6. Climate Risk Detailed Report

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 9.03 annual days of extreme heat Extreme Precipitation 3.50 annual days with precipitation above 20 mm Sea Level Rise 0.00 meters of inundation depth
Wildfire 1.31 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. City Council 26 – 180 1/16/2024 Vista Charter School Expansion Detailed Report, 7/26/2023 58 / 63
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.

Air Quality Degradation 0 0 0 N/A
The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.

The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

VISTA HERITAGE GLOBAL ACADEMY EXPANSION TRIP

GENERATION ASSESSMENT
Urban Crossroads, Inc. is pleased to provide the following Trip Generation Assessment for the Vista Heritage Global Academy Expansion development (Project), which is located at 601 North Fairview Street in the City of Santa Ana.

The purpose of this assessment is to describe the proposed Project trip generation and provide a comparison to the existing building zoned as Light Manufacturing (M1).

PROPOSED PROJECT
The Project site currently contains an existing 5,837 square-foot industrial building that will be converted into an administrative office building. A 12,186 SF building was demolished and redeveloped into parking spaces as part of the expansion. In addition, the applicant is proposing to improve the site with 17,497 square feet of student outdoor spaces, on-site parking, and landscaping. Vista Heritage Global Academy is not increasing the maximum number of students with this expansion.

TRIP GENERATION
Trip generation represents the amount of traffic which is both attracted to and produced by a development. Determining traffic generation for a specific project is therefore based upon forecasting the amount of traffic that is expected to be both attracted to and produced by the specific land uses being proposed for a given development. In order to develop the traffic characteristics of the existing land use and the proposed Project, trip-generation statistics published in the ITE Trip Generation Manual (11th Edition) were used.

EXISTING USE
As noted previously, the site is designated as Light Manufacturing (M1) and is currently developed with a 5,837 square foot industrial building on-site. The trip generation for the existing use is summarized in Table 1. As shown in Table 1, the existing industrial building generates a total of 28 two-way trips per day with 4 AM peak hour trips and 4 PM peak hour trips.

TABLE 1: EXISTING USE TRIP GENERATION

PROPOSED PROJECT
The proposed Project includes the redevelopment of the existing building into a 5,764 school district office building. The trip generation summary illustrating daily, and peak hour trip generation estimates for the proposed Project are also summarized in Table 2. The proposed Project is anticipated to generate 84 two-way trips per day with 14 AM peak hour trips and 12 PM peak hour trips.

TABLE 2: PROPOSED PROJECT TRIP GENERATION SUMMARY

TRIP GENERATION COMPARISON
Table 3 compares the trip generation of the proposed Project to the existing use (currently adopted). The resulting net change in trips is also identified in Table 3 and has been calculated by subtracting the existing use from the proposed Project. As shown, the Project is anticipated to generate a net increase of 56 two-way trips per day, 10 more AM peak hour trips, and 8 more PM peak hour trips as compared to the existing use.

TABLE 3: TRIP GENERATION COMPARISON

FINDINGS
The development of the proposed Project (school district office) is anticipated to generate more trips than the existing (currently approved) industrial use. The net increase in trip generation and total trips generated are below 50 peak hour trips. As such, additional traffic analysis beyond this trip generation assessment does not appear to be necessary as the effects on transportation operations (level of service) are not significant.

DISCUSSION
Project Description
The amendment application will allow the rezoning of the subject property from M1 to SD82 and help facilitate the conversion of a 5,837-square-foot industrial building into an administrative office that will serve Vista Heritage Charter School. Furthermore, the proposed administrative office will serve as headquarters for Vista Heritage Charter School that will oversee a total of six charter schools and it will employ a total of ten individuals that are currently employed at different Vista Heritage Charter Schools. The SD-82 boundaries would be expanded to include the subject property (601 N. Fairview Street or Parcel 4 as illustrated on Exhibit 9), which is approximately 39,437 square feet and located north of the existing SD-82 zoning district, and adjacent to Fairview Street and the Pacific Electric right-of-way (ROW).

As part of the overall scope of work, the applicant also proposes various site improvements at the subject site on Parcel 4, including improved landscape in the parking lot; a façade remodel to the existing 5,837-square-foot industrial building that is proposed to be converted into an office; construction of a new 2,297-square-foot garden; and new gates to enclose the garden. The new proposed garden will be located in the rear of the existing industrial building to be converted into an administrative office within a gated area and it will serve the Vista Heritage Charter School administrative office employees.

Additionally, the building improvements for the converted office building will include façade modifications to create new glass windows and doors; removal of the garage doors; and the creation of new offices, conference rooms, reception area, storage rooms, and an employee breakroom. Furthermore, the scope of work includes improvements at the Vista Heritage Charter School location (2501 W. Fifth Street or Parcel 2 as illustrated on Exhibit 9) for a new outdoor play area that totals 12,012 square feet and gates to enclose the play area. The existing indoor gym and office spaces will remain for indoor recreation and physical education for the students and administrative purposes, without any proposed changes. The outdoor play area will be located directly adjacent to Vista Heritage Charter School on the north side of the building and will serve as a play area for the school’s students during the school’s regular business hours. Lastly, the site improvements include a metal wire fence that will be installed by Orange County Transit Authority (OCTA) along north property line adjacent to the OC Street Car tracks.

At this time, there is no additional square footage being proposed. All the proposed improvements will fall within the existing building. The current student enrollment is 840 students and there is no expansion of student enrollment or school capacity proposed as part of the project.

Project Background
On October 6, 2008, the City Council approved several entitlements for the Civic Center Business Park located at the northeast corner of Fifth Street and Fairview Street, including Amendment Application No. 2008-06 (Ordinance No. NS-2777). The amendment application allowed for a zone change of the business park site from M1 to SD-82. The request was initiated by the Templo Calvario Assembly of God Church, which at the time was proposing to expand their worship facilities by constructing a larger sanctuary at 2501 West Fifth Street. However, the specific development still allowed for the retention of the existing office, retail, and industrial uses operating in the business park, by allowing all uses within the Light Industrial (M1) zoning district. Subsequently, on January 21, 2020, the City Council approved additional entitlements affecting the business park, including ZOA No. 2019-01 (Ordinance No. NS-2983), to allow school uses by right.

Prior to the approval of ZOA No. 2019-01, school uses had been in operation at the business park. Specifically, Templo Calvario operated a preschool and kindergarten at 2609 West Fifth Street since the 1990s. In 2003, the Edward B. Cole Senior Academy occupied the site until it relocated to another Santa Ana location in 2010. From 2011 to 2015, Templo Calvario once again operated a school at this location. In 2015, Vista Heritage Charter School took over operations at the site. In 2019, Vista Heritage Charter School expanded their 6-8th grade operation located at 2609 W. Fifth Street to include kindergarten through 5th grades within two adjacent suites, pursuant to approval of ZOA No. 2019-01, which also allowed an increase in student enrollment and school operations.

Currently, Vista Heritage Charter School occupies approximately 66,000 square feet of building space and accommodates a maximum of 870 students, at 2601 through 2617 West Fifth Street.

Project Analysis
The proposed project aims to achieve two primary objectives. First, the zoning ordinance amendment is seeking to expand the boundaries of SD-82 and allow an Administrative Office use on Parcel 4, and an Outdoor Play Areas on Parcel 2, as an ancillary use to the Vista Heritage Charter School. Second, the amendment application intends to amend the zoning map by rezoning the subject property from M1 to SD-82. The following sections of this report provides analysis for the proposed action item and the basis for staff’s recommendation of approval for the project.

Zoning Ordinance Amendment
Pursuant to SAMC Section 41-593.1, the purpose and intent of a specific development (SD) designation is to provide a tailored and flexible zoning approach to address specific and exceptional circumstances associated with certain parcels, while protecting and promoting the public health, safety and general welfare of the City and its residents. These circumstances may include unique characteristics, historical significance, or specific community needs that deviate from the standard zoning regulations. Moreover, SD designations protect and enhance the value of properties by encouraging the use of good design principles and concepts; encouraging, securing and maintaining the orderly and harmonious appearance, attractiveness and aesthetic development; providing a method whereby specific development plans are based on the general plan; and by recognizing the interdependence of land values and aesthetics and providing a method to implement interdependence.

For this specific proposal, the applicant is proposing to amend the SD-82 document to allow Administrative Offices as a permitted use on Parcel 4 and Outdoor Play Areas on Parcel 2, ancillary to the existing school. In response to this application, staff is proposing that SD-82 be revised pursuant to Table 3 below:

Table 3: Permitted Uses and Operational Standards for SD-82

REQUIREMENT ISSUE AND PROPOSED AMENDMENT
STANDARDS:

Circulation and Parking
Management Plan
Issue:

School traffic may conflict with local traffic patterns and adjacent uses. In primarily industrial districts, like SD-82, the impacts could be particularly severe.

Proposed Amendment:

The school prepared a Circulation and Parking Management Plan (“Plan”) that was reviewed as part of the Development Project Review (DP) that was submitted in February of 2023. The Plan takes into account the parking, onsite circulation, drop off, and pick up. The Plan identifies how the school buses will pick-up and drop-off students within the front parking lot. The Plan is designed to accommodate the existing school population and to ensure that there is no vehicle queuing off-site or conflicts with the adjacent industrial buildings to the north and west of the site. Future modifications to the Plan may require a traffic analysis to demonstrate compliance. Lastly, at this time, the project does not propose an increase in student enrollment or additional square footage.

REQUIREMENT ISSUE AND PROPOSED AMENDMENT
Physical Education
Activity Area
Standards
Issue:

Noise resulting from physical education or after-school sports activities can impact adjacent residents or tenants.

Proposed Amendment:

Physical education activity areas shall be designed so that their use does not disturb the commercial or industrial uses during regular business hours and residential uses between the hours of 8 p.m. and 7 a.m. As proposed, the physical education activities will be relocated to a designated gated area located directly adjacent to the existing school. In addition, the school’s regular hours are Monday through Friday from 8:30 a.m. to 3:00 p.m. Outdoor activities will not take place outside of the school’s regular hours. Furthermore, the noise sources are typically intermittent and short in duration. Additionally, the impact of noise diminishes significantly with distance from its origin. The sensitive receptors (residential zones and land uses) are situated approximately 200 feet away. Therefore, the proposed Outdoor Play Area’s generated noise would not adversely affect these sensitive receptors.

Administrative Offices Issue:

The administrative office may increase parking demand and traffic generation of the entire site.

Proposed Amendment:

The proposed change of use is not expected to impact the parking demand on-site due to specific parking requirements. The administrative office requires three (3) parking spaces per 1,000 square feet; whereas, the autorepair businesses required five (5) parking spaces per 1,000 square feet.

Additionally, the administrative office will only be employing a total of ten (10) individuals and the total increase in trip generation during peak hours is not significant enough to trigger concerns.

Maximum Student
Enrollment
Issue:

Number of students can dictate the level of impact on adjacent uses. More students mean more cars or buses picking up or dropping off students, more children on the playground and more noise
Proposed Amendment:

The proposed number of students will not increase. The number of student enrollment will remain at a maximum of 870 students. This enrollment cap will remain in the SD document.

Industrial Uses Issue:

The current list of permitted uses in SD-82 contains various industrial uses, which are no longer consistent with the General Plan land use designation and the designated focus area. The Flex-1.5 land use designation encourages industrial uses that do not produce significant air pollutants including office-industrial flex spaces, small-scale clean manufacturing, research and development, among other uses. Moreover, the focus area is intended to transition a group of auto-oriented neighborhoods and City Council 26 – 298 1/16/2024

REQUIREMENT ISSUE AND PROPOSED AMENDMENT
institutions into a series of transit-oriented neighborhoods that support and benefit from future streetcar stops.

Proposed Amendment:

The proposed amendment will update the list of permissible uses per zone to establish consistency with the Flex-1.5 General Plan land use designation and the focus area.

Amendment Application
Currently, the site to the south of 601 N. Fairview Street is zoned SD-82, and the proposed rezoning intends to align the subject site with the existing development to the south.

Within the SD-82 regulations, permissible uses encompass industrial, school, and church uses. Expanding the SD-82 boundaries will accommodate additional administrative office use at 601 N. Fairview Street. This zoning adjustment aims to repurpose the existing industrial building, historically serving as an auto-repair business, into an administrative office space.

Under the current M1 zoning, only up to thirty percent of the gross floor area can be allocated for administrative office use. The proposed rezoning, coupled with amendments to the SD-82 regulations, seeks to enable the existing building's operation as an administrative office without constraint, limited to Parcel 4. More importantly, the rezoning is not anticipated to exacerbate traffic flow, parking demands, or noise impacts. As detailed in Table 3, the proposed rezoning is projected to address and mitigate any potential adverse effects on the surrounding community.

General Plan Consistency
The approval of the subject project will be consistent with the General Plan land use designation and the designated focus area. The subject site is located within the Industrial/Flex-Low (Flex-1.5) General Plan land use designation. The Flex-1.5 land use designation encourages a myriad of industrial uses that do not produce significant air pollutants including office-industrial flex spaces, small-scale clean manufacturing, research and development, among other uses. Furthermore, the site is located within one of the five focus areas as prescribed by the General Plan. Specifically, the site is located within the West Santa Ana Boulevard Focus Area. The focus area is intended to transition a group of auto-oriented neighborhoods and institutions into a series of transit-oriented neighborhoods that support and benefit from future streetcar stops. In order to accomplish the goals of the General Plan, the focus area promotes infill development while respecting established neighborhoods and providing buffers from industrial to residential neighborhoods. The proposed project will create a buffer from industrial uses to City Council 26 – 299 1/16/2024

residential by changing the use of an auto-repair building into an office space.

Additionally, the proposed project proposes landscape improvements and a community garden that will further act as buffers and accomplish the goals of the General Plan.

Moreover, the approval of the proposed applications will be consistent with the goals and policies of the General Plan, specifically Goals 1, 2, and 3 of the Land Use Element (LU).

Goal 1 of the LU provides a land use plan that improves the quality of life and respects the existing community. Policy 1-8 encourages new development to provide a new community benefit. The change of use from auto-repair to office will provide a benefit to the community by reducing the noise, fumes, and waste that stem from auto-repair-like businesses. Additionally, the outdoor play area for the school will allow the school to offer their students a space for recreational purposed within their business hours. Goal 2 of the LU seeks a balance of land uses to meet Santa Ana’s diverse needs. Policy 2-6 promote rehabilitation of properties and encourage increased levels of capital investment to create a safe and attractive environment. Approval of the amendment application and the zoning ordinance amendment will promote the rehabilitation of the existing building with a new façade and site improvements. Goal 3 of the LU seeks to preserve and improve the character and integrity of existing neighborhoods and districts. Policy 3-7 promotes a clean, safe, and creative environment for Santa Ana’s residential, workers and visitors.

Approval of the project will promote a clean, safe, and creative environment for Santa Ana’s residents by reducing hazardous waste produced by auto repair businesses, enhancing the architecture of the existing building, and enhancing the site by introducing new landscape.

Covenants, Conditions and Restrictions
During the development review phase of the project, the City obtained information concerning the Covenants, Conditions, and Restrictions (CC&Rs) governing both Parcel 2 and Parcel 4 illustrated in Exhibit 9. These CC&Rs outline potential use restrictions that could impact these parcels. However, these stipulations do not hinder the City's authority to proceed with the intended rezoning and revising of the SD-82 text. Furthermore, the text of SD-82 requires the update and clarification of these CC&Rs, mandating their refinement and subsequent submission to the City before permit issuance.

Public Notification and Community Outreach
Project notifications were posted, published, and mailed in accordance with City and State regulations. Copies of the public notice, including a 1,000-foot notification radius map, and the site posting are provided in Exhibit 5. There are no established Neighborhood Associations in the vicinity as the property is surrounded by offices and the City of Costa Mesa. At the time this report was printed, no issues of concern were raised regarding the proposed development.

In addition to the above noticing, the project was subject to the City’s Sunshine Ordinance (Ordinance No. NS-3040) requiring two meetings to facilitate early public participation.

The first community meeting was held March 6, 2023. Eleven members of the community attended and posted questions relating to on-site traffic circulation, the outdoor play area, the location of the proposed fences, and parking concerns. The second community meeting was held May 15, 2023, during which 10 members of the community attended and expressed that the site plan did not address the traffic circulation concerns raised previously. Materials from the two required community meetings are included with this report as Exhibit 8, and all materials were published to the project’s webpage on the City’s website at santa-ana.org/vista-charter-school/.

Additional Outreach
The applicant organized an additional meeting on May 23, 2023 with stakeholders, City staff, and Orange County Transportation Authority (OCTA) staff to discuss the parking requirements of Parcel 2 and Parcel 4 listed in the CC&Rs and optional overflow parking not listed in the CC&Rs for Templo Calvario. Moreover, on November 3 and November 15, the applicant met with various stakeholders to discuss the proposed site plan, parking requirements, and clarification on the CC&Rs limitations. The purpose of the meetings was to ensure ongoing communication about the steps and substance needed in order to revise the CC&Rs to reflect the current project, should the requested entitlements be approved.

ENVIRONMENTAL IMPACT
Pursuant to the California Environmental Quality Act (CEQA) and the CEQA Guidelines, the project is exempt from further review per Section 15301 Existing Facilities (Class 1 – Existing Facilities) of the CEQA Guidelines and per Section 15183 (Projects Consistent with a Community Plan, General Plan, or Zoning) of the CEQA Guidelines.

Class 1 exemption applies to the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use as determined by the lead agency. The subject project is proposing the change of use of an existing industrial building that was previously used for an auto repair business to be used for administrative office purposes.

Additionally, the project is exempt from further review per Section 15183 (Projects Consistent with a Community Plan, General Plan, or Zoning) of the CEQA Guidelines.

The environmental review contained in Exhibit 7 has been prepared, and peer reviewed by a qualified CEQA consultant hired by the City, to assess the potential for the proposed project to result in environmental effects and whether the proposed project qualified for an exemption under Section 15183 of the CEQA Guidelines. Moreover, the analysis City Council 26 – 301 1/16/2024
AA No. 2023-04 and ZOA No. 2023-03 for Vista Heritage Charter School at 601 North Fairview Street

evaluated whether the potential environmental impacts are addressed in the City of Santa Ana General Plan Update Final Recirculated Program Environmental Impact Report (GPU EIR). Specifically, the analysis evaluates the change of use of the existing 5,837- square-foot building from auto-repair to administrative office and site improvements that include new landscaping, façade remodel, and new outdoor areas for the office and the school.

CEQA Guidelines Section 15183 allows a streamlined environmental review process for projects that are consistent with the densities established by existing zoning, community plan, or general plan policies for which an EIR was certified and does not require additional environmental review, except as might be necessary to examine whether there are project-specific significant effects which are peculiar to the project or its site.

Moreover, projects that are consistent with the densities and use characteristics considered by the GPU EIR may qualify for the CEQA Guidelines Section 15183 Exemption process. This exemption process may be used when a project meets the following conditions:
a) The project is consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified. b) There are no project specific effects which are peculiar to the project or its site. c) There are no project specific impacts which the prior EIR failed to analyze as significant effects.
d) There are no potentially significant off-site and/or cumulative impacts which the prior EIR failed to evaluate.
e) There is no substantial new information which results in more severe impacts than anticipated by the prior EIR.

The GPU was adopted, and the GPU EIR certified, in April 2022 (State Clearinghouse Number 2020029087); the GPU went into effect on May 26, 2022. Any decision by the City affecting land use and development must be consistent with the GPU. The GPU EIR evaluates the potential environmental effects associated with implementation of the GPU and addresses appropriate and feasible mitigation measures that would minimize or eliminate these impacts. Pursuant to Section 15183(i)(2) of the CEQA Guidelines, a project is consistent with the GPU if the development density does not exceed what was contemplated and analyzed for the parcel(s) in the certified GPU EIR and complies with the associated standards applicable to that development density. Development density standards can include the number of dwelling units per acre, the number of people in a given area, floor area ratio (FAR), and other measures of building intensity, building height, size limitations, and use restrictions.

The GPU identifies that the Interim Development Standard for the FLEX-1.5 area are those development standards outlined for the M1 zoning designation. The M1 zone provides for a variety of light industrial uses, including warehousing, manufacture, City Council 26 – 302 1/16/2024
AA No. 2023-04 and ZOA No. 2023-03 for Vista Heritage Charter School at 601 North Fairview Street

Page 11 ends

assembly, machine shops, wholesale businesses and ancillary uses such as office uses that do not exceed thirty (30) percent of the gross floor area. The Project would result in a FAR of 0.14, which is within the projections of the GPU EIR, which evaluated a density of 1.5 FAR on the site. The GPU EIR adequately anticipated and analyzed the impacts of this Project, identified applicable mitigation measures necessary to reduce impacts of the Project, and the Project implements the applicable mitigation measures. The Project, therefore, qualifies for an exemption from additional environmental review as set forth in State CEQA Guidelines Section 15183. The full exemption analysis is provided as Exhibit 7 of this report. Based on this analysis, a Notice of Exemption, Environmental Review No. 2023-40 will be filed for this project.

ECONOMIC AND FISCAL IMPACTS
To date, the proposed project has generated a total of 156 temporary employment opportunities, including environmental engineers, environmental remediation technicians, demolition crew, architects, engineers, development consultants, and an attorney.

Additionally, the new administrative office will create ten permanent employment positions. Moreover, the applicant will pay approximately $46,235 in entitlement, plan check, and permit fees.

There is no fiscal impact associated with this action.

ORDINANCE NO. NS-XXXX

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF

SANTA ANA APPROVING AMENDMENT APPLICATION
NO. 2023-04 AMENDING THE ZONING FOR THE
PROPERTY LOCATED AT 601 NORTH FAIRVIEW STREET
(APN: 405-241-04) FROM LIGHT INDUSTRIAL (M1) TO
SPECIFIC DEVELOPMENT NO. 82 (SD-82)

THE CITY COUNCIL OF THE CITY OF SANTA ANA HEREBY ORDAINS AS FOLLOWS:

Section 1. The City Council of the City of Santa Ana hereby finds, determines and declares as follows:

A. Red Hook Capital Partners, LLC with Vista Heritage Charter Schools (“Applicant”) representing 2609 W. 5th Street LLC (Property Owner) is requesting approval of Amendment Application (AA) No. 2023-04 to change the zoning designation of the property located at 601 North Fairview Street (APN: 405-241-04) from Light Industrial (M1) to Specific Development No. 82 (SD-82) in order to facilitate the change of use of an existing auto-repair business to an administrative office.

B. Chapter 41, Article I, Division 1, Section 41-1 of the Santa Ana Municipal Code establishes that because of the necessity of segregating the location of residences, businesses, trades and industries; regulating the use of buildings, structures, and land; and regulating the location, height, bulk and size of buildings and structures, the size of yards and open spaces, the City is divided into land-use districts of such number, shape and area as may be considered best suited to carry out these regulations and provide for their enforcement. The regulations are considered necessary in order to:
encourage the most appropriate use of land, conserve and stabilize property value, provide adequate open spaces for light and air and to prevent and fight fires, prevent undue concentration of population, lessen congestion on streets and highways, and promote the health, safety and general welfare of the people, all as part of the general plan of the City. The City of Santa Ana has adopted a zoning map which has since been amended from time to time.

C. On April 19, 2022, the City adopted the General Plan Update and it went into effect on May 26, 2022. The approval of the subject project is consistent with the Industrial/Flex-Low (Flex-1.5) General Plan land use designation and the designated West Santa Ana Boulevard Focus Area. The Flex-1.5 land use designation encourage a myriad of industrial uses that do not produce significant air pollutants including office-industrial flex spaces, small-scale clean manufacturing, among other uses. Furthermore, the focus area is intended to transition a group of auto-oriented neighborhoods and City Council 26 – 304 1/16/2024
Ordinance No. NS-XXXX

Page 2 of 6 ends

institutions into a series of transit-oriented neighborhoods that support and benefit from future streetcar stops. In order to accomplish the goals of the General Plan, the focus area promotes infill development while respecting established neighborhoods and providing buffers from industrial to residential neighborhoods. The proposed project will create a buffer from industrial uses to residential by changing the use of an auto-repair building into an office space. Additionally, the proposed project proposes landscape improvements and a community garden that will further act as buffers and accomplish the goals of the General Plan.

D. The entire Project as currently proposed entails, among other things, (1) Approval of Amendment Application No. 2023-07 to change the site’s zoning designation from Light Industrial (M1) to Specific Development No. 82 (SD-82) and (2) approval of Zoning Ordinance Amendment No. 2023-03 to expand the boundaries of SD-82 and to allow for Administrative Offices as a permitted use on Parcel 4, and an Outdoor Play Area in Parcel 2 ancillary to the Vista Heritage Charter School.

E. The Applicant has demonstrated compliance with all requirements of the Sunshine Ordinance codified at Santa Ana Municipal Code Section 2-153, including public notification and hosting of required community meetings.

Materials resulting from the meetings were subsequently posted to the City’s webpage for the project.

F. On December 11, 2023, the Planning Commission held a duly noticed public hearing and voted to recommend that the City Council adopt an ordinance approving Amendment Application No. 2023-04.

G. For the reasons contained herein, and each of them, Amendment Application No. 2023-04 is hereby found and determined to be consistent with the intent and purpose of Chapter 41 of the Santa Ana Municipal Code; thus, changing the zoning district is found to be consistent with the General Plan of the City of Santa Ana and otherwise justified by the public necessity, convenience, and general welfare.

Section 2. The Amendment Application consists of amendments to the Zoning Map, as shown in Exhibit A, attached hereto and incorporated herein by reference.

Section 3. The City Council has reviewed and considered the information contained in the analysis performed pursuant to the California Environmental Quality Act (CEQA) (Environmental Review No. 2023-40). In accordance with the California Environmental Quality Act (CEQA) and the CEQA Guidelines, the project is categorically exempt from further review per Section 15301 (Class 1 – Existing Facilities) of the CEQA Guidelines. Class 1 exemption applies to the operation, repair maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use. The subject project is proposing the change of use of an existing industrial building that was previously used for an auto repair business to be used for administrative office purposes. Additionally, the project is exempt from further review City Council 26 – 305 1/16/2024
Ordinance No. NS-XXXX

Page 3 of 6 ends

pursuant to Public Resources Code section 21083.3 and CEQA Guidelines Section 15183, the Project is exempt from further review. This type of exemption analysis evaluates whether the potential environmental impacts of the proposed change of use for the existing 5,837-square-foot building from auto-repair to administrative office and site improvements that include new landscape, façade remodel, and new outdoor areas for the office and the school are addressed in the City of Santa Ana General Plan Update Final Recirculated Program Environmental Impact Report (GPU EIR). A rezoning that is consistent with an adopted general plan falls within this exemption. (A) As set forth in CEQA Guidelines Section 15183(a), projects that are “consistent with the development density established by the existing zoning, community plan or general plan policies for which an EIR was certified shall not require additional environmental review, except as might be necessary to examine whether there are project-specific significant effects which are peculiar to the project or its site.” The CEQA Guidelines further state that “[i]f an impact is not peculiar to the parcel or to the project, has been addressed as a significant effect in the prior EIR, or can be substantially mitigated by the imposition of uniformly applied development policies or standards . . . then an additional EIR need not be prepared for the project solely on the basis of that impact.” CEQA Guidelines Section 15183(c).
(B) The GPU was adopted, and the GPU EIR certified, in April 2022 (State Clearinghouse Number 2020029087); the GPU went into effect on May 26, 2022. Any decision by the City affecting land use and development must be consistent with the GPU.

The GPU EIR evaluates the potential environmental effects associated with implementation of the GPU and addresses appropriate and feasible mitigation measures that would minimize or eliminate these impacts. A project is consistent with the GPU if its development density is the same or less than the standard expressed for the involved parcel in the general plan for which an EIR has been certified, and the project complies with the density-related standards contained in that plan. CEQA Guidelines section 15183(i)(2). Development density standards can include the number of dwelling units per acre, the number of people in a given area, floor area ratio (FAR), and other measures of building intensity, building height, size limitations, and use restrictions. (C) The GPU identifies that the Interim Development Standard for the FLEX-1.5 area is M1. The M1 zone provides for a variety of light industrial uses, including warehousing, manufacture, assembly, machine shops, wholesale businesses and ancillary uses such as office uses that do not exceed thirty (30) percent of the gross floor area. The Project would result in a FAR of 0.14, which is within the projections of the GPU EIR, which evaluated a density of 1.5 FAR on the site. The GPU EIR adequately anticipated and analyzed the impacts of this Project and identified applicable mitigation measures necessary to reduce impacts of the Project, and the Project implements the applicable mitigation measures.
(D) Specifically, the Project qualifies for the exemption because the following findings can be made:

1. The Project is consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified.

City Council 26 – 306 1/16/2024
Ordinance No. NS-XXXX

Page 4 of 6 ends

The Project would result in a FAR of 0.14, which is less than the maximum FAR of

1.5 allowable in the FLEX-1.5 designated area, which is the development density established by the GPU and analyzed in the GPU EIR. The Project site has an Interim Development Standard of M-1 (light Industrial zone). The M-1 zone does not have density requirements.

2. There are no Project specific effects which are peculiar to the Project or its site, and which the GPU EIR failed to analyze as significant effects. The subject property is similar to other properties in the area, including its land use designation and zoning. The property does not support any peculiar environmental features, and the Project would not result in any peculiar effects. In addition, as explained further in the prepared Exemption Checklist, project impacts were adequately analyzed by the GPU EIR; and as detailed in the GPU EIR, development projects pursuant to the GPU, such as the proposed Project, could result in potentially significant impacts to air quality, greenhouse gas emissions, and noise. However, applicable mitigation measures specified within the GPU EIR would reduce potential impacts to a less than significant level.

3. There are no potentially significant off-site and/or cumulative impacts which the GPU EIR failed to evaluate. The Project is consistent with the density and use characteristics of the development considered by the GPU EIR and would represent a small part of the growth that was forecast for build-out of the GPU. The GPU EIR considered the incremental impacts of the Project, and as explained further in the prepared Exemption Checklist, no potentially significant off-site or cumulative impacts have been identified which were not previously evaluated.

4. There is no substantial new information which results in more severe impacts than anticipated by the GPU EIR. As explained in the prepared Exemption Checklist, no new information has been identified which would result in a determination of a more severe impact than what had been anticipated by the GPU EIR.

5. As explained in the prepared Exemption Checklist, the Project will undertake feasible mitigation measures specified in the GPU EIR. These GPU EIR mitigation measures will be undertaken through Project design, compliance with regulations and ordinances, and through the Project’s conditions of approval. (E) The Project therefore qualifies for an exemption from additional environmental review as set forth in Public Resources Code section 21083.3 and CEQA Guidelines Section 15183. The full exemption analysis is provided as Exhibit 7 of the staff report accompanying this Ordinance. Based on this analysis, a Notice of Exemption, Environmental Review No. 2023-40 will be filed for this project.

Section 4. An amended Sectional District Map, showing the above described changes in use district designation, is hereby approved and attached hereto as Exhibit A, and incorporated by this reference as though fully set forth herein.

Section 5. The City Council of the City of Santa Ana, after conducting the public hearing, hereby approves Amendment Application No. 2023-04. This decision is City Council 26 – 307 1/16/2024

If any section, subsection, sentence, clause, phrase or portion of this ordinance is for any reason held to be invalid or unconstitutional by the decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this ordinance. The City Council of the City of Santa Ana hereby declares that it would have adopted this ordinance and each section, subsection, sentence, clause, phrase or portion thereof irrespective of the fact that any one or more sections, subsections, sentences, clauses, phrases, or portions be declared invalid or unconstitutional.

THE CITY COUNCIL OF THE CITY OF SANTA ANA HEREBY ORDAINS AS FOLLOWS:

Section 1. The City Council of the City of Santa Ana hereby finds, determines and declares as follows:

A. On October 20, 2008, the City Council adopted Ordinance No. NS-2777, rezoning the property located at 2501 West Fifth Street, described as Parcels 1 and 2 of Parcel Map No. 84-886, as shown on a map filed in Book 198, Pages 19-20 of Parcels Maps in the Office of the County Recorder of Orange County, California, from Light Industrial (M-1) to Specific Development Plan No. 82 (SD-82).

B. On January 21, 2020, the City Council adopted Ordinance No. NS-2983, to amend the Santa Ana Municipal Code (SAMC) to include a definition of “schools”; allow schools as a permitted use in SD-82; to adopt a set of operational standards for schools within SD-82; allow Vista Heritage Charter School to expand to 66,000 square feet in size; and allow Vista Heritage Charter School to expand the student enrollment to 870 students.

C. The proposed Project would only affect Parcel 1, 2, and 4, of Parcel Map No. 84-886, as shown on a Map filed in Book 198, Pages 19-20 of Parcel Maps in the Office of the County Recorder of Orange County, California.

D. The proposed Project entails, among other things, (1) Approval of Amendment Application No. 2023-04 to change the zoning designation for the property located at 601 North Fairview Street (APN: 405-241-04) from Light Industrial (M1) to Specific Development No. 82 (SD-82); and (2) approval of Zoning Ordinance Amendment No. 2023-03 to expand the boundaries of SD-82 and to allow for Administrative Offices, Surface Parking, and Private Outdoor Community Areas as a permitted use on Parcel 4, and Outdoor Play Area on Parcel 2, ancillary to the Vista Heritage Charter School. Parcel 2 and 4 are as shown on Parcel Map No. 84-886, as City Council 26 – 311 1/16/2024

shown on a Map filed in Book 198, Pages 19-20 of Parcel Maps in the Office of the County Recorder of Orange County, California.

E. The approval of the text amendments, permissible uses, and development standards are consistent with the General Plan land use designation of Industrial/Flex-1.5 (Flex 1.5) and the designated West Santa Ana Boulevard Focus Area. On April 19, 2022, the City adopted the General Plan Update which went into effect on May 26, 2022. The Flex-1.5 land use designation encourages industrial uses that do not produce significant air pollutants including office-industrial flex spaces, small-scale clean manufacturing, among other uses. Furthermore, the focus area is intended to transition a group of auto-oriented neighborhoods and institutions into a series of transit-oriented neighborhoods that support and benefit from future streetcar stops. In order to accomplish the goals of the General Plan, the focus area promotes infill development while respecting established neighborhoods and providing buffers from industrial to residential neighborhoods. The proposed project will create a buffer from industrial uses to residential by changing the use of an auto-repair building into an office space. Additionally, the proposed project proposes landscape improvements and a community garden that will further act as buffers and accomplish the goals of the General Plan.

F. The applicant has demonstrated compliance with all requirements of the Sunshine Ordinance codified at SAMC Section 2-153, including public notification and hosting of required community meetings. Materials resulting from the meetings were subsequently posted to the City’s webpage for the project.

G. On December 11, 2023, the Planning Commission held a duly noticed public hearing and voted to recommend that the City Council adopt an ordinance approving Zoning Ordinance Amendment No. 2023-03.

H. For the reasons contained herein, and each of them, Zoning Ordinance Amendment No. 2023-3 is hereby found and determined to be consistent with the intent and purpose of Chapter 41 of the SAMC; thus, changing the zoning district is found to be consistent with the General Plan of the City of Santa Ana and otherwise justified by the public necessity, convenience, and general welfare.

Section 2. The recitals above are each incorporated by reference and adopted as findings by the City Council.

leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use. The subject project is proposing the change of use of an existing industrial building that was previously used for an auto repair business to be used for administrative office purposes. Additionally, the project is exempt from further review pursuant to Public Resources Code section 21083.3 and CEQA Guidelines Section 15183, the Project is exempt from further review. This type of exemption analysis evaluates whether the potential environmental impacts of the proposed change of use for the existing 5,837-square-foot building from auto-repair to administrative office and site improvements that include new landscape, façade remodel, and new outdoor areas for the office and the school are addressed in the City of Santa Ana General Plan Update Final Recirculated Program Environmental Impact Report (GPU EIR). A rezoning that is consistent with an adopted general plan falls within this exemption. (A) As set forth in CEQA Guidelines Section 15183(a), projects that are “consistent with the development density established by the existing zoning, community plan or general plan policies for which an EIR was certified shall not require additional environmental review, except as might be necessary to examine whether there are project-specific significant effects which are peculiar to the project or its site.” The CEQA Guidelines further state that “[i]f an impact is not peculiar to the parcel or to the project, has been addressed as a significant effect in the prior EIR, or can be substantially mitigated by the imposition of uniformly applied development policies or standards . . . then an additional EIR need not be prepared for the project solely on the basis of that impact.” CEQA Guidelines Section 15183(c).
(B) The GPU was adopted, and the GPU EIR certified, in April 2022 (State Clearinghouse Number 2020029087); the GPU went into effect on May 26, 2022. Any decision by the City affecting land use and development must be consistent with the GPU.

(D) Specifically, the Project qualifies for the exemption because the following findings can be made:

1. The Project is consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified.

The Project would result in a FAR of 0.14, which is less than the maximum FAR of

CEQA Exemption 15183 – Environmental Documentation
Date: December 5, 2023
Project: Vista Charter Public Schools District Office and Outdoor Space Project To: City of Santa Ana
CC: Vince Fregoso, Vista Charter Public Schools
Ingrid Canedo, Vista Charter Public Schools
From: Frances Yau, AICP, Michael Baker International
Alan Ashimine, Michael Baker International
The City of Santa Ana (City) has received a project application for the proposed Vista Charter Public Schools District Office and Outdoor Space Project (project), located at 601 and 615 North Fairview Street, Santa Ana, Orange County, California (Assessor’s Parcel Numbers [APN] 405- 241-04). As documented herein, the proposed project meets the conditions for a statutory exemption pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15183 (California Public Resources Code 21083.3) to allow for a streamlined environmental review process.

1. Project Background
On April 19, 2022, the Santa Ana City Council adopted the Golden City Beyond (General Plan Update) and certified the Santa Ana General Plan Update Final Recirculated Program Environmental Impact Report (GPU EIR), dated October 2021. The General Plan Update provides long-term policy direction to guide the physical development, quality of life, economic health, and sustainability of the City through 2045. The General Plan Update consists of the following 12 elements: Community, Economic Prosperity, Mobility, Public Services, Conservation, Noise, Open Space, Safety, Land Use, Historic Preservation, Housing, and Urban Design. According to the GPU EIR, the full buildout of the General Plan Update (year 2045) would result in a net increase of 96,855 person, 36,261 housing units, 5,849,220 nonresidential square footage, and 11,436 jobs as compared to existing conditions in 2019.

The GPU EIR was prepared pursuant to Section 15168 of the CEQA Guidelines and allows analysis consistent with the high-level nature of the General Plan Update. The programmatic environmental document may be used to eliminate or reduce the scope of future environmental review for individual projects that are consistent with the General Plan Update pursuant to CEQA Guidelines Section 21083.3 and other streamlining provisions authorized by CEQA. Later projects implemented after the General Plan Update are examined with consideration of the GPU EIR to determine whether subsequent environmental analysis or documentation must be prepared. In addition, the CEQA Guidelines currently provide for streamlining through Section 15183, Projects Consistent with a Community Plan or Zoning, Section 15183.3, Streamlining for Infill Projects, and 15183.5, Tiering and Streamlining the Analysis of Greenhouse Gas Emissions.

CEQA Guidelines Section 15183 allows a streamlined environmental review process for projects that are consistent with the densities established by existing zoning, community plan, or general plan policies for which an EIR was certified. Specifically, as set forth in CEQA Guidelines Section 15183(d), the 15183 exemption applies to projects which meet the following conditions:

Exhibit 7 - Environmental Analysis and Exemption
City Council 26 – 350 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 2
(1) The project is consistent with:
(A) A community plan adopted as part of a general plan, (B) A zoning action which zoned or designated the parcel on which the project would be located to accommodate a particular density of development, or (C) A general plan of a local agency, and
(2) An EIR was certified by the lead agency for the zoning action, the community plan, or the general plan.

Further, as set forth in CEQA Guidelines Section 15183(e), the 15183 exemption applies when all feasible mitigation measures identified in the applicable general plan are implemented by the public agency with jurisdiction to require such mitigation measures.

As demonstrated throughout this memorandum, the project would qualify for streamlining of environmental review as a project consistent with a community plan or zoning under CEQA Guidelines Section 15183.

2. Project Description

2.1 Project Location
The City is located in central Orange County, generally north of the San Diego Freeway (Interstate 405 [I-405]), south of the Garden Grove Freeway (State Route 22 [SR-22]), and west of the Costa Mesa Freeway (SR-55) and Interstate 5 (I-5). The City is approximately 30 miles southeast of downtown Los Angeles; refer to Exhibit 1, Regional Vicinity. Santa Ana is surrounded by the cities of Orange and Garden Grove to the north, Tustin to the east, Costa Mesa and Irvine to the south, and Fountain Valley and Westminster to the west. The generally north-south trending Santa Ana River traverses the western portion of the City.

The approximately 0.9-acre project site is located at 601 and 615 North Fairview Street within the western portion of Santa Ana; refer to Exhibit 2, Site Vicinity. Regional access to the project site is provided via SR-22 and I-5. Local access to the site is provided via North Fairview Street and West 5th Street.

2.2 Existing Conditions
The project site is located within the Fairview Business Park, a highly developed and urbanized area of Santa Ana. The Fairview Business Park is occupied by institutional uses (i.e., Vista Heritage Global Academy and Templo Calvario Church) as well as various commercial and office uses (i.e., Echo Entertainment Inc., Small Wonders Children Center, IPW Industries Inc, A-1 Automotive Core Supplier, La Perla Spice Co., Inc., and Thai Eats).

As shown on Exhibit 2, the northern portion of the site consists of one existing approximately 5,837-square foot vacant building formerly occupied by auto repair businesses and associated surface parking along North Fairview Street. The southern portion of the site consists of a surface parking lot shared between Vista Heritage Global Academy and Templo Calvario Church. Minimal landscaping is present on-site; no trees are present within the project boundaries. The site is accessible from North Fairview Street via two driveways to the west, and two alleys connecting to West 5th Street to the south and southeast.

2.3 General Plan Designation and Zoning
According to the General Plan Update Land Use Element Figure LU-1, Land Use Map, the project site is designated Industrial/Flex-Low (FLEX-1.5).1 The Industrial/Flex designation is intended to provide context-appropriate development in areas with existing industrial uses. This land use designation allows for clean industrial uses that do not produce significant air pollutants, noise, or other nuisances typically associated with industrial uses, including office-industrial flex spaces, small-scale clean manufacturing, research and development and multilevel corporate offices, commercial retail, artist galleries, craft maker spaces, and live-work units. Adaptive reuse of buildings to accommodate live-work units is encouraged. Standalone residential is not permitted.

According to the General Plan Update Land Use Element Table LU-3, Density and Intensity Standards, the FLEX-1.5 designation allows a maximum 1.5 floor-area-ratio (FAR) and/or 30 dwelling per acre, with a maximum building height of three stories.

Based on the City of Santa Ana Zoning Map (Zoning Map), the site is zoned Light Industrial (M1) and Specific Development No. 82 (SD-82).2 According to Ordinance No. NS-2777, permitted uses in the SD-82 District are the uses permitted in the M1 zone as specified in Municipal Code Chapter 41, Article III, Division 18, M1 (Light Industrial) and schools by right and churches with a conditional use permit. Further, it is noted that the operational and development standards for the permitted and conditionally permitted Light Industrial Uses within the SD-82 zone shall be consistent with the operational and development standards found in Municipal Code Chapter 41, Article III, Division 18.

2.4 Project Characteristics
The project proposes to remodel and reoccupy a building formerly occupied by an automotive repair use as an office building for Vista Charter Public Schools. Specifically, the existing 5,837- square foot building would be remodeled for use as Vista Charter Public Schools district office; refer to Exhibit 3, Conceptual Site Plan. The existing open floor plan would be redesigned to include offices and conference rooms, with the exterior enhanced with new materials and color palette. The remodeled building would have approximately 5,764 square feet of usable interior space. Approximately 10 existing administrative staff would relocate from other Vista Charter educational facilities to the proposed district office; the project would not result in any new jobs.

The project would also redevelop the shared surface parking lot in the southern portion of the site into an outdoor area consisting of an approximately 2,297-square foot community garden, an approximately 7,372-square foot play field, and an approximately 4,640-square foot play yard; refer to Exhibit 3. Outdoor areas would serve administrative staff and existing students of the adjoining Vista Heritage Global Academy and would not increase existing school capacity. The community garden, play field, and play yard would not be for public use. 1 City of Santa Ana, Golden City Beyond, Santa Ana General Plan Land Use Element, Figure LU-1, Land Use Map, April 2022. 2 City of Santa Ana, City of Santa Ana Zoning Map, March 4, 2021.

Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 7
Ancillary improvements include landscaping, fencing along the perimeters of the proposed outdoor areas, and expansion of the existing parking lot. The front parking lot facing North Fairview Street would provide 20 parking spaces and the side parking lot adjacent to an existing railroad alignment (currently under construction for electric street cars) would provide 43 spaces.

In total, the site would provide 63 parking spaces.

Similar to existing conditions, the site is accessible from North Fairview Street via two driveways to the west, and two alleys connecting to West 5th Street to the south and southeast. Internal drive aisles would provide access to the proposed office building and outdoor areas. The student drop-off and pick-up area and internal circulation pattern would be slightly modified to accommodate the outdoor learning garden space and the outdoor play areas. Specifically, the fenced play yard would have a dual use. During drop-off and pick-up hours, the fence would be opened to allow for vehicles to use as a drop-off/pick-up turnaround area; no play yard activities would occur during these times. During school hours, the play yard fence would be closed for safety and students would be able to utilize the play yard for school activities.; refer to Exhibit 3.

2.4.1 Entitlements
To allow the use of the former automotive repair building for the proposed office use, a Zone Change would be required to modify the existing Light Industrial (M1) zoning for the site to Specific Development No. 82 (SD-82) to be consistent with the majority of the Fairview Business Park.

In addition to the proposed Zone Change, the project also proposes a Zoning Ordinance Amendment to amend the operational standards of the SD-82 zoning district to allow an outdoor play area. Under current SD-82 provisions, play areas for children are limited to indoors only.

2.4.2 Project Construction
Construction of the proposed project is anticipated to take approximately eight months to complete. The construction activities would include building construction, paving, and architectural coating. Construction activities would comply with the City’s Noise Ordinance, Section 18-314(e) of the Santa Ana Municipal Code (Municipal Code) and occur only Monday through Saturday between 7:00 a.m. and 8:00 p.m. Construction equipment and materials staging would occur within the project site. During construction, vehicular access would be provided via existing access points along North Fairview Street and/or West 5th Street.

3. California Environmental Quality Act Regulatory Setting CEQA applies to proposed projects initiated by, funded by, or requiring discretionary approvals from State or local government agencies. CEQA Guidelines apply generally to discretionary actions by agencies which may have a significant effect on the environment. However, where it can be seen with certainty that there is no possibility that an activity may have a significant effect on the environment, and if the activity meets the conditions for a CEQA Exemption, it is considered exempt from the provisions of CEQA. CEQA Guidelines Section 15183 allows a streamlined environmental review process for projects that are consistent with the densities established by existing zoning, community plan, or general plan policies for which an EIR was certified and does not require additional environmental review, except as might be necessary to examine whether there are project-specific significant effects which are peculiar to the project or its site.

Projects that are consistent with the densities and use characteristics considered by the GPU EIR may qualify for the CEQA Guidelines Section 15183 Exemption process. This exemption process may be used when a project meets the following conditions:

City Council 26 – 356 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 8
a) The project is consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified. b) There are no project specific effects which are peculiar to the project or its site. c) There are no project specific impacts which the prior EIR failed to analyze as significant effects.
d) There are no potentially significant off-site and/or cumulative impacts which the prior EIR failed to evaluate.
e) There is no substantial new information which results in more severe impacts than anticipated by the prior EIR.

It is the intention of the City to pursue an exemption for the proposed project. The environmental review contained in Section 4 has been prepared to assess the potential for the proposed project to result in environmental effects and whether the proposed project qualifies for an exemption under CEQA Guidelines Section 15183. The previously certified GPU EIR serves as the primary environmental compliance document for the project, and the text, standards of conditions, and applicable mitigation measures are incorporated by reference. Per the CEQA Guidelines, the exemption does not need to be circulated for public review but can be included in the staff report prior to making a decision on the project.

4. Environmental Review
This section includes an assessment, by issue area, of the proposed project’s potential effects on the environment.

4.1 Aesthetics

4.1.1 GPU EIR Findings
The GPU EIR concluded that while buildout of the General Plan Update would result in greater density and intensity in the five focus areas, aesthetic impacts would be less than significant with implementation of GPU EIR Regulatory Requirements (RR) AE-1 through AE-3. RR AE-1 requires the City to enforce adherence with the California Building Code, including provisions of the Building Energy Efficiency Standards related to lighting. RR AE-2 requires the City to enforce development standards and other general provisions as detailed in the Zoning Code (Municipal Code Chapter 41, Zoning) to ensure consistency between the General Plan and proposed development projects. Last, RR AE-3 requires the City to enforce the development standards and guidelines of adopted specific plans. The GPU EIR also states that visual resources in the City include views from public places of the Santiago Creek along the northern portion of the City and the Santa Ana River along the western portion of the City. There are no State-designated scenic highways in Santa Ana.

4.1.2 Project Analysis
The project site is located along North Fairview Street and is currently developed with one existing building formerly occupied by automobile repair businesses and associated surface parking. Due to intervening topography and ornamental vegetation, the Santa Ana River and Santiago Creek are not visible from the project site. The proposed project would renovate a former automotive repair building as the Vista Charter Public Schools district office. Although the proposed project City Council 26 – 357 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 9
would require a Zone Change to modify the site’s M1 zoning to SD-82, it would make the site’s zoning consistent with the rest of the Fairview Business Park. Additionally, no change in density or building height is proposed. Thus, the proposed project would be consistent with the allowed development density for the site’s FLEX-1.5 land use designation established by the General Plan Update and would have similar or lesser significant impacts than those analyzed in the GPU EIR.

Furthermore, development would be required to comply with existing standards governing aesthetics for the SD-82 zone, which is consistent with the standards for M1 uses in Municipal Code Chapter 41, Article III, Division 18. Overall, the project would renovate an unused, vacant automobile repair building as a school district office and provide outdoor areas with a community garden and play areas. Thus, the project would improve the aesthetic character of the project site and complement the existing development in the Fairview Business Park. Therefore, the proposed project would not have a substantial adverse effect on a scenic vista, damage scenic resources within a State-designated scenic highway, or conflict with existing policies governing scenic quality. Moreover, to further reduce impacts associated with the proposed project, implementation of RR AE-1 would ensure compliance with the California Building Code, including provisions of the Building Energy Efficiency Standards related to lighting and adherence to applicable development standards in the Zoning Code.

Additionally, the proposed project would comply with existing outdoor lighting standards for nonresidential buildings in Municipal Code Section 8-211, Special commercial building provisions, which require lighting to be contained on-site. Proposed nighttime lighting on-site for the outdoor areas would be limited to security lighting (i.e., no field lights that could impact neighboring uses at night). Therefore, impacts related to nighttime lighting and glare would be less than significant.

4.1.3 Conclusion
As such, the project is consistent with the General Plan Update. With implementation of RR AE1 and AE-2 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe aesthetic impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR AE-1 The City shall enforce adherence with the California Building Code, including provisions of the Building Energy Efficiency Standards related to lighting.

RR AE-2 The City shall enforce development standards and other general provisions as detailed in the Zoning Code (Chapter 41 of the Municipal Code) to ensure consistency between the City’s General Plan and proposed development projects.

This includes compliance with the requirements of any ordinance adopting specific development plans.

4.2 Agriculture and Forestry Resources

4.2.1 GPU EIR Findings
Most of the City, including the project site, is urbanized, developed, and does not provide opportunities for agricultural or forestry use. As stated in the GPU EIR, the City is nearly built out and does not contain any significant agricultural resources or land designated or zoned for agricultural use.

City Council 26 – 358 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 10

4.2.2 Project Analysis
The project site is fully developed and consists of a building formerly utilized by automobile repair businesses and a surface parking area within the Fairview Business Park. The project does not involve any land use changes related to agriculture, forest land, or timberland production. The project site and surrounding area are not designated as Prime Farmland, Unique Farmland, or Farmland of Statewide Importance, and do not include lands that qualify as forest land or timberland.3 Additionally, there are no lands in the City under a Williamson Act contract.4 Therefore, no impact to agricultural and forestry resources would occur.

4.2.3 Conclusion
Overall, the project is consistent with the General Plan Update, and would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to agriculture and forestry resources than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.3 Air Quality

4.3.1 GPU EIR Findings
The GPU EIR determined that the General Plan Update is inconsistent with the Air Quality Management Plan (AQMP) because buildout under the General Plan Update would exceed the population estimates assumed for the AQMP and would cumulatively contribute to the nonattainment designations of the South Coast Air Basin (Basin). The GPU EIR included Mitigation Measure AQ-2, which would reduce criteria air pollutant emissions from operationalrelated activities to the extent feasible; however, due to the magnitude and scale of the land uses that would be developed, no mitigation measures are available that would reduce operation and construction impacts below South Coast Air Quality Management District (SCAQMD) thresholds.

Therefore, the GPU EIR determined that impacts related to AQMP consistency and air quality emissions would remain significant and unavoidable.

The GPU EIR also determined that construction activities associated with buildout of the GPU could generate short-term emissions that exceed the SCAQMD significance thresholds and cumulatively contribute to the nonattainment designations of the Basin. Implementation of Mitigation Measure AQ-1 would reduce criteria air pollutant emissions from construction-related activities to the extent feasible. However, the GPU EIR determined that construction time frames and equipment for site-specific development projects have a potential for multiple development projects to be constructed at one time, resulting in significant construction-related emissions.

Thus, impacts were determined to be significant and unavoidable. 3 California Department of Conservation, California Important Farmland Finder, https://maps.conservation.ca.gov/DLRP/CIFF/, accessed June 29, 2023. 4 California Department of Conservation, California Williamson Act Enrollment Finder, https://gis.conservation.ca.gov/portal/home/webmap/viewer.html?webmap=18f7488c0a9d4d299f5e9c33b312f312, accessed July 26, 2023.

December 2023 Page 11

4.3.2 Project Analysis
The following section evaluates the potential short- and long-term air quality impacts that would result from the construction and operation of the proposed project. The analysis is primarily based upon Attachment A, Air Quality/Greenhouse Gas/Energy Modeling Results.

CONSISTENCY WITH APPLICABLE AIR QUALITY PLAN
In order to reduce emissions in the Basin, the SCAQMD adopted the 2022 Air Quality Management Plan (2022 AQMP) which establishes a program of rules and regulations directed at reducing air pollutant emissions and achieving State and Federal air quality standards. The AQMP is a regional and multi-agency effort including the SCAQMD, California Air Resources Board (CARB), the Southern California Association of Governments (SCAG), and the U.S.

Environmental Protection Agency (EPA).

The 2022 AQMP pollutant control strategies are based on the latest scientific and technical information and planning assumptions, including the 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (2020-2045 RTP/SCS), updated emission inventory methodologies for various source categories, and SCAG’s latest growth forecasts. SCAG’s latest growth forecasts were defined in consultation with local governments and with reference to local general plans. The SCAQMD considers projects that are consistent with the AQMP, which is intended to bring the Basin into attainment for all criteria pollutants, to also have less than significant cumulative impacts.

Criteria for determining consistency with the AQMP are defined by the following indicators:

Criterion 1:

With respect to the first criterion, SCAQMD methodologies require that an air quality analysis for a project include forecasts of project emissions in relation to contributing to air quality violations and delay of attainment.
i) Would the project result in an increase in the frequency or severity of existing air quality violations?
Since the consistency criteria identified under the first criterion pertains to pollutant concentrations, rather than to total regional emissions, an analysis of the project’s pollutant emissions relative to localized pollutant concentrations is used as the basis for evaluating project consistency. As discussed below, localized concentrations of carbon monoxide (CO), nitrogen oxides (NOX), particulate matter less than 10 microns in diameter (PM10), and particulate matter less than 2.5 microns in diameter (PM2.5) would be less than significant during project construction and operations. Therefore, the proposed project would not result in an increase in the frequency or severity of existing air quality violations.5 5 Because reactive organic gases (ROGs) are not a criteria pollutant, there is no ambient standard or localized threshold for ROGs. Due to the role ROG plays in ozone formation, it is classified as a precursor pollutant and only a regional emissions threshold has been established.

City Council 26 – 360 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 12
ii) Would the project cause or contribute to new air quality violations? As discussed below, the proposed project would result in emissions that are below the SCAQMD thresholds. Therefore, the project would not have the potential to cause or affect a violation of the ambient air quality standards.
iii) Would the project delay timely attainment of air quality standards or the interim emissions reductions specified in the AQMP?
The proposed project would result in less than significant impacts regarding regional and localized concentrations during project construction and operations As such, the project would not delay the timely attainment of air quality standards or 2022 AQMP emissions reductions.

Criterion 2:

With respect to the second criterion for determining consistency with SCAQMD and SCAG air quality policies, it is important to recognize that air quality planning within the Basin focuses on attainment of ambient air quality standards at the earliest feasible date. Projections for achieving air quality goals are based on assumptions regarding population, housing, and growth trends.

Thus, the SCAQMD’s second criterion for determining project consistency focuses on whether the proposed project exceeds the assumptions utilized in preparing the forecasts presented in the 2022 AQMP. Determining whether a project exceeds the assumptions reflected in the 2022 AQMP involves the evaluation of the three criteria outlined below. The following discussion provides an analysis of each of these criteria.
i) Would the project be consistent with the population, housing, and employment growth projections utilized in the preparation of the AQMP?
Growth projections included in the 2022 AQMP form the basis for the projections of air pollutant emissions and are based on general plan land use designations and SCAG’s 2020-2045 RTP/SCS demographics forecasts. The population, housing, and employment forecasts within the 2020-2045 RTP/SCS are based on local general plans as well as input from local governments, such as the City. The SCAQMD has incorporated these same demographic growth forecasts for various socioeconomic categories (e.g., population, housing, employment) into the 2022 AQMP.

The project site is designated FLEX-1.5 and is zoned M1 and SD-82 zones. The FLEX1.5 designation allows for various office uses, a maximum FAR of 1.5 and a maximum building height of three stories. The proposed project would renovate an existing 5,837- square foot building as an office building for Vista Charter Public Schools. The building is located on a 0.9-acre (39,204 square-foot) site, thus providing an FAR of 0.15. The existing building height would remain the same at 19 feet and four inches. As such, the project would meet the design standards of the FLEX-1.5 designation.

Permitted uses in the SD-82 zone are the uses permitted in the M1 zone as specified in Municipal Code Chapter 41, Article III, Division 18, M1 (Light Industrial), and schools by right and churches with a conditional use permit. Further, it is noted that the operational and development standards for the permitted and conditionally permitted Light Industrial Uses within the SD-82 zone shall be consistent with the operational and development standards found in Municipal Code Chapter 41, Article III, Division 18. To allow the use of the former automotive repair building for the proposed office use, a Zone Change would City Council 26 – 361 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 13
be required to modify the existing M1 zone to SD-82 to be consistent with the majority of the Fairview Business Park. In addition to the proposed Zone Change, the project also proposes a Zoning Ordinance Amendment to amend the operational standards of the SD82 zoning district to allow outdoor play areas. The project would also redevelop the shared surface parking lot in the southern portion of the site into an outdoor area consisting of an approximately 2,297-square foot community garden, an approximately 7,372-square foot play field, and an approximately 4,640-square foot play yard. Under current SD-82 provisions, play areas for children are limited to indoors only. Upon approval of the above entitlements, the proposed project would be consistent with the requirements of the General Plan Update and project site’s zoning, and would not conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. Impacts would be less than significant.

The project proposes to remodel and reoccupy a building formerly occupied by an automotive repair use as an office building for Vista Charter Public Schools. As discussed in Section 4.14, Population and Housing, Vista Charter Public Schools operates six public charter schools in Los Angeles and Orange County and serves a total of 1,500 students.

The proposed project creates an opportunity to have a district office located next to the organization’s largest school, Vista Heritage Global Academy. However, it is anticipated that the project would not generate new employment opportunities within the existing organization. Additionally, proposed outdoor areas would serve existing students of the adjoining Vista Heritage Global Academy and would not increase existing school capacity.

As a result, the proposed project would not directly or indirectly result in substantial unplanned population growth in the area or displace substantial numbers of existing people or housing. Additionally, as the SCAQMD has incorporated these same projections into the 2022 AQMP, it can be concluded that the proposed project would be consistent with the projections included in the 2022 AQMP. A less than significant impact would occur in this regard.
ii) Would the project implement all feasible air quality mitigation measures? The proposed project would result in less than significant air quality impacts. Compliance with all feasible emission reduction rules and measures identified by the SCAQMD would be required as identified in RR AQ-2 and AQ-3 below. As such, the proposed project meets this 2022 AQMP consistency criterion.
iii) Would the project be consistent with the land use planning strategies set forth in the AQMP?
Land use planning strategies set forth in the 2022 AQMP are primarily based on the 2020- 2045 RTP/SCS. There is an existing bus stop located less than one mile to the west of the project site operated by Orange County Transportation Authority. Further, the project would provide bicycle parking and encourage alternate mode of transportation. Therefore, the project would be consistent with the actions and strategies of the 2020-2045 RTP/SCS As such, the proposed project meets this AQMP consistency criterion.

In conclusion, the determination of 2022 AQMP consistency is primarily concerned with the longterm influence of a project on air quality in the Basin. The proposed project would not result in a long-term impact on the region’s ability to meet State and Federal air quality standards. Further, the proposed project’s long-term influence on air quality in the Basin would also be consistent with the SCAQMD and SCAG’s goals and policies and is considered consistent with the 2022 AQMP.

CRITERIA AIR POLLUTANTS
Construction Impacts
The project proposes to remodel and reoccupy an existing building to use as an office building for Vista Charter Public Schools and is not expected to involve any major construction activities. The project would be constructed over approximately eight months. Earthwork would be balanced onsite and would not require soil import or export. Exhaust emission factors for typical dieselpowered heavy equipment are based on the California Emissions Estimator Model version 2022.1 (CalEEMod) program defaults. Variables factored into estimating the total construction emissions include the level of activity, length of construction period, number of pieces and types of equipment in use, site characteristics, weather conditions, number of construction personnel, and the amount of materials to be transported on- or off-site. The analysis of daily construction emissions has been prepared utilizing CalEEMod. Refer to Attachment A for the CalEEMod outputs and results. Fugitive dust emissions are associated with land clearing, ground excavation, cut-and-fill, and truck travel on unpaved roadways (including demolition as well as construction activities). Exhaust emissions from construction activities include emissions associated with the transport of machinery and supplies to and from the project site, employee commutes to the project site, emissions produced on-site as the equipment is used, and emissions from trucks transporting materials to/from the site. In addition to gaseous and particulate emissions, the application of asphalt and surface coatings creates ROG emissions, which are O3 precursors.

Table 1, Project-Generated Construction Emissions, presents the anticipated daily short-term construction emissions.

Notes:

1. Emissions were calculated using CalEEMod version 2022.1.

2. Modeling assumptions include compliance with SCAQMD Rule 403 which requires: properly maintain mobile and other construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles with tarps; water all haul roads twice daily; and limit speeds on unpaved roads to 15 miles per hour.

Construction Emissions Conclusion
With the implementation of RR AQ-2 and AQ-3, criteria pollutant emissions during construction of the proposed project would not exceed the SCAQMD significance thresholds; refer to Table 1.

Thus, total construction related air emissions would be less than significant.

Operational Impacts
Long-term operational air quality impacts consist of mobile source emissions generated from project-related traffic and emissions from stationary area and energy sources. It should be noted that emission reductions from the existing uses are not taken into account as they are currently vacant. Area source emissions include those generated by architectural coatings, consumer City Council 26 – 363 1/16/2024

products, and landscape maintenance equipment associated with the development of the proposed project. Energy source emissions would be generated as a result of electricity and natural gas usage associated with the proposed project. Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions. Emissions associated with each source are detailed in Table 2, Project-Generated Operational Emissions.

Notes:

1. Emissions were calculated using CalEEMod version 2022.1 and are based on 7,000 square feet building area as a conservative analysis.

2. The numbers may be slightly off due to rounding.

Source: Refer to Attachment A for assumptions used in this analysis.

As shown in Table 2, the total operational emissions for both summer and winter would not exceed established SCAQMD thresholds. Therefore, impacts in this regard would be less than significant.

Air Quality Health Impacts
Adverse health effects induced by criteria pollutant emissions are highly dependent on a multitude of interconnected variables (e.g., cumulative concentrations, local meteorology and atmospheric conditions, and the number and character of exposed individual [e.g., age, gender]). In particular, O3 precursors, VOCs, and NOX, affect air quality on a regional scale. Health effects related to O3 are therefore the product of emissions generated by numerous sources throughout a region.

Existing models have limited sensitivity to small changes in criteria pollutant concentrations, and, as such, translating project-generated criteria pollutants to specific health effects or additional days of nonattainment would produce meaningless results. In other words, the project’s less than significant increases in regional air pollution from criteria air pollutants would have nominal or negligible impacts on human health.

As noted in the Brief of Amicus Curiae by the SCAQMD (April 6, 2015) for Sierra Club vs. County of Fresno, the SCAQMD acknowledged it would be extremely difficult, if not impossible to quantify health impacts of criteria pollutants for various reasons including modeling limitations as well as where in the atmosphere air pollutants interact and form. Further, as noted in the Brief of Amicus Curiae by the San Joaquin Valley Air Pollution Control District (SJVAPCD) (April 13, 2015) for the Sierra Club vs. County of Fresno, SJVAPCD acknowledged that currently available modeling tools are not equipped to provide a meaningful analysis of the correlation between an individual development project’s air emissions and specific human health impacts.

City Council 26 – 364 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 16
The SCAQMD acknowledges that health effects quantification from O3, as an example, is correlated with the increases in ambient level of O3 in the air (concentration) that an individual person breathes. The SCAQMD’s Brief of Amicus Curiae for Sierra Club vs. County of Fresno states that it would take a large amount of additional emissions to cause a modeled increase in ambient O3 levels over the entire region. The SCAQMD states that based on their own modeling in the SCAQMD’s 2012 AQMP, a reduction of 432 tons (864,000 pounds) per day of NOX and a reduction of 187 tons (374,000 pounds) per day of VOCs would reduce O3 levels at highest monitored sites by only nine parts per billion. As such, the SCAQMD concludes that it is not currently possible to accurately quantify O3-related health impacts caused by NOX or VOC emissions from relatively small projects (defined as projects with regional scope) due to photochemistry and regional model limitations. Thus, as the project would not exceed SCAQMD thresholds for construction and operational air emissions, the project would have a less than significant impact for air quality health impacts.

LOCALIZED POLLUTANTS AND SENSITIVE RECEPTORS
Sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses. Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. The CARB has identified the following groups of individuals as those most likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis.

The closest sensitive receptor to the project site is the Vista Heritage Global Academy School adjacent to the south of the project site. The closest residential uses are located approximately 100 feet to the north of the project site and the existing Romero-Cruz Academy school is located approximately 100 feet to the west.

Localized Significance Thresholds
Localized Significance Thresholds (LSTs) were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement Initiative (I-4). The SCAQMD provided the Final Localized Significance Threshold Methodology (dated June 2003 [revised 2008]) for guidance.

The LST methodology assists lead agencies in analyzing localized air quality impacts. The SCAQMD provides the LST lookup tables for one-, two-, and five-acre projects emitting CO, NOX, PM2.5, and/or PM10. The LST methodology and associated mass rates are not designed to evaluate localized impacts from mobile sources traveling over the roadways. The project site is located within Source Receptor Area (SRA) 17, Central Orange County.

Construction LST
The SCAQMD guidance on applying CalEEMod to LSTs specifies the number of acres a particular piece of equipment would likely disturb per day.6 SCAQMD provides LST thresholds for one-, two, and five-acre site disturbance areas; SCAQMD does not provide LST thresholds for projects over five acres. The project proposes to remodel and reoccupy a building formerly occupied by an automotive repair use as an office building for Vista Charter Public Schools and would not involve any grading or major construction related activities and therefore, there would not be any 6 The number of acres represent the total acres traversed by grading equipment. In order to properly grade a piece of land, multiple passes with equipment may be required. The disturbance acreage is based on the equipment list and days of the grading phase according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8-hour workday.

City Council 26 – 365 1/16/2024

December 2023 Page 17
significant on-site localized construction emissions. As such the project’s localized construction emissions would not exceed the LSTs for SRA 17 and localized significance impacts from projectrelated construction would be less than significant.

Operational LST
According to SCAQMD LST methodology, LSTs would apply to operational activities if the project includes stationary sources or attracts mobile sources that may spend extended periods queuing and idling at the site (i.e., warehouse or transfer facilities). The proposed project does not include such uses. Thus, due to the lack of such emissions, no long-term LST analysis is needed.

Operational LST impacts would be less than significant in this regard.

Carbon Monoxide Hotspots
CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow.

Under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels (e.g., adversely affecting residents, school children, hospital patients, and the elderly).

The Basin is designated as an attainment/maintenance area for the Federal CO standards and an attainment area under State standards. There has been a decline in CO emissions even though vehicle miles traveled (VMT) on U.S. urban and rural roads have increased; estimated anthropogenic CO emissions have decreased 68 percent between 1990 and 2014. In 2014, mobile sources accounted for 82 percent of the nation’s total anthropogenic CO emissions.7 Three major control programs have contributed to the reduced per-vehicle CO emissions, including exhaust standards, cleaner burning fuels, and motor vehicle inspection/maintenance programs.

According to the SCAQMD CEQA Air Quality Handbook, a potential CO hotspot may occur at any location where the background CO concentration already exceeds 9.0 parts per million (ppm), which is the 8-hour California ambient air quality standard. The closest monitoring station to the project site that monitors CO concentration is Anaheim – 812 West Vermont Street, which is located approximately 4.5 miles north of the project site. The maximum CO concentration at Anaheim – 812 West Vermont Street station was measured at 1.976 ppm in 2022.8 Given that the background CO concentration does not currently exceed 9.0 ppm, a CO hotspot would not occur at the project site. Therefore, CO hotspot impacts would be less than significant in this regard.

Asbestos
Asbestos is a term used for several types of naturally occurring fibrous minerals that are a human health hazard when airborne. The most common type of asbestos is chrysotile, but other types such as tremolite and actinolite are also found in California. Asbestos is classified as a known human carcinogen by State, Federal, and international agencies and was identified as a toxic air contaminant by CARB in 1986.

Asbestos can be released from serpentinite and ultramafic rocks when the rock is broken or crushed. At the point of release, the asbestos fibers may become airborne, causing air quality and human health hazards. These rocks have been commonly used for unpaved gravel roads, 7 U.S. Environmental Protection Agency, Carbon Monoxide Emissions, https://cfpub.epa.gov/roe/indicator_pdf.cfm?i=10, accessed July 3, 2023. 8 California Air Resources Board, Air Quality and Meteorological Information, 4.3.3 https://www.arb.ca.gov/aqmis2/aqdselect.php?tab=specialrpt, accessed July 3, 2023.

City Council 26 – 366 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 18
landscaping, fill projects, and other improvement projects in some localities. Asbestos may be released to the atmosphere due to vehicular traffic on unpaved roads, during grading for development projects, and at quarry operations. All of these activities may have the effect of releasing potentially harmful asbestos into the air. Natural weathering and erosion processes can act on asbestos bearing rock and make it easier for asbestos fibers to become airborne if such rock is disturbed. According to the Department of Conservation Division of Mines and Geology, A General Location Guide for Ultramafic Rocks in California – Areas More Likely to Contain Naturally Occurring Asbestos Report, serpentinite and ultramafic rocks are not known to occur within the project area.9
It is possible that the existing on-site structure contains asbestos. According to SCAQMD Rule 1403 requirements, prior to the start of demolition activities, the existing structure shall be thoroughly surveyed for the presence of asbestos by a person that is certified by Cal/OSHA for asbestos surveys. Rule 1403 requires that the SCAQMD be notified a minimum of 10 days before any demolition activities begin with specific details of all asbestos to be removed, start and completion dates of demolition, work practices and engineering controls to be used to contain the asbestos emissions, estimates on the amount of asbestos to be removed, the name of the waste disposal site where the asbestos will be taken, and names and addresses of all contractors and transporters that will be involved in the asbestos removal process. Therefore, through adherence to the asbestos removal requirements, detailed in SCAQMD Rule 1403, a less than significant asbestos impact would occur during construction of the proposed project.

Health Risk Impacts of On-Site Sensitive Receptors
The project site is located adjacent to an existing railroad and light industrial uses. Therefore, the proposed on-site outdoor play area could be exposed to potential health impacts. It should be noted that according to several court decisions, CEQA analysis is not required to analyze impacts of the existing environment on a proposed project unless the project risks exacerbating existing environmental hazards. As such, the following discussion on the health risk impacts of on-site sensitive receptors is for informational purposes only.

The SCAQMD recommends that health risk assessments be conducted for substantial sources of diesel particulate emissions (e.g., truck idling and movements, ship hoteling at ports, and train idling) and has provided guidance for analyzing mobile source diesel emissions.10 Similarly, CARB requires a health risk assessment when siting new sensitive land uses within 1,000 feet of a major service and maintenance rail yard or within 1,000 feet of a distribution center that accommodates more than 100 trucks per day.11 It should be noted that emissions of diesel particulate matter from train idling occurs predominantly at railroad yards, train stations, and train stops. Most train idling emissions are concentrated at railroad yards, where switching engines and local yard service operations are performed. The proposed project is located next to a railroad and is not located in the vicinity of a railyard or a train station. The railroad is currently not operational and is being developed to build a fixed guideway system called the Orange County Streetcar (OC Streetcar). The proposed OC Streetcars would be electrically-powered and would not consume diesel and thus, would not generate diesel particulate matter. Furthermore, the light industrial uses located to the south of the project site are small warehouses that do not qualify as a distribution center, and only involve occasional delivery truck trips that are much less than 100 9 California Department of Conservation Division of Mines and Geology, A General Location Guide for Ultramafic Rocks in California – Areas More Likely to Contain Naturally Occurring Asbestos Report, August 2000, https://ww3.arb.ca.gov/toxics/asbestos/ofr_2000-019.pdf, accessed April 3, 2023. 10 South Coast Air Quality Management District, Health Risk Assessment Guidance for Analyzing Cancer Risks from Mobile Source Diesel Emissions, December 2002. 11 California Air Resources Board, Air Quality and Land Use Handbook: A Community Health Perspective, April 2005.

City Council 26 – 367 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 19
truck trips per day. Therefore, diesel particulate matter emissions generated by the light industrial uses to the south are nominal and would not cause significant health impacts to on-site sensitive receptors (i.e., proposed outdoor play area).

As such, on-site sensitive receptors would have less than significant health impacts from the future operations of the OC Streetcar and the existing operations of adjacent light industrial uses, and potential health risk from the future OC Streetcar and existing light industrial uses on on-site sensitive receptors was not quantified. A less than significant impact would occur in this regard.

OBJECTIONABLE ODORS
According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. The proposed project does not include any uses identified by the SCAQMD as being associated with odors.

Construction activities associated with the project may generate detectable odors from heavyduty equipment exhaust and architectural coatings. However, construction-related odors would be short-term in nature and cease upon project completion. In addition, the project would be required to comply with the California Code of Regulations, Title 13, Sections 2449(d)(3) and 2485, which minimize the idling time of construction equipment either by requiring equipment to be shut off when not in use or limiting idling time to no more than five minutes. Compliance with these existing regulations would further reduce the detectable odors from heavy-duty equipment exhaust. Project’s compliance with RR AQ-3 would ensure compliance with the SCAQMD Regulation XI, Rule 1113 – Architectural Coating, which would minimize odor impacts from ROG emissions during architectural coating. Any odor impacts to existing adjacent land uses would be short-term and negligible. As such, the project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. Impacts would be less than significant in this regard.

4.3.3 Conclusion
Overall, the project is consistent with the General Plan Update. With implementation of RR AQ-1 though AQ-3 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe air quality impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR AQ-1 (amended) New buildings are required to achieve the current California Building Energy Efficiency Standards (Title 24, Part 6) and California Green Building Standards Code (CALGreen) (Title 24, Part 11). The 202219 Building Energy Efficiency Standards became effective January 1, 20220. The Building and Energy Efficiency Standards and CALGreen are updated tri-annually with a goal to achieve net zero buildings energy for 2030.

RR AQ-2 Construction activities will be conducted in compliance with California Code of Regulations, Title 13, Section 2449, which requires that nonessential idling of construction equipment is restricted to five minutes or less.

City Council 26 – 368 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 20
RR AQ-3 Construction activities will be conducted in compliance with any applicable South Coast Air Quality Management District rules and regulations, including but not limited to:
• Rule 403, Fugitive Dust, for controlling fugitive dust and avoiding nuisance. • Rule 402, Nuisance, which states that a project shall not “discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.”
• Rule 1113, which limits the volatile organic compound content of architectural coatings.
• Rule 1466, Soil Disturbance. Projects that involve earth-moving activities of more than 50 cubic yards of soil with applicable toxic air contaminants are subject to this rule.

4.4 Biological Resources

4.4.1 GPU EIR Findings
According to the GPU EIR, the City is built out with primarily industrial, commercial, and residential uses. Wildlife habitats within the City are generally limited to open space/vacant parcels, the Santa Ana River, and the Santiago Creek. While no development or land use changes are proposed in the City’s open space areas, sensitive species may still be present in Santa Ana and vegetation removal for redevelopment in the City could adversely impact special status species and/or migratory birds. Thus, Mitigation Measure BIO-1 would require screening by a qualified biologist to determine if a site-specific biological resources report is required for projects that disturb vegetated land or major streams.

No land use changes are proposed on parcels identified with riparian habitat, sensitive natural communities, or wetlands. Additionally, the City is not within a Natural Community Conservation Plan/Habitat Conservation Plan (NCCP/HCP) area. Thus, the GPU EIR concluded that the General Plan Update would have no impact in those regards.

4.4.2 Project Analysis
The project site is located within the General Plan Update West Santa Ana Boulevard Focus Area, which includes 28 open space designated parcels and zero vacant parcels. The project site is urbanized and fully disturbed/developed. The proposed project would renovate a former automotive repair building as the Vista Charter Public Schools district office and redevelop existing surface parking lots into an outdoor community garden, outdoor play field, and outdoor play yard. The project site does not include any wildlife or riparian habitat, sensitive natural communities, or wildlife corridors. Although the project site contains limited ornamental vegetation, the site does not include attributes that would be capable of supporting special status or sensitive plant species, or native resident or migratory species. Additionally, project compliance with RR B-2 would ensure any potential direct or indirect impacts to common bird species comply with California Fish and Game Code Section 3503, which prohibits the take, possession, or needless destruction of any bird’s nest or eggs. Further, all proposed activities would occur within City Council 26 – 369 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 21
established urbanized areas and not include land uses or activities that would remove or impact any biological resources. No new or substantially more severe impacts would occur compared to the determination in the GPU EIR, and no new mitigation measures are required.

As stated, the City is not within an NCCP/HCP area. Therefore, the proposed project would not conflict with an NCCP/HCP or other approved local, regional, or State habitat conservation plan.

4.4.3 Conclusion
Overall, the project is consistent with the General Plan Update. With implementation of RR B-2 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe biological resource impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR B-2 Regulatory requirement for potential direct/indirect impacts to common and sensitive bird and raptor species will require compliance with the California Fish and Game Code Section 3503.

4.5 Cultural Resources

4.5.1 GPU EIR Findings
The GPU EIR concluded that future development under the General Plan Update could adversely impact the City’s numerous historical properties listed in national, State, and local registers.

However, impacts would be reduced to less than significant levels upon implementation of RR CUL-1 through CUL-6 and Mitigation Measures CUL-1 through CUL-7. Specifically, Mitigation Measure CUL-1 would require a historical resources assessment (HRA) for structures 45 years or older. Mitigation Measure CUL-2 would require the maximum use of the Secretary of the Interior’s Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing Historic Buildings to ensure that projects involving relocation, conversion, rehabilitation, or alteration of a historic resources would not impair any historical significance. In the event that impacts to historical resources cannot be avoided, Mitigation Measure CUL-3 would require the affected historical resources to be thoroughly documented before issuance of any permits and may also require additional public education efforts and/or memorialization of the historical resource. To reduce impacts to archaeological resources and prior to ground-disturbing activities, Mitigation Measure CUL-4 requires an Archaeological Resources Assessment be conducted under the supervision of a qualitied archaeologist. If potentially significant archaeological resources are identified and impacts cannot be avoided, Mitigation Measure CUL-5 requires a Phase II Testing and Evaluation investigation be performed by a qualified archaeologist. If the Archaeological Resources Assessment does not identify archaeological resources but indicates the project area to be highly sensitive for archeological resources, a qualified archaeologist and a Native American monitor culturally affiliated with the project area must monitor all ground-disturbing activities in the areas of high archaeological sensitivity. Pursuant to Mitigation Measure CUL-7, if the Archaeological Resources Assessment does not identify potentially significant archaeological resources but the site has moderate sensitivity for archaeological resources, a qualified archaeologist must be retained on-call. Overall, implementation of regulatory requirements and Mitigation Measures CUL-1 through CUL-7 would reduce impacts to less than significant levels.

City Council 26 – 370 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 22

4.5.2 Project Analysis
The project site is located within the western portion of the West Santa Ana Boulevard Focus Area and does not contain any historical resources as defined by CEQA Guidelines Section 15064.5(a). Thus, no impacts would occur with regards to historical resources.

Although the project would redevelop the shared surface parking lot in the southern portion of the site into an outdoor community garden, play field, and play yard, the proposed project would not require extensive excavation that could uncover previously undiscovered archaeological resources or disturb human remains. Typical excavation depth would be a maximum of four feet for the majority of the site with the deepest excavation of approximately eight feet for an underground infiltration chamber related to stormwater improvements. RR CUL-1 requires that if human remains are discovered within the project site, disturbance of the site must halt until the County coroner has investigated and recommended treatment and disposition of the remains. If the human remains are determined to be Native American in origin, the Native American Heritage Commission must be contacted. Upon implementation of RR CUL-1, impacts would be less than significant in these regards. No new or substantially more severe impacts would occur compared to the determinations of the GPU EIR, and no new mitigation measures are required.

4.5.3 Conclusion
As such, the project is consistent with the General Plan Update. With implementation of RR CUL1, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe cultural resource impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR CUL-1 California Health and Safety Code Section 7050.5 requires that if human remains are discovered within the proposed project site, disturbance of the site shall halt and remain halted until the coroner has investigated the circumstances, manner, and cause of any death, and the recommendations concerning the treatment and disposition of the human remains have been made to the person responsible for the excavation, or to his or her authorized representative. If the coroner determines that the remains are not subject to his or her authority and if the coroner recognizes or has reason to believe the human remains to be those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission.

4.6 Energy

4.6.1 GPU EIR Findings
The GPU EIR determined that implementation of the General Plan Update policies, in conjunction with regulatory requirements, would ensure that energy demand associated with growth under the General Plan Update would not be inefficient, wasteful, or unnecessary. Additionally, the General Plan Update would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency.

City Council 26 – 371 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 23

4.6.2 Project Analysis

ENERGY CONSUMPTION
Construction
During construction, the project would consume energy in two general forms: (1) the fuel energy consumed by construction vehicles and equipment; and (2) bound energy in construction materials, such as asphalt, steel, concrete, pipes, and manufactured or processed materials such as lumber and glass.

Fossil fuels used for construction vehicles and other energy-consuming equipment would be used during building construction, paving, and architectural coatings. Fuel energy consumed during construction would be temporary and would not represent a significant demand on energy resources. In addition, some incidental energy conservation would occur during construction through compliance with State and RR E-1 requirements that heavy-duty diesel equipment not in use for more than five minutes be turned off. Project construction equipment would also be required to comply with the latest U.S. Environmental Protection Agency (EPA) and CARB engine emissions standards. These emissions standards require highly efficient combustion systems that maximize fuel efficiency and reduce unnecessary fuel consumption. Due to increasing transportation costs and fuel prices, contractors and owners have a strong financial incentive to avoid wasteful, inefficient, and unnecessary consumption of energy during construction.

Substantial reductions in energy inputs for construction materials can be achieved by selecting green building materials composed of recycled materials that require less energy to produce than non-recycled materials.12 Compliance with RR E-2 and the integration of green building materials can help reduce environmental impacts associated with the extraction, transport, processing, fabrication, installation, reuse, recycling, and disposal of these building industry source materials.13 The project-related incremental increase in the use of energy bound in construction materials such as asphalt, steel, concrete, pipes and manufactured or processed materials (e.g., lumber and gas) would not substantially increase demand for energy compared to overall local and regional demand for construction materials. The project proposes to remodel and reoccupy an existing building to use as an office building for Vista Charter Public Schools and is not expected to involve any major construction activities or construction of new structures. As such, the project’s fuel consumption from off-road construction equipment use would be nominal and would not significantly increase fuel use in the County. Similarly, the project’s fuel consumption from on-road construction vehicle use would be nominal and would not significantly increase fuel use in the County. As such, construction would have a nominal effect on the local and regional energy supplies. It is noted that construction fuel use is temporary and would cease upon completion of construction activities. There are no unusual project characteristics that would necessitate the use of construction equipment that would be less energy efficient than at comparable construction sites in the region or State. Therefore, by complying with RR E-1 and E2, construction fuel consumption would not be any more inefficient, wasteful, or unnecessary than other similar development projects of this nature. As such, a less than significant impact would occur in this regard.

Operations
Transportation Energy Demand
Pursuant to the federal Energy Policy and Conservation Act of 1975, the National Highway Traffic and Safety Administration is responsible for establishing additional vehicle standards and for revising existing standards. Compliance with federal fuel economy standards is not determined for each individual vehicle model. Rather, compliance is determined based on each manufacturer’s average fuel economy for the portion of their vehicles produced for sale in the United States. According to the Vista Heritage Global Academy Expansion Trip Generation Assessment prepared by Urban Crossroads and dated July 24, 2023, the proposed project would generate 84 average daily trips without taking trip reductions from the existing uses as they are currently vacant. As such, with the 84 average daily trips, the project would have a nominal increase the County’s automotive fuel consumption. The project does not propose any unusual features that would result in excessive long-term operational fuel consumption.

The key drivers of transportation-related fuel consumption are commuting for work and many personal choices on when to drive to the site for various purposes. Those factors are outside of the scope of the design of the proposed project. However, the project would provide on-site bicycle parking and promote the use of alternate mode of transportation. Additionally, an Orange County Transportation Authority bus stop is located less than 0.1 miles to the west of the project site. As such, this project would encourage and support the use of alternative modes of transportation, thus reducing petroleum fuel consumption.

Therefore, fuel consumption associated with vehicle trips generated by the project would not be considered inefficient, wasteful, or unnecessary in comparison to other similar developments in the region. A less than significant impact would occur in this regard.

Building Energy Demand
Compliance with RR E-3 and E-4 would ensure project’s compliance with the most current version of the 2022 Title 24 Building Energy Efficiency Standards (commonly known as Title 24), which provide minimum efficiency standards related to various building features, including appliances, water and space heating and cooling equipment, building insulation and roofing, and lighting.

Additionally, the project would exceed the 2022 Title 24 standards. Compliance with the current 2022 Title 24 standards significantly reduces energy usage. As modeled in CalEEMod and detailed in Attachment A, the project would consume 124,742 kilowatt-hour of electricity and 177,425 kilo British thermal units of natural gas per year, which is nominal compared to regional energy consumption. It should be noted that as a conservative analysis, existing uses on-site were not modeled or deducted from project energy consumption.

Furthermore, the electricity provider, SCE, is subject to California’s Renewables Portfolio Standard (RPS). The RPS requires investor-owned utilities, electric service providers, and community choice aggregators to increase procurement from eligible renewable energy resources to 60 percent of total procurement by 2030, and 100 percent by 2045. Renewable energy is generally defined as energy that comes from resources which are naturally replenished within a human timescale such as sunlight, wind, tides, waves, and geothermal heat. The increase in reliance of such energy resources further ensures that new development projects will not result in the waste of the finite energy resources. Therefore, by using electricity from SCE, the project would be in compliance with RR E-5. As a result, the project would ensure energy consumption to be kept to a minimum through high efficiency lighting, energy efficient appliances, and on-site renewable energy production.

Therefore, the project would not cause wasteful, inefficient, and unnecessary consumption of building energy during project operation, or preempt future energy development or future energy conservation. A less than significant impact would occur in this regard.

CONSISTENCY WITH APPLICABLE ENERGY PLANS
State and regional plans for renewable energy and energy efficiency include the California Energy Commission’s Integrated Energy Policy Report (IEPR), Title 24 standards, and CALGreen standards. The project would exceed 2022 Title 24 and CALGreen standards and incorporate all applicable energy efficiency measures in compliance with RR E-1 through E-5. The project proposes to remodel and reoccupy an existing building to use as an office building for Vista Charter Public School use. The proposed project would be compliant with all applicable goals and all other all applicable goals and policies by incorporating energy-, water- and waste-efficiency building features as per Title 24 standards. The project would also install water efficient features such as low-flow fixtures and water efficient and drought tolerant irrigation system to further reduce water consumption. Compliance with Title 24 and CALGreen standards would ensure the project’s consistency with the IEPR building energy efficiency recommendations, which would ensure project conformance with the State’s energy reduction goals. Less than significant impacts would occur in this regard.

4.6.3 Conclusion
The project is consistent with the General Plan Update. With implementation of RR E-1 through E-5, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe energy impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR E-1 Construction activities will be conducted in compliance with California Code of Regulations Section 2485, which requires that nonessential idling of construction equipment be restricted to five minutes or less.

RR E-2 At least 65 percent of all nonhazardous construction and demolition waste from nonresidential construction associated with future development in the plan area shall be recycled and/or salvaged for reuse in line with the 2016 California Green Building Standards Code Section 5.408 (California Code of Regulations, Title 24, Part 11).

RR E-3 New buildings implemented as part of the General Plan Update are required to achieve the current California Building Energy and Efficiency Standards (California Code of Regulations, Title 24, Part 6) and California Green Building Standards Code (California Code of Regulations, Title 24, Part 11).

RR E-4 Any appliances associated with development in the Plan Area shall meet the requirements of the 2012 Appliance Efficiency Regulations.

RR E-5 Development under the General Plan Update shall support the goals of the renewables portfolio standard, SB 350, and SB 100 to achieve a tiered increase in the use of renewable energy to 60 percent by 2030, and 100 percent by 2045.

4.7 Geology and Soils

4.7.1 GPU EIR Findings
The GPU EIR concluded that future development under the General Plan Update would be subject to potential seismic-related hazards including strong seismic ground shaking, seismicrelated ground failure, and landslides. Further, development associated with the General Plan Update could result in unstable geologic unit or soil conditions, including soil erosion, expansive soils, settlement and collapse, and subsidence. However, implementation of RR G-1, through G3 would reduce impacts to less than significant levels. Specifically, RR G-1 and G-2 require development to comply with the most recent version of the California Building Code and Municipal Code Chapter 8, Buildings and Structures, and RR G-3 requires all buildings or structures within the City that require plumbing fixtures be connected to a public sewer per Municipal Code Section 39-51, Mandatory Connections. The GPU EIR also concluded that development under the General Plan Update could impact known and unknown paleontological resources through grading and construction activities of undeveloped areas or redevelopment that requires more intensive soil excavation than in the past. Therefore, Mitigation Measures GEO-1 through GEO3 require monitoring based on the sensitivity level of sites for paleontological resources. Overall, the GPU EIR concluded that implementation of regulatory requirements and Mitigation Measures GEO-1 through GEO-3 would reduce geology and soil impacts to less than significant levels.

4.7.2 Project Analysis
The project site is located in a seismically active area, as is most of southern California. However, the project site is not located within a State-designated Alquist-Priolo Fault Hazard Zone. The nearest fault to the project site is the Bolsa-Fairview Fault (Newport-Inglewood Rose Canyon fault zone), located approximately 5.5 miles to the southwest. No active faults are known to cross the project site. Additionally, the site is not located in an area identified as a potential landslide hazard area by the State or City. However, the project site is located within an area susceptible to liquefaction. As described above, implementation of RR G-1 and G-2 would reduce impacts in this regard to less than significant levels. Consistent with the General Plan, compliance with existing regulations would ensure the proposed project would not result in a significant impact related to seismic hazards or liquefaction.

Construction of the proposed project would involve minimal ground-disturbing activities given the nature of the proposed improvements. As mentioned above, while construction activities may result in the potential for erosion to occur, implementation of RR G-1 and G-2 would reduce impacts in this regard to less than significant levels. Consistent with the General Plan, compliance with existing regulations including implementation of regulatory requirements would ensure the proposed project would not result in a significant impact related to erosion. No new or substantially more severe impacts would occur compared to the determinations of the GPU EIR, and no new mitigation measures are required.

Lateral spreading is a type of liquefaction-induced ground failure on mildly sloping ground.

However, the project site is located on relatively level ground, and implementation of the proposed project would not increase the risk of landslides. Therefore, no impacts related to lateral spreading would occur. Subsidence is the lowering of surface elevation due to changes occurring underground, such as the extraction of large amounts of groundwater. The proposed project would not involve the extraction of any groundwater, oil, or gas from the project site. Clay-based soils are typically susceptible to expansion. The geologic materials under the project site have very low expansive potential (plasticity index value less than 15) and are classified as nonCity Council 26 – 375 1/16/2024 Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 27
expansive in accordance with the 2022 California Building Code, Section 1803.5.3.14,15 As such, no impacts related to unstable or expansive soils would occur.

In compliance with RR G-3, construction and operation of the proposed project would not involve the use of septic tanks or alternative wastewater disposal systems. As such, compliance with existing regulatory requirements would ensure no impact related to the use of such systems would occur.

With regards to paleontological resources, the project site is disturbed and built out in nature; however, sediments in the project site are considered to have paleontological sensitivity increasing with depth. Specifically, the project site is underlain by silty sand of alluvial fan deposits (Qyfsa) which contain “low-to-high” paleontological sensitivity; refer to GPU EIR Figure 5.6-3, Paleontological Sensitivity. As such, in the event of paleontological resource discovery, the proposed project would comply with GPU EIR Mitigation Measure GEO-3, which requires construction work to halt within a 50-foot radius of a find. With adherence to the City’s existing requirements for paleontological resources, less than significant impacts related to paleontological resources would occur.

4.7.3 Conclusion
Overall, the project is consistent with the General Plan Update. With implementation of RR G-1 and G-2 and Mitigation Measure GEO-3 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no projectspecific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to geology and soils than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR G-1 Every public agency enforcing building regulations must adopt the provisions of the California Building Code (CBC), which is Title 24, Part 2 of the California Code of Regulations. The most recent version is the 2019 CBC (effective January 1, 2020). The CBC is updated every three years and provides minimum standards to protect property and public safety by regulating the design and construction of excavations, foundations, building frames, retaining walls, and other building elements to mitigate the effects of seismic shaking and adverse soil conditions.

The CBC also contains provisions for earthquake safety based on factors including occupancy type, the types of soil and rock on-site, and the strength of ground shaking with specified probability of occurring at a site.

RR G-2 Santa Ana Municipal Code, Chapter 8, Buildings and Structures. These codes address grading standards, excavation, and fills. This also includes compliance with regulations for unreinforced masonry structures in accordance with “Unreinforced Masonry Law,” found in California Government Code §§ 8875 et seq. The City of Santa Ana Building Official may place additional requirements upon the construction of infrastructure, buildings, and other improvements based on the findings from plan check, soils testing, and geotechnical investigations. 14 International Code Council, 2022 California Building Code, Title 24, Part 2, https://codes.iccsafe.org/content/CABC2022P1/chapter-18-soils-and-foundations, accessed July 26, 2023. 15 U.S. Department of Agriculture, Natural Resources Conservation Service, Web Soil Survey, https://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx, accessed July 26, 2023.

RR G-3 Santa Ana Municipal Code Section 39-51 requires that all buildings or structures within the city that require plumbing fixtures must be connected to a public sewer.

GEO-3 All Projects. In the event of any fossil discovery, regardless of depth or geologic formation, construction work shall halt within a 50-foot radius of the find until its significance can be determined by a qualified paleontologist. Significant fossils shall be recovered, prepared to the point of curation, identified by qualified experts, listed in a database to facilitate analysis, and deposited in a designated paleontological curation facility in accordance with the standards of the Society of Vertebrate Paleontology (2010). The most likely repository is the Natural History Museum of Los Angeles County. The repository shall be identified and a curatorial arrangement shall be signed prior to collection of the fossils.

4.8 Greenhouse Gas Emissions

4.8.1 GPU EIR Findings
The GPU EIR determined that implementation of Mitigation Measure GHG-1 would ensure that the City is tracking and monitoring the City’s GHG emissions to chart a trajectory to achieve the long-term, year 2050, GHG reduction goal set by Executive Order S-03-05. However, at this time, there is no plan past 2030 that achieves the long-term GHG reduction goal established under Executive Order S-03-05. As identified by the California Council on Science and Technology, the State cannot meet the 2050 goal without major advancements in technology. Advancements in technology in the future could provide additional reductions and allow the State and City to meet the 2050 goal, but in the meantime, the GPU EIR determined that buildout of the General Plan Update would result in significant and unavoidable GHG impacts. However, the GPU EIR determined that the General Plan Update would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions.

4.8.2 Project Analysis
The following section evaluates the potential GHG impacts that would result from implementation of the proposed project. This analysis is primarily based upon Attachment A, Air Quality/Greenhouse Gas/Energy Modeling Results.

THRESHOLDS OF SIGNIFICANCE
Amendments to CEQA Guidelines Section 15064.4 were adopted to assist lead agencies in determining the significance of the impacts of GHG emissions and gives lead agencies the discretion to determine whether to assess those emissions quantitatively or qualitatively. This section recommends certain factors to be considered in the determination of significance (i.e., the extent to which a project may increase or reduce GHG emissions compared to the existing environment; whether the project exceeds an applicable significance threshold; and the extent to which the project complies with regulations or requirements adopted to implement a plan for the reduction or mitigation of GHGs). The amendments do not establish a threshold of significance; rather, lead agencies are granted discretion to establish significance thresholds for their respective jurisdictions, including looking to thresholds developed by other public agencies or suggested by other experts, such as the California Air Pollution Control Officers Association (CAPCOA), so long as any threshold chosen is supported by substantial evidence (CEQA Guidelines Section 15064.7(c)). The California Natural Resources Agency has also clarified that the CEQA Guidelines amendments focus on the effects of GHG emissions as cumulative impacts, and therefore GHG emissions should be analyzed in the context of CEQA’s City Council 26 – 377 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 29
requirements for cumulative impact analyses (CEQA Guidelines Section 15064(h)(3)).16,17 A project’s incremental contribution to a cumulative impact can be found not cumulatively considerable if the project would comply with an approved plan or mitigation program that provides specific requirements to avoid or substantially lessen the cumulative problem within the geographic area of the project.18
The GPU EIR describes that if project emissions are below the 3,000 MTCO2e bright-line screening threshold, GHG emissions impacts would be considered less than significant. As such, the analysis utilizes the 3,000 MTCO2e per year numerical threshold of significance for GHG emissions and the methodology for evaluating the project’s impacts related to GHG emissions also focuses on its consistency with Statewide, regional, and local plans adopted for the purpose of reducing and/or mitigating GHG emissions.

PROJECT-RELATED GHG EMISSIONS
Project-related GHG emissions include emissions from direct and indirect sources. Direct projectrelated GHG emissions include emissions from construction activities, area sources, mobile sources, and refrigerants, while indirect sources include emissions from energy consumption, water demand, and solid waste generation. The CalEEMod, version 2022.1 was used to calculate project-related GHG emissions. Table 3, Estimated Greenhouse Gas Emissions, presents the estimated CO2, N2O, and CH4 emissions associated with the proposed project; refer to Attachment A for the CalEEMod outputs.

Refer to Attachment A, for detailed model input/output data.

Direct Project-Related Sources of Greenhouse Gases
Construction Emissions. Construction GHG emissions are typically summed and amortized over the lifetime of the project (assumed to be 30 years), then added to the operational emissions.19 The project would comply with RR GHG-1 which restricts non-essential idling of construction equipment and RR GHG-7 which ensures recycling and/or salvaging for reuse at minimum of 65 percent of the nonhazardous construction and demolition waste generated during construction.

As shown in Table 3, the proposed project would result in 2.58 MTCO2e per year construction emissions when amortized over 30 years (or a total of 77.3 MTCO2e in 30 years).

Area Source. Area source emissions were calculated using CalEEMod and project-specific land use data. Project-related area sources include natural gas consumption for space heating and exhaust emissions from landscape maintenance equipment, such as lawnmowers, shedders/grinders, blowers, trimmers, chain saws, and hedge trimmers used to maintain the landscaping of the site. The project would directly result in 0.14 MTCO2e per year from area source emissions; refer to Table 3.

Mobile Source. CalEEMod relies upon trip generation rates from the Vista Heritage Global Academy Expansion Trip Generation Assessment prepared by Urban Crossroads and dated July 24, 2023. The proposed project would generate 84 average daily trips without taking trip reduction from the existing uses on-site as they are currently vacant. The project would result in 19 The project lifetime is based on the standard 30-year assumption of the South Coast Air Quality Management District (South Coast Air Quality Management District, Draft Guidance Document – Interim CEQA Greenhouse Gas (GHG) Significance Threshold, October 2008).

City Council 26 – 379 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 31
approximately 56.00 MTCO2e per year of mobile source generated GHG emissions; refer to Table

3. Refrigerants. Refrigerants are substances used in equipment for air conditioning and refrigeration.

Most of the refrigerants used today are HFCs or blends thereof, which can have high GWP values.

All equipment that uses refrigerants has a charge size (i.e., quantity of refrigerant the equipment contains), and an operational refrigerant leak rate, and each refrigerant has a GWP that is specific to that refrigerant. CalEEMod quantifies refrigerant emissions from leaks during regular operation and routine servicing over the equipment lifetime, and then derives average annual emissions from the lifetime estimate. The proposed project would result in less than 0.01 MTCO2e per year of GHG emissions from refrigerants; refer to Table 3.

Indirect Project-Related Sources of Greenhouse Gases
Energy Consumption. Energy consumption emissions were calculated using CalEEMod and project-specific land use data. Southern California Edison (SCE) would provide electricity to the project site. Compliance with RR GHG-1 would ensure project’s consistency with 2022 Title 24 standards. The project would also exceed 2022 Title 24 standards, which has been not incorporated in CalEEMod as a conservative analysis. The project would indirectly result in 39.70 MTCO2e per year due to energy consumption; refer to Table 3.

Solid Waste. Solid waste associated with operations of the proposed project would result in 2.03 MTCO2e per year; refer to Table 3.

Water Demand. The project would comply with RR GHG-3 which ensures adherence to current CALGreen standards that requires increased water efficiency and reduce urban per capita water demand. The project operations would result in a demand of approximately 6.57 million gallons of water per year. Emissions from indirect energy impacts due to water supply would result in 3.78 MTCO2e per year; refer to Table 3.

Total Project-Related Sources of Greenhouse Gases
As shown in Table 3, the total amount of project-related GHG emissions from direct and indirect sources combined would total 104.23 MTCO2e per year. As such, the project would not exceed the 3,000 MTCO2e bright-line screening threshold and no new impacts would occur.

CONSISTENCY WITH APPLICABLE GHG PLANS, POLICIES, OR REGULATIONS The GHG plan consistency analysis for the project is based on the project’s consistency with the CARB 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan), and the City’s General Plan Update. The 2022 Scoping Plan describes the approach the State will take to achieve carbon neutrality by 2045. The General Plan Update contains goals, policies, and measures that would reduce GHG emissions within the City.

Consistency with the 2022 CARB Scoping Plan
The 2022 Scoping Plan identifies reduction measures necessary to achieve the goal of carbon neutrality by 2045 or earlier. Actions that reduce GHG emissions are identified for each Assembly Bill (AB) 32 inventory sector. Provided in Table 4, Consistency with the 2022 Scoping Plan: AB 32 GHG Inventory Sectors, is an evaluation of applicable reduction actions/strategies by emissions source category to determine how the project would be consistent with or exceed reduction actions/strategies outlined in the 2022 Scoping Plan.

Smart Growth / Vehicles Miles Traveled (VMT)
Reduce VMT per capita to 25% below
2019 levels by 2030, and 30% below
2019 levels by 2045
Consistent. The project would require installation of bicycle parking in accordance with the 2022 Title 24 standards and CALGreen Code, which would promote alternative mode of transportation to reduce VMT. Additionally, the project would be located near an existing Orange County Transportation Authority transit stop. As such, the project would be consistent with this action.

New Residential and Commercial Buildings
All electric appliances beginning 2026
(residential) and 2029 (commercial),
contributing to 6 million heat pumps

Consistent. The project is expected to consist of natural gas heating and/or cooking on-site. The City has not adopted an ordinance or program limiting the use of natural gas for on-site cooking and/or heating. However, if adopted, the project would comply with the applicable goals or policies limiting the use of natural gas equipment in the future. Furthermore, the project would install high efficiency lighting and appliances. As such, the project would be consistent with this action.

Construction Equipment
Achieve 25% of energy demand
electrified by 2030 and 75% electrified by
2045
Consistent. The City has not adopted an ordinance or program requiring electricity-powered construction equipment. However, if adopted, the project would be required to comply with the applicable goals or policies requiring the use of electric construction equipment in the future. As such, the project would be consistent with this action.

Non-combustion Methane Emissions
Divert 75% of organic waste from landfills
by 2025
Consistent. Senate Bill (SB) 1383 establishes targets to achieve a 50 percent reduction in the level of the Statewide disposal of organic waste from the 2014 level by 2020 and a 75 percent reduction by 2025. The law establishes an additional target that not less than 20 percent of currently disposed edible food is recovered for human consumption by 2025. The project would comply with local and regional regulations and recycle or compost 75 percent of waste by 2025 pursuant to SB 1383. As such, the project would be consistent with this action.

Source: California Air Resources Board, 2022 Scoping Plan, November 16, 2022.

Consistency with the General Plan Update
As previously stated, the project proposes to remodel and reoccupy an existing building to use as an office building. As an infill redevelopment project, the proposed project would require and produce less water, waste, and air quality pollutants compared to a new development.

Furthermore, the project would be compliant with General Plan Update Policy 4.1, Policy 4.2, Policy 4.3, Policy 4.4, and Policy 4.5 which incorporate energy-, water- and waste-efficiency building features as per Title 24 standards. The project would also be consistent with General Plan Update Policy 3.11, Policy 1.6, Policy 1.8, and Policy 1.12 by providing bicycle parking spaces on-site and due to the close proximity to the nearby transit station, which would promote alternative modes of transportation. As such, by complying with the City’s CAP and Title 24 standards, the project would also be consistent with the applicable GHG goals and policies in the General Plan Update.

Consistency Conclusion
In summary, the project’s characteristics render it consistent with Statewide, regional, and local climate change mandates, plans, policies, and recommendations. More specifically, the GHG plan consistency analysis provided above demonstrates that the project complies with the regulations and GHG reduction goals, policies, actions, and strategies outlined in the 2022 Scoping Plan, and City Council 26 – 381 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 33
General Plan Update. Consistency with these plans would reduce the impact of the project’s incremental contribution of GHG emissions. Accordingly, the project would not conflict with any applicable plan, policy, regulation, or recommendation adopted for the purpose of reducing GHG emissions. Impacts in this regard would be less than significant.

4.8.3 Conclusion
Overall, the project is consistent with the General Plan Update. With implementation of RR GHG1, GHG-2, GHG-3, and GHG -7, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe GHG impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR GHG-1 New buildings are required to achieve the current California Building Energy and Efficiency Standards (Title 24, Part 6) and California Green Building Standards Code (CALGreen) (Title 24, Part 11). The 2019 Building and Energy Efficiency Standards were effective on January 1, 2020. The Building Energy and Efficiency Standards and CALGreen are updated tri-annually.

RR GHG-2 Construction activities are required to adhere to California Code of Regulations, Title 13, Section 2499, which restricts nonessential idling of construction equipment to five minutes or less.

RR GHG-3 New buildings are required to adhere to the California Green Building Standards Code and Water Efficient Landscape Ordinance requirements to increase water efficiency and reduce urban per capita water demand.

RR GHG-7 California’s Green Building Standards Code (CALGreen) requires the recycling and/or salvaging for reuse at minimum of 65 percent of the nonhazardous construction and demolition waste generated during most “new construction” projects (CALGreen §§ 4.408 and 5.408). Construction contractors are required to submit a construction waste management plan that identifies the construction and demolition waste materials to be diverted from disposal by recycling, reuse on the project, or salvaged for future use or sale and the amount (by weight or volume).

4.9 Hazards and Hazardous Materials

4.9.1 GPU EIR Findings
The GPU EIR concluded that buildout of the proposed General Plan Update would include construction activities and operations that would transport, use, or dispose of hazardous materials in proximity to environmental justice (EJ) communities (i.e., disadvantaged communities). Such activity could create a significant hazard to the public or the environment given the proximity of hazardous materials sites which are considered open cases, existing lead-contaminated soils, existing buildings containing asbestos-containing materials (ACM) and/or lead-based paint (LBP), and existing and planned industrial uses throughout the City. Further, there are parts of the City that are within the vicinity of the John Wayne Airport Compatibility Land Use Plan. However, the existing federal, State, and regional regulatory framework regarding hazardous materials is substantial and would apply to all future construction and operation of uses within the City.

Further, the GPU EIR included regulatory requirements that are specific to existing hazards and City Council 26 – 382 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 34
hazardous materials conditions in the City. Compliance with all applicable regulations would be required of future development in the City and would reduce the proposed General Plan Update’s impacts related to hazards or hazardous materials to a less than significant level.

According to GPU EIR Figure 2-1, EJ Communities, Neighborhoods, and Focus Areas, the project site is located within an EJ community. However, the proposed project would neither develop any new industrial uses, nor be located on or adjacent to a site listed under Table 5.8-5, Existing Hazardous Materials Sites, of the GPU EIR. Construction activities would use limited amounts of hazardous materials in the form of paints, solvents, glues, roofing materials, and other common construction materials for the proposed building remodel and outdoor play area. Construction activities may include the use of machinery and other equipment that require fueling or maintenance/servicing. These types of materials are not acutely hazardous, and all storage, handling, use, transport, and disposal of these would be required to conform to existing laws and regulations of the California Department of Toxic Substances Control (DTSC), United States Environmental Protection Agency (U.S. EPA), Occupational Safety & Health Administration (OSHA), and Orange County Health Care Agency (OCHCA) Environmental Health Division, which would ensure that all potentially hazardous materials are used and handled in an appropriate manner and would minimize the potential for safety impacts to occur. Additionally, the storage, handling, use, transport, and disposal of these hazardous materials would cease once construction is complete. Project compliance with RR HAZ-1 would ensure hazardous materials and hazardous wastes are transported in compliance with any applicable State and federal requirements; RR HAZ-2 would ensure hazardous waste generation, transportation, treatment, storage, and disposal would be conducted in compliance with Subtitle C of the Resource Conservation and Recovery Act (Code of Federal Regulations, Title 40, Part 263); RR HAZ-4 would ensure demolition activities that could expose works or the public to ACMs or LBPs would be conducted in accordance with any applicable State and federal requirements, and RR HAZ-5 would ensure removal of hazardous materials be conducted as outlined in 29 CFR 1910.120 and 8 CCR 5192. Therefore, with adherence to existing regulations, impacts related to the routine transport, use, or disposal of hazardous materials and accidental release of hazardous materials would be less than significant.

4.9.2 Project Analysis
Vista Heritage Global Academy is adjacent to the south of the project site. As stated above, the proposed project would comply with existing regulations to minimize the risks associated with the exposure of sensitive receptors, including the existing school, to hazardous materials to a less than significant level. The types of uses that would emit or release hazardous or acutely hazardous materials into the environment are typically industrial manufacturing facilities, which is not proposed within the project site. The project would renovate an unused, vacant automobile repair building with a school district office and provide outdoor areas for existing students at the Vista Heritage Global Academy. Although the project site is located within 0.25-mile of an existing school, hazardous materials are not typically associated with the proposed institutional (i.e., district office) or recreational (i.e., play yard and play field) uses. Anticipated hazardous materials use during project operations may include minor cleaning products and the occasional use of pesticides and herbicides for landscape maintenance. Further, while the site is located adjacent to an existing railroad alignment, it is currently under construction for future electric street cars.

Compliance with applicable laws and regulations regarding the handling and transport of hazardous materials, including RR HAZ-1, HAZ-2, HAZ-4, and HAZ-5 would ensure impacts would be less than significant.

The project site is not listed in the State Water Resources Control Board (SWRCB) GeoTracker system which includes leaking underground fuel tank sites and spills, leaks, investigations, and City Council 26 – 383 1/16/2024

December 2023 Page 35
cleanups sites; or the DTSC EnviroStor Data Management System which includes Cortese sites; or the U.S. EPA’s database of regulated facilities.20 As such, impacts related to hazardous materials sites would be less than significant.

The John Wayne Airport is adjacent to the City’s southeast boundary. The project site is approximately five miles northwest of the John Wayne Airport. The John Wayne Airport Compatibility Land Use Plan regulates land use development within the vicinity of the airport.

According to Figure 5.8-5, John Wayne Airport Safety Compatibility Zones, and Figure 5.8-6, Height Restrictions per Federal Air Regulations Part 77, of the GPU EIR, the project site is located outside of the John Wayne Airport’s safety compatibility zone and height restriction areas. As such, the proposed project would not result in a safety hazard or excessive noise for people residing and working in the project area. Impacts would be less than significant.

Construction equipment and materials staging would occur within the project site. During construction, vehicular access would be provided via existing access points along North Fairview Street and West 5th Street. Operation of the proposed project would not result in population growth or changes to the existing circulation system. All driveways would be 20 feet in width; the modified student drop-off and pick-up area would have a 20-foot turn radius and 72-foot-wide turnaround, providing a more immediate point of access to the proposed development from West 5th Street and adequate space for emergency vehicle access. As such, the proposed project would not interfere with operations of the City’s Emergency Operations Center and would not interfere with operations of emergency response agencies or with coordination and cooperation between such agencies; thus, impacts to emergency response planning would be less than significant.

The City of Santa Ana is not in a designated fire hazard zone. As such, no impact related to the risk of wildland fires would occur.

4.9.3 Conclusion
Overall, the project is consistent with buildout of the General Plan Update. With implementation of RR HAZ-1, HAZ-2, HAZ-4, and HAZ-5 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to hazards and hazardous materials than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR HAZ-1 Hazardous materials and hazardous wastes will be transported to and/or from projects developed under the General Plan Update in compliance with any applicable state and federal requirements, including the U.S. Department of Transportation regulations listed in the Code of Federal Regulations (Title 49, Hazardous Materials Transportation Act); California Department of Transportation standards; and the California Occupational Safety and Health Administration standards.

RR HAZ-2 Hazardous waste generation, transportation, treatment, storage, and disposal will be conducted in compliance with Subtitle C of the Resource Conservation and 20 California Environmental Protection Agency, Cortese Listing, https://calepa.ca.gov/sitecleanup/corteselist/, accessed July 6, 2023.

4.10 Hydrology and Water Quality

4.10.1 GPU EIR Findings
The GPU EIR concluded that compliance with local, State, and federal regulations and the policies of the proposed General Plan Update would reduce buildout impacts related to groundwater, drainage, hydrology, and water quality. Individual projects would be required to incorporate project-specific source control and treatment Best Management Practices (BMPs), incorporate low impact design (LID)/site design, and comply with applicable regulatory requirements to ensure compliance with regulations governing water quality (e.g., the City’s Local Implementation Plan [LIP], Orange County Drainage Area Management Plan and National Pollutant Discharge Elimination System [NPDES] Municipal Separate Storm Sewer System [MS4] Permit from the Santa Ana Regional Water Quality Control Board (RR HYD-4), and the City’s Model Water Quality Management Plan [WQMP]).

4.10.2 Project Analysis
Construction activities have the potential to degrade water quality through the exposure of surface runoff to exposed soils, dust, and other debris at the project site as well as increase erosion and/or siltation. As the project would develop a 0.9-acre site, the project would not be required to obtain coverage under the NPDES Construction General Permit (CGP). However, project compliance City Council 26 – 385 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 37
with RR HYD-5 would ensure adherence to Municipal Code Chapter 18 Article IV regarding prohibitions on illicit connections and discharges, urban runoff control measures, and permit requirements. As a result, water quality impacts associated with construction activities would be less than significant.

As the project would introduce new uses (i.e., office and outdoor areas) to the project site, development of a WQMP consistent with the prevailing terms and conditions of the City’s LIP, Orange County Drainage Area Management Plan and NPDES MS4 Permit from the Santa Ana Regional Water Quality Control Board, i.e., RR HYD-4, and the City’s Model WQMP would be required. The WQMP would include LID/site design and project-specific BMPs to ensure water quality standards or waste discharge requirements are not violated, and to prevent substantial erosion or siltation on- or offsite. Further, existing drainage facilities within the public right-of-way (i.e., West 5th Street and North Fairview Street) would be maintained. Therefore, with compliance to existing regulations to control construction stormwater runoff during operation, impacts related to water quality standards, waste discharge requirements, and storm water drainage would be less than significant, consistent with the General Plan Update.

Given the proposed uses, the project would not result in substantial population growth within Santa Ana. According to the GPU EIR, projected water demand from the proposed General Plan Update at buildout, including development of the proposed project, is well within the projected total water demand for 2040 in the City of Santa Ana 2015 Urban Water Management Plan for normal, dry year, and multiple dry year scenarios. Additionally, because the project site was formerly occupied by automotive repair businesses and associated parking area, development of the proposed project would not interfere with groundwater recharge. Therefore, consistent with the General Plan Update, the proposed project would result in less than significant impacts related to groundwater.

The GPU EIR determined that sites within the West Santa Ana Boulevard Focus Area that would be updated from single-family to multi-family residential use would become areas with increased impervious surfaces, and as a consequence, areas of increased stormwater runoff peak flows compared to pre-project conditions. The proposed project would renovate an existing building, formerly occupied by automobile repair businesses, into an office building; no change in density is proposed and the building footprint would not change from existing conditions. Additionally, the project proposes new landscaped areas, including a community garden, play field, and play yard, where paved surface parking currently exists. As such, the project would reduce the amount of impervious areas on the project site compared to existing conditions.

According to Figure 5.9-4, City of Santa Ana Flood Zones, of the GPU EIR, the project site is not within a 100-year flood hazard area as designated by the Federal Emergency Management Agency (FEMA). According to Figure 5.9-5, Dam Inundation Areas, of the GPU EIR, the project site is within both the Santiago Creek Dam and Prado Dam inundation areas. However, the Santiago Creek Dam has been assessed by the California Division of Safety of Dams (DSOD) to have no existing or potential dam safety deficiencies and the U.S. Army Corps of Engineers’ Dam Safety Program is actively implementing risk-reduction measures to remediate the Prado Dam, including routine inspections and ongoing monitoring, spillway modifications to improve downstream flow, and public outreach, to ensure potential inundation hazards are minimized or eliminated.21 The GPU EIR determined that seiche occurrence is lower within inundation zones, 21 U.S. Army Corps of Engineers, Corps reclassifies Prado Damn, implements risk-reduction measures, https://www.spl.usace.army.mil/Media/News-Releases/Article/1849301/corps-reclassifies-prado-dam-implementsrisk-reduction-measures/, May 15, 2019.

and that the City is too far inland to be at risk of a tsunamis. As such, implementation of the proposed project would result in less than significant impacts in this regard.

4.10.3 Conclusion
Overall, the project is consistent with the General Plan Update. With implementation of RRs HYD4 and HYD-5 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to hydrology and water quality than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR HYD-4 All development pursuant to the General Plan Update shall comply with the requirements of the Orange County MS4 Permit (Order R8-2009-0030, NPDES No. CAS618030, as amended by Order No. R8-2010 0062). The MS4 Permit requires new development and redevelopment projects to:
• Control contaminants into storm drain systems
• Educate the public about stormwater impacts
• Detect and eliminate illicit discharges
• Control runoff from construction sites
• Implement best management practices and site-specific runoff controls and treatments for new development and redevelopment.

RR HYD-5 All development pursuant to the General Plan Update shall comply with the requirements detailed in Chapter 18 Article IV of the Santa Ana Municipal Code.

4.11 Land Use and Planning

4.11.1 GPU EIR Findings
The GPU EIR concluded that the General Plan Update’s policies would encourage the preservation or enhancement of the existing residential communities through infill development, open space opportunities, and development of compatible uses that would enhance the existing character of the City. A primary goal of the General Plan Update is to preserve and improve the character and integrity of existing neighborhoods and districts; specific policies would reduce the conflict between contrasting land uses and enhance neighborhoods by responsibly integrating new development into existing communities. None of the changes in the General Plan Update would affect plans, policies, or regulations of other agencies that have jurisdiction within the City, including the Airport Environs Land Use Plan for the John Wayne Airport, the Orange County Transportation Authority (OCTA) Congestion Management Plan, and the Southern California Association of Governments (SCAG) 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). As individual projects are considered by the City, each would be subject to a variety of federal, State, and locally adopted plans designed to mitigate environmental impacts or to preserve important resources. As such, impacts associated with the General Plan Update with regards to land use and planning would be less than significant.

4.11.2 Project Analysis
The proposed project would remodel and reoccupy a building formerly occupied by an automotive repair use as an office building for Vista Charter Public Schools. The project would also redevelop the shared surface parking lot into an outdoor area consisting of a community garden, a play field, and a play yard for administrative staff and existing students associated with the adjacent school; the outdoor areas would not be open to the public. Ancillary improvements include landscaping fencing along the perimeters of the proposed outdoor areas, and expansion of the existing parking lot. Similar to existing conditions, the site would remain accessible from North Fairview Street via two driveways to the west, and two alleys connecting to West 5th Street to the south and southeast. The student drop-off and pick-up area and internal site circulation would be slightly modified to accommodate the outdoor learning garden space and the outdoor play areas. The project site is not within a residential community; it is surrounded by industrial uses, with nearby residential uses separated by an existing railroad alignment. As such, development of the proposed project would not divide any established surrounding residential community.

The project is subject to the policies and/or regulations of the General Plan Update and Municipal Code at the local level. As previously stated, the project site has a land use designation of Industrial/Flex-Low (FLEX-1.5) and is within the Light Industrial (M1) and Specific Development No. 82 (SD-82) zones. The FLEX-1.5 designation allows for various office uses, a maximum FAR of 1.5 and a maximum building height of three stories. The proposed project would renovate an existing 5,837-square foot building as an office building for Vista Charter Public Schools. The building is located on a 0.9-acre (39,204 square-foot) site, thus providing an FAR of 0.15. The existing building height would remain the same at 19 feet and four inches. As such, the project would meet the design standards of the FLEX-1.5 designation.

Further, as detailed in Table 5, General Plan Update Land Use Element Project Consistency Analysis, the proposed project would be consistent with the applicable General Plan Update Land Use Element goals and policies.

Table 5

Source: City of Santa Ana, Golden City Beyond, Santa Ana General Plan Land Use Element, April 2022.

Per RR LU-1, the project must comply with the applicable provisions of Chapter 41 (Zoning) of the City of Santa Ana Municipal Code. Permitted uses in the SD-82 zone are the uses permitted in the M1 zone as specified in Municipal Code Chapter 41, Article III, Division 18, M1 (Light Industrial), and schools by right and churches with a conditional use permit. Further, it is noted that the operational and development standards for the permitted and conditionally permitted Light Industrial Uses within the SD-82 zone shall be consistent with the operational and development standards found in Municipal Code Chapter 41, Article III, Division 18. To allow the use of the former automotive repair building for the proposed office use, a Zone Change would be required to modify the existing M1 zone to SD-82 to be consistent with the majority of the Fairview Business Park. In addition to the proposed Zone Change, the project also proposes a Zoning Ordinance Amendment to amend the operational standards of the SD-82 zoning district to allow outdoor play areas. Under current SD-82 provisions, play areas for children are limited to indoors only. Upon approval of the above entitlements, the proposed project would be consistent with the requirements of the General Plan Update and project site’s zoning, and would not conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. Impacts would be less than significant.

4.11.3 Conclusion
As such, the project is consistent with the General Plan Update. With implementation of RR LU1 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to land use and planning than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR LU-1 Development associated with the General Plan Update would be designed and constructed in accordance with the applicable provisions of Chapter 41 (Zoning) of the City of Santa Ana Municipal Code. Development within specific plan areas, overlay areas, and specific development districts would implement zoning and City Council 26 – 390 1/16/2024

development standards that are applicable within these subareas in addition to those in the underlying zoning district.

4.12 Mineral Resources

4.12.1 GPU EIR Findings
According to the GPU EIR, the City does not have mineral resource sectors or active or inactive mines. Thus, implementation of the General Plan Update would not cause a loss of availability of known mineral resources. The City is mostly mapped as Mineral Resource Zone (MRZ) 3, which is an area where the significance of mineral deposits cannot be determined from available data.

The area in the southeast portion of the City is mapped as MRZ-1, which means an area where no significant mineral resources are present or there is little likelihood that significant mineral resources are present. A small area in the northeast corner of the City is mapped as MRZ-2, which means significant mineral resources are known or very likely. However, the GPU EIR determined that no loss of availability of a known mineral resource would occur, and impacts would be less than significant.

4.12.2 Project Analysis
According to Figure 5.11-1, Mineral Resource Zones, of the GPU EIR, which was adapted from the California Division of Mines and Geology map of mineral resource zones around the City, the project site, like most of Santa Ana, is mapped as MRZ-3. Therefore, implementation of the proposed project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State and would not result in the loss of availability of a locally important mineral resource recovery site delineated on a local General Plan, specific plan, or other land use plan. Therefore, consistent with the General Plan Update, no impact to mineral resources would occur.

4.12.3 Conclusion
As such, the project is consistent with buildout of the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to mineral resources than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.13 Noise

4.13.1 GPU EIR Findings
The GPU EIR concluded that implementation of the General Plan Update would result in significant temporary and permanent increases of noise levels throughout the City. Future development in accordance with the General Plan Update would generate both short-term and long-term noise level increases that may impact sensitive receptors. Implementation of the General Plan Update would include regulations designed to protect new sensitive land uses from excessive noise levels.

City Council 26 – 391 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 43
The GPU EIR described that Mitigation Measure N-1 would reduce potential noise impacts during construction to the extent feasible. However, due to the potential for proximity of construction activities to sensitive uses, the number of construction projects potentially occurring simultaneously, and the potential duration of construction activities, construction noise could result in a temporary substantial increase in noise levels above ambient conditions. Therefore, impacts would remain significant and unavoidable.

The GPU EIR determined that buildout of the General Plan Update would cause substantial traffic noise to increase on local roadways and could locate sensitive receptors in areas that exceed established noise standards. While Mitigation Measure N-2 would reduce potential interior noise impacts to future noise sensitive receptors below thresholds, there are no feasible or practical mitigation measures available to reduce project-generated traffic noise to less than significant levels for existing residences along affected roadways. Thus, the GPU EIR determined that traffic noise would remain a significant and unavoidable impact.

The GPU EIR discussed that construction activity would generate varying degrees of ground vibration, depending on the construction procedures and equipment, that has the potential to exceed the Federal Transit Administration (FTA) criteria for architectural damage (e.g., 0.12 inches per second peak particle velocity (PPV) for fragile or historical resources, 0.2 inches/second PPV for non-engineered timber and masonry buildings, and 0.3 inches/second PPV for engineered concrete and masonry). The GPU EIR determined that implementation of Mitigation Measure N-2 and adherence to associated performance standards, would reduce impacts to less than significant levels.

4.13.2 Project Analysis
The following section evaluates potential short- and long-term noise and ground-borne vibration impacts that would result from the proposed project.

THRESHOLDS OF SIGNIFICANCE
Exterior Noise Standards
Chapter 18, Article VI, Noise Control, of the Municipal Code provides criteria for ambient noise measurements as well as noise standards for residential, school, hospital, and church use. When non-transportation (stationary) noise is the noise source of concern, the City applies performance standards from Municipal Code Section 18.312, Exterior Noise Standards, to ensure that noise producers do not adversely affect noise-sensitive land uses. Table 6, Exterior Noise Standards, summarizes the City’s exterior noise standards.

Table 6
Exterior Noise Standards
Time Period Noise Levels (dBA)
L50 L25 L8 L2 Lmax
7:00 a.m. – 10:00 p.m. 55 60 65 70 75
10:00 p.m. – 7:00 a.m. 50 55 60 65 70
Note: A 5 dBA penalty shall be applied in the event of an alleged offensive noise such as impact noise, simple tones, speech, music, or any combination of thereof. If the measured ambient level exceeds any of the first four noise limit categories, the allowable noise exposure standard shall be increased to reflect the ambient noise level. If the ambient noise level exceeds the fifth noise limit category, the maximum allowable noise level under this category shall be increased to reflect the maximum ambient noise level.

December 2023 Page 44
Construction Noise Standards
The City’s noise ordinance exempts noise from construction activities that occur during the daytime. No construction is permitted outside of the hours identified in Municipal Code Section 18-314(e). Specifically, construction activities are restricted to the daytime hours of 7:00 am to 8:00 pm, Monday through Saturday. No construction activities are permitted on Sundays or federal holidays. Additionally, the Federal Transit Administration (FTA) established construction noise threshold of 80 dBA Leq for long-term construction projects, which is conservatively used to analyze the project’s construction noise impact.

Existing Conditions
The project vicinity is characterized by mostly residential and commercial land uses, with urbanrelated activities (i.e., auto repair mechanical equipment and parking areas) being the primary sources of stationary noise. Most of the existing noise in the project area is generated from traffic along surrounding roadways including North Fairview Street and West 5th Street.

Noise Measurements
In order to quantify existing ambient noise levels in the vicinity of the project site, Michael Baker International (Michael Baker) conducted three noise measurements on June 28, 2023; refer to Attachment B, Noise Data. The noise measurement sites were representative of typical existing noise exposure within and immediately adjacent to the project site. The three ten-minute measurements were taken between 11:00 a.m. and 12:00 p.m. Short-term (Leq) measurements are considered representative of the noise levels throughout the day and relate closely with the noise standards for the project area; refer to Table 7, Noise Measurements.

Meteorological conditions were partly cloudy skies, warm temperatures, with light wind speeds (6 miles per hour), and low humidity. Noise monitoring equipment used for the ambient noise survey consisted of a Brüel & Kjær Hand-held Analyzer Type 2250 equipped with a Type 4189 prepolarized microphone. The monitoring equipment complies with applicable requirements of the American National Standards Institute (ANSI) for sound level meters.

Noise-sensitive land uses are generally considered to include those uses where noise exposure could result in health-related risks to individuals, as well as places where quiet is an essential element of their intended purpose. Residential dwellings are of primary concern because of the potential for increased and prolonged exposure of individuals to both interior and exterior noise levels. Additional land uses such as parks, historic sites, cemeteries, and recreation areas are considered sensitive to increases in exterior noise levels. Schools, churches, hotels, libraries, and City Council 26 – 393 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 45
other places where low interior noise levels are essential are also considered noise-sensitive land uses.

The closest sensitive receptors to the project site are residential uses located approximately 100 feet to the north of the project site and the existing Romero-Cruz Academy School is located approximately 100 feet to the west.

PROJECT-GENERATED NOISE IMPACTS
It is difficult to specify noise levels that are generally acceptable to everyone; noise that is considered a nuisance to one person may be unnoticed by another. Standards may be based on documented complaints in response to documented noise levels or based on studies of the ability of people to sleep, talk, or work under various noise conditions.

Short-term Construction Impacts
The project involves remodeling activities associated with paving, building construction, and architectural coating applications and would be completed in approximately eight months. Typical noise levels generated by construction equipment are shown in Table 8, Maximum Noise Levels Generated by Typical Construction Equipment. Operating cycles for these types of construction equipment may involve one or two minutes of full power operation followed by three to four minutes at lower power settings. Other primary sources of acoustical disturbance would be due to random incidents, which would last less than one minute (such as dropping large pieces of equipment or the hydraulic movement of machinery lifts).

Construction noise levels in the project vicinity would fluctuate depending on the particular type, number, and duration of usage for the varying equipment. The effects of construction noise largely depend on the type of construction activities occurring on any given day, noise levels generated by those activities, distances to noise-sensitive receptors, and the existing ambient noise environment in the receptor’s vicinity. Construction generally occurs in several discrete phases, with each phase requiring different equipment with varying noise characteristics. These phases alter the characteristics of the noise environment generated on the proposed project site and in the surrounding community for the duration of the construction process.

Noise levels depicted in Table 8 represent maximum sound levels (Lmax), which are the highest individual sound occurring at an individual time period. The closest sensitive receptors to the City Council 26 – 394 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 46
project site are single-family residences and the Romero-Cruz Academy School located approximately 100 feet to the north and west of the project site, respectively. As shown in Table 8, construction noise levels could range between 71 dBA and 78 dBA at 100 feet. Although sensitive receptors may be exposed to increased noise levels during project construction, construction noise levels would not exceed the FTA threshold of 80 dBA. In addition, construction activities are exempt from the City’s thresholds as it is a normal part in the urban life. Furthermore, compliance with RR NOI-2 would ensure that the project construction activities would comply with the City’s Noise Ordinance detailed in Municipal Code Section 18-314(e) and occur only Monday through Saturday between 7:00 a.m. and 8:00 p.m. As such, project construction noise would be exempt from the City’s noise standards and compliance with hours of construction activities would reduce impacts to less than significant in this regard.

Long-term Operational Impacts
Mobile Noise
Implementation of the project would result in vehicle use on adjacent roadways, thereby increasing vehicular noise in the site vicinity. As determined by the California Department of Transportation (Caltrans) in the Technical Noise Supplement to the Traffic Noise Analysis Protocol (September 2013), a doubling in roadway traffic volumes is required to generate any noticeable increase in roadway noise levels.22
According to the Vista Heritage Global Academy Expansion Trip Generation Assessment prepared by Urban Crossroads and dated July 24, 2023, the proposed project would generate 84 average daily trips without taking trip reductions from the existing uses as they are currently vacant. The nearest major roadway segment to the project vicinity is Fairview Street which currently experiences approximately 40,000 average daily trips.23 As such, the project’s minimal trip generation (approximately 84 average daily trips) would not double existing traffic volumes along nearby roadways and an increase in traffic noise along local roadways would be imperceptible. Project-related traffic noise impacts would be less than significant.

Stationary Noise Impacts
Stationary noise sources associated with the proposed project would include mechanical equipment, parking activities, and outdoor play field areas. These noise sources are typically intermittent and short in duration. Noise has a decay rate due to distance attenuation, which is calculated based on the Inverse Square Law. Based upon the Inverse Square Law, sound levels decrease by 6 dBA for each doubling of distance from the source.24 All stationary noise activities would be required to comply with RR NOI-3 in accordance with the City’s noise standards.

Mechanical Equipment
Heating Ventilation and Air Conditioning (HVAC) units typically generate noise levels of approximately 66 dBA Leq at three feet from the source.25 HVAC units are expected to be located 22 California Department of Transportation, Technical Noise Supplement to the Traffic Noise Analysis Protocol, September 2013. 23 City of Santa Ana, City of Santa Ana General Plan Circulation Element, https://storage.googleapis.com/proudcity/santaanaca/uploads/2022/04/Circulation-Element.pdf, accessed on July 28, 2023. 24 Cyril M. Harris, Noise Control in Buildings, 1994. 25 Berger, Elliott H., et al., Noise Navigator Sound Level Database with Over 1700 Measurement Values, June 26, 2015.

City Council 26 – 395 1/16/2024

December 2023 Page 47
on the center of the rooftop and the closest sensitive receptor to the HVAC units is the existing Vista Charter Global Academy located at approximately 130 feet to the south. At the distance of 130 feet, HVAC noise levels would attenuate to approximately 33 dBA. Therefore, HVAC noise levels would be below the City’s exterior daytime standards of 55 dBA and nighttime standards of 45 dBA in accordance with RR NOI-3 and would be lower than existing ambient noise levels of

66.2 dBA near the nearest sensitive receptor (Vista Charter Global Academy); refer to Table 7.

Furthermore, HVAC equipment are already present on the rooftop of the existing building and the project would not introduce additional HVAC equipment. Therefore, the nearest sensitive receptors would not be directly exposed to substantial noise from on-site HVAC equipment and impacts would be less than significant.

Parking Areas
Traffic associated with parking activities is typically not of sufficient volume to exceed community noise standards, which are based on a time-averaged scale such as the CNEL scale. However, the instantaneous maximum sound levels generated by a car door slamming, engine starting up and car pass-by may be an annoyance to adjacent noise-sensitive receptors. Estimates of the maximum noise levels associated with some parking lot activities are presented in Table 9, Typical Noise Levels Generated by Parking Lots.

Table 9
Typical Noise Levels Generated by Parking Lots
Noise Source Maximum Noise Levels
at 50 Feet from Source
Car door slamming 61 dBA Leq
Car starting 60 dBA Leq
Car idling 53 dBA Leq
Source: Kariel, H. G., Noise in Rural Recreational Environments, Canadian Acoustics 19(5), 3-10, 1991.

The project would provide 63 parking spaces on-site. As shown in Table 9, parking activities can result in noise levels up to 61 dBA at a distance of 50 feet. The proposed project would have intermittent parking activities noise due to the movement of vehicles. The nearest sensitive receptors are the existing single-family residences located approximately 100 feet from the proposed parking spaces on the north of the project site. At this distance, noise levels from parking activities would range from 47 dBA to 55 dBA. As previously noted, parking lot noise are instantaneous noise levels compared to noise standards in the CNEL scale, which are averaged over time. As a result, actual noise levels over time resulting from parking lot activities would be far lower than what is identified above. Further, parking activity noise currently exists within the project site and would not represent a new source of noise. Impacts would be less than significant in this regard.

Outdoor Play Area
The proposed project proposes outdoor play areas along the northern boundary of the existing Vista Charter Global Academy building, in the southern portion of the project site. The play area has the potential to be accessed by groups of children intermittently for gathering, etc. Noise generated by groups of people (i.e., crowds) is dependent on several factors including vocal effort, impulsiveness, and the random orientation of the crowd members. Crowd noise is estimated at 60 dBA at one meter (3.28 feet) away for raised normal speaking.26 This noise level would have a +5 dBA adjustment for the impulsiveness of the noise source, and a -3 dBA adjustment for the 26 M.J. Hayne, et al, Prediction of Crowd Noise, Acoustics, November 2006.

City Council 26 – 396 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 48
random orientation of the crowd members.27 Therefore, crowd noise would be approximately 62 dBA at one meter from the source (i.e., the outdoor gathering areas).

The nearest sensitive receptors would be the residential uses to the north of the project site, located approximately 200 feet from the proposed outdoor play areas. Therefore, crowd noise at the nearest sensitive receptor would be 26 dBA, which would not exceed the City’s noise standards for residential uses in accordance with RR NOI-3 (i.e., 55 dBA for daytime and 45 dBA for nighttime) and would be lower than existing ambient noise levels of 51.1 dBA near the nearest sensitive receptors (residential uses to the north); refer to Table 7. As a result, noise generated from the outdoor play area would be further reduced. As such, project noise associated with outdoor play area would have a less than significant impact would occur in this regard.

PROJECT-GENERATED VIBRATION IMPACTS
Project construction activities can generate varying degrees of groundborne vibration, depending on the construction procedure and the construction equipment used. Operation of construction equipment generates vibrations that spread through the ground and diminish in amplitude with distance from the source. The effect on buildings located in the vicinity of the construction site often varies depending on soil type, ground strata, and construction characteristics of the receiver building(s). The results from vibration can range from no perceptible effects at the lowest vibration levels, to low rumbling sounds and perceptible vibration at moderate levels, to slight damage at the highest levels. Groundborne vibrations from construction activities rarely reach levels that damage structures.

This evaluation uses the FTA architectural damage criterion for continuous vibrations of 0.3 in/sec PPV for engineered concrete and masonry. Typical vibration produced by construction equipment is illustrated in Table 10, Typical Vibration Levels for Construction Equipment.

Table 10

PPV equip = PPV ref x (25/D)1.1

D = the distance from the equipment to the receiver
Source: California Department of Transportation, Transportation and Construction Vibration Manual, April 2020.

The nearest sensitive receptor structure is the existing single-family buildings located approximately 100 feet to the north of anticipated project site. As indicated in Table 10, vibration velocities from typical heavy construction equipment used during project construction would range from 0.0004 to 0.0111 in/sec PPV at 100 feet from the source of activity, which would not exceed the 0.3 in/sec PPV threshold. As such, the impacts would be less than significant.

The proposed project use would not generate operational groundborne vibration that could be felt by surrounding uses. Additionally, the proposed project would not involve railroads or substantial 27 Ibid.

City Council 26 – 397 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 49
heavy truck operations, and therefore would not result in operational vibration impacts at surrounding uses. No impacts would occur in this regard.

EXCESSIVE NOISE NEAR AIRPORTS
The nearest airport to the project site is the John Wayne Airport located approximately five miles to the southeast. The project site is not located within two miles of the airport. Additionally, the project site is not located within the vicinity of a private airstrip or related facilities. Therefore, project implementation would not expose people residing or working in the project area to excessive noise levels associated with aircraft. As such, the impacts would be less than significant.

NOISE IMPACTS TO ON-SITE SENSITIVE RECEPTORS
The project site is located adjacent to an existing railroad alignment. The railroad is currently not operational and is being developed to build a fixed guideway system, OC Streetcar. Due to the proximity of the project site to the railroad alignment, future operations of the railroad have the potential to elevate existing noise levels, particularly during streetcar operations and crossing signal noise along Fairview Street located at approximately 90 feet from the project site. Based on the Santa Ana and Garden Grove Fixed Guideway Project Noise and Vibration Technical Report, prepared by URS Corporation and dated February 2012, noise from the operation of future streetcars have the potential to range from approximately 43 dBA Ldn during crossing activities to 59 dBA Ldn during blowing warning horn at approximately 100 feet. As such, exterior noise levels impacting the project site from the operation of future streetcars would not increase the existing ambient noise levels; refer to Table 7. Furthermore, future noise level impacts from OC Streetcar operations would be within the normally acceptable range of 50 to 70 dBA CNEL.28 As such, noise impacts to on-site sensitive receptors would be less than significant.

4.13.3 Conclusion
As such, the project is consistent with buildout of the General Plan Update. Upon implementation of RR NOI-2 and NOI-3, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to noise and vibration than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR NOI-2 Construction Noise Sources: Section 18-314(e) of the Santa Ana Municipal code prohibits construction activities to the hours of 7:00 AM to 8:00 PM Monday through Saturday.

RR NOI-3 Stationary Noise Sources: Section 18.312 of the Santa Ana Municipal Code establishes standards for stationary noise sources.

4.14 Population and Housing

4.14.1 GPU EIR Findings
The GPU EIR concluded that full buildout of the General Plan Update would result in a population of 431,629 and the City’s 2045 population growth would be approximately 20 percent greater than the Orange County Council of Government (COG) 2045 population projections for the City.

Furthermore, it is anticipated that General Plan Update buildout would result in 115,053 dwelling units, which exceeds the Orange County COG’s housing projections for the City by 38 percent.

As such, impacts are considered potentially significant. However, there are no feasible mitigation measures to mitigate the population and housing growth anticipated for the buildout of the General Plan Update. Further, the purpose of the General Plan Update is to provide orderly growth in the City through the distribution, location, balance, and extent of land uses, and the General Plan Update would provide more housing opportunities than currently exist during a time when there is a housing crisis. Still, impacts to population and housing were determined to be significant and unavoidable.

4.14.2 Project Analysis
The project proposes to remodel and reoccupy a building formerly occupied by an automotive repair use as an office building for Vista Charter Public Schools. Vista Charter Public Schools operates six public charter schools in Los Angeles and Orange County and serves a total of 1,500 students. The proposed project creates an opportunity to have a district office located next to the organization’s largest school, Vista Heritage Global Academy. While the headquarters would provide new office and conference space for employees of Vista Charter Public Schools, it is not anticipated that the project would generate new employment opportunities within the existing organization. Additionally, proposed outdoor areas would serve existing students of the adjoining Vista Heritage Global Academy and would not increase existing school capacity. As a result, the proposed project would not directly or indirectly result in substantial unplanned population growth in the area or displace substantial numbers of existing people or housing. Further, as discussed in Section 4.11, Land Use and Planning, the project would meet the design standards of the FLEX-1.5 designation and would be consistent with the applicable General Plan Update Land Use Element goals and policies. Therefore, consistent with the General Plan Update, less than significant impacts to population and housing would occur.

4.14.3 Conclusion
As such, the project is consistent with of the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to population and housing than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.15 Public Services

4.15.1 GPU EIR Findings
The GPU EIR concluded that introduction of new structures and additional residents and workers to the City would increase the demand for fire and police protection services. However, funding City Council 26 – 399 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 51
for additional staff, equipment, and facilities would come from property taxes, grants, special revenue funds, and the City’s general fund as future development accommodated by the General Plan Update occurs. The additional demand for fire and police protection services due to population growth generated within the City would be satisfied through these sources.

Additionally, the GPU EIR determined that school districts within the City would have the capacity to accommodate future students generated as a result of the proposed General Plan Update.

Should there be a need to expand or construct new facilities, funding for new schools would be obtained from the mitigation fee program pursuant to Senate Bill (SB) 50, and State and federal funding programs. Pursuant to Section 65996 of the Government Code, payment of school fees is deemed to provide full and complete school facilities mitigation. Further, while library services would also experience an increase in demand, property taxes and library fines and fees are expected to satisfy this impact; overall, impacts would be less than significant.

4.15.2 Project Analysis
As discussed above, buildout of General Plan Update is projected to increase the population of the City beyond growth projections. However, the project would not contribute to population growth as the proposed district office would serve existing employees and the outdoor recreation areas would serve existing students. As such, the proposed project would not increase demands on existing public services. Additionally, compliance with RR FP-1 would ensure that the proposed project would meet the fire regulations outlined in California Health and Safety Code, and RR SS1 would ensure that the proposed project would pay school development fees authorized by Section 65996 of the California Government Code. The project would also generate property tax which further fund fire and police protection services and library services. Therefore, consistent with the General Plan Update, less than significant impacts would occur.

4.15.3 Conclusion
As such, the project is consistent with the General Plan Update. With implementation of RR FP1 and SS-1 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to public services than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures:

RR FP-1 New buildings are required to meet the fire regulations outlined in California Health and Safety Code (Sections 13000 et seq.).

RR SS-1 New residential and commercial development shall pay development fees authorized by Section 65996 of the California Government Code to be “full and complete school facilities mitigation.”

4.16 Recreation

4.16.1 GPU EIR Findings
The GPU EIR concluded that buildout of the General Plan Update would generate the demand for approximately 564 acres of parkland and recreational facilities assumed to serve the 2045 population. The City is essentially built-out and very limited vacant land is available to be developed with new recreational opportunities. New or expanded facilities would need to occur City Council 26 – 400 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 52
outside of park-designated parcels and the development of these facilities may have an adverse physical effect on the environment, including impacts relating to air quality, biological resources, lighting, noise, and traffic. As such, it was determined that even with implementation of Mitigation Measure REC-1, which would require preparation of a public park utilization study, followed by further mitigation such as land dedication or fair shares contributions for projects resulting in a significant impact based on the study. impacts to recreation were determined to be significant and unavoidable.

4.16.2 Project Analysis
As discussed, the project is not anticipated to generate population growth. As such, it is not anticipated that the project would increase demand on the City’s existing parks or recreation facilities. Rather, the project proposes to redevelop the existing shared surface parking lot in the southern portion of the site into an outdoor area consisting of an approximately 2,297-square foot community garden, an approximately 7,372-square foot play field, and an approximately 4,640- square foot play yard. Outdoor areas would serve existing students of the adjoining Vista Heritage Global Academy and would not increase existing school capacity. As such, while the project does not provide additional public parkland, it would alleviate demand on existing City recreation facilities that may otherwise be utilized by the students. Environmental impacts associated with the construction of these outdoor areas are addressed in the respective topical sections of this document (i.e., aesthetics, air quality, biological resources, cultural resources, greenhouse gas emissions, noise, and transportation). Further, the proposed project would be required to either dedicate land or pay in-lieu impact fees per Municipal Code Chapter 34, Article VIII, and Chapter 35, Article IV as well as the Quimby Act. The fees collected would be used for development and improvement of public parks and recreation facilities throughout the City. Thus, the proposed project would not cause or accelerate substantial physical deterioration of existing parks or other recreational facilities nor include or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment. Impacts would be less than significant.

4.16.3 Conclusion
As such, the project is consistent with the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to recreation than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.17 Transportation

4.17.1 GPU EIR Findings
The GPU EIR determined that buildout of the General Plan Update would not conflict with a program, plan, ordinance, or policy addressing the circulation system following implementation of RR T-1. RR T-1 requires design and operation of a multimodal circulation system network with all users in mind including bicyclists, public transportation vehicles and riders, and pedestrians of all ages and abilities. The General Plan Update incorporates future networks and policies related to supporting transit, bicycles, and pedestrians in the City, which are consistent with regional and local planning efforts supporting these modes of travel. Additionally, implementation of the City Council 26 – 401 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 53
General Plan Update would result in a reduction of vehicle miles traveled (VMT) per service population in comparison to existing conditions at the time the GPU EIR was prepared and would achieve a VMT per service population of at least 15 percent lower than the Countywide VMT per service population. The GPU EIR also determined that buildout of the General Plan Update would not substantially increase hazards due to a geometric design feature or result in inadequate emergency access following implementation of RR T-2. RR T-2 requires projects pursuant to the General Plan Update to implement fire protection requirements as detailed in the Orange County Fire Authority’s Fire Prevention Guidelines and the California Fire Code.

4.17.2 Project Analysis
No changes are proposed to the existing circulation system in the project area and thus, the proposed project would not conflict with any program plan, ordinance or policy addressing the circulation system.

According to the City of Santa Ana Traffic Impact Study Guidelines (City Traffic Guidelines), a project can be presumed to have a less-than-significant VMT impact if the project satisfies one of the following screening criteria: 29
• Projects which serve the local community and have the potential to reduce VMT, such as neighborhood K-12 schools and local-serving retail less than 50,000 sq. ft. (Charter schools are excluded from this criteria).
• Projects that generate less than 110 net daily trips. • Projects located within Transit Priority Areas (TPAs); refer to City Traffic Guidelines Appendix A, Santa Ana Transit Priority Areas.
• Projects located in a low-VMT generating Traffic Analysis Zone (TAZ). City Traffic Guidelines Appendix B, VMT/SP in Santa Ana as Compared to Orange County Average, shows VMT per service population in Santa Ana as compared to the County average.

Low-VMT TAZs per Santa Ana’s threshold of significance are any TAZs generating VMT 15 percent below the County average.

The proposed project would renovate the approximately 5,837-square foot former automotive repair building as the Vista Charter Public Schools district office. According to the Vista Heritage Global Academy Expansion Trip Generation Assessment (Trip Generation Memo), prepared by Urban Crossroads, Inc. and dated July 24, 2023, the proposed project would generate approximately 84 average daily trips with 14 morning peak hour trips and 12 afternoon peak hour trips; refer to Attachment C, Trip Generation Memo. Therefore, the proposed project would meet the screening criteria related to projects that generate less than 110 net daily trips.

Additionally, according to City Traffic Guidelines Appendix A, Santa Ana Transit Priority Areas, the project site is located within a TPA, which is defined as a 0.5-mile radius around an existing or planned major transit stop (e.g., Metrolink Station, Streetcar Station, etc.) or an existing stop along a high-quality transit corridor. Thus, the project also meets the screening criteria related to projects located within TPAs.

December 2023 Page 54
Overall, the project meets two of the VMT screening requirements and thus, no VMT analysis would be required. The project is presumed to have a less than significant VMT impact.

Additionally, the project does not propose any changes to the City’s existing circulation system and would not introduce incompatible uses to area roadways. The site is accessible from North Fairview Street via two driveways to the west, and two alleys connecting to West 5th Street to the south and southeast. Site access would not change as part of the proposed project. Additionally, the proposed project is not anticipated to require road closures during project construction as all proposed improvements would occur within the project boundary.

4.17.3 Conclusion
Overall, the project is consistent with the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe transportation impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.18 Tribal Cultural Resources

4.18.1 GPU EIR Findings
The City consulted with applicable Native American tribes in accordance with Senate Bill (SB) 18 and Assembly Bill (AB) 52. Given that tribal cultural resources are site-specific in nature. Future development allowed under the General Plan Update could potentially impact and cause significant adverse impacts to tribal cultural resources. Thus, Mitigation Measures CUL-4 through CUL-7 would reduce such impacts to less than significant levels. Specifically, to reduce impacts to archaeological resources and prior to ground-disturbing activities, Mitigation Measure CUL-4 requires an Archaeological Resources Assessment be conducted under the supervision of an archaeologist that meets the Secretary of the Interior’s Professionally Qualified Standards in either prehistoric or historic archaeology. If potentially significant archaeological resources are identified and impacts cannot be avoided, Mitigation Measure CUL-5 requires a Phase II Testing and Evaluation investigation be performed by an archaeologist meeting the Secretary of the Interior’s Standards to determine the significance of the resource(s). Per Mitigation Measure CUL6, if the Archaeological Resources Assessment does not identify archaeological resources but indicates the project area to be highly sensitive for archeological resources, a qualified archaeologist and a Native American monitor culturally affiliated with the project area must monitor all ground-disturbing activities in the areas of high archaeological sensitivity. In the event that archaeological resources (artifacts or features) are exposed during ground-disturbing activities, construction activities in the immediate vicinity of the discovery must halt while the resources are evaluated for significance by a qualified archaeologist. Pursuant to Mitigation Measure CUL-7, if the Archaeological Resources Assessment does not identify potentially significant archaeological resources but the site has moderate sensitivity for archaeological resources, an archaeologist meeting the Secretary’s Standards must be retained on-call. The archaeologist must inform all construction personnel prior to construction activities about the proper procedures in the event of an archaeological discovery. Overall, the GPU EIR determined that implementation of Mitigation Measures CUL-4 through CUL-7 would reduce tribal cultural resources impacts to less than significant levels.

4.18.2 Project Analysis
Although the project would redevelop the shared surface parking lot in the southern portion of the site into an outdoor community garden, play field, and play yard, the proposed project would not require extensive excavation that could uncover previously undiscovered tribal cultural resources.

Typical excavation depth would be a maximum of four feet for the majority of the site with the deepest excavation of approximately eight feet for an underground infiltration chamber related to stormwater improvements. No new or substantially more severe impacts would occur compared to the determinations of the GPU EIR, and no new mitigation measures are required.

4.18.3 Conclusion
Overall, the project is consistent with the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project-specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe tribal cultural resource impacts than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

4.19 Utilities and Service Systems

4.19.1 GPU EIR Findings
The GPU EIR concluded that increased sewer flow from buildout of the General Plan Update would require pipe upsizing to meet the demands of new residential and commercial uses; however, the Orange County Sanitation District Master Plan accounts for trunk line improvements and the Orange County Sanitation District (OCSD), in general, has a functioning and effective process in place to ensure the regional sewer infrastructure is able to support future developments in the City. Further, OCSD confirmed that wastewater generated by buildout of the General Plan Update would be adequately treated by Treatment Plant No. 1. The GPU EIR also concluded sufficient Orange County Water District water supplies and Orange County Public Works stormwater drainage facilities would be available to serve the full General Plan Update buildout from existing entitlements and resources, and new or expanded entitlements would not be required beyond those improvements already planned for the City.

4.19.2 Project Analysis
Based on wastewater generation rates for commercial uses in the West Santa Ana Focus Area, contained within Volume III, Appendix H-a, of the GPU EIR, the proposed project would generate approximately 2,036 gallons of wastewater per day.30 The proposed project would connect to existing wastewater infrastructure, which would have the capacity to serve the project demand in addition to existing service commitments and would not require the expansion of existing facilities.

Compliance with RR U-2 would ensure that OCSD connection fees are paid in accordance with Ordinance No. OCSD-40. Additionally, as discussed above, runoff from the proposed project is currently collected by stormwater drainage facilities in the surrounding roadway. The proposed project would implement BMPs contained in the WQMP to capture and infiltrate stormwater runoff. 30 Based on a rate of 2,262 gallons of wastewater per day per acre for a 0.9-acre site. The GPU EIR separated land uses into either residential or commercial in order to determine average wastewater generation. While it is acknowledged that the proposed project would involve office use, commercial rates were deemed most appropriate in order to compare the proposed project to the analysis contained within the GPU EIR.

Any runoff leaving the project site would continue to drain to the existing drain inlets in the project area, and the proposed project would not require or result in the construction of new or expanded storm water drainage facilities. Based on water demand rates for commercial uses, contained within Volume III, Appendix H-b, of the GPU EIR, the proposed project would require approximately 2,250 gallons of water per day, which would be met by the City’s supplies.31 However, compliance with RR U-5 would ensure that the project is designed pursuant to the water conservation and efficiency requirements of the Municipal Code, and RR U-6 would ensure water connection fees are paid. Therefore, consistent with the General Plan Update, impacts related to water supplies, wastewater treatment, and storm water drainage from the proposed project would be less than significant.

The proposed project would generate a nominal amount of solid waste during construction activities. However, the proposed project would comply with the CALGreen Building Code Standards, which requires that at least 65 percent of nonhazardous construction and demolition waste generated during most new construction be recycled and/or salvaged for reuse. During operations, the proposed project would generate approximately 34.8 pounds of solid waste per day, typical of office uses.32,33 According to the GPU EIR, solid waste generated in the City is transferred to Orange County solid waste landfill system which has ample capacity to accommodate increased volumes of waste from the City through 2053. Furthermore, the proposed project would be required to comply with the requirements of AB 341, which mandates recycling for commercial land uses, and AB 1826, which requires that any organic waste generated in amounts over a certain threshold would be recycled. Therefore, the proposed project would not generate solid waste in excess of State or local standards or of the future capacity of local infrastructure, and would comply with all applicable federal, State, and local solid waste regulations. Consistent with the General Plan Update, impacts would be less than significant.

The site is currently served by SCE and Southern California Gas Company (SoCalGas). Project impacts with regards to electricity and natural gas services would be nominal given that operations of the proposed office would utilize minimal electricity and natural gas. As summarized under Section 4.6, Energy, the project would not result in substantial energy consumption, upon compliance with existing regulatory requirements, including the 2022 Title 24 Building Energy Efficiency Standards and 2012 Appliance Efficiency Regulations pursuant to RR E-3 and E-4.

Additionally, the project would be required to pay connection and ongoing user fees to SCE and SoCalGas to offset project impacts on existing dry utility services and resources. Thus, impacts with regards to dry utilities would be less than significant.

4.19.3 Conclusion
As such, the project is consistent with the General Plan Update. With implementation of RR U-2, U-5, U-6, HYD-4, and HYD-5 identified in the GPU EIR, the proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to utilities and service systems than anticipated by the GPU EIR.

4.20 Wildfire

4.20.1 GPU EIR Findings
The GPU EIR concludes that buildout of the General Plan Update would not substantially impair an adopted emergency response plan or emergency evacuation plan, exacerbate wildfire risks thereby creating elevated particulate concentration exposure to people, nor would it expose people or structures to significant risks. The General Plan Update would require the installation and maintenance of associated infrastructure in areas that are undeveloped or vacant which could exacerbate fire risk.

4.20.2 Project Analysis
The CEQA Guidelines require analysis of wildfire risk in State responsibility areas (SRAs) and/or lands classified as very high fire hazard severity zones. As stated in the GPU EIR, the nearest fire hazard severity zone (FHSZ) in an SRA to the City of Santa Ana is a high FHSZ about four miles east along the western edge of Loma Ridge. The nearest FHSZ in a local responsibility area (LRA) is about 3.8 miles at the southern tip of the Peters Canyon Regional Park. Therefore, the project site is not in or near SRAs or lands classified as very high FHSZs. Additionally, no area in the City is a wildland-urban interface. As such, no impact related to wildfire risk would occur due to development of the proposed project.

4.20.3 Conclusion
As such, the project is consistent with the General Plan Update. The proposed project would not have any specific effects which are peculiar to the project or the site. There are no project specific impacts or potentially significant off-site or cumulative impacts the GPU EIR failed to analyze, and there are no new significant or substantially more severe impacts to wildfire than anticipated by the GPU EIR.

Applicable GPU EIR Regulatory Requirements/Mitigation Measures: No GPU EIR regulatory requirements or mitigation measures apply.

5. Findings
As discussed in Section 3.0, the City of Santa Ana intends to pursue a CEQA exemption for the proposed project pursuant to CEQA Guidelines Section 15183. As stated in CEQA Guidelines Section 15183(d), the exemption requires a project to meet the following conditions:

1. The project is consistent with:
a. A community plan adopted as part of a general plan,
b. A zoning action which zoned or designated the parcel on which the project would be located to accommodate a particular density of development, or c. A general plan of a local agency, and

2. An EIR was certified by the lead agency for the zoning action, the community plan, or the general plan.

The General Plan Update and GPU EIR were adopted and certified by the Santa Ana City Council in 2022. The project site is located within the General Plan Update West Santa Ana Boulevard Focus Area. This portion of the City was historically a more industrial area; the General Plan Update intends to transition the area from a group of auto-oriented neighborhoods, businesses, and institutions into a series of transit-oriented neighborhoods that support and benefit from future streetcar stops. Additionally, the industrial portion of the focus area (where the project site is located) is envisioned and designated Industrial/Flex (FLEX) to promote new opportunities, including new clean industrial/manufacturing, maker-type spaces, and other uses that are more compatible with the surrounding residential areas than traditional industrial uses. The project site has a land use designation of Industrial/Flex-Low (FLEX-1.5), which is intended for office/industrial flex spaces, small-scale research and development, clean manufacturing, and live-work uses. The proposed project would redevelop a former automotive repair building into a school district office, which is a permitted use under the FLEX-1.5 designation and considered in the analysis of the GPU EIR. Additionally, the General Plan Update encourages adaptive reuse of existing industrial buildings within this focus area, which would be achieved with implementation of the project. As such, the GPU EIR adequately anticipated and analyzed the impacts of this project, identified applicable mitigation measures necessary to reduce impacts of the project, and the project implements the applicable mitigation measures. The project, therefore, qualifies for an exemption from additional environmental review as set forth in CEQA Guidelines Section 15183.

Overall, the project qualifies for the exemption because the following findings can be made:
a) The project is consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified.

Based on General Plan Update Land Use Element Figure LU-1, Land Use Map, the project site is designated Industrial/Flex-Low (FLEX-1.5). The FLEX-1.5 designation allows a maximum 1.5 FAR and/or 30 dwelling per acre, with a maximum building height of three stories.

The proposed project would renovate the approximately 5,837-square foot former automotive repair building as the Vista Charter Public Schools district office. The project site is approximately

0.9-acre. Thus, the project would result in a 0.15 FAR. Additionally, the building would maintain its existing building height of approximately 19.3 feet. Thus, the proposed project would be consistent with the site’s FLEX-1.5 designation development density established by the General City Council 26 – 407 1/16/2024
Vista Charter Public Schools District Office and Outdoor Space Project CEQA Exemption 15183
December 2023 Page 59
Plan Update. Additionally, the project would be consistent with applicable General Plan Update Land Use Element policies as detailed in Table 5. Overall, the project would be consistent with Criterion A.
b) There are no project specific effects which are peculiar to the project or its site.

The project site is located within the Fairview Business Park in an industrial area of Santa Ana.

The Fairview Business Park is currently developed with institutional (Vista Heritage Global Academy and Templo Calvario Church), industrial, and office uses. As stated, the site’s FLEX1.5 land use designation is intended to provide context-appropriate development in areas with existing industrial uses. The proposed Vista Charter Public Schools district office and outdoor open space areas would complement and serve the existing Vista Heritage Global Academy located adjacent to the site’s southern boundary. Additionally, upon approval of the required Zone Change and Zoning Ordinance Amendment, project development would be required to comply with applicable standards for the SD-82 zone, which is consistent with the standards for Light Industrial uses in Municipal Code Sections 41-473 through 41-481. As such, the proposed project would not result in effects which are peculiar to the project or its site and the project would be consistent with Criterion B.
c) There are no project specific impacts which the prior EIR failed to analyze as significant effects.

The GPU EIR concluded that buildout of the General Plan Update would result in a total of 115,053 residential units and 72,967,816 square feet of non-residential development by 2045.

The proposed project, which is consistent with the General Plan Update, involves renovating an existing 5,837-square foot building and developing outdoor open space areas on an approximately 0.9-acre site. The project would meet the development density requirement for the FLEX-1.5 designation and thus, was considered in the planned development of the General Plan Update and would have similar or lesser significant impacts than analyzed in the GPU EIR. As discussed in Section 4.0, there are no project specific impacts which the GPU EIR failed to analyze as significant effects. The proposed project is consistent with Criterion C. d) There are no potentially significant off-site and/or cumulative impacts which the prior EIR failed to evaluate.

As stated, buildout of the proposed project is consistent with the General Plan Update and thus, was considered in the GPU EIR analysis. No off-site improvements are proposed in the project area and the size and nature of the project would not result in cumulatively considerable environmental impacts. Overall, there are no potentially significant off-site and/or cumulative impacts which the GPU EIR failed to evaluate. The project is consistent with Criterion D. e) There is no substantial new information which results in more severe impacts than anticipated by the prior EIR.

As discussed in Section 4.0, the proposed project would result in similar and/or lesser impacts than the GPU EIR. There is no substantial new information which result in more severe impacts than anticipated by the GPU EIR. Therefore, the proposed project is consistent with Criterion E.

As shown, the proposed project is consistent with Criteria A through E under CEQA Guidelines Section 15183. As such, the proposed project qualifies for the CEQA exemption.

6. Climate Risk Detailed Report

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. City Council 26 – 469 1/16/2024 Vista Charter School Expansion Detailed Report, 7/26/2023 58 / 63
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.
