites would continue to be designated as identified in the General Plan Update without any increase in residential density. The No Project Alternative would maintain the status quo of the General Plan Update and would not accommodate the City’s state mandated RHNA allocation in accordance with the Housing Element for Planning Period 2021-2029. The No Project Alternative would not achieve any of the project objectives to provide adequate housing sites for all income levels within the City, promote housing opportunities that support the City’s state mandated RHNA, promote fair housing opportunities that encourage access to lower- and moderate-income housing, and promote safe and healthy housing opportunities to discourage overcrowding.

Alternative 2 – Reduced Density Alternative Up To 45 Dwelling Units per Acre The Project proposes to apply an AHO zone at a maximum density of 60 dwelling units per acre to 100 identified sites to accommodate 4,651 additional housing units. The Reduced Density Alternative would reduce the maximum density on the AHO zone parcels to 45 dwelling units per acre. The Reduced Density Alternative would reduce the number of residential units the AHO zone could accommodate to 3,492 dwelling units.

Vacant parcels (750 units) and nonvacant parcels (452 units) can accommodate a total of approximately 1,202 new housing units, and potential rezone parcels (368 units) and AHO parcels (3,492 units) at a maximum density of 45 units per acre can accommodate a total of approximately 5,062 additional housing units. Based on this, by implementing the Reduced Density Alternatives, the City would be able to accommodate the 2021-2029 RHNA and provide a RHNA-buffer of 4 percent for low-income households and a 1.5 percent buffer for moderate-income households.

Alternative 3 – Alternate Development Areas
Alternative 3 is consideration of different locations for redevelopment. A Citywide comprehensive land survey has been conducted, and the candidate sites have been selected in order to support the City’s objectives to sustainably increase residential density, especially in a transit-oriented community.

Consideration of alternative locations may take place in areas that are not well-suited for the intensified residential redevelopment or within a transit-oriented community. Development standards within transitoriented communities aim to support the highest density for the proposed Project, as they are intended to encourage compact development, improve access to transit, and promote a pedestrian-oriented environment. Transit-oriented community development standards would require a minimum of 60 units per acre, as provided by the proposed Project.

ES.8 SUMMARY OF IMPACTS AND MITIGATION MEASURES
This Draft SEIR analyzes the potential environmental effect of the Project. The Initial Study (Appendix A) prepared for the Project determined that the following topics would have either no significant impact or impacts that would be reduced to less than significant with incorporation of mitigation measures identified in the City’s General Plan EIR.

The Initial Study identified impacts related to air quality, energy, greenhouse gas emission, land use and planning, noise, public services (parks), recreation, transportation and tribal cultural resources requiring a more detailed evaluation, which is discussed in Section 3.0, Environmental Setting, Impact, and Mitigation, of this Draft SEIR.

Table ES-1, Summary of Impacts and Mitigation Measures from the Initial Study, summarizes the potential environmental effects of the proposed Project and the mitigation measures from the Initial Study. Table ES2, Summary of Impacts and Mitigation Measures from the SEIR, has been organized to correspond with environmental issues discussed in Section 3.0, Environmental Setting, Impacts and Mitigation, of this SEIR.

Table ES-1 and ES-2 are arranged in four columns: 1) impacts; 2) level of significance without mitigation; 3) mitigation measures; and 4) level of significance with mitigation.

Pursuant to CEQA Guidelines Section 15093, if the proposed Project is approved as proposed, any impact noted in the summary as “significant” after mitigation would require the adoption of overriding considerations. As shown in Table ES-2, development of the proposed Project with mitigation measures would result in significant and unavoidable impacts to air quality, greenhouse gas emissions, noise and transportation. Therefore, a statement of overriding considerations would be required during certification of the Final SEIR.

Additionally, CEQA requires public agencies to establish a monitoring and reporting program for the purpose of ensuring compliance with those mitigation measures adopted as conditions of approval in order to mitigate or avoid significant environmental impacts identified in an EIR. A Mitigation Monitoring and Reporting Program, incorporating the mitigation measures set forth in this document, would be adopted at the time of certification of the Final SEIR.

Mitigation Measure BIO-1. Applicants for future
development projects shall include a biological resources survey if it has been determined that the site in its existing condition may contain biological habitat or species. The biological resources survey shall be conducted by a
qualified biologist. The biological resources survey shall include, but not be limited to:

An analysis of available literature and biological databases, such as the California Natural Diversity Database, to
determine sensitive biological resources that have been reported historically from the proposed development project vicinity.

A review of current land use and land ownership within the proposed development project vicinity.

An assessment and mapping of vegetation communities
present within the proposed development project vicinity.

An evaluation of potential local and regional wildlife
movement corridors.

A general assessment of potential jurisdictional areas, including wetlands and riparian habitats.

Habitat Assessment. If the proposed development project site supports vegetation communities that may provide
habitat for plant or wildlife species, a focused habitat assessment shall be conducted by a qualified biologist to determine the potential for special status plant and/or animal species to occur within or adjacent to the proposed development project area. Adjoining properties should also be surveyed where direct or indirect project effects, such as those from fuel modification or herbicide application, could potentially extend off-site. If feasible, the habitat
assessment should be conducted during non-drought years.

Focused Surveys. If one or more special status species has the potential to occur within the proposed development
project area, focused species surveys shall be conducted to determine the presence/absence of these species to
adequately evaluate potential direct and/or indirect impacts to these species. The focused survey shall record the
location and boundary of special status species by use of global positioning system (GPS). The number of individuals in each special status plant population shall be provided as counted (if population is small) or estimated (if population is large). If applicable, information about the percentage of individuals in each life stage, such as seedlings vs.
reproductive individuals, should be provided. If feasible, images of the target species and representative habitats should be included to support information and descriptions.

Preconstruction Surveys. If construction activities are not initiated immediately after focused surveys have been
completed, additional preconstruction special status species surveys may be required to ensure impacts are avoided or minimized to the extent feasible. If preconstruction activities are required, a qualified biologist would perform these surveys as required for each special status species that is known to occur or has a potential to occur within or adjacent to the proposed development project area.

Biological Resources Report. The results of the biological survey for proposed development projects with no
significant impacts may be presented in a biological survey letter report. For proposed development projects with
significant impacts that require mitigation to reduce the impacts to below a level of significance, the results of the biological survey shall be presented in a biological technical report.

Mitigation Measure BIO-2. If sensitive biological resources are identified within or adjacent to the proposed
development project area, the construction limits shall be clearly flagged to ensure impacts to sensitive biological resources are avoided or minimized to the extent feasible.

Prior to implementing construction activities, a qualified biologist shall verify that the flagging clearly delineates the construction limits and sensitive resources to be avoided.

educate project contractors on the sensitive biological resources within and adjacent to the proposed development project area and measures being implemented to avoid
and/or minimize impacts to these species. A qualified
biologist shall develop and implement the contractor training program.

Mitigation Measure BIO-4. If sensitive biological resources are present within or adjacent to the proposed development project area and impacts may occur from implementation of construction activities, a qualified biological monitor may be required during a portion or all of the construction activities to ensure impacts to the sensitive biological resources are avoided or minimized to the extent feasible. The specific biological monitoring requirements shall be evaluated on a project-by-project basis. The qualified biological monitor shall be approved by the City on a project-by-project basis based on applicable experience with the sensitive biological resources that may be impacted.

Mitigation Measure BIO-7. The City of Corona shall require applicants for future development projects to contract with a qualified biologist to conduct a preconstruction general nesting bird survey within all suitable nesting habitats that may be impacted by active construction during general
avian breeding season (February 1 through August 31). The preconstruction surveys shall be conducted no more than 7 days prior to initiation of construction. If no active avian nests are identified within the proposed development project area or within a 300-foot buffer of the proposed
development project area, no further mitigation is
necessary. If active nests of avian species covered by the Fish and Game Code are detected within the proposed
development project area or within a 300-foot buffer of the proposed development project area, construction shall be halted until the young have fledged, until a qualified biologist has determined the nest is inactive, or until appropriate mitigation measures that respond to the specific situation have been developed and implemented in consultation with the regulatory agencies.

Mitigation Measure CUL-2. To ensure that projects
requiring the relocation, rehabilitation, or alteration of a historical resource not impair its significance, the Secretary of the Interior’s Standards for the Treatments of Historic Properties shall be used to the maximum extent possible.

The application of the standards shall be overseen by a qualified architectural historian or historic architect meeting the PQS. Prior to any construction activities that may affect the historical resource, a report identifying and specifying the treatment of character-defining features and construction activities shall be provided to the City of Corona.

Mitigation Measure CUL-3. If a proposed project would
result in the demolition or significant alteration of a historical resource, it cannot be mitigated to a less than significant level. However, recordation of the resource prior to
construction activities will assist in reducing adverse impacts to the resource to the greatest extent possible. Recordation shall take the form of Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), or Historic American Landscape Survey (HALS)
documentation, and shall be performed by an architectural historian or historian who meets the PQS. Documentation shall include an architectural and historical narrative; medium- or large-format black and white photographs,
negatives, and prints; and supplementary information such City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

In the event that archaeological resources (artifacts or features) are exposed during ground disturbing activities, construction activities in the immediate vicinity of the discovery shall be halted while the on-call archaeologist is contacted. If the discovery proves to be significant, it shall be curated with a recognized scientific or educational repository.

Mitigation Measure TCR-1. Tribal Cultural Resources Monitoring.

The project archaeologist, in consultation with interested tribes, the developer and the City of Corona, shall develop an Archaeological Monitoring Plan (AMP) to address the details, timing and responsibility of archaeological and cultural activities that will occur on the project site. Details in the AMP shall include:

1. Project-related ground disturbance (including, but not limited to, brush clearing, grading, trenching, etc.) and development scheduling;

2. The development of a rotating or simultaneous schedule in coordination with the developer and the project archeologist for designated Native American Tribal Monitors from the consulting tribes during grading, excavation and ground disturbing activities on the site: including the scheduling, safety requirements, duties, scope of work, and Native American Tribal Monitors’ authority to stop and redirect grading activities in coordination with all project archaeologists (if the tribes cannot come to an agreement on the rotating or simultaneous schedule of tribal monitoring, the Native American Heritage Commission City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Executive Summary
ES-21
shall designate the schedule for the onsite Native American Tribal Monitor for the proposed project);

3. The protocols and stipulations that the developer, City, Tribes and project archaeologist will follow in the event of inadvertent cultural resources discoveries, including any newly discovered cultural resource deposits that shall be subject to a cultural resources evaluation.

At least 30-days prior to application for a grading permit and before any brush clearance, grading, excavation and/or ground disturbing activities on the site take place, the future developer shall retain a tribal cultural monitor to monitor all ground-disturbing activities in an effort to identify any unknown archaeological resources.

Mitigation Measure TCR-2. Treatment and Disposition of Cultural Resources. In the event that Native American cultural resources are inadvertently discovered during the course of any ground disturbing activities, including but not limited to brush clearance, grading, trenching, etc. grading for the proposed project, the following procedures will be carried out for treatment and disposition of the discoveries:

1. Temporary Curation and Storage: During the course of construction, all discovered resources shall be temporarily curated in a secure location onsite or at the offices of the project archaeologist. The removal of any artifacts from the project site will need to be thoroughly inventoried with tribal monitor oversite of the process; and

Reburial shall not occur until all cataloguing, basic analysis, and other analyses as recommended by the project
archaeologist and approved by consulting tribes and basic recordation have been completed; all documentation
should be at a level of standard professional practice to allow the writing of a report of professional quality;
b. A curation agreement with an appropriate qualified
repository within San Bernardino County that meets federal standards per 36 CFR Part 79 and therefore would be
professionally curated and made available to other
archaeologists/researchers for further study. The
collections and associated records shall be transferred, including title, to an appropriate curation facility within San Bernardino County, to be accompanied by payment of the
fees necessary for permanent curation;
c. For purposes of conflict resolution, if more than one Native American tribe or band is involved with the project and cannot come to an agreement as to the disposition of
cultural materials, they shall be curated at the San
Bernardino County Museum by default;
d. At the completion of grading, excavation and ground
disturbing activities on the site, a Phase IV Monitoring Report shall be submitted to the City documenting
monitoring activities conducted by the project archaeologist and Native Tribal Monitors within 60 days of completion of grading. This report shall document the impacts to the
known resources on the property; describe how each
mitigation measure was fulfilled; document the type of
cultural resources recovered and the disposition of such resources; provide evidence of the required cultural
sensitivity training for the construction staff held during the required pre-grade meeting; and, in a confidential
appendix, include the daily/weekly monitoring notes from the archaeologist. All reports produced will be submitted to the City, County Museum, and consulting tribes.

Mitigation Measure TCR-3. During construction activities, the project applicant shall allow additional archaeological monitors of Native American tribes to access the project site on a volunteer basis to monitor grading and excavation activities.

City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Introduction
1-1

1.0 INTRODUCTION

1.1 OVERVIEW OF THE CEQA PROCESS
This Draft Supplemental Environmental Impact Report (SEIR) is prepared in accordance with the California Environmental Quality Act (CEQA) to evaluate potential environmental impacts associated with the implementation of the City of Corona General Plan Housing Element Rezoning Program Update Project (Project). This document is prepared in conformance with CEQA (California PRC Section 21000, et seq.) and the CEQA Guidelines (California Code of Regulations [CCR], Title 14, Section 15000, et seq.). This Draft SEIR is intended to serve as an informational document for the public agency decision makers and the public regarding the Project.

1.1.1 Overview
The City’s General Plan Update Environmental Impact Report (EIR) anticipated an additional 5,494 residential units within the City through buildout of the General Plan. However, the Regional Housing Needs Allocation (RHNA) allocation for the Housing Element Update exceeds the City’s housing unit projection for Year 2040 in the General Plan Update. Currently, the City’s RHNA allocation of 6,088 units exceeds its projected housing growth by 594 units, in addition to accommodating an additional buffer.

Therefore, the City is proposing a rezoning program to accommodate the planning of additional low- and moderate-income households as required by the state’s RHNA allocation for the City. The additional 594 housing units from the RHNA were not known at the time the General Plan Update EIR was prepared, potentially resulting in additional impacts that were not evaluated in the General Plan Update EIR. As such, supplemental environmental evaluation is required pursuant to CEQA to address the potential impacts from growth that could occur as a result of future Project implementation. Therefore, this SEIR analyzes the additional RHNA allocation and planned buffer for additional housing that was not analyzed in the City’s General Plan Update EIR.

1.1.2 Purpose and Authority
The City of Corona (City), as the Lead Agency, has prepared this Draft Supplemental Environmental Impact Report (SEIR) to the Corona General Plan Technical Update 2020 Final Environmental Impact Report (FEIR) for the City of Corona General Plan Housing Element Rezoning Program Update Project (Project) in compliance with the California Environmental Quality Act (CEQA) and the CEQA Guidelines.

As provided in Section 15121(a) of the CEQA Guidelines, “An EIR is an informational document which will inform public agency decision makers and the public generally of the significant environmental effect of a project, identify possible ways to minimize the significant effects, and describe reasonable alternatives to the project. The public agency shall consider the information in the EIR along with other information which may be presented to the agency.”
As the CEQA Lead Agency for this Project, the City is required to consider the information in the EIR along with any other available information in deciding whether to approve the project. In accordance with CEQA, City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Introduction
1-2
this SEIR provides objective information regarding the environmental impacts of the Project to the decisionmakers who will be considering Project approval. As provided in the CEQA Guidelines, the basic requirements for an EIR include discussions of the environmental setting, significant environmental impacts including growth-inducing impacts, cumulative impacts, mitigation measures, and alternatives. It is not the intent of an EIR to recommend either approval or denial of a project.

The CEQA Guidelines contain the following general information of the role of an EIR and its contents:

Section 15145 – Speculation. If, after thorough investigation, a Lead Agency finds that a particular impact is too speculative for evaluation, the agency should note its conclusion and terminate discussion of the impact.

Section 15151 – Standards for Adequacy of an EIR. An EIR should be prepared with a sufficient degree of analysis to provide decision-makers with information that enables them to make a decision that intelligently considers environmental consequences. An evaluation of the environmental effects of the proposed project need not be exhaustive, but the sufficiency of an EIR is to be reviewed in light of what is reasonably feasible. Disagreement among experts does not make an EIR inadequate, but the EIR should summarize the main points of disagreement among the experts. The courts have looked not for perfection, but for adequacy, completeness, and a good-faith effort at full disclosure.

1.1.3 Type of Environmental Impact Report
This a Supplemental EIR. Pursuant to CEQA Guidelines Section 15162, when an EIR has been certified for a project, no subsequent EIR shall be prepared for that project unless the lead agency determines one or more of the following:
• Substantial changes are proposed in the project which will require major revisions of the previous EIR due to involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects;
• Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or
• New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as completed, shows any of the following:
o The project will have one or more significant effects not discussed in the previous EIR; o Significant effects previously examined will be substantially more severe than shown in the previous EIR;
City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Introduction
1-3
o Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantial reduce one or more significant effects of the project. But the project proponents decline to adopt the mitigation measures or alternatives; or o Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.

Under CEQA Guidelines Section 15163, the lead or responsible agency may choose to prepare a supplemental EIR rather than subsequent EIR if:
• Any of the conditions described in Section 15162 would require the preparation of a subsequent EIR, and
• Only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation.

The City, as the lead agency, has decided to prepare a SEIR as it would adequately address impacts from minor changes to the Corona General Plan Technical Update 2020 FEIR resulting from the Project. As required by CEQA, this SEIR will only contain the information necessary to analyze the project modifications, changed circumstances, or new information that triggered the need for additional environmental review. The SEIR will only contain the information necessary to make the previous EIR adequate for the project as revised, shall be given the same kind of notice and public review as is given to the draft EIR under CEQA Guidelines Section 15087, and may be circulated by itself without re-circulation the previous draft or final EIR.

1.1.4 Lead Agency Determination
The City of Corona is designated as the lead agency for the Project. CEQA Guidelines Section 15367 defines the lead agency as “the public agency, which has the principal authority for carrying out or approving a project.” Other public agencies may use this Draft SEIR in the decision-making or permit process and consider the information in the Draft SEIR along with other information that may be presented during the CEQA process.

This Draft SEIR was prepared by the City with technical assistance provided by Stantec Consulting Services Inc. (Stantec), an environmental consultant. Prior to public review, this Draft SEIR was extensively reviewed and evaluated by the City staff and, as such, the Draft SEIR reflects the independent judgement and analysis of the City as required by CEQA. List of organizations and persons consulted, and the report preparation personnel, are provided in Section 8.0 of this Draft SEIR.

1.1.5 Project of Statewide, Regional or Areawide Environmental Significance CEQA Guidelines Section 15206 identifies the types of projects considered to be of Statewide, Regional, or Areawide Significance. When a project is classified, its draft EIR shall be submitted to the State Clearinghouse of the Governor’s Office of Planning and Research (OPR), as well as the appropriate metropolitan area council of government.

City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Introduction
1-4
The Project meets the following criteria defining projects of Statewide, Regional, or Areawide Significance:
• A proposed local general plan, element, or amendment thereof, for which an EIR was prepared.

1.2 SCOPE OF THE SEIR

1.2.1 Notice of Preparation and Scoping
Pursuant to CEQA and CEQA Guidelines, a lead agency shall focus an EIR discussion on potentially significant environmental effects and may limit discussion on other effects to brief explanations about why they are not significant (PRC Section 21002.1, CEQA Guidelines Section 15128). A determination of which impacts would be potentially significant was made for this project based on review of the information presented in the Initial Study prepared for the Project and comments received as part of the public scoping process (Appendix A), as well as additional research of relevant project data obtained during preparation of this SEIR. This SEIR addresses the potential environmental effects of the Project. The City distributed a Notice of Preparation (NOP) and Initial Study (IS) of a Draft SEIR for the Project beginning on July 1, 2022.

The public scoping meeting on the Draft SEIR for the Project was held on July 20, 2022. The comments received on the NOP were considered in the preparation of this Draft SEIR. The scope of this Draft SEIR includes the potential impacts identified in the NOP and issues raised by agencies and the public in response to the NOP.

The City has determined that the Project has the potential to result in significant environmental impacts on the following resources, which are addressed in detail in this Draft SEIR. • Air Quality
• Energy
• Greenhouse Gas Emissions
• Land Use and Planning
• Noise
• Public Services
• Recreation
• Transportation
• Tribal Cultural Resources
Please refer to Section 1.2.2, Environmental Issues Determined Not to be Significant, for a list of environmental issues determined to be not significant.

1.2.2 Environmental Issues Determined Not to be Significant Pursuant to CEQA, the discussion of the potential effects on the physical environment is focused on those impacts that may be significant or potentially significant. CEQA allows a lead agency to limit the details of discussion of the environmental effects that are not considered potentially significant (PRC Section 21100, CEQA Guidelines Section 15126.2[a] and 15128). CEQA requires that the discussion of any significant effects on the environment be limited to substantia or potentially substantial adverse changes in physical conditions that exist within the affected area, as defined in PRC Section 21060.5. Effects dismissed in an analysis as clearly insignificant and unlikely to occur need not be discussed further in the draft EIR unless the lead agency subsequently receives information inconsistent with the finding (CEQA Guidelines Section 15143).

In addition, certain subjects within various environmental resource topics were determined not to be significant. Other potentially significant issues are analyzed within these environmental resource topics; however, the following issues are not analyzed:
• Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? (Section

3.6, Energy)
• For a project located within the vicinity of a private airstrip or an airport land use plan, or where such a plan has not been adopted within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? (Section 3.13, Noise)
• Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:
o Fire protection?
o Police protection?
o Schools?
o Other public facilities? (Section 3.15, Public Services) • Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersection(s) or incompatible uses (e.g. farm equipment))? (Section 3.17, Transportation) • Result in inadequate emergency access? (Section 3.17, Transportation)

2.0 PROJECT INFORMATION AND DESCRIPTION

2.1 PROJECT DESCRIPTION

2.1.1 Proposed AHO and Rezoning Program
The City’s General Plan was recently updated in 2020 and included adoption of the City of Corona General Plan Update Environmental Impact Report (General Plan EIR), a Programmatic EIR certified on June 30, 2020. As part of the General Plan Update effort, the City’s 2021-2029 Draft Housing Element was adopted by the City Council on November 3, 2021, and has been reviewed by the California Department of Housing and Community Development (HCD). The City is continuing to work with HCD on obtaining Housing Element compliance.

The General Plan Update EIR anticipated an additional 5,494 residential units; however, the RHNA allocation for the Housing Element Update now exceeds the City’s housing unit projection for Year 2040 in the General Plan Update. The City’s total RHNA allocation is 6,088 units with 3,888 allocated to low- and moderate-income housing units, consisting of 2,792 units and 1,096 units, respectively. Currently the City’s RHNA allocation of 6,088 exceeds it projected housing growth by 594 units, in addition to accommodating an additional buffer.

As such, the City is now proposing a rezoning program to accommodate the planning of low- and moderateincome households as required by the state’s RHNA allocation for the City. These additional 594 housing units from the RHNA were not known at the time of the General Plan Update EIR. Therefore, supplemental environmental evaluation pursuant to CEQA is required to address the potential impacts from growth that could occur as a result of Project implementation.

The proposed Project is ultimately implementing the General Plan. As such, the General Plan Update EIR is incorporated by reference herein, as the evaluations of potential environmental impacts associated with adoption of the General Plan include mitigation measures and consistency evaluations which are directly applicable to the proposed Project.

The City’s Housing Element Update includes an inventory of properties that are intended to be rezoned to high density residential or an AHO zone in order to plan for potential site to accommodate the RHNA allocation of units that would also be suitable for low- and moderate- income units. The AHO zone is a new zone being proposed by the City to establish by-right development standards for affordable housing projects. The AHO zone will cover existing properties that are currently developed with non-residential land uses. General Plan designations and zoning would remain, with overlays added, which would allow property owners to have the option to develop under either set of standards (the underlying General Plan and zoning or the AHO). The City is proposing to create development standards (i.e., criteria for building setbacks, parking, building height, landscaping, open space amenities, lot coverage, etc.) and architectural design guidelines for the AHO zone.

Project Information and Description

In addition to the RNHA allocation, a buffer is necessary to ensure that if one or more of the identified candidate sites are developed at lower densities or with non-housing uses, there would be remaining capacity to ensure an ongoing supply of site for housing during the eight-year-cycle of the Housing Element.

If there were no buffer provided, then the City could be obliged to identify new sites and amend the Housing Element if an identified site were developed with a non-housing project or developed at a density less than that anticipated in the Housing Element. The need for a substantial buffer is even more important during this cycle because of new rules in the Housing Accountability Act’s “non net loss” provisions. Senate Bill (SB) 166 (2017) requires that the land inventory and site identification programs in the Housing Element always include sufficient sites to accommodate the unmet RHNA. This means that if a site identified in the Housing Element as having the potential to accommodate the lower-income housing portion of the RHNA is actually developed for higher income level, the locality must either: 1) identify and rezone, if necessary, and adequate substitute site; or 2) demonstrate that the land inventory already contains an adequate substitute site. Providing an adequate buffer is necessary to ensuring that the City remains complaint with the provisions of SB 166.

2.2 PROJECT LOCATION
The Project is located in the City of Corona (Corona), which is in northwestern Riverside County (County).

The City is generally bordered by the City of Norco and the City of Riverside to the north and northeast, the City of Chino Hills and the City of Yorba Linda to the northwest, the City of Anaheim to the west, the Cleveland National Forest and the Santa Ana Mountains to the southwest, and unincorporated Riverside County along the remaining City borders, as shown in Figure 1. The Project is interspersed throughout the City, which has a land area of approximately 40 square miles, as shown in Figure 2. The Project would affect specific parcels within the City, by proposing to rezone parcels to accommodate high density residential uses or an Affordable Housing Overlay (AHO) zone in order to plan for additional affordable housing units, as shown in Figure 3.

2.2.1 Current Site Conditions
The Project site expands across various urban and suburban areas of the City, as shown in Figure 3. AHO properties fall within the North Main Specific Plan and the Downtown Revitalization Specific Plan. The North Main Street District Specific Plan was adopted in 2000 to guide future development for properties within the Specific Plan area north of Grand Boulevard. The Downtown Revitalization Specific Plan (1998) for the City of Corona serves to guide and shape future development of downtown over the next 10 to 15 years. The City has identified a number of potential sites for the proposed AHO zone and for rezoning. Current General Plan land use designations and proposed zoning are defined in Table 2.2-1 below.

2.2.2 Surrounding Land Uses
As the existing land uses are comprised of a variety of land uses across the City, the surrounding land uses are similarly varied in character. They consist of residential development, vacant land, commercial and retail uses, parking lots, mobile home parks, institutional and industrial uses, as well as other urban and suburban land uses throughout the City.

2.2.3 Candidate Sites and Characteristics
An important component of the City’s Housing Element Update is the identification of sites for future housing development, and an evaluation of the adequacy of those sites in fulfilling the City’s share of regional housing needs. To accomplish this, all City parcels were surveyed to determine their development capacity.

Due to the lack of vacant and underutilized sites in the City, candidate sites were selected for rezoning.

Each site was analyzed in light of the development standards for its proposed zoning designation.

2.2.3.1 Character Zones
The opportunity sites identified in the City’s Housing Element are clustered along the City’s 6th Street corridor in addition to clusters near N. Main Street. These and other clusters represent “character zones” that generally have consistent land use patterns, architectural character, housing densities, and circulation that inform the urban design qualities of the surrounding area. The four character zones are summarized below and shown in Figure 4.

The West Corona Character Zone (Character Zone 1) is clustered along W. 6th Street and defined by strip malls, auto-oriented commercial development, multi-family apartments, and its proximity to State Route 91.

Large industrial lots also dominate West Corona.

The Downtown Corona Character Zone (Character Zone 2) consists of a wide array of building typologies, including single family residential homes, auto-oriented commercial, institutional, and religious buildings.

AHO and rezone properties identified in this zone are located with the City’s Downtown Revitalization Specific Plan. In addition to Grand Boulevard, several historic places are located in Character Zone 2, including Corona High School, Andrew Carnegie Library, and the Woman’s Improvement Club.

The North Corona Character Zone (Character Zone 3) consists of auto-oriented commercial and industrial properties directly north of the Corona North Main Link Metrolink Station and several vacant, industrial properties to the west, along Railroad Street. Recent multi-family housing projects, including Metro and Main and Artisan and Main Street are located within Character Zone 3. T The East Corona Character Zone (Character Zone 4) is clustered around E. 6th Street, near Interstate 15.

Character Zone 4 is defined by vacant industrial lots, warehouse and manufacturing typologies, mobile home communities, low-rise apartments, single family residential uses and auto-oriented commercial uses.

There are three rezone properties that fall outside of these four zones. Two of the sites are existing churchowned properties, located south of Grand Boulevard among single family residential neighborhood. The third property consists of a mobile home community on the eastern side of Character Zone 4.

2.2.3.2 Transit Oriented Development
The proposed Project is developed to be most compatible for residential development within a High Quality Transit Area (HQTA). The Southern California Association of Governments (SCAG) defines HQTAs as corridor-focused priority growth areas that are within one-half mile of an existing or planned fixed guideway transit stop or bus transit corridor that has a frequency of every 15 minutes or less during peak commuting hours. These standards aim to support the highest density for the proposed Project, as they are intended to encourage compact development, improve access to transit, and promote a pedestrian-oriented environment. Transit-oriented community development standards would require a minimum of 60 units per acre, as provided by the proposed Project. The location of the candidate sites in relation to the HQTA is shown in Figure 5.

2.2.3.3 Candidate Sites
All parcels in the City were evaluated through a process of elimination based on required criteria set by HCD. Candidate sites that are proposed for the AHO zone include a variety of uses on 100 parcels, including commercial, retail, industrial, surface parking, storage and vacant parcels, as described in Table

2.3-1 below. In the proposed AHO zone, residential uses will be allowed on sites currently designated as MU2 on the General Plan. Sites in the MU1 zones are permitted to be entirely for residential use zone, if located in the proposed AHO zone. There are 57 parcels considered as potential sites for proposed rezoning, and these are primarily parcels that are currently used for residential uses, in addition to parking lots, mobile home parks and some commercial, institutional, and vacant parcels, as described in Table 2.3- 2 below.

2.3 PROJECT COMPONENTS
The City’s RHNA allocation for the current cycle calls for accommodating 6,088 units at low-, moderate-, and above moderate-income levels. Of this total allocation, there are planned, recently approved, or Accessory Dwelling Units (ADUs) that are anticipated for development, which can be counted towards the City’s overall unit requirement. To enable the production of units needed to meet the overall unit requirements, the proposed Project has identified vacant units located in existing buildings and is proposing to rezone or apply a new AHO to select properties.

As shown in Table 2.3-1 below, vacant parcels (750 units) and nonvacant parcels (452 units) can accommodate a total of approximately 1,202 new housing units, and potential rezone parcels (368 units) and AHO parcels (4,651 units) at a maximum density of 60 units per acre can accommodate a total of approximately 6,221 additional housing units. Based on this, by implementing the Project, the City would be able to accommodate the 2021-2029 RHNA and provide a RHNA-buffer of 39.5 percent for low-income households and 32 percent for moderate-income households.

2.4 PROJECT OBJECTIVES
Pursuant to CEQA Guidelines Section 15124, the EIR must identify the objectives sought by the Project.

The stated objectives of the Project proponent are to:

1. Implement the 2021-2029 Housing Element Programs to provide adequate housing sites for all income levels within the City.

2. Promote housing opportunities that support the City’s state mandated Regional Housing Needs Assessment.

3. Promote fair housing opportunities that encourage access to lower- and moderate-income housing.

4. Promote safe and healthy housing opportunities to discourage overcrowding.

2.5 USES OF THE SEIR
This SEIR is intended to provide the City of Corona, other public agencies, and the general public with the relevant environmental information needed in considering the proposed project. The City of Corona anticipates the permits approvals, and consultations, but are not limited to, the actions described in Table

2.5-1 below.

Environmental Setting, Impacts and Mitigation
3-1

3.0 ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION
This section presents the discussion of impacts related to the following environmental subjects in their respective subsection:
• Air Quality • Recreation
• Energy • Noise
• Greenhouse Gas Emissions • Transportation
• Land Use • Tribal Cultural Resources
• Public Services
The discussion for each environmental subject includes the following subsections:

Environmental Setting – This subsection 1) provides a brief overview of relevant plans, policies, and regulations that compose the regulatory framework for the project and 2) describes the existing, physical environmental conditions at the project site and in the surrounding area, as relevant.

Impact Discussion – This subsection includes the recommended checklist questions from Appendix G of the CEQA Guidelines to assess impact.

Project Impacts – This subsection discusses the project’s impact on the environmental subject as related to the checklist questions. For significant impacts, feasible mitigation measures are identified. “Mitigation measures” are measures that will minimize, avoid, or eliminate a significant impact (CEQA Guidelines Section 15370).

Impact Conclusions – Because the analysis in the SEIR tiers from the FEIR, the level of impact in the project specific analysis is presented as it relates to the findings of the FEIR. For example, if the conclusions is “Same Impact as Approved Project/Less than Significant Impact” the project level impact was found to be less than significant consistent with the finding in the FEIR.

Cumulative Impact – This subsection discusses the project’s cumulative impact on the environmental subject. Cumulative impacts, as defined by CEQA, refer to two or more individual effects, which when combined, compound or increase other environmental impacts. Cumulative impacts may result from individually minor, but collectively significant effects taking place over a period of time. CEQA Guidelines Section 15130 states that an EIR should discuss cumulative impacts “when the project’s incremental effect is cumulatively considerable.” The discussion does not need to be in as great detail as is necessary for project impacts but is to be “guided by the standards of practically and reasonableness.” The purpose of the cumulative analysis is to allow decision makers to better understand the impacts that might result from approval of past, present, and reasonably foreseeable future projects, in conjunction with the proposed project addressed in this SEIR.

The CEQA Guidelines advise that a discussion of cumulative impact should reflect both their severity and the likelihood of their occurrence (CEQA Guidelines Section 15130(b)). To accomplish these two objectives, the analysis should either include a list of past, present, and probable future projects or a summary of 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-2
projections from an adopted general plan or similar document (CEQA Guidelines Section 15130(b)(1)). This SIER uses the list of projects approach.

The analysis must determine whether the Project’s contribution to any cumulatively significant impact is cumulatively considerable, as defined by CEQA Guideline Section 15065(a)(3). The cumulative impacts discussion for each environmental issue accordingly addresses the following issues: 1) would the effects of all of past, present, and probably future (pending) development result in a significant cumulative impact on the resource in question; and, if that cumulative impact is likely to be significant, 2) would the contribution from the Project to that significant cumulative impact be cumulatively considerable? Table 3.0-1 identifies the approved but not yet contrasted/occupied and pending projects in the Project vicinity that are considered in the cumulative analysis.

3.1 AIR QUALITY

3.1.1 Environmental Setting
The City is within the South Coast Air Basin (SoCAB), which includes all of Orange County and the nondesert portions of Los Angeles, Riverside, and San Bernadino Counties. SoCAB is designated nonattainment for ozone (O3) and fine inhalable particulate matter (PM2.5) under the California Ambient Air Quality Standards (CAAQS) and National Ambient Air Quality Standards (NAAQS), nonattainment for lead (Los Angeles County only) under the NAAQS, and nonattainment for coarse inhalable particulate matter (PM10) under the CAAQS (City of Corona 2019).

The South Coast Air Quality Management District (SCAQMD) is responsible for preparing the air quality management plan (AQMP) for the SoCAB in coordination with SCAG to attain the NAAQS. In March 2017, SCAQMD adopted the 2016 AQMP which is composed of stationary and mobile-source emission reductions from regulatory control measures, incentive-based programs, co-benefits from climate programs, mobile-source strategies, and reductions from federal sources such as aircrafts, locomotives, and ocean-going vessels. Strategies outlined in the 2016 AQMP would be implemented in collaboration between California Air Resources Board (CARB) and the United States Environmental Protection Agency (USEPA). SCAQMD’s 2016 AQMP forecasts that the SoCAB will need to increase oxides of nitrogen (NOx) reductions by 45 percent additional reductions above existing regulations for the 2023 ozone standard and 55 percent additional reductions above existing regulations to meet the 2031 ozone standard.

3.1.1.1 Regulatory Framework
Federal
Clean Air Act
The Clean Air Act (CAA) of 1970 and the CAA Amendments of 1971 required the U.S. Environmental Protection Agency (USEPA) to establish NAAQS, with requires retaining the option to adopt more stringent standards or to include other specific pollutants. On April 2, 2007, the Supreme Court found that carbon dioxide is an air pollutant covered by the CAA; however, no NAAQS have been established for carbon dioxide.

These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those “sensitive receptors” most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed.

The federal and state ambient air quality standards are listed below in Table 3.1-1, and the attainment status for the criteria pollutants are listed in Table 3.1-2. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

The USEPA has classified air basins (or portions thereof) as being in attainment, nonattainment, or unclassified for each criteria air pollutant, based on whether or not the NAAQS have been achieved. If an area is designated as unclassified, it is because inadequate air quality data were available as a basis for a nonattainment or attainment designation.

National Ambient Air Quality Standards
The CAA required USEPA to establish NAAQS. As shown in Table 3.1-1, USEPA has established primary and secondary NAAQS for the following criteria air pollutants: O3, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), PM10, PM2.5, and lead. The primary standards protect the public health, and the secondary standards protect public welfare. The CAA also required each state to prepare an air quality control plan, referred to as a State Implementation Plan (SIP). The federal CAA amendments of 1990 added requirements for states with nonattainment areas to revise their SIPs to incorporate additional control measures to reduce air pollution. The SIP is modified periodically to reflect the latest emissions inventories, planning documents, and rules and regulations of the air basins as reported by their jurisdictional agencies.

USEPA is responsible for reviewing all SIPs to determine whether they conform to the mandates of the CAA and its amendments, and whether implementation would achieve air quality goals. If USEPA determines a SIP to be inadequate, a federal implementation plan that imposes additional control measures may be prepared for the nonattainment area. If an approvable SIP is not submitted or implemented within the mandated timeframe, sanctions may be applied to transportation funding and stationary air pollution sources in the air basin.

Hazardous Air Pollutants
USEPA and CARB regulate hazardous air pollutants (HAPs) and TACs through statutes and regulations that generally require the use of the maximum available control technology or best available control technology for TACs to limit emissions, respectively. These, in conjunction with additional rules set forth by BAAQMD, described further below, establish the regulatory framework for TACs.

Under federal law, 187 substances are currently listed as HAPs. Major sources of specific HAPs are subject to the requirements of the National Emissions Standards for Hazardous Air Pollutants (NESHAPS) program. The USEPA is establishing regulatory schemes for specific source categories and requires implementation of the Maximum Achievable Control Technologies (MACT) for major sources of HAPs in each source category. State law has established the framework for California’s TAC identification and control program, which is generally more stringent than the federal program and is aimed at HAPs that are a problem is California. The state has formally identified 244 substances as TACs and is adopting appropriate control measures for each. Once adopted at the state level, each air district will be required to adopt a measure that is equally or more stringent.

State
The California Legislature enacted the California Clean Air Act (CCAA) in 1988 to address air quality issues.

CARB is the agency responsible for coordination and oversight of state and local air pollution control programs in California and for implementing the CCAA. California law authorizes CARB to set ambient (outdoor) air pollution standards (California Health and Safety Code [HSC] Section 39606) in consideration of public health, safety, and welfare (CAAQS) (Table 3.1-1).

California Clean Air Act of 1988
The California Clean Air Act allows the state to adopt ambient air quality standards and other regulations provided that they are at least as stringent as federal standards. CARB, a part of the California Environmental Protection Agency (CalEPA), is responsible for the coordination and administration of both federal and state air pollution programs within California and for implementing the CCAA. California law authorizes CARB to set ambient (outdoor) air pollution standards (California HSC Section 39606) in consideration of public health, safety, and welfare (Table 3.1-1).

California Ambient Air Quality Standards
CARB has established CAAQS for sulfates, hydrogen sulfide, vinyl chloride, visibility-reducing particulate matter, and the above-mentioned criteria air pollutants. In most cases, the CAAQS are more stringent than the NAAQS. Differences in the standards are generally explained by the health effects studies considered during the standard-setting process and the interpretation of the studies. In addition, the CAAQS incorporate a margin of safety to protect sensitive individuals.

CCAA requires that all local air districts in the state endeavor to achieve and maintain CAAQS by the earliest date practicable. CCAA specifies that local air districts should focus attention on reducing the 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-11
emissions from transportation and area-wide emission sources and provides districts with the authority to regulate indirect sources.

Among CARB’s other responsibilities are overseeing local air district compliance with federal and state laws, approving local air quality plans, submitting SIPs to CalEPA, monitoring air quality, determining and updating area designations and maps, and setting emissions standards for new mobile sources, consumer products, small utility engines, off-road vehicles, and fuels.

California State Implementation Plan
The federal CAA (and its subsequent amendments) requires each state to prepare an air quality control plan referred to as a SIP. The SIP is a living document that is periodically modified to reflect the latest emissions inventories, plans, and rules and regulations of air basins as reported by the agencies with jurisdiction over them. The CAA Amendments released in 1992 dictate that states containing areas violating the NAAQS revise their SIPs to include extra control measures to reduce air pollution. The SIP includes strategies and control measures to attain the NAAQS by deadlines established by the CAA. The CalEPA has the responsibility to review all SIPs to determine if they conform to the requirements of the CAA.

California Air Toxics “Hot Spots”
TACs in California are regulated primarily through the Tanner Air Toxics Act (Assembly Bill [AB] 1807, Chapter 1047, Statutes of 1983) and the Air Toxics “Hot Spots” Information and Assessment Act of 1987 (AB 2588, Chapter 1252, Statutes of 1987). AB 1807 sets forth a formal procedure for CARB to designate substances as TACs. Research, public participation, and scientific peer review are required before CARB can designate a substance as a TAC. To date, CARB has identified more than 21 TACs, including diesel particulate matter, and has adopted USEPA’s list of HAPs as TACs.

Once a TAC is identified, CARB adopts an airborne toxics control measure for sources that emit that particular TAC. If a safe threshold exists for a substance at which there is no toxic effect, the control measure must reduce exposure below that threshold. If no safe threshold exists, the source must incorporate best available control technology for toxics to minimize emissions.

CARB has adopted diesel exhaust control measures and more stringent emission standards for various onroad mobile sources of emissions, including transit buses, and off-road diesel equipment (e.g., tractors, generators). Recent milestones included the low-sulfur diesel fuel requirement and stricter emissions standards for heavy-duty diesel trucks (effective in 2007 and subsequent model years) and off-road diesel equipment (2011). Over time, replacing older vehicles would result in a vehicle fleet that produces substantially lower levels of TACs than under current conditions. Mobile-source emissions of TACs (e.g., benzene, 1,3-butadiene, diesel particulate matter) in California have been reduced substantially over the last decade; such emissions will be reduced further through a progression of regulatory measures (e.g., low-emission vehicles, clean fuels, and Phase II reformulated-gasoline regulations) and control technologies.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-12
The Hot Spots Act requires that existing facilities that emit toxic substances above a specified level prepare an inventory of toxic emissions and a risk assessment if emissions are significant, notify the public of significant risk levels, and prepare and implement risk reduction measures.

In March 2015, the California Office of Environmental Health Hazard Assessment (OEHHA) adopted “The Air Toxics Hot Spots Program Guidance Manual for Preparation of Health Risk Assessments” in accordance with the Health and Safety Code, Section 44300. The Final Guidance Manual incorporates the scientific basis from earlier developed Technical Support Documents to assess risk from exposure to facility emissions. The 2015 OEHHA Final Guidance has key changes including greater age sensitivity in particular for children, decreased exposure durations, and higher breathing rate profiles. Because cancer risk could be up to three times greater using this new guidance, it may result in greater mitigation requirements, more agency backlog, and increased difficulty in getting air permits.

Regional
The State is divided into air pollution control districts/air quality management districts. These agencies are county or regional governing authorities that have primary responsibility for controlling air pollution from stationary sources. CARB and local air districts are also responsible for developing clean air plans to demonstrate how and when California will attain ambient air quality standards established under both the federal and California Clean Air Acts. For the areas within California that have not attained air quality standards, CARB works with air districts to develop and implement state and local attainment plans. In general, attainment plans contain a discussion of ambient air quality data and trends; a baseline emissions inventory; future year projections of emissions, which account for growth projections and already adopted control measures; a comprehensive control strategy of additional measures needed to reach attainment; an attainment demonstration, which generally involves complex modeling; and contingency measures.

Plans may also include interim milestones for progress toward attainment. The SoCAB is managed by SCAQMD.

SCAQMD Air Quality Management Planning
The SCAQMD is the air pollution control agency for all of Orange County and the urban portions of Los Angeles, Riverside, and San Bernadino counties. This area of 10,743 square miles is home to over 16.8 million people – about half the population of the whole state of California. It is the second most populated urban area in the United States and one of the smoggiest. The SCAQMD operates 37 permanent monitoring stations and 5 single-pollutant source impact lead (Pb) air monitoring sites in the SoCAB and a portion of the Salton Sea Air Basin in Coachella Valley.

The SCAQMD is the agency responsible for improving air quality in the SoCAB and ensuring that the NAAQS and CAAQS are attained and maintained. It is responsible for preparing the air quality management plan (AQMP) for the SoCAB in coordination with SCAG.

The SCAQMD’s most recent AQMP is the 2016 AQMP which was adopted on March 3, 2017. The SCAQMD is currently working on the 2022 AQMP. On October 1, 2015, the USEPA strengthened the NAAQS for ground-level ozone, lowering the primary and secondary ozone standards levels to 70 parts per billion. The SoCAB is classified as an “extreme” non-attainment area and the Coachella Valley is classified 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-13
as a “severe-15” non-attainment area for the 2015 Ozone NAAQS. The 2022 AQMP is being developed to address the requirements for meeting this standard. The 2022 AQMP will represent a comprehensive analysis of emissions, meteorology, regional air quality modeling, regional growth projections, and the impact of existing and proposed control measures.

Local
City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and air quality discussed in this section:

Policy HC-2.1: Require that proposals for new sensitive land uses and/or industrial and commercial uses incorporate the adequate use of setbacks, barriers, landscaping, or other design measures as necessary to minimize air quality impact and achieve appropriate health standards.

Policy HC-2.5: Require the preparation of air quality, noise, and vibration technical studies to determine the impact of proposed new development on adjacent and surrounding land uses and to identify the appropriate measures required to mitigate such impacts.

Policy ER-12.2: Continue to cooperate with the SCAQMD and other local authorities in the air basin, in implementing air emission reduction programs and techniques.

3.1.2 Impact Discussion

3.1.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following questions were analyzed and evaluated to determine whether impacts to air quality are significant environmental effects.

Where available, the significance criteria established by the applicable air quality management or air pollution district may be relied upon to make the following determinations.

Would the Project:
• Conflict with or obstruct implementation of the applicable air quality plan? • Result in a cumulatively considerable net increase of any criteria pollutants for which the Project region is non-attainment under an applicable federal or state ambient air quality standard? • Expose sensitive receptors to substantial pollutant concentration? • Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?

Regional Thresholds
While the final determination of whether a project is significant is within the purview of the Lead Agency pursuant to Section 15064(b) of the CEQA Guidelines, the SCAQMD recommends that its quantitative air pollution thresholds (shown in Table 3.1-3) be used to determine the significance of project emissions. If the Lead Agency finds that the Project has the potential to exceed these air pollution thresholds, the Project should be considered to have significant air quality impacts.

Projects that exceed the regional significance threshold contribute to the nonattainment designation of the SoCAB.

Localized Significance Thresholds
The SCAQMD identifies localized significance thresholds (LSTs) shown in Table 3.1-4. Emissions of NO2, CO, PM10, and PM2.5 generated at a project site (offsite mobile source emissions are not included in the LST analysis) could expose sensitive receptors to substantial concentrations of criteria air pollutants. A project that generates emissions that trigger a violation of the ambient air quality standards when added to the local background concentrations would cause a significant impact.

1. Based on the more restrictive California AAQS for CO and NO2.

2. Threshold is based on SCAQMD Rule 403. Since the SoCAB is in nonattainment for PM10 and PM2.5, the threshold is established as an allowable change in concentration. Therefore, background concentration is not relevant.

CO Hotspots
Areas of vehicle congestion have the potential to cause concentrations of carbon monoxide (CO) that exceed ambient air quality standards and are called hotspots. Hotspots are typically produced at intersections where traffic congestion is highest because vehicles queue for longer periods of time at reduced speeds. Newer vehicle fleets, cleaner fuels, and advanced control technologies have greatly reduced CO concentrations in the SoCAB.

Health Risk Analysis
A health risk analysis is required of projects that require the use of chemical compounds identified in SCAQMD Rule 1401 or placed on the California Air Resources Board’s (CARB) air toxics list pursuant to AB 1807, the Air Contaminant Identification and Control Act (1983) or placed on the EPA’s National Emissions Standards for Hazardous Air Pollutants. SCAQMD has identified the following risk thresholds.

Table 3.1-5: SCAQMD Toxic Air Contaminant Incremental Risk Thresholds Category Threshold
Maximum Individual Cancer Risk ≥ 10 in 1 million
Cancer Burden (in areas ≥ 1 in 1 million) > 0.5 excess cancer cases Hazard Index (project increment) ≥ 1.0
Source: SCAQMD, 2022
Residential uses do not use substantial quantities of toxic air contaminants (TACs) and typically do not exacerbate existing hazards. Therefore, these thresholds are typically applied to new industrial projects.

3.1.2.2 Project Impacts
Would the Project conflict with or obstruct implementation of the applicable air quality plan? Finding: Same Impact as Approved Project (Significant and Unavoidable Impact) The SCAQMD is responsible for reducing emissions from area, stationary, and mobile sources in the SoCAB to achieve the NAAQS and CAAQS and prepares an air quality management plan (AQMP). The most current adopted plan is the 2016 AQMP, which is a regional and multiagency effort between the SCAQMD, CARB, SCAG, and the USEPA. The 2016 AQMP includes stationary and mobile-source -

-
-
I
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-16
emission reductions from regulatory control measures, incentive-based programs, co-benefits from climate programs, mobile-source strategies, and reductions from federal sources such as aircrafts, locomotives, and ocean-going vessels. The 2016 AQMP forecasts that the SoCAB will need to increase oxides of nitrogen (NOx) reductions by an additional 45 percent above existing regulations to meet the 2023 ozone standard and 55 percent additional reductions above existing regulations to meet the 2031 ozone standard.

The SCAQMD released its Draft 2022 AQMP in May 2022. The Draft 2022 AQMP includes a variety of strategies relying on NOx emissions reductions through economy-wide transition to zero emission technologies when cost-effective and feasible, and ultra-low emission technologies in other applications, best management practices, co-benefits from existing programs such as climate and energy efficiency policies, and incentive approaches where applicable. The Draft 2022 AQMP also includes a voluntary reclassification request to “extreme” nonattainment for the Coachella Valley to provide additional time for that area to meet the standard, extending the deadline to 2037.

The two principal criteria for evaluating conformance with the AQMP are:

1. Whether the project would exceed the assumptions in the AQMP.

2. Whether the project would result in an increase in the frequency or severity of existing air quality violations, cause or contribute to new violations, or delay attainment of air quality standards.

Criterion 1
Both the 2016 and Draft 2022 AQMP rely on economic and demographic projections developed by SCAG in its Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). Because the AQMP strategy is projections from local general plans, projects that are consistent with the local general plan are considered consistent with the air quality-related regional plan.

The City of Corona 2019 General Plan Update EIR found that the General Plan Update would result in higher population and lower employment for the City of Corona compared to the SCAG projections. Thus, it would not be consistent with projections used in estimating emissions in the 2016 AQMP. The General Plan EIR concluded that once the General Plan Update was adopted and the AQMP revised, SCAG and SCAQMD would incorporate the revised growth projections in their regional planning projections and the General Plan Update would become consistent with the AQMP. However, until that time, the full buildout of the General Plan Update would not be consistent with the AQMP.

The 2022 Draft AQMP presumably includes the General Plan Update growth projections in its emissions inventory; however, the population growth associated with future residential development resulting from Project implementation would increase the growth projections slightly so that full buildout of the General Plan with Project implementation would not be consistent with the AQMP.

Criterion 2
The SoCAB is designated nonattainment for O3 and PM2.5 under the CAAQS and NAAQS, nonattainment for lead (Los Angeles County only) under the NAAQS, and nonattainment for PM10 under the CAAQS 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-17
(CARB 2022). As shown in Table 5.3-10 of the 2019 General Plan Update EIR, buildout of the General Plan would generate long-term emissions that exceed the daily SCAQMD thresholds for VOC, NOx, PM10, and PM2.5. The emissions from the General Plan Update would contribute cumulatively to the nonattainment designations in the SoCAB, which would result in a significant air quality impact and not be consistent with the AQMP under the second criterion.

As shown in Table 2 of Appendix A, VOC, NOx, PM10, and PM2.5 emissions would increase slightly, but Project implementation would still result in a net reduction of NOx, CO, and SO2. Overall, buildout of the General Plan Update including Project implementation would still result in long-term emissions that exceed the daily SCAQMD thresholds for VOC, NOx, PM10, and PM2.5. As such, future development resulting from Project implementation would cumulatively contribute to the nonattainment status in the SoCAB, which would result in a significant air quality impact and not be consistent with the AQMP under the second criterion.

Conclusion
As identified above, Project implementation would conflict with or obstruct implementation of the applicable AQMP and would result in a significant impact. Implementation of General Plan Update EIR Mitigation Measures AQ-1 and AQ-2 would slightly reduce impacts; however, impacts would not be reduced to below the threshold of significance, and the impacts would remain significant and unavoidable, as noted in the General Plan Update EIR.

Would the Project result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is non-attainment under an applicable Federal or State ambient air quality standard?
Finding: Same Impact as Approved Project (Significant and Unavoidable Impact) To result in a less than significant impact, the following criteria must be true:

1. Regional analysis: emissions of nonattainment pollutants must be below the SCAQMD’s regional significance thresholds.

2. Summary of projections: the project must be consistent with current air AQMPs including control measures and regulations. This is an approach consistent with Section 15130(b) of the CEQA Guidelines.

Step 1: Regional Analysis
Construction
Construction activities associated with the future Project implementation would occur over the buildout horizon consistent with the General Plan Update, which would result in short-term emissions of criteria air pollutants. Because of the region’s nonattainment status for O3, PM2.5, and PM10, the primary pollutants of concern are VOCs, NOx, PM10, and PM2.5. Emissions of VOCs and NOx are precursors to the formation of O3. In addition, NOx is a precursor to the formation of PM10 and PM2.5. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-18
Due to the scale of development associated with future Project implementation, construction emissions would exceed SCAQMD regional significance thresholds, which would cumulatively contribute to the nonattainment designations of the SoCAB.

As discussed in the 2019 General Plan Update EIR, air quality emissions will be addressed on a projectby-project basis to determine if future individual development projects consistent with the rezoning and AHO would exceed the SCAQMD short-term regional construction emissions.

General Plan Policy ER-12.13 would require the implementation of best practices to control fugitive dust emissions from construction, and General Plan Policy HC-2.5 would require the preparation of a technical air quality study for all new development projects to assess potential impacts. While individual development projects may not exceed the SCAQMD thresholds, the construction-related regional air quality impacts of development associated with future development projects resulting from Project implementation would be potentially significant, similar to impacts associated with implementation of the General Plan Update.

Operations
Table 3.1-6 shows the long-term operational emissions from buildout of the General Plan with future implementation of the proposed Project, which would increase the number of dwelling units and population.

Like the General Plan Update, future Project implementation would help guide growth and development in the City by designating land where density intensification could occur.

(pounds per day)
VOC NOx CO SO2 PM10 PM2.5
Source: City of Corona, General Plan EIR 2019, Table 5.3-11 Net Change in Regional Emissions from the Existing Baseline Year 2018
As discussed above, the primary pollutants of concern are VOCs, NOx, PM10, and PM2.5. Emissions of VOCs and NOx are precursors to the formation of O3, and NOx is a precursor to the formation of PM10 and PM2.5. Buildout of the General Plan with future implementation of the proposed Project would result in longterm emissions that exceed the regional SCAQMD thresholds for VOC, NOx, CO, PM10, and PM2.5 and would contribute cumulatively to the nonattainment status of the SoCAB, thereby resulting in a potentially significant impact.

The General Plan includes many policies that would help to reduce emissions of criteria pollutants and implementation of General Plan EIR Mitigation Measures AQ-1 and AQ-2 would help to reduce impacts, but not to a less than significant level.

Step 2: Plan Approach
Section 15130(b) of the CEQA Guidelines states the following:

The following elements are necessary to an adequate discussion of significant cumulative impacts:
1) Either: (A) A list of past, present, and probable future projects producing related or cumulative impacts, including, if necessary, those projects outside the control of the agency, or (B) A summary of projections contained in an adopted general plan or related planning document, or in a prior environmental document which has been adopted or certified, which described or evaluated regional or area wide conditions contributing to the cumulative impact.

In accordance with CEQA Guidelines 15130(b), this analysis of cumulative impacts is based on a summary of projections analysis. The SoCAB is in nonattainment for O3, PM10, and PM2.5, which means that concentrations precursors and direct pollutants contribute to the current exceedance of the applicable ambient air quality standards.

Cumulative impacts may be analyzed using other plans that evaluate relevant cumulative effects. The geographic scope for cumulative criteria pollution from air quality impacts is the SoCAB because that is the area in which the air pollutants generated by the sources within the SoCAB circulate and are often trapped.

The SCAQMD is required to prepare and maintain air quality attainment plans and a SIP to document the strategies and measures to be undertaken to reach attainment of ambient air quality standards. While the SCAQMD does not have direct authority over land use decisions, it is recognized that changes in land use and circulation planning would help the SoCAB achieve clean air mandates. The SCAQMD evaluated emissions from land uses and transportation in the entire SoCAB when it developed its attainment plans.

In accordance with CEQA Guidelines Section 15064, subdivision (h)(3), a Lead Agency may determine that a project’s incremental contribution to a cumulative effect is not cumulatively considerable if the project complies with the requirements in a previously approved plan or mitigation program. ,---

The proposed Project would comply with applicable control measures identified in the AQMP; however, as discussed in Impact AIR-1, future Project implementation would not be consistent with the AQMP growth projections and emissions; thus, impacts would be potentially significant.

Conclusion
Project implementation would result in a cumulatively considerable net increase of VOCs, NOx, PM10, and PM2.5 for which the Project region is non-attainment under an applicable federal or State ambient air quality standard. Therefore, even with implementation of General Plan EIR Mitigation Measures AQ-1 and AQ-2, impacts would remain significant and unavoidable.

Would the Project expose sensitive receptors to substantial pollutant concentrations? Finding: Same Impact as Approved Project (Significant and Unavoidable Impact) The SCAQMD has developed construction and operational LSTs. Each is addressed below.

Construction
Future construction associated with Project implementation would occur over the same timeframe as the General Plan Horizon Year of 2040 or longer, through smaller individual development projects each with its own construction timeframe and equipment. The construction LST analysis requires project-specific information, such as project size, equipment, and schedule, such that a programmatic assessment is not feasible. Like the General Plan Update EIR, the proposed Project’s potential future development and redevelopment could occur close to existing sensitive receptors. Future development projects that would be accommodated by Project implementation have the potential to expose sensitive receptors to substantial pollutant concentrations. Construction equipment exhaust combined with fugitive particulate matter emissions has the potential to expose sensitive receptors to substantial concentrations of criteria air pollutant emissions and result in a significant impact.

While the implementation of applicable General Plan EIR Mitigation Measures AQ-1 and AQ-2 would serve to reduce the impact, on a regional basis, Project implementation would contribute to elevated levels of TACs in the air basin; as such, the impact would be significant and unavoidable.

Operations
Project implementation would permit more intense future development of residential uses within designated areas. The types of land uses that could generate substantial amounts of stationary source emissions include industrial land uses; as such, future Project implementation would have a less than significant impact in this regard.

Buildout of future residential development permitted by Project implementation could result in siting sensitive receptors (e.g., residences) near sources of emissions (e.g., freeways, industrial uses, etc.), which could expose sensitive receptors to potential air quality-related impacts. Like the evaluation conducted for the 2019 General Plan Update EIR, the purpose of this evaluation is to identify the significant effects of 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation

Project implementation on the environment, not the environment on the proposed Project. California Building Industry Association v. Bay Area Air Quality Management District (2015) 62 Cal.4th 369 (Case No.

S213478). Thus, CEQA does not require analysis of the potential environmental effects from siting sensitive receptors near existing sources, and this type of analysis is not provided.

While this analysis is not provided within the context of CEQA, the City of Corona General Plan Policy HC2.1 requires that new sensitive land uses incorporate setbacks, barriers, landscaping, or other design features to minimize air quality impacts and to achieve appropriate health standards. The following policies would be applicable:
• HC-2.1 Require that proposals for new sensitive land uses and/or industrial and commercial uses incorporate the adequate use of setbacks, barriers, landscaping, or other design measures as necessary to minimize air quality impacts and achieve appropriate health standards. • HC-2.7 Keep up to date on new and amended regulations issued by state and federal regulatory agencies with respect to air, water, and other pollutants and permissible exposure; revise local ordinances and development requirements as needed to reduce exposure to pollution.

CO Hotspots
The SoCAB is in attainment for CO under both the CAAQS and NAAQS. The CO hotspot analysis conducted for the attainment plan did not predict a violation of CO standards at the busiest intersections (Long Beach Boulevard and La Cienega Boulevard) in Los Angeles (daily traffic volume of over approximately 100,000 vehicles per day with LOS E) during the peak morning and afternoon periods.

The SCAQMD does not provide guidance for screening potential CO impacts but has accepted screening criteria developed by the Bay Area Air Quality Management District (BAAQMD), which determined that a project would have to increase traffic volumes at a single intersection by more than 44,000 vehicles per hour – or 24,000 vehicles per hour where vertical and/or horizontal air does not mix in order to generate a significant CO impact (BAAQMD 2017).

The General Plan Update EIR found that horizon year conditions would result in a maximum net increase of 2,460 peak hour trips which would be well below the screening criteria. Applying a 5.4 percent increase to the net trips based on the anticipated population growth would result in 2,593 trips, which would still be substantially less than the screening criteria. Therefore, implementation of the proposed Project would not produce a volume of traffic required to generate a CO hotspot, and this impact would be less than significant.

Would the Project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Finding: Less Impact than Approved Project (Less than Significant Impact) While offensive odors rarely cause any physical harm, they can still be very unpleasant, leading to considerable distress among the public and often generating citizen complaints to local governments and 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-22
the SCAQMD. The occurrence and severity of odor impacts depends on numerous factors, including nature, frequency, and intensity of the source, the wind speed and direction, and the sensitivity of the receptor.

Construction
Individual construction activities associated with future residential development associated with Project implementation could result in short-term odorous emissions from exhaust associated with construction equipment and application of asphalt and architectural coatings. However, these emissions would be intermittent and would dissipate rapidly from the source. In addition, these odors would only be present temporarily and would dissipate below any air quality concern. Therefore, future construction associated with Project implementation would not create objectionable odors affecting a substantial number of people, and this impact would be less than significant.

Operations
Residential land uses that would be accommodated by future Project implementation could result in the generation of odors, such as exhaust from landscaping equipment and from cooking. Residences are not considered potential generators of odors that could affect a substantial number of people. Therefore, impacts from potential odors generated from residential land uses associated with Project implementation would be less than significant.

3.1.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative air quality impact?
Finding: Same Impact as Approved Project (Significant and Unavoidable Cumulative Impact) Cumulative impacts related to air quality are based on the regional boundaries of the SoCAB. The Project itself is a planning document consisting of zoning code updates to facilitate future lower- and moderateincome development in the City. It does not, in and of itself, constitute a development project. Future residential projects resulting from Project implementation would have to undertake their own air quality studies and comply with all However, future activities related to the Project, in conjunction with the buildout of uses as provided in the General Plan Update over the planning horizon, would cumulatively contribute to a significant air quality impact. Therefore, even with incorporation of mitigation measures, this impact would remain cumulatively considerable.

3.1.2.4 Mitigation Measures
The following mitigation measures are required for the proposed project.

Mitigation Measure AQ-1. Project proponents of new development projects shall incorporate mitigation measures to reduce air pollutant emissions during construction activities. Mitigation measures shall be incorporated into all appropriate construction documents/plans (e.g., construction management plans) submitted to the City and shall be verified by the City’s Development Services 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

Division. Mitigation measures to reduce construction related emissions could include, but are not limited to:
• Requiring fugitive-dust control measures that exceed SCAQMD’s Rule 403, such as:
o Use of nontoxic soil stabilizers to reduce wind erosion. o Applying water every four house to active soil-disturbing activities. o Tarping and/or maintaining a minimum of 24 inches of freeboard on trucks hauling dirt, sand, soil, or other loose materials.
o Using construction equipment rated by the United States Environmental Protection Agency as having Tier 3 (model year 2006 or newer) or Tier 4 (model year 2008 or newer) emission limits, applicable for engines between 50 and 750 horsepower.
o Ensuring that construction equipment is properly serviced and maintained to the manufacturer’s standards.
o Limiting nonessential idling of construction equipment to no more than five consecutive minutes.
o Limiting onsite vehicle travel speeds on unpaved roads to 15 miles per hour. o Installing wheel washers for all existing trucks or wash off all trucks and equipment leaving the project area.

A list of Super-Compliant architectural coating manufacturers can be found on the SCAQMD’s website at http://www.aqmd.gov/docs/default-source/planning/ architectural-coatings/supercompliant-manf-list.pdf?sfvrsn=71.

Mitigation Measure AQ-2. Project proponents of new development projects shall incorporate mitigation measures to reduce air pollutant emissions during operational activities. Mitigation measures shall be included as part of the construction drawings for the project’s permit. Mitigation measures to reduce long-term emissions could include, but are not limited to the following:
• For site-specific development that requires refrigerated vehicles, the construction documents shall demonstrate an adequate number of electrical service connections at loading docks for plug-in of the anticipated number of refrigerated trailers to reduce idling time and emissions. • Applicants for manufacturing and light industrial uses shall consider energy storage and combined heat and power in appropriate applications to optimize renewable energy generation systems and avoid peak energy use.

3.2 ENERGY

3.2.1 Environmental Setting
Southern California Edison (SCE) is the provider of electrical services to most of the City and its SOI. Total electricity consumption in SCE’s service area, which spans much of southern California from Orange and Riverside Counties on the south to Santa Barbara County on the west to Mono County to the north, in gigawatt-hours (GWh) was 102,521 GWh in 2018 (City of Corona 2019). Sources of electricity sold by SCE in 2017 were:
• 32 percent renewable, consisting mostly of solar and wind • 8 percent large hydroelectric
• 20 percent natural gas
• 6 percent nuclear
• 34 percent unspecified sources
On April 4, 2001, the City Council passed Resolution No. 2001-25, which established a municipally owned electric utility. In August 2001, this electric utility, which is part of the Corona Department of Water and Power (DWP) [Corona DWP has since been renamed Corona Utilities Department], entered into an agreement with SCE to provide retail services as an electric services provider. Corona Utilities buys and sells power on behalf of the City’s municipal electric accounts and properties within specific service areas.

In 2018, the estimated existing electricity demand for residential developments in the City was 371,670,609 kWh (kilowatt-hours) per year, with the City and SOI having a total demand of 1,412,642,823 kWh per year (City of Corona 2019).

Southern California Gas Company (SoCalGas) provides natural gas services to the City and maintains transmission and distribution lines through the City and SOI. The service area of SoCalGas spans much of the southern half of California, from Imperial County in the southeast, to San Luis Obispo County in the northwest, to part of Fresno County in the north, and to Riverside County and most of San Bernardino County in the east. According to the General Plan Update EIR, existing natural gas demands in the City for residential developments is 19.4 million therms per year, and total natural gas demand for the City and its SOI was estimated at 43.9 million therms per year (City of Corona 2019).

3.2.1.1 Regulatory Framework
Federal
Energy Independence and Security Act of 2007
The Energy Independence and Security Act of 2007 (Public Law 110-140) seeks to provide the nation with greater energy independence and security by increasing the production of clean renewable fuels; improving vehicle fuel economy; and increasing the efficiency of products, buildings, and vehicles. It also seeks to improve the energy performance of the federal government. The Energy Independence and Security Act sets increased Corporate Average Fuel Economy Standards; the Renewable Fuel Standard; appliance energy efficiency standards; building energy efficiency standards; and accelerated research and 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-26
development tasks on renewable energy sources (e.g., solar energy, geothermal energy, and marine and hydrokinetic renewable energy technologies), carbon capture, and sequestration.

Federal Energy Regulatory Commission
The Federal Energy Regulatory Commission (FERC) is an independent agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC also reviews proposals to build liquefied natural gas terminals and interstate natural gas pipelines, and licenses hydropower projects. Licensing of hydroelectric facilities under FERC’s authority includes input from state and federal energy and power generation, environmental protection, fish and wildlife, and water quality agencies.

Federal Energy Conservation Policy Act
The National Energy Conservation Policy Act (42 United States Code Section 8201 et seq.) serves as the underlying authority for federal energy management goals and requirements and is the foundation of most federal energy requirements. The National Energy Conservation Policy Act also established fuel economy standards for on-road motor vehicles in the U.S. The National Highway Traffic Safety Administration (NHTSA) is responsible for establishing additional vehicle standards and for revising existing standards.

NHTSA and the USEPA are taking coordinated steps to enable the production of clean energy vehicles with improved fuel efficiency. NHTSA sets the Corporate Average Fuel Economy (I) levels, which, based on Obama-era regulations, would have required about 5 percent annual increases in fuel efficiency.

However, in March 2020, the Trump administration rolled back the standards, with the final rule increasing the stringency of I and carbon dioxide emission standards by 1.5 percent each year through 2026.

State
California Public Utilities Commission Requirements
The California Public Utilities Commission (CPUC) is a state agency created by a constitutional amendment to regulate privately-owned utilities providing telecommunications, electric, natural gas, water, railroad, rail transit, and passenger transportation services and in-state moving companies. CPUC is responsible for assuring that California utility customers have safe, reliable utility services at reasonable rates while protecting utility customers from fraud. CPUC regulates the planning and approval for the physical construction of electric generation, transmission, or distribution facilities and local distribution pipelines of natural gas.

California Integrated Energy Policy
SB 1389 requires the CEC to “conduct assessments and forecasts of all aspects of energy industry supply, production, transportation, delivery and distribution, demand, and prices. The Energy Commission shall use these assessments and forecasts to develop energy policies that conserve resources, protect the environment, ensure energy reliability, enhance the state’s economy, and protect public health and safety” (PRC Section 25301[a]). The CEC adopts an Integrated Energy Policy Report every two years and an update every other year.

AB 1493 – Clean Car Standards (Pavley)
AB 1493 was passed in 2002 and requires CARB to develop and implement regulations to reduce automobile and light truck GHG emissions, through mandating gradual reductions in global warming pollutants from cars and light trucks sold in California from 2009 through 2016. The average gram-per-mile reduction of GHG emissions from new California cars and light trucks is required to be about 30 percent in 2016 compared to model year 2004 vehicles.

CARB adopted the Advanced Clean Cars (ACC) program in 2012 in coordination with USEPA and NHTSA.

The ACC program combined the control of criteria pollutants and GHG emissions into a single coordinated set of requirements for model years 2015 through 2025. CARB adopted a new approach to passenger vehicles—cars and light trucks—by combining the control of smog-causing pollutants and GHG emissions into a single coordinated package of standards. The new approach also includes efforts to support and accelerate the numbers of plug-in hybrids and zero-emission vehicles in California. The new standard drops GHG emissions to 166 grams per mile, a reduction of 34 percent compared to 2016 levels, through 2025.

Warren-Alquist Energy Resources Conservation and Development Act Initially passed in 1974 and amended since, the Warren-Alquist Energy Resources Conservation and Development Act (Warren-Alquist Act) created the CEC, California’s primary energy and planning agency.

The seven responsibilities of CEC are: forecasting future energy needs, promoting energy efficiency and conservation through setting standards, supporting energy related research, developing renewable energy resources, advancing alternative and renewable transportation fuels and technologies, certifying thermal power plants 50 megawatts or larger, and planning for and directing state responses to energy emergencies. CEC regulates energy resources by encouraging and coordinating research into energy supply and demand problems to reduce the rate of growth of energy consumption. Additionally, the WarrenAlquist Act acknowledges the need for renewable energy resources and encourages CEC to explore renewable energy options that would be in line with environmental and public safety goals. (Warren-Alquist Act PRC section 25000 et seq.)
Renewable Portfolio Standard
SB 1078, 107, X1-2, and Executive Order S-14-08
The California Renewables Portfolio Standard (RPS) Program was stablished in 2002 under SB 1078 (Sher) and 107 (Simitian). The RPS program requires investor-owned utilities, electric service providers, and community choice aggregators to increase the use of eligible renewable energy resources to 33 percent of total procurement by 2020. Initially under the RPS, certain retail sellers of electricity were required to increase the amount of renewable energy each year by at least 1 percent in order to reach at least 20 percent by December 20, 2010. Executive Order (EO) S-14-08 was signed in November 2008, which expanded the state’s Renewable Energy Standard to 33 percent renewable power by 2020. This standard was adopted by the legislature in 2011 (SB X1-2). The California Public Utilities Commission is required to provide quarterly progress reports on progress toward RPS goals. This has accelerated the development of renewable energy projects throughout the State.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3-28
SB 350
SB 350 (de Leon), was signed into law September 2015. SB 350 establishes tiered increases to the RPS of 40 percent by 2024, 45 percent by 2027, and 50 percent by 2030. SB 350 also set a new goal to double the energy efficiency savings in electricity and natural gas through energy efficiency and conservation measures.

SB 100
On September 10, 2018, Governor Brown signed SB 100, which replaces the SB 350 requirement of 45 percent renewable energy by 2027 with the requirement of 50 percent by 2026 and also raises California’s RPS requirements for 2050 from 50 percent to 60 percent. SB 100 also establishes RPS requirements for publicly owned utilities that consist of 44 percent renewable energy by 2024, 50 percent by 2027, and 60 percent by 2030. Furthermore, the bull also establishes an overall state policy that eligible renewable energy resources and zero-carbon resources supply 100 percent of all retail sales of electricity to California end-use customers and 100 percent of electricity procured to serve all state agencies by December 31, 2045. Under the bill, the state cannot increase carbon emissions elsewhere in the western grid or allow resource shuffling to achieve the 100 percent carbon-free electricity target.

Title 24, Part 6, Energy Efficiency Standards
Energy conservation standards for new residential and non-residential buildings were adopted by the California Energy Resources Conservation and Development Commission (now the CEC) in June 1977 and most recently revised in 2016 (24 CCR Part 6). Title 24 requires the design of building shells and building components to conserve energy. The standards are updated periodically to allow for consideration and possible incorporation of new energy efficiency technologies and methods. On June 10, 2015, the CEC adopted the 2016 Building Energy Efficiency Standards, which went into effect on January 1, 2017. The 2019 Building Energy Efficiency Standards, which were recently adopted on May 9, 2018, go into effect starting January 1, 2020.

The 2016 Standards improve upon the previous 2013 Standards for new construction of and additions and alterations to residential and nonresidential buildings. Under the 2016 Standards, residential and nonresidential buildings are generally 28 and 5 percent more energy efficient than the 2013 Standards, respectively. Although the 2016 standards do not achieve zero net energy, they get very close to the state’s goal and take important steps toward changing residential building practices in California.

The 2019 standards move toward cutting energy use in new homes by more than 50 percent and will require installation of solar photovoltaic systems for single-family homes and multifamily buildings of three stories and less. The 2019 standards focus on four key areas: 1) smart residential photovoltaic systems; 2) updated thermal envelope standards (preventing heat transfer from the interior to exterior and vice versa); 3) residential and nonresidential ventilation requirements; 4) and nonresidential lighting requirements. Under the 2019 standards, nonresidential buildings will be 30 percent more energy efficient compared to the 2016 standards, and single-family homes will be 7 percent more energy efficient. When accounting for the electricity generated by the solar photovoltaic system, single-family homes would use 53 percent less energy compared to homes built to the 2016 standards.

Title 24, Part 11, Green Building Standards
On July 17, 2008, the California Building Standards Commission adopted the nation’s first green building standards. The California Green Building Standards Code (24 CCR, Part 11, known as “CALGreen”) was adopted as part of the California Building Standards Code. It includes mandatory requirements for new residential and nonresidential buildings throughout California. CALGreen is intended to (1) reduce GHG emissions from buildings; (2) promote environmentally responsible, cost-effective, healthier places to live and work; (3) reduce energy and water consumption; and (4) respond to the directives by the Governor.

The mandatory provisions of the California Green Building Code Standards became effective January 1, 2011 and were last updated in 2016. The 2016 Standards became effective on January 1, 2017. On October 3, 2018, the CEC adopted the voluntary standards of the 2019 CALGreen, which become effective January 1, 2020.

Overall, the code is established to reduce construction waste, make buildings more efficient in the use of materials and energy, and reduce environmental impact during and after construction. CALGreen contains requirements for construction site selection; storm water control during construction; construction waste reduction; indoor water use reduction; material selection; natural resource conservation; site irrigation conservation; and more. The code provides for design options allowing the designer to determine how best to achieve compliance for a given site or building condition. The code also requires building commissioning, which is a process for verifying that all building systems (e.g., heating and cooling equipment and lighting systems) are functioning at their maximum efficiency.

Local
City of Corona Climate Action Plan
The City of Corona’s 2019 Climate Action Plan (CAP) Update provides direction for the reduction of GHG emissions from sources under the City’s jurisdiction in coordination with the City’s land use decisions from the General Plan. The 2019 CAP provides measures to meet the goal of reducing community GHG emissions to a level 20 percent below projected business-as-usual emissions for 2020. Furthermore, the 2019 CAP aims to meet the goals set forth in EO S-03-05 to reduce GHG emissions to a level 80 percent below 1990 levels by 2050.

To meet the established 2020 Reduction Target, the current CAP includes various reduction measures across several sectors that include transportation, energy, water, solid waste, and agriculture. The reduction measures encompass both state- and local-based measures. Identified state-based measures related to energy include compliance with the Building Energy Efficiency Standards and CALGreen and utilities meeting the RPS. The 2019 CAP also includes energy-related local-based measures, which are measures the City can implement that are beyond statewide measures. Other energy-related local measures include supporting energy efficiency and renewable energy retrofits for existing homes and commercial buildings.

The 2019 CAP also includes measures that support increasing the Incorporation of renewable energy systems into new residential and non-residential development projects. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and energy resources discussed in this section:

Policy ER-12.14: Reduce energy consumed by commercial and residential uses by requiring the use and installation of energy conservation features in all new construction projects and wherever feasible, retrofitting existing and redevelopment projects.

Policy ER-13.2: Encourage the maximum feasible energy efficiency in site design, building orientation, landscaping, and utilities/infrastructure for all development and redevelopment projects (residential, commercial, industrial, and public agency) to support GHG emissions reductions.

Policy IU-71: Require that new development is approved contingent upon its ability to be served with adequate natural gas, energy facilities, and other critical infrastructure.

3.2.2 Impact Discussion

3.2.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to energy are significant. Would the Project:
• Result in potentially significant environmental impacts due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? The following issues were determined to have no impact or a less than significant impact during the Initial Study and NOP Scoping process. These issues were sufficiently analyzed in the Initial Study and are not discussed further in this section. Would the Project:
• Conflict with or obstruct a state or local plan for renewable energy and energy efficiency?

3.2.2.2 Project Impacts
Would the Project result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during Project construction or operation? Finding: Same Impact as Approved Project (Less than Significant Impact) Construction
Construction of the proposed project would occur over an extended period consistent with the General Plan Horizon Year of 2040 or longer. Individual residential projects developed in accordance with the proposed project would require the use of both onroad (employee vehicles, delivery trucks, etc.) and offroad construction equipment (graders, crawler tractors, etc.) in addition to electric-powered hand tools (power drills, table saws, etc.)

During construction, individual projects would comply with General Plan EIR Mitigation Measure AQ-1 which is aimed at reducing air pollution and includes measures such as minimizing idling of construction offroad equipment and maintaining all equipment in accordance with manufacturer standards. Such measures would also minimize the wasteful consumption of energy resources during construction. The construction of future residential development resulting from Project implementation would result in less than significant impacts.

Operations
Implementation of the proposed project would result in an increase of 5.6 percent new residential housing units that were unaccounted for in the General Plan Update that would create additional demand for electricity, natural gas, and motor vehicle fuels. Each energy source is discussed separately below.

According to the General Plan Update EIR the existing electricity use within the City and SOI would total 1,412,642,823 kWh annually. Electrical service to the City and SOI would be provided by SCE and Corona DWP through connections to existing off-site electrical lines and new on-site infrastructure.

Future development resulting from Project implementation is anticipated to add 9,990 new residents to the City of Corona through the 2040 Horizon Year. Table 3.2-1 provides an estimate of the increase in electricity consumption resulting from Project implementation. Project implementation is anticipated to result in a total demand of 436,201,062 kilowatt-hours (kWh).

Natural Gas
The General Plan Update EIR provided an estimate of existing natural gas usage within the City and SOI of 43,945,421 therms for all uses annually. Natural gas service to the City and SOI would be provided by the Southern California Gas Company (SoCalGas). Project implementation is anticipated to add 9,990 new residents to the City of Corona through the 2040 Horizon Year. Table 3.2-2 provides an estimate of the increase in natural gas consumption from project implementation.

Transportation Fuels
Project implementation resulting in future residential development would consume transportation energy (e.g., gasoline, diesel, compressed natural gas (CNG), and electricity) during operations form the use of motor vehicles. As shown in Table 3.2-3, Project implementation would result in a decrease of 16,288,762 gallons of gasoline, an increase of 79,964 gallons of diesel, an increase of 671,099 gallons of CNG, and an increase of 41,192,144 kWh of electricity relative to the existing baseline. ,-- -

Source: City of Corona 2019 General Plan Update Table 5.6-6 As shown in the table above, VMT and fuel usage would generally increase from future implementation of the Project; however, the fuel efficiency of gasoline- and diesel-powered vehicles under year 2040 conditions would improve compared to baseline year 2018. VMT associated with electric vehicles (EV), and thus electricity usage, would also increase under future Project implementation when compared to existing baseline. It is also anticipated that EVs will improve in energy efficiency. Consistent with regulatory measures aimed at increasing the supply of electricity from renewable sources, it is anticipated that a greater share of the electricity used to power EVs will be from renewable sources.

Although future residential development resulting from Project implementation would demand additional transportation fuels in certain categories, others would decrease or become energy efficient. The use of transportation fuels would not be inefficient or wasteful. Impacts would be less than significant.

3.2.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative energy impact?
Finding: Same Impact as Approved Project (Less than Significant Impact) Cumulative impacts related to energy are based on the regional boundaries of the City and County, as well as the extent of service providers and their territories. The cumulative effects of Project implementation related to the wasteful, inefficient, or unnecessary consumption of energy and conflicting with energy plans and standards would be the same as discussed above. Energy impacts are localized and would not combine with the similar effects of other projects. The Project itself is a planning document consisting of zoning code updates to facilitate future lower- and moderate-income development in the City. It does not, in and of itself, constitute a development project. Future activities related to Project implementation, in conjunction with the buildout of uses as provided in the General Plan Update over the planning horizon, would cumulatively contribute to the increase in demand for energy resources. Each implementing development project would have to undertake site-specific evaluations and their own discretionary permits with respect to their potential energy consumption, and they would be subject to all applicable regulations and requirements related to energy efficiency, as described above. Therefore, future Project implementation would not result in a cumulatively considerable contribution to a significant cumulative energy impact, and this impact would be less than significant. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3.3 GREENHOUSE GAS EMISSIONS

3.3.1 Environmental Setting

3.3.1.1 Greenhouse Gases
GHGs and climate change are cumulative global issues. CARB and the Cal EPA regulate GHG emissions within the State of California and the U.S., respectively. While the CARB has the primary regulatory responsibility within California for GHG emissions, local agencies can also adopt policies for GHG emission reductions.

Many chemical compounds in the earth’s atmosphere act as GHGs, as they absorb and emit radiation within the thermal infrared range. When radiation from the sun reaches the Earth’s surface, some of it is reflected back into the atmosphere as infrared radiation (heat). GHGs absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy from the sun to the Earth’s surface should be approximately equal to the amount of energy radiated back into space, leaving the temperature of the earth’s surface roughly constant. Many gases exhibit these “greenhouse” properties. Some of them occur in nature (water vapor, carbon dioxide [CO2], methane [CH4], and nitrous oxide [N2O]), while others are exclusively human-made (like gases used for aerosols).

The principal climate change gases resulting from human activity that enter and accumulate in the atmosphere are listed below:
• Carbon Dioxide. CO2 enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and chemical reactions (e.g., the manufacture of cement). CO2 is also removed from the atmosphere (or “sequestered”) when it is absorbed by plants as part of the biological carbon cycle.
• Methane. CH4 is emitted during the production and transport of coal, natural gas, and oil. CH4 emissions also result from livestock and agricultural practices and the decay of organic waste in municipal solid waste landfills, raising livestock, natural gas and petroleum systems, stationary and mobile combustion, and wastewater treatment.
• Nitrous Oxide. N2O is emitted during agricultural and industrial activities as well as during combustion of fossil fuels and solid waste. N2O emissions from motor vehicles generally occur directly from operation of vehicles.
• Hydrofluorocarbons. HFCs are one of several high global warming potential (GWP) gases that are not naturally occurring and are generated from industrial processes. HFC (refrigerant) emissions from vehicle air conditioning systems occur due to leakage, losses during recharging, or release from scrapping vehicles at end of their useful life. • Perfluorocarbons. PFCs are another high GWP gas that are not naturally occurring and are generated in a variety of industrial processes.

3-36
• Sulfur Hexafluoride. SF6 is another high GWP gas that is not naturally occurring and is generated in a variety of industrial processes.

3.3.1.2 Sources of Greenhouse Gas Emissions
On a global scale, GHG emissions are predominantly associated with activities related to energy production; changes in land use, such as deforestation and land clearing; industrial sources; agricultural activities; transportation; waste and wastewater generation; and commercial and residential land uses.

World-wide, energy production including the burning of coal, natural gas, and oil for electricity and heat is the largest single source of global GHG emissions.

In 2019, GHG emissions within California totaled 418.1 million metric tons (MMT) of carbon dioxide equivalent (CO2e). Within California, the transportation sector is the largest contributor, accounting for approximately 41 percent of the total statewide GHG emissions. Emissions associated with industrial uses are the second largest contributor, totaling roughly 24 percent. Electricity generation totaled roughly 14 percent. Residential, commercial, and agricultural/forestry made up the approximately 8 percent, 6 percent, and 8 percent of the remaining GHG emissions (CARB 2021).

3.3.1.3 Potential Environmental Impacts
There are uncertainties as to exactly what the climate changes will be in various local areas of the earth.

There are also uncertainties associated with the magnitude and timing of other consequences of a warmer planet: sea level rise, spread of certain diseases out of their usual geographic range, the effect on agricultural production, water supply, sustainability of ecosystems, increased strength and frequency of storms, extreme heat events, increased air pollution episodes, and the consequence of these effects on the economy.

Within California, climate changes would likely alter the ecological characteristics of many ecosystems throughout the state. Such alterations would likely include increases in surface temperatures and changes in the form, timing, and intensity of precipitation. For instance, historical records are depicting an increasing trend toward earlier snowmelt in the Sierra Nevada. This snowpack is a principal supply of water for the state, providing roughly 50 percent of state’s annual runoff. If this trend continues, some areas of the state may experience an increased danger of floods during the winter months and possible exhaustion of the snowpack during spring and summer months. An earlier snowmelt would also impact the state’s energy resources. An early exhaustion of the Sierra snowpack may force electricity producers to switch to more costly or non-renewable forms of electricity generation during spring and summer months. A changing climate may also impact agricultural crop yields, coastal structures, and biodiversity. As a result, resultant changes in climate will likely have detrimental effects on some of California’s largest industries, including agriculture, wine, tourism, skiing, recreational and commercial fishing, and forestry.

3.3.1.4 General Plan Update EIR
An emissions inventory of the City of Corona and SOI was conducted for the General Plan Update EIR for the existing residential, institutional, commercial, office, and industrial uses identified on Figure 3-4, Existing 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation

Land Use in the General Plan Update EIR. GHG emissions generated in the City and SOI were estimated using EMFAC2017, OFFROAD2017, and data provided by SCE (electricity), SoCalGas (natural gas), and the City of Corona (electricity and water use). Emissions in the City and SOI come from the following sources:
• Transportation: Emissions from vehicle trips beginning and ending in the City and SOI boundaries and from external/internal vehicle trips (i.e., trips that either begin or end in the City and SOI). • Energy: Emissions generated from purchased electricity and natural gas consumption used for cooking and heating in the City and SOI.
• Solid Waste Disposal: Indirect emissions from waste generated in the City and SOI. • Water/Wastewater: Emissions from electricity used to supply, treat, and distribute water based on the overall water demand and wastewater generation in the City and SOI. • Area Sources: Emissions generated from light commercial equipment, agricultural, and construction equipment use in the City and SOI.

3.3.1.5 Regulatory Framework
State
In the absence of federal regulations, control of GHGs is generally regulated at the state level and is typically approached by setting emission reduction targets for existing sources of GHGs, setting policies to promote renewable energy and increase energy efficiency, and developing statewide action plans.

California has adopted statewide legislation addressing various aspects of climate change and GHG emissions mitigation. Much of this legislation establishes a broad framework for the state’s long-term GHG reduction and climate change adaptation program. The governor has also issued several executive orders (EOs) related to the state’s evolving climate change policy.

Current State of California guidance and goals for reduction in GHG emissions are generally embodied in EO S-03-05 and B-30-15, AB 32, SB 32, and SB 375.

Executive Order S-03-05
On June 1, 2005, former California Governor Arnold Schwarzenegger announced EO S‐3‐05, which announced the following reduction targets for GHG emissions:
• By 2010, reduce GHG emissions to 2000 levels.
• By 2020, reduce GHG emissions to 1990 levels.
• By 2050, reduce GHG emissions to 80 percent below 1990 levels. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-38
The 2050 reduction goal represents what some scientists believe is necessary to reach levels that would stabilize the climate. The 2020 goal was established to be a mid‐term target. Because this is an EO, the goals are not legally enforceable for local governments or the private sector.

Executive Order B-30-15
On April 29, 2015, Governor Edmund G. Brown Jr. issued EO B-30-15 to establish a California GHG reduction target of 40 percent below 1990 levels by 2030. The Governor’s EO aligns California’s GHG reduction targets with those of leading international governments ahead of the United Nations Climate Change Conference in Paris in late 2015. The EO sets a new interim statewide GHG emission reduction target to reduce GHG emissions to 40 percent below 1990 levels by 2030 in order to ensure that California meets its target of reducing GHG emissions to 80 percent below 1990 levels by 2050 and directs CARB to update the Climate Change Scoping Plan to express the 2030 target in terms of MMTCO2e. The EO also requires the state’s climate adaptation plan to be updated every 3 years and for the state to continue its climate change research program, among other provisions. As with EO S‐3‐05, this EO is not legally enforceable against local governments and the private sector. Legislation that would update AB 32 to provide post‐2020 targets was signed by the Governor in 2016. SB 32 includes a 2030 mandate matching the requirements of the EO.

Assembly Bill 32
The California State Legislature enacted AB 32, the California Global Warming Solutions Act of 2006.

Current State of California guidance and goals for reductions in GHG emissions are generally embodied in the Global Warming Solutions Act. AB 32 was passed by the California state legislature on August 31, 2006, to place the state on a course toward reducing its contribution of GHG emissions. AB 32 follows the 2020 tier of emissions reduction targets established in EO S-03-05.

SB 32
SB 32 was signed into law on September 8, 2016. SB 32 gives CARB the statutory responsibility to include the 2030 target previously contained in EO B‐30‐15 in the 2017 Scoping Plan Update. SB 32 states that “In adopting rules and regulations to achieve the maximum technologically feasible and cost‐effective greenhouse gas emissions reductions authorized by this division, the state [air resources] board shall ensure that statewide greenhouse gas emissions are reduced to at least 40 percent below the statewide greenhouse gas emissions limit no later than December 31, 2030.” Climate Change Scoping Plan
In December 2008, CARB approved the AB 32 Scoping Plan outlining the state’s strategy to achieve the 2020 GHG emissions limit. The Scoping Plan estimates a reduction of 174 MMTCO2e (about 191 million U.S. tons) from the transportation, energy, agriculture, forestry, and high climate-change-potential sectors, and proposes a comprehensive set of actions designed to reduce overall GHG emissions in California, improve the environment, reduce dependence on oil, diversify California’s energy sources, save energy, create new jobs, and enhance public health. The Scoping Plan must be updated every 5 years to evaluate the implementation of AB 32 policies to ensure that California is on track to achieve the 2020 GHG reduction 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-39
goal. The First Update to the Climate Change Scoping Plan was approved by the CARB on May 22, 2014.

In 2016, the State Legislature passed SB 32, which codified a 2030 GHG emissions reduction target of 40 percent below 1990 levels. With SB 32, the State Legislature passed companion legislation AB 197, which provides additional direction for developing the Scoping Plan. On December 14, 2017, the CARB approved the Second Update to the Climate Change Scoping Plan, the 2017 Climate Change Scoping Plan: The Strategy for Achieving California’s 2030 Greenhouse Gas Target. The 2017 Scoping Plan identified key sectors of the implementation strategy, which includes improvements in low carbon energy, industry, transportation sustainability, natural and working lands, waste management, and water. Through a combination of data synthesis and modeling, CARB determined that the target statewide 2030 emissions limit is 260 MMTCO2e, and that further commitments will need to be made to achieve an additional reduction of 50 MMTCO2e beyond current policies and programs. Key elements of the 2017 Update include a proposed 20 percent reduction in GHG emissions from refineries and an expansion of the Cap-and-Trade program to meet the aggressive 2030 GHG emissions goal.

SB 375
In 2008, SB 375, the Sustainable Communities and Climate Protection Act, was adopted to connect the GHG emissions reductions targets established in the 2008 Scoping Plan for the transportation sector to local land use decisions that affect travel behavior. Its intent is to reduce GHG emissions from light-duty trucks and automobiles (excludes emissions associated with goods movement) by aligning regional longrange transportation plans, investments, and housing allocations to local land use planning to reduce VMT and vehicle trips. Specifically, SB 375 required CARB to establish GHG emissions reduction targets for each of the 18 metropolitan planning organizations (MPOs). The Southern California Association of Governments (SCAG) is the MPO for the Southern California region, which includes the counties of Los Angeles, Orange, San Bernardino, Riverside, Ventura, and Imperial. Pursuant to the recommendations of the Regional Transportation Advisory Committee, CARB adopted per capita reduction targets for each of the MPOs rather than a total magnitude reduction target.

SB 1078, 107, X1-2, and Executive Order S-14-08
A major component of California’s Renewable Energy Program is the RPS established under SB 1078 (Sher) and 107 (Simitian). Under the RPS, certain retail sellers of electricity were required to increase the amount of renewable energy each year by at least 1 percent in order to reach at least 20 percent by December 30, 2010. EO S-14-08 was signed in November 2008, which expanded the state’s Renewable Energy Standard to 33 percent renewable power by 2020. This standard was adopted by the legislature in 2011 (SBX1- 2). Renewable sources of electricity include wind, small hydropower, solar, geothermal, biomass, and biogas. The increase in renewable sources for electricity production will decrease indirect GHG emissions from development projects because electricity production from renewable sources is generally considered carbon neutral.

SB 350
SB 350 (de Leon) was signed into law September 2015. SB 350 establishes tiered increases to the RPS of 40 percent by 2024, 45 percent by 2027, and 50 percent by 2030. SB 350 also set a new goal to double 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-40
the energy efficiency savings in electricity and natural gas through energy efficiency and conservation measures.

SB 100
On September 10, 2018, Governor Brown signed SB 100, which replaces the SB 350 requirement of 45 percent renewable energy by 2027 with the requirement of 50 percent by 2026 and also raises California’s RPS requirements for 2050 from 50 percent to 60 percent. SB 100 also establishes RPS requirements for publicly owned utilities that consist of 44 percent renewable energy by 2024, 52 percent by 2027, and 60 percent by 2030. Furthermore, the bill also establishes an overall state policy that eligible renewable energy resources and zero-carbon resources supply 100 percent of all retail sales of electricity to California enduse customers and 100 percent of electricity procured to serve all state agencies by December 31, 2045.

Under the bill, the state cannot increase carbon emissions elsewhere in the western grid or allow resource shuffling to achieve the 100 percent carbon-free electricity target.

Executive Order B-55-18
EO B‐55‐18 issued by Governor Brown on September 10, 2018, establishes a new statewide goal to achieve carbon neutrality as soon as possible, but no later than 2045, and to achieve and maintain net negative emissions thereafter. The EO directs CARB to work with relevant state agencies to develop a framework for implementation and accounting that tracks progress toward this goal.

California Energy Code
Compliance with the California Energy Code (Title 24, Part 6, of the CCR, California’s Energy Efficiency Standards) and Title 20, Public Utilities and Energy, standards must occur for all new buildings constructed in California. These efficiency standards apply to new construction of both residential and nonresidential (i.e., maintenance buildings and pump station buildings associated with the Program) buildings, and they regulate energy consumed for heating, cooling, ventilation, water heating, and lighting. The building efficiency standards are enforced through the local building permit processes, and local government agencies may adopt and enforce energy standards for new buildings provided that these standards meet or exceed those provided in the Title 24 guidelines.

Local
City of Corona Climate Action Plan
The City of Corona’s 2019 CAP Update provides direction for the reduction of GHG emissions from sources under the City’s jurisdiction in coordination with the City’s land use decisions from the General Plan. The 2019 CAP provides measures to meet the goal of reducing community GHG emissions to a level 20 percent below projected business-as-usual emissions for 2020. Furthermore, the 2019 CAP aims to meet the goals set forth in EO S-03-05 to reduce GHG emissions to a level 80 percent below 1990 levels by 2050.

To meet the established 2020 Reduction Target, the current CAP includes various reduction measures across several sectors that include transportation, energy, water, solid waste, and agriculture. The reduction measures encompass both state- and local-based measures. Identified state-based measures related to 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

energy include compliance with the Building Energy Efficiency Standards and CALGreen and utilities meeting the RPS. The 2019 CAP also includes energy-related local-based measures, which are measures the City can implement that are beyond statewide measures. Other energy-related local measures include supporting energy efficiency and renewable energy retrofits for existing homes and commercial buildings.

The 2019 CAP also includes measures that support increasing the incorporation of renewable energy systems into new residential and non-residential development projects.

City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and greenhouse gas discussed in this section:

Policy ER-12.2: Continue to cooperate with the SCAQMD and other local authorities in the air basin, in implementing air emission reduction programs and techniques.

3.3.2 Impact Discussion

3.3.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to greenhouse gas emissions are significant. Would the Project:
• Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
• Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
SCAQMD has adopted a significance threshold of 10,000 MTCO2e per year for permitted (stationary) sources of GHG emissions for which SCAQMD is the designated lead agency. To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, SCAQMD convened a GHG CEQA Significance Threshold Working Group (Working Group). SCAQMD identified a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency, however, the following tiered approach has not been formally adopted by SCAQMD. • Tier 1. If a project is exempt from CEQA, project-level and cumulative GHG emissions are less than significant.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-42
• Tier 2. If the project complies with a GHG emissions reduction plan or mitigation program that avoids or substantially reduces GHG emissions in the project’s geographic area (e.g., city or county), project-level and cumulative GHG emissions are less than significant. • Tier 3. If GHG emissions are less than the screening-level threshold, project-level and cumulative GHG emissions are less than significant.

For projects that are not exempt or where no qualifying GHG reduction plans are directly applicable, SCAQMD requires an assessment of GHG emissions. Project-related GHG emissions include onroad transportation, energy use, water use, wastewater generation, solid waste disposal, area sources, off-road emissions, and construction activities. The SCAQMD Working Group identified that because construction activities would result in a “one-time” net increase in GHG emissions, construction activities should be amortized into the operational phase GHG emissions inventory based on the service life of a building. For buildings in general, it is reasonable to look at a 30-year time frame, since this is a typical interval before a new building requires the first major renovation.

The SCAQMD identified a screening-level threshold of 3,000 MTCO2e annually for all land use types. This interim bright-line screening-level criteria are based on a review of the Governor’s Office of Planning and Research database of CEQA projects. Based on their review of 711 CEQA projects, 90 percent of CEQA projects would exceed the bright-line threshold. Therefore, projects that do not exceed the bright-line threshold would have a nominal, and therefore, less than cumulatively considerable impact on GHG emissions. Between the three identified thresholds, SCAQMD recommends use of the 3,000 MTCO2e interim bright-line screening-level criterion for all project types (SCAQMD 2010b).
• Tier 4. If emissions exceed the screening threshold, a more detailed review of the project’s GHG emissions is warranted.

SCAQMD has identified an efficiency target for projects that exceed the bright-line threshold: a 2020 efficiency target of 4.8 MTCO2e per year per service population (MTCO2e/year/SP) for project-level analyses and 6.6 MTCO2e/year/SP for plan-level projects (e.g., general plans). Service population is generally defined as the sum of residential and employment population of a project. The per capita efficiency targets are based on the AB 32 GHG reduction target and 2020 GHG emissions inventory prepared for CARB’s 2008 Scoping Plan.

For purposes of this analysis, the bright-line threshold of 3,000 MTCO2e/year is utilized to determine the project impact for horizon year 2040. In addition, the post-2020 reduction target and goal set by SB 32 and EO S-03-05, respectively, are also utilized to determine project significance for year 2030 and year 2050. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

Finding: Same Impact as Approved Project (Significant and Unavoidable Impact) Buildout of the proposed project would result in GHG emissions over the Project implementation horizon consistent with the General Plan of 2040 or greater. The proposed Project would implement zoning changes that would permit future additional dwelling units and population to the current growth projections beyond what was anticipated from the 2019 General Plan Update. Table 3.3-1 provides a summary of the proposed Project’s GHG emissions. As shown, Project implementation would result in a decrease 18,338 metric tons of carbon dioxide equivalent (MTCO2e) from existing conditions and would not exceed the 3,000 MTCO2e SCAQMD bright-line screening threshold. In addition, while implementation of the proposed Project will result in an increase of the service population by 80,444 persons (a 29 percent increase), emissions per person would decrease compared to existing baseline. Emissions per service population would decrease to 3.4 MTCO2e per service population (MTCO2e /SP) in horizon year 2040 from 4.5 MTCO2e/SP for the existing baseline year. Accordingly, implementation of the Project would result in less than significant GHG emissions impacts as it pertains to year 2040.

Consistency with SB 32 and Executive Order S-03-05 GHG Reduction Targets Implementation of the proposed Project would not generate an increase in GHG emissions from the CEQA baseline in the 2040 horizon year forecast. This analysis also considers the potential for the Project to conflict with the GHG reduction goals established under SB 32 and EO S-03-05, which require a reduction in statewide GHG emissions from existing conditions to achieve a 40 percent reduction in GHG emissions by 2030 and an 80 percent reduction in GHG emissions by 2050, respectively.

SB 32 Reduction Target
The City of Corona’s CAP indicates that its implementation would result in the City meeting the established GHG reduction target for year 2030. While future residential development resulting from Project implementation would result in a slight increase in the population and number of dwelling units, the same strategies in the CAP would apply.

Based on the overall statewide reduction target set under SB 32, the proposed CAP set a year 2030 reduction target of 890,378 MTCO2e (49 percent below 2008 levels) for the City. Per the proposed CAP, with implementation of the local reduction strategies in addition to state and federal reductions, the City’s community-wide inventory projected for year 2030 is 566,275 MTCO2e, which would provide an ample buffer for the growth associated with Project implementation to still meet the established year 2030 target (see Table 10, Community Emissions and Targets Comparison, of the proposed CAP). Therefore, future residential development resulting from Project implementation would result in less than significant GHG emissions impacts as it pertains to meeting the interim year 2030 reduction target.

Executive Order S-03-05 GHG Reduction Targets
Future implementation of the proposed Project would result in an overall net decrease in emissions in horizon year 2040 compared to existing baseline and is also projected to meet the year 2040 GHG emissions reduction target set in the proposed CAP. The City is also projected to meet the year 2030 GHG emissions reduction target even under the growth scenario associated with Project implementation. These two metrics provide an indication that the City would make progress in meeting the long-term year 2050 reduction goal of EO S-03-05. However, the CAP does not include any reduction strategies to meet the long-term 2050 reduction goal. Reduction strategies to meet the long-term 2050 GHG reduction goal in addition to establishment of a 2050 reduction target would be included in the planned future updates to the CAP. Therefore, like the General Plan Update, GHG emissions impacts related to future residential projects resulting from Project implementation are considered potentially significant in regard to meeting the longterm year 2050 reduction goal.

Conclusion
Implementation of the proposed Project would result in a reduction in GHG emissions in horizon year 2040 from existing baseline and is projected to meet the GHG reduction target established under SB 32; however, it may not meet the long-term GHG reduction goal under EO S-03-05. Accordingly, this is a potentially significant impact. The City would continue to implement General Plan EIR Mitigation Measure GHG-1, which requires the City to track and monitor the City’s GHG emissions and update the CAP every five years. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-45
However, the General Plan Update EIR identified that at this time there is no plan past 2030 that achieves the long-term GHG reduction goal established under EO S-03-05, and there are currently no additional statewide measures available to help the City meet the goal. Therefore, impacts related to future Project implementation would continue to be significant and unavoidable even with the continued incorporation of General Plan Update EIR Mitigation Measure GHG-1, as noted in the General Plan Update EIR.

Would the Project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
Finding: Same Impact as Approved Project (No Impact)
Project implementation would have a significant impact with respect to GHG emissions and global climate change if it would substantially conflict with the provisions of Section 15064.4(b) of the CEQA Guidelines.

Pursuant to Appendix G of the CEQA Guidelines, a significant GHG impact is identified if the project could conflict with applicable GHG reduction plans, policies, or regulations. Development projects would be subject to complying with SB 32, SCAG’s RTP/SCS, and the City’s CAP. SB 32 is a statewide reduction goal aimed at reducing emissions to 40% below 1990 levels by 2030. CARB’s 2017 Scoping Plan sets a framework for the State to meet the reduction targets of SB 32.

Consistency with the Final 2017 Scoping Plan Update
The CARB Scoping Plan is applicable to state agencies but is not directly applicable to cities/counties and individual projects (i.e., the Scoping Plan does not require the City to adopt policies, programs, or regulations to reduce GHG emissions). However, new regulations adopted by the state agencies outlined in the Scoping Plan result in GHG emissions reductions at the local level.

CARB issued the Final 2017 Scoping Plan Update in November 2017, and it establishes emissions reduction strategies necessary to meet SB 32’s 2030 reduction goals. CARB has released the Draft 2022 Scoping Plan. At the time this assessment was prepared, the Draft 2022 Scoping Plan had not been approved and therefore, consistency with the 2017 Scoping Plan was used for this analysis.

As shown in Table 3.3-2, the proposed project would be consistent with the 2017 Scoping Plan.

Post-2020 Cap-and-Trade Program Consistent. The Cap-and-Trade Program covers the GHG emissions associated with electricity
consumed in California, whether generated in-state
or imported. Therefore, GHG emissions associated
with CEQA projects’ electricity usage are covered by
the Cap-and-Trade Program. The Cap-and-Trade
Program also covers fuel suppliers (natural gas and
propane fuel providers and transportation fuel
providers) to address emissions from such fuels and
from combustion of other fossil fuels not directly
covered at large sources in the program’s first
compliance period.

Source of Measures: CARB, 2017
Source of Consistency Determination: Stantec Consulting Services Inc, 2022.

Based on this evaluation, this analysis finds that Project implementation would be consistent with all feasible and applicable strategies recommended in the 2017 Scoping Plan Update.

SCAG’s 2020 – 2045 Regional Transportation Plan/Sustainable Communities Strategy On September 3, 2020, SCAG’s Regional Council unanimously voted to approve and fully adopt Connect SoCal (2020–2045 RTP/SCS), and the addendum to the Connect SoCal Program Environmental Impact Report.

Connect SoCal is a long-range visioning plan that builds upon and expands land use and transportation strategies established over several planning cycles to increase mobility options and achieve a more sustainable growth pattern. It charts a path toward a more mobile, sustainable and prosperous region by making connections between transportation networks, between planning strategies and between the people whose collaboration can improve the quality of life for Southern Californians.

Table 5.7-7 in the 2019 General Plan Update EIR showed that the General Plan Update would be consistent with applicable RTP/SCS Transportation-Land Use Strategies from the 2016-2040 RTP/SCS. The 2020- 2045 RTP/SCS builds upon those same strategies. The proposed Project is the implementation of the General Plan and would likewise be consistent with the RTP/SCS. Furthermore, the housing development intensification on identified candidate parcels would help preserve land resources by developing within the City boundaries and potentially reduce VMT through denser development. This would be consistent with the 2020-2045 RTP/SCS. Accordingly, future residential development resulting from Project implementation would not conflict with the strategies outlined in the 2020-2045 RTP/SCS, and there would be no impact.

City of Corona Climate Action Plan
As discussed in Impact GHG-1, the City of Corona’s CAP indicates that the City will achieve the 2030 target with an ample buffer for the growth associated with future residential development resulting from Project J

implementation to still meet the established year 2030 target (see Table 10, Community Emissions and Targets Comparison, of the proposed CAP). Furthermore, individual implementing residential projects consistent with the proposed Project would be required to undergo screening consistent with the CAP. New residential development projects are required to complete Table 1: Screening Table for GHG Reduction Measures for Residential Development to demonstrate consistency with CAP measures. Projects that achieve 100 points from the screening table would be determined to be consistent with the CAP and less than significant. Residential projects not achieving the 100 points would require further analysis to determine significance of GHG impacts.

Through the application of the screening table for Residential Developments, the Project implementation would be consistent with the CAP. Therefore, future residential development resulting from Project implementation would not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases, and there would be no impact.

3.3.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative greenhouse gas emission impact?
Finding: Same Impact as Approved Project (Significant and Unavoidable Impact) GHG impacts are a cumulative impact. On their own, GHG emissions from one project cannot result in changes in climatic conditions; therefore, the emissions from one project must be considered in the context of their contribution to cumulative global emissions, which is a significant cumulative impact. As discussed above, Project would be consistent with the City’s CAP and other regulations related to the reduction of GHG emissions. However, the General Plan Update EIR identified that at this time there is no plan past 2030 that achieves the long-term GHG reduction goal established under EO S-03-05, and there are currently no additional statewide measures available to help the City meet the goal. As such, this impact was conservatively determined to be significant and unavoidable, even though it would be less than significant with respect to its SB 32 reduction targets and with respect to year 2040. Future residential development resulting from Project implementation would be consistent with best practices for reducing GHGs through the incorporation of greater energy efficiency, higher densities, and locating future residential development predominantly in a HQTA. Other projects in the region and the State would also have to show consistency with local and State GHG reduction plans and comply with the Title 24 and CalGreen requirements. However, since the proposed Project cannot demonstrate how it would meet the long-term 2050 reduction goal, GHG impacts would be conservatively considered to have a considerable contribution to a significant cumulative GHG impact.

3.3.2.4 Mitigation Measures
The following mitigation measures are required for the proposed project.

Mitigation Measure GHG-1. The City of Corona shall update the Climate Action Plan (CAP) every five years to ensure the City is monitoring the plan’s progress toward achieving the City’s greenhouse 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

gas (GHG) reduction target and to require amendment if the plan is not achieving specified level. The update shall consider a trajectory consistent with the GHG emissions reduction goal established under Executive Order S-03-05 for year 2050 and the latest applicable statewide legislative GHG emission reduction that may be in effect at the time of the CAP update (e.g., Senate Bill 32 for year 2030). The CAP update shall include the following:
• GHG inventories of existing and forecast year GHG levels. • Tools and strategies for reducing GHG emissions to ensure a trajectory with the long-term GHG reduction goal of Executive Order S-03-05.
• Plan implementation guidance that includes, at minimum, the following components consistent with the proposed CAP:
o Administration and Staffing
o Finance and Budgeting
o Timelines for Measure Implementation
o Community Outreach and Education
o Monitoring, Reporting, and Adaptive Management
o Tracking Tools

3.4 LAND USE AND PLANNING

3.4.1 Environmental Setting
The City is located in the northwestern portion of Riverside County, near the convergence of Los Angeles, Orange, and Riverside Counties and is located 45 miles southeast of the City of Los Angeles (City of Corona 2019). The City is bordered by the City of Norco to the north, City of Riverside to the east, and Riverside County to the west and the south. The City encompasses approximately 25,551 acres with its SOI consisting of an additional 16,515 acres. The City currently has 31 specific plan areas where growth buildout would occur.

The Project site expands across various urban and suburban areas of the City. The City is bounded on the south and west by open space, to the north by the City of Norco, and to the east by the City of El Cerrito.

As discussed above, these areas of the City are comprised of various General Plan land use designations and zoning areas. During evaluation of the site adequacy of potential future housing developments, the 100 candidate sites were selected for rezoning to the AHO zoning. Additionally, there are 57 additional parcels selected as potential sites for rezoning to a high density residential designation.

3.4.1.1 Regulatory Framework
State
General Plans
The land use planning and zoning authority of local jurisdictions in California is set forth in the state’s planning laws. California Government Code (CGC) Section 65300, et seq. obliges cities and counties to adopt and implement general plans. The general plan is a comprehensive, long-term, and general document that describes plans for the physical development of a city or county and of any land outside its boundaries that, in a city’s or county’s judgment, bears relation to its planning. The general plan addresses a broad range of topics including, at a minimum, land use, circulation, housing, conservation, open space, noise, and safety. In addressing these topics, the general plan identifies the goals, objectives, policies, principles, standards, and plan proposals that support the city’s or county’s vision for the area. The general plan is a long-range document that typically addresses the physical character of an area over a 20-year period. Although the general plan serves as a blueprint for future development and identifies the overall vision for the planning area, it remains general enough to allow flexibility in the approach taken to achieve the plan’s goals.

State Zoning Law
The State Zoning Law (CGC Section 65800, et seq.) establishes that zoning ordinances, which are laws that define allowable land uses within a specific district, are required to be consistent with the general plan and any applicable specific plans. When amendments to the general plan are made, corresponding changes in the zoning ordinance may be required within a reasonable time to ensure the land uses designated in the general plan would also be allowable by the zoning ordinance (CGC Section 65860, sub.[c]).

Southern California Association of Governments
SCAG is a council of governments representing Imperial, Los Angeles, Orange, Riverside, San Bernadino, and Ventura counties. SCAG is the federally recognized metropolitan planning organization for this region, which encompasses over 38,000 square miles. SCAG is a regional planning agency and a forum for addressing regional issues concerning transportation, the economy, community development, and the environment. SCAG is also the regional clearinghouse for projects requiring environmental documentation under federal and state law. In this role, SCAG reviews proposed development and infrastructure projects to analyze their impacts on regional planning programs. SCAG has developed regional plans to achieve specific regional objectives including the 2020-2045 RTP/SCS Plan (City of Corona 2019).

Local
City of Corona General Plan
The City’s General Plan was most recently updated and adopted by the City Council on June 3, 2020. The 2020-2040 General Plan Update presents a vision for the City’s future and a strategy to make that vision a reality. The General Plan is a comprehensive long-range plan that provides a framework for the City’s physical, economic, social, and environmental development. The General Plan includes goals and policies identified to describe ideal future conditions for the City and provides guidance to assist the City decisionmakers. Goals and policies identified in the General Plan that are applicable to the Project are described below in Table 3.4-1.

Corona Zoning Code
The Corona Zoning Code consists of a zoning map that delineates the boundaries of zoning designations within the City and regulations that govern the use of land and placement of buildings and improvements within the various class districts. The purpose of the Zoning Code is to implement the City’s General Plan and can be found under Title 17 of the Municipal Code.

3.4.2 Impact Discussion

3.4.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to land use and planning are significant. Would the Project:
• Physically divide and established community?
• Cause a significant environmental impact due to a conflict with any applicable land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-51

3.4.2.2 Project Impacts
Would the Project physically divide an established community? Finding: Same Impact as Approved Project (Less than Significant Impact) The Project sites identified for rezoning and AHO zone overlay for the Project are located primarily within the highly developed central portion of the City where adjacent lands are developed with existing uses.

Development of sites identified for the Project may result in changes to existing land use patterns; however, new developments within the City would be required to comply with and implement applicable General Plan policies that would improve connectivity and compatibility with existing and planned uses. The candidate sites identified for future residential development resulting from Project implementation are unlikely to cause major changes to the circulation system or land use patterns of the area and would be located within already established communities. Furthermore, the candidate sites are primarily situated along an established HQTA. Therefore, future residential development resulting from Project implementation would not physically divide an established community, and impacts would be less than significant.

Would the Project cause a significant environmental impact due to a conflict with any applicable land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Finding: Less Impact than Approved Project (Significant and Unavoidable Impact) General Plan Consistency Analysis
The analysis provided in Table 3.4-1 demonstrates that the Project would not create inconsistencies with the applicable goals and policies of the General Plan.

Table 3.4-1: General Plan Consistency Analysis
Policy Consistency Analysis
Land Use
Goal LU-1: A community that contains a diversity of
land uses that support the needs of and provide a high
quality of life for its residents, sustain and enhance the City’s economic and fiscal balance, are supported by
adequate community infrastructure and services, and
are compatible with the environmental setting and
resources.

Consistent. The conversion of the Project’s identified
parcels to high density residential and AHO zone would
allow for a diversity of residential developments to
occur within the City and would support the needs of
the City for the future development of affordable
housing. The identified parcels are located within
urbanized areas of the City and would be supported by
existing infrastructure and services.

Policy LU-1.1: Accommodate uses that support the
diverse needs of Corona’s residents, including
opportunities for living, commerce, employment,
recreation, education, culture, entertainment, civic
engagement, and social and spiritual activity that are in balance with natural open spaces.

Consistent. Project implementation would allow for
development of affordable housing within the City to
meet the City’s RHNA allocation and the needs of the
City’s residents. Furthermore, future residential
development resulting from Project implementation
would be clustered around an established HQTA,
affording future residents the ability to utilize public transit and alternative modes of transportation to be

more connected to resources throughout the City and
more engaged in civic activities.

Policy LU-1.4: Accommodate the types, densities, and
mix of land uses that can be adequately supported by
transportation and utility infrastructure (water, sewer, etc.) and public services (schools, parks, libraries, etc.) Consistent. Future residential development resulting
from Project implementation is specifically intended to support a mix of uses that can be supported by existing transportation and utility infrastructure, as future uses will be able to conveniently utilize public transit within a HQTA. Existing and future utility infrastructure and
public services would be able to accommodate
increased future residential development projects, and
each future project will be required to undertake its own evaluations to ensure the availability of resources
required.

Goal LU-3: A development pattern that retains and
complements the City’s important residential
neighborhoods, commercial and industrial districts, and open spaces.

Consistent. Project implementation would not change
the character of the City’s important residential
neighborhoods or open spaces; however, future
implementing residential development would be
permitted in current commercial and industrial districts where AHO zoning would be implemented. The overall
integration of future residential development would be
consistent with the overall development pattern of these areas as feasible.

Policy LU-3.1: Permit land uses and developed
consistent with the Corona General Plan Land Use
Designations.

Consistent. With Project approval, including
establishment of the new AHO zone and other
rezoning, future residential development would be
consistent with existing General Plan Land Use
designations.

Policy LU-3.2: Require that development not exceed
the maximum density of land use designations allowed
by the general plan and implemented through zoning
districts.

Consistent. With Project approval, including
establishment of the new AHO zone, future residential
development would be consistent with existing land use
designations allowed by the General Plan.

Policy LU-3.3: Allow flexibility in the defined land use types, densities, and intensities to account for changes in housing needs and characteristics, industrial and
employment markets, and retail commercial enterprises
that will occur during the implementation of this plan.

Such deviations shall be considered only when found to
be consistent with the plan’s vision, goals, and overall policy intentions for community places, character,
economy, environmental sustainability, and public
safety.

Consistent. The establishment of the AHO zone would
allow for more flexibility in the development of sites
designated under the AHO zone. The AHO zone would
cover existing properties that are currently developed
with non-residential land uses. The General Plan
designations and zoning would remain, with overlays
added, which would allow property owners to have the
option to develop the site under either set of standards (the underlying General Plan and zoning or the AHO).

Goal LU-4: Strategic growth that preserves viable
residential neighborhoods and commercial and
industrial districts, targets new development to parcels that are environmentally suitable and can be supported
by infrastructure and services, and re-uses appropriate properties to enhance their economic vitality and
community livability.

Consistent. Future residential development associated
with Project implementation is intended to preserve
existing neighborhoods and districts and retain these
land uses, as the AHO zone would allow for more
development flexibility in these areas. The clustering of future development within an existing HQTA provides
opportunities for increased economic vitality and
livability by allowing future residents the ability to take advantage of alternative modes of transportation to
work, live and play.

Policy LU-4.1: Accommodate future growth and
development in accordance with Figure LU-1, the land
use plan. This depicts lands on the City’s periphery and Consistent. Future residential development resulting
from Project implementation would be consistent with
the future growth and development depicted in General

within the existing urbanized area for which
development may be considered for re-use and
intensified development.

Plan Figure LU-1, as vacant and underutilized sites
located mainly within existing urbanized areas would be the focus of appropriate infill re-use and intensified
residential development.

Policy LU-4.4: Proactively promote the adaptive re-use
and infill of economically underutilized, obsolete, and dilapidated commercial and industrial sites within
existing urbanized areas, in consideration of the uses, scale, and character of adjoining uses.

Consistent. Parcels identified for Project
implementation consist of sites located within urbanized areas identified as vacant or underutilized by the City.

The rezoning and AHO zone would promote the re-use
and infill of these sites within existing urbanized areas.

Goal LU-7: Residential neighborhoods that contain a
diversity of housing and supporting uses to meet the
needs of Corona’s residents and that are designed to
enhance livability and a high quality of life.

Consistent. Project implementation would allow for a
diversity of housing types to be developed within the
City, and all future developments would be required to
be designed and constructed to enhance livability and
quality of life, in accordance with the General Plan and applicable City requirements.

Policy LU-7.1: Accommodate the development of a
diversity of residential housing types that meet the
needs of Corona’s population in accordance with the
Land Use Plan’s designations, applicable density
standards and design and development policies, and
the adopted housing element.

Consistent. The purpose of the Project is to
accommodate the City’s RHNA requirements for
affordable housing and would help the City meet the
housing needs of the City’s growing population.

Goal LU-9: Development of new residential
neighborhoods that complement existing
neighborhoods, contain a mix of neighborhoodsupportive land uses, exhibit high quality architectural design, and ensure a high level of livability for their residents.

Consistent. The sites identified for future residential development resulting from Project implementation are
located throughout the City and would allow for a
diversity of residential developments to occur. All new developments resulting from Project implementation
would be required to be designed and constructed to
complement existing neighborhoods.

Policy LU-9.1: Accommodate the development of new
residential neighborhoods in areas depicted by the land use plan and growth and development policy plan that
contain a diversity of housing and supporting schools,
parks, and other amenities.

Consistent. The sites identified for future residential development resulting from Project implementation are
located throughout the City and would integrate high
density residential and AHO zones into areas to allow
for a diversity of housing developments.

Policy LU-9.4: Design the distribution of residential land uses to avoid the overconcentration of multi-family units by limiting their number in any single location and
providing for their dispersal throughout the
neighborhoods.

Consistent. The Project has identified sites throughout the City for rezoning to high density residential and
AHO zone. The identified parcels are spread out
throughout the City limits and are not concentrated in
any single location in the City. Furthermore, many of
the identified sites are clustered around the established HQTA, thereby allowing the movement of residents
throughout the City.

Housing
Goal H-1: Promote and maintain a balance of housing
types and corresponding affordability levels to provide for the community’s demands for housing within all
economic segments of the City.

Consistent. Project implementation would include
rezoning and establishment of AHO zones to designate
Project sites to accommodate the future planning and
development of low- and moderate-income housing.

Policy H-1.3: Provide sites for residential development so that scarcity of land does not unduly increase the
cost or decrease the availability of housing for all
segments of the community.

Consistent. Project implementation would convert
vacant or underutilized parcels within the City to high density residential or AHO zones to provide more
residential development opportunity sites for all
segments of the community.

Policy H-1.5: Create or expand zoning designations and
commensurate development standards to encourage
flexibility in permitted land use.

Consistent. Implementation of the Project would
include the establishment of an AHO zone which is a
new zone proposed by the City to establish by-right
development standards for affordable housing projects.

The AHO zone would cover existing properties that are
currently developed with non-residential land uses. The property owner would be allowed to have the option to
develop the site with either the underlying General Plan and zoning designation standards or the AHO overlay
standards, thereby creating and expanding more
flexible development standards.

Corona Zoning Code Consistency
The Project is proposing a rezoning program to accommodate the planning of low- and moderate-income households as required by the state’s RHNA allocation for the City. The City’s Housing Element Update includes an inventory of properties that are intended to be rezoned to high density residential or an AHO zone in order to plan for potential sites to accommodate the RHNA allocation of units that would also be suitable for low- and moderate-income units. The AHO zone is a new zone being proposed by the City to establish by-right development standards for affordable housing projects. The City is proposed to create development standards (i.e., criteria for building setbacks, parking, building height, landscaping, open space amenities, lot coverage, etc.) and architectural design guidelines for the AHO zone. While the zoning designations for identified Project parcels would change following the approval of the Project, the change would result in an increase of potential affordable housing sites within the City and would allow for the development of a diversity of developments as planned by the General Plan.

As this SEIR is analyzing proposed modifications to the General Plan through a rezoning program to accommodate the planning of low- and moderate-income households as required by the state’s RHNA allocation for the City, the proposed Project is ultimately implementing the General Plan. All future projects proposing development on identified Project parcels would be required to comply with the City’s General Plan and demonstrate consistency with the General Plan and zoning code through project design or the implementation of mitigation measures. Project implementation would allow for the development of affordable housing within the City and would result in a diversity of residential developments throughout the City. Project implementation would not conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect; therefore, impacts would be less than significant.

3.4.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative land use and planning impact?
Finding: Same Impact as Approved Project (Less than Significant Cumulative Impact) The General Plan Updated EIR considered the extent of cumulative impacts associated with the General Plan area as contiguous with the City and SOI boundary but also considers regional land use planning.

land use analysis provided found that future residential development resulting from Project implementation would be consistent with the City’s General Plan. Other developments in the Project vicinity would be required to demonstrate consistency with the General Plan through project design or the implementation of mitigation measures. Therefore, Project implementation, in conjunction with other planned projects, would not have a cumulatively considerable impact on land use. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3.5 NOISE

3.5.1 Environmental Setting

3.5.1.1 Sensitive Receptors and Ambient Noise Levels
Certain land uses, such as residences, schools, and hospitals are particularly sensitive to noise and vibration. Sensitive receptors within the City include residences, senior housing, schools, places of worship, and recreational areas. These uses are regarded as sensitive because they are where people most frequently engage in activities involving reading, studying, sleeping, resting, or passive recreation, which can be disturbed by noise. Commercial and industrial uses are not particularly sensitive to noise or vibration.

For the preparation of the General Plan Update EIR, noise monitoring was conducted at several locations in the City and measurements were made during weekday periods when it was expected to be most active.

Long-term (24 hour) measurements were taken at four locations within the City and short-term (15 minute) measurements were conducted at twelve locations around the City. According to the General Plan Update EIR, the noise environment within the City and SOI is highly variable, depending on the location. Freeway noise from Interstate 15 and SR 91 tend to control the noise environment at most locations and in general, noise monitoring locations that experience less than 50 dB(A) equivalent continuous noise level (Leq) were located relatively far from these major freeway sources. The time-averaged sound level in the City was in the range of 45 to 65 dB(A) Leq.

3.5.1.2 Regulatory Framework
Federal
The USEPA has identified the relationship between noise levels and human response. The USEPA set a day-night noise level of 55 dB(A) day-night average sound level over a 24-hour period (Ldn) as the basic goal for exterior residential noise intrusion. However, other federal agencies, in consideration of their own program requirements and goals, as well as difficulty of achieving a goal of 55 dB(A) Ldn, have settled on the 65 dB(A) Ldn level as their standard. At 65 dB(A) Ldn, activity interference is kept to a minimum, and annoyance levels are still low. It is also a level that can realistically be achieved in most locations.

State
California Building Code
CCR Part 2, Title 24 are the California Noise Insulation Standards which establish minimum noise insulation standards to protect persons within new hotels, motels, dormitories, long-term care facilities, apartment houses, and dwellings other than single-family residences. Under Section 1207.11 “Exterior Sound Transmission Control”, interior noise levels attributable to exterior noise sources cannot exceed 45 dB(A) Ldn in any habitable room. Where such residences are in an environment where exterior noise is 60 dB(A) Ldn or greater, an acoustical analysis is required to ensure interior levels do not exceed the 45 dB(A) Ldn interior standard. If the interior allowable noise levels are met by requiring that windows be kept closed, the 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

design for the building must also specify a ventilation or air conditioning system to provide a habitable interior environment.

California Green Building Standards Code
CALGreen establishes interior noise insulation standards for non-residential occupied buildings. The CALGreen code also applies to occupied non-residential spaces within a multifamily residential building, such as community rooms, offices, etc. CALGreen Section 5.507 “Environmental Comfort”, states the following:

5.507.4.1 Exterior noise transmission. Wall and roof-ceiling assemblies exposed to the noise source making up the building or addition envelope or altered envelope shall meet a composite Sound Transmission Class (STC) rating of at least 50 or a composite OITC rating of no less than 40, with exterior windows of a minimum STC of 40 or OITC of 30 in the following locations:

1. Within the 65 CNEL noise contour of an airport
Exceptions:

1. Ldn or CNEL for military airports shall be determined by the facility Air Installation Compatible Land Use Zone (AICUZ) plan.

2. Ldn or CNEL for other airports and heliports for which a land use plan that has not been developed shall be determined by the local general plan noise element.

3. Within the 65 CNEL or Ldn noise contour of a freeway or expressway, railroad, industrial source or fixed-guideway notice source as determined by the Noise Element of the General Plan.

5.507.4.1.1 Noise exposure where noise contours are not readily available. Buildings exposed to a noise level of 65 dB Leq-1-hr during any hour of operation shall have building, addition or alteration exterior wall and roof-ceiling assemblies exposed to the noise source meeting a composite STC rating of at least 45 [or Outdoor/Indoor Transmission Class (OITC) 35], with exterior windows of a minimum STC of 40 (or OITC 30).

5.507.4.2 Performance method. For buildings located as defined in Section 5.507.4.1 or

5.507.4.1.1, wall and roof-ceiling assemblies exposed to the noise source making up the building or addition envelope or altered envelope shall be constructed to provide an interior noise environment attributable to exterior sources that does not exceed an hourly equivalent noise level (Leq -1Hr) of 50 dBA in occupied areas during any hours of operations

5.507.4.2.1 Site features. Exterior features such as sound walls or earth berms may be utilized as appropriate to the building, addition, or alteration project to mitigate sound migration to the interior.

5.507.4.2.2 Documentation of compliance. An acoustical analysis documenting complying interior sound levels shall be prepared by personnel approved by the architect or engineer of record. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

5.507.4.3 Interior sound transmission. Wall and floor-ceiling assemblies separating tenant spaces and tenant spaces and public places shall have an STC of at least 40.

Local
The City has set performance standards for noise and vibration sources in the City Municipal Code. Chapter

9.24, Loud and Unnecessary Noise, defines the qualitative standards used in determining a potential violation. Municipal Code Section 17.84.040, “Noise”, provides performance standards for two separate types of noise sources: transportation and stationary (i.e. heating, ventilation and air conditioning (HVAC) sources). Table 3.5-1 below shows the acceptable interior and exterior noise limits for various land uses.

The exterior noise limits in the table are based on the land use compatibility guidelines in General Plan Update EIR Table 5.13-3.

3.5.2 Impact Discussion

3.5.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following questions were analyzed and evaluated to determine whether impacts to noise are significant. Would the Project result in:
• Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
• Generation of excessive groundborne vibration or groundborne noise levels.

The following issue was determined to have no impact or a less than significant impact during the Initial Study and NOP Scoping process. This issue was sufficiently analyzed in the Initial Study and are not discussed further in this section. Would the Project result in:
• For a project located within the vicinity of a private airstrip or an airport land use plan, or where such a plan has not been adopted within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?

3.5.2.2 Project Impacts
Would the Project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Finding: Same Impact as Approved Project (Significant and Unavoidable) Temporary Construction Noise
Under the new Housing Element update, a major source of temporary noise within the City would be from the demolition and/or construction of new buildings and structures. Construction activities within the City -

L J

Environmental Setting, Impacts and Mitigation
3-60
would involve both off-road construction equipment (e.g., excavators, bulldozers, cranes, etc.) and transport of workers and equipment to and from construction sites. Table 5.13-10 in the General Plan Update EIR lists the noise levels for construction equipment that would likely be used during future construction areas within the City based on a distance of 50 feet between the equipment and the noise receptor. Since specific future projects within the City are unknown at this time, it is conservatively assumed that the construction areas associated with these future projects could be located within 50 feet of sensitive land uses.

Construction noise is a major source of temporary noise within the City and would continue to be so regardless of whether or not the proposed Project is implemented. Noise levels near individual future construction sites resulting from Project implementation would not be substantially different from what they would be under the existing planning protocol. All development projects in the City would still be subject to the time restrictions listed in the City of Corona Municipal Code and the requirements contained within General Plan Update EIR Mitigation Measure N-1. Therefore, the impact of future residential development resulting from Project implementation with respect to temporary construction noise would remain significant and unavoidable, as noted in the General Plan Update EIR.

Stationary Noise Sources
Future residential development resulting from Project implementation would cause new noise-producing stationary sources, such as condensing units, fans, and air conditioning units, contained within developed areas of the City. All stationary noise sources would be analyzed on a project-by-project basis and will be subject to the standards and limits listed in Section 17.84.040(c)(2) in the City of Corona Municipal Code.

Therefore, the impact of Project implementation related to stationary source noise is less than significant.

Exterior Traffic Noise
Traffic noise depends primarily on vehicle speed (tire noise increases with speed), proportion of medium and large truck traffic (trucks generate engine, exhaust, and wind noise in addition to tire noise), and number of speed control devices, such as traffic lights and stop signs (accelerating and decelerating vehicles and trucks can generate more noise).

Changes in traffic volumes can also have an impact on overall traffic noise levels. For example, it takes 25 percent more traffic volume to produce an increase of only 1 dB(A) in the ambient noise level. For roads already heavy with traffic volume, an increase in traffic numbers could even reduce noise because the heavier volumes could slow down the average speed of the vehicles. A doubling of traffic volume results in a 3 dB(A) increase in noise levels.

Table 5.13-11 “Traffic Noise Increases Along Study Roadway Segments” in the General Plan Update EIR shows the buildout of the General Plan would result in no significant traffic noise increases along the study roadway segments from implementation of the General Plan Update. The noise increases due to traffic listed in Table 5.13-11 range between 0.0 and 2.1 dB(A) CNEL, which is below the industry-standard 3 dB(A) CNEL impact determination threshold.

Future residential development resulting from Project implementation may result in very slight increases of traffic volumes over what was analyzed in the General Plan Update EIR, due to the increased density of 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-61
housing. These projects, however, would need to increase total traffic volumes by 25 to 50 percent to reach the 3 dB(A) CNEL threshold, depending on roadway. The exact impact of potential increased traffic from future implementing residential projects will be analyzed on a project-by-project basis, and any mitigation would be developed based on the General Plan Policies. Therefore, the impact related to exterior traffic noise is less than significant.

Interior Traffic Noise
As a result of Project implementation, new residential development would be subject ambient noise levels generated from exterior sources at each project site, such as traffic, existing mechanical equipment, and nature-based noises. The interior noise levels received by future residential development resulting from Project implementation will analyzed on a project-by-project basis and would be subject to the requirements listed in the California Building Code, CALGreen, and the City of Corona General Plan Policies. This would not be substantially different from current requirements, and therefore, the impact on interior traffic noise would be less than significant.

Operational Noise
As a result of Project implementation, new residential projects may contain exterior amenity spaces, such as playgrounds or sport courts. Noise would also be generated from the future operation of residential projects, such as trash pickup. The noise generated from operation of these facilities will also be analyzed on a project-by-project basis and would be subject to the requirements in the City of Corona General Plan Policies. This again would not be substantially different from existing requirements, and therefore, the impact on operational noise would be less than significant.

Would the Project result in generation of excessive groundborne vibration or groundborne noise levels?
Finding: Same Impact as Approved Project (Less than Significant Impact with Mitigation) Construction activities would occur in a variety of locations throughout the City as a result of Project implementation, which may require activities or use of off-road equipment known to generate some degree of vibration. Activities that would potentially generate excessive vibration, such as blasting or impact pile driving, would not be expected to occur from residential housing development. Receptors sensitive to vibration include structures (especially older masonry and historic structures), people (especially residents, the elderly, and the sick), and equipment (e.g., magnetic resonance imaging equipment, optical and electron microscopes).

Since specific future projects within the City are unknown at this time, it is conservatively assumed that the construction areas associated with these future residential projects could be located within 50 feet of sensitive land uses. The primary vibration-generating activities associated with Project implementation would occur during grading, placement of underground utilities, and construction of foundations. Vibration levels near individual construction sites related to future residential development resulting from Project implementation would not be substantially different from what they would be under the existing regulatory requirements. All projects constructed will still be subject to the time restrictions listed in the City of Corona 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-62
Municipal Code and requirements contained within General Plan Update EIR Mitigation Measure N-2.

Therefore, the impact of Project implementation on temporary construction vibration would be less than significant.

3.5.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative noise impact?
Finding: Same Impact as Approved Project (Less than Significant Cumulative Impact) Temporary Construction Noise
If future residential development resulting from Project implementation are constructed simultaneously with other nearby projects, cumulative construction noise levels should be higher than those experienced if implementing projects were developed alone. While the potential exists for implementing construction projects and other foreseeable development to occur simultaneously and in close proximity to one another, construction equipment operations would still be bound by the constraints of the City of Corona Municipal Code and requirements contained within General Plan Update EIR Mitigation Measure N-1. Therefore, impacts associated with future construction activities conflicting with local noise standards would be less than significant.

Stationary Noise Sources
Development that is associated with the implementation of the proposed Project combined with cumulative projects could result in stationary source noise levels higher than those experienced if implementing projects were developed alone. At the present time, the type, size, and the location of any exterior noiseproducing equipment that may be associated with housing developed associated with Project implementation is unknown. As discussed in Section 3.5.2, stationary noise sources on all past, present, and reasonably foreseeable projects would be subject to the standards and limits listed in Section

17.84.040(C)(2) in the City of Corona Municipal Code. Therefore, the cumulative impact with respect to stationary noise sources potentially resulting in a substantial permanent increase in ambient noise levels in the vicinity of the implementing project in excess of standards established in the local general plan or noise ordinance would be less than significant.

Construction Vibration
Development that could occur with the implementation of the proposed Project could again be constructed simultaneously with other nearby projects. Because vibration impacts are based on instantaneous peak particle velocity (PPV) levels, worst-case groundborne vibration levels from construction are generally determined by whichever individual piece of equipment generates the highest vibration levels. Unlike the analysis for average noise levels, in which noise levels of multiple pieces of equipment can be combined to generate a maximum combined noise level, instantaneous peak vibration levels do not combine in this way. Vibration from multiple construction sites, even if they are located close to one another, would not combine to raise the maximum PPV. For this reason, the cumulative impact of construction vibration from 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-63
multiple construction projects located near one another would generally not combine to further increase vibration levels. In essence, vibration effects are highly localized.

Vibration impacts resulting from construction of subsequent future residential development resulting from Project implementation would not combine with vibration effects from cumulative projects in the vicinity.

Therefore, cumulative groundborne vibration impacts related to potential damage effects would be less than significant.

Exterior Traffic Noise
Development that could occur with future Project implementation and simultaneous development of other nearby projects could result in greater roadside noise levels generated by an increase in roadway traffic.

As discussed in the General Plan Update EIR, none of the sensitive land uses along roadway segments would be exposed to an increase in traffic noise that would be considered substantial based on industrystandard thresholds. The roadway volumes, and associated noise levels, assumed in the analysis in Table

5.13-11 in the General Plan Update EIR include traffic generated by the past, present, or reasonably foreseeable future projects. Therefore, the analysis presented in Impact 5.13-2 in the General Plan Update EIR represents a cumulative traffic noise analysis and the cumulative increase in roadside noise levels would be less than significant.

3.5.2.4 Mitigation Measures
The following mitigation measures are required for the proposed project.

Mitigation Measure N-1. Construction contractors shall implement the following measures for construction activities conducted in the City. Construction plans submitted to the City shall identify these measures on demolition, grading, and construction plans submitted to the City. The City Corona Public Works Department shall verify that grading, demolition, and/or construction plans submitted to the City include these notations prior to issuance of demolition, grading and/or building permits. • During the active construction period, equipment and trucks used for project construction shall utilize the best available noise control techniques (e.g., improved mufflers, intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds), wherever feasible. • Impact tools (e.g., jack hammers and hoe rams) shall be hydraulic- or electric-powered wherever feasible. Where the use of pneumatic tools is unavoidable, an exhaust muffler on the compressed air exhaust shall be used along with external noise jackets on the tools. • Stationary equipment such as generators and air compressors shall be located as far as feasible from noise-sensitive uses.
• Stockpiling shall be located as far as feasible from noise-sensitive receptors. • Construction traffic shall be limited—to the extent feasible—to approved haul routes established by the City.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-64
• Prior to the start of construction activities, a sign shall be posted at the entrance(s) to the job site, clearly visible to the public, that includes permitted construction days and hours, as well as the contact information of the City’s and contractor’s authorized representatives that are assigned to respond in the event of a noise or vibration complaint. If the authorized contractor’s representative receives a complaint, they shall investigate, take appropriate corrective action, and report the action to the City.
• Signs shall be posted at the job site entrance(s), within the on-site construction zones, and along queueing lanes (if any) to reinforce the prohibition of unnecessary engine idling. All other equipment shall be turned off if not in use for more than 5 minutes. • During the entire active construction period and to the extent feasible, the use of noiseproducing signals, including horns, whistles, alarms, and bells, shall be for safety warning purposes only. The construction manager shall be responsible for adjusting alarms based on the background noise level, or to utilize human spotters when feasible and in compliance with all safety requirements and laws.
• When construction noise is predicted to exceed established noise standards and when the anticipated construction duration is two years or more, contractors shall erect temporary noise barriers, where feasible.

Mitigation Measure N-2. Prior to issuance of a building permit for a project requiring pile driving during construction within 135 feet of fragile structures such as historical resources, 100 feet of nonengineered timber and masonry buildings (e.g., most residential buildings), or within 75 feet of engineered concrete and masonry (no plaster), or a vibratory roller within 25 feet of any structure, the project applicant shall prepare a noise and vibration analysis to assess and mitigate potential noise and vibration impacts related to these activities. This noise and vibration analysis shall be conducted by a qualified and experienced acoustical consultant or engineer. The vibration levels shall not exceed Federal Transit Administration (FTA) architectural damage thresholds (e.g., 0.12 in/sec PPV for fragile or historical resources, 0.2 in/sec PPV for non-engineered timber and masonry buildings, and 0.3 in/sec PPV for engineered concrete and masonry), or the City threshold of 0.05 in/sec RMS (94 VdB). If vibration levels would exceed this threshold, alternative uses such static rollers and drilling piles as opposed to pile driving shall be used.

3.6 PUBLIC SERVICES

3.6.1 Environmental Setting
The City offers built and natural trails, developed parks, and golf courses as some of the recreational opportunities in the City. Corona has 35 public parks covering approximately 352 acres, which does not include natural open space areas such as Fresno Canyon and Sage Open Space. The public park system in the City includes mini, neighborhood, community, and major/regional arks that are differentiated by scale, population served, and amenities. The City’s Park standard is based on guidance provided by California Government Code Section 666477, referred to as the Quimby Act, and the City has a park standard of 3 acres per 1,000 residents.

3.6.1.1 Regulatory Framework
State
Quimby Act
Section 66477 of the California Government Code, also known as the Quimby Act, was enacted in 1965 in an effort to promote the availability of park and open space areas in California. The Quimby Act authorizes cities and counties to enact ordinances requiring the dedication of land, or the payment of fees for park and/or recreational facilities in lieu thereof, or both, by developers of residential subdivisions as conditions to the approval of a tentative map or parcel map. The Quimby Act requires the provision of three acres of park area per 1,000 persons residing within a subdivision, unless the amount of existing neighborhood and community park exceeds that limit, in which case the city or county may adopt a higher standard not to exceed five acres per 1,000 residents. The Quimby Act also specific acceptable uses and expenditures of funds from fees.

Mitigation Fee Act
The California Mitigation Fee Act allows cities to establish fees that will be imposed upon development projects for the purposes of mitigating the impact that the development projects have upon the city’s ability to provide specific public facilities.

Local
City of Corona Municipal Code
Quimby Act Fees
The City’s Quimby Act is codified in Chapter 16.35, Park Dedication and In-Lieu Fees, in the City’s Municipal Code. As a condition of approval of a tentative or final tract map or parcel map for a residential subdivision, or for a building permit within a subdivision, the subdivider is required to dedicate park land and/or pay an in lieu fee. Recreational facilities provided by a project must be provided in accordance with the standards, specifications and requirements of the City’s General plan, the City’s Park Master Plan, and any other adopted resolution, policy, or standard of the City. The City’s park standard is based on a ratio of 3.0 acres of park area per 1,000 persons. At the time of filing a tentative map application for all subdivisions with 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-66
residential land uses, project applicants may indicate whether they desire to dedicate property for park and recreational purposes onsite or whether they desire to pay a fee in lieu thereof. If they desire to dedicate land, they must designate the area on a tentative map.

Development Impact Fees
City of Corona Municipal Code Chapter 16.23, Development Impact Fees, provides for the means to finance adequate infrastructure and other public improvements and facilities made necessary by the impacts created by new residential and non-residential development in the City. To maintain the current level of service for parks in the City, Chapter 16.24, Improvement Requirements, require payment of development impact fees for recreational facilities to assure the acquisition and improvement of adequate recreational facilities to serve the subsequently annexed areas.

City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and park resources discussed in this section:

Policy LU-1.1: Accommodate uses that support the diverse needs of Corona’s residents, including opportunities for living, commerce, employment, recreation, education, culture, entertainment, civic engagement, and social and spiritual activity that are in balance with natural open spaces.

Policy LU-1.5: Accommodate land use development in balance with the preservation and conservation of open spaces for recreation, aesthetic relief, natural resource value, and public safety (such as floodways, seismic fault zones, and other).

Policy LU-1.8: Integrate a complementary mix of open spaces (including parks, trails, and landscaping) within the City’s existing urban fabric to enhance character, soften hardscapes, beautify the community, and create a high quality of life.

Policy LU-5.13: Require that new master-planned residential subdivisions incorporate parks, greenways, and open spaces as character-defining amenities for their residents, emphasizing the retention of natural landforms and important plant communities.

• Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:
o Parks?
The following issues were determined to have no impact or a less than significant impact during the Initial Study and NOP Scoping process. These issues were sufficiently analyzed in the Initial Study and are not discussed further in this section. Would the Project:
• Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:
o Fire protection?
o Police protection?
o Schools?
o Other Public Facilities?

3.6.2.2 Project Impacts
Would the Project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:

Parks?
Finding: Same Impact as Approved Project (Less than Significant Impact) The City’s park standard is based on the guidance provided by the Quimby Act, and the City has a park standard of 3 acres per 1,000 residents. As impacts on parks are population-driven and the Project proposes rezoning and establishment of AHO zones to accommodate more residential developments, Project implementation could result in substantial adverse physical impacts associated with the need for new or physically altered park facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios.

The General Plan Update EIR anticipated and analyzed an additional 5,494 residential units, which is 594 units less than the City’s RHNA allocation. The 594 additional housing units required to meet RHNA allocation would result in a population growth of approximately 1,972 residents which equals a 1.07 percent increase in population from what was estimated at buildout of the General Plan. The 594 additional housing units required to meet RHNA and the surplus provided by the buffer would represent in total, an increase population growth of approximately 9,900 residents or 5.4 percent increase in population estimated at General Plan buildout. This would result in an increase in parkland demand of approximately 30 acres.

The City’s General Plan Update EIR identified that with the inclusion of golf courses available for public use and natural open space in or adjacent to the City, the City had more than adequate publicly available recreational land in the City and SOI. Additionally, as described above under the Regulatory Framework, Chapter 16.35, Park Dedication and In-Lieu Fees, of the City’s Municipal Code requires the dedication of park land and/or payment of an in-lieu fee for new developments within the City. Additionally, City Municipal Code Chapter 16.23, Development Impact Fees, provides for the means to finance adequate infrastructure and other public improvements and facilities made necessary by the impacts created by new residential and non-residential development in the City. To maintain the current level of service for parks in the City, Chapter 16.24, Improvement Requirements, require payment of development impact fees for recreational facilities to assure the acquisition and improvement of adequate recreational facilities to serve the subsequently annexed areas.

In addition to the dedication of land and/or payment of in-lieu fees, park facilities provided by future implementing development projects would be provided in accordance with the standards, specifications and requirements of the City’s General plan, the City’s Park Master Plan, and any other adopted resolution, policy, or standard of the City. Future residential development resulting from Project implementation would be required to implement and comply with General Plan policies related to the provision of parks. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-70
Therefore, with the implementation of required fees and compliance with General Plan policies related to provision of parks, Project implementation would not result in substantial adverse physical impacts associated with the need for new or physically altered park facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios. Impacts would be less than significant.

3.6.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative public services impact?
Finding: Same Impact as Approved Project (Less than Significant Cumulative Impact) Project implementation would result in a less than significant impact related to parks, as described above.

Future residential development resulting from Project implementation is not anticipated to have a cumulative impact on parks such that it would necessitate the construction of new or expanded park facilities that would have adverse physical impacts. Other related projects would be reviewed for impacts on parks on a project-by-project basis and would be required to address any potential impacts with mitigation. Related projects would be required to either dedicate land, or pay a fee in-lieu thereof, or both, as required by the City’s Municipal Code. The dedication of land and payment of fees would offset potential impacts from increased demand for park facilities. Therefore, Project implementation, in conjunction with related projects, would not have a cumulatively considerable impact on parks. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3.7 RECREATION

3.7.1 Environmental Setting
The location of the City near the convergence of three counties allows for residents to access natural open space areas including mountains, hillsides, canyons, and preserves (City of Corona 2019). The Prado Dam Basin, Chino Hills State Park, and Cleveland National Forest are recreational areas located within or near the City and provide recreational opportunities such as hiking, biking, equestrian uses, and camping. Sage Open Space and Fresno Canyon are local natural areas in the community that offer 67 acres of open space for walking, hiking, and bicycling. In addition to established open space areas, the City is part of the Riverside County MSHCP.

The City also offers built and natural trails, developed parks, and golf courses as additional recreational opportunities in the City. Corona has 35 public parks covering approximately 352 acres, not including natural open space areas such as Fresno Canyon and Sage Open Space. The public park system in the City includes mini, neighborhood, community, and major/regional parks that are differentiated by scale, population served, and amenities. The City’s park standard is based on the guidance provided by the Quimby Act, and the City has a park standard of 3 acres per 1,000 residents.

3.7.1.1 Regulatory Framework
State
Quimby Act
Section 66477 of the California Government Code, also known as the Quimby Act, was enacted in 1965 in an effort to promote the availability of park and open space areas in California. The Quimby Act authorizes cities and counties to enact ordinances requiring the dedication of land, or the payment of fees for park and/or recreational facilities in lieu thereof, or both, by developers of residential subdivisions as conditions to the approval of a tentative map or parcel map. The Quimby Act requires the provision of three acres of park area per 1,000 persons residing within a subdivision, unless the amount of existing neighborhood and community park exceeds that limit, in which case the city or county may adopt a higher standard not to exceed five acres per 1,000 residents. The Quimby Act also specific acceptable uses and expenditures of funds from fees.

3-72
The City’s Quimby Act is codified in Chapter 16.35, Park Dedication and In-Lieu Fees, in the City’s Municipal Code. As a condition of approval of a tentative or final tract map or parcel map for a residential subdivision, or for a building permit within a subdivision, the subdivider is required to dedicate park land and/or pay an in lieu fee. Recreational facilities provided by a project must be provided in accordance with eh standards, specifications and requirements of the City’s General plan, the City’s Park Master Plan, and any other adopted resolution, policy, or standard of the City. The City’s park standard is based on a ratio of 3.0 acres of park area per 1,000 persons. At the time of filing a tentative map application for all subdivisions with residential land uses, project applicants may indicate whether they desire to dedicate property for park and recreational purposes onsite or whether they desire to pay a fee in lieu thereof. If they desire to dedicate land, they must designate the area on a tentative map.

City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and recreation resources discussed in this section:

Policy LU-1.1: Accommodate uses that support the diverse needs of Corona’s residents, including opportunities for living, commerce, employment, recreation, education, culture, entertainment, civic engagement, and social and spiritual activity that are in balance with natural open spaces.

Policy LU-5.5: Enhance Corona’s system of parks, greenways, and open spaces by linking these and surrounding natural areas, including along the Temescal Creek, with pedestrian trails and greenways where feasible.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3-73
Policy LU-5.13: Require that new master-planned residential subdivisions incorporate parks, greenways, and open spaces as character-defining amenities for their residents, emphasizing the retention of natural landforms and important plant communities.

Policy LU-9.10: Require that new residential development pay its fair share of the cost of capital improvements, public facilities, and services needed to serve that development. Ensure that funding mechanisms for landscape maintenance and improvements are required for each.

Policy PR-1.1: Seek all creative means to facilitate the provision of at least three acres for every 1,000 residents of useable, attractive, well-maintained, and amenity-appropriate parkland. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3-74
Policy PR-1.2: Provide a variety of park types (e.g., neighborhood, community, major, and special user) with an appropriate mix of amenities that are designed for accessibility and use to meet the diverse needs of residents.

Policy PR-1.3: Encourage distribution of parks, open space, and recreational amenities throughout the City, to the extent feasible, to maximize convenient access for residents, primarily, and secondarily to the business community.

Policy PR-6.2: Require new developments to provide access opportunities to trails that exist in their area or to proposed trails linking parks, recreational areas, neighborhoods, and other areas of high public concentration with a trail designed suitable to the area or contribute improvements, dedications, or fees to extend trails.

3.7.2 Impact Discussion

3.7.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to recreation are significant. Would the Project:
• Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? • Include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?

3.7.2.2 Project Impacts
Would the Project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?
Finding: Same Impact as Approved Project (Less than Significant Impact) As described above under Section 3.6.2, Public Services’ Impact Discission, development of the Project would result in an increase in recreational demand of approximately 30 acres if the identified Project sites are developed with residential developments. Though this Project does not analyze specific developments within the City and only analyzes the rezoning and establishment of AHO zones to provide more residential 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-75
development opportunity sites, some of the identified sites may be developed with residential uses that would include amenities that would provide parks onsite.

The City’s General Plan Update EIR identified that with the inclusion of golf courses available for public use and natural open space in or adjacent to the City, the City had more than adequate publicly available recreational land in the City and SOI. Additionally, since the adoption of the General Plan Update, the City acquired a total of 354 acres of open space in the area of the Skyline Trail near the Cleveland National Forest. The area will be preserved as passive recreation space that supports access to hiking trails located on Skyline, Skinsuit, Tin Mine and Hagador Canyon. As described previously, Chapter 16.35, Park Dedication and In-Lieu Fees, of the City’s Municipal Code requires the dedication of park land and/or payment of an in-lieu fee for new developments within the City and Chapter 16.23, Development Impact Fees, provides for the means to finance adequate infrastructure and other public improvements and facilities made necessary by the impacts created by new residential and non-residential development in the City. To maintain the current level of service for parks in the City, Chapter 16.24, Improvement Requirements, require payment of development impact fees for recreational facilities to assure the acquisition and improvement of adequate recreational facilities to serve the subsequently annexed areas.

The availability of new facilities would prevent the accelerated physical deterioration of existing facilities.

In addition to the dedication of land and/or payment of in-lieu fees, recreational facilities provided by a future implementing residential development project would be developed in accordance with the standards, specifications and requirements of the City’s General Plan, the City’s Park Master Plan, and any other adopted resolution, policy, or standard of the City. Future residential development resulting from Project implementation would be required to implement and comply with General Plan policies related to the provision of recreational facilities.

Therefore, with the implementation of required fees and compliance with General Plan policies related to provision of recreational facilities, Project implementation would not increase the use of existing parks or other recreational facilities such that substantial physical deterioration of the facilities would occur or be accelerated, and impacts would be less than significant.

Would the Project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Finding: Same Impact as Approved Project (Less than Significant Impact) Project implementation does not propose the development of new or expanded recreational facilities.

However, parks are permitted uses under other land use designations such as residential land uses and therefore, Project implementation could result in the development of additional parkland opportunities outside of park-designated parcels. Development and operation of new or expanded parks and recreational facilities may have an adverse physical effect on the environment. However, addressing site specific impacts of these potential parks would be beyond the scope of this SEIR. If a park development is proposed on one of the Project’s candidate sites, subsequent environmental review for individual park developments would be required. Additionally, the General Plan Update EIR identified that potentially adverse impacts to the environment that may result from future expansion or construction of parks and recreational facilities 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-76
pursuant to buildout would be less than significant with the implementation of General Plan policies and state and local regulations related to parks and recreational facilities. Project implementation would not include recreational facilities or require the construction or expansion of recreational facilities which could have an adverse physical effect on the environment, and impacts would be less than significant.

3.7.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative recreation impact?
Finding: Same Impact as Approved Project (Less than Significant Cumulative Impact) As described above, Project implementation would result in an increase in demand for parks and recreational facilities but would have a less than significant impact as identified candidate sites for future development resulting from Project implementation would be required to dedicate land and/or pay fees to offset the potential impacts. Related projects in the area would have the potential to result in a cumulative impact associated increased demand for parks resulting in deterioration of existing parks or requiring construction or expansion of recreational facilities. Related projects would be required to either dedicate land, or pay a fee in-lieu thereof, or both, as required by the City’s Municipal Code. Related projects would be reviewed for impacts on parks on a project-by-project basis and would be required to address any potential impacts with mitigation. As such, Project implementation, in conjunction with related projects, would not have a cumulatively considerable impact on recreation. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3.8 TRANSPORTATION

3.8.1 Environmental Setting
SB 743 caused revisions to the CEQA Guidelines which established new criteria for determining the significance of transportation impacts, so that level of service or other similar measures of vehicular capacity or traffic congestion would not be the sole basis for determining significant impacts under CEQA. The revised CEQA Guidelines utilize the vehicle miles traveled (VMT) metric to evaluate the significance of transportation related impacts for development projects, land use plans, and transportation infrastructure projects. In accordance with SB 743, the City adopted its own thresholds for VMT in May 2019, which accounts for the complete length of the trip from the origin to the destination and assigns 100 percent of that trip distance to the City. The General Plan Update EIR modeled VMT per service population estimates for the City and SOI for home-based trips and employment trips for existing conditions (City of Corona 2019).

Regional and local access roads in Corona include Interstate 15, SR 91, SR 71, 6th Street, Main Street Magnolia Avenue, Ontario Avenue, Cajalco Road, River Road, McKinley Street, Grand Boulevard, Green River Road, Foothill Parkway, El Cerrito Road, Lincoln Avenue, and Hidden Valley Parkway. Riverside Transit Agency provides most of the available bus public transportation on the City and to its surrounding cities. MetroLink Provides commuter rail services via the 91 Line and the Inland Empire/Orange County Line, served by stations in West Corona and North Main Corona. Corona is also closely tied to the Orange County Transportation Authority for bus transit services, and paratransit services also provide alternative modes of flexible passenger transportation on undefined routes for those who need it. The City also adopted a Bicycle Master Plan which calls for bicycle lanes on various streets in order to increase the emphasis on active transportation, which classified bicycle facilities identified throughout the City. Pedestrian facilities exist throughout the City as well (City of Corona 2019).

3.8.1.1 Regulatory Framework
State
SB 743
On September 27, 2013, SB 743 was signed into law, starting a process that fundamentally changed transportation impact analysis as part of CEQA compliance. The legislature found that with the adoption of the SB 375, the state had signaled its commitment to encourage land use and transportation planning decisions and investments that reduce VMT and thereby contribute to the reduction of GHG emissions, as required by the California Global Warming Solutions Act of 2006 (AB 32).

SB 743 eliminates auto delay, level of service (LOS), and other similar measures of vehicular capacity or traffic congestion as the sole basis for determining significant impacts under CEQA. As part of the new CEQA Guidelines, the new criteria “shall promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses” (Public Resources Code Section 21099(b)(1)).
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-78
Pursuant to SB 743, the Natural Resources Agency adopted revisions to the CEQA Guidelines to implement SB 743 on December 28, 2018. The revised CEQA Guidelines establish new criteria for determining the significance of transportation impacts. Under the new Guidelines, VMT-related metric(s) that evaluate the significance of transportation-related impacts under CEQA for development projects, land use plans, and transportation infrastructure projects are required beginning on July 1, 2020. The legislation does not preclude the application of local general plan policies, zoning codes, conditions of approval, or any other planning requirements that require evaluation of LOS, but these metrics may no longer constitute the sole basis for determining transportation impacts under CEQA.

California Department of Transportation
Intersections within incorporated cities associated with freeway on- and off-ramps fall under California Department of Transportation (Caltrans) jurisdiction. Caltrans approves the planning, design, and construction of improvements for all state-controlled facilities. Caltrans utilizes the Highway Capacity Manual 6 (HCM 6) methodology to evaluate intersections within its jurisdiction. LOS criteria for unsignalized intersections differ from LOS criteria for signalized intersections as signalized intersections are designed for heavier traffic and therefore a greater delay. Unsignalized intersections are also associated with more uncertainty for users, as delays are less predictable, which can reduce users’ delay tolerance. For statecontrolled intersections, LOS standards and impact criteria specified by Caltrans will apply.

As stated in the “Guide for the Preparation of Traffic Impact Studies” (2002), “Caltrans endeavors to maintain a target LOS at the transition between LOS ‘C’ and LOS ‘D’ on State highway facilities.” Consistent with the City and County requirements, this analysis defines LOS E or F as deficient for state highway facilities.

Regional
Southern California Association of Governments
SCAG is a council of governments representing Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties. SCAG is the federally recognized metropolitan planning organization for this region, which encompasses over 38,000 square miles. SCAG is a regional planning agency and a forum for addressing regional issues concerning transportation, the economy, community development, and the environment. SCAG is also the regional clearinghouse for projects requiring environmental documentation under federal and state law. In this role, SCAG reviews proposed development and infrastructure projects to analyze their impacts on regional planning programs.

Every four years SCAG updates the RTP for the six-county region that includes Los Angeles, San Bernardino, Riverside, Orange, Ventura, and Imperial counties. On June 5, 2020, the SCAG’s Regional Council adopted the 2020-2045 RTP/SCS. The SCS outlines a development pattern for the region, which, when integrated with the transportation network and other transportation measures and policies, would reduce greenhouse gas emissions from transportation (excluding goods movement). 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

City of Corona Development Impact Fees
The City’s capital improvement plans specify the types of improvements required to achieve circulation and their related goals, and the capital improvement plan provides a schedule of activities needed to fund, construct, and rehabilitate such improvements. The City of Corona has adopted LOS “D” as the minimum acceptable standard for roadway facilities (intersections and roadway segments). At some key locations, such as at heavily traveled freeway interchanges, LOS E may be adopted as the acceptable standard, on a case-bycase basis. Locations that may warrant the LOS E standard include Lincoln Avenue at SR-91, Green River Road at SR-91, Main Street at SR-91, McKinley Avenue at SR-91, Hidden Valley Parkway at I-15, Cajalco Road at I-15, and Weirick Road at I-15. The City requires payment of Development Impact Fees (DIF) per residential unit or non-residential square footage for street and signal improvements in the City to fund transportation improvements to achieve the City’s circulation goals.

City of Corona General Plan
The City of Corona General Plan includes the following policy items relevant to the Project and transportation resources discussed in this section:

Policy CE-1.10: Require a traffic analysis to be prepared in accordance with the City’s adopted Traffic Impact Study Guidelines and require projects to mitigate impacts on the City’s circulation system that exceed the City’s adopted service thresholds for near term and future conditions.

3.8.2 Impact Discussion

3.8.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to transportation are significant. Would the Project:
• Conflict with a program plan, ordinance, or policy addressing the circulation systems, including transit, roadway, bicycle and pedestrian facilities?
• Conflict with or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)? The following issues were determined to have no impact or a less than significant impact during the Initial Study and NOP Scoping process. These issues were sufficiently analyzed in the Initial Study and are not discussed further in this section. Would the Project:
• Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersection(s) or incompatible uses (e.g., farm equipment))? • Result in inadequate emergency access?

Environmental Setting, Impacts and Mitigation
3-80

3.8.2.2 Project Impacts
Would the Project conflict with a program, plan, ordinance, or policy addressing the circulation systems, including transit, roadway, bicycle and pedestrian facilities? Finding: Same Impact as Approved Project (Less than Significant Impact) The Project consists of an update to the City’s Housing Element to rezone parcels or add overlay zones to accommodate the planning of lower- to moderate-income housing. Most of the additional housing is anticipated to be located along major transit corridors, also known as a HQTA. All but three of the AHO and rezone parcels are located within the HQTA and can be presumed to have a less than significant transportation impact. The City’s General Plan EIR identified that buildout would not conflict with a program, plan, ordinance or policy addressing the circulation system and would comply with the City’s General Plan policies and SCAG’s RTP/SCS. Future residential development resulting from Project implementation would result in an increase in demand for public transit, bicycle, and pedestrian facilities which could require the improvement and expansion of the existing circulation system. However, future residential development associated with Project implementation would be required to comply with all applicable programs, plans, ordinances, and policies addressing the circulation system, such as the City’s General Plan and SCAG’s RTP/SCS. The VMT Evaluation (Appendix B) completed for the Project identified that Project implementation would be consistent with the goals of the SCAG’s RTP/SCS. Furthermore, the VMT Evaluation identified that Project implementation within the proposed AHO and rezone parcels would be consistent with the goals and policies of the General Plan by providing job-housing balance. Therefore, impacts would be less than significant as noted in the General Plan EIR.

Would the Project conflict with or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)?
Finding: Less Impact than Approved Project (Significant and Unavoidable Impact) California Governor’s Office of Planning and Research (OPR) and City guidelines state that projects located along a HQTA may be assumed to cause a less than significant transportation impact on VMT because they may improve job-housing balance and/or otherwise generate less VMT. OPR guidelines also recognize that projects with a high percentage of affordable housing may be a basis to find a less than significant impact on VMT than developments located outside of a HQTA; however, the City does not currently include affordable housing as a screening criterion. Since research indicates that low-income earners generate less household VMT overall, affordable housing is more likely to be found to have a less than significant transportation impact.

The VMT Evaluation prepared for the Project found that the majority of Project parcels are located within a HQTA and, therefore, are exempt from VMT analysis due to an assumption of a less than significant transportation impact. Additionally, the remaining AHO and rezone parcels not located within a TPA are recognized by the OPR and SCAG as screened out of VMT analysis, are presumed to generate less household VMT that the uses being replaced or are located within low VMT generating traffic analysis zones. Therefore, they are likely to have a less than significant transportation impact. However, the General 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-81
Plan EIR identified that buildout would result in an increase in VMT from existing conditions and would have a potentially significant impact.

The General Plan EIR identified that future development projects consistent with the General Plan would need to consider transportation demand management (TDM) consistent with those identified in the City’s Circulation Element such as TDM techniques which include incentives to use transit, incentives to form carpools, and making home, work, and shopping closer together to shorten travel distances. The General Plan EIR identified Mitigation Measure T-1 to lessen impacts which would require the City to consider a VMT offset program to offset any increase project-level VMT generated by Project implementation.

However, because the effectiveness of TDM measures included in the General Plan and the feasibility of a VMT offset program has not been determined, the General Plan EIR determined that impacts would be significant and unavoidable. Therefore, though Project implementation would have a less than significant impact on VMT without the incorporation of mitigation, impacts would remain significant and unavoidable as noted in the General Plan EIR.

3.8.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative transportation impact?
Finding: Less Impact than Approved Project (Significant and Unavoidable Impact) The geographic setting for cumulative impacts related to transportation is the City and the regional roadway network surrounding it. Development associated with the implementation of the proposed Project, when combined with cumulative projects, could result in cumulatively considerable transportation impact. Future residential development associated with Project implementation would be required to comply with all applicable programs, plans, ordinances, and policies addressing the circulation system, such as the City’s General Plan and SCAG’s RTP/SCS, and, as such, this impact would be less than significant. Future residential development associated with Project implementation, in conjunction with cumulative projects, would also require transportation evaluations and compliance with all applicable regulations, on a projectby-project basis. Therefore, there would be no cumulatively considerable impact with respect conflicting with a program, plan, ordinance, or policy addressing the circulation systems, including transit, roadway, bicycle and pedestrian facilities.

The VMT Evaluation completed for the Project identified that Project implementation would be consistent with the goals of the SCAG’s RTP/SCS. Furthermore, the VMT Evaluation identified that Project implementation within the proposed AHO and rezone areas would be consistent with the goals and policies of the General Plan. Since the Project would have a less than significant impact related to VMT at the Project level, the Project would have a less than significant impact at the cumulative level per OPR’s Technical Advisory (OPR 2018). However, since the General Plan EIR determined that the effectiveness of TDM measures included in the General Plan and the feasibility of a VMT offset has not yet been determined, this impact would conservatively be considered a cumulatively considerable contribution to a significant cumulative transportation impact.

3.9 TRIBAL CULTURAL RESOURCES

3.9.1 Environmental Setting
Traditional models of California’s prehistory hypothesize that the coastline was populated by Native Americans from the interior of North America during the end of the last Ice Age. The Takic or Numic Tradition is present mainly in the Los Angeles, Orange, and western Riverside Counties region. In Los Angeles, Orange, and western Riverside Counties, changes in material culture, burial practices, and subsistence focus at the beginning of the Late Prehistoric period are considered the result of a Takic migration to the coast from inland desert regions. Modern Gabrielino, Juaneño, and Luiseño in this region are considered the descendants of the prehistoric Uto-Aztecan, Takic-speaking populations that settled along the California coast during this period, or perhaps somewhat earlier (City of Corona 2019).

The City is located within the territory of the Gabrielino Native American group. Surrounding native groups include the Chumash and Tatataviam/Alliklik to the north, the Serrano to the east, and the Luiseño/Juaneño to the south. The Gabrielino group established large, permeant villages in the fertile lowlands along rivers and streams and in sheltered areas along the coast, stretching from the foothills of the San Gabriel Mountains to the Pacific Ocean (City of Corona 2019). The City is located northwest of the border of the traditional Juaneño territory which was surrounded by the Luiseño to the south, the Gabrielino to the north, and the Cahuilla to the west. The Juaneño resided in permanent, well-defined villages and associated seasonal camps (City of Corona 2019). The City is also situated southwest of the traditional Cahuilla territory, which encompasses a large area and was bordered by 11 other Native American groups. Evidence suggests that the Cahuilla migrated to southern California approximately 2,000 to 3,000 years ago, most likely from the southern Sierra Nevada ranges of east-central California with other related Takic-speaking groups. The Cahuilla settled in a territory that extended west to east from the present-day City of Riverside to the center portion of the Salton Sea in the Colorado Desert, and south to north from the San Jacinto Valley to the San Bernardino Mountains (City of Corona 2019).

The closest ethnographically documented village to the General Plan area is known as Paxangna. Some researchers state the village was located along the Temescal Creek, while others state the village was farther south (City of Corona 2019).

3.9.1.1 Regulatory Framework
Federal
Archaeological Resources Protection Act
The Archaeological Resources Protection Act of 1979 regulated the protection of archaeological resources and sites which are on Federal lands and Indian lands.

Native American Graves Protection and Repatriation Act
The Native American Graves Protection and Repatriation Act is a federal law passed in 1990 that provides a process for museums and federal agencies to return certain Native American cultural items, such as 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

State
Assembly Bill 52 (PRC Section 21084.2)
AB 52 establishes a formal consultation process for California tribes as part of CEQA and equates significant impacts on “tribal cultural resources” with significant environmental impacts (PRC Section 21084.2). AB 52 defines a “California Native American tribe” as a Native American tribe located in California that is on the contact list maintained by NAHC. AB 52 requires formal consultation with California Native American tribes prior to determining the level of environmental documentation if a tribe has requested to be informed of proposed projects by the lead agency. AB 52 also requires that consultation address project alternatives and mitigation measures for significant effects, if requested by the California Native American tribe, and that consultation be considered concluded when either of the parties agrees to measures to mitigate or avoid a significant effect, or the agency concludes that mutual agreement cannot be reached.

Under AB 52, such mitigation or avoidance measures must be recommended for inclusion in the environmental document and adopted mitigation monitoring program if determined to avoid or lessen a significant impact on a tribal cultural resource.

California Health and Safety Code and Public Resources Code Broad provisions for the protection of Native American cultural resources are contained in the HSC, Division 7, Part 2, Chapter 5 (Sections 8010 through 8030). Several provisions of the PRC also govern archaeological finds of human remains and associated objects. Procedures are detailed under PRC Section 5097.98 through 5097.996 for actions to be taken whenever Native American remains are discovered.

Section 7050.5 of the HSC states that any person who knowingly mutilates or disinters, wantonly disturbs, or willfully removes human remains in or from any location other than a dedicated cemetery without authority of law is guilty of a misdemeanor, except as provided in Section 5097.99 of the PRC. Any person removing human remains without authority of law or written permission of the person or persons having the right to control the remains under PRC Section 7100 has committed a public offense that is punishable by imprisonment. PRC Chapter 1.7, Section 5097.5/5097.9 (Stats. 1965, c. 1136, p. 2792), entitled Archaeological and Historical Sites, defines any unauthorized disturbance or removal of remains on public land as a misdemeanor.

SB 18
SB 18 requires cities and counties to consult with California Native American tribes during the local planning process for the purpose of protecting Traditional Tribal Cultural Places. This allows Native American tribes the opportunity to provide input with respect to the possible preservation of, or the mitigation of impacts on, specified Native American places, features, and objects located within that jurisdiction. This consultation is required prior to amending or adopting any general plan or specific plan or designating land as open space. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3.9.2 Impact Discussion

3.9.2.1 Thresholds of Significance
In accordance with the CEQA Guidelines Appendix G Environmental Checklist, the following question was analyzed and evaluated to determine whether impacts to tribal cultural resources are significant. Would the Project:
• Would the Project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:
o Listed or eligible for listing in the CRHR, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), or
o A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe?

3.9.2.2 Project Impacts
Would the Project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:

Listed or eligible for listing in the CRHR, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), or
A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe?
Finding: Same Impact as Approved Project (Less than Significant Impact with Mitigation) The City, as the CEQA Lead Agency, will consult with appropriate tribes with the potential for interest in the region. Based on this consultation, it will be identified if the proposed Project site is located in an area having the potential for tribal cultural resources. SB 18 states: “Prior to the adoption or any amendment of a general plan or specific plan, a local government must notify the appropriate tribes (on the contact list maintained by the NAHC) of the opportunity to conduct consultations for the purpose of preserving, or 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-86
mitigating impacts to, cultural places located on land within the local government’s jurisdiction that is affected by the proposed plan adoption or amendment. Tribes have 90 days from the date on which they receive notification to request consultation, unless a shorter timeframe has been agreed to by the tribe.” In accordance with AB 52 and SB 18, the City provided notice to the appropriate Native American Tribes on June 7, 2022, inviting them to participate and consult with the City through its AB 52 and SB 18 Native American outreach efforts. As included in Appendix C, response letters were received from the following organizations and tribes:
• Gabrieleno Band of Mission Indians – Kizh Nation
• Rincon Band of Luiseño Indians
• Native American Heritage Commission
The Gabrieleno Band of Mission Indians – Kish Nation requested consultation at the time of ground disturbance related to future Project implementation, and the Rincon Band of Luiseño Indians also did not request consultation at this time. The Native America Heritage Commission provided its general guidelines regarding tribal cultural resources but did not have specific Project-related requirements.

There was no substantial evidence provided related to the presence of a tribal cultural resource. In addition, as the proposed Project would not result in development, in and of itself, future implementing development projects would be required to analyze their project-specific impacts for conformance with the General Plan and all applicable regulations and requirements related to tribal cultural resources. Nevertheless, policies in the General Plan Update EIR were identified that would minimize potential impacts to tribal cultural resources from new development and/or redevelopment in the City, ground-disturbing activities related to future Project implementation which could potentially impact tribal cultural resources in the City and the SOI. As such, implementation of mitigation measures would be required to reduce the potential for future Project-related impacts to less than significant levels.

General Plan Update EIR Mitigation Measure CUL-5 would be applicable to the reduce impacts related to the development of future implementing Projects, as would General Plan Update EIR Mitigation Measures TCR-1, TCR-2 and TCR-3. With implementation of General Plan Updated EIR Mitigation Measures CUL5, TCR-1, TCR-2 and TCR-3, potential impacts to related to tribal cultural resources would be reduced to less than significant levels.

3.9.2.3 Cumulative Impacts
Would the Project result in a cumulatively considerable contribution to a significant cumulative tribal cultural resources impact?
Finding: Same Impact as Approved Project (Less than Significant Impact with Mitigation) The geographic area for cumulative impacts related to tribal cultural resources includes most of the City and its SOI. Although future implementing project development could include ground-disturbing activities 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-87
that may affect undiscovered tribal cultural resources, those projects and other cumulative projects would be required to confirm with all applicable regulations, standard permit conditions and mitigation measures to reduce potential impacts to tribal cultural resources and buried remains. Furthermore, future implementing projects and cumulative projects would be required to undertake tribal consultation pursuant to AB 52. Therefore, future Project implementation, in conjunction with the cumulative projects, would not result in a cumulatively considerable contribution to a cumulative tribal cultural resources impact.

3.9.2.4 Mitigation Measures
The following mitigation measures are required for the proposed project.

Mitigation Measure CUL-5. To determine the archaeological sensitivity for projects within the City, an archaeological resources assessment shall be performed under the supervision of an archaeologist that meets the Secretary of the Interior’s Professionally Qualified Standards (PQS) in either prehistoric or historic archaeology. The assessments shall include a California Historical Resources Information System (CHRIS) records search and a search of the Sacred Lands File (SLF) maintained by the Native American Heritage Commission (NAHC). The records searches shall determine if the proposed project has been previously surveyed for archaeological resources, identify and characterize the results of previous cultural resource surveys, and disclose any cultural resources that have been recorded and/or evaluated. A Phase I pedestrian survey shall be undertaken in areas that are undeveloped to locate any surface cultural materials.
a. If potentially significant archaeological resources are identified through an archaeological resources assessment, and impacts to these resources cannot be avoided, a Phase II Testing and Evaluation investigation shall be performed by an archaeologist who meets the PQS prior to any construction-related ground-disturbing activities to determine significance. If resources determined significant or unique through Phase II testing, and site avoidance is not possible, appropriate sitespecific mitigation measures shall be established and undertaken. These might include a Phase III data recovery program that would be implemented by a qualified archaeologist and shall be performed in accordance with the Office of Historic Preservation’s Archaeological Resource Management Reports (ARMR): Recommended Contents and Format (1990) and Guidelines for Archaeological Research Designs (1991).
b. If the archaeological assessment did not identify potentially significant archaeological resources within the proposed General Plan area but indicated the area to be highly sensitive for archaeological resources, a qualified archaeologist shall monitor all ground disturbing construction and pre-construction activities in areas with previously undisturbed soil. The archaeologist shall inform all construction personnel prior to construction activities of the proper procedures in the event of an archaeological discovery. The training shall be held in conjunction with the project’s initial on-site safety meeting, and shall explain the importance and legal basis for the protection of significant archaeological resources. In the event that archaeological resources (artifacts or features) are exposed during ground-disturbing activities, construction activities in the immediate vicinity of the discovery shall be halted while the resources are evaluated for significance by an 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Environmental Setting, Impacts and Mitigation
3-88
archaeologist who meets the PQS. If the discovery proves to be significant, it shall be curated with a recognized scientific or educational repository.
c. If the archaeological assessment did not identify potentially significant archaeological resources, but indicates the area to be of medium sensitivity for archaeological resources, an archaeologist who meets the PQS shall be retained on an on-call basis. The archaeologist shall inform all construction personnel prior to construction activities about the proper procedures in the event of an archaeological discovery. The training shall be held in conjunction with the project’s initial onsite safety meeting, and shall explain the importance and legal basis for the protection of significant archaeological resources. In the event that archaeological resources (artifacts or features) are exposed during ground disturbing activities, construction activities in the immediate vicinity of the discovery shall be halted while the on-call archaeologist is contacted. If the discovery proves to be significant, it shall be curated with a recognized scientific or educational repository.

Mitigation Measure TCR-1. Tribal Cultural Resources Monitoring. The project archaeologist, in consultation with interested tribes, the developer and the City of Corona, shall develop an Archaeological Monitoring Plan (AMP) to address the details, timing and responsibility of archaeological and cultural activities that will occur on the project site. Details in the AMP shall include:

1. Project-related ground disturbance (including, but not limited to, brush clearing, grading, trenching, etc.) and development scheduling;

2. The development of a rotating or simultaneous schedule in coordination with the developer and the project archeologist for designated Native American Tribal Monitors from the consulting tribes during grading, excavation and ground disturbing activities on the site: including the scheduling, safety requirements, duties, scope of work, and Native American Tribal Monitors’ authority to stop and redirect grading activities in coordination with all project archaeologists (if the tribes cannot come to an agreement on the rotating or simultaneous schedule of tribal monitoring, the Native American Heritage Commission shall designate the schedule for the onsite Native American Tribal Monitor for the proposed project);

Pursuant to the AMP, a tribal monitor from the consulting tribe (e.g., Pechanga Band of Luiseño Indians, Soboba Band of Luiseño Indians, or Gabrieleño Band of Mission Indians – Kizh Nation) shall be present during the initial grading activities. If tribal resources are found during grubbing activities, the tribal monitoring shall be present during site grading activities. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

3-89
Mitigation Measure TCR-2. Treatment and Disposition of Cultural Resources. In the event that Native American cultural resources are inadvertently discovered during the course of any ground disturbing activities, including but not limited to brush clearance, grading, trenching, etc. grading for the proposed project, the following procedures will be carried out for treatment and disposition of the discoveries:

2. Treatment and Final Disposition: The landowner(s) shall relinquish ownership of all cultural resources, including sacred items, burial goods, and all archaeological artifacts and non-human remains as part of the required mitigation for impacts to cultural resources. The applicant shall relinquish the artifacts through one or more of the following methods and provide the City of Corona with evidence of same:
a. Accommodate the process for onsite reburial of the discovered items with the consulting Native American tribes or bands. This shall include measures and provisions to protect the future reburial area from any future impacts. Reburial shall not occur until all cataloguing, basic analysis, and other analyses as recommended by the project archaeologist and approved by consulting tribes and basic recordation have been completed; all documentation should be at a level of standard professional practice to allow the writing of a report of professional quality; b. A curation agreement with an appropriate qualified repository within San Bernardino County that meets federal standards per 36 CFR Part 79 and therefore would be professionally curated and made available to other archaeologists/researchers for further study. The collections and associated records shall be transferred, including title, to an appropriate curation facility within San Bernardino County, to be accompanied by payment of the fees necessary for permanent curation;
c. For purposes of conflict resolution, if more than one Native American tribe or band is involved with the project and cannot come to an agreement as to the disposition of cultural materials, they shall be curated at the San Bernardino County Museum by default; d. At the completion of grading, excavation and ground disturbing activities on the site, a Phase IV Monitoring Report shall be submitted to the City documenting monitoring activities conducted by the project archaeologist and Native Tribal Monitors within 60 days of completion of grading. This report shall document the impacts to the known resources on the property; describe how each mitigation measure was fulfilled; document the type of cultural resources recovered and the disposition of such resources; provide evidence of the required cultural sensitivity training for the construction staff held during the required pre-grade meeting; and, in a confidential appendix, include the daily/weekly monitoring notes from the archaeologist. All reports produced will be submitted to the City, County Museum, and consulting tribes. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR

Growth-Inducing Impacts
4-1

4.0 GROWTH-INDUCING IMPACTS
Would the Project foster or stimulate significant economic or population growth in the surrounding environment?
The CEQA Guidelines require that an EIR identify the likelihood that a proposed project could “foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment” (Section 15126.2(d)). This section of the Draft SEIR is intended to evaluate the impacts of such growth in the surrounding environment. Examples of projects likely to have significant growth-inducing impacts include removing obstacle to population growth, for example by extending or expanding infrastructure beyond what is needed to serve the project. Other examples of growth inducement include increases in population that may tax existing service facilities, requiring construction of new facilities that could cause significant environmental effects.

The Project involves the rezoning of certain parcels within the City to high density residential. The rezone program will establish a new AHO zone that will allow the City to properly plan for housing sites to meet its state mandated RHNA allocation of low- and moderate-income units. The Project does not involve the actual development of specific parcels but does allow for the planning of higher density housing. The Project would amend the General Plan to ensure that the City’s projected and planned growth meets its RHNA allocation. The Project would result in more lands within the City being allocated for future residential development to accommodate projected population growth; however, the Project would be a part of the planned growth in the General Plan. Furthermore, the Project would not result in or require the expansion of utilities or roadways.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Significant and Irreversible Environmental Changes
5-1

5.0 SIGNIFICANT AND IRREVERSIBLE ENVIRONMENTAL

CHANGES
As mandated by the CEQA Guidelines, the EIR must address any significant irreversible environmental changes that would result from implementation of the proposed project. Specifically, pursuant to the CEQA Guidelines (Section 15126.2(c)), such an impact would occur if:
• The project would involve a large commitment of nonrenewable resources; • Land area committed to new project facilities;
• Irreversible damage can result from environmental accidents associated with the project; and • The proposed consumption of resources is not justified (e.g., the project results in the wasteful use of energy).

The Project involves the rezoning of certain parcels within the City to accommodate the planning of higher density residential development. The sites are infill and located in parts of the City that include existing developed parcels and public infrastructure. The AHO zone is an overlay to the zoning that already exists on the subject sites identified, which already allows for urban development. Additionally, some sites area already developed with existing buildings and utilities. If future residential development is proposed on the subject parcels identified, development would be required to adhere the City’s adopted development standards in the Corona Municipal Code, General Plan, California Building Standards and mitigation measures identified in the SEIR. Therefore, Project implementation would not result in land area being committed to new project facilities.

Project implementation would not result in a large commitment of nonrenewable resources or consumption of resources that is not justified. Additionally, the rezoning of the parcels would not result in any activities that could lead to irreversible damage resulting from environmental accidents. Project implementation would not result in new significant and irreversible environmental changes. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Significant and Unavoidable Impacts
6-1

6.0 SIGNIFICANT AND UNAVOIDABLE IMPACTS
A significant unavoidable impact is an impact that cannot be mitigated to a less than significant level if the Project is implemented as proposed. The following significant unavoidable impacts have been identified as a result of Project implementation:

Air Quality
• The Project would conflict with or obstruct implementation of the applicable air quality plan. • The Project would result in a cumulatively considerable net increase of any criteria pollutants for which the Project region is non-attainment under an applicable federal or state ambient air quality standard.
• The Project would expose sensitive receptors to substantial pollutant concentration. • The Project would result in a cumulatively considerable contribution to a significant cumulative air quality impact.

Greenhouse Gas Emissions
• The Project would generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment.
• The Project would result in a cumulatively considerable contribution to a significant cumulative greenhouse gas emission impact.

Transportation
• The Project would conflict with or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b).
• The Project would result in a cumulatively considerable contribution to a significant cumulative transportation impact.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-1

7.0 ALTERNATIVES
CEQA requires that an EIR identify and evaluate alternatives to a project as it is proposed. Two key provisions from the CEQA Guidelines pertaining to the discussion of alternatives are included below.

Section 15126.6(a). Consideration and Discussion of Alternatives to the Proposed Project.

Rather, it must consider a reasonable range of potentially feasible alternatives that will foster informed decision making and public participation. An EIR is not required to consider alternatives which are infeasible. The lead agency is responsible for selecting a range of project alternatives for examination and must publicly disclose its reasoning for selecting those alternatives. There is no ironclad rule governing the nature or scope of the alternatives to be discussed other than the rule of reason.

Section 15126.6(b). Purpose. Because an EIR must identify ways to mitigate or avoid the significant effects that a project may have on the environment (PRC Section 21002.1), the discussion of alternatives shall focus on alternatives to the project or its location which are capable of avoiding or substantially lessening any significant effects of the project, even if these alternatives would impede to some degree the attainment of the project objectives, or be more costly.

Other elements of the Guidelines discuss that alternatives should include enough information to allow a meaningful evaluation and comparison with the proposed project. The CEQA Guidelines state that if an alternative would cause one or more additional impacts, compared to the proposed project, the discussion should identify the additional impact, but in less detail than the significant effects of the proposed project.

The three critical factors to consider in selecting and evaluating alternatives are: 1) the significant impacts from the proposed project that could be reduced or avoided by the alternative, 2) consistency with the project’s objectives, and 3) the feasibility of the alternatives available. Each of these factors is discussed below.

7.1 PROJECT OBJECTIVES
A project’s statement of objectives describes the purpose of the project and the reasons for undertaking the project. While CEQA does not require that alternatives be capable of meeting all of the project objectives, their ability to meet most of the objectives is considered relevant to their consideration. The objectives of the Project are to:
• Implement the 2021-2029 Housing Element Programs to provide adequate housing sites for all income levels within the City.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-2
• Promote housing opportunities that support the City’s state mandated Regional Housing Needs Assessment.
• Promote fair housing opportunities that encourage access to lower- and moderate-income housing. • Promote safe and healthy housing opportunities to discourage overcrowding.

7.2 SIGNIFICANT IMPACTS FROM THE PROJECT
The CEQA Guidelines advise that the alternatives analysis in an EIR should be limited to alternatives that would avoid or substantially lessen any of the significant effects of a project and would achieve most of the project objectives.

Alternatives are discussed that could reduce the following identified significant and unavoidable impacts associated with Project implementation as proposed. Impacts that were determined to be significant and unavoidable include:

Noise
• The Project would result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-3
Transportation
• The Project would conflict with or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b).
• The Project would result in a cumulatively considerable contribution to a significant cumulative transportation impact.

Impacts that were determined to be significant but would be reduced to a less than significant level with mitigation include:

Noise
• The Project would generate excessive groundborne vibration or groundborne noise levels.

Tribal Cultural Resources
• The Project would cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:
a. Listed or eligible for listing in the CRHR, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), or
b. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.
• The Project would result in a cumulatively considerable contribution to a significant and cumulative tribal cultural resources impact.

7.3 PROJECT ALTERNATIVES
Pursuant to the CEQA Guidelines Section 15126.6(a):

An EIR shall describe a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project and evaluate the comparative merits of the alternatives. An EIR need not consider every conceivable alternative to a project. Rather it must consider a reasonable range of potentially feasible alternatives that will foster informed decision making and public participation.
11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-4
The City considered the following alternatives to the Project:
• No Project Alternative
• Reduced Density Alternative Up To 45 Dwelling Units per Acre • Alternate Development Areas Alternative

7.3.1 Alternatives Considered and Rejected
In accordance with CEQA Guidelines Section 15126.6(c), an EIR should identify alternatives that were considered for analysis but rejected as infeasible and briefly explain the reasons for their rejection.

According to the CEQA Guidelines, the following factors may be used to eliminate alternatives from detailed consideration: the alternative’s failure to meet most of the basic project objectives, the alternative’s infeasibility, or the alternative’s inability to avoid significant environmental impacts. Alternatives that have been considered and rejected as infeasible include:

7.3.1.1 Off-Site Alternative
As one of the primary objectives of the proposed Project is to promote housing opportunities that support the City’s state mandated RHNA, it would be impossible to meet this objective with an alternative that did not wholly focus on future residential development projects within the City itself. Therefore, this alternative was not analyzed further.

7.3.1.2 Reduced Density Alterative Up To 36 Dwelling Units per Acre A reduced density alternative that is the same as the City’s General Plan High Density Residential density of up to 36 dwelling units per acre would require more sites to be rezoned throughout the City, which would involve rezoning twice the amount of parcels identified in the Project. Although this alternative would meet the project objective of providing housing sites, the quantity of units to be developed at a given time will be reduced because of the density limitation. Additionally, finding sites suitable for residential development becomes limited because not all sites, especially non-vacant sites, will meet the criteria required by HCD to be counted as a suitable site in meeting the City’s RHNA. Therefore, the alternative was not analyzed further.

7.3.2 Alternatives Evaluated

7.3.2.1 Alternative 1: No Project Alternative
Under the No Project Alternative, the existing zoning designations of the identified parcels would be retained, and no rezoning program would take place. The No Project Alternative would not meet any of the project objectives and the City would not meet its RHNA allocation in the planning of low- and moderateincome housing sites. The City’s total RHNA allocation is 6,088 units with 3,888 allocated to low- and moderate-income housing units, consisting of 2,792 units and 1,096 units, respectively. The General Plan Update EIR anticipated an additional 5,494 residential units which results in a deficiency of 594 units from 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-5
the RHNA allocation. Therefore, the No Project Alternative would maintain the status quo of the General Plan Update and would not result in the City meeting its RHNA requirements in accordance with the Housing Element Update and achieving any of the project objectives to provide adequate housing sites for all income levels within the City, promote housing opportunities that support the City’s state mandated RHNA, promote fair housing opportunities that encourage access to lower and moderate income housing, and promote safe and healthy housing opportunities to discourage overcrowding.

Based on current General Plan growth forecasts, the No Project Alternative would have the same significant and unavoidable impacts to air quality, greenhouse gas, noise and transportation.

7.3.2.2 Alternative 2: Reduced Density Alternative Up To 45 Dwelling Units per Acre The Project proposes to apply an AHO zone at a maximum density of 60 dwelling units per acre to 100 sites to accommodate 4,651 additional housing units. The Reduced Density Alternative would reduce the maximum density on the AHO zone parcels to 45 dwelling units per acre. Alternative 2 would also reduce the number of residential units the AHO zone could accommodate to 3,492 dwelling units.

Under Alternative 2, vacant parcels (750 units) and nonvacant parcels (452 units) could accommodate a total of approximately 1,202 new housing units, and potential rezone parcels (368 units) and AHO parcels (3,492 units) at a maximum density of 45 units per acre would accommodate a total of approximately 5,062 additional housing units. As with the proposed Project, the majority of candidate rezoning sites would be located within a HQTA. Based on this, by implementing the Reduced Density Alternatives, the City would be able to accommodate the 2021-2029 RHNA and provide a RHNA-buffer of 4 percent for low-income households and a 1.5 percent buffer for moderate-income households.

Alternative 2 would meet all of the project objectives; however, an adequate buffer would not be provided, thereby putting the City at risk of reevaluating additional sites in the future should the subject sites be deemed unsuitable for any reason. While the severity of significant and unavoidable impacts related to air quality, greenhouse gas emissions, noise and transportation, including cumulative impacts, would be reduced as compared to the proposed Project, these impacts would not be reduced to a less than significant level, even with the incorporation of mitigation measures. Impacts related to vibration impacts and tribal cultural resources would be similar as compared to the proposed Project.

7.3.2.3 Alternative 3: Alternate Development Areas Alternative The Alternate Development Areas Alternative is consideration of different locations for redevelopment. A Citywide comprehensive land survey has been conducted, and the candidate sites have been selected in order to support the City’s objectives to sustainably increase residential density, especially in a transitoriented community. Consideration of alternative locations may take place in areas that are not well-suited for the intensified residential redevelopment, within a HQTA, or may not meet the criteria established by HCD for “non-vacant” sites to be considered as viable sites that would be repurposed for residential development. Development standards within transit-oriented communities aim to support the highest density for the proposed Project, as they are intended to encourage compact development, improve access 11 City of Corona General Plan Housing Element Rezoning Program Update Project Supplemental EIR
Alternatives
7-6
to transit, and promote a pedestrian-oriented environment. Transit-oriented community development standards would require a minimum of 60 units per acre, as provided by the proposed Project.

Alternative 3 would not meet most of the project objectives, as it would not implement the City’s 2021-2029 Housing Element Update Programs to provide housing sites for all income levels within the City, it would not promote housing opportunities that support the City’s state mandated Regional Housing Needs Assessment, and it would not promote fair housing opportunities that encourage access to lower- and moderate-income housing. Without the siting of residential development within a HQTA, impacts related to air quality, greenhouse gas emissions and transportation would be more severe than under the proposed Project, as housing would developed in less transit-oriented locations and would not provide alternative transportation options. Impacts related to vibration impacts and tribal cultural resources would be similar as compared to the proposed Project.

7.3.3 Environmentally Superior Alternative
CEQA Guidelines Section 15126.6(e)(2) state that an EIR shall identify an environmentally superior alternative. If the environmentally superior alternative is the “No Project” alternative, the EIR shall also identify an environmentally superior alternative among the other alternatives. Based on the above evaluation of Alternatives, Alternative 2, the Reduced Density Alternative, would be the environmentally superior alternative. It meets all of the project objects. While Alternative 2 would reduce the severity of significant and unavoidable impacts related to air quality, greenhouse gas emissions, noise and transportation as compared to the proposed Project, these impacts would remain significant and unavoidable.

City of Corona General Plan Housing Element Rezoning Program Update Project Initial Study
Introduction

1.6 PROJECT PURPOSE
In accordance with California Government Code Section 65584, projected housing needs for each city and county in the Southern California region are prepared by Southern California Association of Governments (SCAG) under a process known as the Regional Housing Needs Assessment (RHNA). The RHNA allocates regional housing needs by income level among member jurisdictions. California law established the planning period for the current RHNA from June 30, 2021, to October 15, 2029.

In addition to including goals, policies, and implementation programs regarding housing issues, housing elements must include an inventory or list of housing sites at sufficient densities to accommodate a specific number of units at various levels of affordability assigned to the City by SCAG. The Housing Element Update includes an inventory of properties that are intended to be rezoned to high density residential or an AHO zone in order to plan for low- and moderate-income units. The AHO zone is a new zoning designation that the City proposes to establish in order to create by-right development standards for affordable housing projects. The City also proposes to create development standards and architectural design guidelines for the AHO zone, which would cover existing properties that are developed with non-residential uses. The AHO zone would allow these properties to be redeveloped with residential land uses should a percentage of the housing units include low- and moderate-income housing.

1.6.1 Intended Uses of the Initial Study
This Initial Study (IS) is an informational document intended to inform the lead agency, other responsible or interested agencies, and the general public of potential environmental effects of the proposed Project.

The environmental review process has been established to enable public agencies to evaluate potential environmental consequences and to examine and implement methods of eliminating or reducing any potentially significant adverse impacts. This document is intended to aid the City in determining the appropriate California Environmental Quality Act (CEQA) document needed to support agency discretionary approvals, permits, and consultations.

2.0 PROJECT DESCRIPTION

2.1 PROPOSED AHO AND REZONING PROGRAM
The City’s General Plan was recently updated in 2020 and included adoption of the City of Corona General Plan Update Environmental Impact Report (General Plan Update EIR), a Programmatic EIR certified on June 30, 2020. As part of the General Plan Update effort, the City’s 2021-2029 Draft Housing Element Update was adopted by the City Council on November 3, 2021 and has been reviewed by the California Department of Housing and Community Development (HCD). The City is continuing to work with HCD on obtaining Housing Element compliance.

The General Plan Update EIR anticipated an additional 5,494 residential units; however, the RHNA allocation for the Housing Element Update now exceeds the City’s housing unit projection for Year 2040 in the General Plan Update. The City’s total RHNA allocation is 6,088 units with 3,888 allocated to low- and moderate-income housing units, consisting of 2,792 units and 1,096 units, respectively. Currently, the City’s RHNA allocation of 6,088 exceeds its projected housing growth by 594 units, in addition to accommodating an additional buffer.

As such, the City is now proposing a rezoning program to accommodate the planning of low- and moderateincome households as required by the state’s RHNA allocation for the City. These additional 594 housing units from the RHNA were not known at the time the General Plan Update EIR was prepared, potentially resulting in additional impacts that were not evaluated in the General Plan Update EIR. Therefore, supplemental environmental evaluation pursuant to CEQA is required to address the potential impacts from growth that could occur as a result of Project implementation.

The City’s Housing Element Update includes an inventory of properties that are intended to be rezoned to high density residential or an AHO zone in order to plan for potential sites to accommodate the RHNA allocation of units that would also be suitable for low- and moderate-income units. The AHO zone is a new zone being proposed by the City to establish by-right development standards for affordable housing projects. The AHO zone will cover existing properties that are currently developed with non-residential land uses. General Plan designations and zoning would remain, with overlays added, which would allow property owners to have the option to develop under either set of standards (the underlying General Plan and zoning or the AHO). The City is proposing to create development standards (i.e., criteria for building setbacks, parking, building height, landscaping, open space amenities, lot coverage, etc.) and architectural design guidelines for the AHO zone.

In addition to the RHNA allocation, a buffer is necessary to ensure that if one or more of the identified candidate sites are developed at lower densities or with non-housing uses, there would be remaining IJ

capacity to ensure an ongoing supply of sites for housing during the eight-year-cycle of the Housing Element. If there were no buffer provided, then the City could be obliged to identify new sites and amend the Housing Element if an identified site were developed with a non-housing project or developed at a density less than that anticipated in the Housing Element. The need for a substantial buffer is even more important during this cycle because of new rules in the Housing Accountability Act’s “no net loss” provisions.

Senate Bill (SB) 166 (2017) requires that the land inventory and site identification programs in the Housing Element always include sufficient sites to accommodate the unmet RHNA. This means that if a site identified in the Housing Element as having the potential to accommodate the lower‐income housing portion of the RHNA is actually developed for a higher income level, the locality must either: 1) identify and rezone, if necessary, an adequate substitute site; or 2) demonstrate that the land inventory already contains an adequate substitute site. Providing an adequate buffer is necessary to ensuring that the City remains compliant with the provisions of SB 166.

2.2.2 Candidate Sites
An important component of the City’s Housing Element Update is the identification of sites for future housing development, and an evaluation of the adequacy of those sites in fulfilling the City’s share of regional housing needs. To accomplish this, all City parcels were surveyed to determine their development capacity.

Due to the lack of vacant and underutilized sites in the City, candidate sites were selected for rezoning.

Each site was analyzed in light of the development standards for its proposed zoning designation. All parcels in the City were evaluated through a process of elimination based on required criteria set by HCD Candidate sites that are proposed for the AHO zone include a variety of uses on 100 parcels, including commercial, retail, industrial, surface parking, storage and vacant parcels, as described in Table 2 below.

In the proposed AHO zone, residential uses will be allowed on sites currently designated as MU2 on the General Plan. Sites in the MU1 zones are permitted to be entirely for residential use zone, if located in the proposed AHO zone. There are 57 parcels considered as potential sites for proposed rezoning, and these are primarily parcels that are currently used for residential uses, in addition to parking lots, mobile home parks and some commercial, institutional and vacant parcels, as described in Table 3 below. Current and proposed zoning are shown in Tables 2 and 3.

2.2.3 Surrounding Land Uses
As the existing land uses are comprised of a variety of land uses across the City, the surrounding land uses are similarly varied in character. They consist of residential development, vacant land, commercial and retail uses, parking lots, mobile home parks, institutional and industrial uses, as well as other urban and suburban land uses throughout the City.

As shown in Table 4 below, vacant parcels (750 units) and nonvacant parcels (452 units) can accommodate a total of approximately 1,202 new housing units, and potential rezone parcels (368 units) and AHO parcels (4,651 units) at a maximum density of 60 units per acre can accommodate a total of approximately 6,221 additional housing units. Based on this, by implementing the Project, the City would be able to accommodate the 2021-2029 RHNA and provide a RHNA-buffer of 39.5 percent for low-income households and 32 percent for moderate-income households.

3.0 ENVIRONMENTAL SETTING, ANALYSIS, AND

MITIGATION MEASURES

INTRODUCTION TO ENVIRONMENTAL ANALYSIS
As defined by Section 15063 of the State CEQA Guidelines, an Initial Study is prepared primarily to provide the Lead Agency with information to use as the basis for determining whether an Environmental Impact Report (EIR), Negative Declaration, or Mitigated Negative Declaration would be appropriate for providing the necessary environmental documentation and clearance for any proposed project. ☒ According to Section 15065, an EIR is deemed appropriate for a particular proposal if the following conditions occur:
• The proposal has the potential to substantially degrade quality of the environment. • The proposal has the potential to achieve short-term environmental goals to the disadvantage of long-term environmental goals.
• The proposal has possible environmental effects that are individually limited but cumulatively considerable.
• The proposal could cause direct or indirect adverse effects on human beings. ☐ According to Section 15070(a), a Negative Declaration is deemed appropriate if the proposal would not result in any significant effect on the environment.
☐ According to Section 15070(b), a Mitigated Negative Declaration is deemed appropriate if it is determined that though a proposal could result in a significant effect, mitigation measures are available to reduce these significant effects to insignificant levels.

This Initial Study has determined that the proposed applications will result in potentially significant environmental impacts and therefore, an Environmental Impact Report is deemed as the appropriate document to provide necessary environmental evaluations and clearance for the proposed Project.

This Initial Study and Notice of Preparation (NOP) are prepared in conformance with the California Environmental Quality Act of 1970, as amended (Public Resources Code [PRC], Section 21000 et. seq.); Section 15070 of the State Guidelines for Implementation of the California Environmental Quality Act of 1970, as amended (California Code of Regulations [CCR], Title 14, Chapter 3, Section 15000, et. seq.); applicable requirements of the City; and the regulations, requirements, and procedures of any other responsible public agency or an agency with jurisdiction by law.

The City is the Lead Agency, in accordance with Section 15050 of the CEQA Guidelines. The Lead Agency is the public agency which has the principal responsibility for approving the necessary environmental clearances and analyses for any project in the County.

IJ
City of Corona General Plan Housing Element Rezoning Program Update Project Initial Study
Environmental Setting, Analysis, and Mitigation Measures 3-2
Intended Uses of Initial Study and Notice of Preparation This IS and Notice of Preparation (NOP) are informational documents which are intended to inform decision makers, other responsible or interested agencies, and the general public of potential environmental effects of the proposed applications. The environmental review process has been established to enable public agencies to evaluate environmental consequences and to examine and implement methods of eliminating or reducing any potentially adverse impacts. While CEQA requires that consideration be given to avoiding environmental damage, the Lead Agency and other responsible public agencies must balance adverse environmental effects against other public objectives, including economic and social goals. The IS and NOP prepared for the Project will be circulated for a period of 30 days for public and agency review and comments.

Environmental Assessment Methodology
The environmental factors checked below would be potentially affected by this Project, involving at least one impact that requires mitigation to reduce the impact from “Potentially Significant” to “Less than Significant” as indicated by the checklist on the following pages. ☐ Aesthetics ☒ Greenhouse Gases ☒ Public Services
☐ Agricultural and Forestry

☒ Transportation
☒ Biological Resources ☒ Land Use and Planning ☒ Tribal Cultural Resources ☒ Cultural Resources ☒ Mineral Resources ☐ Utilities and Service Systems ☒ Energy Resources ☒ Noise ☐ Wildfires
☒ Geology and Soils ☐ Population and Housing ☒ Mandatory Findings of Significance Evaluation of Environmental Impacts
Section 3.0, Environmental Checklist and Environmental Evaluation presents the environmental checklist form found in Appendix G of the CEQA Guidelines. The checklist form is used to describe the impacts of the Project. A discussion follows each environmental issue identified in the checklist. Included in each discussion are project-specific mitigation measures, if needed.

For the checklist, the following designations are used:

Potentially Significant Impact: An impact that could be significant and for which mitigation has not been identified. If any potentially significant impacts are identified, an EIR must be prepared. An Initial Study Mitigated Negative Declaration (ISMND) cannot be used if there are potentially significant impacts that cannot be mitigated.

Less Than Significant with Mitigation Incorporated: This designation applies when applicable and feasible mitigation measures previously identified in prior applicable EIRs or in the General Plan Update Environmental Impact Report (General Plan Update EIR) have reduced an effect from “Potentially City of Corona General Plan Housing Element Rezoning Program Update Project Initial Study
Environmental Setting, Analysis, and Mitigation Measures 3-3
Significant Impact” to a “Less Than Significant Impact” and, pursuant to Section 21155.2 of the PRC, those measures are incorporated into the ISMND.

This designation also applies when the incorporation of new project-specific mitigation measures not previously identified in prior applicable EIRs or in the General Plan Update EIR have reduced an effect from a “Potentially Significant Impact” to a “Less Than Significant Impact”.

Less Than Significant Impact: Any impact that would not be considered significant under CEQA, relative to existing standards.

No Impact: The proposed Project would not have any impact.

Important Note to the Reader
The California Supreme Court in a December 2015 opinion [California Building Industry Association v. Bay Area Air Quality Management District, 62 Cal. 4th 369 (No. S 213478)] confirmed that CEQA, with several specific exceptions, is concerned with the impacts of a project on the environment, not the effects the existing environment may have on a project. Therefore, the evaluation of the significance of project impacts under CEQA in the following sections focuses on impacts of the Project on the environment, including whether a Project may exacerbate existing environmental hazards.

This is consistent with one of the primary objectives of CEQA and this document, which is to provide objective information to decision‐makers and the public regarding the proposed Project as a whole. The CEQA Guidelines and the courts are clear that a CEQA document (e.g., EIR or IS) can include information of interest even if such information is not an “environmental impact” as defined by CEQA.

3.1.1 Environmental Setting
As described in the General Plan Update EIR, visual resources in the City include scenic mountain views, scenic city views, prominent scenic vistas and scenic corridors. As the Project implementation would result in future development and more dense residential uses, potential impacts to aesthetics are evaluated below.

3.1.2 Environmental Impact Analysis
a) Would the project have a substantial adverse effect on a scenic vista? Finding: Less than Significant Impact
Scenic vistas generally include extensive panoramic views of natural features, unusual terrain, or unique urban or historic features, for which the field of view can be wide and extend into the distance, and focal views that focus on a particular object, scene or feature of interest. According to the City’s General Plan Update EIR, scenic vistas include Chino Hills State Park and Prado Basin to the northwest, San Bernardino Mountains to the North, Cleveland National Forest to the West, Santa Ana Mountains to the south, and the Gavilan Hills to the east. Mountain vistas and views of the Prado Basin are available from all parts of the City and are prominent from within most viewsheds. More rural, open space areas in the far southern and eastern parts of the City provide views of other scenic and natural resources. City views are also available the many ridges and peaks surrounding the City (City of Corona 2019). □ □ ~ □

Implementation of the overall development proposed in the General Plan Update EIR and the related Housing Element Update would allow for currently undeveloped parcels to be developed, as well as permitting the intensification of existing land uses throughout the City, including along publicly available areas which currently provide scenic vistas. The proposed Project is a rezoning program to accommodate the planning of low- and moderate-income households, including an AHO zone and an increase of approximately 2,415 dwelling units, which includes the city’s minimum RHNA allocation for low and moderate-income units and a buffer using a maximum density of 60 du/ac in the AHO zone. As with General Plan implementation, Project implementation, including the increased residential density, would not have a substantial adverse effect on scenic vistas, as the Project would continue to preserve open space areas, parks, and agricultural lands that provide views of scenic vistas and resources.

Furthermore, the General Plan includes goals and policies related to the preservation of scenic vistas in the City. General Plan Goal CD-6 includes the development of land use controls that preserve significant visual resources from potential loss or disruption. As Project implementation would be consistent with the City’s General Plan, future development within the City would be required to adhere to the City’s General Plan, including applicable design standards and municipal goal requirements. Therefore, future residential development resulting from Project implementation would not adversely impact vistas and scenic resources in and around the City, and impacts would be less than significant. This topic does not require further evaluation in an EIR.
b) Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Finding: Less than Significant Impact
The State Scenic Highway Program, which is administered by the California Department of Transportation (Caltrans), identifies designated scenic highways across the state. As identified in the General Plan Update EIR, there are no officially designated state scenic highways in the City; however, portions of some highways are considered eligible for designation as a state scenic highway, including portions of State Route (SR) 72, Interstate 15, and SR 91, west of the Interstate 15 interchange (City of Corona 2019). The closest officially designated state scenic highway is SR 91 in Orange County, west of its intersection with SR 55.

The City’s General Plan update identified the three state-eligible scenic highways and six additional locally designated highways as City scenic corridors. According to the General Plan Update EIR, the mix of land uses near these identified roadways is varied and includes residential, commercial, office, industrial and other urban/suburban uses. The Project’s proposed rezoning program would result in increased density and intensity of uses in many areas of the City; however, adherence to the General Plan, including Goal CD-7 to maintain, establish, develop and protect the City’s highways and corridors for scenic purposes, would continue to preserve corridors that currently provide views of scenic vistas. As such, future residential development resulting from Project implementation would not substantially damage scenic resources from within a state scenic highway, either designated or eligible, and impacts would be less than significant. This topic does not require further evaluation in an EIR.

c) In non-urbanized areas, would the project substantially degrade the existing visual character or quality of public views of the site and its surroundings. (Public Views are those that are experienced from a publicly accessible vantage point). If the Project is in an urbanized area, the potential of the project to conflict with applicable zoning and other regulations governing scenic quality?
Finding: Less than Significant Impact
Future residential development associated with Project implementation would be located in an urbanized area; however, portions of these future Project could affect areas along the City’s wildland-urban interface.

As required by the General Plan, the Community Design Element includes goals and policies that are implemented through more detailed residential and non-residential design guidelines and specifications.

Therefore, all development in the City, including that which would occur as a result of Project implementation, would be required to comply with existing regulations relating to the maintenance of the City’s character, including development design guidelines which encourage the City’s goals and objectives to provide for well-designed and attractive development intended to promote a sense of community.

Provisions of the City’s Zoning Ordinance (City Municipal Code Title 17) are applicable to the development and use of property through the implementation of development standards intended to preserve visual resources and maintain the aesthetic appearance of residential neighborhoods and non-residential properties and corridors (City of Corona 2019). As the proposed Project would be implemented in accordance with the City’s General Plan, Zoning Ordinance and all applicable regulations, the increased residential density associated with Project implementation would not conflict with applicable zoning and other regulations governing scenic quality. Therefore, impacts would be less than significant, and this topic does not require further evaluation in an EIR.
d) Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?
Finding: Less than Significant Impact
Typical current sources of light and glare throughout the City include interior and exterior building lighting, illuminated signage, ballfield lighting, lighting from vehicles along existing roadways, and other ambient lighting present in urbanized settings. Sources of glare include glass or metallic surfaces or finishes, on structures and even off of vehicle windshields, that could cause glare effects. Some of the more suburban, lower density, open space or rural residential areas of the City have less sources of illumination, lighting and glare, particularly those areas adjacent to the Cleveland National Forest (City of Corona 2019). As with the General Plan, implementation of the proposed Project would occur in areas designated for development and would allow for development of currently underutilized and undeveloped parcels in the City. While the increased residential density associated with Project implementation would likely introduce new sources of light and glare the their immediate surroundings, all new development would be required to comply City guidelines and Municipal Code requirements, including Chapter 17.76 (directing lighting in parking areas designed to minimize the effects of spillover lighting) and Chapter 17.86 (requiring exterior lighting to be IJ
City of Corona General Plan Housing Element Rezoning Program Update Project Initial Study
Environmental Setting, Analysis, and Mitigation Measures 3-7
directed downward to minimize spillover lighting on adjacent properties, sensitive uses and open space areas).

In addition, the General Plan includes specific policies to minimize the impacts of light and glare, including Policy LU 11.12 (design of commercial projects abutting residential uses), Policy HC-2.4 (ensuring that the potential for lighting and glare impacts are understood when development is proposed), and Policy HC-2.6 (enforcement of performance standards with respect to glare). As future residential development resulting from Project implementation would adhere to the provisions of the General Plan, Municipal Code, and all other applicable regulations related to light and glare, the increased residential density proposed by the Project would not create substantial new sources of light or glare which would adversely affect views in the area. Therefore, this impact would be less than significant, and this topic does not require further evaluation in an EIR.
