Relevant Policy Project Consistency Analysis
Goal CON-2 Protect and enhance native trees and vegetation throughout the city Policy CON 2-3 Avoid removal of large, mature
trees that provide wildlife habitat, visual
screening, or contribute to the visual quality of
the environment through appropriate project
design and building siting. If full avoidance is not
possible, prioritize planting of replacement trees
on-site over off-site locations. Replacement trees
for high-quality mature trees should generally be
of like kind, and provide for comparable habitat
functionality, where appropriate site conditions
exist.
Consistent. Although the Project would remove 35 trees onsite, the Project would plant 6 new trees and preserve 58 trees on-site to maintain the overall visual quality of the Project Site to the same level as the site’s existing conditions.
Goal CON-7 Implement a proactive approach to maintain and improve air quality within Milpitas and the region
Policy CON 7-2 Minimize exposure of the public
to toxic or harmful air emissions and odors
through requiring an adequate buffer or setback
distance between residential and other sensitive
land uses and land uses that typically generate
air pollutants, toxic air contaminants, or
obnoxious fumes or odors, including but not
limited to industrial, manufacturing, and
processing facilities, high-volume roadways, and
industrial rail lines. New sensitive receptors,
such as residences (including residential care and
assisted living facilities for the elderly), childcare
centers, schools, playgrounds, churches, and
medical facilities shall be located away from
existing point sources of air pollution such that
excessive levels of exposure do not result in
unacceptable health risks. Compliance shall be
verified through the preparation of a Health Risk
Assessment when deemed necessary by the
Planning Director.
Consistent. As discussed in Section 2, Air Quality, the Project would not exceed the Bay Area Air Quality Management
District construction and operational thresholds for emissions of the region’s identified criteria pollutants (i.e., ROG, NOx, CO, SO2, PM10 and PM2.5). Section 2 of this IS/MND also concluded that the Project would not have the potential to expose sensitive receptors to substantial pollutant
concentrations, as students are only on-campus during school hours and because diesel exhaust emissions would be low and short term. Furthermore, due to the Project Site’s distance to stationary sources of TAC emissions, the Project would not contribute to human health risk to nearby receptors during operation, and the Project would also not contribute to any cumulative human health risk impact

City of Milpitas Zoning
The Project Site is currently zoned by the City as General Commercial (C2). Under Section XI-10-5.02 (Commercial Use Regulations) of the City’s Municipal Code, private schools (elementary, middle, high) would be considered as an acceptable use under C2 zoning, provided that a Conditional Use Permit (CUP) is issued to the Project Applicant prior to Project approval. Prior to issuance of the CUP, the Project site plan and supporting documents would be reviewed and considered by the City as part of the Project Application submitted by the Project Applicant. As stated in XI-10-5.04 (Commercial Zone Special Development Standards) of the City’s Municipal Code, the Planning Commission shall consider site conditions and design elements of the Project prior to the issuance of a CUP. The Project would renovate the existing office building and would not alter the current size, height, massing, and setback of the existing building. The new building under the Project (i.e., gymnasium) would be inconsistent with two

development standards outlined in Table XI-10-5.03-1, Commercial Zone General Development Standards, of the City’s Municipal Code as it would not meet the Floor Area Ratio and building height requirements.
To address areas of nonconformity, the Project will include a Development Agreement. The Development Agreement is a legally binding contract between the Project Applicant and the City that outlines the terms and conditions for the Project. This approach will ensure that any deviations from the MMSP or the Zoning Code are appropriately mitigated and managed, providing a mechanism for the City to ensure compliance with its planning objectives while accommodating the needs of the Project. Approval of the Development Agreement will be adopted as an ordinance by the City Council, as part of the Project approval process..
Upon approval and issuance of the CUP and the Development Agreement, the Project would be consistent with the City’s Municipal Code.
In conclusion, the Project would be generally consistent with the relevant policies and standards under the MMSP, City’s General Plan and Municipal Code for development in BPRD-R and C2 zones.
Therefore, the Project would not conflict with any local land use plan, policy, or regulation, and impacts would be less than significant.
Mitigation Measures: No mitigation measures are required.

Characteristics of Noise
Noise is usually defined as unwanted sound that is an undesirable byproduct of society’s normal day-today activities. Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm, and/or when it has adverse effects on health. Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). The human ear does not respond uniformly to sounds at all frequencies. For example, the human ear is less sensitive to low and high frequencies than medium frequencies, which more closely correspond with human speech. In response to the sensitivity of the human ear to different frequencies, the A-weighted noise level (or scale), which corresponds better with people’s subjective judgment of sound levels, has been developed. This A-weighted sound level, referenced in units of dBA, is measured on a logarithmic scale such that a doubling of sound energy results in a 3 dBA increase in noise level. Typically, changes in a community noise level of less than 3 dBA are not noticed by the human ear.
41 Changes from 3 to 5 dBA may be noticed by some individuals who are sensitive to changes in noise. A greater than 5 dBA increase is readily noticeable, while the human ear perceives a 10 dBA increase in sound level to be a doubling of sound.

On the A-weighted scale, the range of human hearing extends from approximately 3 to 140 dBA. Table
3.13-1, A-Weighted Decibel Scale, provides examples of A-weighted noise levels from common sources.
Noise sources occur in two forms: (1) point sources, such as stationary equipment or individual motor vehicles; and (2) line sources, such as a roadway with a large number of point sources (motor vehicles).
Sound generated by a point source typically diminishes (attenuates) at a rate of 6 dBA for each doubling of distance from the source to the receptor at acoustically “hard” sites and 7.5 dBA at acoustically “soft” sites.42,43 For example, if a noise source produces a noise level of 89 dBA at a reference distance of 50 feet, the noise level would be 83 dBA at a distance of 100 feet from the noise source, 77 dBA at a distance of 200 feet, and so on. Noise generated by a mobile source will decrease by approximately 3 dBA over hard surfaces and 4.5 dBA over soft surfaces for each doubling of distance.44 Table 3.13-1

Sound levels also can be attenuated by man-made or natural barriers (e.g., sound walls, berms, and ridges), as well as elevational differences. Noise is most audible when traveling by direct line-of-sight, an uninterrupted visual path between the noise source and noise receptor. Barriers, such as walls or buildings that break the line-of-sight between the source and the receiver, can greatly reduce noise levels from the 42 Federal Highway Administration, Highway Traffic Noise: Analysis and Abatement Guidance, 2011.

43 Examples of “hard” or reflective sites include asphalt, concrete, and hard and sparsely vegetated soils. Examples of acoustically “soft” or absorptive sites include soft, sand, plowed farmland, grass, crops, heavy ground cover, etc.

source since sound can only reach the receiver by diffraction. However, if a barrier is not high or long enough to break the line-of-sight from the source to the receiver, its effectiveness is greatly reduced.
Equivalent Noise Level
Equivalent Noise Level (Leq) is the sound level corresponding to a steady-state A-weighted sound level containing the same total energy as several single event noise exposure level events during a given sample period. Leq is the “acoustic energy” average noise level during the period of the sample. It is based on the observation that the potential for noise annoyance is dependent on the total acoustical energy content of the noise. The equivalent noise level is expressed in units of dBA. Leq can be measured for any period, but is typically measured for 15 minutes, 1 hour, or 24 hours. Leq for a 1-hour period is used by the Federal Highway Administration (FHWA) for assessing highway noise impacts. Leq for 1 hour is referred to as the Hourly Noise Level (HNL) in the California Airport Noise Regulations and is used to develop Community Noise Equivalent Level values for aircraft operations. Construction noise levels and ambient noise measurements in this section use the Leq scale.
Characteristics of Vibration
Vibration consists of waves transmitted through solid material. Groundborne vibration propagates from a source through the ground to adjacent buildings by surface waves. Vibration may comprise a single pulse, a series of pulses, or a continuous oscillatory motion. The frequency of a vibrating object describes how rapidly it is oscillating and is measured in hertz (Hz). Most environmental vibrations consist of a composite, or “spectrum” of many frequencies, and are generally classified as broadband or random vibrations. The normal frequency range of most groundborne vibration that can be felt generally starts from a low frequency of less than one Hz to a high of about 200 Hz. Vibration is often measured in terms of the peak particle velocity (PPV) in inches per second (in/sec) when considering impacts on buildings or other structures, as PPV represents the maximum instantaneous peak of vibration that can stress buildings.
Because it is a representation of acute vibration, PPV is often used to measure the temporary impacts of short-term construction activities that could instantaneously damage existing structures. Vibration is often also measured by the Root Mean Squared (RMS) because it best correlates with human perception and response. Specifically, RMS represents “smoothed” vibration levels over an extended period of time and is often used to gauge the long-term chronic impact of a project’s operation on the adjacent environment.
RMS amplitude is the average of a signal’s squared amplitude. It is most commonly measured in decibel notation (VdB).
Vibration energy attenuates as it travels through the ground, causing the vibration amplitude to decrease with distance away from the source. High frequency vibrations reduce much more rapidly than low
3.0 Environmental Checklist
Impact Sciences, Inc. 3.0-76 Stratford Preparatory School Project 1451.002 May 2024
frequencies, so that in the far-field from a source, the low frequencies tend to dominate. Soil properties also affect the propagation of vibration. When groundborne vibration interacts with a building, there is usually a ground-to-foundation coupling loss (i.e., the foundation of the structure does not move in sync with the ground vibration), but the vibration can also be amplified by the structural resonances of the walls and floors. Vibration in buildings is typically perceived as rattling of windows or items on shelves, or the motion of building surfaces. At high levels, vibration can result in damage to structures.
Manmade groundborne vibration is generally limited to areas within a few hundred feet of certain types of construction activities, especially pile driving. Road vehicles rarely create enough groundborne vibration to be perceptible to humans unless the road surface is poorly maintained and there are potholes or bumps.
If traffic induces perceptible vibration in buildings, such as window rattling or shaking of small loose items (typically caused by heavy trucks in passing), then it is most likely an effect of low-frequency airborne noise or ground characteristics.
Regulatory Framework
Federal Transit Administration Vibration Guidance
The Federal Transit Administration (FTA) has published guidance relative to vibration impacts.
Construction vibration damage criteria are assessed based on structural category (e.g., reinforced-concrete, steel, or timber). The FTA guidelines consider 0.2 inch/sec PPV to be the significant impact level for nonengineered timber and masonry buildings. Structures or buildings constructed of reinforced concrete, steel, or timber have a vibration damage criterion of 0.5 inch/sec PPV pursuant to FTA guidelines.45 The FTA guidelines include a table showing the vibration damage criteria based on structural category and is presented below in Table 3.13-2, Construction Vibration Damage Criteria. 45 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018.

Local Plans and Policies
City of Milpitas 2040 General Plan
The Noise Element of the General Plan contains goals, policies, and actions that seek to reduce community exposure to excessive noise levels through the establishment of noise level standards for a variety of land uses.46 The Noise Element includes information on existing and projected noise conditions with policies and programs to maintain or reduce noise from transportation, land use operations and single-event noise.
Applicable Goals, Policies and Actions include:
Goal N-1: Preserve a nuisance-free noise environment for existing and future land uses by minimizing exposure to harmful and excessive noise levels.
Policy N 1-1: Consider the noise compatibility of existing and future development when making land use planning decisions. Require development and infrastructure projects to be consistent with the land use compatibility standards contained in Tables N-1 and N-2 to ensure acceptable noise exposure levels for existing and future development.
Policy N 1-2: Require new development to mitigate excessive noise to the standards indicated in Tables N-1 and N-2 through best practices, including building location and orientation, building design features, placement of noisegenerating equipment away from sensitive receptors, shielding of noise46 City of Milpitas, General Plan 2040, adopted March 9, 2021.

generating equipment, placement of noise-tolerant features between noise sources and sensitive receptors, and use of noise-minimizing materials.
Policy N 1-3: Use sound walls for sound attenuation only when other measures are not practical, or when recommended by an acoustical expert as part of a mitigation measure. Sound walls shall be designed to be aesthetically pleasing, and should incorporate features such as vegetation, variations in color and texture, artwork, and other features deemed appropriate by the City.
Policy N 1-5: Require acoustical studies for new discretionary developments and transportation improvements that have the potential to affect existing noise-sensitive uses such as schools, hospitals, libraries, care facilities, and residential areas; and for projects that would introduce new noisesensitive uses into an area where existing noise levels may exceed the thresholds identified in this element.
Policy N 1-6: For projects that are required to prepare an acoustical study to analyze noise impacts, the following criteria shall be used to determine the significance of those impacts:
Stationary and Non-Transportation Noise Sources
A significant impact will occur if the project results in an exceedance of the noise level standards contained in this element. In instances where the ambient noise level is already above the standards contained in this element, a significant impact will occur if the project will result in an increase in ambient noise levels by more than 3 dB. This does not apply to temporary construction activities.
Transportation Noise Sources
Where existing traffic noise levels are 60 dB Ldn or less at the outdoor activity areas of noise-sensitive uses, a +5 dB Ldn increase in roadway noise levels will be considered significant;
3.0 Environmental Checklist
Impact Sciences, Inc. 3.0-79 Stratford Preparatory School Project 1451.002 May 2024
Where existing traffic noise levels are greater than 60 dB Ldn and up to 65 dB Ldn at the outdoor activity areas of noise-sensitive uses, a +3 dB Ldn increase in roadway noise levels will be considered significant; and Where existing traffic noise levels are greater than 65 dB Ldn at the outdoor activity areas of noise-sensitive uses, a +1.5 dB Ldn increase in roadway noise levels will be considered significant.
Applicable Actions in Support of Goal N-1
Action N-1a: Require that new development projects are reviewed for compliance with the noise requirements established in this element, including the standards established in Tables N-1 and N-2, prior to project approval.
Action N-1b: Require acoustical studies for new development projects which have the potential to generate noise impacts which exceed the standards identified in this element. The studies shall include representative noise measurements, estimates of existing and projected noise levels, and mitigation measures necessary to ensure compliance with the noise standards included in this element. Studies shall be conducted by a qualified acoustical professional.
Action N-1c: Require developers to prepare a construction management/noise mitigation plan that defines best management practices to reduce construction noise, and includes proposed truck routes (that comply with Section 12 V-100-12.05 - Truck Routes of the Milpitas Municipal Code) as part of the entitlement process.
Action N-1d: During the environmental review process, determine if proposed construction will constitute a significant impact on nearby sensitive receptors and, if necessary, require mitigation measures in addition to the standard best practice controls. Suggested best practices for control of construction noise include:
Noise-generating construction activities, including truck traffic coming to and from the construction site for any purpose, shall be limited to between the hours of 7:00 am and 7:00 pm. No construction shall occur on National holidays.

Environmental Setting
Existing Ambient Noise Levels
To establish baseline noise conditions, existing noise levels were monitored at four locations in the vicinity of the Project Site. The locations of the noise measurements are depicted in Figure 3.0-1, Noise Monitoring and Sensitive Receptor Location Map. The noise survey was conducted in December 2023 using the Larson Davis SoundTrack LxT (Type 1) sound level meter, which conforms to industry standards set forth in ANSI S1.4-1983 (R2006) – Specification for Sound Level Meters/Type 1. This instrument was calibrated and operated according to the manufacturer’s written specifications. At the measurement sites, the microphone was placed at a height of approximately five feet above grade. The results of the measurements are summarized in Table 3.13-4, Existing Noise Levels in the Vicinity of the Project Site. As shown in Table
3.13-4, the ambient noise levels ranged from 63.7 dBA Leq to 66.1 dBA Leq in the vicinity of the Project Site.
In addition, based on the measurement data collected at Location 1 (located on the eastern boundary of the
3.0 Environmental Checklist

Existing Vehicle Traffic Noise Levels
Existing roadway noise levels were calculated for primary roadway segments located in the vicinity of the Project Site. The roadways selected are representative of the segments that would be most impacted by an increase in traffic according to the Project’s transportation engineer.48 Calculations of the existing roadway noise levels are based on the Federal Highway Administration Highway Noise Prediction Model (FHWA-RD-77-108) and traffic volumes from the Project’s Transportation Analysis.49 The model calculates the average noise level at specific locations based on traffic volumes, average speeds, roadway geometry, and site environmental conditions. The average vehicle noise rates (energy rates) utilized in the FHWA Model have been modified to reflect average vehicle noise rates identified for California by Caltrans. The Caltrans data show that California automobile noise is 0.8 to 1.0 dBA higher than national levels and that medium and heavy truck noise is 0.3 to 3.0 dBA lower than national levels. The average daily noise levels along study area roadway segments are presented in Table

generate groundborne vibration velocity levels of around 63 VdB at 50 feet, and these levels could reach 72 VdB where trucks and buses pass over bumps in the road.50 In terms of PPV levels, a heavy-duty vehicle traveling at a distance of 50 feet can result in a vibration level of approximately 0.001 inch per second.
Noise Sensitive Receptors
Noise-sensitive land uses are generally considered to include those uses where noise exposure could result in health-related risks to individuals, as well as places where quiet is an essential element of their intended purpose. Residential dwellings are of primary concern because of the potential for individuals to be exposed to increased and prolonged exposure to both interior and exterior noise levels. According to the City’s Noise Element, noise-sensitive uses include schools, hospitals, libraries, care facilities, and residential areas.51 The closest noise-sensitive receptors to the Project Site include: the existing Stratford School adjacent to the south of the Project Site; existing vacant land approximately to the west that is currently under construction and is anticipated to operate as a multi-family apartment complex by the time the Project begins operations (551 ft); Centre Pointe Drive apartments to the west of the Project Site (511 ft); and, the Capitol Apartments south of the Project Site (645 ft) (See Figure 3.0-1, Noise Monitoring and Sensitive Receptor Location Map.)
Would the project:
a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
Less than Significant Impact.
Construction Noise Impacts
Construction activities associated with the Project would result in temporary noise level increases in the vicinity of the Project Site on an intermittent basis and, as such, could expose nearby sensitive receptors to increased noise levels. The increase in noise at off-site sensitive receptors during construction of each phase of construction under the Project would be temporary in nature and would not generate continuously high noise levels, although occasional single-event disturbances from construction would occur. Construction noise would typically be higher during the heavier periods of initial construction (i.e., demolition and 50 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual. 2018.

grading work) and reduced in the later construction phases (i.e., interior building construction) because the physical structure of the buildings would break line-of-sight noise transmission from the construction area to the nearby sensitive receivers. Noise levels would fluctuate depending on the construction phase, equipment type and duration of use, distance between the noise source and receivers, and presence or absence of intervening structures, terrain, or other noise attenuation barriers.
Table 3.13-6, Estimated Construction Noise Levels, shows the maximum expected noise levels at sensitive receptors in the vicinity of the Project Site. The analysis shows the maximum noise levels from the use of equipment anticipated to be used during demolition, grading and building construction.

As shown in Table 3.13-6, construction activity would generate noise levels of up to 72.6 dBA Leq at the nearest existing sensitive receptor (Sensitive Receptor No. 4). As such, temporary construction noise would not exceed the FTA’s 80 dBA Leq daytime construction threshold. Furthermore, the Project would be consistent with Chapter 213 of Title V of the City’s Municipal Code, which prohibits construction activities outside of the hours of 7:00 a.m. to 7:00 p.m. on weekdays and weekends, and on holidays except during emergencies. It should also be noted that the Project would be required to comply with Noise Element Action N-1d, which requires the Project Applicant to implement standard best practices to limit construction noise levels to the extent feasible. Notwithstanding the implementation of best practices, because the Project would be consistent with the construction hours identified in the City’s Municipal Code and because Project construction noise would not exceed the FTA’s 80 dBA Leq daytime construction threshold, impacts would be less than significant.

Operational Noise Impacts
Traffic Noise
The Project would increase the number of vehicle trips within the vicinity of the Project Site which would increase traffic noise on roadways. To determine whether the Project would create traffic noise resulting in a significant noise increase, existing and potential future noise levels were calculated based on the FHWA Traffic Noise Model consistent with data provided by the Project’s transportation engineer52 (see Appendix C). The noise increases between the Existing and Existing Plus Project scenarios are shown in Table 3.13-7, Project Traffic Noise.

As discussed previously, where existing traffic noise levels are greater than 60 dBA Ldn and up to 65 dBA Ldn at the outdoor activity areas of noise-sensitive uses, a +3 dBA Ldn increase in roadway noise levels would be considered significant. Because the Project would increase local traffic noise levels by a maximum of 2.3 dBA Ldn along any segment, these thresholds would not be exceeded and impacts with respect to operational traffic noise would be less than significant. 52 Hexagon Transportation Consultants, Inc., 1323 Great Mall Drive Stratford School, Traffic Operations Analysis, January 8, 2024.

On Site Noise
Stationary Noise
The operation of the Project would generate on-site stationary noise from HVAC equipment. Noise from HVAC equipment serving the Project would typically generate noise in the range of 60 to 70 dBA Leq at a reference distance of 15 feet from the source.53 As discussed previously, noise-sensitive receptors are located at least 165 feet from the Project Site and noise from HVAC equipment would attenuate at a rate of approximately 6 dBA per doubling of distance from the source. Thus, HVAC related noise would not exceed 52 dBA Leq at the nearest sensitive receptor. As shown in Table 3.13-4, ambient noise levels in the Project Site vicinity were measured between 63.7 dBA Leq to 66.1 dBA Leq. Based on estimated noise level of 52 dBA Leq at 165 feet for HVAC equipment, noise levels from such equipment would not exceed ambient noise levels at off-site sensitive receptors. Furthermore, HVAC units are traditionally rooftopmounted and/or shielded from surrounding land uses, serving to block line-of-sight noise transmission to sensitive receptors. Impacts would be less than significant.
Playfield Noise
The proposed synthetic turf playfield would introduce noise sources associated with children playing. As noted above, the City’s noise ordinance generally limits the generation of noise that exceeds the actual measured existing ambient noise level by 3 dB(A) DNL at neighboring properties. The day-night average sound level (Ldn or DNL) is an average noise level over a 24-hour period. Noise levels occurring between the hours of 10:00 PM and 7:00 AM are increased by 10 decibels (dB). This noise is weighted to take into account the decrease in community background noise of 10 dB(A) during this period.
A noise measurement was taken at the existing Stratford School’s outdoor play area and noise levels reached 62.4 dBA Leq during typical play activities (see Appendix C for noise measurement data). As shown in Table 3.13-4 above, ambient noise levels in the Project Site vicinity were measured between 63.7 dBA Leq to 66.1 dBA Leq. Thus, noise associated with the playfield would not exceed ambient noise levels in the area. Furthermore, as no playfield activity would occur during evening hours, there would be no potential to increase the day-night average noise levels at neighboring properties by 3 dBA. Impacts would be less than significant.

Parking Noise
Operational noise sources are also associated with on-site parking and vehicle circulation, including delivery trucks and trash-hauling trucks. The Project is a K-12 preparatory school and would not cause a substantive increase in delivery or trash trucks in the Project area. Various noise events would occur periodically from the Project’s parking uses. Such periodic events would include activation of car alarms, sounding of car horns, slamming of car doors, engine revs, and tire squeals. It should be noted that the existing urban environment of the Project Site currently generates noise levels associated with these parking and vehicular noise sources. Although the Project would increase the number of vehicles parking in the area, the types of noise would be similar to those currently occurring in the vicinity of the Project Site. Parking-related noise for the existing Stratford School was observed during field noise measurements.
As detailed in Appendix C, parking noise levels were found to be 64.6 dBA Leq, which would be generally consistent ambient noise levels that range from 63.7 dBA Leq to 66.1 dBA Leq (see Table 3.13-4). Therefore, impacts would be less than significant.
b) Would the project result in exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels?
Less than Significant Impact.
Vibration Impacts
Construction activities associated with the Project could intermittently generate vibration in the Project Site vicinity when it reaches building walls and floors of sensitive receptors. Vibration-generating equipment could include bulldozers and loaded trucks to move materials and debris, jackhammers to break apart concrete, and caisson drills for foundations. Table 3.13-8, Vibration Source Levels for Construction Equipment, identifies vibration velocity levels for equipment at various distances from the source.

With respect to human annoyance, the FTA thresholds are 80 VdB at residences and buildings where people normally sleep, and 75 dB for institutional uses such as schools. With respect to building damage, the FTA guidelines consider 0.12 inch/sec PPV to be the significant impact level for buildings extremely susceptible to vibration damage, 0.2 inch/sec PPV to be the significant impact level for non-engineered timber and masonry buildings, 0.3 inch/sec PPV to be the significant impact level for engineered concrete and masonry, and 0.5 inch/sec PPV to be the significant impact level for reinforced-concrete, steel or timber.
Based on Table 3.13-8, construction equipment could reach vibration levels of 69 VdB at 100 feet. As such, the 80 VdB residential annoyance threshold would not be exceeded at the nearest residential receptor (Sensitive Receptor No. 2). In addition, the 75 VdB annoyance threshold for schools would not be exceeded at Sensitive Receptor No. 1. It should also be noted that construction-related vibration levels experienced would be temporary and intermittent and the Project would be consistent with Title V, Chapter 213 of the City’s Municipal Code, which prohibits construction activities outside of the hours of 7:00 a.m. to 7:00 p.m. on weekdays and weekends, and on holidays except during emergencies. As such, construction-related vibration would not disturb residences during sensitive nighttime hours. Therefore, this impact would be less than significant.
Based on Table 3.13-8, construction equipment would reach a maximum of 0.011 PPV (in/sec) at 100 feet.
The building nearest the Project Site is the existing school building 165 feet south on Falcon Drive. These vibration levels would not exceed the most conservative 0.12 inch/sec PPV threshold for buildings extremely susceptible to vibration damage. As such, construction-related vibration impacts with respect to building damage would be less than significant.

c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
No Impact. The Project Site is not located in the vicinity of a private airstrip or airport land use plan. The closest airport to the Project Site is the Norman Y. Mineta San Jose International Airport located approximately 5.4 miles southwest of the Project Site. Additionally, the Project Site is located outside of the Airport Influence Area of the Norman Y. Mineta San Jose International Airport Comprehensive Land Use Plan.54 Therefore, the Project would not expose residents at the Project Site to excessive airport-related noise levels.
No impact would occur in this regard.

Would the project:
a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
Less than Significant Impact. A Project could induce population growth in an area either directly, through the development of new businesses, or indirectly, through the extension of roads or other infrastructure.
The Project does not include the addition or removal of housing and thus would have no direct impact on population and housing forecasts for the area. Although the Project would increase the number of students and employees at the Project Site, it is anticipated that the future students and employees would primarily consist of existing residents in the Milpitas area. Estimating the number of families of future students and employees who may choose to relocate to the City would be highly speculative, since many factors influence personal housing location decisions (e.g., family income levels and the cost and availability of suitable housing in the local area). Nevertheless, in an effort to present a worst-case population growth scenario, this analysis assumes the Project would enroll a maximum of 500 students and employ 75 fulltime employees, all of whom would permanently relocate to the City.
Based on the City’s average household size of 3.13 persons, the Project could result in a maximum population increase of approximately 1,800 persons.55 As of 2023, the City has an estimated population of 81,067 persons.56 According to the City’s General Plan Update Environmental Impact Report, the City’s 55 California Department of Finance, Demographic Research Unit, “E-5 Population and Housing Estimates for Cities, Counties, and the State, January 2021-2022, with 2020 Benchmark.” May 2022. 56 California Department of Finance Demographic Research Unit, “E-5 Population and Housing Estimates for Cities, Counties, and the State, January 2021-2022, with 2020 Benchmark.” May 2022.

Impact Sciences, Inc. 3.0-95 Stratford Preparatory School Project 1451.002 May 2024
population is forecasted to reach an estimated 113,530 persons by the year 2040, representing a total increase of 31,933 persons.57 The Project’s potential maximum increase of 1,800 persons would represent approximately six percent of the City’s projected increase in population between the years 2023 and 2040 (32,463 persons). However, this conservative estimate is based on the assumption that the maximum number of students and employees would be new to the City. It is more likely that the majority of the students are currently in attendance in the existing lower division Stratford school campuses. Furthermore, as discussed in Section 11, Land Use and Planning, the Project would be consistent with its designated land use under the MMSP as a BPRD-R. Thus, the anticipated population generation has been accounted for in the City’s long-range planning documents. Therefore, the Project would not induce substantial unplanned population growth in an area, either directly or indirectly, and impacts would be less than significant.
Mitigation Measures: No mitigation measures are required. b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
No Impact. The Project would renovate an existing vacant office building into a new preparatory school and construct a new gymnasium and playfield. There are no existing residential facilities on-site. Thus, the Project would not displace substantial numbers of existing people or housing, and no impacts would occur.
Mitigation Measures: No mitigation measures are required. 57 City of Milpitas. The City of Milpitas General Plan Update Environmental Impact Report, November 2020. Available online at: https://www.milpitas.gov/DocumentCenter/View/1168/Draft-EIR-PDF?bidId=. Accessed January 2, 2024.

v. Other public facilities?
a) Fire protection?
Less than Significant Impact. Fire protection and other related services to the Project Site are provided by the Milpitas Fire Department (MFD). There are four fire stations in the City. The MFD offers fire protection and emergency services to the City, including fire suppression services, emergency medical services, rescue services, hazardous and toxic materials emergency response, coordination of City-wide disaster response efforts, enforcement of fire and life safety codes, enforcement of State and Federal hazardous materials regulations, and investigation of fire cause, arson and other emergency events for reason and origin.58 The closest fire station to the Project Site is Fire Station One, located approximately 0.68 miles northwest of the Project Site.
As discussed in Section 14, Population and Housing, the Project would not result in a substantive increase in population within the City, nor would it generate growth beyond what has been accounted for in the City’s long-range planning documents. Thus, the Project would not substantively increase the service population or demand for fire protection services. The Project would utilize the existing driveways along Great Mall Drive and Falcon Drive, which can accommodate emergency vehicles that are entering the Project Site. Additionally, a new fire service line would be installed and would connect to the existing water 58 City of Milpitas, “Fire,” Available online at: https://www.milpitas.gov/milpitas/departments/fire/, accessed January 11, 2024.

mains located along Great Mall Drive. The proposed fire line and the overall Project design would be in accordance with the applicable design standards outlined in the 2022 California Building Code (CBC), Chapter 9, Fire Protection and Life Safety Systems. The Project would also be designed in accordance with the City’s Municipal Code, Chapter 300 (Fire Code) which adopts by reference the 2022 editions of California Fire Code and the California Fire Code. The California Fire Code includes fire safety-related building standards for construction, access, water mains, fire flows, and hydrants. As such, impacts on fire protection services and facilities would be less than significant.
Mitigation Measures: No mitigation measures are required. b) Police protection?
Less than Significant Impact. Law enforcement protection services for the City of Milpitas are provided by the Milpitas Police Department (MPD). The MPD station is located 2.62 miles north of the Project Site at 1275 North Milpitas Boulevard.
Construction activities associated with the Project may create a temporary increase in demand for MPD services at the construction site. However, construction activities would be required to comply with the emergency site access requirements outlined in the 2022 CBC. Project implementation would result in an increase in individuals on-site, potentially resulting in increased calls for service and traffic and trafficrelated calls for the proposed school. However, as discussed in Section 14, Population and Housing, the Project would not result in a substantive increase in population within the City, nor would it generate growth beyond what has been accounted for in the City’s long-range planning documents. Thus, the Project would not substantively increase the service population or demand for police fire protection services. The Project would have a total of five pedestrian access gates to the school grounds, each equipped with security locks to minimize potential criminal activity on-site. Further, the Project Site is currently within the MPD’s service area and thus, the Project would not extend MPD’s resources and staffing beyond their existing service area. As such, impacts to police protection and services would be less than significant.
Mitigation Measures: No mitigation measures are required. c) Schools?
No Impact. As stated, the projected indirect population growth in the City from the Project would be nominal. The Project would provide an additional secondary school and would not warrant additional schools in the area. As such, no impacts to school facilities would occur.
Mitigation Measures: No mitigation measures are required.

d) Parks?
No Impact. The closest public park to the Project Site is Parc Metro Clubhouse, located 0.58 miles north of the Project Site at 330 Curtis Avenue.
59 As stated, the Project would not result in a substantial increase in the City’s population and would not substantially increase the use of the City’s parks and recreational facilities. As such, no impact would occur.
Mitigation Measures: No mitigation measures are required. e) Other Public Facilities?
Less than Significant Impact. The City of Milpitas is served by the Santa Clara County Public Library District (County Library District). The County Library includes eight branch libraries that provide services to Santa Clara County.60 The closest public library to the Project Site is the Milpitas Library (MPL), located approximately 1.46 miles northwest of the Project Site at 160 North Main Street.
As stated above, the Project is not expected to result in a substantial increase in population compared to existing conditions. Thus, the Project is not expected to result in an additional demand for library services.
Therefore, less than significant impacts would occur.

Pedestrian and Bicycle Facilities
Off-site pedestrian facilities that surround the Project Site are limited to sidewalks located along Great Mall Drive and Great Mall Parkway. All intersections adjacent to the Project Site provide marked crosswalks and curb ramps on most approaches. Additionally, Great Mall Parkway is identified by the City of Milpitas as an existing Class II Bike Lane and as an existing trailway that is prioritized for improvement.61 Project construction would not disturb the surrounding pedestrian facilities as all associated construction activities/staging equipment would occur on-site. With respect to operations, the Project Site includes direct pedestrian connections to the nearby Milpitas BART Station (see Appendix D, Transportation Impact Analysis). The Project would install pedestrian/bike gates that would provide access for students walking along all adjacent roadways. Pedestrians and bicyclists travelling to/from the Milpitas BART station would 61 City of Milpitas, City of Milpitas Bicycle/Pedestrian & Trails Plan, Adopted May 2022. Available online at:

maintain access to the Project Site. As such, the Project would not remove any pedestrian facilities, nor would it conflict with the City of Milpitas Trail, Pedestrian and Bicycle Master Plan.
According to Appendix D, the volume of cyclists generated by the Project would not exceed the carrying capacity of the existing bike facilities surrounding the site, nor would Project implementation require additional bicycle facilities. Rather, the Project would provide bicycle parking spaces on-site for students and staff. Thus, the Project would not conflict with the City’s Trail, Pedestrian and Bicycle Master Plan.
Transit Systems
The Project Site is surrounded by several stops for light rail and public transit lines provided by the Valley Transportation Authority (VTA), Alameda-Contra Costa Transit District (AC,) and the San Francisco Bay Area Rapid Transit District (BART) (see Appendix D).62 The closest VTA bus stop is located approximately 275 feet southwest from the Project Site along Great Mall Parkway and 0.20 miles northwest at the intersection of Great Mall Parkway and McCandless Drive. Additionally, the Project Site is located less than
0.50 miles from the nearest major transit stop. The closest major transit stops include Milpitas BART Station and the VTA Great Mall/ Main Station. Thus, the Project Site is located within a Transit-Oriented Development (TOD) area.63
The Project would introduce new students and staff to the Project area. Thus, the Project would generate additional transit trips in the Project area. However, according to Appendix D, the volume of transit trips generated by the Project is not expected to exceed the carrying capacity of the existing transit services to the site. The Project, by itself, would not require additional transit service to the area or improvements to existing transit service frequencies. Thus, the Project would not require conflict with existing or proposed transit projects or policies identified by the VTA.
In conclusion, the Project would not conflict with the plans or policies addressing the circulation system of the transit, roadway, bicycle and pedestrian facilities. Less than significant impacts would occur.

b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? Less than Significant Impact.
CEQA Guidelines Section 15064.3(b) provides considerations for evaluating a project’s transportation impacts. Land Use Projects (b)(1) are evaluated through vehicle miles traveled (VMT). Generally, projects within one-half miles of either an existing major transit stop or a stop along an existing high quality transit corridor should be presumed to cause a less than significant transportation impact.64 Projects that decrease VMT in the project area compared to existing conditions should be presumed to have a less than significant transportation impact.
On May 18, 2021, the City of Milpitas adopted a local transportation policy analysis for VMT, the City of Milpitas Transportation Analysis (dated March 2022), to comply with State law and provide established and consistent criteria for analyzing transportation impacts of development projects and long-range plans. The transportation policy is intended for evaluating potential transportation impacts of new developments to comply with the California Environmental Quality Act (CEQA). The City has established thresholds of significance for non-residential Projects that are in accordance with the Office of Planning and Research (OPR). According to the City of Milpitas Transportation Analysis, a project shall be presumed to have a lessthan-significant transportation impact of they meet any of the following screening criteria:
• Small Project Screening: Projects generating 110 daily trips or less. Examples: Single-family residential development of 12 units or fewer, multi-family residential development of 20 units or fewer, and office developments of 10,000 square feet or less.
• Retail projects that are local serving defined as 100ksf or less; • Local serving public projects such as fire stations, neighborhood parks, libraries, and community centers;
• Transit Supportive Project transit screening: All land-use projects located within one half mile of a major transit stop, or a stop along a high-quality transit corridor, pursuant to State definitions for such facilities and meet the following criteria;
− For Office/R&D projects, a minimum floor area ratio of 0.75 64 California Office of Planning and Research, Technical Advisory on Evaluating Transportation Impacts in CEQA, 2018.

− For Residential projects, a minimum density of 35 units/acre (40 units/acre in the Serra Center and 50 units/acre in the Milpitas Metro Specific Plan area); − No excess parking: the project does not include more parking for use by residents, customers, or employees of the project than required by the Municipal Code; − No loss of affordable dwelling units: the project does not replace affordable residential units with a smaller number of affordable units, and any replacement units are at the same level of affordability; and
• Projects with restricted affordable housing.
Project Screening
Appendix D determined that the Project could potentially be screened out of the VMT Analysis, as the proposed school use would qualify the Project to be screened out of VMT Analysis under the following screening criteria identified in the City of Milpitas Transportation Analysis:
• Local Serving Project: As stated above, the City of Milpitas Transportation Analysis Policy Guidelines (March 2022) presumes that local serving public projects would have a have a less-than-significant transportation impact. The Governor’s Office of Planning and Research (OPR) Technical Advisory (December 2018) states that “By adding retail opportunities into the urban fabric and thereby improving retail destination proximity, local-serving retail development tends to shorten trips and reduce VMT. Thus, lead agencies generally may presume such development creates a less-thansignificant transportation impact.” Appendix D states that school uses are similar to retail uses, in that, the more schools that are located within in a given area, the shorter the student trips between the school and other complementary land uses (such as employment or residential uses). • Prior Approvals: The Project Site is located within the MMSP planning area. The Project Site is designated as BPRD-R and educational uses are listed as an acceptable use in BPRD-R designated areas under the MMSP. Thus, the proposed educational use was contemplated as a potential development on-site under the MMSP. According to Appendix D, CEQA impacts related to traffic for projects that are consistent with the MMSP have been analyzed in the Supplemental Environmental Impact Report (EIR) for the MMSP. As such, the Project may qualify for a statutory exemption under CEQA.
Therefore, given the City’s screening criteria, prior finding regarding private school projects, and that the use for the site is already cleared environmentally, the impacts of the project on VMT are considered less than significant.

VMT Analysis
The Project would implement a new school with a maximum student enrollment of 500 students and 75 employees. The VMT Analysis (Appendix D) determined that implementation of the Project would decrease the VMT per employee (VMT/employee) from 2,635 VMT/employee to 1,163 VMT/employee.
As a new secondary school for 6th through 12th graders, the Project would be the only Stratford secondary school for three existing lower division Stratford preparatory schools located within a three-mile distance from the Project Site. According to Appendix D, the Project would provide an alternate location for Stratford school students to continue their education without traveling to a more distant location, thus reducing VMT per capita from existing conditions. Thus, the Project’s overall impact on VMT would be less than significant.
Mitigation Measures: No mitigation measures are required. c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less than Significant Impact. The Project would not include any on-site or off-site roadway improvements.
The majority of the existing on-site circulation would be maintained with implementation of the Project.
The Project would utilize the two existing driveways off of Great Mall Drive and Falcon Drive. Visitors would use the existing driveway off of Great Mall Drive as the primary vehicular entry to the Project Site.
As illustrated in Figure 2.0-5, upon entering the school grounds, visitors may either turn right to park within the proposed 21 parking spaces located at the northwestern corner of the Project Site or turn left towards the remaining on-site parking spaces or towards the proposed drop-off and pick up-zone for students along the northern frontage of the school. As depicted, vehicles would then continue through the proposed egress route and exit the Project Site through the security gate along the southern perimeter of the site to the parking lot of the existing adjacent school, or through the existing driveway along Falcon Drive. The Project would be required to comply with all on-site circulation site access requirements imposed by the City and the Milpitas Fire Department (MFD). As such, Project plans would be subject to review by the City and the MFD. Upon approval, the Project would not include any geometric design features or incompatible uses that would substantially increase hazards. Impacts would be less than significant.
Mitigation Measures: No mitigation measures are required.

d) Result in inadequate emergency access?
Less than Significant Impact. Construction activities would remain on-site. The Project would utilize the existing driveways on-site for emergency access. The Project would incorporate all applicable design and safety standards and regulations outlined in Chapter 33 of the 2022 California Building Code, and Chapter 11 (Construction Requirements for Existing Buildings) of the California Fire Code. Furthermore, the Project would be subject to site plan review by the City and MFD to ensure that on-site emergency access points are sufficient. Upon site plan approval, and by adhering to applicable state requirements, impacts regarding emergency access would be less than significant.
Mitigation Measures: No mitigation measures are required.

In compliance with AB 52, the City will distribute letters notifying each tribe that may have knowledge of cultural resources within the Project Area in coordination with the circulation of this MND.
Ground disturbing activities associated with the Project could result in the discovery of previously undiscovered cultural resources. This includes potential discovery of tribal cultural resources. In the event Native American resources are discovered, the City would consult with the Native American monitor and affected tribe(s). Additionally, as stated in Section 5, Cultural Resources, in the event that human remains are encountered, Mitigation Measure CUL-1 would ensure that work in the immediate area of a potential archaeological find is halted until an archaeologist evaluates the find and determines appropriate subsequent procedures. With implementation of Mitigation Measure CUL-1, impacts to resources that are applicable under Public Resources Code Section 5024.1 would be reduced to less than significant levels.

Water
The City provides water services to the Project Site and receives water supplies from the San Francisco Public Utilities Commission (SFPUC) and Valley Water (formerly Santa Clara Valley Water District). The SFPUC is a regional wholesale water supplier that supplies predominantly snowmelt from the Sierra

Nevada, delivered through the Hetch Hetchy aqueducts.
65 Valley Water is a countywide wholesale water
and groundwater management agency, relies on local retailers (municipalities and private companies) to deliver water to homes and businesses throughout the county, including the City of Milpitas.66 Potable water is currently being conveyed to the Project Site with the existing underground waterlines that connect to a 12-inch water main along Great Mall Drive. The Project would continue to use the existing water lines on-site to receive potable water for the landscaping, restrooms, and kitchens. The proposed gymnasium would not include uses that need potable water. The Project Site is designated in the City’s General Plan as Milpitas Metro Specific Plan (MMSP), and in the MMSP, the Project Site is designated as Business Park Research & Development, Limited Residential (BPDR-R), which supports and allows educational uses. Therefore, the expected development intensity of the Project has been accounted for in the City’s long-range planning documents. As such, the Project would not require new or relocated or expanded water facilities.
Wastewater
The Project would include the construction of new bathrooms within the existing building, which would generate additional demand for wastewater treatment. No bathrooms are being proposed within the new gymnasium. Wastewater produced by the Project would be treated at the San Jose-Santa Clara Regional Wastewater Facility (RWF), located 1.23 miles southwest of the Project Site in the City of San Jose. The proposed school would construct a new 6-inch sewer lines to connect to the City’s 8-inch main and new 6- inch and 8-inch storm drains will collect water and then route to a detention basin, which will then drain into a private storm drain system along Great Mall Drive. A new Recycled Water system will need to be constructed in order to provide irrigation to the landscape areas. A connection to the existing 8-inch Recycled Water Main on Falcon Drive will be established.
The RWF has a total contracted peak flow capacity of 14.25 million gallons per day (mgd).67 The Project is anticipated to generate approximately 570 gallons per day.68,69 The anticipated wastewater generated by 65 City of Milpitas, 2020 Urban Water Management Plan, 2021. Available online at:

3.0 Environmental Checklist
Impact Sciences, Inc. 3.0-110 Stratford Preparatory School Project 1451.002 May 2024
the Project would represent less than one percent of the City’s contracted peak flow for the RWF. As such, the existing wastewater treatment capacity is anticipated to be sufficient to accommodate the Project. The Project is consistent with the Project Site’s land use designation under the MMSP and therefore its development intensity and its wastewater generation have already been accounted for in the City’s long range planning documents. Thus, the Project would not require the relocation or construction of new or expanded wastewater treatment facilities and impacts related to wastewater conveyance would be less than significant.
Stormwater
Stormwater runoff from the Project Site is currently conveyed off-site by the City’s stormwater drainage system. Compared to existing conditions, the Project would increase the amount of impervious surfaces at the Project Site. However, the Project would implement a new stormwater system to offset the increase in stormwater resulting from the new gymnasium building. The Project would install new storm drain lines that would drain runoff into a new planter area and would act as a bioswale for treatment. The Project would also adhere to local regulations to ensure that stormwater pollution from the Project would be minimized. The proposed stormwater design features and adherence to applicable requirements would reduce the Project’s impacts to the City’s stormwater system to less than significant levels.
Electricity, Natural Gas, or Telecommunications
According to the MMSP, Pacific Gas & Electric (PG&E) provides electric services to properties within the planning area, including the Project Site. The Project would utilize the existing electricity, natural gas, and telecommunication lines and services at the Project Site. Payment of standard utility connection fees and ongoing user fees to PG&E would be required to ensure these utility services would be able to accommodate the proposed gymnasium. Payment of these standard fees would ensure that Project impacts to dry utility services would be less than significant.
Mitigation Measures: No mitigation measures are required. b) Have sufficient water supplies available to serve the Project and reasonably foreseeable future development during normal, dry, and multiple dry years? Less than Significant Impact. Valley Water provides treated water from its Penitencia and Santa Teresa treatment plant via its Milpitas Pipeline which terminates in the City. Although the City’s purchases are currently limited to surface water largely purchased by Valley Water from the State Water Project and Central Valley Project, Valley Water’s overall water supply comes from a variety of sources. Nearly half is from local groundwater aquifers, and more than half is imported from the Sierra Nevada through pumping

stations in the Sacramento-San Joaquin River Delta. Both groundwater and imported water are sold to retailers.
According to the City’s 2020 Urban Water Management Plan (UWMP), the total storage of both the Penitencia and Santa Teresa treatment plant combined is 170,000 acre-feet (AF). Further, the City is projected to have a water demand and supply of 4,917-acre feet per year (AFY) by the year 2045 during normal, dry, and multiple dry years. According to Appendix A, Air Quality and Greenhouse Gas Data, the Project would generate a water demand of approximately 2,648,705 gallons per year or 7,256 gallons per day (gpd) (or 8.12 AFY). Thus, the Project would represent less than one percent of both the City’s water demand and supply, as well as the treatment capacity of both the Penitencia and Santa Teresa treatment plant. As such, impacts would be less than significant.
Mitigation Measures: No mitigation measures are required. c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Less than Significant Impact. As discussed above, the Project would not require the relocation or construction of new or expanded wastewater treatment facilities. The Project involves the renovation of an existing office building into a new preparatory school and the construction of a new gymnasium and turf playfield. As stated, the Project would result in an increase in demand for wastewater treatment compared to existing conditions. However, the Project is not anticipated to be a substantial source of wastewater.
Based on available data, it is anticipated that the RWF has adequate capacity to serve the Project’s projected demand for wastewater treatment. Therefore, the Project’s impacts to wastewater treatment would be less than significant.
Mitigation Measures: No mitigation measures are required. d) Generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Less than Significant Impact. Approximately 75 percent of total solid waste generated within the City is disposed at the Newby Island Sanitary Landfill and Monterey Peninsula Landfill.70 The Newby Island Landfill permits 4,000 tons of solid waste per day and a remaining capacity of 16,400,000 tons of solid 70 CalRecycle, “Jurisdiction Disposal and Alternative Daily Cover (ADC) Tons by Facility.” Available online at:

waste.71 The Monterey Peninsula Landfill permits 3,500 tons of solid waste per day and a remaining capacity of 48,560,000 tons of solid waste.
Construction activities associated with the Project would generate approximately 221. 5 tons of debris, 153.5 tons of which would be recycled. However, the amount of waste generated by the Project would not exceed the amount of waste permitted or the capacities of the Newby Island Sanitary Landfill and Monterey Peninsula Landfill. Additionally, solid waste generation from the Project’s construction activities would be temporary and would cease upon completion of the Project. The Project would generate approximately
45.5 tons of waste per year (or 0.12 ton per day). Accordingly, the Project would represent less than one percent of the daily permitted and remaining capacities for solid waste for both landfills. Therefore, the Project would not generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure. Less than significant impacts would occur.
Mitigation Measures: No mitigation measures are required. e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
Less than Significant Impact. As stated above, the Project would not generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure. Furthermore, the Project would demonstrate compliance with the California Integrated Waste Management Act of 1989 (Assembly Bill [AB] 939), which requires all California cities to “reduce, recycle, and re-use solid waste generated in the State to the maximum extent feasible.” AB 939 requires that at least 50 percent of waste produced is recycled, reduced, or composted. The Project would also comply with the 2022 CALGreen Code, which includes design and construction measures that help reduce construction-related waste through material conservation and other construction-related efficiency measures. Thus, less than significant impacts would occur.

The Project does not propose any off-site improvements, and all construction activities, staging, and equipment would occur on-site. Additionally, the Project Site plans would be reviewed by the Milpitas Fire Department prior to approval. Thus, the Project would not interfere with the City’s EOP, and impacts would therefore be less than significant. 72 City of Milpitas, Emergency Operations Plan of Milpitas. August 2021.

Mitigation Measures: No mitigation measures are required. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
No Impact. Wildfires have the potential to occur not only in fire-prone undeveloped areas, but also in developed areas where existing transmission lines, lightning strikes, lawn equipment operated over dry grass, fireworks, and even arson may ignite a wildfire. Wildfires pose a significant public health risk due to their air quality impacts, particularly with regard to smoke and particulate matter exposure. This risk persists even after a wildfire is extinguished because particulate matter from fire ash can be picked up by winds.
The Project Site is not located within a Very High Fire Hazard Zone (VHFHZ), nor does the Project Site contain vegetation that could contribute to the uncontrolled spread of wildfire.73 The nearest VHFHZ includes the open hillsides of Milpitas, located more than ten miles to the east of the Project Site.74 Therefore, given the urbanized location of the Project Site, the Project would not exacerbate wildfire risks and would therefore result in no impact.
Mitigation Measures: No mitigation measures are required. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? No Impact. The Project Site is urbanized and does not include wildlands or high fire terrain. The Project Site is surrounded by existing structures and infrastructure including roadways and interstate highways and would not require the installation or maintenance of roads, fuel breaks, emergency water or other sources that could exacerbate fire risk. Due to the urbanized nature of the Project Site and surrounding area, it is unlikely any fire would spread and would therefore result in no impact.

d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? No Impact. In Northern California, intense rainfall may occur during the winter months, creating natural flooding events when the ground is saturated and water levels are high. This has the potential for flooding issues, and fire hazards may exacerbate such flooding and debris flows along waterways. Since debris flows may occur quickly and without warning, such flows can damage structures, block drainage or even sweep away vegetation resulting in tenuous post-fire slope stability. Fast moving debris flows can be one of the most dangerous post-fire hazards. The Project Site is generally flat and urbanized, is not in an area of wildfire risk, and would not be subject to any post fire slope instability or landslides. Therefore, there would be no impact.
Mitigation Measures: No mitigation measures are required.

Impact
No
Impact
a. Does the project have the potential to degrade the
quality of the environment, substantially reduce the
habitat of a fish or wildlife species, cause a fish or
wildlife population to drop below self-sustaining
levels, threaten to eliminate a plant or animal
community, reduce the number or restrict the range of
a rare or endangered plant or animal or eliminate
important examples of the major periods of California
history or prehistory?
b. Does the project have impacts that are individually
limited, but cumulatively considerable?
(“Cumulatively considerable” means that the
incremental effects of a project are considerable when
viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?
c. Does the project have environmental effects which
will cause substantial adverse effects on human
beings, either directly or indirectly?
a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
Less than Significant Impact with Mitigation Incorporated. As discussed in Section 3, Air Quality, the Project will not exceed regional emission thresholds. Furthermore, consistent with BAAQMD requirements, the Project would implement Mitigation Measure AQ-1 to ensure impacts remain less than significant. As discussed in Section 8, Greenhouse Gas Emissions, the Project would not generate greenhouse gas emissions that would result in a significant impact on the environment, nor conflict with an applicable plan, policy, or regulation for reducing GHG emissions. Implementation of Mitigation Measure GHG-1 would demonstrate the Project’s compliance with the Milpitas 2022 CAP Update; and ensure impacts are less than significant.
3.0 Environmental Checklist
Impact Sciences, Inc. 3.0-117 Stratford Preparatory School Project 1451.002 May 2024
As discussed in Section 4, Biological Resources, the Project could potentially disturb and modify critical habitats that may be present on-site for special-status bird species. As such, implementation of Mitigation Measure BIO-1 would ensure that the impacts to the critical habitat of special-status bird species would be reduced to less than significant.
As discussed in Section 5, Cultural Resources, Section 7, Geology and Soils, and Section 18, Tribal Cultural Resources, ground disturbing activities associated with the Project may potentially uncover cultural, archaeological, or paleontological resources. As such, implementation of Mitigation Measures CUL-1 and GEO-1 would reduce these potential impacts to less than significant levels. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?
Less than Significant Impact with Mitigation Incorporated. The Project generally would not contribute to potentially cumulatively considerable impacts. As indicated in the above analysis, with implementation of the required mitigation measures, the Project would not result in any unmitigated significant adverse impacts and/or cumulatively considerable impacts. Specifically, Mitigation Measures AQ-1, BIO-1, CUL1, GHG-1, and GEO-1, would reduce potentially significant impacts to less than significant levels. The Project does not include any unmitigated cumulatively considerable impacts when considered in connection with the effects of past, present and probable future projects. No further analysis is necessary. c) Does the project have environmental effects, which would cause substantial adverse effects on human beings, either directly or indirectly?
Less than Significant Impact with Mitigation Incorporated. As indicated in the above analysis, with implementation of the required mitigation measures, the Project would not result in any unmitigated significant adverse impacts. Thus, the Project would not have the potential to result in substantial adverse effects on human beings.

PROJECT LOCATION
The Project is located at 1323 Great Mall Drive in the southern portion of the City of Milpitas (Project Site) (Assessor Parcel Number [APN] 086-24-046). The Project Site is located approximately
0.70 west of Interstate 680 (I-680), 0.90 miles west of I-880, and 428 feet north of Montague Expressway (see Figure 1, Regional Location and Figure 2, Project Site).
2 PROJECT DESCRIPTION
The Stratford Preparatory School Project (Project) proposes to redevelop the existing building on-site into a new preparatory school. The Project would also demolish the existing surface parking lot to construct a new 7,883 square foot gymnasium building that would be located west of the remodeled existing building. Supporting rooms for the gymnasium, such as locker rooms, gymnasium storage, a gymnasium office, and restrooms will be located in the southwestern corner of the existing building. The Project would accommodate students from the existing Stratford School facility located south of the Project Site. The Project would be equipped with 41 classrooms (general/biochemistry/art/physical engineering), eight offices, four media common rooms, a library, and a theater. Additionally, the Project would include supporting components, such as a new trash enclosure and a 14,695 square foot artificial turf playfield located to the west of the new gymnasium building (see Figure 3, Conceptual Site Plan).

Re: Stratford Preparatory School Project, Santa Clara County To Whom It May Concern:
A record search of the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) was completed for the information you have submitted for the above referenced project. The results were negative. However, the absence of specific site information in the SLF does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites.
Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated; if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received.
If you receive notification of change of addresses and phone numbers from tribes, please notify me. With your assistance, we can assure that our lists contain current information.
If you have any questions or need additional information, please contact me at my email address: [email protected].
Sincerely,
Cody Campagne

Transportation Impact Analysis
Memorandum
Date: May 28, 2024
To: Mr. Roberto Alanzo, City of Milpitas
From: Brett Walinski
Trisha Dudala
Subject: Transportation CEQA Analysis for the Stratford Preparatory School at 1323 Great Mall Drive in Milpitas, California
The purpose of this report is to analyze the transportation-related impacts of the proposed Stratford School located at 1323 Great Mall Drive in Milpitas, California, as required by the California Environmental Quality Act (CEQA). The project proposes a new preparatory school for 500 students in grades 6 to 12 to be located on the site of an existing office building. The site is located just north of the existing Stratford school with grades pre-kindergarden to 8. The project would renovate the existing 51,740 square-foot office building for school use and modify the existing site, which currently consists mostly of paved surface parking areas, into a campus with 14,965 square feet of synthetic turf (play field) and a new gym building of 7,883 square feet. Initial enrollment for the proposed school may begin in grades 6 to 12 with the intent to transition to Grades 9 to 12.
It is also an in-fill project and further completes the urban fabric of the city without requiring the expansion of services to unincorporated areas. The project falls within the boundaries of the recently adopted Milpitas Metro Specific Plan (MMSP) and is within the Great Mall District sub-area.
Its land use classification in the MMSP is “Business Park Research & Development Limited Residential (BPRD-R).” The BPRD-R land use classification specifically identifies “educational uses” as allowed uses.
The implementation section of the MMSP states that “Property owners in the Great Mall District have expressed interest in developing a mix of land uses that may occur over time rather than immediately. The plan aims to be responsive to developer needs while ensuring that the development of the parcel results in a high-quality, well-integrated, pedestrian-accessible urban node.”
This report includes an analysis of Vehicle Miles Travelled (VMT); potential impacts to pedestrian, bicycle and transit facilities; and emergency access.
VMT Analysis
Senate Bill 743 (SB 743) requires local jurisdictions to use Vehicle Miles Traveled (VMT) instead of Level of Service (LOS) to analyze transportation impacts under the California Environmental Quality Act (CEQA). City staff developed a new citywide VMT policy to comply with State law and provide established criteria for analyzing transportation impacts of development projects and long-range plans. The Milpitas City Council adopted the VMT policy on May 18, 2021, which establishes VMT as the methodology for measuring potential transportation environmental impacts and provides significance thresholds for CEQA analysis of future projects. The VMT policy aligns with the goals
1323 Great Mall Drive – Transportation CEQA Analysis May 28, 2024 Page | 2
and policies of the General Plan and adopted plans, and supports new development in suitable areas near transit, mixed-use neighborhoods, and other amenities.
VMT Policy
According to the City VMT policy, projects shall be presumed to have a less-than-significant transportation impact if they meet any of the following screening criteria:
• Projects generating 110 daily trips or less. Examples are single-family residential development of 12 units or fewer, multi-family residential development of 20 units or fewer, and office developments of 10,000 square feet or less.
• Retail projects that are local serving defined as 100,000 square feet or less. • Local serving public projects such as fire stations, neighborhood parks, libraries, and community centers.
• All land use projects located within one-half mile of a major transit stop, or a stop along a high-quality transit corridor (pursuant to State definitions for such facilities) and meet the following criteria:
o A minimum floor area ratio of 0.75; or for residential projects, a minimum density of 35 units/acre (40 units/acre in the Serra Center and 50 units/acre in the Milpitas Metro Specific Plan area).
o The project does not include more parking than required by City Code for use by residents, customers, or employees.
o The project does not replace affordable residential units with a smaller number of affordable units, and any replacement units are at the same levels of affordability. o The project is consistent with the applicable Sustainable Communities Strategy (SCS).
• Projects with restricted affordable housing (as described in the policy).
In addition, the City policy establishes the following:
• The Santa Clara County areawide average VMT shall be the regional baseline. • For residential, office and industrial projects, a project will have a less than significant impact if the project results in a 15% VMT reduction compared to the baseline. For industrial projects, the 15% threshold applies to the employee commute trip only. • Retail projects which result in a net increase in total VMT shall constitute a significant impact; however, retail projects determined by the city to be local serving are exempt from VMT analysis. In all cases, retail projects larger than 100,000 square feet may be considered regional-serving and would be subject to the retail threshold of significance. • Each land use within a mixed-use project, and all other project types, shall be evaluated independently by applying the most appropriate threshold of significance to each land use type being proposed.

• Projects that are currently approved will not require any supplemental VMT environmental review unless the “Project” requires supplemental environmental review not covered by an addendum.
• For projects such as regional retail, hospitals, stadium, sports complexes, or schools not regulated by a public-school district or that require permits from local jurisdiction, a net increase in total VMT may indicate a significant transportation impact.
The City VMT policy does not directly address how redevelopment projects are to be treated. The State criteria does. The state guidance is as follows: “Where a project replaces existing VMTgenerating land uses, if the replacement leads to a net overall decrease in VMT, the project would lead to a less-than-significant transportation impact.” Project VMT Screening
The proposed school project could potentially be screened out based on the “Local Serving” and “Prior Approvals” criteria as described below.
Local Serving
The project would be less than 100,000 square feet and its trip generation characteristics would be similar to local-serving retail. Based on data provided by the project applicant, approximately 80% of the student population would reside within 5-miles of the project site. The Governor’s Office of Planning and Research (OPR) Technical Advisory dated December 2018 states that “By adding retail opportunities into the urban fabric and thereby improving retail destination proximity, localserving retail development tends to shorten trips and reduce VMT. Thus, lead agencies generally may presume such development creates a less-than-significant transportation impact.” School uses are similar to retail uses, in that, the more schools that are located within in a given area, the shorter the student trips between the school and other complementary land uses (such as employment or residential uses). Student trips to and from schools are analogous to customer trips to and from retail uses. Both land uses (retail and schools) are supported by growth in employment and housing, which are the main drivers of trip-making activity. Thus, applying the same reasoning OPR uses for retail projects, the proposed school could be screened-out based on the local-serving criteria. A similar finding was reached by the City of Milpitas for the proposed Stratford School located at 125 North Milpitas Boulevard, which was screened using local serving criteria. However, the supporting analysis for this finding was prepared in April of 2021, which pre-dates the adoption of the City’s formal VMT policy. Although there is reasonable evidence to support a finding that the project could be screened out based on current City policy, a detailed analysis of the VMT generated by the project was prepared to confirm this finding.
Prior Approvals
The Milpitas Metro Specific Plan Project (MMSP) supplemental Environmental Impact Report (SEIR) was prepared in April, 2022. The MMSP is a long-term planning document that updates the original 2008 Milpitas Transit Area Specific Plan (TASP) and vision for the area. The changes between the TASP and MMSP included:
1. Expansion of the original 437-acre TASP Plan Area by approximately 73 additional acres, for a total of 510 acres, in order to facilitate the development of an Innovation District east of the Milpitas Transit Center and to promote opportunities for housing development along South Main Street. In addition, the Metro Plan redefines the five Districts, such that they are
1323 Great Mall Drive – Transportation CEQA Analysis May 28, 2024 Page | 4
bounded by major streets and include a mix of land uses, development densities, parks, street grids, and pedestrian connections.
2. Changes to the land use classifications and policies.
3. Additional residential and non-residential density, and related population and employment growth.
4. Extension of the Metro Plan horizon year by 10 years (from 2030 to 2040), compared to the TASP.
The current zoning for the project site is C2 Commercial, which will be updated with the adoption of the Phase 1 Zoning Code update to establish BPRD Zoning Districts. The proposed project is located within the MMSP area and its land use designation is BPRD-R (Business Park R&D, Limited Residential). This land use classification supports research and development activities, offices, high tech, hotels, retail services, and education uses.
The proposed educational use was contemplated as a potential development on the project site in the MMSP and therefore its CEQA impacts have been addressed in the MMSP EIR which was prepared as a supplemental EIR to the TASP. Although the Metro Plan would result in an increase in VMT compared to the TASP because of more intensive development, the MMSP draft SEIR concluded that the Metro Plan (2040 Cumulative Plus Project) scenario is estimated to substantially lower VMT per service population, per capita, and per employee relative to both the 2040 Santa Clara countywide average and the Milpitas 2040 General Plan (2040 Cumulative No Project) scenario.
Individual projects consistent with the MMSP may qualify for a statutory exemption under CEQA.
Once consistency is determined, no additional CEQA review is required though projects will still need to be reviewed by the City’s Engineering and Planning Departments for non-CEQA related site-specific measures.
The MMSP envisions continued investments in essential infrastructure, including mobility/transportation to serve new development. Investments in new infrastructure and improvements expected to serve the MMSP are expected to be primarily funded through:
1. The Transit Area Development Impact Fee (TADIF) – The TADIF will continue to be levied upon new development within the MMSP area to ensure that new development pays its appropriate and proportionate share of new infrastructure and other improvements.
2. Citywide Fees/Exactions – New and existing infrastructure investments will serve new development in both the Milpitas Metro Specific Plan and other areas of the city. This could include new public safety facilities. A portion of the new funding for these improvements will likely come from other city funding sources, including fees on new development outside of the Milpitas Metro Specific Plan.
3. Grants – The City has successfully pursued grant funding for a range of improvements since TASP adoption. Grant funding helps cover potions of new public infrastructure and improvement costs that cannot be allocated to new development.
The Milpitas Metro Specific Plan requires all new development projects to implement a travel demand management program (TDM), with a goal of reducing VMT by 15 percent or more below the regional baseline per employee or per resident and efficiently provide parking that meets the needs of employees and visitors. TDM is typically categorized as a set of strategies aimed at
1323 Great Mall Drive – Transportation CEQA Analysis May 28, 2024 Page | 5
encouraging transit use, walking, biking, and carpooling while reducing single occupant vehicle trips, vehicle miles traveled, and parking demand. Possible TDM measures for the proposed project include:
• Marketing/education
• Provision of bicycle parking spaces
• Fully subsidized transit passes (e. g. VTA, BART, Caltrain). At a minimum the transit subsidy should be equivalent to the cost of a monthly VTA pass
• Carpooling
Although the project use was previously included in the MMSP and prior CEQA documentation, this report includes a detailed analysis of Vehicle Miles Travelled (VMT) to ensure the project would not create additional impacts over and above what has previously been identified.
Detailed VMT Analysis
The detailed VMT analysis must consider the trip-making activity of the employment component of the project (school staff), the students, as well as the VMT generated by the existing office use it would replace. This is described in the following sections.
School Employee VMT Analysis
Because school employees would have similar trip-making characteristics (origin/destination and length of trips) as typical office employees, the total employee VMT for the existing office building was compared to the total employee VMT for the proposed Stratford school (see Table 1). Valley Transportation Authority (VTA) Travel Demand Forecast (TDF) model assumptions were used to estimate the number of employees that could be expected to occupy the existing vacant office use.
The conversion rate from office square footage to employees was 3.3 jobs per 1,000 square feet.
Thus, for an office building size of 51,740 square feet, approximately 170 employees could be expected. Based on the Santa Clara County VMT Estimation Tool, the VMT per employee for the zone within which the project is located would be 15.5. The total employee VMT for the existing office building would therefore be 2,635 (170 x 15.5). The proposed school is expected to have a maximum of 75 employees on any given day. Using a VMT per employee of 15.5, the proposed project would generate a total employee VMT of 1,163 (75 x 15.5), which would be less than the total employee VMT for the existing office building. Thus, the proposed project would result in a decrease in the total employee VMT from the site.

Table 1
Employee VMT Analysis
Student VMT Analysis
For common land uses such as residential, employment, and retail, quantitative methods are frequently used to determine VMT. However, for unique land uses for which models are not readily available, such as private schools, OPR guidelines allow for qualitative analysis of VMT impacts.
This section evaluates, qualitatively, whether the proposed school would increase the travel distances of students, given the relative location of complementary land uses and other Stratford schools in the area.
There are currently three Stratford schools in Milpitas. These lower division schools are all located less than 3 miles from the proposed Stratford high school, including:
• 341 Great Mall Parkway - grades pre-kindergarten to 8th • 25 Corning Avenue - grades kindergarten to 5th
• 125 N Milpitas Boulevard - grades preschool to 2nd
Based on the analysis of student zip code data provided by Stratford for students currently enrolled in all of the Milpitas Stratford Schools (Pre-K to 8th grade, 1410 students including siblings), 80% of the students reside within a 5-mile distance and 92% of the students reside within a 10-mile distance from the proposed school. There is currently only one Stratford high school in the south bay region, and it is located at 3800 Blackford Avenue in San Jose. Thus, in the absence of the proposed Stratford High School in Milpitas, to continue their high school education at Stratford School, Milpitas Stratford students would attend the San Jose Blackford Avenue campus, that is located 11 to 15 miles from the proposed high school at 1323 Great Mall Drive. Stratford anticipates that the student population for the proposed high school at full enrollment will resemble the demographics of all pre-school to 8th grade students at the existing Milpitas campuses. By providing a high school in Milpitas in close proximity to the existing lower division Stratford schools, the project would shorten trips and reduce VMT by providing an opportunity for students to attend high school locally, instead of travelling to the neighborhood city. The proposed project would also result in shorter travel distances for students coming from Alum Rock and Fremont, which are all located within a 5-to-10-mile radius of the proposed project. Thus, lower grade students from these communities who wish to continue high school with Stratford would have shorter travel distances to the proposed high school at 1323 Great Mall Parkway compared to travelling to the San Jose Blackford Avenue campus. Furthermore, the project would be located in close proximity to the # of

Milpitas Transit Center, which provides access to BART, light rail, and several bus routes. Given that the project would primarily serve older, high school-age students, the proximity of these facilities would increase the probability of transit trips to and from the project site, further reducing VMT. Last, as previously mentioned, school uses are similar to retail uses, in that, the more private schools that are located in a given area, the shorter the student trips between the school and other complementary land uses (such as employment or residential uses). Schools are primarily supporting uses for residential and employment uses, which are the main drivers of trip-making activity. Thus, by providing additional private schools in accessible and centralized locations, the private school student VMT per capita could be expected to decrease.
VMT Conclusions
The proposed project meets two of the criteria outlined in the City VMT guidelines for project screening. First, the project would constitute a local serving use, as it would primarily serve the surrounding residents, act as a feeder school for existing Stratford schools within the City, and would be less than 100,000 square feet. This is consistent with a prior finding from the City that the Stratford Schol at 125 North Milpitas Boulevard was determined to be local serving. Second, the project is consistent with the approved land use for the site identified in the MMSP, which includes educational uses and was cleared environmentally by the City’s MMSP SEIR. The transportation impacts of the MMSP have already been identified and mitigated to the extent feasible. The project would be required to implement a TDM program and other types of fees adopted by the City.
Therefore, given the City’s screening criteria, prior finding regarding private school projects, and that the use for the site is already cleared environmentally, the impacts of the project on VMT are considered less than significant.
Because the City guidelines state that school projects may require detailed analysis of VMT impacts, further analysis was conducted to confirm the results of the VMT screening assessment.
The VMT impacts of the proposed project were evaluated in terms of its effects on staff and student VMT. For staff, the employment VMT from the site would be reduced by approximately 1,473 vehicle-miles per day relative to the existing use. For students, the proposed project would provide an alternate location for Stratford school students to continue their education without traveling to a more distant location, thus reducing VMT per capita at Stratford schools. This effect is similar to what occurs when local-serving retail projects are constructed, which are presumed to have a less than significant impact on VMT. Thus, the detailed VMT analysis supports the finding that project’s overall impact to VMT is considered less than significant.
Pedestrians, Bicycles and Transit
Pedestrian Facilities
Sidewalks are provided on most of the roadways surrounding the project site. There are existing sidewalks on the east side of Great Mall Parkway, both sides of Mustang Drive, south side of Great Mall Drive, east side of Falcon Drive and the north side of Montague Expressway. The signalized intersections at Great Mall Parkway/Mustang Drive and Great Mall Parkway/Montague Expressway provide crosswalks, curb ramps, and pedestrian-actuated pedestrian-crossing phases on all approaches. The unsignalized intersections surrounding the project site have a marked crosswalk on at least one of the approaches. There is also an existing pedestrian pathway that runs parallel to and south of Mustang Drive along the northwestern boundary of the project site connecting Great Mall Parkway to Great Mall Drive. Although there is no existing sidewalk on the west side of Falcon Drive, there would be direct pedestrian connections between the project site and the nearby BART/LRT stations. The project would install a pedestrian/bike gate that would provide a direct link
1323 Great Mall Drive – Transportation CEQA Analysis May 28, 2024 Page | 8
for students to access the sidewalk along Great Mall Parkway, adjacent to the new artificial turf field, between the proposed school and the existing school to the south. Pedestrians and cyclists to/from the Great Mall/Main LRT station could access the project site via the existing sidewalk along the east side of Great Mall Parkway and the pedestrian bridge near South Main Street.
Alternatively, they could access the South Milpitas LRT station via sidewalks on Great Mall Parkway and the at-grade signalized pedestrian crossing at South Milpitas Boulevard. Pedestrians and cyclists to/from the Milpitas BART station could access the project site via either the pedestrian bridge at Piper Drive and the sidewalk along the north side of Montague Expressway or use the signalized crosswalk across Montague Expressway at Great Mall Parkway. The preferred route to/from the BART station would be to use the pedestrian bridge near Piper Drive, as it would not require students to cross the busy signalized intersection of Great Mall Drive/Montague Expressway.
Recommendation: The school should provide educational material to students and staff on safe routes to/from the LRT and BART stations, discouraging them from using the drive aisles of the existing school to the south and from jaywalking across Falcon Drive.
It is anticipated that the volume of pedestrians generated by the project would not exceed the carrying capacity of the existing sidewalks and crosswalks on streets surrounding the site. The project would not remove any pedestrian facilities, nor would it conflict with the City of Milpitas Trail, Pedestrian and Bicycle Master Plan. Accordingly, the project would have no significant impact on pedestrian facilities.
Bicycle Facilities
Near the project site, Class II bike lanes are located on both sides along Great Mall Parkway, McCandless Drive, and on South Milpitas Boulevard. The project would provide a total of 96 onsite bicycle parking spaces between the proposed project site and the existing Stratford school to the south, so that they can be used by students and staff of both schools. It is anticipated that the volume of cyclists generated by the project would not exceed the carrying capacity of the existing bike facilities surrounding the site. In addition, the project would not remove any bicycle facilities, nor would it conflict with the City’s Trail, Pedestrian and Bicycle Master Plan. Thus, the project would have no significant impact on bicycle facilities.
Transit Facilities
The project would be located in close proximity to the Milpitas Transit Center, which provides access to BART, light rail, and several bus routes. Given that the project would primarily serve older, high school-age students, the project would generate some transit trips made by students and staff. However, the volume of transit trips generated by the project is not expected to exceed the carrying capacity of the existing transit services to the site. The project, by itself, would not require additional transit service to the area or improvements to existing transit service frequencies.
Nor would the project preclude, modify, or otherwise affect existing or proposed transit projects or policies identified by the Valley Transportation Authority (VTA). Therefore, the proposed project would not create an adverse impact to transit services in the area.
Emergency Access
The proposed project would not reroute or change any of the City streets in its vicinity that would impact emergency vehicle access to properties in the area. In addition, the proposed project would maintain the site’s existing driveways, which would accommodate emergency vehicles. Thus, the project would not result in a significant impact to emergency vehicle access.
