11 CONSTRUCTION IMPACTS
This section analyzes potential impacts resulting from the short‐term construction activities associated with the development of the Project. Exhibit ͭͭ‐ͭ shows the on‐site construction noise source activity, including the off‐site roadway and utility improvements in relation to the nearest sensitive receiver locations previously described in Section ʹ. As part of the construction noise analysis, the preexisting Ͳ‐ to ʹ‐foot‐high barrier along the southern site boundary was modeled.

The City of Orange has set restrictions to control noise impacts associated with the construction of the proposed Project. Section ʹ.ͮͰ.ͱͬ of the City’s Municipal Code states: Noise sources associated with construction, repair, remodeling, or grading of any real property, provided said activities take place between the hours of ͳ:ͬͬ a.m. and ʹ:ͬͬ p.m. on any day except for Sunday or a Federal holiday, or between the hours of ͵:ͬͬ a.m. and ʹ:ͬͬ p.m. on Sunday or a Federal holiday. (ͭͳ)

11.1 CONSTRUCTION NOISE LEVELS
The FTA Transit Noise and Vibration Impact Assessment Manual recognizes that construction projects are accomplished in several different stages and outlines the procedures for assessing noise impacts during construction. Each stage has a specific equipment mix, depending on the work to be completed during that stage. As a result of the equipment mix, each stage has its own noise characteristics; some stages have higher continuous noise levels than others, and some have higher impact noise levels than others. The Project construction activities are expected to occur in the following stages:
• Demolition
• Site Preparation
• Grading
• Building Construction
• Paving
• Architectural Coating

11.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe construction noise activities, this construction noise analysis was prepared using reference construction equipment noise levels from the Federal Highway Administration (FHWA), which published the Roadway Construction Noise Model (RCNM), which includes a national database of construction equipment reference noise emission levels. (ͯͭ) The RCNM equipment database provides a comprehensive list of the noise‐generating characteristics of specific types of construction equipment. In addition, the database provides an acoustical usage factor to estimate the fraction of time each piece of construction equipment is operating at full power (i.e., its loudest condition) during a construction operation. According to the EPA, FTA, and FHWA, the overall construction noise level is governed primarily by the noisiest pieces of equipment. The quieter pieces do not affect the overall level, but they do reduce the magnitude of the fluctuations in the noise level.

Therefore, a rough estimate of the noise level need only include the noisiest pieces of equipment expected at the site. (ͯͮ) (͵) (ͯͯ) Consistent with FHWA and FTA guidance for detailed construction ͭͲͰͯʹ‐ͬͱ NA Ͳͬ North Tustin Street Project
noise assessment, Table ͭͭ‐ͭ presents the combined noise levels for the loudest construction activities expected for each stage, assuming all equipment operates simultaneously.

3 Sound power level represents the total amount of acoustical energy (noise level) produced by a sound source independent of distance or surroundings.

11.3 CONSTRUCTION NOISE ANALYSIS
Construction projects involve various stages, and activities frequently shift from one location to another. For example, during site preparation and grading, noise‐generating activities may concentrate in an area for a short period to remove an obstruction, while the majority of the grading involves the equipment moving back and forth in a predictable pattern throughout the site; building construction and foundation work generally concentrate near the building footprint, while paving generally involves a predictable pattern of movement throughout the site. Therefore, construction activities are best evaluated as multiple moving point sources within the construction area since the speed and power of the equipment vary and the equipment constantly changes position in terms of distance and direction relative to the receivers. (͵) (ͯͰ) Using the reference construction equipment noise levels and the CadnaA noise prediction model, calculations of the Project construction noise level impacts by phase at the nearby sensitive receiver locations were completed. To account for the dynamic nature of construction activities, the CadnaA construction noise analysis evaluates the noise source activities as multiple moving point sources, or construction crews, within the limits of construction. Construction impacts are based on the loudest activity and the highest noise level ͭͲͰͯʹ‐ͬͱ NA Ͳͮ North Tustin Street Project
calculated at each receiver location. As shown in Table ͭͭ‐ͮ, the construction noise levels are expected to range from Ͳͳ.ͱ to ͳͱ.ͮ dBA Leq at the nearby receiver locations. Appendix ͭͭ.ͭ includes the detailed CadnaA construction noise model inputs.

CadnaA construction noise model inputs are included in Appendix 11.1.

11.4 PROJECT SITE CONSTRUCTION NOISE LEVEL COMPLIANCE
To evaluate whether the Project will generate potentially significant short‐term noise levels at the nearest receiver locations, a construction‐related daytime noise level threshold of ʹͬ dBA Leq is used as a reasonable threshold to assess the daytime construction noise level impacts. The construction noise analysis shows that the nearest receiver locations will satisfy the reasonable daytime ʹͬ dBA Leq significance threshold during Project construction activities, as shown in Table ͭͭ‐ͯ. Therefore, the noise impacts due to Project construction noise are considered less than significant at all receiver locations.

3 Construction noise level thresholds as shown in Table 4-1. 4 Do the estimated Project construction noise levels exceed the construction noise level threshold?

11.5 TEMPORARY CONSTRUCTION NOISE LEVEL INCREASES
To describe the temporary Project construction noise level contributions to the existing ambient noise environment, the Project construction noise levels were combined with the existing ambient noise levels measurements at the nearest off‐site receiver locations. The difference between the ͭͲͰͯʹ‐ͬͱ NA Ͳͯ North Tustin Street Project
combined Project‐construction and ambient noise levels is used to describe the construction noise level contributions. Temporary noise level increases that would be experienced at sensitive receiver locations when the Project construction‐source noise is added to the ambient daytime conditions are presented in Table ͭͭ‐Ͱ. A temporary noise level increase of ͮͬ dBA is considered a potentially significant impact based on the Caltrans substantial noise level increase criteria, which is used to assess the Project‐construction noise level increases. (ͯͱ) As indicated in Table ͭͭ‐Ͱ, the Project will contribute to construction noise increases ranging from ͱ.ͱ to ͭͳ.ͭ dBA Leq during the daytime hours at the nearest receiver locations. The unmitigated construction noise analysis shows that the nearest receiver locations will not exceed the ͮͬ dBA Leq substantial noise level increase significance threshold during Project construction activities. The temporary construction noise level increase analysis shows that the noise impacts due to the Project construction noise are considered less than significant.

11.6 CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods employed. The operation of construction equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Ground vibration levels associated with various types of construction equipment are summarized in Table ͭͬ‐Ͳ. Based on the representative vibration levels presented for various construction equipment types, it is possible to estimate the potential for human response (annoyance) and building damage using the following vibration assessment methods defined by Caltrans. To describe the vibration impacts, Caltrans provides the following equation: PPV (in/sec)equip = PPV (in/sec)ref x (ͮͱ/D)ͭ.ͭ ͭͲͰͯʹ‐ͬͱ NA ͲͰ North Tustin Street Project

Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual Using the vibration source level of construction equipment provided in Table ͭͭ‐ͱ and the construction vibration assessment methodology published by the FTA and Caltrans, it is possible to estimate the Project vibration impacts. Table ͭͭ‐Ͳ presents the expected Project‐related vibration levels at the nearby receiver locations. At distances ranging from ͱ to ͮͯͲ feet from Project construction activities, construction vibration velocity levels are estimated to range from ͬ.ͬͭ to ͮ.ͯͱ PPV (in/sec). Based on the maximum acceptable vibration threshold of ͬ.ͯͬ PPV (in/sec), the typical Project construction vibration levels will exceed the vibration thresholds at sensitive uses represented by receiver Rͯ. Therefore, the Project‐related vibration impacts are considered significant during typical construction activities at the Project site and will require mitigation.

It should be noted that vibration levels at the site of the closest sensitive receiver are unlikely to be sustained during the entire construction period, but will occur only during the times that heavy construction equipment is operating adjacent to the Project site perimeter. Moreover, construction at the Project site will be restricted to the daytime hours, consistent with City of Orange requirements, eliminating potential vibration impacts during the sensitive evening and nighttime hours.

11.7 CONSTRUCTION VIBRATION IMPACTS MITIGATION
A ͮͬ‐foot equipment buffer zone is required to restrict the use of heavy construction equipment (greater than ʹͬ,ͬͬͬ pounds), vibratory rollers, large loaded trucks, and large bulldozers within ͮͬ feet of sensitive receivers. With the mitigation measure identified in this analysis and shown in Exhibit ES‐ͭ, and as demonstrated in Table ͭͭ‐ͳ, the mitigated vibration levels with the ͮͬ‐foot equipment buffer zone will be reduced to ͬ.ͮ͵ PPV (in/sec) and will satisfy the ͬ.ͯͬ PPV (in/sec) threshold. Therefore, with the construction vibration mitigation measure identified in this study, vibration impacts will be less than significant.

NOI‐ͭ Vibratory rollers, large loaded trucks, and dozers (equipment weighing ʹͬ,ͬͬͬ pounds or more) shall not be allowed within ͮͬ feet of any off‐site receiver location at the time of Project construction. Instead, smaller, rubber‐tired bulldozers (less than ʹͬ,ͬͬͬ pounds) shall be used within this area during Project construction to reduce vibration levels.

11.8 CONCRETE CRUSHING NOISE AND VIBRATION
Concrete crushing would be used during demolition to breakdown building material. There are various phases in concrete crushing, also known as stations. These various stages exist because passing material through one stage alone may not be enough to crush the rock down to a desired shape and size.

It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, tertiary, and quaternary stations are installed to reduce the rock to the desired size, shape, and ͭͲͰͯʹ‐ͬͱ NA ͲͲ North Tustin Street Project
consistency. Unlike typical construction activity, the concrete crushing activity is assessed using the stationary source construction noise level limit.

11.8.1 Concrete Crushing Construction Reference Noise Levels This analysis was completed to assess potential noise level impacts due to concrete crushing activities. Exhibit ͭͭ‐ͮ shows the anticipated location of the crushing activity area in relation to the nearest receiver locations. Table ͭͭ‐ʹ provides a summary of the reference average Leq noise levels used to describe concrete crushing construction activities. The reference noise level summary describes construction activity noise levels with multiple pieces of construction equipment operating simultaneously, and includes source noise levels for a hoe‐ram or pavement breaker, which is a percussion hammer fitted to an excavator for breaking rock, and a concrete crushing activity including an impact hammer (hoe ram), front‐end loader, and dump truck.

11.8.2 Concrete Crushing Construction Noise Analysis and Compliance Using the reference crushing construction equipment noise levels, calculations of the Project construction noise level impacts at the nearest sensitive receiver locations were completed. To assess the worst‐case construction noise levels, the Project construction noise analysis relies on the highest noise level impacts when multiple pieces of equipment with the highest reference noise level are operating at the closest point from the edge of primary construction activity (as shown on Exhibit ͭͭ‐ͮ) to each receiver location.

The concrete crushing construction noise levels are estimated to range from Ͳͯ.ͬ to ͳͯ.ͮ dBA Leq at the nearest receiver locations. The Concrete crushing construction noise analysis shows that the nearest receiver locations will satisfy the reasonable daytime ʹͬ dBA Leq significance threshold.

Therefore, the noise impacts due to the Project Concrete crushing noise are considered less than significant at all receiver locations.

11.8.3 Concrete Crushing Construction Vibration Analysis and Compliance Using the vibration source level of the construction equipment list provided in Table ͭͭ‐ͱ, which includes source levels for a hoe ram or breaker representing a percussion hammer fitted to an excavator for breaking rock. Table ͭͭ‐͵ presents the expected concrete crushing construction equipment vibration levels when the equipment with the highest reference vibration activity is operating at the closest point from the edge of the concrete crushing activity to each receiver location.

At distances ranging from ͭʹͳ to ͱͲͯ feet from the concrete crushing activities, as shown on Exhibit ͭͭ‐ͮ, construction vibration levels are estimated to be less than ͬ.ͬͭ PPV (in/sec) and will remain below the City of Orange ͬ.ͯͬ PPV (in/sec) threshold for vibration at all receiver locations. Therefore, the Project‐related vibration impacts are considered less than significant during the Project concrete crushing construction activities at the Project site.

Editor's note— Ord. No. 1-14, § I, adopted August 12, 2014, repealed the former Ch. 8.24, §§

8.24.010—8.24.110 and enacted a new Ch. 8.24 as set out herein. The former Ch. 8.24 pertained to similar subject matter and derived from Prior Code 9500.1—9500.16; Ord. Nos. 49-74, 17-74, 1-80, and 26-96.

8.24.010 - Policy.

A. In order to control unnecessary, excessive and annoying sounds emanating from the City, it is the policy of the City to regulate such sounds generated from all sources as specified in this chapter.

The intent of this chapter is to protect residential land uses from unnecessary, excessive and annoying sounds.

B. It is determined that certain sound levels are detrimental to the public health, welfare and safety, and contrary to public interest.
(Ord. No. 1-14, § I, 8-12-14)

8.24.020 - Definitions.

The following words, phrases and terms as used in this chapter shall have the meaning as indicated below:

A. "Ambient noise level" means the all-encompassing noise level associated with a given environment, being a composite of sounds from all sources, excluding the alleged offensive noise, at the location and approximate time at which a comparison with the alleged offensive noise is to be made.

B. "Adjusted ambient noise level" means the measured ambient noise level plus 3 dB (A). Three (3) dB (A) is the industry-accepted threshold of human perceptibility for a change in the noise environment.

C. "Decibel (dB)" means a unit which denotes the ratio between two quantities which are proportional to power: the number of decibels corresponding to the ratio of two amounts of power is ten times the logarithm to the base ten of this ratio.

D. "Emergency machinery, vehicle or work" means any machinery, vehicle or work used, employed or performed in an effort to protect, provide or restore safe conditions in the community or for the citizenry, or work by private or public utilities when restoring utility service.

E. "Fixed noise source" means a stationary noise source which creates sounds while fixed or motionless, including but not limited to construction equipment, industrial and commercial machinery and equipment, pumps, fans, compressors, generators, air conditioners and refrigeration equipment.

F. "Grading" means any excavating or filling of earth material or any combination thereof conducted to prepare a site for construction or other improvements thereon.

G. "Hourly Average" (L eq ) means the energy mean or average sound level over a one (1) hour period of time.

H. "Impact noise" means the noise produced by the collision of one mass in motion with a second mass which may be either in motion or at rest.
74 I. "Mobile noise source" means any noise source other than a fixed noise source.

J. "Noise level" means the "A" weighted sound pressure level in decibels obtained by using a sound level meter at slow response with a reference pressure of twenty (20) micronewtons per square meter. The unit of measurement shall be designated as dB(A).

K. "Person" means a person, firm, association, co-partnership, joint venture, corporation or any entity, public or private in nature.

L. "Recurring impulsive noise" means a noise of short duration, usually less than one (1) second, with an abrupt onset and rapid decay, which occurs repeatedly or in a cyclical manner.

Any noise level measurements made pursuant to the provisions of this chapter shall be performed using a sound level meter as defined in Section 8.24.020P. (Ord. No. 1-14, § I, 8-12-14)

8.24.040 - Exterior Standards.

A. The following noise standards for fixed noise sources, unless otherwise specifically indicated, shall apply to all residential property:

Table 8.24.040 Exterior Noise Standards
Noise Level Time Period
Hourly Average (L eq ) 55 dB (A) 7:00 a.m.—10:00 p.m.
50 dB (A) 10:00 p.m.—7:00 a.m.

Maximum Level 70 dB (A) 7:00 a.m.—10:00 p.m.
65 dB (A) 10:00 p.m.—7:00 a.m.
75 B. It is unlawful for any person at any location within the City to create any noise, or to allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level when measured on any other residential property to exceed the noise standards identified in Table 8.24.040. For multi-family residential or mixed use developments located within the City's Urban Mixed Use, Neighborhood Mixed Use, Old Towne Mixed Use or Medium Density Residential General Plan land use districts, exterior noise standards shall apply to common recreation areas only and shall not apply to private exterior space (such as a private yard, patio, or balcony).

C. In the event the ambient noise level exceeds the noise standards identified in Table 8.24.040 of this section, the "adjusted ambient noise level" shall be applied as the noise standard. In cases where the noise standard is adjusted due to a high ambient noise level, the noise standard shall not exceed the "adjusted ambient noise level", or 70 dB (A), whichever is less. In cases where the ambient noise level is already greater than 70 dB (A), the ambient noise level shall be applied as the noise standard.

D. Each of the noise limits specified in Table 8.24.040 shall be reduced by 5 dB(A) for impact or simple tone noises, recurring impulsive noises, or for noises consisting of speech or music. (Ord. No. 1-14, § I, 8-12-14)

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
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

North Tustin Street Residential Project
LOS Analysis Screening Memo
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.

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 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. 2375 North Tustin Street Project VMT Analysis
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, 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.
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.

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 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
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.
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.
2375 North Tustin Street Project VMT Analysis
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. 2375 North Tustin Street Project VMT Analysis

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.
2375 North Tustin Street Project VMT Analysis
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. 2375 North Tustin Street Project VMT Analysis

Subject: RE: 2375 N. Tustin Street - VMT Comments (GPA2025-0003 et al) Hi Monique,
Attached is the VMT scoping agreement that was submitted to the traffic division. I only have one comment, for #2 the applicant shall also evaluate project generated VMT/SP in the future year 2050 condition. The attached document also has the same comment.

The applicant does not need to resubmit the scoping agreement, they can continue with the VMT analysis as long as they also evaluate project generated VMT/SP in the future year 2050 condition.

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.

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.
