24SCA4: Product Data
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations. 4 Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line. The factory charge for 3/8” lineset 9 oz.(266.16 g). When using other length or diameter liquid lines, charge adjustments are required per the chart above.
Charging Formula:
[(Lineset oz/ft X total length) – (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of lineset* using existing 1/4“ liquid line. What charge adjustment is required? Formula:(.27 oz/ft X 15ft) – (9 oz) = (4.95) oz.
Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment? Formula:(.40 oz/ft. X 45ft) – (9 oz.) = 9 oz.
Net result is to add 9 oz of refrigerant to the system
NOTE: Conditions must be favorable for charging by subcooling method. Indoor temperature must be 70°F to 80°F (21°C to 27°C), and outdoor temperature must be 70°F to 100°F (21°C to 38°C). If outside these conditions, adjust charge for long linesets by weigh-in method. * When applicable. Refer to Physical Data Table in this PD and to the Installation Instructions for more information.
Long Line Applications
An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.
For Air Conditioner systems, the chart below shows when an application is considered Long Line.
Note: See Residential Piping and Long Line Guideline for details Table 3 – Refrigerant Charge Adjustments

Appendix J: Level of Service (LOS) Screening Analysis
1964
This technical memorandum provides an evaluation of the development located at 2375 North Tustin Street (APN:372-642-31) (Project), in the City of Orange. The purpose of this analysis is to determine whether a level of service (LOS) analysis would be required for the proposed Project. This memo will evaluate the proposed Project using the City of Orange Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment (LOS), July 2020.
Project Description
The existing site area is 4.235 gross acres and is fully developed and currently contains a vacant 45,676 square foot (SF) Best Buy retail store building, surface parking lot, and landscaping. The existing onsite improvements were constructed in 2007. The entire site is relatively flat and is accessible via the existing driveway to North Tustin Avenue. The proposed Project will demolish the existing structure and improvements on the Project site and then develop 71 paired and detached residences, open space/recreation, and parking. The residential structures would be three-stories in height and range in size from approximately 2,000 square foot three-bedroom units to 2,066 square foot four-bedroom units that would be developed above two-car garages for each of the units. The 71 residences on the 4.235-acre site would result in a density of 16.76 units per acre. The Project site plan is shown in Figure 1.
The Project site has a General Plan land use designation of General Commercial (GC) that allows a maximum Floor Area Ratio (FAR) of 1.0 and is zoned Limited Business Tustin Redevelopment Project Area (C-TR). The General Plan states that the GC land use designation provides for a wide range of retail and service commercial uses and professional offices. Regional shopping centers, mid- and high-rise office projects, corridor shopping districts, and neighborhood corner stores are all permitted uses. The Limited Business Tustin Redevelopment Project Area zoning designation is intended to provide for limited commercial uses for a wide variety of goods and services.
Project Trip Generation
The trip generation for the proposed Project was analyzed in accordance with the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition (2021). For the existing land use, ITE Land Use Code 863 (Electronics Superstore) was applied to represent the former Best Buy store. Although no trip credit was applied for the existing use in the LOS screening analysis, it was included to illustrate the number of trips previously generated by the site when the Best Buy was operational. Table 1 presents the trip generation for the former Best Buy store. As shown in Table 1, the Best Buy store was estimated to generate 1,875 daily trips, 16 AM peak hour trips, and 194 PM peak hour trips.
The proposed 71 dwelling units (DU) were analyzed using ITE Land Use Code 215, Single-Family Attached Housing. Table 2 presents the trip generation for the proposed Project. As shown in Table 2, the proposed To: City of Orange

2 Project is expected to generate a total of 511 daily trips, including 34 AM peak hour and 40 PM peak hour trips.
Level of Service (LOS) Screening
Based on City’s guidelines outlined on page 4, an LOS analysis is required when the project generates more than 100 total peak hour vehicle trips during either the AM or PM peak hour. As shown in Table 2, the proposed Project would be expected to generate 34 AM peak hour trips and 40 PM peak hour trips.
Therefore, per the City’s TIA Guidelines, a full LOS analysis is not required for the proposed Project.
TIA Screening Results
The proposed Project was evaluated according to the City’s TIA guidelines to determine if the Project would require an LOS analysis. The proposed Project is anticipated to generate 34 AM peak hour trips and 40 PM peak hour trips, which is below the 100 peak hour trips threshold. Therefore, a LOS analysis would not be required for the proposed Project.

2375 North Tustin Street Project VMT Analysis
1 1 EXECUTIVE SUMMARY
This Vehicle Miles Traveled (VMT) Analysis has been prepared by EPD Solutions, Inc. to analyze the potential traffic related impacts of the proposed 2375 North Tustin Street Project (Project).
Project Description
The Project site is located at 2375 North Tustin Street (Assessor's Parcel Number [APN]: 372-642-31) in the City of Orange. The existing site area is 4.235 gross acres and is fully developed with a vacant 45,676-square-foot (SF) Best Buy retail store building, surface parking lot, and landscaping. The existing on-site improvements were constructed in 2007. The entire site is relatively flat and is accessible via the existing driveway to North Tustin Avenue. The proposed Project will demolish the existing structure and improvements on the Project site and then develop 71 paired and detached residences, open space/recreation, and parking. The residential structures would be three stories in height and range in size from approximately 2,008 square to 2,117 square feet and have three or four bedrooms.
Each residence would have a two-car garage. The 71 residences on the 4.235-acre site would result in a density of 16.76 dwelling units per acre (DU/ac).
Project Trip Generation
The proposed 71 dwelling units were analyzed based on the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition (2021) as Single-Family Attached Housing. The proposed Project is expected to generate a total of 511 daily trips, including 34 AM peak hour trips and 40 PM peak hour trips.
Project VMT Screening Analysis
The City or Orange’s Guidelines provide the following screening criteria to identify if a project would be considered to have a less-than-significant impact on VMT and therefore could be screened out from further VMT analysis:
1. Is the Project within one-half mile of qualifying transit? Projects located within a Transportation Priority Area (TPA), defined as an area within one-half mile of qualifying transit, may be presumed to have a less-than-significant impact on VMT. The Project site is not located within a TPA based on the “NOCC+ (North Orange County Collaborative)” tool provided by the City of Orange that was last updated in 2021. However, the Orange County Transit Authority (OCTA) has since improved the frequency of Route 50 along N. Tustin Avenue to 15 minutes during peak hours, which became effective in November 2025. Therefore, the Project is located within a TPA under the most up-to-date transit service frequency.
While the Project is in a TPA, it does not meet all the requirements for Screening Criteria 1 since the Project provides more parking then required. Therefore, the project would not meet Screening Criteria
1. 2. Is the Project in a low VMT area?
Projects located within a low VMT-generating area that are consistent with the existing land use within that traffic analysis zone (TAZ) may be presumed to have a less-than-significant impact on VMT. The 1973
2375 North Tustin Street Project VMT Analysis
2 Project is not consistent with the existing land use. Therefore, it does not meet the requirements of Screening Criteria 2.
3. Is the Project a local serving land use?
Projects that propose local-serving land uses or generate fewer than 110 daily vehicle trips may be presumed to have a less-than-significant impact on VMT. The Project is not considered a local-serving land use and is anticipated to generate 511 daily trips, which is more than 110 daily vehicle trips.
Therefore, it does not meet the requirements of Screening Criteria 3.
The Project would not meet any of the City’s screening criteria; therefore, a full analysis of VMT was prepared for the Project.
Project-Generated VMT Evaluation
The proposed Project would develop 71 residential units on a 4.235 acre site. As defined by CAPCOA Measure T-1, “An acre in this context is defined as an acre of developed land, not including streets, school sites, parks, and other undevelopable land.” The net acreage of the site is 3.145 acres, which would result in a residential density of 22.57 units per net acre, and provides a reduction in VMT pursuant to Measure T-1: Increase Residential Density from the CAPCOA Handbook. • T-1 CAPCOA Measure T-1: Increase Residential Density. This measure accounts for the VMT reduction achieved by a project that has a higher density of dwelling units (DU) compared to the average residential density. Increased densities have been shown to affect the distance people travel and may result in greater options for the mode of travel they choose. Increasing residential density can result in shorter and fewer trips by single-occupancy vehicles. The residential density of the Project is calculated by dividing the total number of dwelling units (71 DUs) by the net acreage (3.145 acres) of the Project. Based on this, the residential density is calculated to be 22.57 units per net acre. The equation for the reduction in VMT is based on the residential density of the Project and the residential density of a typical development, or the residential density in the relevant TAZ1. o Using the residential density of TAZ 573 where the Project is located under existing conditions of 13.27 DU/ac (338 households2 in the 26.9 residential acres [25.47 net acres]3 within TAZ 573), the Project-generated VMT would be reduced by 15.4%.
With T-1 applied, the total VMT generated from TAZ 573 would reduce from 7,659 VMT to 6,479 VMT in under Base Year (2019) Conditions and 8,146 VMT to 6,890 VMT under Cumulative (2050) Conditions. The resulting Project VMT/Service Population values, would be 11.7% below the threshold under Project Baseline (2025) Conditions and 7.1% below the threshold under Cumulative (2050) 1 Per the CAPCOA Handbook, Increase Residential Density (T1), p. 71, the formula for VMT reduction is A = ((B - C) / C) × D, where A (0–30.0%) represents the percentage reduction in GHG emissions from project VMT in the study area, B (du/acre) is the residential density of the project development (dwelling units per acre), C is the residential density of a typical development (9.1 du/acre); however, the residential density of the relevant Transportation Analysis Zone (TAZ) should be used instead of this typical value, and D (-0.22) is the elasticity of VMT with respect to residential density. 2 Number of households provided by City of Orange.

3 Conditions. Therefore, the proposed Project would result in a less-than-significant Project-generated VMT impact.
Project’s Effect on VMT
A boundary method analysis was conducted to evaluate the Project’s cumulative impacts on VMT. The Orange Citywide Boundary VMT/SP is 0.02% lower with the Project added under Project Baseline (2025) conditions and 0.03% lower with the Project added under Cumulative (2050) conditions.
Therefore, the Project’s effect on VMT would be less than significant. 1975

4 2 INTRODUCTION
This Vehicle Miles Traveled (VMT) Analysis has been prepared by EPD Solutions, Inc. to analyze the potential traffic related impacts for the proposed residential development located at 2375 North Tustin Street (Project). The scope of work for this VMT analysis was reviewed and approved by the City of Orange and is provided in Appendix A. The background for this analysis and Project description are discussed in detail below.
This VMT analysis is based on the requirements of the City of Orange Transportation Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment (City’s Guidelines), adopted by the City in July 2020.
2.1 Project Description
The proposed Project site is located at 2375 North Tustin Street (Assessor's Parcel Number [APN]: 372- 642-31) in the City of Orange. The existing site area is 4.235 gross acres and is fully developed with a vacant 45,676-square-foot (SF) Best Buy retail store building, surface parking lot, and landscaping.
The existing on-site improvements were constructed in 2007. The entire site is relatively flat and is accessible via the existing driveway to North Tustin Avenue. The proposed Project will demolish the existing structure and improvements on the Project site and then develop 71 paired and detached residences with open space/recreation and parking. The residential structures would be three stories in height and range in size from approximately 2,008 square feet to 2,117 square feet and would have three or four bedrooms (57 three-bedroom units and 14 four-bedroom units). Each residence would have a two-car garage. The 71 residences on the 4.235-acre site would result in a density of 16.76 dwelling units per acre (DU/ac) and a floor area ratio (FAR) of 0.79. The proposed Project site plan is shown in Figure 1.
The Project site currently has a General Plan land use designation of General Commercial (CG) that allows a maximum FAR of 1.0 and is zoned Limited Business Tustin Redevelopment Project Area (C-TR).
The General Plan states that the GC land use designation provides for a wide range of retail and service commercial uses and professional offices. Regional shopping centers, mid- and high-rise office projects, corridor shopping districts, and neighborhood corner stores are all permitted uses. The Limited Business Tustin Redevelopment Project Area zoning designation is intended to provide for limited commercial uses for a wide variety of goods and services.
The Project includes a General Plan Amendment to change the land use from GC to Medium Density Residential (MDR), which allows residential densities between 15 and 24 dwelling units per acre. The Project also includes a Zone Change to change the site zoning from C-TR to R3 (Multiple-Family Residential) with application of the Small Lot Subdivision Development Standards for fee simple duplex and detached residences.
2.2 Project Trip Generation
The trip generation for the proposed Project was analyzed in accordance with the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition (2021). ITE Trip Generation Manual, 1976
2375 North Tustin Street Project VMT Analysis
5 12th Edition (2025) has been released at the time of this analysis. However, substantial progress on the Project was made before the ITE 12th Edition rates came out. Additionally, the trip generation rates from ITE 11th Edition represent a more conservative analysis. Therefore, trip generation rates from ITE 11th Edition are utilized for this analysis.
For the existing land use, ITE Land Use Code 863 (Electronics Superstore) was applied to represent the Best Buy store. Although no trip credit was applied for the existing use in this analysis, it was included to illustrate the number of trips previously generated by the site when the Best Buy was operational.
Table 1 presents the trip generation for the Best Buy store. As shown in Table 1, the Best Buy store was estimated to generate 1,875 daily trips, 16 AM peak hour trips, and 194 PM peak hour trips.
The proposed 71 dwelling units were analyzed using ITE Land Use Code 215, Single-Family Attached Housing. Table 2 presents the trip generation for the proposed Project. As shown in Table 2, the proposed Project is expected to generate a total of 511 daily trips, including 34 AM peak hour and 40 PM peak hour trips.

7 3 VMT BACKGROUND AND SIGNIFICANCE
THRESHOLD
Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the California Environmental Quality Act (CEQA) Guidelines to replace level of service (LOS) as the appropriate method for evaluating transportation impacts under CEQA. SB 743 specified that the new criteria should promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses. The bill also specified that delay-based LOS could no longer be considered an indicator of a significant impact on the environment under CEQA. In response, the Natural Resources Agency amended the CEQA Guidelines to include Section 15064.3, Determining the Significance of Transportation Impacts. This section states that VMT is the most appropriate measure of a project’s transportation impacts and provides lead agencies with the discretion to choose the most appropriate methodology and thresholds for evaluating VMT. Section 15064.3(c) states that the provisions of the section shall apply statewide beginning on July 1, 2020.
3.1 City of Orange VMT Screening Criteria
The City’s Guidelines provide the following screening criteria to identify if a project would be considered to have a less-than-significant impact on VMT and therefore could be screened out from further VMT analysis:
1. Transit Priority Area (TPA) Screening.4 Projects located within a TPA may be presumed to have a less-than-significant impact on VMT.
2. Low VMT Area Screening. Projects located within a low VMT-generating area and consistent with the existing land uses within that traffic analysis zone (TAZ) may be presumed to have a less-thansignificant impact on VMT.
3. Project Type Screening. Projects that propose local-serving land use may be presumed to have a less-than-significant impact on VMT.
4 A TPA is defined as a half-mile area around an existing major transit stop or an existing stop along a highquality transit corridor per the definitions below.
Pub. Resources Code, § 21064.3 - ‘Major transit stop’ means a site containing an existing rail transit station, a ferry terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods.
Pub. Resources Code, § 21155 - For purposes of this section, a ‘high-quality transit corridor’ means a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.
Assembly Bill 2553 changed the definition of “major transit stop” from a 15-minute to 20-minute bus route service interval.
1979
2375 North Tustin Street Project VMT Analysis
8 If a project meets one of the criteria above, then the VMT impact of the Project would be considered less-than-significant and no further analysis of VMT would be required.
3.2 VMT Significance Threshold
Projects that do not meet any screening criteria should complete VMT analysis and forecasting through the Orange County Transportation Analysis Model (OCTAM) to determine if they have a significant VMT impact. This analysis should include both ‘project-generated VMT’ for the project TAZ (or TAZs) and ‘project effect on VMT’ estimates. VMT thresholds provided below are to be applied to determine potential project-generated VMT impacts and project’s effect on VMT impacts.
A project would result in a significant project-generated VMT impact if either of the following conditions are satisfied:
• The baseline project-generated VMT per service population exceeds the City of Orange General Plan Buildout VMT per service population; or
• The cumulative project-generated VMT per service population exceeds the City of Orange General Plan Buildout VMT per service population
The project’s effect on VMT would be considered significant if it resulted in either of the following conditions being satisfied:
• The baseline link-level boundary Citywide VMT per service population increases under the plus project condition compared to the no project condition; or • The cumulative link-level boundary Citywide VMT per service population increases under the plus project condition compared to the no project condition.
Please note that the cumulative “no project” shall reflect the adopted Regional Transportation plan/Sustainable Communities Strategy (RTP/SCS); as such, if a project is consistent with the Southern California Association of Governments (SCAG) RTP/SCS (Connect SoCal), then the cumulative impacts (project effect on VMT) shall be considered less than significant subject to consideration of other substantial evidence.
1980
2375 North Tustin Street Project VMT Analysis
9 4 VMT ANALYSIS
4.1 VMT Screening Analysis
The applicability of each screening criteria to the Project is discussed below.
Screening Criteria 1 – Transit Priority Area (TPA) Screening Projects located within a TPA may be presumed to have a less-than-significant impact on VMT absent substantial evidence to the contrary. This presumption may NOT be appropriate if the project:
1. Has an 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 Sustainable Communities Strategy (as determined by the lead agency, with input from the Southern California Association of Governments [SCAG]); or
4. Replaces affordable residential units with a smaller number of moderate- or high-income residential units.
Based on the “NOCC+ (North Orange County Collaborative)” tool provided by the City of Orange that was last updated in 2021, the Project site located at 2375 North Tustin Street in the City of Orange is not located within a TPA. However, the NOCC+ user guide also instructs the analyst to confirm transit service at the time of analysis. Thus, current transit services were reviewed to confirm if the Project is located within a TPA.
Public transportation is provided to the City by the Orange County Transportation Authority (OCTA).
There are several existing bus routes along N. Tustin Avenue, including Routes 42, 46, 50, 71, and 167.
The closest OCTA bus stop is located across from the Project site on N. Tustin Avenue. As shown in the transit information provided in Appendix B, OCTA improved the frequency of Route 50 along N. Tustin Avenue to 15 minutes during peak hours, which became effective in November 2025. Therefore, the Project is located within a TPA under the most up-to-date transit service frequency.
However, the Project does not satisfy all other required TPA screening criteria:
• Floor Area Ratio (FAR): As previously described in Section 2.1, the Project has a proposed FAR of
0.79, exceeding the 0.75 minimum requirement.
• Parking: The City of Orange requires a total of 174 parking stalls for the Project. o The Project provides a total of 179 parking stalls, which is 5 more parking stalls than the amount required by the City. Therefore, the Project does not meet this screening criteria. • SCS Consistency: The Project is consistent with the SCS as listed below:
o The Project would develop 71 townhome residences, which would generate between 178 and 224 residents. According to the California Department of Finance, the City had a population of 139,724 in 2025 with 48,301 housing units. The increase in 71 housing units would equate to a
0.15 percent increase in housing units within the City and the increase of 224 residents would equate to a 0.16 percent increase in population. Compared to growth projections, the proposed 1981
2375 North Tustin Street Project VMT Analysis
10 71 residences equates to 3.3 percent of the SCAG projected increase in households in the City between 2024 and 2050.
o The City’s 2021-2029 Housing Element Update details that the City has a Regional Housing Needs Allocation (RHNA) of 3,936 units. Of the RHNA units, 677 (17.1%) would be for moderate income households and 1,588 units (40.4%) would be for above moderate income households.
The proposed 71 residences equates to 1.8 percent of the City’s total RHNA allocation, and 3.1 percent of the City’s moderate and above moderate income household RHNA allocations.
Overall, the Project's generation of housing is consistent with growth projections in the SCS. o In addition, vehicle trips included in the SCS is based on the Project site’s existing General Plan land use designation of General Commercial (GC) that allows a maximum Floor Area Ratio (FAR) of 1.0 and emissions generated by the existing 45,676 square foot retail store building that was constructed in 2007. The former Best Buy store generated approximately 1,875 daily vehicle trips and the proposed 71 residential units under the proposed Project would generate approximately 511 daily vehicle trips. Thus, the proposed Project would not result in growth in vehicle trips or related emissions and would not conflict with the SCS. • Affordable Housing Displacement: The Project site does not include existing residential units and does not result in the displacement of any affordable housing.
Therefore, while the Project is in a TPA, it does not meet all the requirements for Screening Criteria 1.
The Project would not meet Screening Criteria 1 because it includes 5 more parking stalls than the amount required by the City.
Screening Criteria 2 – Low VMT Area Screening
The City’s Guidelines utilize the “NOCC+” tool to identify low VMT-generating areas for screening purposes. Under these guidelines, projects located within areas that generate VMT below the City of Orange General Plan Buildout VMT per service population (hereafter referred to as VMT/SP) may be presumed to have a less-than-significant VMT impact and may be screened from detailed VMT analysis.
However, the land use assumptions within the NOCC+ tool and screening maps available for this site are inconsistent with the proposed Project, as the historical use of the site was not residential.
Additionally, a preliminary review of the OCTAM model shows the project is not located in a low VMT area. Therefore the Project would not meet Screening Criteria 2.
Screening Criteria 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:
• Local-serving K-12 schools
• Local parks
• Day care centers
• Local-serving retail uses less than 50,000 square feet, including:
o Gas stations
o Banks
1982
2375 North Tustin Street Project VMT Analysis
11 o Restaurants
o Shopping Center
• Local-serving hotels (e.g. non-destination hotels)
• Student housing projects on or adjacent to a college campus • Local-serving assembly uses (places of worship, community organizations) • Community institutions (public libraries, fire stations, local government) • Affordable, supportive, or transitional housing
• Assisted living facilities
• Senior housing (as defined by HUD)
• Local serving community colleges that are consistent with the assumptions noted in the RTP/SCS • Projects generating less than 110 daily vehicle trips o This generally corresponds to the following “typical” development potentials:
11 single family housing units
16 multi-family, condominiums, or townhouse housing units 10,000 SF of office
15,000 SF of light industrial
63,000 SF of warehousing
79,000 SF of high cube transload and short-term storage warehouse As previously analyzed in Section 2.2, the proposed residential Project (71 dwelling units) is expected to generate a total of 511 daily trips, including 34 AM peak hour trips and 40 PM peak hour trips. As the Project is neither a local-serving use, as defined by the City, nor does it generate fewer than 110 average daily trips, it does not meet Screening Criteria 3 for project type screening.
The Project would not meet any of the City’s screening criteria; therefore, a full analysis of VMT was prepared for the Project.

2375 North Tustin Street Project VMT Analysis
12 4.2 OCTAM Model Configuration
The City’s Guidelines require the use of OCTAM, which incorporates the most recent roadway circulation and land use data from the City’s current General Plan, for preparation of VMT analyses. OCTAM includes validated scenarios for the model’s Base Year (2019) and Cumulative Year (2050).
The Project is located within TAZ 573. Prior to conducting the VMT model runs, the OCTAM roadway network near the Project site was reviewed, and no changes were necessary for the roadway network.
The VMT for Base and Cumulative Year With Project conditions was derived under the following steps:
• The original land use from the Project TAZ 573 was moved to an adjacent TAZ, TAZ 572. • The Project land use was then added to the isolated TAZ 573, where the Project is located, so that the Project-generated VMT can be identified:
o 71 DUs were added to TAZ 573.
o The total population and employed population for the Project was calculated based on the existing household occupancy of TAZ 573:
The existing TAZ 573 contains 337 DUs and 1126 residents, which equates to an average household occupancy of 3.34 residents/DU.
Similarly, TAZ 573 contains 337 DUs and 833 employed residents, which equates to an average rate of 2.47 employed residents/DU.
o Using the existing rates, a population of 237 residents and an employed population of 175 residents were added to TAZ 573.
All OCTAM VMT inputs can be found in Appendix C. With the land use inputs noted above, OCTAM was run for the Base Year (2019) and Cumulative Year (2050) under No-Project and With-Project conditions (i.e., four full Model runs).
The total Origin-Destination (OD) VMT of the Project TAZ was evaluated using the OCTAM VMT postprocessor from the OCTAM Base Year (2019) and Cumulative Year (2050) With-Project Model runs. To determine OD VMT/Service Population (VMT/SP), the total OD VMT of the Project TAZ is divided by the total Service Population (Service Population = Population + Employment + Enrollment) of the Project TAZ. The 2025 VMT/SP of the Project TAZ was interpolated using linear interpolation between the 2019 and 2050 Model outputs.
All OCTAM VMT outputs can be found in Appendix C.
1984
2375 North Tustin Street Project VMT Analysis
13 4.3 Project-Generated VMT Evaluation
The applicable threshold for the City of Orange is based on the City of Orange General Plan Buildout VMT per service population. The City’s VMT/SP threshold of 31.3 VMT/SP under Cumulative Year (2050) was obtained using the NOCC+ Tool.
The baseline VMT for the Project TAZ (TAZ 573) was determined using the OCTAM VMT post-processor results using linear interpolation between the 2019 and 2050 With-Project model outputs.
Due to the increased density of residential units proposed by the Project, Measure T-1: Increase Residential Density from the California Air Pollution Control Officers Association (CAPCOA) Handbook for Analyzing Greenhouse Gas (GHG) Emission Reductions, Assessing Climate Vulnerabilities, and Advancing Health and Equity (October 2024) was utilized to adjust the baseline VMT results to more accurately analyze the Project.
The proposed Project would develop 71 residential units on a 4.235-acre site. As defined by CAPCOA Measure T-1, “An acre in this context is defined as an acre of developed land, not including streets, school sites, parks, and other undevelopable land.” As shown in Figure 1: Project Site Plan, the net acreage of the site, which excludes Lot #A, #B and #C totaling 1.09 acres from the 4.235-acre site, would be 3.145 acres. The net density of the Project is calculated to be 22.57 units per net acre, and provides a reduction in VMT pursuant to CAPCOA Measure T-1, as detailed below:
• T-1 CAPCOA Measure T-1: Increase Residential Density. This measure accounts for the VMT reduction achieved by a project that has a higher density of dwelling units (DU) compared to the average residential density. Increased densities have been shown to affect the distance people travel and may result in greater options for the mode of travel they choose. Increasing residential density can result in shorter and fewer trips by single-occupancy vehicles. The residential density of the Project is calculated by dividing the total number of dwelling units (71 DUs) by the net acreage (3.145 acres) of the Project. Based on this, the residential density is calculated to be 22.57 units per net acre. The equation for the reduction in VMT is based on the residential density of the Project and the residential density of a typical development, or the residential density in the relevant TAZ5. o Using the residential density of TAZ 573 where the Project is located under existing conditions of 13.27 DU/ac (338 households6 in the 26.9 residential acres [25.47 net acres]7 within TAZ 573) as shown in Figure 2: Density Calculation for Existing Residential Units within TAZ 573, the Project-generated VMT would be reduced by 15.4%.
The supporting documentation and calculation for the VMT reduction can be found in Appendix D. 5 Per the CAPCOA Handbook, Increase Residential Density (T1), p. 71, the formula for VMT reduction is A = ((B - C) / C) × D, where A (0–30.0%) represents the percentage reduction in GHG emissions from project VMT in the study area, B (du/acre) is the residential density of the project development (dwelling units per acre), C is the residential density of a typical development (9.1 du/acre); however, the residential density of the relevant Transportation Analysis Zone (TAZ) should be used instead of this typical value, and D (-0.22) is the elasticity of VMT with respect to residential density. 6 Number of households in TAZ 573 is provided by City of Orange. 7 Acreage is calculated using ArcGIS Pro.

14 The Project’s VMT analysis results, applying the 15.4% reduction of total VMT, for the Project (TAZ 573) using OCTAM are shown in Table 3, OCTAM VMT Analysis of Project – TAZ 573. As shown in Table 3, the Project’s VMT/SP would be 11.7% below the threshold under Project Baseline (2025) Conditions and 7.1% below the threshold under Cumulative (2050) Conditions. Therefore, the proposed Project would result in a less-than-significant Project-generated VMT impact.

16 4.4 Project’s Effect on VMT
According to the City’s Guidelines, if a project causes the link-level boundary Citywide VMT per service population within the City to be higher than the No Project scenario under baseline or cumulative conditions, the project’s effect on VMT would be considered significant.
A boundary method analysis was conducted to evaluate the Project’s cumulative effect on VMT. The daily VMT within the City is calculated by the sum of total link-based VMT of all the roadways within the City. The roadways selected to calculate daily VMT are shown below in Figure 3.
Figure 3: Roadways Selected to Calculate Daily VMT
To calculate the daily VMT/SP, the total daily VMT within the City is divided by the total service population of the City. The total service population within the City is calculated by the sum of total population and employees of all the TAZs within the City.
The Project’s effect on VMT results are shown in Table 4. The citywide No Project VMT/SP for the City of Orange is 14.117 for Base Year (2019) and 14.514 for Cumulative Year (2050). Therefore, the City’s threshold of significance for Project Baseline (2025) was interpolated to be 14.197 VMT/SP.
As shown in Table 4, the Orange Citywide Boundary VMT/SP is 0.02% lower with the Project added under Project Baseline (2025) Conditions and 0.03% lower with the Project added under Cumulative (2050) Conditions. Therefore, the Project’s effect on VMT would be less than significant. 1988

2375 North Tustin Street Project VMT Analysis
18 5 VMT CONCLUSION
This VMT Analysis has been prepared to analyze the potential transportation related impacts of the proposed 2375 North Tustin Street Project.
The City or Orange’s Guidelines provide the following screening criteria to identify if a project would be considered to have a less-than-significant impact on VMT and therefore could be screened out from further VMT analysis:
1. Is the Project within one-half mile of qualifying transit?
2. Is the Project in a low VMT area?
3. Is the Project a local serving land use?
The Project would not meet all of the City’s screening criteria; therefore, a full analysis of VMT was prepared for the Project.
The proposed Project would result in a residential density of 22.57 units per net acre, which has a higher density than typical residential projects and provides for a reduction in VMT pursuant to Measure T-1:
Increase Residential Density from the CAPCOA Handbook. Therefore, the proposed Project VMT/SP would is on the following calculation:
• T-1 CAPCOA Measure T-1: Increase Residential Density. This measure accounts for the VMT reduction achieved by a project that has a higher density of dwelling units (DU) compared to the average residential density. Increased densities have been shown to affect the distance people travel and may result in greater options for the mode of travel they choose. Increasing residential density can result in shorter and fewer trips by single-occupancy vehicles.
The residential density of the Project is calculated by dividing the total number of dwelling units (71 DUs) by the net acreage (3.145 acres) of the Project. Based on this, the residential density is calculated to be 22.57 units per net acre. The equation for the reduction in VMT is based on the residential density of the Project and the residential density of a typical development, or the residential density in the relevant TAZ8.
o Using the residential density of TAZ 573 where the Project is located under existing conditions of 13.27 DU/ac (338 households in the 26.9 residential acres [25.47 net acres] within TAZ 573), the Project-generated VMT would be reduced by 15.4%.
The Project’s VMT analysis results, applying the 15.4% reduction of total VMT, would be 11.7% below the threshold under Project Baseline (2025) Conditions and 7.1% below the threshold under Cumulative 8 Per the CAPCOA Handbook, Increase Residential Density (T1), p. 71, the formula for VMT reduction is A = ((B - C) / C) × D, where A (0–30.0%) represents the percentage reduction in GHG emissions from project VMT in the study area, B (du/acre) is the residential density of the project development (dwelling units per acre), C is the residential density of a typical development (9.1 du/acre); however, the residential density of the relevant Transportation Analysis Zone (TAZ) should be used instead of this typical value, and D (-0.22) is the elasticity of VMT with respect to residential density.

19 (2050) Conditions. Therefore, the proposed Project would result in a less-than-significant Projectgenerated VMT impact.
The Orange Citywide Boundary VMT/SP is 0.02% lower with the Project added under Project Baseline (2025) Conditions and 0.03% lower with the Project added under Cumulative (2050) Conditions.
Therefore, the Project’s effect on VMT would be less than significant. 1991

Prepared by: Simon Lin, EIT, Alex J. Garber, EPD Solutions Inc To: Maria Flores, City of Orange Public Works – Traffic Division Site: 2375 North Tustin Street, Orange (APN: 372-642-31) Subject: Vehicle Miles Traveled Scope of Work for North Tustin Street Residential Project In response to comments received on the draft VMT analysis prepared for this Project, this memo outlines the proposed scope of work for the Vehicle Miles Traveled (VMT) analysis for the proposed residential development located at 2375 North Tustin Street (APN: 372-642-31) (Project), in the City of Orange. The Project description and proposed scope of work are discussed in detail below.
Project Name: North Tustin Street Residential Project
Project Address: 2375 North Tustin Street, Orange, CA, 92865 Project Description: The existing site area is 4.235 gross acres and is fully developed with a vacant 45,676 square foot (SF) Best Buy retail store building, surface parking lot, and landscaping. The existing onsite improvements were constructed in 2007 and were operational through October 2023. The entire site is relatively flat and is accessible via the existing driveway to North Tustin Avenue. The proposed Project will demolish the existing structure and improvements on the Project site and then develop 71 paired and detached residences, open space/recreation, and parking. The residential structures would be three-stories in height and range in size from approximately 2,008 square foot three-bedroom units to 2,117 square foot four-bedroom units that would be developed above two-car garages for each of the units. The 71 residences on the 4.235-acre site would result in a density of 16.76 units per acre. The Project site plan is shown in Figure 1.
Trip Generation and VMT Screening: The Trip Generation and VMT Screening Analysis of the Project was evaluated in North Tustin Street Residential VMT Screening Memo submitted to City of Orange dated September 29, 2025. Upon the City of Orange’s review of the memo, the LOS analysis was accepted and a full VMT analysis was requested.
Vehicle Miles Traveled Analysis:
The Project will conduct a VMT analysis using the Orange County Transportation Analysis Model (OCTAM).
The following tasks will be undertaken to prepare the VMT analysis:
1. In order to evaluate base year (2019) and the future year (2050) with-Project conditions, EPD will modify the OCTAM model by updating the Project’s socio-economic data (SED) to input Project data into the existing TAZ 573, where the Project is located. The original land use in TAZ 573 is moved to the adjacent TAZ (TAZ 572), in order to isolate TAZ 573 so that the Project-generated VMT can be identified.
1994
North Tustin Street Residential Project
Vehicle Miles Traveled Analysis Scope of Work
2 Four full model runs will be conducted to evaluate VMT for both the base year (2019) and the future year (2050), under both with-Project and without Project conditions. The proposed Model Land Use Inputs for the proposed Project is provided in Attachment A.
2. The model output will be post-processed to calculate the total daily VMT/Service Population (SP) for analysis year 2025, which will be interpolated from the base year (2019) and buildout year (2050) model runs. Project VMT impacts will be determined using the significance criteria outlined in the City's guidelines.
3. The Project’s effect on VMT will be evaluated by calculating the Citywide link-level VMT per Service Population for without and with Project conditions. The Project is considered to have a significant impact if the link level VMT per Service Population is increased under with Project conditions.
4. If a significant VMT impact is identified, EPD will identify appropriate mitigation measures such as change in the Project description, transportation demand management (TDM) measures, or participation in an impact fee and/or exchange program (if any applicable to the Project) to reduce VMT to achieve acceptable levels.
We appreciate your review of this information. Upon completion of your review, please forward any comments or approval of this methodology to [email protected]. If you have any questions, please do not hesitate to contact us by e-mail or on (949) 794-1180.

Co-Benefits (icon key on pg. 34)
Climate Resilience
Increased density can put people closer to
resources they may need to access during
an extreme weather event. Increased density
can also shorten commutes, decreasing the
amount of time people are on the road and
exposed to hazards such as extreme heat
or flooding.
Health and Equity Considerations
Neighborhoods should include different
types of housing to support a variety of
household sizes, age ranges, and incomes.
Measure Description
This measure accounts for the VMT reduction achieved by a project that is designed with a higher density of dwelling units (du) compared to the average residential density in the U.S. Increased densities affect the distance people travel and provide greater options for the mode of travel they choose. Increasing residential density results in shorter and fewer trips by single-occupancy vehicles and thus a reduction in GHG emissions. This measure is best quantified when applied to larger developments and developments where the density is somewhat similar to the surrounding area due to the underlying research being founded in data from the
neighborhood level.
Subsector
Land Use
Locational Context
Urban, suburban
Scale of Application
Project/Site
Implementation Requirements
This measure is most accurately quantified when applied to larger developments and/or developments where the density is
somewhat similar to the surrounding neighborhood.
Cost Considerations
Depending on the location, increasing residential density may increase housing and development costs. However, the costs of providing public services, such as health care, education, policing, and transit, are generally lower in more dense areas where things are closer together. Infrastructure that provides drinking water and electricity also operates more efficiently when the service and transmission area is reduced. Local governments may provide approval streamlining benefits or financial incentives for infill and high-density residential projects.
Expanded Mitigation Options
When paired with Measure T-2, Increase Job Density, the cumulative densification from these measures can result in a highly walkable and bikeable area, yielding increased co-benefits in VMT reductions, improved public health, and social equity. 30%

Further explanation of key variables:
▪ (C) – The residential density of typical development is based on the blended average density of residential development in the U.S. forecasted for 2025. This estimate includes apartments, condominiums, and townhouses, as well as detached single-family housing on both small and large lots. An acre in this context is defined as an acre of developed land, not including streets, school sites, parks, and other undevelopable land. If reductions are being calculated from a specific baseline derived from a travel demand forecasting model, the residential density of the relevant transportation analysis zone should be used instead of the value for a typical development.
▪ (D) – A meta-regression analysis of five studies that controlled for self-selection found that a 0.22 percent decrease in VMT occurs for every 1 percent increase in residential density (Stevens 2016).
GHG Calculation Caps or Maximums
Measure Maximum
(Amax) The percent reduction in GHG emissions (A) is capped at 30 percent. The purpose for the 30 percent cap is to limit the influence of any single built environmental factor (such as density). Projects that implement multiple land use strategies (e.g., density, design, diversity) will show more of a reduction than relying on improvements from a single built environment factor.
2015
T-1. Increase Residential Density TRANSPORTATION | 72
Subsector Maximum
( ∑ AmaxT-1 through T-4 ≤65%) This measure is in the Land Use subsector. This subcategory includes Measures T-1 through T-4. The VMT reduction from the combined implementation of all measures within this subsector is capped at 65 percent.
Example GHG Reduction Quantification
The user reduces VMT by increasing the residential density of the project study area. In this example, the project’s residential density would be 15 du per acre (B), which would reduce GHG emissions from project VMT by 14.2 percent.
Quantified Co-Benefits
Improved Local Air Quality
The percent reduction in GHG emissions (A) would be the same as the percent reduction in NOX, CO, NO2, SO2, and PM. Reductions in ROG emissions can be calculated by multiplying the percent reduction in GHG emissions (A) by an adjustment factor of 87 percent. See Adjusting VMT Reductions to Emission Reductions above for further discussion.
Energy and Fuel Savings
The percent reduction in vehicle fuel consumption would be the same as the percent reduction in GHG emissions (A).
VMT Reductions
The percent reduction in VMT would be the same as the percent reduction in GHG emissions (A).

CITY OF ORANGE NORTH TUSTIN STREET RESIDENTIAL PROJECT
INITIAL STUDY/MITIGATED NEGATIVE DECLARATION
NO. ENV25-0001
Mitigation Monitoring and Reporting Plan
The California Environmental Quality Act (CEQA) requires that when a public agency completes an environmental document which includes measures to mitigate or avoid significant environmental effects, the public agency must adopt a reporting or monitoring plan. This requirement ensures that environmental impacts found to be potentially significant will be mitigated. The reporting or monitoring plan must be designed to ensure compliance during project implementation (Public Resources Code Section 21081.6).
In compliance with Public Resources Code Section 21081.6, the attached Mitigation Monitoring and Reporting Checklist, has been prepared for the North Tustin Street Residential Project. The table identifies Project Design Features (PDFs); Plans, Programs, and Policies (PPPs); and Mitigation Measures (MMs) required by the City to mitigate or avoid significant adverse impacts associated with the implementation of the Project. This Mitigation Monitoring and Reporting Checklist is intended to provide verification that all applicable mitigation measures relative to significant environmental impacts are monitored and reported. Monitoring will include: 1) verification that each mitigation measure has been implemented; 2) recordation of the actions taken to implement each mitigation measure; and 3) retention of records in the City’s North Tustin Street Residential project file.
This Mitigation Monitoring and Reporting Program (MMRP) delineates responsibilities for monitoring the Project but also allows the City flexibility and discretion in determining how best to monitor implementation. Monitoring procedures will vary according to the type of mitigation measure. Adequate monitoring consists of demonstrating that monitoring procedures took place and that mitigation measures were implemented. This includes the review of all monitoring reports, enforcement actions, and document disposition, unless otherwise noted in the Mitigation Monitoring and Reporting Checklist. If an adopted mitigation measure is not being properly implemented, the designated monitoring personnel shall require corrective actions to ensure adequate implementation.
Reporting consists of establishing a record that a mitigation measure is being implemented, and generally involves the following steps:
• The City distributes reporting forms to the appropriate entities for verification of compliance.
• Departments/agencies with reporting responsibilities will review the Mitigated Negative Declaration, which provides general background information on the reasons for including specified mitigation measures.
• Periodic meetings may be held during Project implementation to report on compliance of mitigation measures.
• Responsible parties provide the City with verification that monitoring has been conducted and ensure, as applicable, that mitigation measures have been implemented. Monitoring 2018
City of Orange North Tustin Street Residential Project
Mitigation Monitoring and Reporting Program MND NO. ENV25-0001 2 compliance may be documented through existing review and approval programs such as field inspection reports and plan review.
• The City prepares a reporting form periodically during the construction phase and an annual report summarizing all project mitigation monitoring efforts. • Appropriate mitigation measures will be included in construction documents and/or conditions of permits/approvals.
Minor changes to the MMRP, if required, would be made in accordance with CEQA and would be permitted after review and approval by the City. Such changes could include reassignment of monitoring and reporting responsibilities, plan redesign to make any appropriate improvements, and/or modification, substitution or deletion of mitigation measures subject to conditions described in CEQA Guidelines Section 15162. No change will be permitted unless the MMRP continues to satisfy the requirements of Public Resources Code Section 21081. 2019

5. PROJECT DESCRIPTION
The project involves a request to demolish a vacant retail store (former Best Buy) and develop 71 three-story single-family small lot homes (58 paired and 13 detached), open space recreation area, guest parking, and related site improvements (See Attachment 8 Project Plans).
To allow for the development in this location, the applicant is proposing a General Plan Amendment to change the General Plan Land Use Element designation from General Commercial Max. 1.0 FAR (GC) to Medium Density Residential 15-24 dwelling units per acre (MDR), and a Zone Change from Limited Business Tustin Redevelopment Project Area (C-TR) to Residential Multiple Family (R-3) to accommodate a small lot subdivision in accordance with the City’s Small Lot Subdivision Ordinance (OMC Section 17.14.270). The proposed development will have a density of 16.76 dwelling units per acre. The proposal includes a Vesting Tentative Tract Map for the small lot subdivision including establishment of private and common use areas.
The Small Lot Subdivision Development Standards and Guidelines allow for the development of smaller fee simple, single-family residential lots in multi-family residential zones (R-3, R-4) and the Neighborhood Mixed Use (NMU-24) zone. The lots created under these standards are less than the typical minimum area of a traditional single-family lot, which allows for flexibility in lot configuration, City of Orange Page 3 of 10 Printed on 4/2/2026
powered by Legistar™2068
Item #: 3.1. 4/6/2026 File #: 26-0167
typical minimum area of a traditional single-family lot, which allows for flexibility in lot configuration, and reduces the amount of land required for new-single family residences. The development standards include regulations for lot frontage, setbacks, stories, height, private open space, and parking. These development standards allow for a space-efficient and economical alternative to traditional options for home ownership.
The project includes small lots ranging from 1,515 to 3,376 square feet. There are 36 units located within the interior cluster that have primary entries off landscaped paseos and walkways, and 35 units along the northern, southern, and western boundaries that have primary entries off the looped roadway and interior walkways.
The project provides five different floor plans with units ranging from 2,008 to 2,117 square feet (See Sheet SP - Site Plan of Attachment 8). In addition, each unit plan provides garage space dedicated for the storage of three trash carts for the collection of solid waste, recyclables, and organics and a minimum of 120 cubic feet of storage.

Architecture
The project site is located within an area containing a mix of commercial and residential uses with eclectic architectural styles. The project introduces a contemporary residential design that is intended to respond to the visual character of the area. All units feature three-stories. Units within the interior cluster incorporate roof decks with a maximum building height of 35 feet. No roof decks are proposed on units along the perimeter boundaries, adjacent to existing single-story condominiums and mobile homes to the north and south. The building orientations along the property boundaries consider the site’s characteristics and the City’s Small Lot Subdivision Guidelines (Attachment 11) in that the main entrances are oriented towards the private roadway and walkways to create a relationship between the buildings and pedestrians and to establish a strong tie to the internal street frontages. The main entrances of the units within the interior cluster are oriented towards the landscaped paseos or walkways. These paseos/walkways connect to the private roadways, open space recreation area, and public right-of-way.
Architectural elements of the proposed residences include a combination of flat, gable, and shed roof forms, parapets, arched and rectangular entries, recessed and simple door and window detailing, City of Orange Page 4 of 10 Printed on 4/2/2026
powered by Legistar™2069
Item #: 3.1. 4/6/2026 File #: 26-0167
forms, parapets, arched and rectangular entries, recessed and simple door and window detailing, porch elements, use of trim and siding, and alternating plane changes to add visual interest. The use of varied rooflines, articulated building elevations, and arches help soften the scale and rectangular massing of the buildings and are generally compatible with the architecture of the commercial buildings to the west. The proposed exterior building materials include composite roof shingles, painted stucco finish, metal canopies, vinyl windows, stucco over foam trim details, engineered wood siding, metal balcony railing, and painted metal sectional garage doors. The coordinated exterior color scheme consists of subtle natural tones, with contrasting colors used for accents and details.
Project Access and Parking:
Vehicle access to the project site is provided by an existing signalized shared two-way driveway entrance along Tustin Street. This entry drive connects to a looped private interior roadway and two additional interior roadways off the interior cluster that provide vehicle and pedestrian access to the main entrances and garages of the dwelling units. There is an emergency vehicle access gate that leads to an emergency access easement dedicated to the City of Orange located at the northeast corner of the site and on the adjacent property to the north. The internal roadways include curb, gutter, and intermittent landscape planters. Each unit is provided with an attached two-car garage with 14 unenclosed on-lot parking spaces dedicated for four bedroom units, and 23 unenclosed guest parking spaces, for a total of 179 parking spaces provided for the development. The project provides 5 spaces in excess of the 174 parking spaces required by the Small Lot Subidivison Ordinance. Also, one additional dedicated postal service parking space is provided at the entrance to the common open space area.
Pedestrian access from Tustin Street is provided via an existing paved sidewalk/walkway along the south side of the entrance driveway that connects to a network of interior walkways that lead to unit entries and common open space amenities. The project is also within walking distance to nearby shopping, restaurants, office, and residential uses, as well as adjacent to multiple bus stops located on the east and west sides of Tustin Street in the general vicinity of the project site. The private interior roadways, open parking spaces, common open space, and landscape areas designated on Sheet HM (HOA Maintenance Exhibit) of Attachment 8 will be maintained by a Homeowner’s Association for the development.
Common and Private Open Space:
The Small Lot Subdivision development standards require a project to provide common open space only if the buildings on each lot exceed 75% lot coverage. As noted on Sheet SP (Site Plan) of Attachment 8, lot coverage for the project ranges from 25 to 55.7% and therefore the project is not required to provide common open space. However, in an effort to enhance the project aesthetics and provide amenities to the residents, the applicant has provided a common open space area with shaded picnic tables, multipurpose lawn area, mailboxes, and bicycle parking across from the main entrance to the development. The project also provides private open space in the form of roof decks for all units in the interior cluster, and 10-foot rear yards for units along the northern, southwestern, and southern boundaries.
Landscaping
Sheet L-7 (Schematic Existing Tree Plan) of Attachment 8 shows the removal of 68 existing mature trees in order to accommodate the new residential development. A total of 12 existing Palm trees and landscaping will be protected in place along both sides of the shared main entrance driveway.

Item #: 3.1. 4/6/2026 File #: 26-0167
Sheets L-4 - L-5B (Schematic Planting Plan and Plant Images) of Attachment 8 illustrates the proposed water efficient landscape palette for the project. The project incorporates 126 new trees, including Date Palms, Jacaranda, Southern Magnolia, Crape Myrtle, and Marina Strawberry trees, with a mix of shrubs and groundcover, including Big Red Kangaroo Paw, Spanish Lavender, Blue Gem Coast Rosemary, and artifical turf in the common open space area. Private roadway treatment includes the incorporation of Sweet Bay columnar trees between the paired units and similar shrubs and groundcover in the intermittent landscape planters. The landscaping proposed along the interior walkways and paseos provides a friendly pedestrian-oriented interface with the buildings. Enhanced paving is proposed at the main entrance to the development, and in the common open space seating area. Interior walkways will be concrete and four feet wide.
Fences/Walls
Sheet L-3 (Schematic Wall and Fence Plan) of Attachment 8 illustrates existing walls to remain in place along the northern, southern, and southwestern boundaries of the site. A new 8-foot wall with a sliding metal access gate (8 feet tall x 20 feet wide for existing billboard maintenance purposes) is proposed along the eastern boundary, new 6-foot side yard walls with vinyl gates are proposed between units along the perimeter boundaries, and a new 3-foot wall is proposed on the west side of the common open space turf area. No side yard fencing/walls are proposed between units within the interior cluster of homes.
Lighting
Sheets L-9A - L-9B of Attachment 8 include the Photometric Plan and fixture designs for the project.
New 15-foot-tall LED pole streetlights are proposed in landscape planters at the project entry, in front of the common open space area, looped roadway, and adjacent to unenclosed resident and guest parking spaces. These fixtures will have shields directed downward to prevent off-site light spillage.
Various landscape lighting, including shade structure down lighting, in-ground flush mounted fixtures, tree and sign up-lighting will also be provided. Decorative LED wall light fixtures (shown on building elevations) are proposed at the front, rear, and side elevations of the residences within the center cluster, and on the front and side elevations on the perimeter boundaries. The proposed fixture styles are contemporary and compatible with the architecture of the buildings.
Signage
Conceptual signage is included for illustrative purposes on Sheet L-3 of Attachment 8 and is not part of this project proposal. A new 6-foot stucco entry pilaster with development identification signage is proposed on the north side of the project entry. The sign concept appears compatible with the building design; however, the City’s Building Security Ordinance will likely require a lighted address on the sign and at each residential unit. All signage will comply with the City’s sign regulations.
Overall, the project’s coordinated architectural style, use of matching colors and materials for all structures, as well as landscape design as proposed presents an integrated design theme. The project provides a residential design that is distinctive, yet compatible with the commercial and neighborhood area context.
6. PROJECT ANALYSIS
The project as proposed complies with the OMC and the City’s Small Lot Subdivision Development Standards and Guidelines (See Table on Sheet SL of Attachment 8).
The project site has been vacant for two years with no viable lease or commercial development City of Orange Page 6 of 10 Printed on 4/2/2026
powered by Legistar™2071
Item #: 3.1. 4/6/2026 File #: 26-0167
The project site has been vacant for two years with no viable lease or commercial development options despite continuous efforts by the property owner. In order to support redevelopment of the property with the proposed residential project as opposed to the continuance of commercial uses at the site, the applicant has submitted a Fiscal Impact Analysis by Stanley R. Hoffman Associates, Inc. (Attachment 6), which demonstrates a positive economic impact to the City including an annual recurring net contribution to the City’s general fund and one-time development impact fees. The study also indicates that “the project will have a stabilizing effect on the neighborhood through community ties and economic development benefits from new household spending on goods and services captured within the City”.
Land Use
The proposed General Plan Amendment and Zone Change are necessary to allow for residential development on this site. The presence of residential uses along this portion of Tustin Street is logical given the already existing residential development to the north and south of the site, as well as the neighborhood-serving goods and services in the area. The MDR General Plan designation and R-3 zoning are consistent with the General Plan and zoning designations of the existing abutting residential land use to the north (Park 72 Condominiums, 1800 E. Heim Avenue) and the abutting R3 zoning (Coco Palms Condominiums, 2295 N. Tustin Street) to the south, and generally compatible with commercial land uses that would remain to the west, which accommodates a mix of retail and service commercial uses and professional offices. The land use changes also enable the implementation of the Small Lot Subdivision Development Standards, which allows for alternative infill housing typologies within multiple-family residential zones.
The proposed small lot development is also consistent with the intent of the MDR land use designation and R-3 zoning, in that the project provides private and common open space with amenities, a pedestrian-friendly integration along Tustin Street, is adjacent to public transportation, and is in close proximity to commercial, retail, medical and professional offices, and recreational uses.
Project Design
Because of the project’s flag lot configuration, the three-story residential units will be set back more than 220 feet from the Tustin Street right-of-way and partially buffered by existing one-story commercial buildings along the street frontage (Orange Village Dentistry at 2393 N. Tustin Street and new bank building under construction at 2355 N. Tustin Street). Residential developments to the north and south are similarly located and buffered by commercial development. This substantial setback directs the project’s three-story massing away from the Tustin Street right-of-way containing primarily one-story commercial buildings, and does not visually affect the existing appearance of the Tustin Street corridor.
The project’s site configuration includes three-story units backing the northern and southern boundaries, abutting one-story condominium and mobile home developments. During initial review of the project, Staff raised concerns to the applicant regarding the potential for shading/shadowing and the loss of privacy for the abutting neighbors. In response, the applicant has provided Shade/Shadow Exhibits and Line of Sight Section details on Sheets A18-19 and A22 of Attachment 8.
Shade and Shadow
City of Orange Page 7 of 10 Printed on 4/2/2026

Item #: 3.1. 4/6/2026 File #: 26-0167
Shading/shadowing is a potential impact when a building(s) blocks sunlight from neighboring properties. The CEQA guidelines have not established shade/shadow thresholds of significance, nor has the City of Orange formally adopted thresholds as part of the City’s local CEQA Guidelines; however, the City considers project impacts to be significant if a substantial amount of sensitive uses/areas would be shaded by project related features for three continuous hours or more on any given day during the winter and summer solstice or spring and fall equinox. The residential buildings are considered shadow sensitive areas to account for solar panels and windows providing light into a residence.
The Shade/Shadow Exhibits illustrate existing and proposed effects during the winter solstice (December 21), when the sun is at the lowest point in the sky resulting in the most restrictive time period, and the summer solstice (June 21), when the sun is at its highest point in the sky. It appears that shading/shadowing with project conditions would not affect the abutting multifamily residential properties for more than three hours during the winter and summer solstice from 9:00 a.m. to 3:00 p.m. Shading/shadowing appears to affect only adjacent property drive aisles, unenclosed parking, and enclosed garages, rather than individual living areas.
The Shade/Shadow Exhibits also illustrate that the majority of the project site will be shaded during the winter solstice from 9 a.m. to 3:00 p.m. While the shading would not affect adjacent property uses, Staff encouranged the use of sun sensitive landscaping for sustainability reasons on the project site.
Line of Sight
The proposed three-story units are located approximately 10 feet from the north and south property lines, and between 61 feet, 10 inches to 64 feet away from the single-story condominium living units.
Because the adjacent condominium living units are separated by drive aisles, open and enclosed parking, it appears that there will be no privacy impacts created by the second and third story windows of the new homes as illustrated in Sections A, B and D.
Section C illustrates the proximity of the new three-story homes to the nearest mobile home living area with windows, located at the southeast corner of the site. It appears that there is a 21-foot separation between the units and that there is existing landscaping/tree on the mobile home property that serves as a visual screen from the second and third story windows of the new units, therefore maintaining the privacy of the mobile homeowner.
While the introduction of infill residential development into an existing urban setting comes with complexities related to site planning and community interface, staff believes that the change in General Plan and zoning designations from commercial to residential will have a positive economic impact to the City supported by the applicant’s Fiscal Impact Analysis, and will not visually impact the Tustin Street corridor given the large setback distance from the Tustin Street right-of-way. The architectural design, exterior materials, and landscaping presents a unifying theme and results in an internally consistent design that is compatible with the eclectic mix of styles in the surrounding area.
Further, this residential development project implements the Small Lot Subdivision Development Standards and supports the City’s Regional Housing Needs Allocation (RHNA) by adding units to the overall housing inventory on a site that had not previously been identified as a Candidate Housing Site in the Housing Element.

7. AUTHORIZING GUIDELINES
Orange Municipal Code (OMC) Table 17.08.020 depicts the authority of the City’s reviewing bodies to make decisions and/or recommendations on land use applications. This project involves applications for a General Plan Amendment, Zone Change, Tentative Tract Map, Major Site Plan Review, Administrative Design Review, and Environmental Review which require a final determination by the City Council. Table 17.08.020(b) states that when more than one type of application is filed for a single project, the application requiring the highest level of approval shall dictate the review process for the entire group of applications. Therefore, the Planning Commission is to act in an advisory capacity to the City Council for the sum of applications for the project because the City Council is the final decision-maker for the General Plan and zoning change.
8. PUBLIC NOTICE
Notice was provided to property owners, tenants, and persons specifically requesting notice and posted at the site on or before March 12, 2026. The notice was also published in the Anaheim Bulletin newspaper on March 12, 2026.
9. ENVIRONMENTAL REVIEW
Click or tap here to enter text.
Mitigated Negative Declaration: Mitigated Negative Declaration (MND) No. ENV25-0001 (SCH No. 2026020142) was prepared to evaluate the physical environmental impacts of the project, in conformance with the provisions of the California Environmental Quality Act (CEQA) per State CEQA Guidelines Section 15070 and in conformance with local CEQA guidelines. The analysis contained in MND No. ENV25-0001 determined that the project will have less than significant impacts to the environment with the implementation of Project Design Features, Plans, Programs, and Policies, relating to Aesthetics, Air Quality, Cultural Resources, Energy, Geology and Soils, Greenhouse Gas Emissions, Hydrology and Water Quality, Noise, and Tribal Cultural Resources, and Mitigation Measures relating to Biological Resources, Noise, and Tribal Cultural Resources.
The Mitigation Monitoring and Reporting Program of the Final MND summarizes the Project Design Features, Plans, Programs and Policies, Mitigation Measures, and the responsible party for the implementation and monitoring (Attachments 9 and 10). On February 5, 2026, a Notice of Intent (NOI) to Adopt Mitigated Negative Declaration No. ENV25-0001 was filed with the Orange County Clerk Recorder, posted at the site, mailed to property owners and tenants within a 300-foot radius of the project site, potentially affected cities, public agencies, utility service providers, and published in the Anaheim Bulletin newspaper on February 5, 2026. The public review period began on February 5, 2026, and ended on February 25, 2026. The MND was made publicly available at the Community Development Department, City Clerk’s office, and the City’s website.
Public comments on MND No. ENV25-0001 were received from the California Department of Transportation (Caltrans), Pala Band of Mission Indians, and six community members. Caltrans recognizes that the pattern of land use can affect both local vehicle miles traveled and number of trips, and supports local developments that promote equity, strengthen the economy, protect the environment, and provide a diversity of housing choices accessible to transportation facilities, promote the design of Complete Streets with high-quality pedestrian, bicycle, and transit facilities, describes the project adjacency to bike lanes, supports inclusion of secure and functional short term bike parking and provides guidance on bicycle parking best practices, indicates that work within Caltrans right-of-way will require discretionary approval, and requests coordination with Caltrans on City of Orange Page 9 of 10 Printed on 4/2/2026
