To: Mayor and City Council
From: City Manager
Meeting Date: August 1, 2023
Subject: PUBLIC HEARING – ZONE RECLASSIFICATION NO. 328, ZONE CODE AMENDMENT NO.190 AND ADDENDUM TO

A MITIGATED NEGATIVE DECLARATION
Recommendation:

1. Approve a resolution and introduce an ordinance approving Zone Reclassification No. 328 to apply an R-40 Overlay Zone to the housing element sites;

2. Approve a resolution and introduce an ordinance approving Zone Code Amendment No. 190; and

3. Approve an Addendum to the Mitigated Negative Declaration.

Fiscal Impact:

There is no fiscal impact to the General Fund.

Background:

Since 1969, Housing Elements have been required components of local general plans in California. This is because the state legislature recognizes that ensuring housing for all Californians is crucial on a statewide level. A Housing Element is a comprehensive report that analyzes the housing needs of a community across all income levels. It also outlines strategies to effectively address and meet those housing needs.

In March 2021, the Southern California Association of Governments (SCAG) adopted its 6th cycle of the Regional Housing Needs Allocation (RHNA) plan, which covers the planning period from October 2021 through October 2029. In the 6th cycle, SCAG received a request for 1,341,827 housing units, which were then distributed among all 197 jurisdictions within.

Page 2 of 5 ends

The plan allocated the following housing unit types for the City of Pico Rivera:

Housing Needs for 2021-2029
Income Category (% of County AMI) Number of Units Percent Very Low (31 to 50%) 299 29.1%
Low (51 to 80%) 146 14.3%
Moderate (81% to 120%) 149 14.6%
Above Moderate (Over 120%) 430 42.0%
Total 1,024 100.0%
On September 27, 2022, the City Council adopted the 6th Cycle Housing Element for the City of Pico Rivera with goals, policies, and programs that will ensure the City meets the RHNA allocation plan. Additionally, it has been identified that there are 69 parcels within the City that are suitable and zoned for development according to the allocation plan (Attachment A). The proposed Zone Reclassification No. 328 will apply an R-40 overlay zone (density up to 40 dwelling units per acre) to the 69 parcels thereby increasing their currently permissible density and allow for the potential development of the allocation plan consisting of 1,024 housing units as noted above.

To address the housing shortage, recent State legislation, including Senate Bill (SB) 35 and SB 330, requires residential projects to be reviewed against objective standards.

Objective standards include a broad set of standards used by an agency to regulate development, including “objective zoning standards,” “objective subdivision standards,” and “objective design review standards.” Objective standards are the only basis a local agency may use to deny or reduce the density of certain eligible residential projects. Zone Code Amendment No. 190 establishes a basis for objective design standards for the City to utilize in reviewing residential development proposals.

Discussion:

R-40 Overlay Zone
The proposed R-40 Overlay Zone will be applied to 69 parcels whose current zoning classification range from Residential to Industrial. The R-40 Overlay Zone will not change the existing underlying zoning but will provide a higher density allowance of up to 40 units per acre for development proposals that include an affordable housing component.

Those development proposals that include an affordable housing component will also be able to take advantage of a streamlined ministerial application process. This means that these applications will be reviewed by City staff only and forgo a discretionary Planning Commission review through a typical Conditional Use Permit application. The streamlined application process, however, will be subject to objective design standards.

Objective Design Standards
Senate Bill (SB) 35 went into effect on January 1, 2018, and it requires cities and counties where housing production has not matched the Housing Element targets to use a streamlined, ministerial review process for qualifying multifamily residential projects.

Ministerial review is based on compliance with set, objective standards and cannot involve subjective judgment and or discretionary approval. Qualifying projects are also not subject to environmental review under the California Environmental Quality Act.

Senate Bill (SB) 330 went into effect on January 1, 2020 (subsequently extended), and it provides that a qualifying housing development project is only subject to the ordinances, policies, and standards adopted and in effect when a “preliminary application” is submitted, which occurs at the outset of the entitlements process. Development impact fees, charges, or other monetary exactions are also vested at that same time. In addition, it also prohibits agencies from holding more than five hearings/public meetings concerning residential projects and prohibits adoption zoning or General Plan policies that lessen the intensity of housing.

Objective design standards are intended to make the requirements that apply to certain eligible residential projects more predictable and easier to interpret for all stakeholders, including decision makers, staff, applicants, and members of the public. The purpose of objective design standards is for applicants to know beforehand what requirements apply to a proposed development and for the applicant to be able to design a project that meets those requirements before submittal. Objective design standards are defined in Government Code Sections 65913.4 and 66300(a)(7) as standards that:
“involve no personal or subjective judgment by a public official and are uniformly verifiable by reference to an external and uniform benchmark or criterion available and knowable by both the development applicant or proponent and the public official before submittal.”
Objective design standards may include portions of general plans, specific plans, zoning codes, overlay zones, subdivision requirements, and landscaping and other land development regulations.

The proposed objective design standards are in keeping with State allowances and will allow the City to effectively guide residential development and address items such as site design, building mass, articulation, lighting, open space, and similar design characteristics.

Planning Commission Recommendation
On June 5, 2023, the Planning Commission held a public hearing and recommended that the City Council approve Zone Reclassification No. 328, Zone Code Amendment No. 190 and an Addendum to a Mitigated Negative Declaration.

Environmental Analysis:

In consultation with the City, Rincon Consultants, Inc. prepared a Mitigated Negative Declaration Addendum to the previously adopted Housing Element IS-MND. Pursuant to the provisions of the California Environmental Quality Act (CEQA) Guidelines, Section 15164, a Lead Agency shall prepare an Addendum to an EIR or IS-MND if some changes or additions are necessary that will not have significant new impacts or substantially increase previously identified significant impacts. Specifically, the CEQA Guidelines state:
• The lead agency or responsible agency shall prepare an addendum to a previously certified EIR or adopted negative declaration if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred (Section 15164(a)); • An addendum need not be circulated for public review but can be included in or attached to the final EIR or adopted negative declaration (Section 15164€); • The decision-making body shall consider the addendum with the final EIR or adopted negative declaration prior to making a decision on the project (Section 15164(d)); and
• A brief explanation of the decision not to prepare a subsequent EIR or negative declaration pursuant to Section 15162 should be included in an addendum to an EIR or negative declaration, the lead agency’s findings on the project, or elsewhere in the record. The explanation must be supported by substantial evidence (Section 15164(e)).

In compliance with applicable requirements of the California Environmental Quality Act of 1970 (as amended) and the CEQA Guidelines, an Addendum to the previously adopted 2021-2029 Housing Element MND has been produced.

According to Section 15164 of the CEQA Guidelines, an addendum to a previously certified EIR or Negative Declaration is the appropriate environmental document in instances when “only minor technical changes or additions are necessary” and when the new information does not involve new significant environmental effects beyond those identified in the previous MND.

Conclusion:

Staff recommends that the City Council approve the enclosed resolutions approving Zone Reclassification No. 328, Zone Code Amendment No. 190, introduce the first readings of ordinances, and approve an Addendum to a Mitigated Negative Declaration.

Introduction
Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 1 1 Introduction
This document is an Addendum to the Pico Rivera 6th Cycle Housing Element Update Initial Study – Mitigated Negative Declaration (IS-MND). This Addendum has been prepared in accordance with relevant provisions of the California Environmental Quality Act (CEQA) of 1970 (as amended) and the CEQA Guidelines.

In accordance with Section 15164 of the CEQA Guidelines, a lead agency shall prepare an addendum to an adopted negative declaration as the appropriate environmental document in instances when “only minor changes or additions are necessary” that will not have significant new impacts or substantially increase previously identified significant impacts. Specifically, Section 15164 of the CEQA Guidelines states:
 An addendum to an adopted negative declaration may be prepared if only minor technical changes or additions are necessary or none of the conditions described in Section 15162 calling for preparation of a subsequent Environmental Impact Report (EIR) or negative declaration have occurred (Section 15164(b));
 An addendum need not be circulated for public review but can be included in or attached to the final EIR or adopted negative declaration (Section 15164(c));  The decision-making body shall consider the addendum with the final EIR or adopted negative declaration prior to making a decision on the project (Section 15164(d)); and  A brief explanation of the decision not to prepare a subsequent EIR or negative declaration pursuant to Section 15162 should be included in an addendum to an EIR or negative declaration, the lead agency's findings on the project, or elsewhere in the record. The explanation must be supported by substantial evidence (Section 15164(e)).

This Addendum describes the details of the proposed Zone Code Amendments and Zone Reclassification (herein referred to as “proposed Zone Amendments and Reclassification” or “proposed Project”) and compares project impacts to those identified in the final IS-MND adopted by City of Pico Rivera in 2022 for the Pico Rivera 6th Cycle Housing Element Update (herein referred to as “approved Housing Element Update”). Specifically, Section 2, Background, contains a description of the approved Housing Element Update and proposed Zone Amendments and Reclassification, whereas the analysis in Section 4, Environmental Checklist and Impacts of the Proposed Project, demonstrates that the proposed Project would not result in any new significant environmental impacts or any substantial increase in the severity of previously identified significant environmental impacts compared to the approved Housing Element Update. Consequently, this Addendum is the appropriate environmental document for the proposed Zone Amendments and Reclassification under CEQA.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
2 2 Background
The final IS-MND for the Pico Rivera 6th Cycle Housing Element Update (State Clearinghouse [SCH]#2021120397; “approved Housing Element Update”) was adopted in September 2022 and is herein referred to as “2022 IS-MND”. The approved Housing Element Update includes the City’s Housing Policy Plan for the 2021-2029 6th Cycle planning period, which in turn includes goals, policies, and programs concerning housing and housing-related services, as well as the City’s approach to addressing its share of the regional housing need. The 2022 IS-MND provides an analysis of the potential environmental impacts resulting from implementation of the Housing Element Update, including the General Plan Amendment for adoption of the Housing Element Update into the City’s General Plan. No other entitlements, including zone code changes, were proposed as part of the Housing Element Update analyzed in the 2022 IS-MND. Information and technical analyses from the 2022 IS-MND are utilized and/or referenced throughout this Addendum.

The City of Pico Rivera now proposes zone code changes in the form of a new overlay zone and objective design standards (“proposed Zone Amendments and Reclassification” or “proposed Project”) to further implement the approved Housing Element Update since adoption of the 2022 ISMND. This section provides an overview of the previously approved Housing Element Update, the accompanying 2022 IS-MND, and the proposed Zone Amendments and Reclassification to provide context for this Addendum prior to evaluating the potential environmental impacts of the proposed Project.

2.1 Previously Approved Housing Element Update
The City approved the Pico Rivera 6th Cycle Housing Element Update on September 27, 2022. For the 2021-2029 6th Cycle planning period, the Southern California Association of Governments (SCAG) identified a regional housing needs assessment (RHNA) allocation of 1,024 units. To meet the City’s RHNA allocation, the approved Housing Element Update identified 69 candidate housing sites covering 91.7 acres in the city, which were determined by the City to be available to accommodate the City’s RHNA allocation by income level. Figure 1 shows the regional location of the city and shows the location of the 69 candidate sites within the city. Table 1 shows the breakdown of the City’s RHNA by four income categories: very low income, low income, moderate income, and above moderate income.

Background
Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 5 As shown in Table 1, the City’s RHNA allocation for lower-income housing is 445 housing units, including 299 very-low-income housing units and 146 low-income housing units. The City has identified several sites currently located on non-residentially zoned parcels that could accommodate lower-income housing. The City’s General Commercial Zone and Special Commercial Zone allow for development of housing in a mixed-use setting at a density of 20 dwelling units per acre (du/ac). In addition, affordable units can be accommodated through accessory dwelling unit (ADU) development throughout the city. The City’s RHNA allocation for moderate-income housing is 579 housing units, including 149 moderate-income housing units and 430 above-moderate-income housing units. The City anticipates growth to meet the moderate- and above-moderate- income need from existing residentially and commercially zoned parcels (that presently permit residential development as a primary use) through the development of new units and through the development of ADUs and junior accessory dwelling units (JADUs) (Pico Rivera 2021).

The approved Housing Element Update does not directly propose new residential or other development on any of the 69 candidate housing sites identified in the Housing Element Update; rather, it demonstrates capacity for future development consistent with State law. Nonetheless, the 2022 IS-MND evaluated potential environmental impacts associated with implementation of the Housing Element Update and identified mitigation measures to reduce significant environmental impacts to a less-than-significant level. The 2022 IS-MND assumed project buildout by 2029 to meet the City’s RHNA allocation of 1,024 housing units and analyzed a potential development capacity of 1,332 housing units, which includes a 30 percent buffer atop the original RHNA allocation. The 2022 IS-MND also acknowledges that an additional 400 ADUs are proposed throughout the city (Pico Rivera 2021). The following is a summary of the overall goals identified by the City for the approved Housing Element Update (Pico Rivera 2021):

Preservation and Improvement of existing housing stock and neighborhoods; Access to opportunities for affordable housing;
Adequate supply and of housing and identification of resources for households with special needs;
Identification of adequate sites to meet the existing and future housing needs of the City at all income levels;
Evaluation of governmental constraints; and
Fair housing opportunities for all segments of the community, regardless of age, race, religion, sex, marital status, sexual orientation, ancestry, national origin, or disability.

2.2 Proposed Zone Amendments and Reclassification
The 2022 IS-MND assumed that future housing on the 69 candidate housing sites would be developed to have greater density than assumed in the City’s General Plan and SCAG growth projections. To meet the RHNA allocation for the 6th Cycle planning period, the proposed Zone Amendments and Reclassification involves the creation of the new R-40 Overlay Zone to apply to the 69 candidate sites, which would allow a density of up to 40 du/ac. The proposed Zone Amendments and Reclassification does not change the number or location of any candidate sites in the city. Furthermore, the R-40 Overlay Zone would be in addition to the existing zoning and would not change the existing underlying zoning. Property owners would still have the ability to exercise the development standards associated with their existing zone. The intent of the R-40 Overlay Zone City of Pico Rivera
Zone Code Amendments and Zone Reclassification
6 is to provide property owners and developers with additional options should they seek to develop affordable housing units. Table 2 shows the breakdown of the sites by income category identified to accommodate the 1,732 housing units, including a potential development capacity of 1,332 housing units from the R-40 Overlay Zone and an additional 400 ADUs in single-family residential areas.

To incentivize development, the State requires that a streamlined process occur for affordable housing units that were identified in the approved Housing Element Cycle. As such, through the use of the R-40 Overlay Zone, a Conditional Use Permit will not be required for developers wishing to develop affordable housing units within the 69 candidate sites. As part of the proposed Project, the City has also prepared objective design standards which developers would have to meet to utilize the streamlined process per Senate Bill (SB) 35. The objective design standards would be applicable to any by-right residential or mixed-use project qualifying for a streamlined, ministerial approval (no matter its location within the city), and would address items such as (but not limited to) site design, building mass, lighting, and open space.

Decision Not to Prepare a Subsequent EIR or MND
Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 7 3 Decision Not to Prepare a Subsequent EIR
or MND
As outlined in Section 15164(b) of the CEQA Guidelines, a lead agency shall prepare an addendum to an adopted negative declaration if only minor technical changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR or negative declaration have occurred.

As discussed in the following impact analysis, the technical changes and additions associated with the proposed Zone Amendments and Reclassification would not introduce new significant environmental impacts beyond those that have already been identified and characterized in the 2022 IS-MND for the approved Housing Element Update. None of the conditions described in Section 15162 of the CEQA Guidelines calling for preparation of a subsequent EIR or MND have occurred or would occur as a result of the proposed Project. Therefore, this Addendum to the adopted 2022 IS-MND for the approved Housing Element Update is consistent with CEQA, and is the appropriate level of environmental documentation to provide under CEQA. This Addendum will be considered by the City of Pico Rivera decision-making body in making a determination on the proposed Zone Amendments and Reclassification.

8 4 Environmental Checklist and Impacts of
the Proposed Zone Amendments and
Reclassification
This Addendum evaluates potential environmental impacts that could result from the proposed Zone Amendments and Reclassification. The existing environmental conditions throughout the city, and within the 69 candidate housing sites, are substantially the same under present conditions as described in the approved Housing Element Update. Nonetheless, the analysis below provides updates where necessary to characterize potential impacts associated with the proposed Project.

Appendix G of the CEQA Guidelines provides a checklist of environmental issues areas that are suggested as the issue areas that should be assessed in CEQA analyses. Consistent with the impacts analyses included in the 2022 IS-MND for the approved Housing Element Update, this Addendum addresses all 20 environmental issue areas included in Appendix G of the CEQA Guidelines, as listed:

1. Aesthetics

2. Agriculture and Forestry Resources

3. Air Quality

4. Biological Resources

5. Cultural Resources

6. Energy

The 2022 IS-MND assumed project buildout by 2029 to meet the City’s RHNA allocation of 1,024 housing units and analyzed a potential development capacity of 1,332 housing units, which includes a 30 percent buffer atop the original RHNA allocation. Potential environmental impacts of the proposed Zone Amendments and Reclassification are analyzed to determine whether impacts are consistent with the impact analysis provided in the 2022 IS-MND for the approved Housing Element Update, and whether additional mitigation measures are required to minimize or avoid potential impacts. Where impacts are identified in the following analysis, discussion of existing applicable regulations and identified mitigation measures from the 2022 IS-MND are included as relevant to the avoidance of potential impacts from the proposed Project. As discussed in Section 2.2, Proposed Zone Amendments and Reclassification, the City assumed a potential development capacity of 1,332 housing units in the 69 candidate housing sites from the R-40 Overlay Zone and an additional 400 ADUs in single-family residential areas. While the 2022 IS-MND also acknowledges that an additional 400 ADUs would be developed atop the 1,332 housing units, it does not analyze a full buildout of 1,732 housing units. Therefore, the analysis in this Addendum evaluates impacts associated with the development of an additional 400 ADUs for a total of 1,732 housing units under the proposed Project.

4.1 Aesthetics
As discussed in Section 4.1, Aesthetics, of the 2022 IS-MND , aesthetic impacts from implementation of the 2022 approved Housing Element Update would be less than significant with mitigation required. The proposed Project would not result in direct housing construction but would facilitate and provide a policy framework for future housing development throughout the City. The City of Pico Rivera General Plan (General Plan) does not identify any scenic vistas in the City. There are no State- or County-designated scenic highways in or near the City. The Arroyo Seco Historic Parkway Scenic Byway (federal byway) is approximately nine miles northwest of the City’s northwestern boundary. Because there are no State- or County-designated scenic highways in or proximate to the City, similar to the approved Housing Element Update, housing development under the proposed Project would not damage scenic resources and there would be no impact associated with scenic vistas and scenic highways.

Future housing development under the approved Housing Element Update would require consistency with General Plan policies and compliance with Pico Rivera Municipal Code (Municipal Code) standards, which would be verified through the City’s development review process, and therefore, would not conflict with zoning or regulations governing scenic quality. Further, future housing development would be required to comply with Measure SC AES-1, which requires applicants to provide a lighting and photometric plan demonstrating that there shall not be any light spillage to nearby residential properties. Considering these requirements and the City’s standard conditions, future housing development facilitated by the Housing Element Update would not create new sources of substantial light or glare. Therefore, impacts would be less than significant with mitigation incorporated.

Similar to the approved Housing Element Update, the proposed Project would be required to comply with Measure SC AES-1, which requires applicants to provide a lighting and photometric plan demonstrating that there shall not be any light spillage to nearby residential properties, in order to reduce impacts regarding light and glare. Any development resulting from the proposed Zone Amendments and Reclassification would be subject to these detailed design and development standards, similar to the approved Housing Element Update, and thus, the proposed Project would result in no new impacts related to aesthetics or impacts that would be substantially more severe than those discussed in the 2022 IS-MND for the approved Housing Element Update.

Measure SC AES-1: The applicant shall provide a lighting and photometric plan demonstrating that there shall not be any light spillage to nearby residential properties.

The proposed Zone Amendments and Reclassification identified up to 1,332 residential units on 69 candidate housing sites throughout the city (refer to Figure 2) and an additional 400 ADUs.

Development under the proposed Project would occur in already-developed urban areas, similar to the approved Housing Element Update. The R-40 Zoning Overlay would allow sites to be utilized for higher density low-income projects and increase the density of the sites that utilize the overlay to 40 units per acre. The densities of the candidate housing sites currently range from 25 to 35 units per acre. Implementation of the R-40 Zoning Overlay would increase the density on candidate housing sites by 5 to 15 units per acre, which would likely increase the heights of proposed housing developments. Nonetheless, future housing development under the proposed Project would be subject to the City’s development review process and be required to demonstrate consistency with General Plan policies and Municipal Code standards. Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the City of Pico Rivera
Zone Code Amendments and Zone Reclassification
10 additional residential units under the proposed Project would not result in a new significant impact affecting the existing aesthetic quality of the urban area as they would be compatible with the primary residences of single-family residential areas and they would comply with City development standards.

Effects and Mitigation Measures
No new significant impacts or substantial increase in previously identified significant impacts would occur related to aesthetics, and no new mitigation measures are necessary.

Conclusion
Less than Significant with Mitigation (Same as Approved Housing Element Update)

4.2 Agriculture and Forestry Resources
The 2022 approved Housing Element Update area consists of developed urban areas that do not contain Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmlands); agricultural uses; or forest land. Additionally, the approved Housing Element Update area is not under a Williamson Act contract or zoned for agriculture or forestry. No impact on agriculture and forestry resources would occur from implementation of the approved Housing Element Update.

The proposed Zone Amendments and Reclassification do not include any additional candidate housing sites that were not previously evaluated. Similar to the approved Housing Element Update, the proposed Project would not include agriculture or forestry uses and would not introduce nonagriculture or non-forest uses to areas designated/zoned for agriculture or forest land, nor would there be any sites under a Williamson Act contract or zoned for agriculture or forestry in the Plan area. The proposed Project does not change the number or location of any candidate housing sites in the city. Under the proposed Zone Amendments and Reclassification, owners and developers may utilize the R-40 Zoning Overlay in order to increase housing density to 40 units per acre and encourage the development of low-income housing. Similar to the approved Housing Element Update, the proposed Zone Amendments and Reclassification would not result in changes to land use or zoning that could lead to the conversion of agricultural or forested land in the City.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting the existing agricultural or forestry resources provided that they would be built within existing single-family residential areas. As a result, the proposed Project would not introduce new impacts or substantially increased impacts related to agriculture and forestry resources and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
No Impact (Same as Approved Housing Element Update)

4.3 Air Quality
The 2022 IS-MND determined that the approved Housing Element Update would be consistent with the standards and policies set forth in the 2016 Air Quality Management Plan (AQMP) and would not conflict with or obstruct implementation of the AQMP. The 2022 IS-MND also determined future housing development on candidate housing sites, at a minimum, would be required to meet CALGreen and Energy Code (CCR Title 24, Part 6) mandatory energy requirements in effect at the time of the development application. Projects would benefit from the efficiencies associated with these regulations as they relate to building heating, ventilating, and air conditioning mechanical systems, water heating systems, and lighting. Future housing development facilitated by the approved Housing Element Update would not result in a cumulatively considerable net increase of any criteria pollutant for which the South Coast Air Basin (SCAB) is in nonattainment under an applicable federal or State ambient air quality standard. In regard to sensitive receptor exposure to substantial pollutant concentrations, the approved Housing Element Update would not result in direct housing construction but would facilitate future housing development throughout the city consistent with State Housing laws.

Future housing development facilitated by the approved Housing Element Update would be subject to the City’s development review process to demonstrate that both daily construction emissions and operations would not exceed South Coast Air Quality Management District’s (SCAQMD) significance thresholds for any criteria air pollutant. Future housing development could result in odors generated from vehicles and/or equipment exhaust emissions during construction. Such odors would be temporary and generally would occur at magnitudes that would not affect substantial numbers of people. Therefore, all impacts related to air quality would be less than significant.

While the approved Housing Element Update was not found to have significant and unavoidable air quality impacts, future housing development would be required to follow all standard conditions as well as the following mitigation measures:

Measure SC AQ-1: The following measures shall be incorporated to minimize pollutant emissions associated with construction activities:
 Construction activities shall require the use of 2010 and newer diesel haul trucks (e.g., material delivery trucks and soil import/export) to the extent feasible. Under conditions where it is determined that 2010 model year or newer diesel trucks are not readily available or obtainable for a project, the applicant shall be required to provide this evidence to the City and shall instead use trucks that meet USEPA 2007 model year emissions requirements.
 All off-road diesel-powered construction equipment greater than 50 horsepower shall meet Tier 4 emission standards, where available. In addition, all stationary construction equipment shall be outfitted with the BACT devices certified by CARB. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine as defined by CARB regulations. A copy of each equipment unit’s certified tier specification, BACT documentation, and City of Pico Rivera
Zone Code Amendments and Zone Reclassification
12 CARB or South Coast AQMD operating permit shall be provided to the City at the time of mobilization of each applicable unit of equipment.

Measure SC AQ-2: The applicant shall require by contract specifications that constructionrelated equipment, including heavy-duty equipment, motor vehicles, and portable equipment, shall be turned off when not in use for more than five minutes. Contract specification language shall be reviewed by the City prior to issuance of a grading permit.

Measure SC AQ-3: The applicant shall require by contract specifications that construction operations rely on the electricity infrastructure surrounding the construction site rather than electrical generators powered by internal combustion engines to the extent feasible. Contract specification language shall be reviewed by the City prior to issuance of a grading permit.

Measure SC AQ-4: The applicant shall require by contract specifications that all off-road construction equipment engines shall be maintained in good condition and in proper tune per manufacturer’s specifications, to the satisfaction of the City Engineer. Equipment maintenance records and equipment design specifications data sheets shall be kept onsite during construction for periodic review by the City Inspector. Contract specification language shall be reviewed by the City prior to issuance of a grading permit.

Measure SC AQ-5: A project-specific localized emissions analysis shall be prepared that identifies the project’s construction emissions using either South Coast AQMD’s LST screening tables (for projects that are less than five acres) or dispersion modeling (for projects that exceed five acres in size). Where it is determined that construction emissions would exceed the applicable LSTs or the most stringent applicable federal or state ambient air quality standards, the project shall reduce its daily construction intensity (e.g., reducing the amount of equipment used daily, reducing the amount of soil graded/excavated daily, etc.) and/or use off-road construction equipment outfitted with the most stringent emissions control technology (e.g., equipment meeting Tier 4 emissions standards) such that the project’s resulting construction emissions would no longer exceed South Coast AQMD’s LSTs or result in pollutant emissions that would cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards.

Measure SC AQ-6: New sensitive land uses shall not be located within 1,000 feet of an existing or proposed distribution center/warehouse facility that generates more than 100 trucks per day, more than 40 trucks with operating TRUs per day, or where TRU unit operations exceed 300 hours per week. Under conditions where the 1,000-feet siting distance cannot be met, a health risk assessment (HRA) shall be conducted to evaluate the health risks to the new sensitive land uses from the TAC emissions generated from the mobile sources associated with the distribution center/warehouse facility. Based on the findings in the HRA, appropriate measures shall be taken, if necessary, to reduce the cancer risk resulting from TAC-exposure from mobile sources to below 10 in one million for the maximally-exposed individual. These measures may include, but are not limited to, implementation of appropriate Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 13 Minimum Efficiency Reporting Value (MERV) filters at the new sensitive land use development.

Measure SC AQ-7: For all residential projects proposed adjacent to the BNSF and Union Pacific railroads, an air quality study shall be prepared to determine the most effective buffering technique to ensure the exterior living areas are not exposed to substantial pollutant concentrations from the railroad.

Appropriate buffering shall be incorporated into the tentative subdivision map or other form of site plan submitted for approval by the City of Pico Rivera.

Measure SC AQ-8: All housing sites shall include air filtration systems designed to have a Minimum Efficiency Reporting Value (MERV) of 13 as indicated by the American Society of Heating Refrigerating and Air Conditioning Engineers (ASHRAE) Standard 52.2. The air handling systems shall be maintained on a regular basis per manufacturers recommendations by a qualified technician employed or contracted by the project proponent. Operation and maintenance of the system shall ensure that it performs at or above the minimum reporting value.

Measure SC AQ-9: Any development within the Emergency Shelter zone shall be designed and sealed inoperable windows combined with HVAC systems.

The approved Housing Element Update identifies policies and programs that could be implemented to provide additional capacity for future development of housing units consistent with State Housing Law. The approved Housing Element Update was found to be consistent with the standards and policies set forth in the 2016 AQMP and did not conflict with or obstruct implementation of the AQMP. The proposed Zone Amendments and Reclassification would increase the population to 67,764 residents by 2045 (see Section 14, Population and Housing). The current 2022 AQMP is based on the population projections in the 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) (Southern California Association of Governments [SCAG] 2020).

Population for Pico Rivera in the 2020-2045 RTP/SCS was estimated at 67,400 by 2045 (SCAG 2020).

This would constitute a 0.5 percent increase over SCAG’s 2045 population projection. In connection with the goals, policies, and programs of the approved Housing Element Update, the proposed Zone Amendments and Reclassification would provide the opportunity for higher-density development with affordable housing units. Individual projects under the proposed Project would be required to comply with applicable federal, State, regional, and local housing laws and policies. Therefore, it is not anticipated that future housing development facilitated by the proposed Zone Amendments and Reclassification would interfere with South Coast AQMD goals for improving air quality in the SCAB or conflict with or obstruct implementation of applicable air quality plans. As such, with respect to conflicting with or obstructing implementation of the applicable air quality plan, the proposed Project would be less than significant which is consistent with the approved Housing Element Update.

Regional and localized construction emissions under the proposed Zone Amendments and Reclassification would be similar in nature to those identified in the approved Housing Element City of Pico Rivera
Zone Code Amendments and Zone Reclassification
14 Update. Construction under the proposed Project would span eight years starting in 2023. As shown in Table 3, the daily construction emissions for each year of construction would be below the SCAQMD thresholds. Implementation of Measures SC AQ-1 through SC AQ-4 from the approved Housing Element Update would also apply to the future housing development under the proposed Project and would further reduce construction emissions. Therefore, due to the level of construction activities, construction emissions are anticipated to remain less than significant, which is consistent with the approved Housing Element Update.

Operational emissions from the proposed Zone Amendments and Reclassification would vary from the approved Housing Element Update due to the change in the type of land use anticipated in the proposed Project and associated zoning code amendments. Therefore, the proposed Project’s operational emissions were modeled in California Emissions Estimator Model (CalEEMod) (included as Appendix A) consistent with the methodology of the SCAQMD.1 As shown in Table 4, the net emissions would be below the SCAQMD’s regulatory thresholds for criteria pollutants. 1 Specific single-family residential sites are not identified for buildout of the additional 400 ADUs; however, they would be in single-family residential areas throughout the city. Based on zoning and development standards in Sections 18.40.040 and 18.42.040 of the Municipal Code, ADUs have a floor area not exceeding 1,200 square feet in a single-family residential zone. Therefore, for the purposes of the CalEEMod referenced in technical portions of this Addendum, this analysis assumes that the 400 ADUs would have a total floor area of 480,000 square feet and would be built on 12 acres (480,000 square feet = 12 acres). Furthermore, the 1,332 housing units from the R-40 Overlay Zone would be built upon 91.7 acres consistent with the acreage of the 69 candidate sites. The floor area associated with the 1,332 units was based on the CalEEMod default value, which assumed a floor area of 1,278,720 square feet (Appendix A).

Construction and operational impacts with respect to toxic air contaminants (TAC) would not substantially increase compared to those identified in the approved Housing Element Update since the nature of the development would not change under the proposed Zone Amendment and Reclassification. Construction impacts were determined to be less than significant under the approved Housing Element Update and, while activities are anticipated to increase under the proposed Project, construction impacts to health risk are anticipated to remain less than significant.

Due to the nature of the proposed land uses, the proposed Project is not anticipated to result in non-permitted emission sources and, consistent with the approved Housing Element Update, would not represent a risk to existing sensitive receptors from operational activities. Additionally, Measures SC AQ-1 through SC AQ-9 from the approved Housing Element Update would be implemented under the proposed Zone Amendment and Reclassification and would reduce potential exposure of new sensitive receptors to existing TAC sources. Therefore, these mitigation measures would also reduce potential impacts to new sensitive receptors under the proposed Project to less than significant levels.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting the existing air quality. With respect to construction impacts, construction under the proposed Zone Amendment and Reclassification would be consistent with those impacts identified in the approved Housing Element Update; therefore, as with the approved Housing Element Update, the proposed Project is not anticipated to exceed regulatory thresholds for criteria pollutants and therefore would be less than significant.

With respect to operational impacts, the proposed Zone Amendment and Reclassification would be consistent with the AQMP and would not exceed the regulatory thresholds. Therefore, consistent with the approved Housing Element Update, the proposed Zone Amendment and Reclassification would be less than significant.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update) City of Pico Rivera
Zone Code Amendments and Zone Reclassification
16 4.4 Biological Resources
Given that the approved Housing Element Update area is a highly disturbed, urban environment, the 2022 IS-MND determined that biological impacts would be less than significant. However, mitigation measures for future housing development will be required due to the City’s proximity to three major open space areas, and the potential impacts on candidate, sensitive, or special status wildlife or plant species through direct or indirect disturbance or elimination of essential habitat. All future housing developments facilitated by the Housing Element Update would also be required to incorporate measures for protecting biological resources from construction-related activities such as vegetation removal and degradation to plant and wildlife habitat.

The approved Housing Element Update would not result in direct housing construction but would facilitate future housing development throughout the City. There are no candidate housing sites proposed within the Whittier Narrows Recreation Area. The nearest candidate housing site is #64, which is about 1.7 miles south of the Whittier Narrows Recreation Area. All future housing development facilitated by the Housing Element Update would be required to demonstrate compliance with federal, State, and local requirements aimed at protecting biological resources.

Additionally, all future housing development facilitated by the Housing Element Update would be required to comply with measures for avoiding and minimizing construction and operations impacts to riparian habitat or other sensitive vegetation communities. The 2022 IS-MND determined that future housing development where the City has determined a potential for impacts to a wildlife corridor, would be required to prepare a site-specific general biological resources survey on sites that contain the presence of any sensitive biological resources. If vegetation clearing would occur during the bird breeding season (February 1 to July 15 for raptors and January 15 to August 31 for other birds), direct impacts to nesting birds could occur. Following compliance with the established regulatory framework, as well identified measures, future housing development would mitigate potential impacts to a less than significant level.

The City regulates roadside and parkway trees to protect biological resources. According to General Plan Environmental Resources Policy 8.6-4, Tree Preservation, the City shall preserve significant native and heritage trees and reduce the loss of these trees through mitigation and replanting programs, when feasible. All future housing development would be subject to the City’s development review process and requirements to demonstrate compliance with General Plan policies and Municipal Code regulations related to the removal or installation of public trees. The City of Pico Rivera is not located within the boundaries of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan.

The 2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing projects:

Measure SC BIO-1: Applications for future housing development facilitated by the Housing Element Update, where the City has determined a potential for impacts to special-status wildlife and plants species, shall be required to comply with the following mitigation framework:

Prior to the issuance of any permit for future development consistent with the Housing Element Update, a site-specific general biological resources survey shall be conducted on sites that contain the presence of any sensitive biological resources, including any sensitive plant or wildlife species. A Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 17 biological resources report shall be submitted to the City to document the results of the biological resources survey. The report shall include (1) the methods used to determine the presence of sensitive biological resources; (2) vegetation mapping of all vegetation communities and/or land cover types; (3) the locations of any sensitive plant or wildlife species; (4) an evaluation of the potential for occurrence of any listed, rare, and narrow endemic species; and (5) an evaluation of the significance of any potential direct or indirect impacts from the proposed project. If
potentially significant impacts to sensitive biological resources are identified, future project-level grading and site plans shall incorporate project design features required by the applicant to minimize direct impacts on sensitive biological resources to the extent feasible, and the report shall also recommend appropriate mitigation to be implemented by the applicant to reduce the impacts to below a level of significance.

Measure SC BIO-2: Applications for future housing development facilitated by the Housing Element Update, where the City has determined a potential for impacts to protected wetlands or other waters of the U.S. and State, shall be required to comply with the following mitigation framework: Prior to issuance of a permit for grading or vegetation removal, future housing development of candidate housing sites wherein the City has determined the potential for impacts to sensitive biological resources, shall be required to prepare a site specific biological resources survey. The limits of any riparian habitats on-site under the sole jurisdiction of CDFW shall be delineated, as well as any special aquatic sites (excluding vernal pools) that may not meet Federal jurisdictional criteria but are regulated by Coastal Commission and the RWQCB.

Measure SC BIO-3: Housing development activities facilitated by the Housing Element Update shall avoid the bird breeding season (typically January through July for raptors and February through August for other avian species), if feasible. If breeding season avoidance is not feasible, the applicant shall be responsible for a qualified biologist to conduct a pre-construction nesting bird survey prior to the commencement of any ground disturbing activities to determine the presence/absence, location, and status of any active nests on or adjacent to the survey area. The extent of the survey buffer area surrounding each site shall be established by the qualified biologist to ensure that direct and indirect effects to nesting birds are avoided. To avoid the destruction of active nests and to protect the reproductive success of birds protected by the Migratory Bird Treaty Act and the California Fish and Game Code and minimize the potential for project delay, nesting bird surveys shall be performed by the qualified biologist prior to project commencement.

In the event that active nests are discovered, a suitable buffer (distance to be determined by the biologist or overriding agencies) shall be established around such active nests, and no construction within the buffer shall allowed until the biologist has determined that the nest(s) is no long ger active (i.e., the nestlings have fledged and are no longer reliant on the nest).

While the 2022 IS-MND also acknowledges that an additional 400 ADUs would be developed atop the 1,332 housing units, it does not analyze a full buildout of 1,732 housing units. Therefore, this City of Pico Rivera
Zone Code Amendments and Zone Reclassification
18 analysis considers impacts associated with the development of an additional 400 ADUs for a total of 1,732 housing units under the Proposed project. Given that the Project area would remain the same for the proposed Zone Amendment and Reclassification, the proposed Project may have an impact on candidate, sensitive, or special status wildlife or plant species through direct or indirect disturbance or elimination of essential habitat. All future housing developments facilitated by the proposed Zone Amendment and Reclassification would also be required to incorporate measures from the approved Housing Element Update for protecting biological resources from constructionrelated activities such as vegetation removal and degradation to plant and wildlife habitat.

Similar to the approved Housing Element Update, there are no candidate housing sites proposed within the Whittier Narrows Recreation Area. The nearest candidate housing site is #64, which is about 1.7 miles south of the Whittier Narrows Recreation Area. Where the City has determined a potential for impacts to a wildlife corridor, would be required to prepare a site-specific general biological resources survey on sites that contain the presence of any sensitive biological resources. future housing development where the City has determined a potential for impacts to a wildlife corridor, would be required to prepare a site-specific general biological resources survey on sites that contain the presence of any sensitive biological resources. If vegetation clearing would occur during the bird breeding season (February 1 to July 15 for raptors and January 15 to August 31 for other birds), direct impacts to nesting birds could occur. Thus, the proposed Zone Amendment and Reclassification would incorporate the measures from the approved Housing Element Update to reduce impacts to sensitive biological resources to a less than significant level.

The proposed Zone Amendment and Reclassification would also be required to comply with the City’s General Plan Policy 8.6-4, Tree Preservation, in order to reduce the loss of trees though mitigation and replanting programs where feasible. Similar to the approved Housing Element Update, the proposed Project is not within the boundaries of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan. All future housing development facilitated by the proposed Project would be required to demonstrate compliance with federal, State, and local requirements aimed at protecting biological resources. Following compliance with the established regulatory framework, as well identified measures, future housing development would mitigate potential impacts to a less than significant level.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting biological resources. The proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to biological resources and would be consistent with the impact analysis provided in the 2022 IS-MND.

4.5 Cultural Resources
The 2022 IS-MND identified 13 buildings and sites with the potential for historical significance. One of the 13 sites, the La Mano building located at 9235 Whittier Boulevard, is on the California Register of Historical Resources. None of the other sites are currently listed on federal, State, or local registers. None of the candidate housing sites are located on the 13 identified, potentially historically significant sites. Nonetheless, future development on candidate housing sites could impact unidentified historical resources; therefore, projects would be required to comply with the established regulatory framework and apply Mitigation Measure SC CR-1 to preclude or mitigate impacts to historical resources.

The 2022 IS-MND determined that future housing development could disturb and potentially destroy subsurface prehistoric/historic archaeological resources or human remains through ground disturbances. All future housing development facilitated by the approved Housing Element Update on candidate housing sites would be subject to the City’s development review process and be required to adhere to all federal, State, and local requirements for avoiding impacts to archeological resources, including General Plan Policies 3.12-3 and 8.7-4, which require consultation with appropriate organizations and individuals to minimize potential impacts to historic and cultural resources and cultural resource surveys for all applicable projects. Mitigation Measures SC CR-2 and SC CR-3 may also be required by City staff. Future housing projects would be required to comply with the established regulatory framework and implement the mitigation program under the 2022 IS-MND to reduce impacts to a less than significant level.

The 2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing projects:

Measure SC CR-1: Applications for future development facilitated by the Housing Element Update, where the City has determined a potential for impacts to historic resources, shall be required to comply with the following mitigation framework: For any building/structures in excess of 50 years of age having its original structural integrity intact, the applicant shall retain a qualified professional historian to determine whether the affected building/structure is historically significant. The evaluation of historic architectural resources shall be based on criteria such as age, location, context, association with an important person or event, uniqueness, or structural integrity, as indicated in State CEQA Guidelines Section 15064.5. A historical resource report shall be submitted by the applicant to the City and shall include the methods used to determine the presence or absence of historical resources, identify potential impacts from the proposed project, evaluate the significance of any historical resources identified, and measures to avoid or mitigate significant impacts.

Measure SC CR-2: Applications for future development consistent with the Housing Element Update, where the City has determined a potential for impacts to archeological resources, shall be required to comply with the following mitigation framework: Prior to the issuance of any permit for future development located on a previously undisturbed site, the applicant shall retain a qualified archaeologist to conduct an archaeological survey to evaluate the presence of cultural resources and the need for project impact mitigation by preservation, relocation, or other methods. An archaeological resource report shall be submitted by the applicant to the City and shall City of Pico Rivera
Zone Code Amendments and Zone Reclassification
20 include the methods used to determine the presence or absence of archaeological resources, identify potential impacts from the proposed project, and evaluate the significance of any archaeological resources identified. If there are potentially significant impacts to an identified archaeological/cultural resource, the report shall also recommend appropriate mitigation required by the applicant to reduce impacts to below a level of significance.

Measure SC CR-3: If currently unknown resources are discovered during grading or demolition, such activity shall be halted or diverted away from the affected area of the project site, until a qualified archaeologist can examine the archaeological resources to determine their significance. If the find(s) are determined to be significant, the archaeologist shall provide recommendations regarding the collection, documentation, and disposition of the archaeological resources and shall provide recommendations on whether the remainder of the site that has not yet been disturbed should be monitored
The 2022 IS-MND analyzes the buildout of 1,332 units over 69 candidate housing sites but does not analyze the buildout of an additonal 400 ADUs. The proposed Zone Amendment and Reclassification does not change the number or location of any housing opportunity sites in the city. The proposed Project would accommodate up to 1,732 total future residential units which includes a 30 percent buffer and 400 ADUs. Under the proposed Zone Amendment and Reclassification , owners and developers may utilize the R-40 Zoning Overlay in order to increase housing density to 40 units per acre and encourage the development of low-income housing. Similar to the approved Housing Element Update area, the area for the proposed Project includes previously disturbed, urbanized developments. One of the 69 candidate housing sites is currently vacant, while the remaining 68 candidate housing sites contain existing development.

Similar to the approved Housing Element Update, none of the candidate housing sites under the proposed Project are located on the 13 identified, potentially historically significant sites. The likelihood of encountering archeological resources is greatest on undeveloped sites that have been minimally disturbed in the past (e.g., undeveloped parcels, vacant lots, and lots containing undeveloped areas), while previously disturbed sites are generally considered to have a lower potential for archeological resources since previous construction activities may have already removed or disturbed soil that may have contained resources. Notwithstanding, future housing development could disturb and potentially destroy subsurface prehistoric/historic archaeological resources through ground disturbances. For this reason, development projects under the proposed Zone Amendment and Reclassification would be required to comply with the established regulatory framework and implement Mitigation Measure SC CR-2.

There are no known burial sites or cemeteries in the City. Therefore, it is not anticipated that human remains would be present in the City outside formal cemeteries. However, human remains could be disturbed as a result of future development facilitated by the Housing Element Update. If human remains are found, those remains would require proper treatment in accordance with applicable laws, including State of California Health and Safety Code (HSC) Sections 7050.5 through 7055 and PRC Section 5097.98 and Section 5097.99. HSC Sections 7050.5 through 7055 describe the general provisions for treatment of human remains. In addition, development under the proposed Project would be required to comply with the established regulatory framework and implement Mitigation Measure SC CR-3, as needed, in order to reduce impacts to cultural resources.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 21 Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting cultural resources. Overall, the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to historic and archaeological resources and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.6 Energy
The 2022 IS-MND determined that it is expected that construction fuel consumption associated under the Housing Element Update would not be any more inefficient, wasteful, or unnecessary than other similar projects of this nature. Future development facilitated by the approved Housing Element Update would consume energy during operations through building electricity, water, and natural gas usage, as well as fuel usage from on-road vehicles. Future housing development must also comply with Mitigation Measure SC ENE-1, which requires the integration of energy conservation practices into new development projects, and all other applicable energy efficiency policies, such as CALGreen and the most current Building Energy Efficiency Standards. Therefore, implementation of the approved Housing Element Update would result in a less than significant impact on transportation‐related energy uses and would not result in a wasteful, inefficient, or unnecessary consumption of energy resources.

Future housing developments would be reviewed for consistency with City policies related to renewable energy and energy efficiency, and with all Federal and State energy regulations, such as the California Energy Code Building Energy Efficiency Standards (CCR Title 24, Part 6), the CALGreen Code (CCR Title 24, Part 11), and Senate Bill (SB) 743 transportation-related impact analysis requirements. Future housing development would also be required to comply with Mitigation Measure SC ENE-2, which requires the applicant to comply with all requirements of Southern California Edison and to obtain all required permits. Therefore, compliance with the existing regulatory setting and City requirements would reduce impacts to a less than significant level.

The2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing projects:

Measure SC ENE-1: Applicant to incorporate energy conservation practices into the project.

These may include:
i. Use of energy efficient or gas air conditioning systems and appliances. ii. Low wattage or LED lighting, long-life bulbs, sensors to automatically turn off/on outdoor lighting, lights with dimmers, etc. iii. Adequate insulation.
iv. Clean-burning or energy-efficient water heaters.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
22 v. Solar energy, if feasible.

Measure SC ENE-2: The applicant shall comply with all requirements of Southern California Edison and obtain all required permits.

Natural gas is provided to the City by Southern California Gas Company (SoCalGas). In 2020, a total of approximately 2,261 million therms of natural gas were consumed by SoCalGas’ residential customers (CEC 2021b). The proposed Project would result in approximately 229,275 therms of natural gas consumption per year. Development facilitated by the proposed Zone Amendment and Reclassification would utilize approximately 0.01 percent of SoCalGas supplies.

Similar to the approved Housing Element Update, all future housing development facilitated by the proposed Project would be subject to the City’s development review process and required to adhere to all federal, State, and local requirements for energy efficiency. This includes SB 32’s Scoping Plan that requires a 50 percent reduction in petroleum use in vehicles; SCAG’s 2020-2045 RTP/SCS, which calls for the support of land use and transportation planning strategies that reduce energy use and GHG emissions, the latest Title 24 standards, and applicable goals and policies under the City’s General Plan. In addition, the t design and materials for future developments would be subject to compliance with the most current Building Energy Efficiency Standards. Prior to issuance of a building permit, the City would review and verify that the individual project plans demonstrate compliance with the current version of the Building and Energy Efficiency Standards. Individual projects would also be required adhere to the provisions of CALGreen, which establishes planning and design standards for sustainable site development, energy efficiency (in excess of the California Energy Code requirements), water conservation, material conservation, and internal air contaminants. Upon compliance with all applicable standards and requirements, along with implementation of Mitigation Measures SC ENE-1 and ENE-2, future housing development under the proposed Project would result in a less than significant impact on transportation‐related energy uses and would not result in a wasteful, inefficient, or unnecessary consumption of energy resources.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting energy. Potential energy impacts would be less than significant and would be consistent with the 2022 IS-MND and approved Housing Element Update.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 23 Effects and Mitigation Measures
No new significant impacts or substantial increase in previously identified significant impacts would occur related to aesthetics, and no new mitigation measures are necessary.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.7 Geology and Soils
The 2022 IS-MND determined that implementation of the Housing Element Update would not result in impacts relating to rupture of a known earthquake fault, liquefaction, landslides, and soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems, and would result in less-than-significant impacts relating to seismic ground shaking, unstable soils, and expansive soils (Section 4.7, Geology and Soils, of the 2022 IS-MND). There are no known earthquake faults that traverse the City. In addition, all development facilitated under the Housing Element Update would be subject to the City’s development review process and adherence to all federal, State, and local requirements for avoiding and minimizing seismic-related impacts.

The 2022 IS-MND determined that while the potential for differential settlement, landslides, and seiches exist within the City, given soil, topographic and other conditions, their likelihood, and potential severity are generally limited. All future housing development facilitated by the Housing Element Update would be subject to the City’s development review process and be required to adhere to all local, State, and federal requirements for avoiding and minimizing seismic-related impacts. In addition, future housing development facilitated by the Housing Element Update would not create substantial risks to life or property associated with unstable and expansive soils.

Regarding septic tanks, housing developed through the approved Housing Element Update would be in areas currently served by the City’s sanitary sewer system and would not use septic tanks or other alternative wastewater disposal systems. Regarding paleontological resources, General Plan Environmental Resources Element Policy 8.7-4 requires that new development necessitating discretionary approval that could potentially impact paleontological resources to conduct a resource survey to ensure that potential sites are identified for avoidance or special treatment. Therefore, the overall impacts associated with geology and soils under the approved Housing Element Update were determined to be less than significant and mitigation would not be required.

There are no known earthquake faults that traverse the City. In addition, all development facilitated under the proposed Project would be subject to the City’s development review process and adherence to all federal, State, and local requirements for avoiding and minimizing seismic-related impacts. Similar to the approved Housing Element Update, adherence with statewide National Pollutant Discharge Elimination System (NPDES) Construction General Permit construction requirements would ensure erosion would not occur onsite through implementation of erosion and sediment control best management practices (BMP) during construction of individual projects under the proposed Project. Therefore, impacts regarding seismicity and soil erosion would be less than significant. Similarly, given the same number and location of candidate housing sites as the approved Housing Element Update, potential impacts associated with septic tanks and paleontological resources under the proposed Project would be less than significant.

All future housing development facilitated by the proposed Zone Amendment and Reclassification would be subject to the City’s development review process, and adherence to all federal, State, and City of Pico Rivera
Zone Code Amendments and Zone Reclassification
24 local requirements for avoiding and minimizing impacts concerning soil erosion or loss of topsoil, including the City’s Grading and Excavation Code (Municipal Code Section 15.08.220), which establishes minimum requirements for grading, excavating and filling of land, and provides for the issuance of permits. Construction-related erosion would be addressed through compliance with the NPDES program, which requires implementation of a Storm Water Pollution Prevention Plan (SWPPP) and BMPs intended to reduce soil erosion. Impacts would remain less than significant.

All future housing development facilitated by the proposed Zone Amendment and Reclassification would be subject to the City’s development review process, and adherence to all federal, State, and local requirements, including the City’s Building Code (Municipal Code Chapter 15.08), and the City’s Grading and Excavation Code (Municipal Code Section 15.08.220), which require sets of plans and specifications, a Soils Engineering Report, and an Engineering Geology Report before issuance of grading permits (Municipal Code Section 15.08.220). Therefore, future housing development would not create substantial adverse risks to life or property associated with liquefaction and impacts would be less than significant.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting geology and soils. As a result, development of the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to geology, soils, and seismicity, and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.8 Greenhouse Gas Emissions
The 2022 IS-MND determined that future housing development facilitated by the approved Housing Element Update would have a less than significant impact on GHG emissions. The approved Housing Element Update does not include the rezoning of any parcels. Thus, future growth and development facilitated by the approved Housing Element Update would have been accounted for in the General Plan EIR and SCAG RTP. The approved Housing Element Update, and future development facilitated by the Housing Element Update, would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. Impacts would be less than significant.

SCAG’s RTP/SCS includes a commitment to reduce emissions from transportation sources by promoting compact and infill development to comply with SB 375. Consistent with the approved Housing Element Update, the proposed Zone Amendment and Reclassification would implement many of the SCAG policies related to high-density, infill development that are focused on public Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 25 transit opportunities, and would involve the revitalization of an already developed urban area with infill development that would make use of the existing circulation and utility infrastructure. The proposed Project would also introduce high density residential uses, thus creating a mixed-use environment in which residents would benefit from nearby shopping and employment opportunities. Future development would be within walking distance of the varying modes of public transportation, which would encourage the use of public transportation and reduce GHG emissions.

Similar to the approved Housing Element Update, the proposed Zone Amendment and Reclassification is consistent with the General Plan. The proposed Project would amend some General Plan land uses and zoning designations of parcels to implement the approved Housing Element Update. As a result, the City would coordinate with SCAG to adjust the City’s households forecast in future updates to the RTP/SCS. Overall, the proposed Project would not result in a conflict with the General Plan because it is generally consistent with the goals and policies of the General Plan that aim at enhancing Pico Rivera by introducing mixed uses and creating a pedestrianfriendly environment.

There are numerous State plans, policies, and regulations adopted for the purpose of reducing GHG emissions. The principal State plan and policy is AB 32, the California Global Warming Solutions Act of 2006, as well as SB 32. The quantitative goal of AB 32 is to reduce GHG emissions to 1990 levels by 2020 and the goal of SB 32 is to reduce GHG emissions to 40 percent below 1990 levels by 2030.

The 2022 Scoping Plan Update identifies plans and regulations and strategies that are to be implemented at the State and project level that will reduce GHG emissions consistent with State policies. The proposed Zone Amendments and Reclassification would be required to include all mandatory green building measures for new developments under the CALGreen Code. Therefore, the proposed Project would be consistent with the Scoping Plan measures through incorporation of these stricter building and appliance standards. The proposed Project’s GHG emission were also quantitatively analyzed and are provided in this analysis for informational purposes.

Amortized over a 30-year period pursuant to SCAQMD guidance, construction associated with the project would generate approximately 648 MT CO2e per year. As shown in Table 5, annual average operational GHG emissions for the proposed Project would be approximately 4,477 MTCO2e.

Table 5 Annual Emissions

See Appendix A for CalEEMod results.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project City of Pico Rivera
Zone Code Amendments and Zone Reclassification
26 would not result in a new significant impact affecting GHGs. As a result, implementation of the proposed Zone Amendment and Reclassification would not generate GHG emissions that would be significant, and impacts would be consistent with the approved Housing Element Update.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.9 Hazards and Hazardous Materials
The 2022 IS-MND determined that hazards and hazardous materials impacts from implementation of the approved Housing Element Update would be less than significant with mitigation incorporated. It was determined that impacts associated with the transport, use, or disposal of hazardous materials would be less than significant following compliance with the established regulatory framework. Potential impacts involving the accidental discovery of unknown wastes or suspect materials during construction would also be less than significant following compliance with the established regulatory framework. If a project is located within 0.25 miles of an existing or proposed school, adherence to California Hazardous Waste Control Law, California Health and Safety Code, and Resource Conservation and Recovery Act (RCRA) regulations would reduce potential impacts associated with the accidental release of hazardous materials.

Given the scope and location of the future housing development facilitated by the Housing Element Update, potential impacts associated with impairment or conflicts with implementation of emergency response plans would be less than significant. In addition, it was determined that there would be no impact to airports as there are no airports in Pico Rivera, and there would be no impacts in regard to exposure to wildfire resulting in a significant risk of loss, injury or death as the approved Housing Element Update area is fully urbanized, not adjacent to any wildland, and is located in a Non-Very High Fire Hazard Severity Zone.

However, the 2022 IS-MND discloses that the DTSC Envirostor database and State Water Resources Control Board Geo Tracker database identified 13 regulated facilities and 76 regulated facilities in the City, respectively. Future housing development facilitated by the approved Housing Element Update could occur near identified regulated facilities. Therefore, Mitigation Measure SC HAZ-1 was identified to ensure that any potential discovery of unknown wastes or suspect materials during construction that are believed to involve hazardous waste or materials are properly handled to reduce any hazards to the public or the environment. Upon implementation of this measure, potential impacts were found to be mitigated to a less than significant level.

The2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing project:

Measure SC HAZ-1: If the Applicant or Applicant’s contractor discovers unknown wastes or suspect materials during construction that are believed to involve hazardous waste or materials, the applicant or applicant’s contractor shall:

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 27

1. Immediately cease work in the suspected contaminant’s vicinity, remove workers and the public from the area, and secure the area.

2. Notify the applicant’s Environmental Professional and immediately implement proper remedial activities as recommended.

3. Notify the City Engineer and Planning Division Director and implement measures to further secure the area.

4. The Hazardous Waste/Materials Coordinator shall advise the responsible party of further actions that shall be taken, if required.

While the 2022 IS-MND also acknowledges that an additional 400 ADUs would be developed atop the 1,332 housing units, it does not analyze a full buildout of 1,732 housing units. Therefore, this analysis considers impacts associated with the development of an additional 400 ADUs for a total of 1,732 housing units under the Proposed project. Small quantities of hazardous materials would be anticipated, including cleaning solvents, fertilizers, pesticides, and other materials used in regular maintenance. On the local level, the Los Angeles County Fire Department routinely provides inspections to ensure the safe storage, management, and disposal of any hazardous materials in accordance with the federal, State, and local regulations. Potential impacts involving the accidental discovery of unknown wastes or suspect materials during construction would be less than significant upon compliance with the established regulatory framework. If a project is located within 0.25 miles of an existing or proposed school, adherence to California Hazardous Waste Control Law, California Health and Safety Code, and Resource Conservation and Recovery Act (RCRA) regulations would reduce potential impacts associated with the accidental release of hazardous materials.

Similar to the approved Housing Element Update, it is not anticipated that implementation of the proposed Zone Amendment and Reclassification would impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Future housing development facilitated by the proposed Project would be subject to the City’s development review process and compliance with 2019 California Fire Code Chapter 503, Fire Apparatus Access Roads, which specifies how fire access roads are required to be designed for new developments. Impacts to emergency response plans or emergency evacuation plans would be less than significant. In addition, similar to the approved Housing Element Update, the proposed Project is located in a NonVery High Fire Hazard Severity Zone and would not expose people or structures to significant risk, injury, or death involving wildland fires.

Since all candidate housing sites are the same for the proposed Zone Amendment and Reclassification, future housing development facilitated by the proposed Project could occur near identified regulated facilities. Therefore, the proposed Zone Amendment and Reclassification would be required to incorporate Measure SC HAZ-1 from the 2022 IS-MND in order to reduce any hazards to the public or the environment.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact associated with hazards and hazardous materials. Thus, the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to hazards and hazardous materials and would be consistent with the impact analysis provided in the 2022 IS-MND.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
28 Effects and Mitigation Measures
No new significant impacts or substantial increase in previously identified significant impacts would occur related to aesthetics, and no new mitigation measures are necessary.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.10 Hydrology and Water Quality
The 2022 IS-MND determined that hydrology and water quality impacts from implementation of the approved Housing Element Update would be less than significant. Construction and operation of future development under the implementation of the approved Housing Element Update could result in discharges of hazardous materials, sediment, and stormwater that could contaminate downstream waters. Compliance with required laws, permits, ordinances, and plans, including but not limited to Low Impact Development (LID) and Construction General Permit requirements would reduce impacts to hydrology and water quality to a less-than-significant level. However, all housing opportunity sites are developed except for one, which would increase impervious surfaces and offsite runoff that would have the potential to degrade surface or groundwater quality. To minimize this impact, future housing development facilitated by the Housing Element Update would be subject to the City’s development review process, and requirements to install, implement, and maintain the BMPs identified in Municipal Code Section 16.04.110 and SC HYD-1 including, but not limited to materials storage; inspection, maintenance, and upgrade of BMPs, and the preparation of Standard Urban Stormwater Mitigation Programs (SUSMP). All new development would also be required to comply with existing water quality standards and waste discharge regulations set forth by the State Water Resources Control Board (SWRCB). Future developments facilitated by the Housing Element Update would comply with these regulations and waste discharges would be connected to the public wastewater system.

The 2022 IS-MND found that the following measure shall be implemented as a standard condition/condition of approval for future housing projects:

Measure SC HYD-1: The applicant shall implement various Best Management Practices (BMPs) during the construction process in order to control and filter potential stormwater runoff that may accumulate during the project’s construction.

These construction BMPs shall include the following:
 Runoff, sediment, and construction debris shall not leave the site and enter the storm drain system.
 Any sediment or other materials which are tracked off-site shall be removed the same day as they are tracked off-site. Where determined necessary by the authorized enforcement officer, a temporary sediment barrier shall be installed.
 Drainage controls to prevent runoff from leaving the site shall be utilized as needed, depending on the topography of the site and extent of proposed grading. These controls may include but are not limited to the following: the detention ponds, sediment ponds, or infiltration pits; the installation of dikes, filer berms, or ditches; and the installation of down drains, chutes or flumes.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 29  Plastic covering may be utilized to prevent erosion of an otherwise unprotected area, along with runoff devices to intercept and safely convey the runoff.
 Excavated soil shall be located on the site in a manner that eliminates the possibility of sediments running off-site. Soil piles shall be covered until the soil is either used or removed.
 No runoff from washing construction or other industrial vehicles on site shall be permitted to leave the site or enter the storm drain system.  The City may, as a condition of granting a construction permit, set reasonable limits on the clearing of vegetation from construction sites, including but not limited to regulating the length of time during which soil may be bare and, in certain sensitive cases, prohibit bare soil.

The 2022 IS-MND analyzes the buildout of 1,332 units over 69 candidate housing sites but does not analyze the buildout of an additonal 400 ADUs. The proposed Zone Amendment and Reclassification does not change the number or location of any candidate housing sites in the city. The proposed Project would accommodate up to 1,732 total future residential units which includes a 30 percent buffer and 400 ADUs. Under the proposed Project, owners and developers may utilize the R-40 Zoning Overlay in order to increase housing density to 40 units per acre and encourage the development of low-income housing.

Similar to the approved Housing Element Update, if future developments disturb more than one acre of land surface, they would be required to obtain coverage under the NPDES storm water program. The NPDES Construction General Permit program calls for the implementation of BMPs to reduce or prevent pollutant discharge from these activities to the Maximum Extent Practicable for urban runoff and to meet the Best Available Technology Economically Achievable and Best Conventional Pollutant Control Technology standards for construction storm water. Construction activities would be required to comply with a Project-specific SWPPP that identifies erosion-control and sediment-control BMPs that would meet or exceed measures required by the Construction Activity General Permit to control potential construction-related pollutants. Additionally, the proposed Zone Amendment and Reclassification would be subject to the City’s development review process, and requirements to install, implement, and maintain the BMPs identified in Municipal Code Chapter 16.04 and Measure SC HYD-1 from the 2022 IS-MND in order to reduce construction and operational impacts to run off.

Implementation of the proposed Zone Amendments and Reclassification would not substantially alter drainage patterns or expose additional residents to flood-related hazards. Future housing development facilitated by the proposed Project would be subject to the City’s development review process and adherence to all federal, State, and local requirements for avoiding construction and operations impacts that could substantially alter the existing drainage pattern or alter the course of a stream or river, including the City’s Municipal Code and Measure SC HYD-1 from the 2022 IS-MND.

Similarly, the proposed Project would be required to comply with the City’s Urban Water Management Plan, Municipal Code standards, and SC HYD-1. As a result, future housing development facilitated by the proposed Project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting hydrology and water quality. Overall, the City of Pico Rivera
Zone Code Amendments and Zone Reclassification
30 proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to hydrology and flooding and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.11 Land Use Planning
The 2022 IS-MND determined that the approved Housing Element Update does not include infrastructure improvements that would bisect existing established communities. Out of the 69 candidate housing sites, 68 are developed in urban areas and would be considered in-fill developments. Further, candidate housing sites have been identified throughout the City, rather than concentrated in a single area, and therefore, would not divide an established community.

Future housing development facilitated by the approved Housing Element Update would be subject to the City’s development review process, and requirements to comply with applicable federal, State, and local laws and local policies and regulations, as applicable to new housing development.

As such, the approved Housing Element Update would be consistent with applicable land use and planning policies in the State, regional, and local context as necessary to meet that legislation. Land use impacts were found to be less than significant under the approved Housing Element Update.

The proposed Zone Amendment and Reclassification would not result in direct housing construction but would facilitate future housing development as market conditions allow and at the discretion of the owners. In addition, the proposed Project would provide the option to owners and developers to utilize the R-40 Zoning Overlay to produce low-income housing in higher densities on the candidate housing sites. Future housing development facilitated by the proposed Project would be subject to the City’s development review process, and requirements to comply with applicable federal, State, and local laws and local policies and regulations, as applicable to new housing development. As such, the proposed Zone Amendment and Reclassification would be consistent with applicable land use and planning policies in the State, regional, and local context as necessary to meet that legislation.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting land use and planning. The proposed Project Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 31 would not introduce new impacts or substantially increased impacts related to land use and planning, and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.12 Mineral Resources
The area analyzed under the 2022 IS-MND consists of developed urban land. The Surface Mining and Reclamation Act of 1975 (SMARA) requires classification of land into mineral resource zones (MRZs) according to the area’s known or inferred mineral potential. The City is not located in an area identified as a locally important mineral resource recovery site. Further, the General Plan does not identify any part of the City as a locally important mineral resource recovery site. Therefore, the approved Housing Element Update would have no impact concerning mineral resources and no mitigation is required.

Although the proposed Project analyzes the additional 400 ADUs in comparison to the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting mineral resources. As a result, the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to mineral resources and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.13 Noise
The 2022 IS-MND determined that noise and vibration-related impacts from new development under the approved Housing Element Update could be divided into construction impacts and operational impacts (see Section 4.13, Noise, of the 2022 IS-MND). New development would comply City of Pico Rivera
Zone Code Amendments and Zone Reclassification
32 with the City’s existing noise standards and daytime construction hours permitted by the City’s Municipal Code. Standard Conditions/Conditions of Approval have been identified for constructionrelated activities, including but not limited to preparation of a Noise Mitigation Plan; identification of a noise disturbance coordinator and provide a hotline number to allow community members to voice any noise complaints resulting from construction activities; and BMPs that applicants must comply with during construction to reduce noise impacts from the construction of housing developments. Future housing development facilitated by the approved Housing Element Update would result in additional housing, people, pets, and automobiles in the City. Noise would be generated by stationary operation-related sources, such as heating, ventilation, and air conditioning (HVAC) units, generators, lawn maintenance equipment, and swimming pool pumps.

All future housing development would be subject to the City’s development review process, compliance with Municipal Code standards, and adherence to the mitigation measures identified under the 2022 IS-MND (listed below). Therefore, upon compliance with applicable regulations and implementation of the applicable measures, construction and operation noise impacts would be mitigated to a less than significant level.

Similarly, construction facilitated by the approved Housing Element Update could adversely impact buildings located near construction sites depending on soil type, ground strata, and construction characteristics of the receiver buildings. To further lessen the potential vibration-related impacts to historic resources and sensitive uses (i.e., nonengineered timber and masonry buildings), the 2022 IS-MND includes measures related to the location and use of equipment. Alternative installation methods could reduce vibration impacts below the 0.2 inch/second threshold. Residential uses would not be anticipated to generate excessive groundborne vibration. Therefore, impacts related to groundborne vibration from construction or operation of the approved Housing Element Update would be mitigated to a less than significant level.

There would be no impacts regarding airport noise, as the nearest airport to the approved Housing Element Update area is the Long Beach Airport located approximately 15 miles south. The City of Pico Rivera is not within the Airport’s influence area and thus, no impact would occur.

The 2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing projects:

Measure SC NOI-1: The City shall consider all future developments to ensure their compliance with Policies 11.1-1 through 11.2-6 in the Noise Element of the General Plan Update and determine if operational noise levels generated by the development would exceed the City’s permissible noise standards for transportation and stationary noise sources established in the Noise Element.

If City noise standards would be exceeded, design measures shall be taken to ensure that operational noise levels would be reduced to levels that comply with the permissible City noise standards to the extent feasible. These measures may include, but are not limited to, the erection of noise walls, use of landscaping, and/or the design of adequate setback distances for the new developments.

Measure SC NOI-2: Concurrent with submittal of a project application at any of the Housing Opportunity locations, the project proponent shall submit a noise study to evaluate existing and projected noise levels that could affect residences within the project sites to assure that exterior and interior noise levels meet City noise standards. If noise standards are exceeded, measures to attenuate noise levels shall be required to attenuate noise to levels that in accordance Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 33 with City standards. Noise studies shall be prepared to the satisfaction of the City’s Community Development Director.

Measure SC NOI-3: All dwelling units shall maintain interior noise levels that do not exceed 45 dBA, when all windows and doors are closed.

Measure SC NOI-4: All construction activities shall take place only between the hours of 7:00 a.m. and 7:00 p.m. in compliance with Policies 11.3-1 and 11.3-2 in the Noise Element of the General Plan.

Measure SC NOI-5: Applicant shall submit a Noise Mitigation Plan to the Community and Economic Development – Planning Division for review and approval. The Plan shall depict the location of construction equipment storage and maintenance areas, and document methods to be employed to minimize noise impacts on adjacent noise sensitive land uses.

Measure SC NOI-6: During the construction phase, the applicant shall designate a noise disturbance coordinator who will be responsible for responding to neighborhood complaints about construction noise by determining the cause of the noise complaints and require implementation of reasonable measures to correct the problem. The noise disturbance coordinator and their responsibilities shall be identified and reflected within the Noise Mitigation Plan. The coordinator’s telephone number(s) shall be prominently displayed at construction locations.

Measure SC NOI-7: The applicant shall be responsible for providing a hotline number that adjacent residents or businesses may call with concerns or questions regarding construction activities. The hotline number shall be made available 24 hours a day, 7 days a week and shall be answered with a live person.

Applicant shall install and maintain a temporary construction sign displaying the hotline number within the project site during the construction phase. A site plan and to-scale elevations of the temporary construction sign shall be submitted to the Community and Economic Development Department – Planning Division for review and approval, prior to installation. The hotline number and its operation details shall be identified and reflected within the Noise Mitigation Plan.

Measure SC NOI-8: All construction equipment shall utilize noise reduction features (e.g., mufflers and engine shrouds) that are no less effective than those originally installed by the manufacturer.

Measure SC NOI-9: Approval of development permits shall ensure that the operation of jackhammers shall be prohibited within 25 feet of existing residential structures and 20 feet of institutional structures during construction activities associated with any project-specific development, to the extent feasible.

Measure SC NOI-10: The City shall require a preconstruction meeting with the City’s job inspector(s) and the general contractor or onsite project manager to confirm that noise and vibration mitigation and practices (including construction hours, sound mufflers on equipment, neighborhood notification, posted signs, etc.) are implemented.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
34 Measure SC NOI-11: The City shall ensure that stationary construction noise sources be located as far from adjacent receptors as possible, and they shall be muffled and enclosed within temporary sheds, incorporate insulation barriers, or other measures to the extent feasible. Construction equipment staging and storage areas shall be located as far from nearby residential uses as possible. The City shall ensure that project approvals require that construction activities whose specific location on a construction site may be flexible (e.g., operation of compressors and generators, cement mixing, general truck idling) be conducted as far as possible from the nearest noise-sensitive land uses.

Measure SC NOI-12: During the construction phase, prohibit and post signs prohibiting unnecessary idling of internal combustion engines.

Measure SC NOI-13: During the construction phase, utilize “quiet” air compressors and other stationary equipment where feasible and available.

Measure SC NOI-14: All haul truck deliveries shall be subject to the same hours specified for construction. A haul truck route plan shall be provided to the Public Works Department for review and approval, prior to the commencement of any construction activities. The plan shall denote any construction traffic haul routes where heavy trucks would exceed 100 daily trips (counting those both to and from the construction site). To the extent feasible, the plan shall denote haul routes that do not pass sensitive land uses or residential dwellings.

Measure SC NOI-15: Approval of development permits shall ensure that where a new development would be constructed adjacent to an existing historic building, the project developer shall require by contract specifications that a certified structural engineer be retained to submit evidence that the operation of vibration-generating equipment associated with the new development would not result in any structural damage to the adjacent historic building. Contract specifications shall be included in the construction documents for the new development, which shall be reviewed by the City prior to issuance of a construction permit.

Measure SC NOI-16: The City shall require that all construction truck traffic be restricted to routes approved by the City of Pico Rivera, which shall avoid residential areas and other sensitive receptors to the extent feasible.

Measure SC NOI-17: To avoid impacts to vibration-sensitive structures (i.e., non-engineered timber and masonry buildings) located within a 50-foot radius of pile driving activities, prior to demolition, grading, or building permit approval, the applicant shall provide for the following measures to be specified on the project plans and implemented prior to and during construction:
 Construction equipment that generates high levels of vibration, such as large bulldozers, loaded trucks, and caisson drills, shall be prohibited within 45 feet of residential structures and 35 feet of institutional structures during construction of any project-specific development to the extent feasible. Small, rubber-tired construction equipment shall be used within this area during demolition and/or grading operations to reduce vibration effects, where feasible.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 35  The applicant shall utilize temporary noise attenuation curtain suitable for pile driving equipment as needed. This noise attenuation device should be installed directly between the equipment and the nearest noise sensitive receptor to the construction site.
 Pile driving within a 50-foot radius of identified vibration-sensitive structures shall utilize alternative installation methods (e.g., pile cushioning, jetting, predrilling, castin-place systems, resonance-free vibratory pile drivers) such that vibration velocities from the alternative construction activity would fall below the 0.2 the inch/second threshold.

Construction hours, allowable workdays, and the phone number of the job superintendent shall be clearly posted at all construction entrances to allow for surrounding owners and residents to contact the job superintendent. If the City or the job superintendent receives a complaint, the superintendent shall investigate, take appropriate corrective action, and report the action taken to the reporting party.

Measure SC NOI-18: Approval of development permits shall ensure that individual developments minimize noise impacts from mechanical equipment, such as ventilation and air conditioning units, by locating equipment away from receptor areas, installing proper acoustical shielding for the equipment, and incorporating the use of parapets into building design to ensure that noise levels shall not exceed the noise level standards for stationary noise sources in the Noise Element of the General Plan Update.

As shown in Table 4.13-1 of the 2022 IS-MND, typical construction equipment can range from 77 to 90 dBA to a person or structure located 50 feet from the noise source. Similar to the approved Housing Element Update, the proposed Zone Amendment and Reclassification would be required to incorporate the mitigation measures, listed above, in order to reduce impacts related to construction noise to a less than significant level. Future housing development facilitated by the proposed Project would result in additional housing, people, pets, and automobiles in the City.

Noise would be generated by stationary operation-related sources, such as heating, ventilation, and air conditioning (HVAC) units, generators, lawn maintenance equipment, and swimming pool pumps. The proposed Project would require adherence to the mitigation measures identified under the 2022 IS-MND to reduce operational noise impacts from the Project. In addition, the proposed Zone Amendment and Reclassification would be subject to the City’s development review process and compliance with the Municipal Code standards regarding construction and operational noise.

Construction activities associated with future housing development facilitated by the proposed Zone Amendment and Reclassification could result in varying degrees of groundborne vibration impacts from heavy equipment operations, depending on the construction procedure and equipment used.

Construction equipment operations would generate vibrations that spread through the ground and diminish in amplitude with distance from the source. The effect on buildings located near a construction site often varies depending on soil type, ground strata, and construction characteristics City of Pico Rivera
Zone Code Amendments and Zone Reclassification
36 of the receiver building(s). The FTA architectural damage criterion for continuous vibrations (i.e., 0.2 inch/second) appears to be conservative even for sustained pile driving. Pile driving levels often exceed 0.2 inch/second at distances of 50 feet, and 0.5 inch/second at 25 feet without any apparent damage to buildings. Types of construction vibration impacts include human annoyance and building damage. As shown in Table 4.13-2 of the 2022 IS-MND, groundborne vibration peak particle velocity from 25 feet away can range from 0.003 inches per second to 0.210 inches per second for typical standard equipment. Similar to the approved Housing Element Update, the proposed Project would include the mitigation measures presented in the 2022 IS-MND to further lessen the potential vibration-related impacts to historic resources and sensitive uses. Residential uses would not be anticipated to generate excessive groundborne vibration. Future housing development facilitated by the proposed Project would not involve railroads or substantial heavy truck operations, and therefore would not result in vibration impacts at surrounding uses.

New development under the proposed Zone Amendment and Reclassification would be exposed to intermittent noise levels from aircraft overflights, similar to buildout under the approved Housing Element Update. However, the proposed Project area is not located within an airport’s noise contours and development would not impact air traffic patterns. The nearest airport is Long Beach Airport located approximately 15 miles south of the proposed Project area. Therefore, similar to the approved Housing Element Update, no noise impacts related to exposure of aircraft operations would occur under the proposed Zone Amendment and Reclassification.

Compliance with existing State regulations, approved Housing Element Update mitigation measures, regulations, and policies relating to noise, and requirements included in the City’s Municipal Code would collectively reduce noise impacts associated with the proposed Project. Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting noise. As a result, development under the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to noise and vibration and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant with Mitigation (Same as Approved Housing Element Update)

4.14 Population and Housing
The 2022 IS-MND determined that the project would exceed SCAG’s population project of 67,400 by 2045. Future housing development facilitated by the approved Housing Element Update would result in population growth of approximately 4,942 persons. However, SCAG recognized that its growth projections do not constitute a prescriptive pattern for the General Plan or zoning code amendment. Potential exceedances may not be used to impede a jurisdiction’s compliance with the 6th Cycle RHNA requirements. In addition, future housing development facilitated by the Housing Element Update would be subject to the City’s development review process, and requirements to comply with applicable federal, State, and local laws and local policies and regulations, as applicable Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 37 to new housing development. As such, the approved Housing Element Update would be consistent with applicable land use and planning policies in the State, regional, and local context as necessary to meet that legislation. Impacts would be less than significant.

The 2022 IS-MND determined that compliance with SB 166 would minimize the potential for future housing displacement. All approved Housing Element Update actions would occur such that there is no net loss of residential unit capacity. Therefore, there would be no impact concerning displacements of substantial numbers of existing people or housing and the construction of replacement housing.

The proposed Zone Amendment and Reclassification does not change the number or location of any housing opportunity sites in the city. The proposed Project would accommodate up to 1,732 total future residential units which includes a 30 percent buffer and 400 ADUs. Under the proposed Project, owners and developers may utilize the R-40 Zoning Overlay in order to increase housing density to 40 units per acre and encourage the development of low-income housing. Similar to the approved Housing Element Update, the proposed Zone Amendment and Reclassification would exceed SCAG’s growth projection. The City has a total existing population of 61,338 people. A total of 1,732 units would increase the population of Pico Rivera by 6,426 residents. This would constitute a 0.5 percent increase over SCAG’s 2045 population projection of 67,400 residents. Similar to the approved Housing Element Update, the proposed Project would be required to be in compliance with all state housing law. Potential exceedances of the projected population may not be used to impede the City’s compliance with the 6th Cycle RHNA. Future housing development facilitated by the proposed Project would be subject to the City’s development review process, and requirements to comply with applicable federal, State, and local laws and local policies and regulations, as applicable to new housing development.

Similar to the approved Housing Element Update, compliance with SB 166 would minimize potential for future housing displacement. In addition, the R-40 Zoning Overlay aims to increase residential unit capacity. The proposed Project would have no impact concerning the displacement of substantial numbers of existing people or housing and the construction of replacement housing.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting population and housing. As a result, the proposed Zone Amendment and Reclassification would not introduce new or substantially increased impacts related to land use and would be consistent with the impact analysis provided in the approved Housing Element Update IS-MND.

Conclusion
Less Than Significant (Same as Approved Housing Element Update)

4.15 Public Services
The 2022 IS-MND determined that public services impact from implementation of the approved Housing Element Update would be less than significant with no mitigation required (Section 4.15, City of Pico Rivera
Zone Code Amendments and Zone Reclassification
38 Public Services). Implementation of the approved Housing Element Update would result in an increase in residential and commercial development, and thus, would increase demand for fire and police protection services and facilities, school facilities, and recreation facilities. However, 68 of all 69 sites are currently developed and are being serviced adequately by existing fire and police services. Housing Element Update implementation would result in intensification of development and/or change of use, or construction on previously vacant sites. However, all candidate housing sites are within urbanized areas, surrounded by development, and served by the Los Angeles County Fire Department (LACFD) and Los Angeles County Sheriff’s Department (LASD). Regarding school facilities, future applicants would be subject to school developer fees from the El Rancho Unified School District (ERUSD) and Montebello Unified School District (MUSD). The approved Housing Element Update determined that payment of the developers’ fees would provide an adequate financial base to construct and equip new and existing schools, and would be deemed full and complete mitigation of the impacts pursuant to Government Code Section 65995(3)(h).

Impacts related to parks and recreation may be found below in Section 16, Recreation. In addition, the 2022 IS-MND determined that future development resulting in population growth would incrementally increase demand for libraries. However, the Los Angeles County Library system has developed a Strategic Plan that identifies goals and objectives including financial management and fundraising strategies to maintain and enhance library facilities to meet future demands. Therefore, increased demand would not be substantial or such that it would warrant construction of a new facility.

While the 2022 IS-MND also acknowledges that an additional 400 ADUs would be developed atop the 1,332 housing units, it does not analyze a full buildout of 1,732 housing units. Therefore, this analysis considers impacts associated with the development of an additional 400 ADUs for a total of 1,732 housing units under the Proposed project. Future housing development facilitated by the proposed Zone Amendment and Reclassification and the resulting population growth of approximately 6,426 persons, would increase the use of existing public facilities. Development under the proposed Project would occur on the same candidate housing sites which are currently served by LACFD and LASD, which would place an incrementally higher demand on police and fire services in the city compared to the approved Housing Element Update due to the increase in the projected population, and the potential for developers to utilize the R-40 Zoning Overlay increasing building density. However, all future housing development facilitated by the Housing Element Update would be subject to the City’s development review process, and adherence to 2019 California Fire Code and Municipal Code Section 15.44, Fire Code. Compliance with the established regulatory framework would minimize impacts to fire protection services. In addition, future housing development facilitated by the proposed Project would be required to submit a will-serve letter or service questionnaire to the Police Department in conjunction with development applications to ensure that police protection services are available to serve the proposed housing development.

The City is served by the ERUSD and MUSD, which provide public education for grades kindergarten through 6 and grades 7 through 12, respectively. Future housing development facilitated by the proposed Zone Amendment and Reclassification and the resulting population growth of approximately 6,426 persons would incrementally increase the demand for school services. Similar to the approved Housing Element Update, any future housing development facilitated by the Housing Element Update would be required to comply with SB 50 requirements, which allow school districts to collect impact fees from developers of new residential projects to offset the cost of new development pursuant to Government Code Section 665995(3)(h). Similar to the approved Housing Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 39 Element Update, the Los Angeles County Library system has developed a Strategic Plan that identifies long-term goals and objectives to maintain and enhance library facilities to meet future demands.

Overall, while the proposed Zone Amendment and Reclassification analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, no new or expanded public service facilities would be required. The proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to public services and would be consistent with the impact analysis provided in the 2022 approved Housing Element Update ISMND.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.16 Recreation
The 2022 IS-MND determined that impacts to recreational facilities from implementation of the approved Housing Element Update would be less than significant with mitigation required (Section

4.16, Recreation,). As of 2021, the City has a parkland ratio of 1.9 acres per 1,000 residents.

General Plan Policy 10.7-1 Parks Master Plan strives to attain a parks standard of three acres per 1,000 people, meaning that the City currently has a deficit of recreational facilities. Future housing development facilitated by the approved Housing Element Update and the resulting population growth of approximately 4,942 persons, which would incrementally increase the use of existing recreational facilities. To avoid the overuse of existing recreational facilities, such that substantial physical deterioration would occur, payment of Park Land Dedication or In-Lieu fees would be required to mitigate potential effects to a less than significant level. The approved Housing Element Update IS-MND also determined that if construction of recreational facilities is warranted, that proposal would be subject to the City’s development review process and CEQA evaluation. A less than significant impact would occur regarding the construction and expansion of recreational facilities.

The 2022 IS-MND found that the following measure shall be implemented as standard condition/condition of approval for future housing projects:

Measure SC REC-1: The applicant shall in-lieu of dedicating park land pay park fees equal to the value of the land prescribed for dedication in Municipal Code Section

17.36.190 hereof in an amount determined in accordance with the provisions of Section 17.36.230.

To avoid the overuse of existing recreational facilities, such that substantial physical deterioration would occur, future housing developments would be subject to General Plan Policy 10.7-3, New Development, which requires new residential development, which include a subdivision, to dedicate land and/or contribute in-lieu fees at a standard of 3 acres per 1,000 population, and contribute park development fees, to finance acquisition, development, improvement, and maintenance of park and recreational facilities. Municipal Code Chapter 17.36, Article II, Park Land Dedication or InLieu Fees identifies that park and recreation impact land dedications and/or fees are applicable as a condition of approval of a final tract map. Payment of fees helps fund the acquisition and development of new or rehabilitating existing park and recreational facilities needed to accommodate demands created by the addition of residential dwelling units. Adherence to mandatory permit requirements and regulations for providing recreation would support the City’s goals for providing sufficient recreation opportunities for residents. The proposed Zone Amendment and Reclassification would utilize Measure SC REC-1 to mitigate potential impacts to recreational facilities to a less than significant level.

Future housing development facilitated by the proposed Project and the resulting population growth of approximately 6,426 persons would incrementally increase demand for park and recreation land by approximately 19.28 acres (based on General Plan Healthy Communities Element Policy 10.7-3, New Development). All future housing development facilitated by the proposed Zone Amendment and Reclassification would be subject to the City’s development review process and required to demonstrate consistency with General Plan Policy 10.7-3. If future development of recreational facilities is required, that proposal would be subject to the City’s development review process and CEQA evaluation to determine whether adverse effects on the environment. Therefore, a less than significant impact would occur regarding the construction or expansion of recreational facilities.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting recreation. As a result, the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to parks or recreation and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
Less than Significant with Mitigation (Same as Approved Housing Element Update)

4.17 Transportation
The 2022 IS-MND determined that transportation impacts associated with implementation of the approved Housing Element Update would be less than significant (Section 4.17, Transportation, of Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 41 the 2022 IS-MND). The approved Housing Element Update does not include any goals, policies, or implementation programs that would conflict with plans or other regulations that address the circulation system, including roadways, transit, bicycle, pedestrian, and equestrian facilities. Future development projects would be reviewed on a case-by-case basis to ensure consistency with applicable regulations that address the circulation system, including regulations related to VMT and emergency access. Future housing development facilitated by the approved Housing Element Update would be required to comply with several General Plan policies which directly aim to reduce VMT. Any traffic demand management (TDM) measures required for mitigation would be required to comply with Los Angeles County’s VMT guidelines.

Since future housing development facilitated by the approved Housing Element Update would use existing roadways that are connected and adjacent to the existing transportation network, hazards due to a geometric design feature or incompatible uses are not anticipated. All future housing development on the candidate housing sites with the potential to substantially increase transportation-related hazards would be subject to the City’s development review and required to comply with applicable building and fire safety regulations required for the design of new housing and emergency access, as wells as and all State and local requirements for avoiding construction and operations impacts related to design and incompatible uses. In regard to emergency access, the City has adopted the California Fire Code, which sets standards for road dimension, design, grades, and other fire safety features. More stringent California Building Code standards apply regarding new construction and development of emergency access issues associated with earthquakes, flooding, climate/strong winds, and water shortages. Therefore, compliance with the code requirements would ensure adequate access issues, including emergency access. As a result, implementation of the approved Housing Element Update would result in a less than significant impact.

The City has adopted the Los Angeles County VMT Thresholds (Fehr and Peers 2020). The Steering Committee recommends that the County define VMT impacts for land use projects and plans based on the Air Resources Board target of 16.8 percent. A 16.8 percent VMT reduction threshold sets a higher standard than the suggested Office of Planning and Research threshold of 15 percent and would allow the County to align with state climate goals (Fehr and Peers 2020). A project would have a significant impact if the VMT rate for the plan would exceed 16.8 percent below the applicable baseline VMT rate.

A VMT Analysis was prepared by Translusions, Inc. for the proposed Zone Amendment and Reclassification (included as Appendix B). The VMT Analysis utilizes the SCAG RTP/SCS model’s base year of 2016 and horizon year of 2040. Through discussions with the City, the analysis was City of Pico Rivera
Zone Code Amendments and Zone Reclassification
42 conducted for the years 2020 and 2040. The analysis used the following thresholds to determine whether the proposed Zone Amendment and Reclassification would result in a significant Project generated VMT:

The baseline Project generated VMT per service population (VMT/SP) exceeds the baseline VMT/SP for the City, or
The cumulative Project generated VMT /SP exceeds the future year VMT/SP for the City.

Project-generated VMT was determined under the 2040 horizon to account for development under the proposed Project. It was determined that the baseline (2020) plus Project VMT/SP is 10.83 miles while the without Project VMT/SP is 10.88 miles. The Project related VMT/SP is 9.67, which is less than the baseline VMT/SP for the City (see Appendix B for complete results). Therefore, the Project has a less than significant VMT impact under baseline conditions. In regard to projected VMT, the year 2040 plus Project VMT/SP is 11.23 miles while the without Project VMT/SP is 11.30 miles. The Project related VMT/SP is forecasted to be 9.67, which is below the baseline VMT/SP for the City (Appendix B). Therefore, the VMT/SP is estimated to decrease with buildout of the proposed Project thereby resulting in fewer trips (i.e., mobile noise) when compared to buildout under existing land use designations, and VMT impacts would be less than significant. Additionally, a cumulative impact would occur if there would be a net increase in total regional VMT.

The total VMT in the City in the horizon year 2040 without the proposed Zone Amendment and Reclassification would be 2,564,970 (Appendix B). With the proposed Project, the total VMT for the City would be 2,659,363 (Appendix B). Therefore, there would be an increase in total VMT of 94,393 and may be considered significant. However, similar to the approved Housing Element Update, future housing development facilitated by the proposed Project would be required to comply with several General Plan policies which directly aim to reduce VMT. Given that the housing sites of the proposed Project have not changed, all candidate housing sites would still be located in urban and developed areas placing residents closer to employment and commercial areas, further increasing opportunities to reduce VMT and increase the ease of walking, cycling, and use of public transit.

In addition, the zone code amendments and reclassification of the proposed Zone Amendment and Reclassification would be consistent with Measure T-1 (Increase Residential Density) of the California Air Pollution Control Officers Association’s (CAPCOA) Handbook for Analyzing Greenhouse Gas Emission Reductions, Assessing Climate Vulnerabilities, and Advancing Health and Equity, and therefore could have a reduction of 0.22 percent for every one percent increase in residential density (CAPCOA 2021). Applying this reduction indicates the proposed Zone Amendments and Reclassification would decrease overall VMT produced by the proposed Project. Cumulative transportation impacts would be reduced to a less than significant level.

Similar to the approved Housing Element Update, future housing projects facilitated by the proposed Zone Amendment and Reclassification would be required to comply with General Plan Circulation Element Policy 5.2-10, Traffic Studies, which requires the preparation of site-specific traffic studies for new development proposals that are determined by the City to have the potential to impact traffic. Future housing development facilitated by the proposed Project would be required to comply with applicable building and fire safety regulations required for the design of new housing and emergency access; and would be required to adhere to all State and local requirements for avoiding construction and operations impacts related to design and incompatible uses. As a result, future housing development facilitated by the proposed Project would not substantially increase hazards due to design features or incompatible uses.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 43 Similar to the approved Housing Element Update, the proposed Project must be in compliance with the California Fire Code and California Building Code regarding new construction and development of emergency access issues associated with earthquakes, flooding, climate/strong winds, and water shortages. Therefore, compliance with the code requirements would ensure adequate access issues, including emergency access. Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting transportation.

Therefore, the proposed Zone Amendment and Reclassification would not result in new or substantially more severe impacts to transportation, and the proposed Project would therefore be consistent with the 2022 IS-MND.

Conclusion
Less than Significant Impact (Same as Approved Housing Element Update)

4.18 Tribal Cultural Resources
Chapter 532 Statutes of 2014 (i.e., AB 52) requires that lead agencies evaluate a project’s potential impact on “tribal cultural resources.” In compliance with PRC Section 21080.3.1(b), the City has provided formal notification to California Native American tribal representatives identified by the California Native American Heritage Commission. Native American groups may have knowledge about cultural resources in the area and may have concerns about adverse effects from development on tribal cultural resources as defined in PRC Section 21074. The City contacted a total of ten (10) tribes and received a response from one, the Gabrieleno Band of Mission Indians – Kizh Nation. While the approved Housing Element Update does not propose any development or ground-disturbing activities such as grading or excavation, it can be assumed that future housing development on the candidate housing sites facilitated by the approved Housing Element Update could directly or indirectly impact undiscovered subsurface tribal cultural resources through such activities. The likelihood of encountering tribal cultural resources is greatest where sites that have been minimally excavated in the past (e.g., undeveloped parcels, vacant lots, and lots containing undeveloped areas). In the likelihood that future housing development would impact tribal resources, compliance with the Measure SC TCR-1 addresses actions associated with tribal resources would mitigate potential impacts.

The 2022 IS-MND found that the following measure shall be implemented as standard condition/condition of approval for future housing projects:

Measure SC TCR-1 Unanticipated Discovery of Tribal Cultural and Archaeological Resources:

Upon discovery of any tribal, cultural, or archaeological resources during ground-disturbing activities, the applicant shall immediately cease such activities in the immediate vicinity. The find will then be assessed by a qualified archeologist retained by the Applicant and a tribal monitor/consultant approved by the consulting tribe. The applicant shall promptly notify the Director of Community and Economic Development to the discovery of resources. If the resources are Native American in origin, the City of Pico Rivera
Zone Code Amendments and Zone Reclassification
44 consulting tribe shall coordinate with the landowner regarding treatment and curation of these resources. Typically, the tribe will request preservation in place or recovery for educational purposes. At the direction of the qualified archaeologist and tribal monitor/consultant, and in coordination with the Community and Economic Development Division, work may continue on other parts of the affected site while evaluation and, if necessary, additional protective measures are completed at the affected portion of the site pursuant to State CEQA Guidelines Section 15064.5 [f]. If a resource is determined by the qualified archaeologist to constitute a “historical resource” or “unique archaeological resource,” time and funding to allow for sufficient implementation of avoidance measures must be made available.

The treatment plan established for the resources shall be in accordance with State CEQA Guidelines Section 15064.5(f) for historical resources.

Preservation in place (i.e., avoidance) is the preferred manner of treatment upon identification of unique archeological resources (Public Resources Code Section 21083.2(b)). If preservation in place is not feasible, treatment may include implementation of archaeological data recovery excavations to remove the resource along with subsequent laboratory processing and analysis. All tribal cultural resources shall be returned to the consulting tribe.

Any historic archaeological material that is not Native American in origin shall be curated at a public, non-profit institution with a research interest in the materials. Acceptance and curation of the historic archeological materials will be at the discretion of the institution. If no institution accepts the archaeological material, they shall be offered to the consulting tribe or the Pico Rivera History and Heritage Society for educational purposes.

While the candidate housing sites would remain the same as those in the approved Housing Element Update, the proposed Zone Amendment and Reclassification may still have an impact on tribal cultural resources. Development of the proposed Project would require the incorporation of Measure SC CUL-1 (noted above) from the approved Housing Element Update. In addition, all future housing development facilitated by the Housing Element Update would be subject to the City’s development review process and would be required to comply with federal, State, and local requirements for the protection of tribal cultural resources. This includes compliance with CEQA Section 21074 and the City’s Environmental Resources Element, Goal 8.7, which aims to preserve important historical, archaeological, and paleontological resources that contribute to the City’s identity and character. Compliance with this mitigation measure would ensure that impacts to tribal cultural resources would be less than significant.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting tribal cultural resources. Therefore, the proposed Zone Amendment and Reclassification would not introduce new impacts or substantially increased impacts related to tribal cultural resources and would be consistent with the impact analysis provided in the 2022 IS-MND.

Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 45 Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.19 Utilities and Service Systems
The 2022 IS-MND determined that utilities and service systems impacts from implementation of the approved Housing Element Update would be less than significant with mitigation required (Section

4.19, Utilities and Service Systems, of the 2022 IS-MND). Pico Rivera is served by the City of Pico Rivera Water Authority (PRWA), Pico Water District (PWD) and San Gabriel Valley Water Company (SGVWD). All candidate housing sites are located in the services area of either PRWA, PWD or SGVWD. In addition, all but one candidate housing site is currently developed with existing water infrastructure. The approved Housing Element Update is not anticipated to require or result in the relocation or construction of new or expanded water facilities that could cause significant environmental effects. The City of Pico Rivera’s Sewer Division is responsible for the collection of wastewater in the City and delivery to the trunk sewer mains of the Los Angeles County Sanitation Districts (LACSD). The forecasted population growth induced by the approved Housing Element Update is 4,942 persons. Additionally, the City’s forecast population including future housing development facilitated by the approved Housing Element Update of approximately 69,642 persons would be 542 persons greater than SCAG’s forecast population of 69,100 persons by 2040.

However, this difference in persons is less than one percent of SCAG’s forecast population by 2040 and would not be large enough of a change to significantly impact existing wastewater facilities.

The 2022 IS-MND also determined that project implementation would not require construction or relocation of new or expanded storm drainage facilities as the majority of the candidate housing sites are currently developed and surface flows are directed towards the City’s existing facilities.

Additionally, development facilitated by the proposed Project would be compliant with all applicable City policies regarding storm drainage such as Municipal Code Chapter 16.04 and the City’s Urban Greening Plan. Similarly, the approved Housing Element Update would have a less than significant impact on electrical power, natural gas, and telecommunication facilities as the approved Housing Element Update would be required to be consistent with the City’s various programs aimed at ensuring adequate supplies and service infrastructure.

Future housing development would be required to comply with Measure SC UTI-1, which mandates the incorporation of water conservation practices, designs, and technology into proposed structures. Future development satisfying certain criteria would be required to prepare a Water Supply Assessment (WSA) in order to verify sufficient water supply is available to meet the development’s water demand. Future housing development would be required to submit specific development plans to the City, PRWA, PWD and/or SGVWD substantiating that adequate water supplies would be available. Future housing development would also be subject to development review and required to comply with requirements related to wastewater treatment during construction and operations, including the City’s Sanitary Sewers and Industrial Waste Ordinance (Municipal Code Section 13.28.010) and the Construction General Permit. The City levies connection fees for new or expanded sewer connections, including those to new development. These connection fees help fund the costs associated with providing wastewater facility capacity to both new users requiring new connections, as well as existing users requiring additional capacity.

Compliance with the City’s regulations regarding the provision of sewer services would ensure the City has capacity to accommodate development of the approved Housing Element Update.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
46 The approved Housing Element Update determined that future housing development would be subject to the City’s development review process and be required to adhere to all federal, State, and local requirements for solid waste reduction and recycling. Considering these requirements, the approved Housing Element Update’s implementation would not generate solid waste in excess of State or local standards, or in excess of local infrastructure’s capacity. In addition, the approved Housing Element Update would have no impact on regulations regarding solid waste, as development facilitated by the approved Housing Element Update would comply with all applicable policies regarding solid waste such as the CalGreen Code, AB 939, and SB 341.

The 2022 IS-MND found that the following measures shall be implemented as standard conditions/conditions of approval for future housing projects:

Measure SC UTI-1 Applicant shall include water conservation practices, designs, and technology into the proposed structures. These shall include low-flow showerheads, faucets, appliances, and toilets.

Measure SC UTI-2 The City shall not approve development beyond anticipated 2025 growth projections until securing additional water supplies or demonstrating in the UWMPs or project-specific Water Supply Assessment that water supply amounts are available to meet existing and project water demand.

Similar to the approved Housing Element Update, all candidate housing sites under the proposed Zone Amendments and Reclassification are located in the services area of either PRWA or PWD. In addition, all but one candidate housing site is currently developed with existing water infrastructure. The proposed Project is not anticipated to require or result in the relocation or construction of new or expanded water facilities that could cause significant environmental effects.

In addition, implementation of the proposed Project would not require construction or relocation of new or expanded storm drainage facilities as the majority of the candidate housing sites are currently developed and surface flows are directed towards the City’s existing facilities. Similar to the approved Housing Element Update, the proposed Project would have a less than significant impact on electrical power, natural gas, and telecommunication facilities as the Project would be required to be consistent with the City’s various programs aimed at ensuring adequate supplies and service infrastructure.

The proposed Zone Amendments and Reclassification is anticipated to require of approximately 198 acre-feet (AF) of water per year (Appendix A). According to the PWD 2020 Urban Water Management Plan (UWMP), and as shown in Table 6 through Table 8 below, PWD would have adequate water supplies through 2045 in normal, single dry year, and multiple dry year conditions (PWD 2021).

PWD has reduced its reliance on imported water supplies, through the Water Replenishment District of Southern California’s (WRD) replacement of imported water with recycled water for groundwater replenishment purposes. WRD primary water supply is collected from the Central Basin. In each drought cycle the Central Basin has been managed to maintain water levels.

Therefore, based on historical and on-going management practices, PWD will be able to rely on the Central Basin for adequate supply over the next 25 years under single dry years and a five consecutive year drought periods. In addition, the proposed Zone Amendments and Reclassification would incorporate Measures SC UTI-1 and UTI-2 to ensure that water would be used efficiently, and that development facilitated by the Project would not have a significant impact on supplies. Impacts to water supply and reliability would be less than significant.

City of Pico Rivera
Zone Code Amendments and Zone Reclassification
48 Wastewater creation is conservatively assumed to be 100 percent of total water consumption. Thus, it can be anticipated that the proposed Zone Amendments and Reclassification would result in approximately 64,558,222 gallons (or 198 AF) of wastewater per year, or 176,872 gallons of wastewater per day. Similar to the approved Housing Element Update, wastewater from the proposed Project would be collected locally and delivered to the regional trunk lines, and wastewater flows south toward LASCD’s Los Coyotes Water Reclamation Plant in the City of Cerritos. Los Coyotes Water Reclamation Plant currently provides primary, secondary, and tertiary treatment for a design capacity of 37.5 million gallons of wastewater per day. The proposed Zone Amendments and Reclassification would utilize approximately 0.5 percent of the Los Coyotes Water Reclamation Plant current daily capacity. Future housing development under the proposed Project would be subject to development review and would be required to comply with requirements related to wastewater treatment during construction and operations, including the City’s Sanitary Sewers and Industrial Waste Ordinance (Municipal Code Section 13.28.010) and the Construction General Permit. The City levies connection fees for new or expanded sewer connections, including those to new development (Municipal Code Sections 13.16.120 and 13.16.140). These connection fees help fund the costs associated with providing wastewater facility capacity to both new users requiring new connections, as well as existing users requiring additional capacity. Considering these requirements, and the available capacity previously discussed, no new expansions of infrastructure facilities are required, and no direct physical impact on the environment would occur. Therefore, impacts would be less than significant.

Solid waste generated within the City is collected by NASA Services Inc. The residential, commercial, and industrial services include curbside collection of waste, commingled recyclables, and green waste. Pico Rivera has a number of waste diversion programs in place to minimize the need for landfill disposal of solid wastes, including a Demolition and Recycling ordinance in compliance with AB 939. The proposed Project would generate approximately 433 tons of water per year (Appendix A). It is anticipated that solid waste from future housing development would be disposed of at the closest landfills: Savage Canyon Landfill, Scholl Canyon Landfill, and the Azusa Land Reclamation Company Landfill. The Savage Canyon Landfill is permitted to receive 350 tons per day and has a remaining capacity of approximately four million tons. The Scholl Canyon Landfill is permitted to receive 3,400 tons per day and has a remaining capacity of approximately four million tons. The Azusa Land Reclamation Company Landfill is permitted to receive 8,000 tons per day and has a remaining capacity of approximately 59 million tons (County of Los Angeles Public Works 2019). All solid waste facilities have adequate remaining capacity to accommodate development facilitated by the proposed Zone Amendments and Reclassification. Impacts would be less than significant.

Regulations specifically applicable to the proposed Project include the California Integrated Waste Management Act of 1989 (AB 939), Section 4.408 of the CalGreen Code, and SB 341, which requires multi‐family residential development and commercial uses to implement recycling programs. The Integrated Waste Management Act, which requires every city and county in the State to prepare a Source Reduction and Recycling Element (SRRE) to its Solid Waste Management Plan, identifies how each jurisdiction will meet the State’s mandatory waste diversion goal of 50 percent by and after the year 2000. The diversion goal has been increased to 75 percent by 2020 by SB 341. The 2019 CalGreen Code Section 4.408 requires preparation of a Construction Waste Management Plan that outlines ways in which the contractor would recycle and/or salvage for reuse a minimum of 65 percent of the nonhazardous construction and demolition debris. As previously noted, the Project would not result in direct housing construction but would facilitate future housing development.

During the construction phase of future housing development, projects would comply with the CalGreen Code through the recycling and reuse of at least 65 percent of the nonhazardous Environmental Checklist and Impacts of the Proposed Zone Amendments and Reclassification Addendum to the Pico Rivera 6th Cycle Housing Element Update IS-MND 49 construction and demolition debris from the Project site. No conflict with statutes and regulations related to solid waste would occur.

Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact affecting utilities and service systems. As a result, the proposed Zone Amendments and Reclassification would not introduce new impacts or substantially increased impacts related to utilities and other service systems and would be consistent with the impact analysis provided in the 2022 IS-MND for the approved Housing Element. Impacts would be less than significant.

Conclusion
Less than Significant Impact with Mitigation (Same as Approved Housing Element Update)

4.20 Wildfire
The approved 2022 IS-MND determined that the approved Housing Element Update would have no impact to any emergency response or evacuation plans, would not exacerbate wildfire risks, and would not expose people or structures to significant risk of flooding or landslides. According to CalFire Fire Hazard Severity Zone Map for Los Angeles County, the City is in a Non-Very High Fire Hazard Severity Zone (Non-VHFHSZ) within a local responsibility area (LRA). No candidate housing sites are near a fire hazard severity zone. There would be no impact to wildfire and mitigation would not be required.

Similar to the area of the approved Housing Element Update, the area for the proposed Zone Amendments and Reclassification includes urbanized development with residential uses. All 69 candidate housing sites would remain the same as in the approved Housing Element Update. The City is in a Non-VHFHSZ within a LRA. No candidate housing sites are near a fire hazard severity zone. Although the proposed Project analyzes the additional 400 ADUs not previously analyzed in the approved Housing Element Update, the additional residential units under the proposed Project would not result in a new significant impact regarding wildfire. Therefore, the proposed Project would not introduce new impacts or substantially increased impacts related to wildfire and would be consistent with the impact analysis provided in the 2022 IS-MND.

Conclusion
No Impact (Same as Approved Housing Element Update)

50 5 Conclusion
As discussed in detail in Section 4, Environmental Checklist and Impacts of the Proposed Project, potential impacts associated with the proposed Zone Amendments and Reclassification are consistent with potential impacts characterized and mitigated for in the 2022 IS-MND for the approved Housing Element Update. Substantive revisions to the 2022 IS-MND are not necessary because no new significant impacts or impacts of substantially greater severity than previously described would occur as a result of the proposed Project. Therefore, the following determinations have been found to be applicable:
 No further evaluation of environmental impacts is required for the proposed Project;  No subsequent EIR or MND is necessary per Section 15162 of the CEQA Guidelines; and  This Addendum is the appropriate level of environmental analysis and documentation for the proposed Project in accordance with Section 15164 of the CEQA Guidelines.

Pursuant to Section 15164(c) of the CEQA Guidelines, this Addendum will be included in the public record for the approved Housing Element Update. Documents related to this Addendum will be available at the City of Pico Rivera located at 6615 Passons Boulevard, Pico Rivera, California 90660.

Pico Rivera Zone Code Amendments and Zone Reclassification Project Detailed Report, 2/24/2023 62 / 68

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 13.1 annual days of extreme heat Extreme Precipitation 4.85 annual days with precipitation above 20 mm Sea Level Rise 0.00 meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider different increments of sea level rise coupled with extreme storm events. Users may select from four model simulations to view the range in potential inundation depth for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 50 meters (m) by 50 m, or about 164 feet (ft) by 164 ft.

Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Subject: VMT Analysis for the City of Pico Rivera 6th Cycle Housing Element Code Amendments Dear Michael:

Translutions, Inc. (Translutions) is pleased to provide this letter discussing the Vehicle Miles Traveled (VMT) analysis for the proposed Housing Element Code Amendments for the City of Pico Rivera (the Project). This analysis is consistent with the requirements for a VMT analysis established by the State of California to evaluate impacts to transportation under CEQA. Since this is a housing element update, this memorandum evaluates the change in VMT per Service Population under “without” and “with” project conditions. The VMT analysis for the project was conducted using year 2020 and 2040 data sets from the 2016 Southern California Association of Governments Regional Transportation Plan/Sustainable Communities Strategies (SCAG RTP/SCS) travel model (model).

PROJECT DESCRIPTION
The Housing Element is required to demonstrate the City’s capacity to plan for its share of housing growth. The City’s share of housing is determined by the Southern California Association of Governments (SCAG) via the Regional Housing Needs Assessments (RHNA).

The RHNA is the number of units that a city is required to plan for (not develop) by identifying sites throughout the City. For the 2021- 2029 Housing Element planning period, SCAG assigned the City 1,024 units. After the acreage calculations, 1,333 units were identified by the City. The area wise breakdown and number of units are included in Attachment A.

ANALYSIS METHODOLOGY
MODELING YEARS (2020 AND 2040)
The SCAG RTP/SCS model’s base year is 2016 and horizon year is 2040. However, based on discussions with the City, the proposed analysis was conducted for years 2020 and 2040. The model includes a 2020 dataset from SCAG which was used for the analysis.

MODELING METHODOLOGY
The SCAG RTP model uses a two-tier traffic analysis zone (TAZ) system – Tier 1 zones and Tier 2 zones. Two or more Tier 2 zones make up a Tier 1 zone. The model utilizes Tier 2 zone system for modeling steps such as trip generation, trip distribution, and mode choice while it uses Tier 1 zone system for assignment purposes. Given the inability to perform zone splits in the SCAG RTP model and based on how the guidelines require evaluation of plans and programs, the additive method was used for the analysis. Under this method, project related SED was added to the existing (or future) SED of the TAZs to evaluate with project VMT.

MODEL SOCIOECONOMIC DATA
The model consists of both residential (households and population) and non-residential land uses (employment by type/category) as inputs. For households, the travel model uses household characteristics such as household income, household size, and household workers etc., to determine the household travel patterns. The number of households by dwelling unit type were based on the Project information provided by the City. Further, based on discussions with the City, to account for multiple families living in the same unit, 400 additional households were included . Therefore, this evaluation is based on 1,732 units.

The average household size from 2016 SCAG RTP/SCS model for each TAZ was maintained and carried over to the number of new dwelling units proposed as part of the Project. Table A shows the change in households and population that is forecast to occur at each 2/8/2023 (Q:\Rincon - Pico Rivera Housing Element\VMT Letter.docx) 2 the transportation solutions company...

TAZ because of the Project. As shown on Table A, the Project will result in an increase of 1,732 households which would translate into a population increase of 6,171.

MODEL RUNS AND OUTPUTS
Model Runs were conducted for the 2020 and 2040 conditions for both without project and with project conditions with the above discussed SED and networks. Consistent to standard modeling practice, each model was run with conditions that at least 5-loops1 be run or until a convergence of 0.01 (i.e., 1.0%) is achieved. Detailed model outputs are shown in Attachment B.

VMT SIGNIFICANT IMPACT THRESHOLDS & RESULTS
For General Plans and Specific Plans, the following would result in a significant project generated VMT:

1. The baseline project generated VMT per service population exceeds the baseline VMT per service population (VMT/SP) for the City, or
1 Models are run with feedback loops wherein the output of one run is becomes the basis of the next run. In this process, the predicted speeds are used to re-compute highway and transit travel times, and the entire model sequence is repeated until input and output speeds are generally consistent with each other. Each iteration is referred to as a loop. The percentage change in total travel cost between one iteration and the next is referred to as “convergence”. A convergence of 0.01 means that the change in travel cost between one run and the next is 1%. Models in the SCAG region are generally run for 5 loops or a convergence of 0.01. 2/8/2023 (Q:\Rincon - Pico Rivera Housing Element\VMT Letter.docx) 3 the transportation solutions company...

2. The cumulative project generated VMT per service population exceeds the future year VMT per service population (VMT/SP) for the City.

Therefore, the project VMT per 2 The average vehicle trip distances are not the trip lengths generated by the net new development directly, but the effect on vehicle trip and VMT for the whole project area. The effect of adding more housing to the study area will reduce trip length on average. In order to compute the average vehicle distance, the net new VMT should be divided by the net new vehicle trips, but this should not be interpreted to mean that the new development will have markedly different patterns than the existing development; rather the effects on travel of adding housing will be to bring everyone’s average down (including existing uses). 2/8/2023 (Q:\Rincon - Pico Rivera Housing Element\VMT Letter.docx) 4 the transportation solutions company...
service population is less than the VMT/SP under without project conditions and therefore, the project has a less than significant VMT impact under baseline conditions.

FINDINGS & CONCLUSION
The results of the VMT analysis shows that the project related VMT/SP is lower than the VMT/SP for the City. In fact, the Project reduces the Citywide VMT/SP under both analysis conditions. Therefore, the Project has a less than significant impact under both the baseline and future year conditions.
