3 1.0 INTRODUCTION
The purpose of this Initial Study/Mitigated Negative Declaration (IS/MND) is to identify any potential environmental impacts from developing the proposed 840 The City Drive Apartments project (proposed project) in the City of Orange, California. Pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15367, the City of Orange has discretionary authority over the proposed project and is the Lead Agency in the preparation of this IS/MND and any additional environmental documentation required for the proposed project. The intended use of this document is to determine the level of environmental analysis required to adequately analyze the proposed project pursuant to the requirements of CEQA and to provide the basis for input from public agencies, organizations, and interested members of the public.
The remainder of this section provides a brief description of the project location and the primary project characteristics. This IS/MND also includes an environmental checklist that provides an overview of the potential impacts that may result from project implementation, elaborates on the information contained in the environmental checklist, and provides justification for each environmental checklist response, as well as a List of Preparers.
2.0 EXISTING SETTING
Regional Setting
The City of Orange is in the north central part of Orange County. The City of Orange is bordered by the City of Anaheim to the north and northwest, the City of Garden Grove to the west, and the cities of Santa Ana and Tustin and portions of unincorporated County of Orange to the south and east.
Existing Site Conditions
The project site, located at 840 The City Drive South, includes three parcels (Assessor’s Parcel Numbers [APNs) 231-261-13 [1.12 acres], 231-361-16 [0.95 acres], and 231-261-17 [3.77 acres]) totaling 5.86 acres. The site is part of a larger 15.1-acre multi-building office complex located at the northwest corner of the intersection of Garden Grove Boulevard and The City Drive South, in the southwest portion of the City of Orange (Figure 1). It is noted that surrounding existing uses are not part of the proposed project and are under separate ownership. The mixed-use component of the proposed project would be constructed on 5.86 acres.
The 5.86-acre site is currently developed with an approximately 12,923-square-foot, single-story, multi-tenant commercial building that was constructed around 1989.1 Existing tenants include several restaurants, a beauty salon, and a private fitness center for adjacent office uses. 2 The project
site is also currently developed with an asphalt-paved parking lot and landscaping. The larger 15.1- acre site is developed with an existing multi-building office complex, consisting of two 4-story office buildings and one 8-story office building totaling 387,200 square feet of existing office 1 Leighton and Associates, Inc. 2019. Phase I ESA, 840 The City Drive South. 2 Ibid.
4 space, surface and structured parking, landscaping, and related site improvements. Directly north of the project site, adjacent to the multi-building office complex, is an existing 3-story hotel that is not part of the proposed project or larger 15.1-acre office complex site (Figure 3).
The project site is approximately 115 feet above mean sea level and is relatively flat. The Santa Ana River is located approximately 430 feet east of the project site. Stormwater from the project site sheet flows over paved and unpaved surfaces to the storm drain within Garden Grove Boulevard.3
Access
The site is 0.75 mile southwest of Interstate 5 (I-5) and 0.25 mile south of State Route 22 (SR 22).
Regional access to the site is provided via I-5 and The City Drive South.
Public Transit
The Orange County Transportation Authority (OCTA) currently provides public transit to the project site. The project site is located 125 feet north of a bus stop for Bus Route 56, Garden Grove to Orange, located at the southwest corner of the intersection of Garden Grove Boulevard and The City Drive South. Additionally, a stop for Bus Route 57, Brea to Newport Beach, is located 110 feet east of the project site. Both bus stops are accessible from the site via crosswalks on Garden Grove Boulevard and The City Drive South. A bus stop for Bus Routes 47 and 47A, Fullerton to Balboa, are located at the intersection of South Lewis Street and Garden Grove Boulevard, 0.35 mile west of the project site.
Surrounding Land Uses
• To the north of the project site is the larger multi-building office complex, surface parking lot, and 3-story hotel designated Urban Mixed-Use 30-60 dwelling units per acre (du/acre) and zoned Urban Mixed-Use. Also, to the north, beyond the office complex and hotel are residential uses and West Park Central Avenue designated Low Medium Density Residential 6-15 du/acre (LMDR) and zoned R-2-6 (Residential Duplex 6,000 square feet).
• To the south, the site is bounded by Garden Grove Boulevard. Further south is the City of Santa Ana and residential uses designated by the City of Santa Ana as Low Density Residential (LR-7)4
and zoned R1 (Single-family Residence).5
• To the west is a multi-building office complex and surface parking lot designated Urban Mixed-Use 30-60 du/acre and zoned Urban Mixed-Use. Further west are residential uses and South Park Vine Street designated Medium Density Residential 15-24 du/acre (MDR) and zoned R-2-6 and R-4 (Residential Maximum Multi-Family).. 3 Bureau Veritas North America, Inc. 2012.

Accessed August 18, 2022. 5 • To the east, the site is bound by The City Drive South. Further east is a 4-story office building and surface parking lot designated Urban Mixed-Use (UMIX) and zoned Urban Mixed-Use (UMU) and R-O (Recreation Open Space) along the Santa Ana River.
According to aerial photographs, in 1947 the site was vacant but agricultural uses occurred to the west of the project site. In 1953, Garden Grove Boulevard was developed to the south, additional orchards and a few residences were located across Garden Grove Boulevard. 6 I-5 was built by
1965.7 In 1977, the site was developed with two small office buildings and a parking lot. Between 1989 and 2012, the present-day 15.10-acre multi-building office complex was constructed, including the existing commercial development. The project site and surrounding properties have been in their current configuration since 2016.8
General Plan
The project site is currently designated as Urban Mixed-Use 30-60 dwelling units per acre (UMIX) in the General Plan Land Use Map (Figure 4). The UMIX designation allows a development density of 30-60 dwelling units per acre and floor area ratio (FAR) of 1.5- 3.0. The UMIX designation is intended for urban, high-intensity, regionally oriented activity centers that define the character of surrounding areas and serve as gateways to the City. Commercial retail uses are intended to be the primary use on the ground floor. The project site is within the West Chapman Avenue/Uptown Orange land use focus area, within the High-Intensity Retail, Office, and Housing Development designation. Land use focus areas represent locations in the City where future land use change may occur. The West Chapman Avenue/Uptown Orange focus area consists of mostly commercial and industrial properties located west of SR-57, as well as commercial areas located along Anita Drive, just east of the Santa Ana River.9
Zoning
The project site is zoned Urban Mixed Use (UMU) as shown in Figure 5. The intent of the UMU Zone is to allow a variety of land uses. This designation provides for integrated commercial, retail, high-rise office, housing, civic uses, convenient high-frequency transit access, innovative housing options, and pedestrian-oriented design. This zone implements the Urban Mixed-Use land designation in the General Plan. According to the General Plan Land Use Element, Urban MixedUse zoned areas are designated as 30-60 dwelling units per acre. 6 Leighton and Associates, Inc. 2019.

Project Objectives
To provide a well-designed development that is economically feasible and complementary to surrounding land uses.
Help give a destination for the nearby office workers with its shared amenities, but also acting as an important gateway to the southernmost entrance of The City Drive.
Create a nice walking experience at the street, encourage street life, and connect into the existing office park through enlarged storefronts with canopies, street trees, enhanced paving, and parallel parking.
Create an aesthetically pleasing project façade by creating a break on the east side of the building with the elevated pool courtyard and amenity space. The pool would have unobstructed views of the mountains to the east.
To create an urban building that engages the street by replacing surface parking and introducing a secondary parking structure serving the office buildings.
The proposed project is designed to encourage energetic urban street life, provide large windows for natural light, provide safe and well-designed units with views, exciting amenities, and a timeless building design.
Project Overview
The project proposes the development of a mixed-use residential and commercial project on a
5.86-acre site, located on the southeastern corner of a larger existing 15.10-acre multi-building office complex at the northwest corner of Garden Grove Boulevard and The City Drive South.
The proposed project includes the demolition of an existing 12,923-square-foot single-story retail building and associated 172 stall surface parking lot in order to construct a 6-story, 225-unit multifamily residential apartment complex with 9,000 square feet of ground level retail/restaurant space, 3,628-square-foot private fitness center, and 6,635-square-foot lobby, leasing, and lounge area.
The proposed project also includes construction of a 3-story basement level parking structure beneath the footprint of the mixed-use building to serve the residential and retail uses, and the replacement of 89 surface parking lot to construct a stand-alone, 2-story open parking structure with 143 parking spaces for use by the adjacent multi-building office complex, to be located west of the mixed-use building and parallel to the south property line along Garden Grove Boulevard.
The proposed project would be required to apply for a City of Orange Lot Line Adjustment approval pursuant to the Orange Municipal Code (Municipal Code) Chapter 16.32.10The Lot Line 10 City of Orange. 20202. Code of Ordinances, Chapter 16.32 - Lot Line Adjustments. Website:
https://library.qcode.us/lib/orange_ca/pub/municipal_code/item/title_16-chapter_16_32. Accessed August 18, 2022. 7 Adjustment would expand the property boundary along the northern boundary of the project site and would slightly adjust the project site along the southwestern boundary. The Lot Line Adjustment would modify the boundaries between parcels 231-261-13 and 231-261-17 to accommodate the construction of the new mixed-use building and for property ownership purposes.
Project density is factored utilizing the three parcels [231-261-13 (1.92 acres), 231-261-16 (0.95 acre), and 231-261-17 (2.99 acres)] totaling 5.86-acres. Thus, 225 dwelling units on 5.86 acres is approximately 38.4 dwelling units per acre. The proposed multi-family residential gross area is 249,664 square feet, ground level commercial is 9,000 square feet, amenity uses total 6,635 square feet, the fitness center is 3,628 square feet, and the existing office building at 790 The City Drive is 98,800 square feet resulting in a total of 367,727 square feet. Thus, the resulting FAR is 1.44.
As shown in Figure 7, the proposed project would include the demolition of the existing retail building located on the Parcel 6 at the southeast corner of the multi-building office complex and construction of a 7-story, 225-unit multi-family residential complex with up to 9,000 square feet of ground level retail space, a 3,628-square-foot private fitness center, and a 6,635-square-foot lobby, leasing, and lounge area. The residential complex would include a centrally located pool and courtyard. The residential units would be located both on the ground floor and on the upper floors of the development. Additionally, the proposed project would include a 3-story basement level parking structure beneath the footprint of the residential complex. There would be a single-story up to 9,000- square-foot retail and restaurant facility on the northern portion of the project site.

9 Architecture and Design Features
The applicant, Streetlights Residential, prides itself on providing the highest quality architectural materials and building design. The proposed building is designed to interact with its context. The warm masonry base, stucco midsection, and painted shiplap crown is meant to complement the existing office complex and surrounding neighborhood (Figure 8a and 8b).
The proposed project helps give a destination for the nearby office workers with its shared amenities, and it also acts as an important gateway to the southernmost entrance of The City Drive.
To celebrate this entry, the leasing and amenity portions of the building are oriented facing this important intersection. This allows the light and activity happening within the building to show through the double height space and enlarged storefront windows to help activate the street.
Double height retail space is included and a shared fitness component sitting at the main ceremonial entrance to the office park located just north Garden Grove Boulevard on The City Drive South. This taller space emulates what is happening to the southern amenity space. There would be enlarged storefronts with canopies, street trees, enhanced paving, and parallel parking all geared to create a nice walking experience at the street, encourage street life, and connect into the existing office park.
All the multi-family units would be elevated on top of a 5-foot parking podium. Raising the living units would allow the lowest units to have an unobstructed view over the heavily trafficked road, increasing the safety, desirability, and livability of these units. Where feasible, elevated gated patios are introduced with access to the sidewalk driving the desire for an energetic engaged street where possible.
The pool courtyard is elevated atop of the 5-foot parking podium. The pool is flanked by the amenity space and units but is open on the east side of the building. Creating this break in the façade allows the pool to have unobstructed views of the mountains to the east. Also, this allows a visual break in the perceived length of the building along The City Drive South, creating the appearance of a much smaller and more intimate building.
To accommodate the increase in density and desire to create an urban building that engages the street, a secondary parking structure is proposed to replace the surface parking removed serving the office building. The parking structure was designed to be of low visual impact and help screen the office building at 790 The City Drive South from the noise of Garden Grove Boulevard. It would be 2-stories tall and clad in brick to match the exiting parking structure and offices on-site.
The existing large trees would remain in place and tall shrubs would be planted to help screen the parking structure on the façade facing Garden Grove Boulevard.
Project Components
Residential Component
The proposed project includes the construction of 225 residential units spread across six levels.
There would be 25 residential units on Level 1. Levels 2 and 5 would have 46 residential units. 10 Levels 3 and 4 would have 47 residential units per floor. Level 6 would include 14 residential units.
Apartment sizes would vary from 558 to 1,533 square feet, with 36 studio apartments (558 to 680 square feet in size), 102 1-bedroom apartments (603 to 868 square feet in size), and 87 2-bedroom apartments (1,039 to 1,5333 square feet in size) (Figure 7).
The residential component of the proposed project would include two private outdoor courtyards for residents, with patio furniture including lounge chairs and sofas, tables, chairs and umbrellas. seating to accommodate up to 12 people in the smaller courtyard and up to 60 people in the pool courtyard, The outdoor courtyards will also include firepits, raised planters, a pool and spa, overhead shade structure, outdoor kitchen, television, and barbecue counters. A private fitness center for residents is also proposed.
The proposed project would include a vehicle speed ramp leading from the ground level to the subterranean parking. The leasing center, lobby, and lounge area would be set back from the intersection with a large public plaza with lush planting, building awnings, and building signage activating the intersection of Garden Grove Boulevard and The City Drive.
Retail Component
The ground floor of the building would include up to 9,000 square feet of retail/restaurant space on the north side of the building.

The primary access to the project site would be provided by an existing internal divided two-way roadway that connects to The City Drive South on the north side of the site. Secondary access to the site would be provided by an existing driveway along Garden Grove Boulevard, located approximately 189 feet west of the intersection of Garden Grove Boulevard and The City Drive from the south.
Parking
The proposed project would provide 13 surface parking spaces and construct a three-level subterranean parking garage that includes 434 parking spaces for residents, guests, and retail/restaurant customers.
The Municipal Code would require 390 parking spaces for the residential component of the proposed project.
11 Municipal Code Section 17.34.060 identifies the parking requirement for the project. Table 17.34.060A requires that multi-family residential for a development of 51 units or 11 City of Orange. 2022. Code of Ordinances, Chapter 17.34 – Off-street Parking and Loading. Website:
https://library.qcode.us/lib/orange_ca/pub/municipal_code/item/title_17-chapter_17_34. Accessed August 18, 2022. 11 more provide: 1.2 spaces/studio unit; 1.7 spaces/1-bedroom unit; 2.0 spaces/2-bedroom unit; 2.4 spaces/3-bedroom unit; and 0.2 spaces/unit for guest parking.
There are no 3-bedroom units proposed, so the proposed 225-unit project would require 435.6 parking spaces for the multi-family component. The proposed project would provide 434 total parking spaces for retail and residential uses and one space reserved for USPS parking for a total addition of 435 spaces. The applicant is unable to achieve the 481 vehicular spaces required by code and is formally requesting a 10 percent Parking Adjustment. A 10 percent code reduction would bring the required parking count to 433 stalls, or one stall fewer than currently provided.
Municipal Code Table 3 illustrates the parking requirement for the retail and office components of the site. For general retail with less than 25,000 square feet of gross floor area (GFA), the code requires five spaces/1,000 square feet of GFA. If restaurant space occupies more than 10 percent of the total GFA or if an individual restaurant contains more than 1,000 square feet, additional parking shall be provided calculated at the restaurant rate. The restaurant rate is 10 spaces per 1,000 square feet of GFA for the first 4,000 square feet, then 14.2 spaces each 1,000 square feet of GFA above 4,000 square feet. For the project’s proposed 9,000 square feet of general retail, the parking requirement is 45 (9,000 x 0.005). Adding these 45 retail spaces to the multi-family requirement, the proposed development would require the addition of 481 spaces as shown in Table 3 below.

Total City Code Required Parking 480.6
10 percent Reduction Applied 434
Additional Project Features
In addition to the construction of the mixed-use residential and commercial building, the applicant proposes to construct a stand-alone, 2-story open parking structure near the southern area of the existing 15.10-acre office complex along Garden Grove Boulevard. The parking structure would replace the existing surface parking lot and spaces that would be removed to accommodate the proposed mixed-use building (Figure 7).
The proposed parking structure would remove 89 surface parking spaces from the existing 790 The City Drive office building. The 89 spaces that would be removed would be replaced with 143 12 parking spaces. The proposed office parking for the existing 790 The City Drive office building totals an average ratio of 3.40 parking spaces per 1,000 GFA. This parking structure would be for the existing office uses only and is not intended to accommodate the proposed mixed-use project.
Landscaping and Lighting
A comprehensive landscape plan that includes a variety of new trees, shrubs, and groundcover would be implemented for the proposed project. Landscaping would be provided in the two private open courtyards, along the building perimeter, and along street frontages. There would be 10-foot building setbacks along The City Drive South and Garden Grove Boulevard. To help screen the parking structure on the façade facing Garden Grove Boulevard, the existing large trees would remain in place and tall shrubs would be planted. The total landscape square footage would be 10,052 square feet. The total hardscape area would be 19,121 square feet. Additionally, there would be 10-foot building setbacks along The City Drive South and Garden Grove Boulevard.
The plant species proposed for the groundcover of the perimeter area would consist of coyote brush (Baccharis P.S ‘Pigeon Point’), green carpet natal plum (Carissa M. ‘Green Carpet), trailing myoporum (Myoporum parvifolium ‘Pink’), white flower carpet rose (Rosa ‘White Flower Carpet’), and blue chalk stick (Senecio M. ‘Blue Chalk Sticks’).
The plant species proposed for the groundcover of the courtyards would consist of green carpet natal plum, trailing myoporum, and white flower carpet rose, and star jasmine (Trachelospermum jasminoides).
Pedestrian walkways linking residential units to retail area would be paved with natural gray concrete sidewalks. The plaza entry as well as retail frontage would be enhanced with paving, such as colored concrete or pavers. Benches would be provided along Garden Grove Boulevard near the plaza entry, as well as Date Palm trees along the street frontage. Formal Golden Barrel Cactus planting would be located at the corner of Garden Grove Boulevard and The City Drive in front of oversized letters with the project name as monument sign/art.
The courtyard areas would be colored with concrete finishing and complemented with raised concrete masonry unit (CMU) planters with smooth stucco finish. CMU planters with smooth stucco finish are also proposed in the pool area. A 6-foot glass fence would surround the perimeter of the pool area. The pool deck would be enhanced with artificial turf and colored concrete or pavers. A portion of the pool area would provide shade with an overhead trellis. Another courtyard area would be located adjacent to the pool area with a wall-mounted television.
Lighting for the new residential development and associated parking areas would consist of building-mounted light fixtures, lighting for pedestrian walkways surrounding the structure, ground-mounted decorative lighting for landscape and architectural features, interior area lighting, and decorative lighting in the patio areas. Festoon lights would be provided above residential courtyard areas. Step lights would be provided along public outdoor stairways. 13 All lighting and permanent fixtures would be Underwriters Laboratories (UL) tested and approved.
The design of the lighting would be done so that main entrances, focal points, and gathering places are illuminated to enhance each space. Fixtures located on the buildings and within the landscape are intended to illuminate emergency egress pathways to meet all local codes and requirements.
Appropriate wattages and accessories, such as cut-off shields, would be utilized.
Grading and Construction
For the purposes of this analysis, project construction is assumed to begin December 31, 2022, and to be completed by June 30, 2024, for a total of approximately 599 working days. Construction would include the demolition of the existing retail building and existing parking areas, site preparation, mass grading, construction of the building and parking structure, asphalt paving of new parking areas, and architectural coating of the inside and outside of the buildings.
Utilities and Service Systems
The following utility providers serve the project area and would be available to serve the proposed project:
• Electricity–Southern California Edison (SCE)
• Natural gas–Southern California Gas Company (SoCalGas) • Telephone and fiber-optic lines–AT&T
• Cable service–Charter Communications
• Solid waste–CR&R Waste and Recycling Services.
12 Other Public Agencies Whose Approval is Required (Responsible or Trustee Agencies):
• Southern California Edison
• Regional Water Quality Control Board (RWQCB)
• South Coast Air Quality Management District (SCAQMD)
12 The City of Orange owns and maintains the existing public water lines and the sewage system related to the project site.

DETERMINATION. On the basis of this initial evaluation:
1. I find that the project could not have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared.
2. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.
3. I find the proposed project may have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.
4. I find that the proposed project may have a “potentially significant impact” or “potentially significant unless mitigated impact” on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed.
34 5. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or Negative Declaration pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.
Project Planner Date
Planning Manager Date
EVALUATION OF ENVIRONMENTAL IMPACTS:
1. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question.
A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).
2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.
3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant impact with mitigation, or less than significant. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect may be significant. If there are one or more “Potentially Significant Impact” entries when the determination is made, an EIR is required.
4. “Negative Declaration: Less than Significant Impact with Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than Significant Impact.” The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from earlier analyses may be cross-referenced, as discussed below).
5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or Negative Declaration. Section 15063 (c)(3)(D). In this case, a brief discussion should identity the following:
a. Earlier Analysis Used. Identify and state where they are available for review. b. Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis.
c. Mitigation Measures. For effects that are “Less than Significant Impact with Mitigation Measures Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 35 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated.
7. Supporting Information Sources: A source list should be attached, and other sources used, or individuals contacted should be cited in the discussion.
8. This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project’s environmental effects in whatever format is selected.
9. The explanation of each issue should identify:
a. the significance criteria or threshold, if any, used to evaluate each question; and b. the mitigation measure identified, if any, to reduce the impact to less than significance.

If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
(d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?
Impact Analysis
Except as provided in Public Resources Code Section 21099, would the project:
(a) Have a substantial adverse effect on a scenic vista? A significant impact would occur if a project were to substantially block public views of a scenic vista. The General Plan defines a scenic vista as a viewpoint that provides expansive views of a highly valued landscape for the benefit of the general public. Portions of the City of Orange are characterized by scenic vistas including undeveloped hillsides, ridgelines, and open space areas that provide a unifying visual backdrop to the urban environment. These viewsheds are identified in Figure 5.1-1 of the General Plan Environmental Impact Report (EIR).13 The project site is located in an urbanized area of the City. The uses surrounding the project site include a mix of commercial, residential, office, and medical uses that do not provide any significant visual resources or scenic vistas. General Plan Figure NR-1, Open Space Resources, does not identify any open spaces located on or in the surrounding or immediate vicinity of the project site.
According to General Plan Figure NR-4, viewscape corridors within the City of Orange are located primarily along Santiago Canyon Road, East Chapman Avenue, and Newport Boulevard.14 The nearest designated viewscape corridor is along Newport Boulevard, 5.97 miles northeast of the project site. Because of the distance and intervening development, this viewscape is not visible from the project site; therefore, the proposed project would not affect this scenic resource. 13 City of Orange. March 2010. City of Orange General Plan, Program Environmental Impact Report. Website:
https://www.cityoforange.org/home/showpublisheddocument/240/637698173340500000. Accessed August 18, 2022. 14 City of Orange. 2010. General Plan, Figure NR-4 Viewscape Corridors.
Websitehttps://www.cityoforange.org/home/showpublisheddocument/210/637698172559270000. Accessed August 18, 2022. 38 Additionally, the General Plan indicates that the City has 7,400 acres of open space, which includes parks, ridgelines, and areas designated as Open Space. The Open Space designation describes the various open space resources within the City. According to the General Plan, the nearest open space is located along the Santa Ana River corridor, approximately 330 feet east of the project site.15 Most of the Open Space areas in the City are located in the eastern portion of the City more than 5 miles east of the project site and are not visible from the project site. Additionally, the designated Open Space areas along the Santa Ana River corridor would not be adversely impacted by the proposed project because the proposed project would not substantially block scenic views of the Santa Ana River corridor. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway? A significant impact would occur if scenic resources would be damaged or removed by a project within a designated scenic highway. According to California Department of Transportation (Caltrans) Scenic Highway Mapping System, the nearest State-designated scenic highway is SR91 at its terminus with SR-55, located 6.1 miles northeast of the project site.16 The project site is not visible from this State Scenic Highway, which precludes the possibility of the project damaging scenic resources within a State Scenic Highway. Additionally, the project site is currently developed with a four-story multi-tenant office building and parking lot that does not contain scenic resources such as trees, rock outcroppings, or historic buildings. Therefore, no impacts would occur.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
A significant impact may occur if a project were to introduce incompatible visual elements on the project site or visual elements that would be incompatible with the character of the area surrounding the project site, or which would conflict with applicable zoning and other regulations 15 City of Orange. 2010.

The proposed project includes the demolition of an existing single-story retail building and associated surface parking lot in order to construct a 6-story, 225-unit multifamily residential apartment complex with ground level retail/restaurant space, private fitness center, and lobby, leasing, and lounge area. The proposed project also includes construction of a 3-story basement level parking structure beneath the footprint of the mixed-use building, and construction of a stand-alone, 2-story open parking structure for use by the adjacent multi-building office complex, to be located west of the mixed-use building and parallel to the south property line along Garden Grove Boulevard in an area designated UMIX and zoned UMU.
The project site is located in an urbanized area of the City. The project site is currently developed with an existing commercial 4-story office building and parking lot and is on the southeast corner of a multi-building office complex. The proposed project would be consistent with the existing urban character of the site, which is an office complex consisting of several multi-story office buildings and parking lots, surrounded by commercial, retail, residential, and open space uses. The building height and appearance would be consistent with the other buildings within the office complex. Additionally, as shown in Figure 9a through Figure 9c, the proposed project’s landscaping plan and improvements would increase on-site landscaping and pervious surfaces which would ensure that the visual quality of the project site is maintained. As shown in Figure 9a through Figure 9c, the proposed project would include trees and groundcover, a widened sidewalk and streetlights for pedestrians, and a retail storefront. The proposed building would have a modern, high-quality, and attractive building design, which would enhance the area, and would be consistent with the appearance of the surrounding buildings and with the intention of the UMIX designation and UMU zone.
The secondary stand-alone parking structure was designed to be of low visual impact, and would help screen office building 790 The City Drive South from the noise of Garden Grove Boulevard.
It would be 2-stories tall and would be clad in brick to match the exiting parking structure and offices. The existing large trees would remain in place and tall shrubs would be planted to help screen the parking structure on the façade facing Garden Grove Boulevard.
A shade and shadow study was completed for the proposed project (Figure 10) that analyzed the shade and shadow impacts of the proposed project during the summer and winter solstice in the morning and evening. The proposed mixed-use residential and commercial building would cast shadows to the east during the summer solstice and to the northeast during the winter solstice and would cast shadows to the west during the summer solstice and to the northwest during the winter solstice.
During the summer solstice, the shadows would be mostly confined to the project site and would not have an impact on nearby buildings. During the winter solstice, the building would cast longer shadows toward the northwest in the morning and toward the northeast in the evening. The buildings most impacted would be the office building to the northwest at 790 The City Drive South, the hotel to the north, and the office building to the northeast located at 785 The City Drive South. 40 However, the shadows cast by the proposed building would move away from these buildings in less than 2 hours and thus, would not significantly impact these land uses.
The proposed architectural design would be more compatible with the existing character of the office complex and would not be detrimental to the visual character and quality of the surrounding area. The visual changes introduced by the proposed project would not degrade the visual character of the project site or the surrounding area. Overall, the visual appearance would be improved and therefore would not result in substantial degradation of the character or quality of the site.
Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. 53150001 • 11/2021 | 9a_southeast_corner_rendering.cdr

49 (d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?
A significant impact may occur if a project were to introduce new sources of light or glare on or from the project site that adversely affect daytime or nighttime views, or which pose a safety hazard.
The project site and surrounding area currently contain numerous sources of light, including streetlights, security lighting, illuminated signage, indoor building illumination, and automobile headlights. Lighting for the proposed mixed-use residential and commercial building includes wall-mounted light fixtures, sidewalk lighting, interior lighting for the buildings and structures, and security lighting. Light and glare from the proposed project would be visible to the surrounding areas and from roadways. Although the proposed project would include lighting, these sources would be similar to the light sources of the existing office complex. The proposed project would comply with the Municipal Code Section 17.12.030, Lighting, which requires that lighting on any premises be directed, controlled, screened, or shaded in such a manner as not to shine directly on surrounding premises, and that lighting on any residential property be controlled to prevent glare or direct illumination of any public sidewalk or thoroughfare.17 As such, the proposed project would be required to direct, control, screen, or shade lighting such that it would not create a new source of substantial light or glare, adversely affect day or nighttime views, or create light spillover onto surrounding properties or public thoroughfares. Therefore, the proposed project is not expected to substantially increase the amount of light and glare on the project site or surrounding areas.
Additionally, glare occurs when sunlight is reflected off the surfaces of buildings or objects. The project site and surrounding area currently contain sources of glare from the existing buildings onsite. Although the proposed project would include building materials and improvements that could cause daytime glare, the proposed project would be required to comply with Municipal Code Section 17.12.030 to prevent glare, as discussed in the previous paragraph above Therefore, the proposed project would result in less than significant impacts.
Significance Determination: Less than significant impact.
Mitigation Measures: None.

Impact Analysis
(a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to nonagricultural use? A significant impact may occur if a project were to result in the conversion of State-designated agricultural land from agricultural use to another nonagricultural use. The project site is in an urbanized area of the City. According to the California Department of Conservation’s Farmland Mapping and Monitoring Program, the project vicinity is designated Urban and Built-Up Land, and the City of Orange contains less than 1 square mile that is considered unique farmland.18 There are no Prime Farmlands, Unique Farmlands, or Farmlands of Statewide Importance on the project site or adjacent to the project site. The nearest designated farmland is 3.42 miles northwest of the project site along the Union Pacific railroad in Anaheim. The proposed project would not affect any farmlands as mapped pursuant to the Farmland Mapping and Monitoring Program.
Additionally, the General Plan designates the site UMIX, and the site is zoned UMU. Therefore, no impacts would occur.

Environmental Setting
The project site is located in the South Coast Air Basin (SoCAB) within the jurisdiction of the South Coast Air Quality Management District (SCAQMD). While the final determination of whether a project is significant is within the purview of the Lead Agency pursuant to Section 15064(b) of the CEQA Guidelines, SCAQMD recommends that its quantitative air pollution thresholds be used to determine the significance of project emissions (Table 4). If the Lead Agency finds that the proposed project has the potential to exceed these air pollution thresholds, the proposed project should be considered to have significant air quality impacts. The SCAQMD has developed regional and Localized Significance Thresholds (LSTs) to evaluate construction and operational emissions within its jurisdiction. Note that the analysis evaluates a construction start date of December 2022. Extending the construction schedule by a year would ultimately reduce any potential impacts as CalEEMod presumes that future construction equipment would become more efficient. Furthermore, the analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Due to the reduction in building square footage on the proposed site, the project emissions related to both construction and operational activity would be lower than what is analyzed herein. Thus, this conservative analysis evaluates the worst-case scenario.

Localized Air Quality Significance Thresholds
The SCAQMD recommends that all air quality analyses include a localized assessment of both construction and operational emissions on nearby sensitive receptors. The SCAQMD has developed Localize Significance Threshold (LST) to be implemented at the discretion of local public agencies acting as a Lead Agency pursuant to CEQA Guidelines. LSTs represent maximum mass emissions from a project site that would not result in pollutant concentrations that exceed National Ambient Air Quality Standards (NAAQS) or California Ambient Air Quality Standards (CAAQS). LSTs are based on ambient concentrations of that pollutant within the Source Receptor Area (SRA)21 where a project is located, distance to the nearest sensitive receptor, and size of the project site, all of which are the primary factors that influence pollutant concentrations.
The SCAQMD provided the Final Localized Significance Threshold Methodology (dated June 2003, revised 2008) for guidance.22 The LST Methodology assists lead agencies in analyzing localized air quality impacts, particularly carbon monoxide (CO), oxides of nitrogen (NOX), particulate matter, including dust, 10 micrometers or less in diameter (PM10), and particulate matter, including dust, 2.5 micrometers or less in diameter (PM2.5). The SCAQMD provides LST mass rate lookup tables for projects with active construction areas that are less than or equal to 5 acres, providing specific thresholds for 1-acre, 2-acre, and 5-acre project sites.
As the proposed project would disturb approximately 2.95 acres across the mixed-use residential and commercial complex and proposed parking structure, the LSTs for a 2-acre project site was used in this analysis for a conservative assessment. These LST lookup values are provided to be used as a screening tool for identifying whether a more detailed analysis is needed for localized impacts. The appropriate LSTs can be determined based on the project’s SRA, size, and distance to nearest sensitive receptor. The appropriate SRA for the LSTs is Central Orange County (SRA 17) since this area includes the project site. LSTs apply to CO, nitrogen dioxide (NO2), PM10, and PM2.5. LSTs were obtained for sensitive receptors located 25 meters from the source area based on the proposed project’s proximity to existing sensitive receptors. 21 A source area is that area in which contaminants are discharged, and a receptor area is that area in which the contaminants accumulate and are measured. Any of the areas can be a source area, a receptor area, or both a source and receptor area. 22 South Coast Air Quality Management District (SCAQMD). 2021. Localized Significance Thresholds. Website:

Carbon Monoxide Hotspot Thresholds
The largest contributor of CO emissions during long-term operations of a residential development project is typically from motor vehicles. A CO hotspot represents a condition wherein high concentrations of CO may be produced by motor vehicles accessing a congested traffic intersection under heavy traffic volume conditions.
Since the first regulation of CO emissions from vehicles (model year 1966) in California, vehicle emissions standards for CO applicable to light duty vehicles have decreased tailpipe CO emissions by 96 percent for automobiles, and new cold weather CO standards have been implemented, effective for the 1996 model year. With the turnover of older vehicles, introduction of cleaner fuels and implementation of control technology on industrial facilities, CO concentrations in the South Coast Air Basin (SoCAB) have steadily declined.
The analysis prepared for CO attainment in the SoCAB by the SCAQMD can help evaluate the potential for CO exceedances in the SoCAB. CO attainment was thoroughly analyzed as part of the SCAQMD’s 2003 Air Quality Management Plan (2003 AQMP) and the 1992 Federal Attainment Plan for Carbon Monoxide (1992 CO Plan). As discussed in the 1992 CO Plan and subsequent plan updates, peak carbon monoxide concentrations in the SoCAB are due to unusual meteorological and topographical conditions and not the impact of particular intersections.23 Considering the region’s unique meteorological conditions and the increasingly stringent CO emissions standards, CO 23 California Air Resources Board (ARB). 2021. 2005 South Coast Carbon Monoxide Plan. Website:
https://ww2.arb.ca.gov/resources/documents/2005-south-coast-carbon-monoxide-plan. Accessed August 18, 2022. 56 modeling was performed as part of the 1992 CO Plan and subsequent plan updates and AQMPs. In the 1992 CO Plan, a CO hot spot analysis was conducted for four busy intersections in Los Angeles at the peak morning and afternoon time periods. The intersections evaluated included Long Beach Boulevard and Imperial Highway (Lynwood); Wilshire Boulevard and Veteran Avenue (Westwood); Sunset Boulevard and Highland Avenue (Hollywood); and La Cienega Boulevard and Century Boulevard (Inglewood). These analyses did not predict a violation of CO standards. The busiest intersection evaluated was that at Wilshire Boulevard and Veteran Avenue, which has a daily traffic volume of approximately 100,000 vehicles per day. These modeling results and the determinations of this CO hot spot analysis is utilized in this analysis as the basis for determining whether the proposed project would result in a CO hot spot at impacted intersections and roadway segments.
Health Risk Significance Thresholds
For pollutants without defined significance standards or air contaminants not covered by the standard criteria cited above, the definition of substantial pollutant concentrations varies. For toxic air contaminants (TAC), “substantial” is taken to mean that the individual cancer risk exceeds a threshold considered a prudent risk management level.
The SCAQMD has defined several health risk significance thresholds that it recommends lead agencies use in assessing a project’s health risk impacts. The City of Orange has not adopted its own set of thresholds. Therefore, the following SCAQMD thresholds are used for this analysis.
Project-Specific Health Risk Significance Thresholds
The SCAQMD has established the following project-specific health risk significance thresholds:
13 • Maximum Incremental Cancer Risk: >=10 in 1 million. • Hazard Index (project increment) >=1.0.
A significant impact would occur if a project’s impacts exceeded any of these thresholds.
Cumulative Health Risk Significance Thresholds
When the proposed project, in combination with one or more other projects exceeds the projectspecific significance thresholds, the project is considered by the SCAQMD to be cumulatively considerable. This is the reason project-specific and cumulative significance thresholds are the same. Conversely, projects that do not exceed the project-specific thresholds are generally not considered to be cumulatively significant.
Impact Analysis
Conflict with or obstruct implementation of the applicable air quality plan? The SCAQMD CEQA Air Quality Handbook states that there are two key indicators to evaluate whether or not a project conflicts with or obstructs the implementation of the applicable air quality plan (2016 AQMP for the SoCAB). These indicators are (1) whether the project will not result in an increase in the frequency or severity of existing air quality violations or cause or contribute to 57 new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP; and, (2) whether a project is inconsistent with the growth assumptions incorporated into the air quality plan, and thus, whether it would interfere with the region’s ability to comply with NAAQS and CAAQS.
Considering the recommended indicators in the CEQA Air Quality Handbook, this analysis uses the following criteria to address this potential impact:
• Criterion 1: The project’s contribution to air quality violations (SCAQMD’s first indicator);
• Criterion 2: Assumptions in the AQMP (SCAQMD’s second indicator); and • Criterion 3: Compliance with applicable emission control measures in the AQMPs.
Criterion 1: The Project’s Contribution to Air Quality Violations According to the SCAQMD, a proposed project would be consistent with the AQMP if the proposed project can demonstrate it would not:
• result in an increase in the frequency or severity of existing air quality violations; or • cause or contribute to new violations or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP.
If a project’s emissions exceed the SCAQMD regional thresholds for NOX, volatile organic compounds (VOC), PM10, or PM2.5, it follows that the emissions could cumulatively contribute to an exceedance of a pollutant for which the basin is in nonattainment (ozone, PM10, PM2.5) at a monitoring station in the basin. An exceedance of a nonattainment pollutant at a monitoring station would not be consistent with the goals of the AQMP—to achieve attainment of pollutants standards.
As discussed in Impact 5.3(b) later in this section, the proposed project would not exceed the SCAQMD regional significance thresholds or LSTs during construction or operation. Therefore, the proposed project would be consistent with the AQMP. The proposed project meets this criterion, and impacts would be less than significant.
Criterion 2: Assumptions in the AQMP
According to Chapter 12 of the SCAQMD CEQA Air Quality Handbook, the purpose of the General Plan consistency finding is to determine whether a project is inconsistent with the growth assumptions incorporated into the air quality plan and, thus, whether it would interfere with the region’s ability to comply with federal and California air quality standards.
The General Plan was adopted prior to adoption the Southern California Association of Governments (SCAG) Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), which was adopted in April 2016 and was used to inform the population and emissions 58 growth forecast for the SCAQMD’s most recent AQMP. The SCAQMD adopted the 2016 AQMP on March 3, 2017, which utilized the population growth forecasts contained in SCAG’s 2016 RTP/SCS. It should be noted that there is a more current version of the SCAG RTP/SCS which was adopted September 2022; however, the 2022 AQMP has not yet been adopted at the time of this writing.
The project site’s land use designation is Urban Mixed-Use.24 The Urban Mixed-Use designation allows development with a 1.5-3.0 FAR and 30 to 60 dwelling units per acre.25 The maximum development on the site under the Urban Mixed-Use designation is a 3.0 FAR. The proposed project includes the construction and operation of a 225-unit apartment building with retail space, resulting in 1.44 FAR. Implementation of the proposed project would not exceed the maximum development of the site allowed in the General Plan Land Use Element.
As the proposed project would not exceed the maximum extent of development anticipated at the project site under the land use scenario envisioned by SCAG’s 2016 RTP/SCS, emissions generated by operation of the proposed project would have been included in growth forecasts for the current AQMP. Furthermore, the jobs introduced by the proposed project would consist of those working in general retail or building maintenance, and would not be highly specialized occupations. Thus, it is not anticipated that the jobs generated by the proposed project would generate additional population growth from people moving to the City of Orange from out of the area. Therefore, the proposed project would not adversely affect growth assumptions within the AQMP. The impact for this criterion would be less than significant.
Criterion 3: Control Measures
The proposed project would be required to comply with all applicable rules and regulations of the SCAQMD. Because the proposed project includes earthmoving activity, SCAQMD Rule 403 would apply. SCAQMD Rule 403 governs emissions of fugitive dust during construction and operation activities. The rule requires that fugitive dust be controlled with best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. In addition, SCAQMD Rule 403 requires the implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off-site.
Compliance with this rule is achieved through application of standard Best Management Practices (BMPs). These BMPs include application of water or chemical stabilizers to disturbed soils; covering haul vehicles; restricting vehicle speeds on unpaved roads to 15 miles per hour; sweeping loose dirt from paved site access roadways; cessation of construction activity when winds exceed 25 miles per hour; and establishing a permanent ground cover on finished sites. The proposed project’s compliance with SCAQMD Rule 403 would result in consistency with the applicable AQMP control measures.

The proposed project would meet all three criteria for determining consistency with the AQMP.
The proposed project would not result in a regional or localized exceedance of criteria air pollutants and would not exceed the growth assumptions in the AQMP. The proposed project would comply with all applicable SCAQMD rules and regulations. Accordingly, the proposed project would not conflict with or obstruct implementation of the applicable air quality plans, and therefore, the impact would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or State ambient air quality standard?
This impact is related to the cumulative effect of a project’s regional criteria pollutant emissions.
The region is currently in nonattainment for ozone, PM10, and PM2.5. By its nature, air pollution is largely a cumulative impact resulting from emissions generated over a large geographic region.
The nonattainment status of regional pollutants is a result of past and present development within the air basin, and this regional impact is a cumulative impact. To clarify, new development projects (such as the proposed project) within the air basin would contribute to this impact only on a cumulative basis. No single project would be sufficient in size, by itself, to result in nonattainment of regional air quality standards. Instead, a project’s emissions may be individually limited, but cumulatively considerable when taken in combination with past, present, and future development projects. All new developments that would increase air pollutant emissions above those assumed in regional air quality plans would contribute to cumulative air quality impacts.
The cumulative analysis focuses on whether a specific project would result in cumulatively considerable emissions. According to Section 15064(h)(4) of the CEQA Guidelines, the existence of significant cumulative impacts caused by other projects alone does not constitute substantial evidence that the project’s incremental effects would be cumulatively considerable. Rather, the determination of cumulative air quality impacts for construction and operational emissions is based on whether the project would result in emissions that exceed SCAQMD regional or localized thresholds of significance for construction and operations on a project level. Projects that generate emissions below the SCAQMD significance thresholds would be considered consistent with regional air quality planning efforts would not generate cumulatively considerable emissions.
Localized Significance Thresholds
The SCAQMD Governing Board adopted a methodology for calculating localized air quality impacts through LSTs. The SCAQMD has subdivided the SoCAB into 36 separate SRAs where emissions can originate or where receptors could be impacted from emission sources located in other SRAs. To facilitate the localized assessment process, the SCAQMD provides a series of 60 lookup tables that contain LSTs for each SRA within the basin for quantifying both construction and operational impacts. The proposed project is located within SRA 17, Central Orange County.
In addition to the dependence on geographic location within the SCAQMD (e.g., the SRA), the localized thresholds also depend on the distance to the impacted receptor from the source of emissions. The nearest sensitive receptors are the residences immediately to the south of the project site, which are within 25 meters of the proposed project boundary.
The California Emissions Estimator Model (CalEEMod) Version 2016.3.2 was used to estimate construction emissions. Construction of the proposed project would include demolition, site preparation, grading, building construction, paving, and architectural coating activities. Table 6 displays the proposed construction schedule, as provided by the project applicant, and demonstrates that the proposed project would be constructed over approximately 1.5 years, beginning as early as December 2022.26 The CalEEMod construction phase lengths were based on information provided by the project applicant. To conserve the model’s default construction equipment list and activity intensity, the same default construction equipment horsepower-hour quantities were applied to the adjusted schedule provided by the project applicant. If the construction schedule moves to later years, construction fuel consumption may decrease because of improvements in technology and more stringent regulatory requirements as older, less fuelefficient equipment is gradually replaced by newer and more fuel-efficient equipment. Please see Appendix A for more detailed modeling information.

The localized assessment methodology limits the emissions in the analysis to those generated from on-site activities. The on-site emissions generated during construction are compared with the LSTs and summarized in Table 7. The emissions estimates shown therein incorporate required regulatory compliance, such as SCAQMD Rule 403. Note that because of the way CalEEMod is constructed, compliance with SCAQMD Rule 403 is reflected as mitigation in the output, although compliance 26 Note that the analysis evaluates a construction start date of December 2022. Extending the construction schedule by a year would ultimately reduce any potential impacts as CalEEMod presumes that future construction equipment would become more efficient. Furthermore, the analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Due to the reduction in building square footage on the proposed site, the project emissions related to both construction and operational activity will be lower than what is analyzed herein. Thus, this conservative analysis evaluates the worstcase scenario. 61 with Rule 403 is mandatory and not considered mitigation under CEQA Guidelines. As shown therein, the construction of the proposed project would not exceed the SCAQMD’s construction LSTs.

The on-site emissions during operation are compared with the LSTs and summarized in Table 8 below. Emissions that would be generated during operation of the existing land uses on the project site are not presented here. Existing operational emissions would be generated by the use of consumer products, fertilizers, and degreasers; the combustion of natural gas for space heating and appliance operation; and the operation of vehicles by the existing facility’s employees and patrons.
Therefore, emissions presented in Table 8 represent a conservative assessment of emissions generated by the proposed project. As described above, the LST Methodology recommends that only on-site emissions are evaluated using LSTs. Most of the proposed project’s mobile source 62 emissions would occur on the local and regional roadway network away from the proposed project, and only on-site mobile source emissions need to be included in this analysis. A trip length of 0.1 mile was used in the modeling input assumptions to estimate on-site emissions from mobile sources. As shown in Table 8, emissions during operation do not exceed the LSTs.

The localized analyses use thresholds that represent the maximum project emissions that would not cause or contribute to an exceedance of the most stringent applicable federal or State ambient air quality standard. If the proposed project results in emissions that do not exceed the LSTs, it follows that those emissions would not cause or contribute to a local exceedance of the appropriate ambient air quality standard. As shown in Table 8, the localized construction analysis demonstrates that the proposed project would not exceed the LSTs for NO2, CO, PM10, or PM2.5. Further, as shown in Table 8, on-site project operational emissions would not exceed the operational LSTs for NO2, CO, PM10, or PM2.5. Therefore, the proposed project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation during construction or operations.
Regional Air Quality Thresholds
Table 9 summarizes construction-generated emissions with standard conditions incorporated. As previously mentioned, the proposed project would be required to comply with standard SCAQMD regulations, such as implementing SCAQMD Rule 403, which would reduce fugitive dust emissions. For more detailed information on modeling inputs, please refer to Appendix A. 63 The information shown in Table 9 demonstrates that the SCAQMD regional emission thresholds would not be exceeded during construction activities. Therefore, the short-term construction emissions are considered to have a less than significant regional impact.

Operational Regional Emissions
CalEEMod Version 2016.3.2 was used to estimate operational emissions that would occur during operation of the proposed project. Operational emissions are generated based on area, energy, and mobile sources. Area sources would include activities such as landscape maintenance, consumer product usage, and occasional application of architectural coatings. Energy sources would include natural gas combustion for space and water heating. Mobile sources would include vehicle trips 64 associated with vehicles accessing the project site. Mobile trip characteristics are based on the Traffic Impact Analysis (TIA) prepared by Linscott, Law and Greenspan, Engineers, (LLG) dated December 11, 2020 (Revised September 21, 2022), for the proposed project, which is included in Appendix K-1. It should be noted that the TIA conservatively evaluates the development of 226 apartment units and 9,169 square feet of retail uses, even though the proposed project would develop 225 apartment units and 9,000 square feet of retail uses.
Daily operational emissions were estimated for the summer and winter seasons. The maximum daily operational emissions between the summer and winter seasons, as derived from CalEEMod, are shown in Table 10. Modeling results for both seasons are found in Appendix A.
Table 10 presents the operational emissions generated by the proposed project. Emissions that would be generated during operation of the existing land uses on the project site are not presented here.
Existing operational emissions would be generated by the use of consumer products, fertilizers, and degreasers; the combustion of natural gas for space and water heating and appliance operation; and the operation of vehicles by the existing facility’s employees and patrons. Therefore, emissions presented in Table 10 represent a conservative assessment of emissions generated by the proposed project. The information shown in Table 10 demonstrates that the SCAQMD regional emission thresholds would not be exceeded during operation of the proposed project. Therefore, the long-term operational emissions are considered to result in a less than significant regional impact.

As indicated in Table 7 and Table 8, the proposed project would not exceed SCAQMD LSTs during construction or operation. Additionally, as indicated in Table 9 and Table 10, the proposed project would not exceed SCAQMD thresholds during construction or operation. Therefore, the proposed project would result in less than significant impacts.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (c) Expose sensitive receptors to substantial pollutant concentrations This impact evaluates the potential for the proposed project’s construction and operational emissions to expose sensitive receptors to substantial pollutant concentration. Sensitive receptors are defined as those individuals who are sensitive to air pollution including children, the elderly, and persons with preexisting respiratory or cardiovascular illness. For purposes of CEQA, the SCAQMD considers a sensitive receptor to be a location where a sensitive individual could remain for 24 hours, such as residences, hospitals, or convalescent facilities. Commercial and industrial facilities are not included in the definition because employees do not typically remain on-site for 24 hours. However, when assessing the impact of pollutants with 1-hour or 8-hour standards (such as nitrogen dioxide and CO), commercial and/or industrial facilities would be considered sensitive receptors.
The nearest sensitive receptors to the proposed project would be the single-family residences approximately 25 meters north of the northern boundary of the project site. The next closest sensitive receptors to the proposed project would be the single-family residences approximately 30 meters south of the project site, across from West Garden Grove Boulevard.
Naturally Occurring Asbestos
Asbestos is a fibrous mineral which is both naturally occurring in ultramafic rock (a rock type commonly found in California) and used as a processed component of building materials. Because asbestos has been proven to cause a number of disabling and fatal diseases, such as asbestosis and lung cancer, it is strictly regulated either based on its natural widespread occurrence, or in its use as a building material. In addition, the ARB approved an Airborne Toxic Control Measure (ATCM) for construction, grading, quarrying, and surface mining operations to minimize emissions of naturally occurring asbestos (NOA). The regulation requires application of BMPs to control fugitive dust in areas known to have NOA and requires notification to the local air district prior to commencement of ground-disturbing activities.
The California Department of Conservation, Division of Mines and Geology (CDMG) has a published guide for generally identifying areas that are likely to contain NOA. The CDMG map indicates NOA are not known to occur within the project area.27 Therefore, disturbance of NOA 27 United States Geological Survey (USGS). 2011. Reported Historic Asbestos Mines, Historic Asbestos Prospects, and Other Natural Occurrences of Asbestos in California. Website: https://pubs.usgs.gov/of/2011/1188/. Accessed August 18, 2022. 66 during project construction is not a concern for the proposed project. The proposed project would result in no impact from exposure of sensitive receptors to NOA.
Construction: Diesel Particulate Matter
The proposed project would generate diesel exhaust, a source of diesel particulate matter, during project construction. On-site emissions of both diesel particulate matter occur during construction from the operation of heavy-duty construction equipment and from vendor trucks that operate on project sites.
Construction activities that would generate diesel particulate matter emissions are short-term in nature. Moreover, the current methodological protocols required by the SCAQMD and ARB when studying the health risk posed by diesel particulate matter assume the following: (1) 24-hour constant exposure; (2) 350 days a year; (3) for a continuous period lasting 30 years. In addition, as shown in Impact 5.3(b), the proposed project would not exceed the LST for construction-generated criteria pollutants. Therefore, the proposed project would not expose receptors to substantial criteria pollutant concentrations from construction activities. Considering the dispersion of the emissions, the short construction time frame, and the less than significant impact related to LSTs, indicating that no further analysis would be required, exposure to diesel particulate matter would be less than significant.
Operation: Toxic Air Pollutants
The proposed project would not include any substantial sources of TAC emissions. Nonetheless, the proposed project would place new sensitive receptors which may be exposed to existing sources of TACs. Major sources of TACs include autobody shops, distribution centers, industrial manufacturing sites, landfills, truck stops, farming operations, power plants, quarries, and similar land uses. No land uses which fit these descriptions are present in the immediate vicinity to the project site.
Furthermore, the ARB advises the siting of new sensitive land uses (e.g., residences) greater than 500 feet from freeways or roadways which receive 100,000 vehicles per day.28 As presented in the TIA prepared for the proposed project (Appendix K-1), nearby roadways experience as much as 6,069 vehicles per day during PM peak-hours. As an industry standard, the PM peak-hour vehicle trips were multiplied by 10 to identify a daily vehicle trip count of an estimated 60,690 vehicles per day. Moreover, the closest freeway to the proposed project, SR-22, is approximately 1,130 feet north of the project site. Therefore, operation of the proposed project would not expose sensitive receptors to substantial pollutant concentrations. This impact would be less than significant.
Operation: CO Hotspot
As previously discussed, a CO hot spot analysis was conducted for four busy intersections in Los Angeles at the peak morning and afternoon time periods in the SCAQMD’s 1992 CO Plan. The intersections evaluated included Long Beach Boulevard and Imperial Highway (Lynwood); 28 California Air Resources Board (ARB). 2005. Air Quality and Land Use Handbook: A Community Health Perspective. April. Website:
https://ww3.arb.ca.gov/ch/handbook.pdf. Accessed August 18, 2022. 67 Wilshire Boulevard and Veteran Avenue (Westwood); Sunset Boulevard and Highland Avenue (Hollywood); and La Cienega Boulevard and Century Boulevard (Inglewood).29 These analyses did not predict a violation of CO standards. The busiest intersection evaluated was that at Wilshire Boulevard and Veteran Avenue, which has a daily traffic volume of approximately 100,000 vehicles per day. Therefore, if operation of the proposed project results in less than 100,000 daily vehicle trips at affected intersections or roadways segments under Existing Plus Project conditions, then a less than significant CO impact would occur.
The TIA prepared for the proposed project (see Appendix K-1) identified the Existing Plus Project traffic volumes for four key roadway segments affected by the proposed project. As identified in the TIA, the Existing Plus Project daily vehicle trips, after considering the vehicle trips generated by the existing operations on the project site, would total 21,946 daily vehicle trips along Garden Grove Boulevard (west of the project site), 25,737 daily vehicle trips along Memory Lane (east of the project site), 21,331 daily vehicle trips along The City Drive (north of the project site), and 22,252 daily vehicle trips along Metropolitan Drive (north of the project site). Considering that the greatest traffic volume under Existing Plus Project conditions would be up to 47,068 daily vehicles at the intersection of The City Drive and Memory Lane, the proposed project would not result in a significant impact to air quality for local CO or expose receptors to substantial CO concentrations from operational activities.
Conclusion
As demonstrated above, nearby sensitive receptors would not be exposed to substantial pollutant concentrations during construction or operation of the proposed project. Therefore, the proposed project would result in less than significant impacts.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Odors can cause a variety of responses. The impact of an odor is dependent on interacting factors such as frequency (how often), intensity (strength), duration (in time), offensiveness (unpleasantness), location, and sensory perception. While offensive odors rarely cause any physical harm, they still can be very unpleasant, leading to considerable distress and often generating citizen complaints to local governments and regulatory agencies. Odor-related symptoms reported in a number of studies include nervousness, headache, sleeplessness, fatigue, 29 South Coast Air Quality Management District (SCAQMD). 2003.

This rule on Public Nuisance Regulation states: “A person 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.” The SCAQMD does not provide a suggested screening distance for a variety of odor-generating land uses and operations, nor does the City have a defined methodology for analyzing potential odor impacts from land-use development projects. In the absence of SCAQMD or City guidance on assessing odor impacts, the San Joaquin Valley Air Pollution Control District’s (Valley Air District) screening distances for odor sources were used in this analysis to determine the proposed project’s potential to adversely affect a substantial number of people. Those distances are used as a guide to assess whether nearby facilities could be sources of significant odors. Projects that would site a new receptor farther than the applicable screening distances from an existing odor source would not be likely to have a significant impact. These screening distances by type of odor generator are listed in Table 11.

Construction-Related Odors
Potential sources that may emit odors during construction activities include exhaust from diesel construction equipment. However, because of the temporary nature of these emissions, the intermittent nature of construction activities, and the highly diffusive diesel PM exhaust properties, nearby receptors would not be affected by diesel exhaust odors associated with project construction. Odors from these sources would be localized and generally confined to the immediate area surrounding the project site. The proposed project would utilize typical construction techniques, and the odors would be typical of most construction sites and temporary in nature. Impacts would be less than significant.
Operational-Related Odors
The proposed project would demolish a 12,923-square-foot, single-story commercial building and develop a mixed-use 6-story building with a 3-story subterranean basement parking structure, and 2-story stand-alone open parking structure. The apartment building would feature retail space, a fitness center, lobby and lounge area, and a swimming pool courtyard. Residential and retail developments are not typical odor-generating land uses. Land uses typically considered associated with odors include wastewater treatment facilities, waste disposal facilities, or agricultural operations. Minor sources of odors, such as exhaust from mobile sources, are not typically associated with numerous odor complaints, but are known to have temporary and less concentrated odors. The proposed project’s long-term operational activities would not have any substantial odor sources that would expose nearby receptors. Considering the low intensity of potential odor emissions, the proposed project’s operational activities would not expose receptors to objectionable odor emissions. Impacts would be less than significant.
The Project as a Sensitive Receptor
As a predominantly residential project, the proposed project has the potential to place sensitive receptors near existing odor sources. The project site is not located within 2 miles of a wastewater treatment facility or a petroleum refinery. There are no solid waste facilities or other major odor generating sources listed in Table 11 within their respective screening distance of the project site.
Therefore, the proposed project would not introduce sensitive receptors which may be exposed to substantial existing odor impacts. This impact would be less than significant.

Environmental Setting
The project site is located in Orange County, which is part of the greater Los Angeles metropolitan region. The northwestern portion of the County lies on the coastal plain of the Los Angeles Basin and the southeastern portion rises into the foothills of the Santa Ana Mountains. Orange County is bordered on the southwest by the Pacific Ocean. The major watercourse in this area is the Santa Ana River, which is located approximately 500 feet east of the project site. The local area surrounding the project site is characterized by extensive urban development and contains limited areas of naturally occurring habitats. Note that the following analysis is based on a larger study area than what is currently proposed. The analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Thus, this conservative analysis evaluates the worst-case scenario.
Field Survey
On October 6, 2020, a FirstCarbon Solutions (FCS) Biologist conducted a biological pedestrian survey of the project site between 10:00 a.m. and 10:45 a.m. Weather conditions were sunny with an average temperature of 82°F (degrees Fahrenheit).
The entire project site is currently developed with a hardscaped parking lot, ornamental vegetation and a small strip mall located in the southern portion of the site. Plant species observed consisted mainly of ornamental vegetation and trees, including Indian laurel (Ficus macrocarpa), coral gum 71 (Eucalyptus torquate), and Mexican fan palm (Washingtonia robusta). Other ornamental plants observed on-site included New Zealand flax (Phormium sp.) Mexican feathergrass (Nassella tenuissima), and bird of paradise flower (Strelitzia sp.).
Wildlife observed on-site included non-native house sparrows (Passer domesticus), while a California gull (Larus californicus) and a flock of mourning doves (Zenaida macroura) were observed flying over the site.
Impact Analysis
(a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service?
Prior to the field survey, FCS Biologists conducted a desktop search to determine whether any special-status species have potential to occur within the project site. The review was based on a search of the California Department of Fish and Wildlife’s (CDFW) California Natural Diversity Database (CNDDB), a special-status species and plant community account database, and the California Native Plant Society Electronic Inventory (CNPSEI) of Rare and Endangered Vascular Plants of California database for the Anaheim, California USGS 7.5-minute Quadrangle Map as well as its eight neighboring quadrangle maps (Appendix B-1).32,33 Special-status plants recorded in the vicinity of the project site included chaparral sand-verbena (Abronia villosa var. aurita), southern tarplant (Centromadia parryi ssp. australis), Gambel’s water cress (Nasturtium gambelii), salt spring checkerbloom (Sidalcea neomexicana), and San Bernardino aster (Symphyotrichum defoliatum). Because of the completely developed state of the project site, none of these special-status plants are expected to occur due to the lack of suitable habitat such as coastal sage scrub, chaparral, or grassland vegetation communities. The lack of marshes and swamps on-site precludes the presence of the remaining plant species recorded in the CNDDB and CNPSEI searches.
According to the CNDDB, 59 special-status wildlife species were recorded in the vicinity of the project site. Because of the completely developed state of the project site, none of these specialstatus wildlife species are expected to occur on-site. The majority of records are associated with the Santa Ana River and are unlikely to occur on-site due to the lack of suitable riparian habitat.
These species include western yellow-billed cuckoo (Coccyzus americanus occidentalis), California black rail (Laterallus jamaicensis coturniculus), steelhead (Oncorhynchus mykiss irideus), and least Bell’s vireo (Vireo bellii pusillus). Other terrestrial species recorded in the project vicinity are unlikely to occur on-site due to exposed soil as well as the lack natural 32 California Department of Fish and Wildlife (CDFW). 2020.

These species include Southern California legless lizard (Anniella stebbinsi) and coast horned lizard (Phrynosoma blainvillii). Additionally, no special-status bat species are expected to occur due to the lack of suitable roosting habitat in the form of abandoned buildings with accessible crevices.
The project site contains numerous ornamental trees that may provide suitable habitat for native nesting birds. The removal of these trees during the nesting season could potentially impact nesting birds. As a precaution, pre-construction surveys for nesting birds as described in Mitigation Measure (MM) BIO-1 shall be implemented prior to the start of any construction activities.
Implementation of this mitigation measure would reduce potentially significant impacts on nesting birds to less than significant.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM BIO-1 Pre-Construction Surveys for Nesting Birds
Construction activities that occur during the avian nesting season (generally February 15 to August 31) would disturb nesting sites for bird native species protected by the Migratory Bird Treaty Act (MBTA) and California Fish and Game Code. No action is necessary if no active nests of native species are found during a pre-construction nesting bird survey or if construction occurs during the nonbreeding season (generally September 1 through February 14).
Implementation of the following avoidance and minimization measures would reduce impacts to nesting birds.
1. To prevent impacts to MBTA-protected birds, nesting raptors, and their nests, removal of trees shall be limited to only those necessary to construct the proposed project.
2. If any tree removal is necessary, then it shall occur outside the nesting season between September 1 and February 14. If trees cannot be removed outside of the nesting season, pre-construction surveys shall be conducted 3 days prior to tree removal to verify the absence of active nests.
3. If an active nest of a native species is located during pre-construction surveys, the United States Fish and Wildlife Service (USFWS) and/or the California Department of Fish and Wildlife (CDFW) (as appropriate) shall be notified regarding the status of the nest. Construction activities shall be restricted, as necessary, to avoid disturbance of the nest until the young have fledged and/or it is abandoned, or the agencies deem disturbance potential to be minimal.
Restrictions may include establishment of exclusion zones (no ingress of personnel or equipment at a minimum radius of 100 feet around an active raptor nest and a 50-foot radius around an active migratory bird nest) or alteration of the construction schedule.
73 4. A qualified Biologist shall delineate the buffer using Environmentally Sensitive Area fencing, pin flags, and or yellow caution tape. The buffer zone shall be maintained around the active nest site(s) until the young have fledged and are foraging independently.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service? The project site is entirely developed and is absent of any native vegetation and does not contain any sensitive plant communities. The project site is not located adjacent to any riparian habitat.
Although, the project site is located approximately 500 feet west of Santa Ana River (Figure 2), the proposed project is not expected to cause impact to this nearby riparian habitat in any measurable way. Therefore, the proposed project would result in a less than significant impact.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (c) Have a substantial adverse effect on State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
Prior to conducting the field survey of the project site, FCS Biologists reviewed existing topographic maps, aerial photography as well as the online resources including the Watershed Assessment, Tracking and Environmental Results System (WATERS) to determine whether any potentially jurisdictional water bodies or wetlands exist within the vicinity of the project site. 34 The project site is entirely developed and does not contain any potential jurisdictional waters or wetlands. The nearest jurisdictional water body is the Santa Ana River, which is located approximately 500 feet east of the project site. Therefore, no impact would occur.
Significance Determination: No impact.
Mitigation Measures: None.

74 (d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
The development of the proposed project is not expected to interfere with the movement of wildlife. The project site is currently developed and is surrounded in all directions by extensive urban development. Although, the Santa Ana River serves as an important movement corridor for terrestrial and aquatic wildlife, the proposed project would not affect this area because the project site is located 500 feet west and would not alter the Santa Ana River. Therefore, no impact would occur.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?
FCS evaluated the site in response to the City’s Master Street Tree Plan and Preservation Ordinance and conducted a field survey on October 6, 2020.
35 The project site contains numerous ornamental
trees that consist of largely of three species: Indian laurel, coral gum, and Mexican fan palm. Based on current project design plans it is assumed that all of the trees currently present on-site would need to be removed in order to accommodate the proposed project. However, none of these trees meet the City’s definition of a “protected tree” and therefore do not require the permission of the City to be removed. The proposed project would not conflict with City Ordinances and therefore would have no impact.

Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan?

Descriptions and analysis in this section are based on information provided by the California Native American Heritage Commission (NAHC), South Central Coastal Information Center (SCCIC), National Register of Historic Places (NRHP), California Register of Historical Resources (CRHR), California Historic Landmarks list, California Points of Historic Interest list, and the California Built Environment Resource Directory (BERD). Non-confidential records search results and other correspondence is included in Appendix C-1 and Appendix C-2. Note that the following analysis is based on a larger study area than what is currently proposed. The analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Thus, this conservative analysis evaluates the worst-case scenario.
South Central Coastal Information Center
A cultural records search and literature review were conducted on October 8, 2020, at the SCCIC located at California State University, Fullerton, for the project site and a 0.5-mile radius beyond the project boundaries. The purpose of this review was to access existing cultural resource survey reports, archaeological site records, historic aerial photographs, and historic maps to evaluate whether any previously documented prehistoric or historic archaeological sites, architectural resources, cultural landscapes, or other resources exist within or near the project site. 77 The results of the records search indicate that there are no cultural resources located within the
0.5-mile radius nor within the project site. Twenty-one area-specific reports are on file with the SCCIC for the project site and the 0.5-mile radius. Reports OR-02272 and OR-04085 address the project site, indicating that it has previously been surveyed for cultural resources. A records search map identifying the project boundaries and a 0.5-mile radius along with non-confidential records search results can be found in Appendix C-2.
Pedestrian Survey
On October 16, 2020, FCS Staff Archaeologist, Kweku A. Williams, MA, RPA, conducted a pedestrian survey for unrecorded cultural resources within the project site. The survey covered the subject property where possible, beginning in the southern portion of the project site and moving north, using north–south transects spaced at 15‐meter intervals. The project site is divided into three parcels separated by a series of office buildings and driving entry ways. The areas under survey were hardscaped black top, mostly parking lots. For each parcel there was total of four transects. Based on the site map, the parcels ran parallel to City Drive South and east to west on Garden Grove Boulevard. The transects on the eastern side of the map were surveyed west to east, parallel to Garden Grove Boulevard. Survey conditions were documented using digital photographs and field notes.
There was no native soil exposed. All three parcels were hardscaped. Observations attempting to note any cultural resources proved impossible due to the number of hardscaped surfaces through the areas of survey. Overall, only modern debris was on the surface of all three parcels. No historic or prehistoric cultural resources or raw materials commonly used in the manufacture of tools (e.g., obsidian, Franciscan chert) were observed. The survey photographs indicate that all three parcels are hardscaped blacktop surfaces. Photographs from the pedestrian survey can be found in Appendix C-3.
Native American Heritage Commission
On September 24, 2020, FCS sent a request to the NAHC in an effort to determine whether any sacred sites are listed on its Sacred Lands File for the project site. A response was received on September 29, 2020, indicating that the Sacred Lands File search failed to locate the presence of Native American cultural resources within the immediate project site. The NAHC provided a list of 17 tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential Tribal Cultural Resources (TCRs) that may be affected by the project are addressed, a letter containing project information requesting any additional information was sent to each tribal representative on October 12, 2020. A response was received on November 5, 2020, from the Juaneño Band of Mission Indians, Acjachemen Nation-Belardes, requesting that the Tribe be notified and included in the initial ground disturbance for monitoring.
Correspondence related to the NAHC letters and tribal representatives can be found in Appendix C-1.
78 Impact Analysis
(a) Cause a substantial adverse change in the significance of a historical resource pursuant to Section 15064.5?
The records search conducted at SCCIC and the pedestrian survey failed to identify any historical resources located within 0.5-mile search radius or within the project site. There is one building located within the project site, however, it was built in 1989, therefore it is not eligible for listing on the NRHP or CRHR. As such, the proposed construction and ground disturbance would not result in adverse change or cause a loss in significance to the project site. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5?
The results from the SCCIC failed to identify any cultural resources located within the project site or 0.5-mile search radius. The proposed project is located in a developed area that is hardscaped with no exposed soil. Thus, the potential to impact an unidentified archaeological resource is considered low. However, it is possible that excavation and ground disturbance activities associated with project construction could encounter previously undiscovered archaeological resources. Archaeological resources can include but are not limited to stone, bone, wood, or shell artifacts or features, including hearths and structural elements. Damage or destruction of these resources would be a potentially significant impact. Implementation of MM CUL-1 Inadvertent Discovery of Cultural Resources would ensure that this potentially significant impact is reduced to less than significant.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM CUL-1 Inadvertent Discovery of Cultural Resources
In the event that buried cultural resources are discovered during construction, operations shall stop in the immediate vicinity of the find and a qualified Archaeologist shall be consulted to determine whether the resource requires further study. The qualified Archaeologist shall make recommendations to the Lead Agency on the measures that shall be implemented to protect the discovered resources, including but not limited to excavation and evaluation of the finds in accordance with Section 15064.5 of the CEQA Guidelines. Potentially significant cultural resources consist of but are not limited to stone, bone, fossils, wood, or shell artifacts or features, including hearths, structural remains, or historic dumpsites. Any previously undiscovered resources found during construction 79 within the project area shall be recorded on appropriate California Department of Parks and Recreation (DPR) forms and evaluated for significance in terms of CEQA criteria.
If the resources are determined to be unique historic resources as defined under Section 15064.5 of the CEQA Guidelines, mitigation measures shall be identified by the Archaeological Monitor and recommended to the Lead Agency. Appropriate mitigation measures for significant resources could include avoidance or capping, incorporation of the site in green space, parks, or open space, or data recovery excavations of the finds.
No further grading shall occur in the area of the discovery until the Lead Agency approves the measures to protect these resources. Any archaeological artifacts recovered as a result of mitigation shall be donated to a qualified scientific institution approved by the Lead Agency where they would be afforded long-term preservation to allow future scientific study.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(c) Disturb any human remains, including those interred outside of formal ceremonies? The project site is completely hardscaped; thus, the potential for human remains to be uncovered during ground disturbance is considered low. While it is highly unlikely that the presence of human remains exists within or near the project site, there is always the possibility that subsurface construction activities associated with the proposed project, such as grading or trenching, could potentially damage or destroy previously undiscovered human remains. In the event of the accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and 5097.98 must be followed. MM CUL-2 further specifies the procedures to follow in the event human remains are uncovered. Along with compliance with these guidelines and statutes, implementation of this mitigation would reduce potential impacts related to human remains to less than significant.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM CUL-2 Inadvertent Discovery of Human Remains
In the event of inadvertent discovery or recognition of any human remains, Public Resources Code Section 5097.98 must be followed. In this instance, once projectrelated earthmoving begins and if there is accidental discovery or recognition of any human remains, the following steps shall be taken:
1. There shall be no further excavation or disturbance of the site, or any nearby area reasonably suspected to overlie adjacent human remains until the County 80 Coroner is contacted to determine whether the remains are Native American and if an investigation of the cause of death is required. If the Coroner determines the remains to be Native American, the Coroner shall contact the NAHC within 24 hours, and the NAHC shall identify the person or persons it believes to be the “most likely descendant” of the deceased Native American.
The most likely descendant may make recommendations to the landowner or the person responsible for the excavation work, for means of treating or disposing of, with appropriate dignity, the human remains, and any associated grave goods as provided in Public Resources Code Section 5097.98, or Where the following conditions occur, the landowner or his/her authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity either in accordance with the recommendations of the most likely descendant or on the project area in a location not subject to further subsurface disturbance:
The NAHC is unable to identify a most likely descendant, or the most likely descendant failed to make a recommendation within 48 hours after being notified by the commission;
The descendant identified fails to make a recommendation; or The landowner or his authorized representative rejects the recommendation of the descendant, and the mediation by the NAHC fails to provide measures acceptable to the landowner.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
Tribal Cultural Resources
Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:
(d) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1 (k), or
A review of the CRHR, local registers of historic resources, a records search conducted at the SCCIC, and NAHC Sacred Lands File search failed to identify any listed TCRs that may be adversely affected by the proposed project. Additionally, the pedestrian survey, conducted on October 16, 2020, failed to identify any TCR’s. Nevertheless, should any undiscovered TCR’s be 81 encountered during the ground disturbance phase of the project, implementation of MM TCR-2 and MM TCR-3 would reduce impacts to less than significant.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM TCR-2 Unanticipated Discovery of Human Remains and Associated Funerary Objects
A. Native American human remains are defined in PRC 5097.98 (d)(l) as an inhumation or cremation, and in any state of decomposition or skeletal completeness. Funerary objects, called associated grave goods in Public Resources Code Section 5097.98, are also to be treated according to this statute.
B. If Native American human remains and/or grave goods discovered or recognized on the project site, then all construction activities shall immediately cease. Health and Safety Code Section 7050.5 dictates that any discoveries of human skeletal material shall be immediately reported to the County Coroner and all ground-disturbing activities shall immediately halt and shall remain halted until the coroner has determined the nature of the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe they are Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission, and Public Resources Code Section 5097.98 shall be followed.
C. Human remains and grave/burial goods shall be treated alike per California Public Resources Code section 5097.98(d)(1) and (2).
D. Construction activities may resume in other parts of the project site at a minimum of 200 feet away from discovered human remains and/or burial goods, if the Kizh determines in its sole discretion that resuming construction activities at that distance is acceptable and provides the project manager express consent of that determination (along with any other mitigation measures the Kizh monitor and/or archaeologist deems necessary). (CEQA Guidelines Section 15064.5(f).) E. Preservation in place (i.e., avoidance) is the preferred manner of treatment for discovered human remains and/or burial goods. Any historic archaeological material that is not Native American in origin (non-TCR) shall be curated at a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County or the Fowler Museum, if such an institution agrees to accept the material. If no institution accepts the archaeological material, it shall be offered to a local school or historical society in the area for educational purposes.
F. Any discovery of human remains/burial goods shall be kept confidential to prevent further disturbance.
82 MM TCR-3 Procedures for Burials and Funerary Remains:
A. As the Most Likely Descendant ("MLD"), the Koo-nas-gna Burial Policy shall be implemented. To the Tribe, the term "human remains" encompasses more than human bones. In ancient as well as historic times, Tribal Traditions included, but were not limited to, the preparation of the soil for burial, the burial of funerary objects with the deceased, and the ceremonial burning of human remains.
B. If the discovery of human remains includes four or more burials, the discovery location shall be treated as a cemetery and a separate treatment plan shall be created.
C. The prepared soil and cremation soils are to be treated in the same manner as bone fragments that remain intact. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later; other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects. Cremations will either be removed in bulk or by means as necessary to ensure complete recovery of all sacred materials.
D. In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can be moved by heavy equipment placed over the excavation opening to protect the remains. If this type of steel plate is not available, a 24-hour guard should be posted outside of working hours. The Tribe will make every effort to recommend diverting the project and keeping the remains in situ and protected. If the project cannot be diverted, it may be determined that burials will be removed.
E. In the event preservation in place is not possible despite good faith efforts by the project applicant/developer and/or landowner, before ground-disturbing activities may resume on the project site, the landowner shall arrange a designated site location within the footprint of the project for the respectful reburial of the human remains and/or ceremonial objects.
F. Each occurrence of human remains and associated funerary objects will be stored using opaque cloth bags. All human remains, funerary objects, sacred objects and objects of cultural patrimony will be removed to a secure container on site if possible. These items should be retained and reburied within six months of recovery. The site of reburial/repatriation shall be on the project site but at a location agreed upon between the Tribe and the landowner at a site to be protected in perpetuity. There shall be no publicity regarding any cultural materials recovered.
G. The Tribe will work closely with the project's qualified archaeologist to ensure that the excavation is treated carefully, ethically and respectfully. If data recovery is approved by the Tribe, documentation shall be prepared and shall include (at a minimum) detailed descriptive notes and sketches. All data recovery data recovery-related forms of documentation shall be approved in advance by the Tribe. If any data recovery is performed, once complete, a final report shall be submitted to the Tribe and the NAHC.
The Tribe does NOT authorize any scientific study or the utilization of any invasive and/or destructive diagnostics on human remains.
83 Significance Determination After Mitigation: Less than significant impact. (e) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.
Tribal consultation efforts pursuant to AB 52 to identify additional significant TCRs meeting the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1 was initiated by the City of Orange on June 29, 2022. City staff sent notification letters pursuant to AB 52 to four tribes, Gabrieliño/Tongva Nation, Gabrieleño Band of Mission Indians–Kizh Nation, Torres Martinez Desert Cahuilla Indians, and San Gabriel Band of Mission Indians. Subsequently, a consultation between City staff and the Gabrieleño Band of Mission Indians–Kizh Nation occurred on September 6, 2022. As a result of the consultation, MM TCR-1, MM TCR-2, and MM TCR-3 are required to mitigate impacts to tribal cultural resources to less than significant. MM TCR-1 requires a Native American Monitor to be retained prior to the commencement of any grounddisturbing activities. MM TCR-2 outlines the procedure in the event that human remains or funerary objects are discovered. MM TCR-3 outlines the procedures for burials and funerary remains. With implementation of MM TCR-1, MM TCR-2, and MM TCR-3, impacts would be less than significant.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM TCR-2, and MM TCR-3.
MM TCR-1 Retain a Native American Monitor Prior to Commencement of GroundDisturbing Activities A. The project applicant/lead agency shall retain a Native American Monitor from or approved by the Gabrieleno Band of Mission Indians - Kizh Nation. The monitor shall be retained prior to the commencement of any "ground-disturbing activity" for the subject project at all project locations (i.e., both on-site and any off-site locations that are included in the project description/definition and/or required in connection with the project, such as public improvement work). "Ground disturbing activity" shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching.
B. A copy of the executed monitoring agreement shall be submitted to the lead agency prior to the earlier of the commencement of any ground-disturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity.
C. The monitor will complete daily monitoring logs that will provide descriptions of the relevant ground-disturbing activities, the type of construction activities performed, locations of ground disturbing activities, soil types, cultural-related materials, and any 84 other facts, conditions, materials, or discoveries of significance to the Tribe. Monitor logs will identify and describe any discovered TCRs, including but not limited to, Native American cultural and historical artifacts, remains, places of significance, etc., (collectively, tribal cultural resources, or ''TCR"), as well as any discovered Native American (ancestral) human remains and burial goods. Copies of monitor logs will be provided to the project applicant/lead agency upon written request to the Tribe.
D. On-site tribal monitoring shall conclude upon the latter of the following (1) written confirmation to the Kizh from a designated point of contact for the project applicant/lead agency that all ground-disturbing activities and phases that may involve ground-disturbing activities on the project site or in connection with the project are complete; or (2) a determination and written notification by the Kizh to the project applicant/lead agency that no future, planned construction activity and/ordevelopment/construction phase at the project site possesses the potential to impact Kizh TCRs.
E. Upon discovery of any TCRs, all construction activities in the immediate vicinity of the discovery shall cease (i.e., not less than the surrounding 50 feet) and shall not resume until the discovered TCR has been fully assessed by the Kizh monitor and/or Kizh archaeologist. The Kizh will recover and retain all discovered TCRs in the form and/or manner the Tribe deems appropriate, in the Tribe's sole discretion, and for any purpose the Tribe deems appropriate, including for educational, cultural and/or historic purposes.

Impact Analysis
(a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation?
A discussion of the proposed project’s energy use is presented below. Energy use consumed by the proposed project was estimated and includes natural gas, electricity, and fuel consumption for the proposed project construction and operation. Energy calculations are included as part of Appendix D.
Note that the analysis evaluates a construction start date of December 2022. Extending the construction schedule by a year would ultimately reduce any potential impacts as CalEEMod presumes that future construction equipment would become more efficient. Furthermore, the analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Due to the reduction in building square footage on the proposed site, the project emissions related to both construction and operational activity would be lower than what is analyzed herein. Thus, this conservative analysis evaluates the worst-case scenario.
Construction Impacts
The construction schedule is anticipated to begin in December 2022 and conclude in June 2024. If the construction schedule moves to later years, construction fuel consumption may decrease because of improvements in technology and more stringent regulatory requirements as older, less fuel-efficient equipment is gradually replaced by newer and more fuel-efficient equipment. The proposed project would require demolition, site preparation, grading, building construction, architectural coating, and paving activities. Construction would require energy for the manufacture and transportation of building materials, preparation of the site (e.g., demolition, site clearing, and grading), and the actual construction of the building. Petroleum-based fuels such as diesel fuel and gasoline would be the primary sources of energy for these tasks.
The types of on-site equipment used during construction of the proposed project could include gasoline- and diesel-powered construction and transportation equipment, including trucks, bulldozers, frontend loaders, forklifts, and cranes. Construction equipment is estimated to consume a total of 23,954 gallons of diesel fuel over the entire construction duration (Appendix D). 86 Fuel use associated with construction vehicle trips generated by the proposed project was also estimated; trips include construction worker trips, haul truck trips for material transport, and vendor trips for construction material deliveries. Fuel use from these vehicles traveling to the project site was based on (1) the projected number of trips the proposed project would generate during construction, (2) average trip distances by trip type, and (3) fuel efficiencies estimated in the ARB Emissions Factors (EMFAC) mobile source emission model. The specific parameters used to estimate fuel usage are included in Appendix D. In total, the proposed project is estimated to generate 1,303,482 Vehicle Miles Traveled (VMT) and a combined 54,665 gallons of gasoline and diesel for vehicle travel during construction.
Other equipment could include office trailers. Singlewide mobile office trailers, which are commonly used in construction staging areas, generally range in size from 160 square feet to 720 square feet. A typical 720-square-foot office trailer would consume approximately 15,068 kilowatt-hours (kWh) during the 1.5-year construction schedule (Appendix D).
The overall construction schedule and process is already designed to be efficient in order to avoid excess monetary costs. For example, equipment and fuel are not typically used wastefully due to the added expense associated with renting the equipment, maintaining it, and fueling it. Therefore, the opportunities for future efficiency gains during construction are limited.
Operational Impacts
The proposed project would consume energy as part of building operations and transportation activities. Project energy consumption is summarized in Table 12. Energy consumed by the operation of the existing land uses on the project site are not presented here. Existing operational energy demand would be generated through the use of natural gas for space and water heating and appliance operation, the use of electricity for building and space lighting and operation of electrified building components such as elevators, and the use of vehicle fuel by the existing facility’s employees and patrons traveling to and from the project site. Therefore, energy consumption presented in Table 12 represents a conservative assessment of energy demand generated by the proposed project.

1 Operational Fuel Consumption based on EMFAC2014 Emissions Inventory, Vehicle Classification (Fleet Mix) EMFAC2007 Categories. The calculations are for the year 2023 when the project will be operational and for Orange County, where the project is located (Appendix D).
Operation of the proposed project would consume an estimated 2,153,163 kWh of electricity and an estimated 2,725,300 kilo-British Thermal Unit (kBTU) of natural gas on an annual basis. The proposed project’s buildings would be designed and constructed in accordance with the City’s latest adopted energy efficiency standards, which are based on the State’s Building Energy Efficiency Standards. These are widely regarded as the most advanced building energy efficiency standards and compliance would ensure that building energy consumption would not be wasteful, inefficient, or unnecessary.
Project-related vehicle trips would consume an estimated 197,865 gallons of gasoline and diesel annually. The proposed project is located in an urbanized area of the City of Orange and would introduce high-density residential units close to jobs, amenities, and services. The project site would be developed to facilitate pedestrian connectivity to adjacent land uses and would provide bicycle parking.
Regional access is provided via SR-22, which is approximately 0.2 mile from the project site. In addition, the project site is less than 0.1 mile from the Garden Grove-Memory, Garden Grove-The City, and The City-Park Central bus stops for various OCTA bus routes. Thus, transportation fuel consumption would not be wasteful, inefficient, or unnecessary. Impacts would be less than significant.
Conclusion
As discussed in this analysis, the proposed project’s combined construction and annual operational energy uses would not result in potentially significant environmental impacts due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation. Thus, the proposed project’s construction and operational energy use would result in a less than significant impact on the environment.
88 Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Conflict with or obstruct a State of local plan for renewable energy or energy efficiency? The proposed project would be served with gas provided by Southern California Gas (SoCalGas).
SoCalGas has set a voluntary goal to reduce their own electricity usage. Their energy conservation program seeks to (1) reduce greenhouse gas (GHG) emissions, (2) advance new technologies in energy efficiency and emerging, renewable energy, and (3) lower estimated electricity consumption at company facilities through comprehensive energy efficiency retrofits and incorporation of energy-efficient measures into new construction.37 Therefore, the proposed project would be served by a gas company that strives for increased use of renewable energy sources and energy conservation.
The proposed project would be served with electricity provided by SCE, which was required to meet California’s renewable portfolio standard (RPS) of 33 percent by 2020. SCE’s 2019 power mix included 35.1 percent eligible renewable (biomass and waste, geothermal, eligible hydroelectric, solar, and wind), 7.9 percent large hydroelectric, 16.1 percent natural gas, 8.2 percent nuclear and 32.6 percent unspecified sources of power. 38 SCE also offers the SCE Green Rate 50 Percent option, which includes 67.5 percent eligible renewable (geothermal, solar, and wind), 4 percent large hydroelectric, 8.1 percent natural gas, 4.1 percent nuclear and 16.3 percent unspecified sources of power, and the SCE Green Rate 100 Percent option, which includes 100 percent eligible renewable (solar).39 SCE would be required to meet California’s RPS of 60 percent by 2030 and carbon-free electricity by 2045.
The proposed project would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential and Nonresidential Buildings as applicable. These standards include minimum energy efficiency requirements related to building envelope, mechanical systems (e.g., heating, ventilation, and air conditioning [HVAC] and water heating systems), and indoor and outdoor lighting. The incorporation of the Title 24 standards into the design of the proposed project would ensure that the proposed project would not result in the use of energy in a wasteful manner.
City of Orange General Plan Energy Policies
The General Plan contains several policies which intend to improve energy efficiency in the design and operation of new development that apply to the proposed project. For instance, Policy 3.4 of the Infrastructure Element encourages energy efficiency streetlights, Policy 2.6 of the Natural Resources Element encourages sustainable building and site design in new construction, and 37 Southern California Gas Company (SoCalGas). 2021. Sustainability at SoCalGas. Website:
https://www.socalgas.com/ko/taxonomy/term/731. Accessed August 18, 2022. 38 Southern California Edison (SCE). 2020. 2019 Power Content Label. Website: https://www.sce.com/sites/default/files/inlinefiles/SCE_2019PowerContentLabel.pdf. Accessed August 18, 2022. 39 Ibid. 89 Policy 3.3 of the Circulation and Mobility Element encourages the incorporation of transit-oriented design in new development.
The proposed project includes several design features that would conserve energy and demonstrate consistency with the General Plan's energy efficiency objectives. As previously discussed, the proposed project would be designed and constructed to the latest energy efficiency building standards and Title 24 requirements. The proposed project would include a pedestrian-friendly design including a widened sidewalk and streetlights for pedestrians. The project site is connected via pedestrian facilities to the Santa Ana River Trail and Bikeway, approximately 350 feet west of the project site, which is a multiuse paved trail that runs parallel to the Santa Ana River and will run 110 miles when finished.40 The proposed project would further provide bicycle parking and connectivity to the public sidewalk system, transit stops, nearby employment and shopping centers, schools, parks, and other parcels for ease of pedestrian and cyclist access.
The proposed project would comply with existing State energy standards and with energy conservation policies contained in the General Plan. As such, the proposed project would not conflict with State or local renewable or energy efficiency objectives. Impacts would be less than significant.
Conclusion
As illustrated in this analysis, implementation of the proposed project would not conflict with the reduction measures proposed in California’s RPS, California’s Energy Efficiency Standards, or Title 24 building construction standards. In addition, the proposed project would not conflict with the energy efficiency objectives of the General Plan. In summary, the proposed project would not conflict with any State or local plan for renewable energy or energy efficiency. The impact would be less than significant.

Additionally, a Paleontological Records Search was conducted at the Natural History Museum of Los Angeles County on September 26, 2020.
These documents are included as Appendix E-1 and Appendix E-2 of this IS/MND. Note that the Paleontological Records Search is based on a larger study area than what is currently proposed.
The Paleontological Records Search includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Thus, this conservative analysis evaluates the worst-case scenario. 91 Impact Analysis
(a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving:
(i) Rupture of a known earthquake fault, as delineated on the most recent AlquistPriolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.
According to the General Plan Public Safety Element, there are no known Alquist-Priolo Earthquake Fault zones in the City of Orange.41 As such, the project site is not located within an Alquist-Priolo Earthquake Fault Zone. There are the two faults in the City of Orange that are not part of the Alquist-Priolo Earthquake Fault. These include the Peralta Hills Fault and the El Modena Fault. Both the Peralta Hills Fault and the El Modena Fault are classified as possibly active by the Southern California Earthquake Data Center. However, according to the General Plan, displacements along these two faults are smaller than those along the more prominent regional faults, and the maximum probable earthquake magnitudes would be much less than those along the regional faults. Therefore, the project site is not at risk of fault rupture.42 According to the Due Diligence Geotechnical Engineering Evaluation, no known active or potentially active faults have been mapped across the project site, and the site is not located within a designated Alquist-Priolo Earthquake Fault Zone.
43 The nearest active faults with surface
expression to the site are the Newport-Inglewood and Whittier fault zones located 9 miles and 10.2 miles from the site, respectively. The San Andreas fault, which is considered the largest active fault in California, is located approximately 42 miles northeast of the project site. Therefore, the risk of ground rupture is considered low, and no impact would occur. (ii) Strong seismic ground shaking?
The principal seismic hazard to the site is ground shaking resulting from an earthquake occurring along any of several major active and potentially active faults in Southern California. The intensity of ground shaking at a given location depends primarily upon the earthquake magnitude, the distance from the source, and the site response characteristics.44 According to the General Plan Public Safety Element, there are no known Alquist-Priolo Fault Zones located in the City of Orange.45 However, as with any project that is located in Southern California, the project site is located in a seismically active region and may be exposed to strong 41 City of Orange. 2010.

July 18. 44 Ibid. 45 Ibid. 92 ground shaking during a seismic event. The proposed project would comply with the latest edition of the California Building Standards Code (CBC), which includes seismic design parameters. The proposed project would be designed in accordance with all applicable current codes and standards utilizing the appropriate seismic design parameters to reduce seismic risk as defined by California Geological Survey (CGS) Chapter 2 of Special Publication 117a,46 as recommended in the Due Diligence Geotechnical Engineering Evaluation prepared for the project by Leighton and Associates, Inc.47 Compliance with seismic design standards would ensure that the risk of loss, injury, or death from strong ground shaking is not exacerbated by the proposed project.
Additionally, implementation of the preliminary geotechnical recommendations, as required by MM GEO-1, would reduce potential impacts related to strong seismic ground shaking. Therefore, potentially significant impacts would be less than significant with mitigation incorporated. (iii) Seismic-related ground failure, including liquefaction? Liquefaction is a seismic phenomenon in which loose, saturated, fine-grained granular soils behave similarly to a fluid when subjected to high-intensity ground shaking. Liquefaction occurs when three general conditions exist: (1) shallow groundwater; (2) low density, fine, clean sandy soils; and (3) high-intensity ground motion. Studies indicate that saturated, loose and medium dense, near-surface cohesionless soils exhibit the highest liquefaction potential.48 The General Plan Safety Element indicates that the project site is within an area of the City that is prone to liquefaction.49 Additionally, according to the Due Diligence Geotechnical Engineering Evaluation, the project site is located within a liquefaction hazard area. Based on the results of a site-specific liquefaction analysis, the potential for liquefaction at the site is moderate.50 The proposed project would be required to comply with the latest adopted edition of the CBC, which includes engineering design standards to reduce potential seismic risks. Additionally, MM GEO-1 requires compliance with seismic design standards and all preliminary geotechnical recommendations from the Due Diligence Geotechnical Engineering Evaluation. Implementation of GEO-1 includes ground improvements measures within the structural influence the residential complex and application of remedial grading methodology below the parking structures. This mitigation would ensure that the proposed project would not create a risk of loss, injury, or death from seismic-related ground failure and liquefaction. Therefore, potentially significant impacts would be less than significant with mitigation incorporated. 46 California Geological Survey (CGS, previously known as the California Division of Mines and Geology). 2008.

The General Plan Safety Element indicates areas of the City that are prone to landslides.51 According to the Safety Element, the project site is not located within a landslide hazard area.
Additionally, the Due Diligence Geotechnical Engineering Evaluation determined that the project site is within a relatively flat alluvial plane; therefore, the potential for the landslides to occur at the project site would be considered low. Further, the Environmental Geology of Orange County Map52 depicts no landslides on the site or within the surrounding area. Therefore, there would be no impact related to landslides.
Significance Determination: Potentially significant impact for rupture of a known fault, strong seismic ground shaking, and seismic-related ground failure. No impact for landslides.
Mitigation Measures:
MM GEO-1 Implement the preliminary geotechnical recommendations pertaining to site grading, preliminary foundation design, slabs-on-grade, temporary excavation and shoring design, drainage and landscaping, ground improvement, and future geotechnical exploration, as outlined on page 17 through page 24 of the Due Diligence Geotechnical Engineering Evaluation.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated for rupture of a known fault, strong seismic ground shaking, and seismicrelated ground failure. No impact for landslides. (b) Result in substantial soil erosion or the loss of topsoil? The Due Diligence Geotechnical Engineering Evaluation determined that no topsoil occurs on the project site due to the history of earthwork grading since the early 1970s. The topsoil has been mixed with underlying alluvium soil and incorporated into an existing blanket of engineered fill that presently underlies existing improvements, which could result in runoff and erosion when disturbed.53 Construction of the proposed project would include activities such as grading and earthmoving activities that could potentially result in erosion during the construction phase.
Grading that would occur on-site would comply with the City’s grading ordinance, which regulates grading and earthwork to control erosion and runoff, which would limit potential impacts related to soil erosion and loss of topsoil.54
As discussed in greater detail in Section 5.10, Hydrology and Water Quality, the proposed project would be subject to the National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (Construction General Permit). The proposed project would be required to submit a Storm Water 51 Leighton and Associates, Inc. 2021. Due Diligence Geotechnical Exploration Report.

https://library.qcode.us/lib/orange_ca/pub/municipal_code/item/title_16-chapter_16_40. Accessed August 18, 2022. 94 Pollution Prevention Plan (SWPPP). The SWPPP would identify the sources of sediment and other pollutants that could affect the quality of stormwater discharges and describe and ensure the implementation of BMPs to reduce or eliminate sediment and other pollutants in stormwater as well as non-stormwater discharges resulting from construction activity. Compliance with the City’s grading ordinance and the SWPPP would ensure that the project does not result in substantial soil erosion and loss of topsoil. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse?
Seismically induced landslide
The project site is not at risk of seismically induced landslides because there are no slopes or hillsides on or adjacent to the project site. The project site is not located within an area that has been identified by the State of California as being potentially susceptible to seismically induced landslides.55 Additionally, the proposed project is not anticipated to include the construction of engineered slopes. Therefore, there would be no impacts associated with landslides.
Seismically induced lateral spreading
Although the subsurface soils at the site are susceptible to liquefaction, the potential for development of lateral spreading and flow failure is considered low since the site is relatively flat and is not abutting an open-face or outboard slope, and actual groundwater was measured below a depth of 32 feet below the surface. Therefore, impacts associated with seismically induced lateral spreading would be less than significant.
Seismically induced settlement
The project site may be subject to seismically induced settlement.56 Seismically induced settlement consists of dry dynamic settlement (above groundwater) and liquefaction-induced settlement (below groundwater). These settlements occur primarily within loose to moderately dense sandy soil due to reduction in volume during and shortly after an earthquake event.57 Pursuant to the Due Diligence Geotechnical Engineering Evaluation, compliance with the recommended remedial earthwork at the site and with standard structural design requirements from the current building code would reduce potential impacts relating to seismically induced settlement.58 MM GEO-1 would require implementation of the remedial earthwork recommendations as outlined in the Due 55 Leighton and Associates, Inc. 2021. Due Diligence Geotechnical Exploration Report, Figure 5, Seismic Hazard Map. August 17. 56 Leighton and Associates, Inc. 2021. Due Diligence Geotechnical Exploration Report. August 17. 57 Ibid. 58 Ibid. 95 Diligence Geotechnical Engineering Evaluation. Therefore, potentially significant impacts would be less than significant with mitigation incorporated.
Liquefaction or collapse
As discussed in Impact 5.7a(iii) above, the project site is located within a liquefaction hazard area.
The proposed project would be required to comply with the latest adopted edition of the CBC, which includes engineering design standards to reduce potential seismic risks. Additionally, compliance with seismic design standards would ensure that the proposed project would not create a risk of loss, injury, or death from seismic-related ground failure and liquefaction. Implementation of MM GEO-1 would reduce impacts associated with liquefaction to less than significant.
Therefore, potentially significant impacts would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact for seismically induced settlement, and liquefaction or collapse. Less than significant impact for lateral spreading.
No impact for seismically induced landslide.
Mitigation Measures: Implementation of MM GEO-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated for seismically induced settlement, and liquefaction or collapse. Less than significant impact for lateral spreading. No impact for seismically induced landslide. (d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? The Due Diligence Geotechnical Engineering Evaluation found that the upper 15 feet of the site consist of a non-cohesive silty sand that is assumed to be non-expansive. The expansive potential of clayey earth materials anticipated at basement subgrade in the residential complex area would be tested to verify conformance with the project design plans. 59 Additionally, the California
Department of Mines and Geology has documented the area as having generally low soil expansiveness.60 Therefore, the project site is not located on expansive soil and would not cause direct or indirect risks to life or property. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?
The proposed project would connect to the City’s existing wastewater service. The proposed project would not utilize septic tanks or any other alternative method of wastewater disposal or 59 Leighton and Associates, Inc. 2021. Due Diligence Geotechnical Exploration Report. August 17. 60 California Department of Mines and Geology. 1976. Open-File Report 79-8 LA, Environmental Geology of Orange County, California. 96 conveyance. This condition precludes the possibility that the proposed project would have impacts related to septic tanks or an alternative wastewater disposal system. Therefore, there would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
A significant adverse effect could occur if grading or excavation activities associated with a project would disturb paleontological resources or geologic features, if any exist within the project site.
Paleontological resources include fossil remains, fossil localities, and formations that have produced fossil material in other nearby areas. Paleontological resources are limited, nonrenewable, sensitive scientific and educational resources, including fossils preserved either as impressions of soft (fleshy) or hard (skeletal) parts, mineralized remains of skeletons, tracks, or burrows; other trace fossils; coprolites (fossilized excrement); seeds or pollen; and other microfossils from terrestrial, aquatic, or aerial organisms.
As discussed in the City of Orange General Plan EIR, the County of Orange General Plan has designated most of the planning area generally east of SR-55 as an area of paleontological resource sensitivity. Sensitivity levels are predicated primarily on the underlying geological formations.61 According to the Paleontological Records Search conducted for the proposed project, there are no recorded fossils that lie directly within the project site. However, there are known fossil sites near the project site from the same sedimentary deposits that occur on the project site. Therefore, there is potential for the presence of subsurface paleontological resources on the project site and could be encountered during ground-disturbing activities the site.
MM GEO-2 would require paleontological monitoring on the project site and proper documentation and recordation in the event that paleontological resources are found as part of project construction activities. Implementation of MM CUL-2 would reduce impacts to any paleontological resources that are inadvertently discovered. The proposed project’s potentially significant impact to paleontological resources would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM GEO-2 A Paleontological Resources Monitor shall be present during all project excavations that occur 10 feet or more below ground surface. In the event that fossils or fossilbearing deposits are discovered during construction activities, excavations within a 61 City of Orange. 2010. General Plan Environmental Impact Report. March.

(a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
(b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Environmental Setting
The project site is located within the jurisdiction of the SCAQMD. Note that the analysis evaluates a construction start date of December 2022. Extending the construction schedule by a year would ultimately reduce any potential impacts as CalEEMod presumes that future construction equipment would become more efficient. Furthermore, the analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Due to the reduction in building square footage on the proposed site, the project emissions related to both construction and operational activity would be lower than what is analyzed herein. Thus, this conservative analysis evaluates the worst-case scenario.
Thresholds of Significance
In October 2008, the SCAQMD released a Draft Guidance Document—Interim CEQA Greenhouse Gas Significance Threshold (Draft Guidance Document) that recommended a tiered approach to analyzing GHG emissions in a project-level analysis.62 In the Draft Guidance Document, the SCAQMD provided numerical thresholds that can be applied to smaller projects (such as the proposed project). The applicable interim GHG thresholds presented in the Draft Guidance Document are:
• Industrial Projects—10,000 metric tons (MT) of carbon dioxide equivalents (CO2e) per year.
• Residential, Commercial, and Mixed-Use Projects (including industrial parks, warehouses, etc.)—3,000 MT CO2e per year.
The City of Orange has not adopted its own GHG thresholds, nor has the City prepared a Climate Action Plan (CAP) that can be used as a basis for determining project significance. Therefore, the applicable numerical threshold presented above is utilized in this analysis to determine whether the proposed project would have a significant impact related to GHG emissions. Because the proposed project is a mixed-use project, the applicable GHG significance threshold is 3,000 MT CO2e. If the proposed project would generate GHG emissions below the threshold, it is acceptable 62 South Coast Air Quality Management District (SCAQMD). 2008. Draft Guidance Document – Interim CEQA Greenhouse Gas (GHG) Significance Threshold. October.

Accessed August 18, 2022. 99 to conclude that the proposed project’s GHG contribution would not be “cumulatively considerable” and would therefore be “less than significant” under CEQA.
Impact Analysis
(a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
Construction Emissions
The proposed project would generate GHG emissions during construction activities resulting from emission sources such as construction equipment, haul trucks, and construction worker vehicles.
Although these emissions would be temporary and short-term in nature, they could represent a substantial contribution of GHG emissions. Construction emissions were modeled using CalEEMod Version 2016.3.2. See Appendix A for detailed modeling parameters and assumptions.
Table 13 presents the proposed project’s total construction emissions, which are amortized over the assumed lifetime of 30-years following the guidance from the SCAQMD. The amortized construction emissions are then added with annual operational emissions to provide a total estimate of the project’s GHG emissions.

Source: Appendix A
Operational Emissions
Operational or long-term emissions occur over the life of the proposed project. Sources for operational emissions include:
• Motor Vehicles: These emissions refer to GHG emissions contained in the exhaust from the cars and trucks that would travel to and from the project site. • Natural Gas: These emissions refer to the GHG emissions that occur when natural gas is burned on the project site. Natural gas uses could include heating water, space heating, dryers, stoves, or other uses.
• Indirect Electricity: These emissions refer to those generated by off-site power plants to supply electricity required for the project.
• Area Sources: These emissions refer to those produced during activities such as landscape maintenance.
• Water Transport: These emissions refer to those generated by the electricity required to transport and treat the water to be used on the project site. • Waste: These emissions refer to the GHG emissions produced by decomposing waste generated by the project.
Table 14 presents the estimated annual GHG emissions from the proposed project’s operational activities as well as the GHG emissions generated by the existing land uses on the project site. As shown in Table 14, the proposed project would generate approximately 2,318 net MT CO2e per year after the inclusion of 35 MT CO2e per year from project construction and accounting for the reductions in operational GHG emissions from existing land uses.

Conclusion
As shown in Table 14, the proposed project’s combined amortized construction and annual operational GHG emissions would not exceed the applicable threshold of significance of 3,000 MT CO2e per year. Thus, the proposed project’s construction and operational GHG emissions would result in less than significant impacts.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
The City of Orange has not adopted a GHG reduction plan. In addition, the City has not completed the GHG inventory, benchmarking, and goal-setting process required to identify a reduction target and to take advantage of the streamlining provisions contained in the CEQA Guidelines amendments adopted for Senate Bill (SB) 97. Since no other local or regional CAP is in place, the proposed project is assessed for its consistency with the ARB’s adopted 2017 Scoping Plan Update.
This would be achieved with an assessment of the proposed project’s compliance with Scoping Plan measures. Although the General Plan does not specifically meet the requirements for a local plan to reduce GHG emissions, it contains policies intended to reduce vehicle travel and energy use that would provide GHG reductions. Therefore, the proposed project’s consistency with the General Plan policies is also assessed.
SB 32 2017 Scoping Plan Update
The 2017 Climate Change Scoping Plan Update addressing the SB 32 targets were adopted on December 14, 2017. Originally, AB 32, the California Global Warming Solutions Act of 2006, was passed to reduce GHG emissions to 1990 levels by 2020. SB 32 extends and expands upon AB 32 by mandating that GHG emissions are reduced to 40 percent below 1990 levels by 2030. Table 15 102
provides an analysis of the proposed project’s consistency with the 2017 Scoping Plan Update measures. As shown in Table 15, many of the measures are not applicable to the proposed project, however, the proposed project is consistent with strategies that are applicable.
Table 15: Consistency with SB 32 2017 Scoping Plan Update 2017 Scoping Plan Update Reduction Measure Project Consistency SB 350 50 percent Renewable Mandate. Utilities
subject to the legislation will be required to increase their renewable energy mix from 33 percent in 2020 to
50 percent in 2030.
Not applicable. This measure would apply to utilities and not to individual development projects. The proposed
project would purchase electricity from a utility subject to the SB 350 Renewable Mandate.
SB 350 Double Building Energy Efficiency by 2030.
This is equivalent to a 20 percent reduction from 2014
building energy usage compared to current projected
2030 levels.
Not applicable. This measure applies to existing buildings.
New structures are required to comply with Title 24 Energy Efficiency Standards that are expected to increase in
stringency over time. The proposed project would comply with the applicable Title 24 Energy Efficiency Standards in effect at the time building permits are received.
Low Carbon Fuel Standard. This measure requires
fuel providers to meet an 18 percent reduction in
carbon content by 2030.
Not applicable. This is a Statewide measure that cannot be implemented by a project applicant or lead agency.
However, vehicles accessing the proposed residential and retail buildings at the project site would be benefit from the standards.
Mobile Source Strategy (Cleaner Technology and
Fuels Scenario). Vehicle manufacturers will be
required to meet existing regulations mandated by the
LEV III and Heavy-Duty Vehicle programs. The
strategy includes a goal of having 4.2 million ZeroEmission Vehicles (ZEVs) on the road by 2030 and increasing numbers of ZEV trucks and buses.
Not applicable. This measure is not applicable to the
proposed project; however, vehicles accessing the proposed residential and retail buildings at the project site would be benefit from the increased availability of cleaner technology and fuels. Future residents and visitors can be expected to purchase increasing numbers of more fuel-efficient and
zero-emission cars and trucks each year. Furthermore,
delivery trucks and buses that would serve future residents will be made and thus increase the numbers of ZEV delivery trucks and buses.
Sustainable Freight Action Plan The plan’s target is
to improve freight system efficiency 25 percent by
increasing the value of goods and services produced
from the freight sector, relative to the amount of carbon that it produces by 2030. This would be achieved by
deploying over 100,000 freight vehicles and equipment
capable of zero-emission operation and maximize near
zero-emission freight vehicles and equipment powered
by renewable energy by 2030.
Not applicable. This measure applies to owners and
operators of trucks and freight operations. The proposed project is mixed-use in nature and would not support truck and freight operations. It is expected that deliveries
throughout the State would be made with an increasing
number of ZEV delivery trucks, including deliveries that would be made to future residents and to the future retail establishments at the project site.
Short-Lived Climate Pollutant (SLCP) Reduction
Strategy. The strategy requires the reduction of SLCPs
by 40 percent from 2013 levels by 2030 and the
reduction of black carbon by 50 percent from 2013
levels by 2030.
Consistent. Consistent with SCAQMD Rule 445—Wood
Burning Devices, no woodburning devices are proposed as part of the proposed project. Natural gas hearths produce very little black carbon compared to woodburning
fireplaces; therefore, the proposed project would not include major sources of black carbon.

Furthermore, the proposed project is not within an SCS
priority area.
Post-2020 Cap-and-Trade Program. The Post 2020
Cap-and-Trade Program continues the existing
program for another 10 years. The Cap-and-Trade
Program applies to large industrial sources such as
power plants, refineries, and cement manufacturers.
Not applicable. The proposed project is not one targeted by the cap-and-trade system regulations, and, therefore, this measure does not apply to the proposed project. However, the post-2020 Cap-and-Trade Program indirectly affects
people and entities who use the products and services
produced by the regulated industrial sources when increased cost of products or services (such as electricity and fuel) are transferred to the consumers.
Natural and Working Lands Action Plan. The ARB
is working in coordination with several other agencies
at the federal, State, and local levels, stakeholders, and with the public, to develop measures as outlined in the Scoping Plan Update and the governor’s Executive
Order B-30-15 to reduce GHG emissions and to
cultivate net carbon sequestration potential for
California’s natural and working land.
Not applicable. The proposed project is mixed-use
development in a built-up urban area and would not be
considered natural or working lands.

As demonstrated in Table 16 above, the proposed project is consistent with the applicable climate change related policies contained within the General Plan.
Conclusion
As shown in Table 15, implementation of the proposed project would not conflict with the reduction measures proposed in SB 32. In addition, the proposed project would not conflict with the General Plan as shown in Table 16. In summary, the proposed plan would not conflict with any applicable plan, policy, or regulation adopted to reduce the emissions of GHGs. Nor would the proposed project’s combined amortized construction and annual operational GHG emissions exceed the applicable threshold of 3,000 MT CO2e per year. Considering this information, the 106
proposed plan would not conflict with any applicable plan, policy or regulation of an agency adopted to reduce the emissions of GHGs; impacts would be less than significant.

The information in this section is based, in part, on a Phase I Environmental Site Assessment (Phase I ESA) prepared for the residential site at 840 The City Drive South dated July 18, 2019 and a Phase I ESA for the parking garage site located at 790 The City Drive South dated January 27, 2021 both prepared by Leighton and Associates, Inc., and an Indoor Air Quality Assessment prepared by SCS Engineers dated January 16, 2019. These reports are included as Appendix F-1, , Appendix F-2, and Appendix F-4 of this IS/MND. The findings of the Phase I ESAs are based on the results of a site visit, records review, and interviews. The purpose of the Phase I ESAs were to identify evidence of Recognized Environmental Conditions (RECs),63 Historical RECs (HRECs),64 or Controlled RECs (CRECs)65 in connection with the project site. Note that the Phase I ESA for the parking garage site dated January 27, 2021, prepared by Leighton and Associates, Inc., is based on a larger study area than what is currently proposed. The analysis includes the 63 RECs are defined, according to ASTM E1527-13 as, “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not RECs.” 64 HRECs are defined, according to ASTM E1527-13, as, “a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls.” 65 CRECs are defined, according to ASTM E1527-13, as, “a REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority, with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls.” 108
build-out of a stand-alone parking structure previously contemplated in the northern portion of the
5.86-acre site, which is no longer part of the proposed project. Thus, this conservative analysis evaluates the worst-case scenario.
Impact Analysis
(a) Create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials?
A significant impact may occur if a project would involve the use or disposal of hazardous materials as part of its routine operations or would generate toxic or otherwise hazardous emissions that could adversely affect sensitive receptors.
According to the General Plan Safety Element, the City follows the County’s Hazardous Materials Inspection and Enforcement Plan. To prevent accidents and ensure proper handling, routine inspections are conducted at businesses within the City that store, use, or handle hazardous materials. The City concentrates production of hazardous materials within its industrial area, separated from residential areas, educational uses, and institutional facilities. The City also identifies businesses transporting, manufacturing, using, and storing hazardous chemicals, and requires such businesses to exercise caution and to mitigate potential negative effects on surrounding land uses prior to obtaining businesses licenses. Periodic assessment and analysis of potential threats related to hazardous materials will result in proper response to hazardous substance emergencies. In addition, plans for residential or for mixed-use projects on industrial or commercial lands will be required to undergo proper site assessment and remediation prior to development.66
The project site is currently developed with a commercial building. The proposed project would include demolition and construction activities that would include the presence of small quantities of hazardous materials, such as paint, diesel fuel, lubricants, gasoline, and other petroleum-based products used to operate and maintain construction equipment and vehicles. However, the use of these materials would be temporary and would coincide with the short-term construction phase of the project. Additionally, the amounts of hazardous materials would be typical of construction projects and would be limited to the amounts needed for construction of the proposed project.
Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations. These include California Code of Regulations Title 22 Division 4.5 for appropriate management of hazardous materials, as well as the requirements of the United States Environmental Protection Agency (EPA), Resource Conservation and Recovery Act (RCRA), California Department of Toxic Substances Control (DTSC), California Division of Occupational Safety and Health (Cal/OSHA), and Caltrans. Compliance with the applicable hazardous material laws and regulations would ensure that the proposed project would not create a hazard to the public or the environment through 66 City of Orange. 2010. Orange General Plan – Public Safety Element. Website:

transport, use, or disposal of hazardous materials. Therefore, construction impacts would be less than significant.
During the operational phase of the proposed project, hazardous materials may be handled on the project site. Hazardous materials that would likely be used during operation would likely be limited to fertilizers, herbicides, pesticides, solvents, household cleaning agents, and similar materials used for maintenance and operation of the apartments, apartment building facilities, amenities, and landscaping. These types of materials are common and represent a low risk to people and the environment when used as intended. Therefore, impacts associated with hazardous materials would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?
Transport, use, and disposal of hazardous materials during construction and operation of the proposed project would comply with all applicable federal, State, and local policies, regulations, and ordinances set forth by the EPA, DTSC, Cal/OSHA, Caltrans, RCRA, Orange County Health Care Agency (OCHCA), and the OCFA. These include the following:
• Health and Safety Codes Sections 25270.7, 25270.8, and 25507; • Vehicle Code Section 23112.5;
• Public Utilities Code Section 7673 (PUC General Orders No. 22-B, 161); • California Government Code Sections 51018, 8670.25.5(a); • Water Codes Sections 13271, 13272; and
• California Labor Code Section 6409.1(b)10.
Therefore, the proposed project would not result in a significant hazard to the public or the environment through accidental release of hazardous materials into the environment. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? A project-related significant adverse effect may occur if the project site is located within 0.25-mile of an existing or proposed school site, and would potentially release toxic emissions which would 110
pose a health hazard beyond regulatory thresholds. There are no schools within 0.25-mile of the project site. The nearest school to the project site is Riverdale Elementary School, located 0.33- mile southwest of the project site at 13222 Lewis Street in Garden Grove. The nearest school within the Orange Unified School District is Lampson Elementary School, located at 13321 Lampson Avenue in Garden Grove, 0.75-mile northwest of the project site. This condition precludes the possibility of emitting hazardous materials, substances, or waste within 0.25-mile of a school. Therefore, no impacts would occur.
Significance Determination: No impact
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (d) Be located on a site which is included on a list of hazardous materials sites complied pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
Residential Site
Based on a review of regulatory databases performed as part of the Phase I ESA, a dry cleaning service called Cecilia’s Cleaners was located at the residential portion of the project site from at least 1989 until 2012. Historical information indicates that the dry cleaners used tetrachloroethene (PCE) from at least 1989 through 1999. A release of PCE occurred at the project site and has affected soil and soil gas at the site. A 1999 soils investigation detected PCE in a soil sample collected on the site. Additional soil samples collected in 2014 and 2015 detected the presence of PCE in soils at the site. Vapor encroachment and intrusion associated with the release of PCE is considered a REC at the site.67
In 2017, the current property owner entered into a Voluntary Cleanup Agreement with the DTSC in November 2017 for assessing and remediating the PCE at the project site.
According to the Phase I ESA database search results, a Risk Assessment Report and Remedial Investigation Report were to be completed for the project site. The Health Risk Assessment that evaluated PCE was completed and included in the Indoor Air Quality Assessment on January 16, 2019. And consistent with the recommendation of the DTSC, as part of the Voluntary Cleanup Agreement, an Indoor Air Quality Assessment was prepared by SCS Engineers on January 16, 2019 (noted in the previous sentence), to assess the potential for vapor intrusion of PCE or its degradation products into the building from soil vapor associated with the former Cecilia’s Cleaners.
According to the Indoor Air Quality Assessment, the PCE levels that were detected during the assessment indicate that the chemical exposure does not exceed the level considered safe for longterm exposure. Additionally, the assessment indicated that subsurface soil and soil vapor sampling did not identify PCE at levels that would pose a significant risk to groundwater or result in a 67 Leighton and Associates, Inc. 2019. Phase I ESA, 840 The City Drive South. 111
significant risk of vapor intrusion. The Indoor Air Quality Assessment concluded that there is no significant risk to groundwater, that the former dry cleaning operation poses no significant risk of vapor intrusion, and that further investigation of soil, soil vapor, or groundwater at the project site is not recommended.
According to the Phase I ESA for the residential portion of the project site, there are no other concerns on this portion of the site, and there is no evidence of CRECs or HRECs.
According to the Indoor Air Quality Investigation Report (Appendix F-3 and Appendix F-4), a DTSC-approved workplan was prepared for the project site dated March 12, 2018, which concluded that PCE was not present in indoor air at concentrations above its residential or commercial/industrial DTSC-Recommended screening level (SL).
Twenty-nine VOCs were detected in indoor air samples, six of which (benzene, chloroform, 1,2- dichloroethane, carbon tetrachloride, naphthalene, and hexachlorobutadiene) were detected at concentrations exceeding either their respective residential or commercial/industrial DTSCRecommended SLs. Each of these six VOCs was also detected in ambient air (AA) samples also at concentrations exceeding the DTSC-Recommended SLs, indicating that the project site is not a source of these VOCs in indoor air.
Subsurface soil and soil vapor sampling did not identify PCE at levels that would pose a significant risk to groundwater, and there are no residuals of VOCs under the building that could pose a significant risk of vapor intrusion. Subsurface concentrations of PCE are low, limited in extent, and well defined. Soil vapor VOC concentrations over time show PCE concentrations are decreasing, suggesting that its presence is being removed by natural attenuation or diffusion.
In summary, the multiple lines of evidence discussed above have demonstrated that there is no significant risk to groundwater and the former dry cleaning operation poses no significant risk of vapor intrusion. Further investigation of soil, soil vapor, or groundwater at the project site was not recommended in the Indoor Air Quality Investigation Report.
Additionally, the Phase I ESA prepared for the residential site recommended observations to be made during future property development for areas of possible contamination, such as, but not limited to, the presence of underground facilities, buried debris, waste drums, and tanks, stained soil, or odorous soil pursuant to MM HAZ-1. Should such materials be encountered, further investigation and analysis would be necessary at that time.
Parking Garages
The Phase I ESA completed for the proposed stand-alone parking garage confirmed the findings that a release of PCE associated with Cecilia’s Cleaners occurred at the residential portion of the project site and has affected soil and soil gas in that area. No on-site RECs, CRECs, or HRECs or off-site RECs were identified pursuant to the Phase I ESA prepared for the stand-alone parking 112
garage site.
68 Pursuant to the Phase I ESA prepared for the stand-alone parking garage site, the City will review observations made during property development for areas of possible contamination, such as, but not limited to, the presence of underground facilities, buried debris, waste drums, and tanks, stained soil, or odorous soil as outlined in MM HAZ-1. Should such materials be encountered, further investigation and analysis would be necessary at that time.
Potentially significant impacts associated with hazardous materials would be less than significant with mitigation incorporated for both the residential and parking garage site.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM HAZ-1 During property development, the Owner/Developer shall retain a hazards specialist to conduct biweekly site visits to observe for areas of possible contamination, such as, but not limited to, the presence of underground facilities, buried debris, waste drums, and tanks, stained soil, or odorous soil. Should hazardous materials be encountered, further investigation and analysis shall be necessary as deemed appropriate by City staff and/or Orange County Health Care Agency (OCHCA). Documentation and site visit notes shall be provided to City staff for review.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area?
The project site is not located within 2 miles of a public airport or a public use airport. Additionally, the project site is not located within an airport land use plan. The nearest airports are the Fullerton Municipal Airport, located 8.3 miles northwest of the project site, and the John Wayne Airport, located 6.5 miles south of the project site. Thus, the project site is not located within an Airport Land Use Compatibility Plan (ALUCP) or within 2 miles of a public or public use airport.
Therefore, the proposed project would not have the potential to result in a safety hazard or excessive noise for people residing or working in the project area. There would be no impacts.
According to the General Plan Safety Element, the City complies with the Airport Land Use Commission (ALUC) for Orange County’s Heliports and Airport Environs Land Use Plan to ensure that future land uses located near helipads remain compatible. This plan requires that construction or alteration of structure in excess of 200 feet tall complies with federal and State law 68 Leighton and Associates, Inc. 2021. Phase I ESA, Proposed Parking Garages. January. 113
(FAR Part 77 and PUC 21676(b), respectively) and with the requirements of the ALUC for Orange County, as well as all applicable requirements of the City of Orange.
While there are no airports in proximity of the project site, several helipads exist in the area. The University of California, Irvine (UCI) Medical Center has an at-grade helipad at the southeast corner of Chapman Avenue and The City Drive, approximately 0.91 mile north of the project site.
Additionally, the Orange County Fire Training Facility has an at-grade helipad and is located approximately 1.47 miles to the northeast, at the Orangewood Avenue and Rampart Street intersection. A rooftop helipad is located 1.52 miles northeast of the site at the Children’s Hospital of Orange County, near the intersection of West La Veta Avenue and Main Street.
Because of the project site’s distance from these helipads, the proposed project is not anticipated to result in a change in air traffic patterns, and the proposed project would not result in a safety hazard for people residing or working on-site or in the area. There are also buildings of similar height to the proposed project that are located adjacent to and in the proximity of the helipads, as well as within the office complex surrounding the project site. Therefore, the height of the proposed building and structures would not interfere with helicopter operations at these helipads.
Additionally, while over congested areas, helicopters are required to maintain an altitude of at least 1,000 feet above the highest obstacle within 2,000 feet of the aircraft, except as needed for takeoff and landing (Code of Federal Regulations [CFR], Title 14, § 91.119). Furthermore, helicopter takeoffs and landings are at a sufficient enough distance from the project site so as to not pose a safety hazard to residents, workers, or guests within the project site or its surroundings. Therefore, there would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
The City has an Emergency Operations Plan (EOP) that establishes emergency preparedness and emergency response procedures for both peacetime and wartime disasters. The City’s EOP was prepared in accordance with the State Office of Emergency Services guidelines for multi-hazard functional planning. The plan consists of three parts: (1) a basic plan; (2) annexes the address specific functions and duties of response agencies; and (3) a directory of emergency response resources. Rather than focusing on specific responses for specific hazards, the City’s plan concentrates on specific agency response for any type of disaster. For example, in the event of an 114
earthquake, flood, or industrial accident, the Orange City Fire Department (OCFD) is responsible for fire suppression, emergency medical care, and rescue operations.69 According to the General Plan Public Safety Element, all City arterials are recognized as primary emergency response routes. In addition, non-arterials can be secondary emergency response routes.
The City’s Residential Neighborhood Traffic Management Program, which identifies traffic management and traffic calming tools, specifies that emergency vehicle access should be accommodated consistent with response standards with implementation of appropriate traffic management measures. Additionally, if current emergency vehicle access does not meet existing response standards, traffic calming efforts should not further degrade response times.
The General Plan Public Safety Element states that City’s EOP does not indicate evacuation routes for emergency situations. The routes of escape from disaster-stricken areas will depend on the scale and scope of the disaster. However, emergency egress will most often take place on Chapman Avenue, Katella Avenue, Glassell Street, Lincoln Avenue, Orangewood Avenue, and Hewes Street.70
The City Drive is the nearest designated evacuation corridor to the project site.71 The proposed project would not affect access to The City Drive during project construction or operation. The proposed project does not include street closures and therefore would not affect emergency access to The City Drive evacuation corridor. Construction and internal circulation would comply with the applicable fire codes as required by the OCFD. Implementation of the proposed project during construction and operational would not impair or physically interfere with the City’s EOP, the General Plan Safety Element, or any other emergency response plan. Therefore, the proposed project would not affect emergency access. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?
According to the General Plan Public Safety Element, fire and its destructive potential are safety concerns within both the urban areas of the City and the undeveloped hillsides. Wildland fires are most problematic along the developed residential fringes of the hillsides, known as the wildlandurban interface. On a seasonal basis, dry vegetation, little seasonal rain, and Santa Ana wind conditions combine to increase wildfire potential. New development, particularly in the eastern 69 City of Orange. 2010.

portion of Orange, would result in increased fire hazards due to higher levels of interface between residential development and open grassland and vegetation along hillsides.72 The project site is in an urbanized area of the City and is surrounded by commercial and residential uses. The project site is currently developed with a commercial building and parking lot. The project site is not located near the wildland-urban interface or near the eastern portion of the City.
The project site is not located in or adjacent to a Fire Hazard Severity Zone as mapped by the California Department of Forestry and Fire Prevention (CAL FIRE).73 The nearest Fire Hazard Severity Zone is in the City of Villa Park, California, 5.31 miles northeast of the project site.
Additionally, as shown in the Environmental and Natural Hazard Policy Map of the General Plan Public Safety Element, the project site is not within a designated wildland fire hazard area.74 Therefore, the proposed project would not directly or indirectly expose people or structures to substantial hazards from wildland fires. There would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.

(d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
(e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? The information in this section is based, in part, on a Preliminary Water Quality Management Plan (WQMP) prepared for the project by Kimley-Horn on August 30, 2022, and the Due Diligence Geotechnical Exploration Report prepared for the project by Leighton and Associates, Inc. on July 18, 2019. These documents are available as Appendix E-1 and G-1 of this IS/MND, respectively.
Impact Analysis
(a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality?
A significant impact may occur if a project discharges water which does not meet the quality standards of agencies that regulate surface water quality and water discharges into stormwater drainage systems. Water quality within the City of Orange is regulated by the Santa Ana Regional Water Quality Control Board (Santa Ana RWQCB). Water quality impacts are often separated into two primary categories: construction-related impacts and operational impacts. The proposed project has the potential to release water pollutants during both construction and operations that may violate water quality standards.
Construction
The proposed project would involve ground-disturbing activities such as grading that have the potential to cause erosion. Grading activities, in particular, lead to temporarily exposed areas of loose soil, as well as sediment stockpiles, that are susceptible to uncontrolled sheet flow. Although 117
erosion occurs naturally in the environment, primarily from weathering by water and wind action, improperly managed construction activities can lead to substantially accelerated rates of erosion that are considered detrimental to the environment.
The National Pollutant Discharge Elimination System (NPDES) Program was established through the federal Clean Water Act to control and reduce pollutant discharges to surface water bodies.
Construction activities, including grading, that would result in the disturbance of 1 acre or more would require compliance with the General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activity (Construction General Permit). The proposed project site encompasses 5.86 acres and would therefore be required to comply with the Construction General Permit. The State Water Resources Control Board (State Water Board) adopted a requirement for obtaining NPDES Construction General Permit. To obtain coverage under the Construction General Permit, a project applicant must submit a Notice of Intent and a Stomrwater Pollution Prevention Plan (SWPPP). Activities subject to the Construction General Permit include clearing, grading, and ground disturbance. The purpose of the SWPPP is to identify the sources of sediment and other pollutants that could affect the quality of stormwater discharges and to describe and implement BMPs to reduce or eliminate sediment and other pollutants in stormwater and nonstormwater discharges resulting from construction activities.
The proposed project would prepare and implement a SWPPP. Additionally, the proposed project would be required to comply with MM GEO-1, which would require implementation of the recommendations pertaining to site grading from the Due Diligence Geotechnical Engineering Evaluation prepared for the proposed project on July 18, 2019, and revised January 4, 2021, by Leighton and Associates, Inc. (Appendix E-1), and would comply with the City’s grading ordinance. Compliance with the City’s grading ordinance, the SWPPP, and MM GEO-1 would ensure that the proposed project would not result in substantial soil erosion that would violate water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality during the construction phase.
The proposed project would comply with the City of Orange Stormwater Local Implementation Plan (LIP), which, in conjunction with the County of Orange Drainage Area Management Plan (DAMP) and its updates, is the principal policy and guidance document for the City’s NPDES Storm Water Program.75 The LIP requires all private and public works construction projects to implement and be protected by an effective combination of erosion and sediment controls and waste and materials management BMPs (best management practices) to prevent discharges into the storm drain system or watercourses. The required erosion and sediment controls and waste and materials management BMPs would be implemented during the proposed project’s construction phase, as well as the City’s designated construction-specific BMPs as set forth in DAMP Section
8.2.4.3 to reduce or eliminate discharges of pollutants from construction sites.76 75 City of Orange. July 2011. Stormwater Local Implementation Plan (LIP). Website:

Project design features aimed at reducing impacts to water quality, along with the implementation of MM GEO-1 and the project-specific construction BMPs shown in the SWPPP erosion and sediment control plans and grading plans would reduce potentially significant construction impacts to less than significant with mitigation incorporated.
Operations
The proposed project would comply with the requirements of the current NPDES MS4 Permit.
Responsibilities include, but are not limited to, designing BMPs into project features and operations to reduce potential impacts to surface water quality and to manage changes in the timing and quantity of runoff (i.e., hydromodification) associated with operation of the project. The final design would include measures and practices designed to mitigate potential water quality degradation and hydromodification of runoff from all portions of completed developments. The proposed project would include site design BMPs, source control BMPs, low impact development (LID) BMPs and hydromodification BMPs (as applicable). Since infiltration is infeasible, biolfiltration BMPs are proposed to treat the 85th percentile storm event prior to being conveyed into the public storm drains system. Examples of BMPs to be implemented at the project site may include, but are not limited to, the following:
• Subsurface infiltration galleries will be incorporated at or below the sub-surface slab grade, which is at the depth of the clay layer of the existing soil that has a very low infiltration rate.
• Minimize impervious areas and directly connected impervious areas by incorporating landscaped areas throughout the site surrounding the proposed building, within the common areas, and around the perimeter and interior walkways of the proposed building and parking structure.
• Educational materials will be provided to tenants, including brochures and restrictions to reduce pollutants from reaching the storm drain system. Employees and contractors would be trained to ensure awareness of activities that may result in pollutants reaching the storm drain, spill cleanup procedures, and proper waste disposal. • The owner will be responsible for performing trash pickup and sweeping of littered common areas on a weekly basis or more often when necessary. Responsibilities will also include noting improper disposal materials by tenants. • Source control BMPs such as storm drain signage, efficient irrigation systems and landscape design, and water conservation.
Additionally, the proposed project would implement site design BMPs, source control BMPs, and LID BMPs as specified in the WQMP. Site design BMPs would include, but are not limited to, landscape design that would minimize directly connected impervious areas, reduce runoff volume, and minimize the impervious area of the site. Nonstructural source control BMPs would include education for property owners, tenants, and occupants, restrictions on activities that could affect water quality, reducing pollutants through landscape management practices, maintenance of 119
BMPs, and common area litter control. Structural source control BMPs would include storm drain signage, efficient irrigation systems, landscape design, and water conservation measures.
Implementation of BMPs and compliance with the LIP and DAMP, as well as MM GEO-1, would ensure that the proposed project would not violate any water quality standards. Potentially significant impacts would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM GEO-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?
The Orange County Water District (OCWD) manages the Orange County Groundwater Basin (Basin), which covers approximately 350 square miles beneath the Tustin and Downey Plains. The City obtains approximately 55 percent of its water from City-owned groundwater wells.
As shown in the General Plan Natural Resources Element, groundwater recharge facilities within or adjacent to the City include the Santa Ana River and Santiago Creek. The project site is not located within or near the groundwater recharge facilities as mapped in the General Plan.77 The Due Diligence Geotechnical Engineering Evaluation (Appendix E-1) determined that a groundwater depth of 30 feet below ground surface (BGS) should be assumed for the purposes of project design. Additionally, no shallow groundwater was encountered during percolation test borings, although stratigraphy at the site may cause accumulation of perched groundwater at around 15 feet BGS. According to the report, fluctuations in groundwater level, and the occurrence of localized zones of temporary perched water and increases in soil moisture should be anticipated during/following winter seasons or periods of locally intense rainfall or stormwater runoff. 78 A Preliminary WQMP and Preliminary Hydrology Analysis were prepared for the proposed project by Kimley Horn and Fuscoe Engineering, dated August 30, 2022 and January 8, 2021, respectively, and are included in Appendix G-1 and Appendix G-2 of this IS/MND. Percolation tests conducted for the WQMP encountered a groundwater depth at 16 feet BGS.
Because both buildings have sub-surface parking, the BMP would need to be located at or below the sub-surface pad elevation. This would put it in the clay layer of the existing soil which, per the percolation test results, has a very low infiltration rate. Implementation of MM GEO-1 would ensure the project design includes consideration of the historic groundwater depth of 77 City of Orange. Orange General Plan Natural Resources Element, Figure NR-2, Drainage Areas and Water Recharge Facilities. Website:

approximately 30 BGS. With implementation of MM GEO-1, the proposed project would not substantially interfere with groundwater supplies or recharge. Potentially significant impacts would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM GEO-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
(i) result in substantial erosion or siltation on- or off-site? A significant impact may occur if a project results in a substantial alteration of drainage patterns that would result in a substantial increase in erosion or siltation during construction or operation of the project. As discussed in Impact 5.10(a), the proposed project must comply with NPDES requirements, which include obtaining coverage under the General Construction Permit by filing the Permit Registration Documents (a Notice of Intent and SWPPP, among others). The SWPPP identifies erosion control and sediment control BMPs that would meet or exceed measures required by the General Construction Permit to control potential construction-related pollutants.
According to the WQMP, under the existing conditions, the site sheet flows to the south and east before connecting to a 54-inch City storm drain line. The City storm drain flows southeasterly before draining to the Santa Ana River. All runoff into the Santa Ana River that is not infiltrated discharges the Pacific Ocean at Huntington Beach.79 The project site is served by an existing 24- inch drain that flows westerly, a 30-inch storm drain that flows westerly to a 54-inch storm drain along Garden Grove Boulevard, an 18-inch storm drain that flows southerly, and a 21-inch storm drain that flows southerly to the 54-inch storm drain along Garden Grove Boulevard. The flows from the 54-inch storm drain are conveyed easterly and discharged into Santa Ana River.
Under the proposed conditions, runoff would be conveyed via proposed curb, gutter, and storm drain systems. Each of the proposed lots and structures would be graded to drain toward the proposed private streets. Under final buildout conditions, low-flows and first-flush runoff from the stand-alone parking structure will be intercepted by curb and gutter prior to draining to a proposed Modular Wetland System BMPs. The mixed-use areas will have low-flows and first- flush runoff go to one of three proposed Modular Wetland System BMPs. The proposed parking structures and the mixed-use area are all within three distinct areas of the property and all within different parcels.
Flows would be treated by flow based Modular Wetland Systems prior to discharging into the public storm drain system. All BMPs would be privately maintained. Flows beyond the capture 79 Kimley-Horn. 2022. Preliminary Water Quality Management Plan (WQMP). August 30. 121
efficiency volume would bypass the system and discharge directly to the Santa Ana River via the proposed private and existing public storm drain system.81 The proposed curb, gutter, and storm drain systems would include BMPs to minimize erosion.
BMPs would include programs and policies, including structural controls, to control the discharge of pollutants from the project site.
With implementation of the BMPs, the proposed project would not alter drainage patterns such that substantial erosion or siltation would occur. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site
The proposed project would install an on-site storm drainage system and incorporate a vegetated swale on the east side of the proposed multi-use building that will collect flow and allow it to infiltrate into the shallow sand layer of soil below. According to the WQMP, the proposed project would decrease impervious surfaces as compared to existing conditions.82 Implementation of BMPs, such as landscape design that would minimize directly connected impervious areas, efficient irrigation systems, and minimization of impervious areas, would ensure that the proposed project does not contribute to surface runoff that would result in flooding. Therefore, the proposed project would not substantially increase surface runoff on the project site. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (iii) create of contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff or
According to the WQMP, the proposed project would decrease impervious surfaces as compared to existing conditions.83 Consistent with the requirements of the Construction General Permit, the proposed project would implement a SWPPP during construction that would include structural and nonstructural BMPs to prevent significant volumes of polluted runoff during construction. The proposed project would install an on-site storm drainage system and incorporate a vegetated swale on the east side of the proposed multi-use building that will collect flow and allow it to infiltrate 81 Kimley-Horn. 2022. Preliminary Water Quality Management Plan (WQMP). August 30. 82 Ibid. 83 Ibid. 122
into the shallow sand layer of soil below to reduce during operational activities. Collectively, these features would be included in the project design to help ensure that the proposed project would not contribute runoff that would exceed the capacity of downstream stormwater drainage systems or contribute substantial volumes of polluted runoff to the storm drainage system during construction and operations.
The total runoff flows from the proposed project would be slightly decreased from the existing conditions. Additionally, the flow to the existing 54-inch storm drain along Garden Grove Boulevard would not exceed the existing condition for the 2-year, 25-year, and 100-year storm events, as shown in Table 17 below.

Therefore, the proposed drainage would not exceed the capacity of stormwater drainage systems or provide substantial additional sources of polluted runoff. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (iv) impede or redirect flood flows?
The project site is located in an area designated as an Area with Reduced Flood Risk due to Levee (Zone X) and is therefore not susceptible to inundation from flood hazards. 84 As discussed above, the proposed project would include a curb, gutter, and storm drain system, as well as BMPs such as minimization of impervious areas and infiltration systems. The proposed project design criteria would meet the stormwater and flood protection goals as outlined in the Orange County Design Manual.85 Additionally, the proposed project would result in total runoff flows that are slightly decreased from the existing conditions.
86 Therefore, the proposed project would not impede or
redirect flood flows. Impacts would be less than significant. 84 Federal Emergency Management Agency. 2009. Flood Map No. 06059C0144J. Website: https://msc.fema.gov/portal/home. Accessed August 18, 2022. 85 Fuscoe Engineering, Inc. 2021. Preliminary Hydrology Analysis. January. 86 Ibid. 123
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
The project site is located in an area designated as an Area with Reduced Flood Risk due to Levee (Zone X).87 This zone is not within a special flood hazard area and is therefore not part of the 100- year flood hazard zone. According to the Federal Emergency Management Agency (FEMA) flood map, there is a levee system along the Santa Ana River corridor to the east of the project site. The nearest special flood hazard area is located inside of the levee system along the Santa Ana River corridor, 430 feet east of the project site. Therefore, the proposed project would not place housing within a 100-year flood hazard area. According to the Due Diligence Geotechnical Engineering Evaluation (Appendix E-1), based on the inland location of the site, impacts to the site due to seiches or tsunamis is not considered to be a hazard.88 Because the project site is not in a flood hazard area or at risk of seiches or tsunamis, no impacts would occur.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Because the project construction would disturb more than 1 acre of land, the proposed project would be required to comply with the terms of the Construction General Permit, which require the preparation and implementation of a SWPPP and associated BMPs to minimize the risk of pollutants from construction activities entering surface waters or groundwater basins.
During post-construction activities and operations of the proposed project, educational materials will be provided to tenants, including brochures and restrictions to reduce pollutants from reaching the storm drain system. Examples include tips for pet care, household tips, and proper household hazardous waste disposal. Tenants will be provided with these materials by the property management prior to occupancy, and periodically thereafter. Furthermore, the Owner would restrict ongoing activities that have the potential to create adverse impacts on water quality.
Activities include, but are not limited to: handling and disposal of contaminants, fertilizer and pesticide application restrictions, litter control and pick-up, and vehicle or equipment repair and maintenance, washing down of impervious surfaces, as well as any other activities that may potentially contribute to water pollution. The Owner will be responsible for the implementation and maintenance of each applicable nonstructural BMP, as well as scheduling inspections and 87 Federal Emergency Management Agency. 2009. Flood Map No. 06059C0144J. Website: https://msc.fema.gov/portal/home. Accessed August 18, 2022. 88 Leighton and Associates, Inc. 2019. Due Diligence Geotechnical Exploration Report. July 18. 124
maintenance of all applicable structural BMP facilities through its staff, landscape contractor, and/or any other necessary maintenance contractors.
Therefore, with implementation of BMPs during construction and operational activities, the proposed project would not conflict with or obstruct a water quality control plan or groundwater management plan. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. 125

(b) Cause a significant environment impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Impact Analysis
(a) Physically divide an established community?
A significant impact may occur if a project were sufficiently large enough or otherwise configured in such a way as to create a physical barrier within an established community. A typical example would be a project that involves a continuous right-of-way such as a roadway, which would divide a community and impede access between parts of the community. The proposed project is not of the scale or nature that could physically divide an established community, as the project site is currently developed and is surrounded by a mix of residential, commercial, and retail uses.
The proposed project would include the development of a 225-unit multi-family residential building with up to 9,000 square feet of ground level retail space, a 3,628 square foot private fitness center, and a 6,635 square foot lobby, leasing, and lounge area, as well as one stand-alone open parking structure, on a site that is currently developed with a commercial building, 4-story office building, and surface parking lots.
The project site is in an urbanized area of the City and is part of a larger multi-building office complex. The proposed project would be consistent with the existing character of the area. There are currently established residential communities surrounding the multi-building office complex to the north, south, and west. The proposed project would not physically divide or have any impact on these residential communities. Residents of these communities would not be impacted, as the proposed project would not encroach on these communities and would not remove or create a barrier to any roads or sidewalks used by the members of the surrounding residential communities.
The proposed project would not introduce infrastructure improvements that would bisect or transect the existing residential communities and would not interrupt access to the existing residential communities. The proposed project would increase pedestrian access and connectivity through the improvement of existing sidewalks.
Furthermore, the proposed project would integrate the proposed residential uses with existing transit corridors, commercial/retail, office, and open space uses in the surrounding area, which would result in a more integrated and connected urban environment. Therefore, the proposed project would not create any physical barriers or otherwise divide or disrupt the physical arrangement of the existing residential communities. No impacts would occur. 126
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
A significant impact may occur if a project is inconsistent with applicable land use plans or zoning designations and would cause adverse environmental effects, which these regulations are designed to avoid or mitigate. The adopted land use regulations applicable to the project site include the General Plan and Zoning Code. The following is an analysis of the proposed project’s consistency with the City’s land use regulations.
General Plan Consistency
The General Plan land use designation for the project site is UMIX and is within the West Chapman Avenue/Uptown Orange focus area. The UMIX designation provides for integrated commercial retail, professional office, housing, and civic uses within West Chapman Avenue/Uptown Orange and allows development densities of 1.5-3.0 FAR and 30-60 dwelling units per acre. These areas are intended to provide urban, high-intensity, regionally oriented activity centers that define the character of surrounding areas. Convenient transit access, innovative housing options, and pedestrian-oriented design are key considerations.
Project density is calculated utilizing the three parcels [231-261-13 (1.92 acres), 231-261-16 (0.95 acres), and 231-261-17 (2.99 acres)] totaling 5.86-acres. Thus, 225 dwelling units on 5.86 acres is approximately 38.4 dwelling units/acre. The proposed multi-family residential gross area is 249,664 square feet, ground level commercial is 9,000 square feet, amenity uses total 6,635 square feet, the fitness center is 3,628 square feet, and the existing office building at 790 The City Drive is 98,800 square feet resulting in a total of 367,727 square feet. Thus, the resulting FAR is 1.44.
Consistent with the UMIX designation of the project site, the proposed project would conform with and provide for the urban, high-intensity uses outlined in the General Plan for the project site, as well as the urban, high-intensity uses envisioned for the West Chapman Avenue/Uptown Orange focus area.
The proposed project includes the demolition of an existing single-story retail building and associated surface parking lot in order to construct a 6-story, 225-unit multi-family residential apartment complex with ground level retail/restaurant space, private fitness center, and lobby, leasing, and lounge area. The proposed project also includes construction of a 3-story basement level parking structure beneath the footprint of the mixed-use building, and construction of a standalone, two-story open parking structure for use by the adjacent multi-building office complex, to be located west of the mixed-use building and parallel to the south property line along Garden Grove Boulevard. The proposed project would be consistent with the goals and policies of the General Plan, including Policies 2.1 through 2.9 of the General Plan Land Use Element, which 127
encourage mixed-use development for purposes of promoting convenient and efficient relationships between housing, employment, services, and transit.89 Furthermore, the project site is within the West Chapman Avenue/Uptown Orange focus area, which consists of mostly commercial properties west of SR-57. This focus area contains a mix of major destination uses, including shopping, entertainment, offices, hotels, and a hospital. The West Chapman Avenue/Uptown Orange focus area can accommodate additional development intensity, including high-density multi-family residential development. The proposed project includes the development of 225 additional residential dwelling units; therefore, the proposed project would be consistent with the development envisioned for this area.
Zoning Consistency
The Zoning Code (Title 17 of the Municipal Code) establishes the basic zoning regulations under which land is developed and utilized and by which the City’s General Plan is systematically implemented. It is the method the City uses to implement control of land uses, in accordance with the General Plan goals and policies.
Per the zoning map, the zoning district of the project site is UMU. Zoning and development standards for the UMU zone are incorporated into Chapter 17.19 (Mixed-Use Districts) of the Zoning Code. The UMU zoning district is intended to provide urban, high-intensity, regionally oriented activity centers. This zoning district provides for integrated commercial retail, professional office, residential, and civic uses. Residential development is allowed, either as part of a mixed-use project or as a freestanding use. Convenient transit access, innovative housing options, and pedestrian-oriented design are key considerations.
Similar to the General Plan land use designation, the UMU zoning district permits a residential density range of 30 to 60 du/acre and a nonresidential intensity range of 1.5 to 3.0 FAR. The proposed multi-family residential gross area is 249,664 square feet, ground level commercial is 9,000 square feet, amenity uses total 6,635 square feet, the fitness center is 3,628 square feet, and the existing office building at 790 The City Drive is 98,800 square feet resulting in a total of 367,727 square feet. Thus, the resulting FAR is 1.44. The proposed project is consistent with the UMU zoning district’s permitted intensity range.
Furthermore, consistent with Chapter 17.19 (Mixed-Use Districts) of the Zoning Code, the proposed project provides direct pedestrian linkages to adjacent public sidewalks, as well as enhanced pedestrian amenities throughout the project development, including seating, pedestrian area lighting, common open space, and similar items to create a pleasant pedestrian experience.
The proposed project would also locate uses in proximity to one another without intervening parking lots, so it is convenient for patrons to walk between the various uses and only park their vehicles once. The proposed project would create a pedestrian scale and character of development along the street by providing varying roof heights and incorporating pedestrian scale elements near public sidewalks to contribute to active street environment. Lighting would also be provided along 89 City of Orange. 2010. General Plan Land Use Element, Website:

sidewalks, courtyards, and other common areas to enhance the pedestrian environment and increase public safety.
Conclusion
Based on the preceding information, implementation of the proposed project would be consistent with the General Plan and Zoning Code. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.

Impact Analysis
(a) 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?
A significant impact would occur if a project was located in an area used or available for extraction of a locally or regionally important mineral resource, if the project converted an existing or potential future locally or regionally important mineral extraction use to another use, or if the project affected access to a site in use or potentially available for locally or regionally important mineral resource extraction. According to the General Plan Natural Resource Element93 and the Land Use Policy Map,94 mineral resource deposits are primarily limited to sand and gravel resources in and along the Santa Ana River and Santiago Creek. These mineral resources have mostly been exhausted from previous mining activity and urbanization. The Santa Ana River is located 430 feet east of the project site; however, the project site and the segment of the Santa Ana River near the project site are not designated for mineral resources or mining activities.
Additionally, mineral mining uses are not permitted on the site under the UMU zone. Therefore, the proposed project would not result in the loss of mineral resources that are of value to the region and to residents of the State. Therefore, no impacts would occur.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (b) 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? The project site is in an urbanized area of the City, and the site is not permitted for mining use under the UMU zone. Because the project site lacks locally important mineral resource recovery sites and is not permitted for mining use, the proposed project would not result in the loss of availability of a locally important mineral resource recovery site. Therefore, no impacts would occur.

(a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?

(c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
Impact Analysis
(a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Short-Term Construction Impacts
A significant impact would occur if construction activities result in the generation of a substantial temporary increase in ambient noise levels in excess of standards established in Chapter 8.24, the noise ordinance of the Municipal Code. According to Section 8.24.050 of the Municipal Code, noise sources associated with construction, repair, remodeling, or grading of any real property are exempt from the City’s exterior noise performance standards, provided said activities take place between the hours of 7:00 a.m. and 8:00 p.m. on any day except for Sunday or a Federal holiday, or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday or a Federal holiday. Noise generated outside of the hours specified are subject to the noise standards identified in the City’s noise performance standards for fixed noise sources, summarized in Table 8.24.040 of the Municipal Code.
Two types of short-term noise impacts would occur during site preparation and project construction. The first type would result from the increase in traffic flow on local streets, associated with the transport of workers, equipment, and materials to and from the project site. The transport of workers and construction equipment and materials to the project site would incrementally increase noise levels on access roads leading to the site. Because workers and construction equipment would use existing routes, noise from passing trucks would be similar to existing vehicle-generated noise on these local roadways. An increase of 3 dBA in traffic noise levels could insult in potentially significant impact. Typically, a doubling of the Average Daily Traffic (ADT) hourly volumes on a roadway segment is required in order to result in an increase of 3 dBA in traffic noise levels; which is the lowest change that can be perceptible to the human ear in outdoor environments. Project-related construction trips would not double the hourly or daily traffic volumes along any roadway segment in the project vicinity. For these reasons, short-term 132
intermittent noise from trucks would be minor when averaged over a longer time-period.
Therefore, short-term construction-related noise impacts associated with worker commute and equipment transport to the project site would not result in a substantial increase in ambient noise levels in excess of applicable significance thresholds and would be less than significant.
The second type of short-term noise impact is related to noise generated during construction on the project site. Construction noise levels are rarely steady in nature and, often, fluctuate depending on the type and number of equipment being used at any given time. In addition, there could be times where large equipment is not operating and noise would be at or near normal ambient levels.
Construction is completed in discrete steps, each of which has its own mix of equipment and its own noise characteristics. These various sequential phases would change the character of the noise generated on the site and, therefore, the noise levels surrounding the site as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction-related noise ranges to be categorized by work phase.
The site preparation phase, which includes excavation and grading activities, tends to generate the highest noise levels because the noisiest construction equipment is earthmoving equipment.
Earthmoving equipment includes excavating machinery and compacting equipment, such as bulldozers, draglines, backhoes, front loaders, roller compactors, scrapers, and graders. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 or 4 minutes at lower power settings.
Construction of the proposed project is expected to require the use of frontend loaders, excavators, haul trucks, water trucks, concrete mixer trucks, and pickup trucks. The maximum noise level generated by each concrete mixing truck is assumed to be 85 dBA maximum noise level (Lmax) at 50 feet from this equipment.95 Each frontend loader would also generate 85 dBA Lmax at 50 feet.
The maximum noise level generated by excavators is approximately 85 dBA Lmax at 50 feet. Each doubling of sound sources with equal strength increases the noise level by 3 dBA.
A reasonable assumption is that the construction equipment, as described above, would operate simultaneously and continuously over at least a 1-hour period in the vicinity of the closest existing residential receptors, but would move linearly over the project site as the contractor performs earthmoving operations, spending a relatively short amount of time adjacent to any one receptor.
Assuming that each piece of construction equipment operates at some distance from the other equipment, a reasonable worst-case combined noise level during this phase of construction would be 90 dBA Lmax at a distance of 50 feet from the acoustic center of a construction area. The acoustical center reference is used because construction equipment must operate at some distance from one another on a project site, and the combined noise level as measured at a point equidistant from the sources (acoustic center) would be the worst-case maximum noise level. These operations would be expected to result in a reasonable worst-case hourly average of 86 dBA equivalent sound 95 Federal Highway Administration (FHWA). 2006. Highway Construction Noise Handbook. August. 133
level (Leq) at a distance of 50 feet from the acoustic center of a construction area. The effect on sensitive receptors is evaluated below.
The closest noise-sensitive receptors to the proposed construction footprint are the single-family residences located south of the southern boundary of the project site, approximately 145 feet from the acoustic center of construction activity where multiple pieces of heavy construction equipment would potentially operate at the project site. There is an existing 6-foot high sound wall along the northern property line of these residences bordering Garden Grove Boulevard. At this distance and assuming minimum shielding reduction for the existing sound wall, worst-case construction noise levels could range up to approximately 76 dBA Lmax, intermittently, and could have an hourly average of up to 72 dBA Leq, at the façades of the nearest single-family residential homes.
These construction activities would be required to comply with the City’s exterior noise performance thresholds unless restricted to daytime hours of 7:00 a.m. and 8:00 p.m. on any day except for Sunday or a Federal holiday, or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday or a Federal holiday. Therefore, compliance with the City’s permissible hours of construction, as well as implementing the best management noise reduction techniques and practices outlined in MM NOI-1, would ensure that construction noise would not result in a substantial temporary increase in ambient noise levels in excess of applicable standards. Therefore, with implementation of MM NOI-1, potentially significant temporary construction noise impacts would be reduced to less than significant.
Operational/Stationary Source Noise Impacts
A significant impact would occur if operational noise levels generated by stationary noise sources at the project site would exceed the following levels at the outdoor activity area of any residential land use in the project vicinity:
• 55 dBA Leq or 70 dBA Lmax between the hours of 7:00 a.m. and 10:00 p.m.; or • 50 dBA Leq or 65 dBA Lmax between the hours of 10:00 p.m. and 7:00 a.m.
According to the City’s noise ordinance, for multi-family residential or mixed-use developments located within the General Plan’s urban mixed-use, neighborhood mixed-use, old town mixed-use or medium density residential land use districts, the City’s exterior noise standards apply to common recreation areas only.
The proposed project would generate noise from parking lot activities, which includes people conversing, doors shutting, engine startup, and slow-moving vehicles, at the proposed parking garage; and from new exterior mechanical equipment sources, such as mechanical ventilation systems on the proposed multi-family residential uses.
Parking Lot Activities at Proposed Stand-Alone Parking Structure The nearest noise-sensitive receptors to the southern project boundary are the single-family residences located across Garden Grove Boulevard. The outdoor use areas of these residences 134
would be located approximately 150 feet from the nearest acoustic center of parking lot activity within the proposed south parking structure.
Assuming a minimum of one parking movement per stall per hour in the ground level of the proposed south parking structure and taking into account shielding from the existing sound wall that traverses the backyards of these nearest residences, the resulting hourly average project operational noise levels would be approximately 44 dBA Leq at the nearest residential receptor, with a maximum noise level of 50 dBA Lmax. Detailed assumptions and calculations are provided in Appendix H.
These noise levels would not exceed the City’s daytime exterior noise limits of 55 dBA Leq and 70 dBA Lmax for residential receptors. Because parking lot activity would be reduced at this parking structure at nighttime, reasonable worst-case combined hourly average noise levels at nighttime, including shielding from the existing sound wall, would range up to 38 dBA Leq, with a maximum noise level of 50 dBA Lmax. This assumes approximately 25 percent of the parking stalls experiencing a parking movement per hour. These operational noise levels would also not exceed the City’s nighttime exterior noise limit of 45 dBA Leq and 65 dBA Lmax for residential receptors.
Therefore, the impact of noise generated by parking lot activities at the proposed parking structure to off-site sensitive receptors would be less than significant.
Rooftop Mechanical Equipment Operations
At the time of preparation of this analysis, details were not available pertaining to proposed rooftop mechanical ventilation systems for the proposed project; therefore, a reference noise level for typical rooftop mechanical ventilation systems was used. Noise levels from typical residential rooftop mechanical ventilation equipment are anticipated to range up to approximately 60 dBA Leq at a distance of 25 feet. Proposed rooftop mechanical ventilation systems could be located as close as 130 feet from the nearest off-site noise-sensitive receptor, which is the single-family residence located south of the project site. At this distance, and taking into account shielding from the rooftop parapet, noise generated by rooftop mechanical ventilation equipment on the project site would be reduced to below 41 dBA Leq at the nearest noise-sensitive receptor. These noise levels would not exceed the City’s most restrictive performance standard, the nighttime exterior noise limit of 45 dBA Leq for residential receptors. Therefore, the impact of noise produced by proposed mechanical ventilation equipment operations to off-site sensitive receptors would be less than significant.
Operational/Mobile Source Noise Impacts
According to the General Plan, the City considers permanent increases in ambient noise levels to be significant if a new development would result in an increase by any of the following levels as measured at the outdoor activity area of any noise-sensitive land use:
• +5 dBA CNEL where the existing ambient noise level is less than 65 dBA. • +3 dBA CNEL where the existing ambient noise level is greater than 65 dBA. 135
The FHWA highway traffic noise prediction model (FHWA RD-77-108) was used to evaluate existing and cumulative (Year 2024) traffic noise conditions in the vicinity of the project site. The daily traffic volumes were obtained from the traffic analysis prepared for the project by LLG. 96 The resultant noise levels were weighed and summed over a 24-hour period in order to determine the CNEL values. The traffic noise modeling input and output files are included in Appendix H of this IS/MND. Table 19 shows a summary of the traffic noise levels for Existing, Existing Plus Project, Year 2024 Cumulative, and Year 2024 Cumulative Plus Project conditions as measured at 50 feet from the centerline of the outermost travel lane.

The highest traffic noise level increase with implementation of the proposed project would occur along Garden Grove Boulevard west of The City Drive South under Existing Plus Project conditions. Along this roadway segment, the proposed project would result in an increase of 0.1 dBA, which is well below a 3 dBA increase that would be considered a substantial permanent increase in traffic noise levels compared with traffic noise levels that would exist without the project. Therefore, project-related traffic noise impacts on existing traffic noise levels in the project vicinity would be less than significant.
Noise Land Use Compatibility
The City of Orange establishes land use compatibility standards in the General Plan.97 These standards reflect the levels of noise exposure from transportation related sources that are considered to be normally acceptable for various types of land uses.
The proposed project is designated as a new multi-family, mixed-use development located within an Urban Mixed-Use zoning district. Under this designation, exterior noise environments (specifically common outdoor recreational areas) up to 65 A-weighted decibel (dBA) Community 96 Linscott, Law and Greenspan Engineers (LLG). 2020. 840 The City Drive South Apartments Project.

Noise Equivalent Level (CNEL), and interior noise environment up to 45 dBA CNEL, are considered to be normally acceptable for this type of land use.
The dominant noise sources in the project vicinity were from vehicular traffic on Garden Grove Boulevard and The City Drive South. To document noise levels from these sources, traffic noise modeling was performed. The Federal Highway Administration (FHWA) highway traffic noise prediction model (FHWA RD-77-108) was used to evaluate existing and cumulative (year 2024) traffic noise conditions in the vicinity of the project site. The projected traffic noise levels along roadways adjacent to the project site were analyzed to determine compliance with the City’s land use compatibility standards. The daily traffic volumes were obtained from the traffic analysis prepared for the project by LLG.98 The resultant noise levels were weighed and summed over a 24-hour period in order to determine the CNEL values. The traffic noise modeling input and output files are included in Appendix H of this IS/MND.

Traffic noise levels along Garden Grove Boulevard, adjacent to the project site and west of The City Drive South would range up to 68.2 dBA CNEL as measured at 50 feet from the centerline of the outermost travel lane. The proposed common outdoor recreational areas, the pool area located in the southern half of the project site east and south of the proposed residential buildings, is setback approximately 115 feet from the centerline of the nearest travel lane and would be shielded from Garden Grove Boulevard by the intervening proposed buildings. Therefore, distance attenuation and shielding would reduce maximum traffic noise levels from traffic on Garden Grove Boulevard to below 58 dBA CNEL as measured at the nearest proposed outdoor active use areas. 98 Linscott, Law and Greenspan Engineers (LLG). 2020. 840 The City Drive South Apartments Project. October. 137
This ambient noise level is within the City’s maximum allowable exterior noise exposure limit of 65 dBA CNEL for multi-family, mixed-use residential land uses.
The façade of the nearest proposed residential building at the project site would be setback approximately 80 feet from the centerline of the outermost travel lane of Garden Grove Boulevard.
At this distance, traffic noise levels would range up to approximately 65.6 dBA CNEL at the nearest façade of the proposed residential building. Based on the EPA’s Protective Noise Levels, with a combination of walls, doors, and windows, standard construction in accordance with building code requirements for multi-family residential developments would provide 25 dBA in exterior-to-interior noise reduction with windows closed and 15 dBA or more with windows open.99
With windows open, the interior noise levels of the proposed units nearest to and facing Garden Grove Boulevard would not meet the City’s interior noise standard of 45 dBA CNEL (i.e., 65.6 dBA-15 dBA = 50.6 dBA). However, the proposed residential buildings would include mechanical ventilation, which would allow windows to remain closed for prolonged periods of time, sufficiently reducing traffic noise levels to meet the interior noise level standard of 45 dBA CNEL (i.e., 65.6 dBA–25 dBA = 40.6 dBA). Air conditioning units would give an occupant the option of controlling noise by keeping the windows shut. Therefore, based on the project design of included mechanical ventilation systems, noise levels from traffic on Garden Grove Boulevard would also not result in an exceedance of the City’s interior noise level standard for 45 dBA CNEL as measured inside the nearest façade of the proposed residential units.
Traffic noise levels along The City Drive South, adjacent to the project site and north of Garden Grove Boulevard would range up to 66.0 dBA CNEL as measured at 50 feet from the centerline of the outermost travel lane. The proposed common outdoor recreational area, the pool area located in the southern half of the project site east and south of the proposed residential buildings, would be approximately 50 feet from the centerline of the outermost travel lane of The City Drive South.
This patio and pool deck area would be elevated approximately 8 feet above the roadway elevation, and would be shielded by the proposed raised planter beds and glass patio fence, which would be expected to provide a minimum noise reduction of 5 dBA as measured at this outdoor area compared to unshielded conditions. Therefore, traffic noise levels would range up to approximately 61 dBA CNEL in the nearest proposed common outdoor recreational area. This ambient noise level is within the City’s maximum allowable exterior noise exposure limit of 65 dBA CNEL for multi-family, mixed-use residential land uses.
The façade of the nearest proposed residential building at the project site would be setback approximately 40 feet from the centerline of the outermost travel lane of The City Drive South. At this distance, traffic noise levels would range up to approximately 67 dBA CNEL at the nearest façade of the proposed residential building.
With windows open, the interior noise levels of the proposed units nearest to and facing The City Drive South would not meet the City’s interior noise standard of 45 dBA CNEL (i.e., 67 dBA-15 99 United States Environmental Protection Agency (EPA). 1978. Protective Noise Levels. November. Website:

dBA = 52 dBA). However, the proposed residential buildings would include mechanical ventilation, which would allow windows to remain closed for prolonged periods of time, sufficiently reducing traffic noise levels to meet the interior noise level standard of 45 dBA CNEL (i.e., 67 dBA – 25 dBA = 42 dBA). Air conditioning units would give an occupant the option of controlling noise by keeping the windows shut. Therefore, based on the project design of included mechanical ventilation systems, noise levels from traffic on The City Drive South would also not result in an exceedance of the City’s interior noise level standard for 45 dBA CNEL as measured inside the nearest façade of the proposed residential units, and traffic noise impacts to the proposed project to be less than significant.
Significance Determination: Potentially significant impact for short-term temporary construction. Less than significant impact for Parking Lot Activities at Proposed Stand-Alone Parking Structure, Rooftop Mechanical Equipment Operations, and Operational/Mobile Source Noise.
Mitigation Measures:
MM NOI-1 To reduce potential construction noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project:
• The construction contractor shall ensure that all equipment driven by internal combustion engines shall be equipped with mufflers, which are in good condition and appropriate for the equipment.
• The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. • The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where such market available technology exists. • At all times during project grading and construction, the construction contractor shall ensure that stationary noise-generating equipment shall be located as far as practicable from sensitive receptors and placed so that emitted noise is directed away from the nearest residential land uses.
• The construction contractor shall designate a noise disturbance coordinator who would be responsible for responding to any local complaints about construction noise. The disturbance coordinator would determine the cause of the noise complaints (starting too early, bad muffler, etc.) and establishment reasonable measures necessary to correct the problem. The construction contractor shall visibly post a telephone number for the disturbance coordinator at the construction site.
• The construction contractor shall ensure that all on-site demolition and construction activities, including deliveries and engine warm-up, shall be restricted to the hours between 7:00 a.m. and 8:00 p.m. on any day except for Sunday or a Federal holiday, or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday or a Federal holiday.
139
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated for short-term temporary construction. Less than significant impact for Parking Lot Activities at Proposed Stand-Alone Parking Structure, Rooftop Mechanical Equipment Operations, and Operational/Mobile Source Noise.
(b) Generation of excessive groundborne vibration or groundborne noise levels? A significant impact would occur if the proposed project would generate groundborne vibration or groundborne noise levels in excess of established standards. The City of Orange has not established its own vibration impact criteria. Therefore, for purposes of this analysis, the Federal Transit Administration’s (FTA) vibration impact criteria are utilized. The FTA has established industry accepted standards for vibration impact criteria and impact assessment. These guidelines are published in its Transit Noise and Vibration Impact Assessment Manual.100 Groundborne noise is an effect of groundborne vibration and only exists indoors, since it is produced from noise radiated from the motion of the walls and floors of a room, and may also consist of the rattling of windows or dishes on shelves. In general, if groundborne vibration levels are do not exceed levels considered to be perceptible, then groundborne noise levels would not be perceptible in most interior environments. Therefore, this analysis focuses on determining exceedances of groundborne vibration levels.
Although groundborne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects such as the shaking of a building can be notable. When assessing annoyance from groundborne vibration, vibration is typically expressed as root mean square (rms) velocity in units of decibels of 1 microinch per second. To distinguish these vibration levels referenced in decibels from noise levels referenced in decibels, the unit is written as “VdB.” In extreme cases, excessive groundborne vibration has the potential to cause structural damage to buildings. Common sources of groundborne vibration include construction activities such as blasting, pile driving and operating heavy earthmoving equipment. However, construction vibration impacts on building structures are generally assessed in terms of peak particle velocity (PPV). For purposes of this analysis, project-related impacts are expressed in terms of PPV.
Short-Term Construction Vibration Impacts
Of the variety of equipment that would be used during construction, small vibratory rollers would produce the greatest groundborne vibration levels. Impact equipment such as pile drivers is not expected to be used during construction of the proposed project. Small vibratory rollers produce groundborne vibration levels ranging up to 0.101 inch per second (in/sec) PPV at 25 feet from the operating equipment.
The heaviest construction equipment would potentially operate as close as 50 feet from the nearest off-site structure, the office building located west of the project construction footprint. At this 100 Federal Transit Administration (FTA). 2018. Transit Noise and Vibration Impact Assessment Manual. September. 140
distance, groundborne vibration levels would range up to 0.04 in/sec PPV from operation of the types of equipment that would produce the highest vibration levels. This is well below the FTA’s Construction Vibration Impact Criteria of 0.2 in/sec PPV for buildings of non-engineered timber and masonry. Therefore, the impact of groundborne vibration levels on off-site receptors would be less than significant.
Operational Vibration Impacts
The proposed project does not include any permanent noise sources that would expose persons in the project vicinity to groundborne vibration levels that could be perceptible without instruments at any existing sensitive land use in the project vicinity. Therefore, operational vibration impacts on proposed on-site receptors would be less than significant.
Significance Determination: Less than significant impact for short-term construction vibration and operation vibration.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact for short-term construction vibration and operation vibration.
(c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
The nearest public use airports to the project site are John Wayne Airport and Fullerton Municipal Airport, approximately 6.4 miles south and 8.1 miles northwest of the project site, respectively.
Because of its distance from the airport runways, and the orientation of the runways relative to the project site, the project site is located outside of the airport’s 55 dBA CNEL noise contours. While airport noise would be audible when planes fly over, it would be less than significant. No private airstrips are located within the vicinity of the project site. Therefore, implementation of the proposed project would not expose persons residing or working in the project site to excessive noise levels associated with private airstrip or public airport noise. No impact would occur.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. 141

The information in this section is based, in part, on a Workforce Housing Analysis prepared by the Natelson Dale Group, Inc., for the proposed project on October 1, 2020, and included as Appendix I of this IS/MND. The purpose of the Workforce Housing Analysis is to help demonstrate the relationship of the proposed project to the workforce of the City of Orange.
Impact Analysis
(a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
The proposed project would include the development of 225 apartment units, up to 9,000 square feet of retail space; a 3,628-square-foot fitness center; a 6,635-square-foot lobby, leasing, and lounge area; and a swimming pool courtyard on a 5.86-acre site. The proposed project would require a temporary construction workforce and a permanent operational workforce, and would provide residential housing on-site, all of which could induce population growth in the project area.
A Workforce Housing Analysis was prepared for the proposed project on October 1, 2020, (Appendix I) and included an analysis of housing affordability and rental rates in Orange County, median income in Orange County, and potentially appropriate tenants based on occupational categories. The Workforce Housing Analysis concluded that there is an available pool of workers in the City of Orange that would be potentially appropriate tenants for the proposed project.101 The number of construction workers needed during construction would largely depend on the specific stage of construction. The proposed project would not include the construction of roads or new infrastructure that would result in indirect population growth. However, once operational, the proposed project would require employees to manage and operate the apartment complex, retail space, and amenities. The most recent data from September 2020 provided by the California Employment Development Department (EDD) found that the unemployment rate for the City of 101 Natelson Dale Group, Inc.

Orange is 8.4 percent, or 5,900 people.102 As such, the proposed project’s temporary and permanent employment requirements could be met by the City of Orange’s existing labor force without new residents needing to relocate into the project region. Because of the nature of the proposed project, workers who are already present in the local labor force typically fill the kinds of labor skills required for the proposed project.
The proposed apartment building would include 225 apartment units in an area designated UMIX and zoned UMU. The proposed project would create housing for an estimated 697 residents based on the City of Orange average household size of 3.08 persons. 103 An additional 697 residents would
represent less than 1 percent of the City’s population of 138,669. 104
According to the General Plan Housing Element, the City of Orange has a jobs/housing balance ratio of 2.11. The recommended target standards for jobs-housing ratio is approximately 1.5. 105,106
The City of Orange’s jobs/housing balance indicates that there are more jobs available than housing to accommodate workers within the City, creating demand for new housing to accommodate those employed in the City of Orange. Additionally, the General Plan Housing Element has identified that Orange’s fair share of the regional housing growth need according to SCAG is 363 housing units.107 As such, the proposed project would support the housing needs of the City of Orange and the region.
108
Because the proposed project would help the City of Orange meet its housing needs, and because the proposed project is consistent with the planned for population growth of both the General Plan and the most current Housing Element , impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
The proposed project would include the development of up to 225 apartment units; up to 9,000 square feet of retail space; a 3,628-square-foot fitness center; a 6,635-square-foot lobby, leasing, 102 California Employment Development Department. 2020.

Generally, the jobs-housing ratio is a ratio between a measure of employment and a measure of housing in a given area of analysis. The most basic measure is the ratio of the number of jobs to the number of housing units in an area. To calculate this measure, divide the number of jobs by the number of housing units. For example, if 15,000 persons are employed in a city and 20,000 housing units exist, the city’s jobs-housing unit ratio is 15,000/20,000 = 0.75.

and lounge area; and a swimming pool courtyard on a 5.86-acre site. The project site is currently developed with a commercial building, 4-story office building, and parking lot. The site does not support residential housing in its existing condition as the site is currently developed with commercial retail and office uses; therefore, the proposed project would not displace existing housing. The proposed new residential units would support the City’s housing needs by providing new housing for an estimated 697 people. Therefore, the proposed project would not displace a substantial number of existing housing necessitating the construction of replacement housing elsewhere. No impacts would occur.

A letter sent by FCS to the Orange Police Department on October 16, 2020 did not receive a response.
Impact Analysis:
(a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:
(i) Fire protection?
A significant impact may occur if the fire department could not provide adequate services to a project, or if a new or physically altered fire station would be necessary to serve the project. The project site is served by the OCFD, which provides fire protection and emergency medical services to the City of Orange. FCS received information pertaining to the proposed project from OCFD on November 7, 2020 (Appendix J-2).
The services provided by the OCFD include fire prevention and suppression, paramedic, emergency medical, emergency preparedness, and hazardous materials management/environmental safety. The OCFD consists of three divisions: Fire Administration, Fire Prevention, and Training and Safety. The Operations Division staffs one fire truck (ladder truck), one quintuple combination pumper (quint), seven fire engines (pumpers) staffed with one paramedic and two Emergency Medical Technicians (EMTs) at eight fire stations, and four rescue ambulances staffed with two paramedics at four fire stations. The OCFD has an average response 145
time of 3.23 minutes across all responding units. The average response time for Station 6 units into the fire district near the proposed project is 3.34 minutes.109 The project site would be served by Fire Station 6, located at 345 City Drive South, 0.8 mile north of the project site. However, because the project site is located near the western border of the City, the primary emergency response may come from outside the City of Orange in the event that Fire Station 6 resources are committed to another emergency.110 Emergency access to the site is included in the proposed site plan. Emergency vehicle access to the site would be provided via The City Drive South. The proposed project design would not interfere with emergency vehicle access to the site or to other areas surrounding the site. Additionally, the proposed project would implement alarm and notification systems and security in compliance with OCFD requirements to minimize the occurrence of fires and reduce the reporting time in the event of a fire.
Access to the project site is currently provided and would continue to be provided via one fullaccess driveway located along The City Drive and one right-turn-in-, right-turn-out-only driveway located along Garden Grove Boulevard, which are both shared with the adjacent office complex.
According to the Fire Master Plan prepared for the proposed project (Appendix J-1), fire lanes ranging from 20 feet wide to 29.8 feet wide would be provided throughout the project site, including the driveways to the north and west of the proposed mixed-use building and driveways surrounding the parking structure. Fire lanes would be clearly identified by red fire lane curbs and fire lane signs. The truck turning radius on the driveways along The City Drive and Garden Grove Boulevard would be 50 feet wide to accommodate fire trucks. All proposed structures would be installed with automatic fire sprinklers that comply with the Chapter 9 of the 2019 California Fire Code.
111 Fire hydrants currently exist throughout the project site and would accommodate the proposed project. Additionally, emergency access walkways, ladder access, emergency escapes, rescue doors, and windows would be provided in accordance with the Fire Master Plan. The Fire Master Plan would be approved by OCFD.
The proposed project is within OCFD’s current projections and is therefore not expected to impede OCFD’s fire response times.112 The proposed project is not expected to result in the need for new fire department facilities or the expansion of existing facilities in order to serve the proposed project and the surrounding community. Furthermore, as discussed in more detail in Section 5.17, Transportation, according to the TIA prepared for the proposed project by LLG on December 11, 2020, the proposed project would not have substantial impacts on nearby intersections or roadways and therefore would not impede emergency access to the project site. Furthermore, as previously discussed in Section 5.9, Hazards and Hazardous Materials, the proposed project does not include street closures and therefore would not affect emergency access to The City Drive evacuation corridor. Construction and internal circulation would comply with the applicable fire codes as 109 Southerland, Kevin. Deputy Fire Chief/Fire Marshal, Orange Fire Department. Personal communication: email. November 7, 2020. 110 Ibid. 111 2019 California Fire Code, Section 914.3.1 Automatic Sprinkler System.

required by the OCFD. The site plans would be reviewed and approved by the Orange Building and Fire Departments to ensure adequate emergency access.
The proposed project would be subject to compliance with the fire provisions specified in the latest CBC and all incorporated amendments, and the 2019 California Fire Code with amendments. The site plans and Fire Master Plan would be reviewed and approved by the Orange Building and Fire Departments to ensure adequate emergency access, fire hydrant availability, and compliance with all applicable codes and standards. Additionally, Municipal Code Section 15.38 provides for a Fire Protection Facilities Fee Program. The program requires new residential developments to pay a fire protection facilities fee to aid in offsetting the increased demand for fire services created by residential projects. The fee for the proposed project would be $1,328 per dwelling unit. The fee is due on the date of final inspection or certificate of occupancy for each unit, whichever occurs first.113 Payment of the fire protection facilities fee would help to reduce impacts resulting in a need for new or expanded fire protection facilities.
The incorporation of the proposed project’s design features for fire safety, the payment of the fire protection facilities fee, and compliance with the CBC and International Fire Code would ensure that there is no need for new or expanded fire protection facilities. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (ii) Police Protection?
A significant impact may occur if a project creates the need for new or physically altered police facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives.
Police protection services are provided by the Orange Police Department services to the City, including the project site. According to the General Plan Public Safety Element, to maintain the City’s ability to serve current residents and businesses, applicants would be required to provide for adequate services and equipment to serve residents and businesses of new developments, and land uses will be evaluated and modified, if necessary, to facilitate access to emergency services, meet service standards, and ensure land use compatibility. 114 Because the proposed project is consistent with planned for growth in the General Plan and would comply with the General Plan Safety 113 Southerland, Kevin. Deputy Fire Chief/Fire Marshal, Orange Fire Department. Personal communication: email. November 7, 2020. 114 City of Orange. 2010. General Plan Public Safety Element. Website:

Element, it would be expected that emergency response would occur with acceptable response times.
The project applicant would pay its fair share of the Police Facility Development Fees to help finance police facilities required by new development in order to avoid adversely impacting existing police protection facilities, as required by Municipal Code Section 3.13.115 The Police Facility Development Fees ensure that development bears a proportionate share of the cost of public facilities and services necessary to accommodate such development.116 Additionally, the project plans would be reviewed and approved by the Orange Building and Police Departments, which would ensure that adequate safety and crime prevention measures are provided within the project’s design. For these reasons, the proposed project would not result in a need for new or expanded police protection facilities. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (iii) Schools?
The proposed project is in the OUSD area. The schools that would be affected by the proposed project include Lampson Elementary School, located at 13321 Lampson Avenue in Garden Grove,
0.75 mile northwest of the project site, and Fairhaven Elementary School, located at 1415 Fairhaven Avenue in Santa Ana, 2.35 miles east of the project site (Appendix J-2). 117 Additionally,
the proposed project is located near Portola Middle School, located at 270 North Palm Drive in Orange, 1.5 miles northeast of the project site; and Orange High School, located at 525 North Shaffer Street in Orange, 2.87 miles northeast of the project site.
The current OUSD enrollment is 26,719, with a current capacity of 33,760. Lampson Elementary School’s current enrollment is 707 with a capacity of 842. Fairhaven Elementary School’s current capacity is 465 with a capacity of 682.118 Portola Middle School’s enrollment is 664 students,119 and Orange High School’s enrollment is 1,727 students.120 Based on the current standard student generation factors used by OUSD,121 the proposed project would be expected to generate a total of 38 students, including 27 elementary school students, three middle school students, and eight 115 City of Orange. 2020.

high school students.122 The increase of students as a result of the proposed project would be approximately 0.1 percent of the district’s capacity. Therefore, OUSD has the ability to accommodate the school sites demand of the proposed project as the schools that would be affected by the proposed project are below enrollment capacity.
The proposed project would pay Developer Impact Fees of $3.79 per square foot of habitable space over 499 square feet for residential development, and $0.61 per square foot for commercial development.123 Payment of the fees would satisfy the requirements of AB 2926 and SB 50 to offset impacts to school services. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (iv) Parks?
A significant impact to parks would occur if implementation of a project includes a new or physically altered park or creates the need for a new or physically altered park, the construction of which could cause substantial adverse physical impacts.
The City of Orange Community Services Department oversees 24 parks (251 acres) and over 15 miles of equestrian, biking, and recreation trails that connect a large number of neighborhood and community parks. Parks and open space make up 31.8 percent of the land use in the City.
According to the General Plan Update Program EIR, the City currently provides approximately
1.81 acres of parkland per 1,000 persons. The City anticipates developing approximately 43.5 acres of planned future parks.124
The City of Orange has a goal of providing 3 acres of parkland per 1,000 residents by 2030. 125
According to the City of Orange, the City parks most likely to be used by residents of the proposed project as open recreational space would be El Camino Real Park, located 2.7 miles northeast of the project site; Hart Park, located 3.6 miles east of the project site; and the Santiago Creek Bike Trail, located 2.7 miles east of the project site. However, with nearby freeway access, residents would have the opportunity to utilize the City’s entire park system. The City has one centrally located sports center and gymnasium at Grijalva Park and one dog park at Yorba Park. There are 122 Standard student generation factors provided by OUSD per each dwelling unit are 0.116 elementary school students, 0.013 middle school students, and 0.032 high school students (refer to Appendix J). 123 Guerra, Ymisserah.

also reservable community centers at Handy, Olive, Shaffer, and Steve Ambriz Memorial Parks.
These parks and centers are all in good condition, according to the City of Orange. 126
According to the City of Orange, the proposed project would not present any potential challenges to the park system, and the City can accommodate the proposed project’s added demand on parks.
Additionally, Municipal Code Section 16.60.050, Standards and Formula for Land Dedication, state that the City requires the payment of in lieu fees for the dedication of park land, or the dedication of parkland based upon the cost of three acres of parkland per 1,000 persons. The proposed project would be required to pay the City’s Parks and Recreational Facilities Development Impact Fee of $11,542 per dwelling unit.127 Payment of the fees and provision of onsite recreational amenities would offset the proposed project’s demand to public park facilities.
Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (v) Other public facilities?
A significant impact may occur if a project includes substantial employment or population growth that could generate a demand for other public facilities, such as libraries, which would exceed the capacity to service the project site. The City’s public libraries operate according to the Public Library Facilities Master Plan (2002–2020). This master plan outlines current and projected future demand based on General Plan buildout. The master plan ensuresthat the California State Library’s recommended standard of four volumes and 0.7 square foot per capita is maintained, and that the City’s library service needs are met as future development occurs.
The nearest library within the City’s library system is the Orange City Public Library main library, located at 407 East Chapman Avenue, 4.1 miles east of the project site. During the development phase of the proposed project, the developer would be required to comply with the requirements of the Municipal Code, including payment of the required library facilities fee, as outlined in Chapter 3.50 (Library Facilities Fees) of the Municipal Code.128 With payment of the required library fees, the proposed project would result in a less than significant impact to libraries. In addition, the proposed project would result in less than significant impacts to other public facilities in the area. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. 126 Hagan, Bonnie. Assistant City Manager/Community Services Director, City of Orange. Personal communication: email.

(a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?
A significant impact may occur if a project would include substantial employment or population growth, which could generate an increased demand for public park facilities that exceeds the capacity of existing parks and causes premature deterioration of the park facilities. New residents may result in increased use of existing City and regional parks, other recreational facilities, and trails, which may cause or accelerate substantial physical deterioration of these facilities and/or require construction of new facilities.
The proposed project would include the demolition of an existing commercial building and construction of an up to 6-story, 225-unit apartment building. The existing commercial building does not currently provide any housing units and therefore does not currently support a residential population. Therefore, the proposed project would have the potential to increase the use of existing neighborhood and regional parks due to population growth. The nearest parks include El Camino Real Park, Hart Park, and the Santiago Creek Bike Trail.
The City of Orange Community Services Department oversees 24 parks consisting of about 251 acres of parkland, and the current park acreage equates to 1.81 acres of parkland per 1,000 persons.
Parks and open space comprise 31.8 percent of the land use in the City.129 The City also oversees over 15 miles of recreational trails and over 30 miles of bikeways. 130,131 The City’s goal is to provide 3 acres of parkland per 1,000 residents.132

pay the Parks and Recreational Facilities Development Impact Fee of $11,542 per dwelling unit.
Additionally, the proposed project would offset some demand for public recreational facilities by providing recreational amenities for residents on-site, such as outdoor courtyards with seating areas, lounge seating, firepits, swimming pool, spa, and a barbecue counter. Therefore, the proposed project would not cause the deterioration of neighborhood or regional parks or other public facilities. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?
A significant impact may occur if a project includes the construction or expansion of recreational facilities, and if such construction of these facilities would have a significant adverse effect on the environment. The proposed project would provide residents with on-site indoor and outdoor private recreational facilities, including two outdoor courtyards with seating areas, lounge seating, firepits, raised planters, a pool and spa, overhead shade, and a barbecue counter, as well as a 3,628- square-foot fitness center.
Construction of the proposed project would not result in a construction-related or operational impact related to the provision of recreational facilities. Therefore, impacts would be less than significant.

(d) Result in inadequate emergency access?
Environmental Setting
A TIA and a VMT Assessment were prepared for this project by LLG on December 11, 2020 (Revised September 21, 2022), and included in this IS/MND as Appendix K-1. It should be noted that the TIA conservatively evaluates the development of 226 apartment units and 9,169 square feet of retail uses, even though the project as currently proposed would develop 225 apartment units and 9,000 square feet of retail uses. Thus, this conservative analysis evaluates the worst-case scenario.
Impact Analysis
Would the project:
(a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? The TIA satisfies the traffic impact requirements of the City of Orange and Caltrans and is consistent with the most current Orange County Congestion Management Program (CMP).
Changes to the CEQA Guidelines were adopted in December 2018 to implement SB 743.
Guideline 15064.3, which describes criteria for evaluating a project's transportation impacts, provides that VMT is generally "the most appropriate measure of transportation impacts," and that except for roadway capacity projects, a project's effect on traffic delays "shall not constitute a significant environmental impact." These provisions went into effect July 1, 2020. While Guideline 15064.3 governs a lead agency's assessment of traffic impacts under CEQA, it does not preclude a discussion of Level of Service (LOS)-based analysis for informational purposes or other traffic analysis based on general plan, zoning standards, or the policies of other agencies.
The TIA addressed the potential traffic impacts and circulation needs and is included for informational purposes. The TIA evaluated the existing operating conditions at six key study intersections, two existing project driveways, and four key roadway segments within the project vicinity, estimated the trip generation potential of the proposed project, forecasted future operating conditions without and with the proposed project, and identified appropriate intersection improvements and mitigation measures.
153
The TIA analyzed existing and future weekday daily, AM peak-hour, and PM peak-hour traffic conditions for a near-term (Year 2024) traffic setting upon completion of the proposed project.
Daily and peak-hour traffic forecasts for the Year 2024 horizon year have been projected by increasing existing traffic volumes by an annual growth rate of 1 percent per year and adding traffic volumes generated by 64 cumulative projects.
Study Area
Table 20 below lists the six key study intersections, two existing project driveways, and four key roadway segments that were evaluated in the TIA. Additionally, Table 20. below lists the key roadway segments evaluated in the TIA. The key study intersections and roadway segments selected for evaluation were determined based on application of the “51 or more peak-hour trip threshold” criteria outlined in the City of Orange Traffic Impact Analysis Guidelines.133 The study area intersections and roadway segments listed below provide local access to the study area and define the extent of the boundaries for the TIA. The jurisdiction where each key study intersection/roadway segment is located is also identified.

Traffic Impact Analysis Scenarios
The following scenarios are those for which volume/capacity calculations have been performed at the six key study intersections, two existing project driveways, and four key roadway segments for Existing Plus Project and Near-Term (Year 2024) traffic conditions:
• Existing Traffic Conditions;
• Existing Plus Project Traffic Conditions;
• Scenario (b) with Improvements, if necessary;
• Near-Term (Year 2024) Cumulative Traffic Conditions,
• Near-Term (Year 2024) Cumulative Plus Project Traffic Conditions; and • Scenario (e) with Improvements, if necessary.
LEVEL OF SERVICE
City of Orange
The Level of Service (LOS) estimate is a measure of the intersection performance. According to the General Plan Circulation Element, LOS characterizes traffic congestion on a scale of A to F with LOS A representing a free-flow condition and LOS F representing extreme congestion. LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all intersections, and LOS D is the minimum acceptable condition that should be maintained on a daily basis on all roadway segments.134 City of Garden Grove
According to the City of Garden Grove, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all intersections, and LOS D is the minimum acceptable condition that should be maintained on a daily basis on all roadway segments.
City of Santa Ana
According to the City of Santa Ana, LOS D is the minimum acceptable condition that should be maintained for all intersections and roadway segments. However, the City of Santa Ana has defined exceptions to this criterion at specific locations within the City. The City of Santa Ana has defined Major Development Areas where LOS E is considered acceptable. It should be noted that all City of Santa Ana intersections and roadway segments evaluated in this traffic study (i.e., key study intersection No. 6 and key roadway segments C and D) are not designated as Major Development Areas and therefore LOS D is the minimum acceptable condition that should be maintained. 134 City of Orange. 2010.

Impact Criteria and Thresholds
City of Orange
Impacts to local and regional transportation systems located in the City of Orange are considered significant if:
Intersections
• An unacceptable peak-hour LOS at any of the key intersections is projected. According to the City’s Circulation Element and City of Orange Traffic Impact Analysis Guidelines and Level of Service Assessment, dated July 2020, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours at all intersections;135,136 and
• The project increases traffic demand at the study intersection by 1 percent of capacity (Intersection Capacity Utilization [ICU] increase 0.010) or greater, causing or worsening LOS E or LOS F (ICU > 0.900).
Roadway Segments
• An unacceptable daily LOS at any of the key roadway segments is projected. According to the General Plan Circulation Element and stated in City of Orange Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment, dated July 2020, LOS D is the minimum acceptable condition that should be maintained on a daily basis on all roadway segments;137,138 and
• The project increases traffic demand at the roadway segment by 1 percent of capacity (V/C increase 0.010), causing or worsening LOS E or LOS F (V/C > 0.900).
City of Garden Grove
Impacts to local and regional transportation systems located in the City of Garden Grove are considered significant if:
Intersections
• An unacceptable peak-hour LOS at any of the key intersections is projected. According to the City of Garden Grove, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all intersections; and
• The project increases traffic demand at the study intersection by 1 percent of capacity (ICU increase ≥0.010), causing or worsening LOS E or LOS F (ICU > 0.900). 135 City of Orange. 2010. Orange General Plan: Circulation and Mobility Element. https://www.cityoforange.org/home/showpublisheddocument/192/637698172525970000. Accessed August 18, 2022. 136 City of Orange. 2007.

Roadway Segments:
• An unacceptable daily LOS at any of the key roadway segments is projected. According to the City of Garden Grove, LOS D is the minimum acceptable condition that should be maintained on a daily basis on all roadway segments; and • The project increases traffic demand at the roadway segment by 1 percent of capacity (V/C increase ≥ 0.010), causing or worsening LOS E or LOS F (V/C > 0.900).
City of Santa Ana
Impacts to local and regional transportation systems located in the City of Santa Ana are considered significant if:
Intersections:
• An unacceptable peak-hour LOS at any of the key intersections is projected. The City of Santa Ana considers LOS D (ICU = 0.801-0.900) to be the minimum acceptable LOS for all intersections, except for those locations located within the City’s defined Major Development Areas, where LOS E is considered acceptable. It should be noted that all City of Santa Ana intersections evaluated in this traffic study (i.e., key study intersection No. 6) are not designated as Major Development Areas and therefore LOS D is the minimum acceptable condition that should be maintained. • The project increases traffic demand at the study intersection by 1 percent of capacity (ICU increase ≥ 0.010), causing or worsening LOS E or LOS F (V/C > 0.900).
Roadway Segments:
• According to the City of Santa Ana, LOS D is the minimum acceptable condition that should be maintained for all roadway segments, except for those locations located within the City’s defined Major Development Areas, where LOS E is considered acceptable. It should be noted that all City of Santa Ana roadway segments evaluated in this traffic study (i.e., key roadway segments C and D) are not designated as Major Development Areas and therefore LOS D is the minimum acceptable condition that should be maintained.
• The project increases traffic demand at the roadway segment by 1 percent of capacity (V/C increase ≥ 0.010), causing or worsening LOS E or LOS F (V/C > 0.900).
LOS Methodology for Future Impacts
The ICU methodology is used to assess the operation of the signalized study area intersections within the jurisdiction of the City of Orange. Study area intersections that are stop sign controlled have been analyzed using the Highway Capacity Manual (HCM) methodology. Additionally, signalized study area intersections that are in shared jurisdiction of the City of Orange, City of Garden Grove, City of Santa Ana, and Caltrans have been analyzed using the HCM methodology as well as the ICU methodology.

Project Traffic Trip Generation
Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular movements, either entering or exiting the generating land use. Generation equations and/or rates used in the traffic forecasting procedure are found in the 10th Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE). The trip generation potential of the proposed project was estimated using ITE Land Use 221: Multi-family Housing Mid-Rise trip rates and ITE Land Use 820: Shopping Center equations.
The proposed project is expected to generate approximately 2,091 daily trips, with 219 trips (107 inbound, 112 outbound) produced in the AM peak-hour and 147 trips (82 inbound, 65 outbound) produced in the PM peak-hour on a typical weekday. The existing land use generates approximately 1,052 daily trips, with 140 trips (87 inbound, 53 outbound) produced in the AM peak-hour and 60 trips (29 inbound, 31 outbound) produced in the PM peak-hour on a typical weekday. With application of existing trip credits, the proposed project is forecast to generate a net of 1,039 daily trips, a net of 79 AM peak-hour trips, and a net of 87 PM peak-hour trips.
The Existing Plus Project traffic conditions have been generated based upon existing conditions and the estimated project traffic. Table 22 below presents the projected AM and PM peak-hour traffic generation at the six key study intersections and the two existing project driveways with the addition of the trips generated by the proposed project to existing traffic volumes. It should be noted that the TIA conservatively evaluates the development of 226 apartment units and 9,169 square feet of retail uses, even though the project as currently proposed would develop 225 apartment units and 9,000 square feet of retail uses. Thus, this conservative analysis evaluates the worst-case scenario.

Existing Conditions
Based on results of the analysis in the TIA, all of the existing roadway segments currently operate at an LOS A, which is an acceptable LOS. Additionally, all of the State-controlled study intersections currently operate at an acceptable LOS C, which is an acceptable LOS, during the AM and PM peak-hours.
One of the study area intersections, Lewis Street at Garden Grove Boulevard, currently operates at an LOS F during the PM peak-hour, which is an unacceptable LOS.
Existing Plus Project Traffic Conditions
The TIA indicates that traffic associated with the proposed project would not significantly impact any of the six key study intersections or either of the two State-controlled study intersections when compared to the LOS standards and impact criteria. Although the intersection of Lewis Street at Garden Grove Boulevard is forecast to operate at an unacceptable LOS F during the PM peak-hour 159
with the addition of project traffic, the proposed project is expected to add less than the allowable threshold to the ICU value.
The remaining five key study intersections currently operate and are forecast to continue to operate at an acceptable LOS D or better during the AM and PM peak-hours with the addition of projectgenerated traffic to existing traffic under this scenario. The two State-controlled study intersections are forecast to continue to operate at an acceptable LOS C with the addition of project-generated traffic to existing traffic.
Additionally, the TIA indicates that traffic associated with the proposed project would not significantly impact any of the four key roadway segments when compared to the LOS standards and impact criteria. The four key roadway segments currently operate and are forecast to continue to operate at an acceptable service level on a daily basis with the addition of project-generated traffic to existing traffic under this scenario.
Near-Term (Year 2024) Cumulative Traffic Conditions
The TIA indicated that the addition of ambient traffic growth and cumulative project traffic would adversely impact two of the six key study intersections. The remaining four key study intersections are forecast to continue to operate at acceptable LOS during the AM and PM peak-hours with the addition of ambient traffic growth and cumulative project traffic. Additionally, the two Statecontrolled study intersections are forecast to continue to operate at acceptable LOS C during the AM and PM peak-hours with the addition of ambient traffic growth and cumulative projects traffic.
The key study intersections forecast to operate at an adverse LOS are as follows:
1. Lewis Street at Garden Grove Boulevard
2. Bristol Street at Memory Lane
The TIA indicated that future (Year 2024) cumulative traffic conditions at the four key roadway segments are forecast to continue to operate at acceptable LOS on a daily basis with the addition of ambient traffic growth and cumulative projects traffic. The analysis for Memory Lane between The City Drive and Bristol Street included the planned reduction of lanes from six lanes to four lanes, in order to accommodate plans for a bike lane in each direction.
Near-Term (Year 2024) Cumulative Plus Project Traffic Conditions The TIA indicated that traffic associated with the proposed project would not significantly impact any of the six key study intersections or either of the two State-controlled study intersections when compared to the LOS standards and impact criteria. Although the intersections of Lewis Street at Garden Grove Boulevard and Bristol Street at Memory Lane are forecast to operate at an unacceptable LOS E or LOS F during the AM and/or PM peak-hours with the addition of project traffic, the proposed project is expected to add less than the allowable threshold to the ICU value.
The remaining four key study intersections currently operate and are forecast to continue to operate at an acceptable LOS D or better during the AM and PM peak-hours with the addition of project- 160
generated traffic under this scenario. The two State-controlled study intersections are forecast to continue to operate at acceptable LOS C with the addition of project-generated traffic in the Year 2024.
The TIA indicated that the proposed project would not significantly impact any of the four key roadway segments. The four key roadway segments are forecast to continue to operate at acceptable service levels on a daily basis with the addition of project-generated traffic under this scenario.
As stated in the TIA, the proposed project is not anticipated to result in a significant impact on the study area intersections or roadway segments under existing and future traffic conditions based on the City of Orange, City of Garden Grove, and City of Santa Ana standards and significance criteria. Although some study area intersections currently operate at unacceptable LOS as described above, the proposed project is expected to add less than the allowable threshold to the ICU value, and therefore, the proposed project’s contribution would be less than significant.
Transit, Bicycle and Pedestrian Facilities
The project site is located 125 feet north of a bus stop for Bus Route 56, Garden Grove to Orange,139 located at the southwest corner of the intersection of Garden Grove Boulevard and The City Drive South. Additionally, a stop for Bus Route 57, Brea to Newport Beach, is located 110 feet east of the project site.140 Both bus stops are accessible from the site via crosswalks on Garden Grove Boulevard and The City Drive South. Additionally, a bus stop for Bus Routes 47 and 47A, Fullerton to Balboa, are located at the intersection of South Lewis Street and Garden Grove Boulevard, 0.35 mile west of the project site.141
The proposed project would include a pedestrian-friendly design including a widened sidewalk and streetlights for pedestrians. The project site is located 350 feet west of the Santa Ana River Trail and Bikeway, which is a multiuse paved trail that runs parallel to the Santa Ana River and will run 110 miles when finished.142 Additionally, according to the TIA, future bike lanes are planned along Memory Lane, which is east of The City Drive South and Garden Grove Boulevard, 135 feet southeast of the project site. The proposed project would not result in any adverse impacts to public transit, bicycle, or pedestrian facilities.
Impact Conclusion
The proposed project would not conflict with any applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system, such as the City of Orange Circulation and Mobility Element or the Orange County Congestion Management Plan.

proposed project would result in less than significant impacts on traffic/circulation and the surrounding roadway network, and no mitigation is required. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3 subdivision (b)?
Section 15064.3 of the CEQA Guidelines provides specific considerations for evaluating a project’s transportation impacts. Per Section 15064.3, analysis of VMT attributable to a project is the most appropriate measure of transportation impacts. Other relevant considerations may include the effects of the project on transit and non‐motorized travel. Except as provided in Section 15064.3(b)(2) regarding roadway capacity, a project’s effect on automobile delay does not constitute a significant environmental impact under CEQA.
The City of Orange adopted transportation impact criteria in July 2020 to be consistent with the CEQA revisions. As part of the updated guidelines, the City of Orange has developed a VMT Traffic Study Screening Tool to be utilized by proposed development projects. The details of the proposed project (i.e., location, project land use information, etc.) are provided to City of Orange Traffic Engineering staff and entered into the screening tool to determine whether or not a project will require a VMT analysis.
There are three types of screening that may be applied to effectively screen projects from projectlevel assessment. These screening steps are summarized below.
Step 1: Transit Priority Area Screening
Projects located within a Transit Priority Area (TPA), defined as an 0.5-mile area around an existing major transit stop or an existing stop along a high-quality transit corridor, may be presumed to have a less than significant impact absent substantial evidence to the contrary. This presumption may NOT be appropriate if the project:
1. Has a FAR of less than 0.75;
2. Includes more parking for use by residents, customers, or employees of the project than required by the City;
3. Is inconsistent with the applicable SCS (as determined by the lead agency, with input from SCAG); or
4. Replaces affordable residential units with a smaller number of moderate- or high-income residential units.
162
Step 2: Low VMT Area Screening
Residential and office projects located within a low VMT generating area may be presumed to have a less than significant impact absent substantial evidence to the contrary. In addition, other employment-related and mixed-use land use projects may qualify for the use of screening if the project can reasonably be expected to generate VMT per resident, per worker, or per service population that is similar to the existing land uses in the low VMT area.
Step 3: Project Type Screening
Some project types have been identified as having the presumption of a less than significant impact. The following uses can be presumed to have a less than significant impact absent substantial evidence to the contrary as their uses are local serving in nature. The project types that qualify for this screening threshold are provided in the City of Orange TIA Guidelines.143 According to the VMT Assessment (Appendix K-2), the proposed project is in a low VMT generating zone, which meets the criteria for Project Screening – Step 2: Low VMT Area Screening. Because the Project Screening – Step 2: Low VMT Area Screening was applied, the proposed project can be screened from further VMT analysis. Additionally, the proposed project falls well below the existing VMT per service population. The proposed project would have 21.6 VMT per service population, which is below the existing VMT of 31.5 per service population.
Based on the screening criteria, the proposed project can be screened from further VMT analysis, and the proposed project can be presumed to have a less than significant impact on VMT, per the City’s guidelines. Therefore, the proposed project would not conflict or be inconsistent with CEQA Guidelines Section 15064.3 subdivision (b). There would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (c) Substantially increase hazards due to a geometric design feature (e. g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? A significant impact may occur if a project were to include a new roadway design, introduce new land use or project features into an area with specific transportation requirements and characteristics that have not been previously experienced in that area, or if project access or other features were designed in such a way as to create hazardous conditions.
According to the site access evaluation provided in the TIA, access to the project site would continue to be provided via one full-access driveway located along The City Drive, and one right143 City of Orange. 2020.

in-/right-out driveway located along Garden Grove Boulevard, both of which are shared with the adjacent office complex.
The intersection of The City Drive and Existing Driveway No. 1 currently operates at an unacceptable LOS during the AM and PM peak-hours. Additionally, the intersection of Existing Driveway No. 2 and Garden Grove Boulevard currently operates at an acceptable LOS C or better during the AM and PM peak-hours. The proposed project would cumulatively impact the intersection of The City Drive and Existing Driveway No. 1. The intersection of City Drive and Existing Driveway No. 1 is forecast to operate in the Year 2024 at unacceptable LOS F during the AM and PM peak-hours. The intersection of Existing Driveway No. 2 and Garden Grove Boulevard is forecast to operate in the Year 2024 at an acceptable LOS C or better during the AM and PM peak-hours. An intersection operating at an unacceptable LOS could result in unsafe transportation conditions to vehicles and pedestrians.
MM TRANS-1 would require the installation of a five-phase traffic signal to minimize the impacts of the proposed project. It should be noted that the peak-hour traffic signal warrant is satisfied under existing PM peak-hour traffic conditions. With implementation of MM TRANS-1, the intersection of The City Drive and Existing Driveway No. 1 is forecast to operate at an acceptable LOS A during the AM and PM peak-hours. As such, project access would be adequate. With implementation of MM TRANS-1, motorists entering and exiting the project site would be able to do so comfortably, safely, and without undue congestion. Therefore, potentially significant impacts would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact.
Mitigation Measures:
MM TRANS-1 The City Drive at Existing Driveway No. 1: The Applicant shall install a five-phase traffic signal with protected left-turn phasing in the northbound and southbound directions and permissive phasing in the eastbound and westbound directions. The installation of this improvement shall be subject to approval by the City of Orange. Although this location is cumulatively impacted by the proposed project, based on coordination with City of Orange Traffic Engineering staff, the proposed project shall be 100 percent responsible for the design, engineering and construction of the recommended traffic signal at this location. It shall be noted that the peak hour traffic signal warrant is satisfied under existing PM peak hour traffic conditions.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
164
(d) Result in inadequate emergency access?
The TIA included a site access evaluation. According to the TIA, implementation of MM TRANS1 would ensure that motorists entering and exiting the project site would be able to do so comfortably, safely, and without undue congestion.
Furthermore, as discussed in Section 5.9, Hazards and Hazardous Materials, the proposed project does not include street closures and therefore would not affect emergency access to The City Drive evacuation corridor. Construction and internal circulation would comply with the applicable fire codes as required by the OCFD. The site plans would be reviewed and approved by the Orange Building and Fire Departments to ensure adequate emergency access. Implementation of the proposed project during construction and operational would not impair or physically interfere with the City’s Emergency Operation Plan, the General Plan Safety Element, or any other emergency response plan. Therefore, the proposed project would not affect emergency access. Potentially significant impacts would be less than significant with mitigation incorporated.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM TRANS-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.

Impact Analysis
(a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects?
A significant impact may occur if a project would increase water consumption or wastewater generation to such a degree that the capacity of facilities currently serving the project site would be exceeded. The proposed project would be served by the Orange County Sanitation District (OC San) and the City of Orange Public Works Water Division. The Public Works Water Division provides potable water from two main sources, including about 75 percent from groundwater sources managed by the OCWD. The City also imports water from the Metropolitan Water District of Southern California through the Municipal Water District of Orange County.144 Based on the 2015 Urban Water Management Plan (UWMP), the baseline water use is 224 gallons per capita per day (GPCD).145 The proposed project would introduce an estimated an estimated 697 residents based on the City of Orange average household size of 3.08 persons.146 Based on the estimated number of residents, water demand for the proposed project would be 156,352 gallons per day, or approximately 175.14 acre-feet per year.

predicts a total Citywide water demand of 29,500 acre-feet per year by 2025. 147 The proposed
project’s anticipated water usage would represent a nominal 0.006 percent increase in water demand in the City.
Water Treatment System
The City of Orange Public Works Water Division provides potable water service (which includes imported water, groundwater, and surface water) to land uses within the City and would provide potable water for the uses under the proposed project. Water imported by the Metropolitan Water District of Southern California is treated at the Robert Diemer Filtration Plant in the City of Yorba Linda, which has capacity of 520 million gallons per day.148 Water treatment facilities filter and/or disinfect water before it is delivered to customers. Based on the capacity of the Robert Diemer Filtration Plant, which is 520 million gallons per day, the proposed project’s water demand of 156,352 gallons per day would be only 0.03 percent of the daily capacity. Therefore, there is adequate water treatment capacity in the region for the proposed project’s projected water demand.
Therefore, the proposed project would not require the relocation or construction of new or expanded water treatment facilities. Impacts related to water would be less than significant.
Wastewater Treatment System
A sewer capacity analysis was prepared for the project on February 12, 2021, by Fuscoe Engineering, and is included as Appendix L of this IS/MND. Note that the sewer capacity analysis is based on a larger study area than what is currently proposed. The analysis includes the build-out of a stand-alone parking structure previously contemplated in the northern portion of the 5.86-acre site, which is no longer part of the proposed project. Thus, this conservative analysis evaluates the worst-case scenario.
There is an existing 8-inch on-site sewer to which the proposed project would connect. This onsite sewer connects to an existing 8-inch public sewer along Garden Grove Boulevard to the south that flows westerly. According to the sewer capacity analysis, the existing wastewater generation is 0.0751 million gallons per day (mgd). With the proposed land uses, the sewage generation would increase to 0.0973 mgd. The analysis indicates that increased wastewater generated by the proposed project would be less than the intended design flows can accommodate; therefore, the existing sewer infrastructure would be able to accommodate the wastewater generated by the proposed project.
OC San is responsible for the collection, treatment, and disposal of domestic, commercial, and industrial wastewater generated by people living and working in central and northwestern Orange County. OC San has two operating facilities that treats municipal, commercial, and industrial sewage, removing contaminants before sending the water to OCWD for the Groundwater 147 City of Orange.

Replenishment System (GWRS) for reuse or before releasing to the ocean.149 These include Reclamation Plant No. 1 in the City of Fountain Valley and Treatment Plant No. 2 in the City of Huntington Beach. Both plants provide a mix of advanced primary and secondary treatment. OC San is required by federal and State law to meet applicable standards of treatment plant discharge requirements, including NPDES Permit No. CA0110604 issued by the Santa Ana RWQCB in 2012 under Order No. R8-2012-0035. The NPDES permit regulates the amount and type of pollutants that the system can discharge into receiving waters. OC San’s wastewater treatment system is currently operating and would continue to operate in compliance with State waste discharge requirements and federal NPDES permit requirements as set forth in the NPDES permit and order.
OC San Plant No. 1, located in Fountain Valley, has a secondary treatment capacity of 182 mgd for Average Daily Flow (ADF), and 274 mgd for Peak Wet Weather Flow (PWWF). OC San Plant No. 2, located in Huntington Beach, has a secondary treatment capacity of 150 mgd for ADF and 317 mgd for PWWF. Together, the two plants currently treat approximately 185 mgd from approximately 2.5 million people in north and central Orange County. 150 The proposed project
would generate 0.0973 mgd, which is approximately 0.03 percent of the combined treatment capacity of the wastewater treatment plants. Therefore, the wastewater treatment system has the available capacity to accommodate the proposed project’s wastewater generation. Therefore, the proposed project would not result in the relocation or construction or expansion of wastewater treatment facilities. Impacts would be less than significant.
Stormwater Drainage
As discussed in Section 5.10, Hydrology and Water Quality, the proposed project would comply with the City of Orange Stormwater LIP151 and would prepare and implement a SWPPP and BMPs.
Additionally, the proposed project would implement MM GEO-1. Stormwater drainage would be conveyed via a proposed curb, gutter, and storm drain system. Flows beyond the capture efficiency volume would bypass the system and discharge directly to the Santa Ana River via the proposed private and existing public storm drain system. According to the WQMP, the proposed project would decrease impervious surfaces and increase infiltration capacity as compared to existing conditions.152 Therefore, the proposed project would not substantially increase stormwater drainage such that new or expanded facilities or relocation would be required. Impacts would be less than significant.

Electric Power
The proposed project would connect to the City’s existing electrical infrastructure and would be served by SCE. Impacts associated with electricity required by the proposed project are discussed in further detail in Section 5.6, Energy. Impacts were concluded to be less than significant.
Natural Gas
Natural gas services to the project site would be provided by SCE. Impacts associated with natural gas required by the proposed project are discussed in further detail in Section 5.6, Energy. Impacts were concluded to be less than significant.
Telecommunications
Charter Communications would provide cable service to the proposed project. The proposed project would connect to the existing telecommunications infrastructure. Therefore, the proposed project would not require the installation or development of new or improved telecommunications facilities such that environmental impacts would occur. Impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? A significant impact may occur if a project were to increase water consumption to such a degree that new water sources would need to be identified, or that existing resources would be consumed at a pace greater than planned for by purveyors, distributors, and service providers. A forecast of the City of Orange water supplies and water demands in normal, dry, and multiple dry year conditions from 2020 through 2040 are listed in the City’s most current UWMP. According to the UWMP, the available supply would meet projected demand due to diversified supply and conservation measures. By 2025, the City would have both a supply and demand of 31,270 acrefeet of water during a multiple dry year scenario.153 The proposed project’s anticipated demand of 175.14 acre-feet per year would be 0.56 percent of the available supply. However, the estimated water demand for the proposed project does not take into account the water-saving measures that the City would require in order to achieve a water reduction target. Therefore, the City would have the available water supply to serve the proposed project, and development of the proposed project would not require the City of Orange to obtain new or expanded water facilities. Impacts would be less than significant. 153 City of Orange. 2016. 2015 Urban Water Management Plan, Final. June. Website:

Significance Determination After Mitigation: Less than significant impact. (c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
A significant impact may occur if a project would increase wastewater generation to such a degree that the capacity of facilities currently serving the project site would be exceeded. As discussed previously, the wastewater treatment system has the available capacity to accommodate the proposed project’s wastewater generation. Therefore, impacts would be less than significant.
Significance Determination: Less than significant impact.
Mitigation Measures: None.
Significance Determination After Mitigation: Less than significant impact. (d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? A significant impact may occur if a project were to increase solid waste generation to a degree that existing and projected landfill capacity would be insufficient to accommodate the additional solid waste. Trash, recyclables, and organic waste within the City are collected by CR&R Waste and Recycling Services.154 Trash is disposed at any of the three facilities in Orange County: Olinda Alpha Landfill in Brea, Frank R. Bowerman Landfill in Irvine, and Prima Deshecha Landfill in San Juan Capistrano.155 Recyclables and organic waste are process by CR&R.
According to the General Plan EIR, the waste generation rate for mixed-use residential components is 7.9 pounds per dwelling unit per day.156 The proposed project would have 225 residential units. According to this waste generation rate, the proposed project would generate 1,777.5 pounds (0.89 tons) of solid waste per day.
The Olinda Alpha Landfill is permitted to receive a daily maximum of no more than 8,000 tons per day of solid waste. The total amount of solid waste (0.89 tons) generated by the proposed project would be only 0.01 percent of the landfill’s daily capacity. Additionally, waste diversion and public education programs can potentially reduce the amount of solid waste at the source before making it to landfills. Although the proposed project would increase demand for solid waste services by generating additional solid waste, the existing landfills have sufficient capacity to accommodate the proposed project.

The proposed project would be served with recycling and organic waste services provided by the City of Orange and would comply with applicable statutes associated with solid waste and solid waste reduction. Therefore, there would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. 171

(d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Impact Analysis
(a) Substantially impair an adopted emergency response plan or emergency evacuation plan?
As discussed in Section 5.9, Hazards and Hazardous Materials, the City has an EOP that establishes emergency preparedness and emergency response procedures. The proposed project would be adequately served by police, fire, and emergency response services, including respective evacuation or emergency vehicle access. The project site would be served by the OCFD. The proposed project would comply with fire safety standards of the Municipal Code and the Orange Fire Code, which has adopted by reference the California Fire Code, 2019 Edition.157 The proposed project would not impair an adopted emergency response plan or emergency evacuation plan, including the City’s EOP. Fire emergency evacuation routes are mapped in the eastern portion of the City of Orange, where wildfires are the greatest risk. There are 10 evacuation areas that are mapped in this area.
158 The project site is not included in one of the 10 evacuation areas; however, Chapman Avenue, located 1.1 miles north of the project site, is designated as a fire evacuation route.
159 In the very unlikely event of an evacuation due to wildland fires, project occupants would have access to the Chapman Avenue emergency evacuation route via The City Drive South or via Garden Grove Boulevard west to Lewis Street. The proposed project would not interfere with any evacuation routes during construction or operation of the project. Therefore, there would be no impacts related to emergency response and evacuation plan consistency. 157 City of Orange. Orange Municipal Code Chapter 15.32 – City of Orange Fire Code. Website:

Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (b) Due to slope prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose Project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
The proposed project is in an urbanized area and is surrounded by a mix of residential and commercial uses. The project site is currently developed with a commercial building and parking lots and is not in an area at risk of wildland fires. According to CAL FIRE, the project site is not located within or adjacent to a Fire Hazard Severity Zone.160 The nearest Fire Hazard Severity Zone is in Villa Park, California, 5.31 miles northeast of the project site.
Additionally, according to the General Plan Public Safety Element, wildland fires are most problematic along the wildland-urban interface, the area between residential development and open grassland and vegetation along hillsides.161 The proposed project is not located in or near an area that is at risk of wildfire hazards as designated by the General Plan Public Safety Element.
Therefore, the proposed project would not exacerbate wildfire risks and expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of wildfire. There would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.
Significance Determination After Mitigation: No impact. (c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? The proposed project would consist of construction of a multi-family apartment building in an urbanized area on a site that is currently developed with a commercial building and parking lot.
As such, the proposed project may require the installation of new infrastructure and utilities to the site. The new infrastructure would be constructed in compliance with all applicable regulations and approvals, including the California Building and Fire Code and Municipal Code Chapter 15.32 –City of Orange Fire Code. Therefore, the proposed project would not exacerbate fire risks upon compliance with applicable regulations, and there would be no impacts. 160 California Department of Forestry and Fire Protection (CAL FIRE). 2020.

Significance Determination After Mitigation: No impact. (d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes?
The proposed project would not expose people or structures to significant risks, such as downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. As discussed previously, the proposed project is not located in an area at risk of wildfires as mapped by CAL FIRE162 or by the General Plan.163 Additionally, the project site is flat and is not near any slopes. Therefore, the project site would not be at risk of downstream or downslope flooding, landslides, or drainage changes associated with wildfire, and would not be at risk of postfire slope instability. There would be no impacts.
Significance Determination: No impact.
Mitigation Measures: None.

(a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
(b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?)
(c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
Impact Analysis
(a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
A significant impact may occur if a project would have an identified potentially significant impact for any of the above issues.
As described previously, the area surrounding the project site is characterized by extensive urban development and contains limited areas of naturally occurring habitats, and with mitigation incorporated, the proposed project would not have a substantial adverse effect on a riparian or wildlife populations, communities, or habitat, and would not conflict with any policies or ordinances protecting biological resources. The project site has the potential to support birds that are protected by the MBTA as well as to support nesting of several raptor species. Incorporation of MM BIO-1 would ensure that the proposed project would not violate the provisions of the MBTA.
Additionally, as described previously, the proposed project would not cause a substantial adverse change in the significance of a historical resource because there are no historical resources within
0.5 mile of the project site. The proposed project has a low potential to result in the inadvertent discovery of previously unknown buried archaeological resources or previously undiscovered human remains. Incorporation of MM CUL-1, MM CUL-2, MM TCR-1, MM TCR-2, and MM 175
TCR-3 would ensure that impacts are reduced to less than significant in the event that previously unknown archaeological resources or human remains are inadvertently discovered.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM BIO-1, MM CUL-1, MM CUL-2, MM TCR-1, MM TCR-2, MM TCR-3.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?) A significant impact may occur if a project, in conjunction with other related projects in the area surrounding the project site, would result in impacts that are less than significant when viewed individually, but would be significant when viewed together.
The proposed project would result in potentially significant project-specific impacts to biological resources, cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, and transportation. However, mitigation measures have been identified that would reduce these impacts to less than significant levels. Furthermore, the TIApresented herein included an analysis of cumulative impacts and determined that the potentially significant cumulative impacts would be less than significant with mitigation incorporated. No additional mitigation measures beyond those previously identified in this IS/MND would be required to reduce cumulative impacts to less than significant levels.
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM BIO-1, MM CUL-1, MM CUL-2, MM TCR-1, MM TCR-2, MM TCR-3, MM GEO-1, MM GEO-2, MM HAZ-1, and MM TRANS-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
(c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
A significant impact may occur if a project has the potential to result in significant impacts, as discussed in the preceding sections of this IS/MND.
All potential impacts of the proposed project have been identified, and mitigation measures have been provided, where applicable, to reduce potential impacts to less than significant levels. Upon implementation of the mitigation measures, the proposed project would not result in direct or indirect substantial adverse impacts on human beings. No additional mitigation measures beyond those previously identified in this IS/MND would be required. 176
Significance Determination: Potentially significant impact.
Mitigation Measures: Implement MM BIO-1, MM CUL-1, MM CUL-2, MM TCR-1, MM TCR-2, MM TCR-3, MM GEO-1, MM GEO-2, MM HAZ-1, and MM TRANS-1.
Significance Determination After Mitigation: Less than significant impact with mitigation incorporated.
