Subject
Consideration of (i) an Architectural and Site Approval permit, (ii) adoption of a Notice of
Exempt Surplus Land Act Declaration, and (iii) a Disposition and Development Agreement by
and between the City of Cupertino, a municipal corporation and Mary Avenu e, L.P., a California
limited partnership in connection with the development of a 40 -unit below market rate
development (Mary Avenue Villas Project) on a Housing Element Site, of which 19 units are
dedicated to the Intellectually Developmentally Disabled a nd 21 units reserved for extremely
low, very low, and low income residents of the community, located on public property.
(Application No(s): ASA-2025-006; Applicant(s): Charities Housing; Location: (APN: 326-27-053,
Mary Avenue Right-of-Way).
Recommended Action
1. Find the project exempt from the California Environmental Quality Act (CEQA)
2. Adopt Resolution No. 26-___ approving Architectural & Site Approval Permit (ASA-2025-
006) (Attachment A);
3. Adopt Resolution No. 26-___ declaring the Property Exempt Surplus Land pursuant to the
Surplus Land Act (Attachment B)
4. Adopt Resolution No. 26-___ approving the Disposition and Development Agreement
(Attachment C)
Staff’s responses to questions received from councilmember are shown in italics.
Q1: Mary Ave project would be below-market-rate for only 55 years. But the city donated the land
and some funding. What happens after 55 years? Who profits from the full market value?
Staff response: The Mary Ave project will be restricted for a term of 99 years per the latest negotiations. A
99 year restriction is also known as “as good as forever” since this typically outlasts the lifetime of the
building. After 99 years, the City would have the ability to either re-acquire the property at a significantly
discounted rate (for the current fair-market-value of the capital improvements, excluding the value of the
land), negotiate the extension of affordability covenants with an additional contribution, typically to
rehabilitate units, in order to ensure continued affordability of the project, or simply walk -away from the
land and project.
Q2: What happens to the tenants in 55 years? Say, someone moved in when they are 20 years old
now. In 55 years, when they are 75 years old, they would be kicked out since the units would
become market rate?
Staff response: Upon affordability covenants nearing expiration after 99 years, the City would have the
opportunity to either re-acquire the project or negotiate for extensions as mentioned above. Should the City
not exercise either option, the developer would be required to do required noticing to the tenant in 3 year,
12 month, and 6 month notifications as deemed necessary by state law under Government Code Section
65863.10. At 12 months prior to restriction expiration, tenants would also be given the opt ion to reapply
to the City of Cupertino BMR program to be rehoused with priority replacement due to the latest BMR
Anti-Displacement policy passed by City Council (Resolution 25-0051). Should they remain in those units
until final expiration, they would not be immediately evicted, but they would be presented with rental rates
comparable to market-rate units. The City continues to explore more tenant protections policies and anti -
displacement programs for low-income households through the Housing Commission to be brought to the
City Council for consideration.
Q3 I heard that some cities have been able to have forever BMR housing. Why is it not possible
for Mary Ave project?
Staff response: The City of Cupertino, and other cities, have been able to approve 99 year restrictions (also
known as “as good as forever” BMR housing) through inclusionary units within market-rate developments
as the rent collected on the market-rate units essentially subsidize the affordable units in the same project.
Furthermore, because they do not use public subsidies, they do not have to consider requirements regarding
repayment of loans as part of being awarded tax credit financing. Thus, it is more challenging for the Mary
Ave project, which is a 100% affordable project. However, the City was able to achieve restricting the units
for a term of 99 years during the latest negotiations.
Q4: What exactly would be reconfiguration of the Mary Avenue? Please provide clear images for
before and after.
Staff response: The Plan Set provided with the Staff Report (Attachemnt F) showed the existing conditions
as well as the proposed layout of the Mary Avenue Right-of-Way. Supplemental Attachment G shows sheets
C000.0 (Existing Conditions and Demolition Plan), C001.0 (Preliminary Site Plan), and C005.0
(Sections), which had been included in the Plan Set that had been provided with the Staff Report.
Q5: What exactly are the existing parking spots and what exactly are the new ones? Please provide
clear images for before and after.
Staff response: Please refer to the answer for Q4.
Q6: What exactly would be vacated from the Public Right of Ways? There was no map included
in this agenda and no map of the Public Right of Ways on to be vacated the 1/27 Planning
Commission agenda. It's unclear what exactly is the dimension of the Public Right of Way to be
vacated.
Staff response: Sheet C000.0 shows the property line of the parcel to be vacated (Supplemental Attachment
G). Further, Supplemental Attachment H (Parcel Map) shows a clean dimensioned parcel without the
proposed development and/or existing conditions overlaying onto the sheet.
Q7: Can the City approve this agenda item without vacating the Public Right of Ways first?
Staff response: Yes. The City may approve the Disposition and Development Agreement (DDA) before the
public right-of-way is vacated. The public right-of-way must be vacated before the title to the property is
actually transferred to the developer, but that transfer does n ot happen when the DDA is approved. The
transfer occurs later, at the project’s “closing,” which takes place after the developer has secured financing
and met other requirements. The DDA specifically requires that the right-of-way be vacated before closing
can occur. Closing is currently estimated to occur around January 2027.
Q8: The agenda packet does not include the traffic analysis. Could you include those?
Staff response: Please refer to Attachment I, Transportation Study for Proposed Affordable Housing
Project on Mary Avenue in Cupertino, California, dated November 13, 2025.
Q9: The agenda packet does not include fiscal impact analysis. Could you include those?
Staff response: A fiscal impact analysis is only required if converting office and/or commercial uses to
residential or residential mixed-use (General Plan Strategy LU-8.2.1.) As this is not currently an office or
commercial development, a fiscal impact analysis was not required.
Q10: What's the criteria for applicants to get a unit in the BMR and the IDD units? Who decides
them? Can we prioritize long-time Cupertino residents so that people who grew up in Cupertino
get the priority, for example?
Staff response: The Distribution and Development Agreement requires that the City’s BMR waitlist for
the BMR units be used, allowing the City to centralize the application process while also using the City’s
current priorities for lease-up, including Cupertino displaced rental tenants, Cupertino residents, and
Cupertino workers getting higher priority for placement. In order to use this method however, the lease up
priorities of Mary Ave must match the priorities of the City BMR waitlist to prevent the need to keep a
waitlist just for the Mary Ave. project, so we will not be able to specifically prioritize “people who grew up
in Cupertino”. For the IDD units, a special referral will be needed through non-profit organizations such
as Housing Choices who work with individuals with disabilities. Once referred the City’s BMR
administrator would conduct a separate lottery utilizing the City’s preference system of Cupertino
displaced rental tenants, Cupertino residents, and Cupertino workers. In short, we can implement a
Cupertino preference policy, and it would need to match the preference policy of the BMR waitlist.
Q11. How many IDD units at the Mary Avenue Project will be reserved for Intellectually or
Developmentally Disabled (IDD) residents?
The Disposition and Development Agreement (DDA) provides that 19 of the units will be reserved for IDD
residents.
Q12. Can the City adopt the DDA before the Planning Commission finds that vacation of the
right-of-way and the disposition of City property are consistent with the General Plan?
Yes, the City may adopt the DDA before the Planning Commission finds that the vacation of the right -of-
way and the disposition of City property are consistent with the General Plan because the DDA is
contingent upon the Planning Commission finding that bot h the vacation of the right-of-way and the
disposition of City property are consistent with the General Plan. In other words, that determination is
required to occur prior to the closing of the transaction. By adopting the DDA now, the City and the
Developer are not closing the transaction. Rather the DDA provides a roadmap with numerous items that
must occur before the deal is finalized. The actual closing, including recording the vacation of the right-of-
way or transferring the City property, cannot occu r unless the Planning Commission finds that the
vacation of the right-of-way and the disposition of the City property are consistent with the general plan.
We will bring those items to the Planning Commission later this month once the DDA is executed.
Q13. Shouldn’t the term of the affordability covenants be 99 years?
Yes. We will be recommending Council adopt the DDA with direction to extend the term of the affordability
covenants to 99 years, and to extend the date when the City may re-acquire the project to 99 years to track
the date the affordability covenants expire.

I. Transportation Study for Proposed Affordable Housing Project on Mary Avenue in Cupertino,
California, dated November 13, 2025.
Memorandum
Date: November 13, 2025
To: Mr. Andy Lief, Charities Housing
From: Kai-Ling Kuo, Andrea Lin
Subject: Transportation Study for Proposed Affordable Housing Project on Mary Avenue in
Cupertino, California
Hexagon Transportation Consultants, Inc. has completed a transportation study for the proposed
affordable housing project on Mary Avenue in Cupertino, California. The project proposes affordable
housing between the SR 85 soundwall and Mary Avenue. The project proposes constructing 2 two-
story buildings with a total of 40 dwelling units (19 affordable disabled housing units and 21 affordable
housing units) and 20 on-site parking spaces (18 regular spaces and 2 accessible spaces) on a 0.8-
acre site. Access to the buildings would be provided via 2 two-way driveways on Mary Avenue. The
project site location and site plan are shown in Figure 1 and Figure 2, respectively.
Scope of Study
This study was conducted for the purpose of identifying the potential transportation impacts and
operational issues related to the proposed development. The transportation impacts of the project
were evaluated following the standards and methodologies established in the City of Cupertino’s
Transportation Study (TS) Guidelines (January 2025). This study consists of a California
Environmental Quality Act (CEQA) vehicle miles traveled (VMT) analysis and a transportation
analysis per the TS Guidelines.
As discussed below, the project would result in an increase in net vehicle trip generation of 163 daily
trips, which is within the definition of a Tier 2 project (projects with trip generation between 110 and
1,000 daily vehicle trips and less than 100 peak hour trips). Based on the City’s TS Guidelines, a Tier
2 transportation analysis requires an off-site intersection operations analysis, review of General Plan
consistency, a parking supply evaluation, a site access and circulation assessment, and a safety
assessment. The intersection operations analysis includes an analysis of weekday AM and PM peak-
hour traffic conditions at the intersection of Mary Avenue and Stevens Creek Boulevard.
VMT Analysis
Transportation impacts under CEQA are measured using VMT. The City of Cupertino TS Guidelines
provide VMT exemption screening criteria for development projects. If a project meets the City’s
screening criteria, the project is expected to result in a less-than-significant VMT impact and a
detailed CEQA VMT analysis is not required.

Per the TS Guidelines, a project may be screened out if it meets one or more of the following criteria:
(1) a project located within one-quarter mile of a High-Quality Transit Corridor or transit stop as
defined by CEQA; (2) local-serving retail of 50,000 square feet or less; or (3) land-use projects
consisting of 100% affordable housing. The project would provide 100% affordable housing; thus, it is
expected to result in a less-than-significant VMT impact and would not require detailed VMT analysis.
Existing Transportation System
The existing transportation system in the project study area is described below. Included are
descriptions of the existing roadway network, pedestrian and bicycle facilities, and transit services.
Existing Roadway Network
Regional access to the project site is provided via SR 85. Local access to the site is provided via
Stevens Creek Boulevard, Stelling Road, and Mary Avenue. These facilities are described below.
SR 85 is a six-lane freeway with two mixed-flow lanes and one high-occupancy vehicle (HOV) lane in
each direction in the vicinity of the project site. SR 85 extends north through Mountain View,
connecting with US 101, and south through San Jose, connecting again with US 101. Access to the
project site is provided via its interchange with Stevens Creek Boulevard.
Stevens Creek Boulevard is an east-west roadway classified as a boulevard (arterial) in the City’s
General Plan. It extends from Ridgeway Drive in the west to Bascom Avenue in the east. In the
vicinity of the project site, Stevens Creek Boulevard has 6 lanes with left turn/U-turn pockets at
intersections, a landscaped median, buffered bike lanes in each direction, and sidewalks along both
sides of the roadway. On-street parking is prohibited on both sides of the roadway, and the posted
speed limit is 35 miles per hour (mph). Access to the project site is provided via its intersection with
Mary Avenue/Campus Drive.
Stelling Road is a north-south roadway classified as an avenue (major collector) in the City’s
General Plan. It extends past Homestead Road in the north and past Prospect Road to the south. In
the vicinity of the project site, Stelling Road has 4 lanes with left turn/U-turn pockets at intersections,
a landscaped median, sidewalks along both sides of the roadway, and striped bike lanes in each
direction. On-street parking is prohibited on both sides of the street. The posted speed limit is 35
mph. Access to the project site is provided via its intersection with Stevens Creek Boulevard.
Mary Avenue is a two-lane north-south local street classified as a neighborhood connector in the
City’s General Plan. It extends from Meteor Drive in the north to Campus Drive in the south. Mary
Avenue has sidewalks on the east side of the street and on the west side of the street for the most
part, except along the project frontage. It has buffered and protected (Class IV) bike lanes on both
sides of the roadway. On-street parking is allowed on both sides of the street north of Morro Bay
Terrace. The parking is diagonal on the west side and parallel on the east side. The project would
remove parking on the east side and change the west side to parallel parking. The posted speed limit
is 30 mph. Mary Avenue provides direct access to the project site.
Existing Transit Services
Existing transit service to the City of Cupertino is provided by the Santa Clara Valley Transportation
Authority (VTA). The VTA bus routes in the project vicinity and the bus stops near the project site are
summarized in Table 1 and shown in Figure 3.
The closest bus stop is located about 2,100 feet away near the intersection of Mary Avenue and
Stevens Creek Boulevard. The nearby bus stop located at De Anza College is about 2,600 feet from
the project site. The bus stops on Stevens Creek Boulevard at Stelling Road are more than a half
mile from the project site.

Existing Transit Services
Existing Bicycle Facilities
The bicycle facilities that exist in the project vicinity (see Figure 4) include bike lanes and bike routes.
Bike lanes are lanes on roadways designated for use by bicycles with special lane markings,
pavement legends, and signage. Bike routes are signed bike routes where bicyclists share a travel
lane with motorists.
Bike lanes are present on Mary Avenue (Class IV parking-protected on a portion of the west side
between Lubec Street and Morro Bay Terrace and on a portion of the east side between the north
end of Mary Avenue Dog Park and the Cupertino Memorial Park parking lot entrance, and Class IIB
buffered lanes on the rest of the street), Stevens Creek Boulevard (Class II), Bubb Road (Class IV),
and Stelling Road (Class II). A bike route in the area connects the project to local schools like Garden
Gate Elementary school. In the project vicinity, the route is present along Lubec Street (east of Mary
Avenue), Anson Avenue (north of Lubec Street) Milford Drive, Castine Avenue (north of Milford Drive)
and Greenleaf Drive.
Existing Pedestrian Facilities
Pedestrian facilities consist of sidewalks, ADA compliant curb ramps, and crosswalks at many of the
nearby intersections. In the vicinity of the project site, continuous sidewalks exist along the east side
of Mary Avenue and both sides of Stevens Creek Boulevard, Campus Drive, and Stelling Road.
There is no sidewalk on the west side of Mary Avenue along the project frontage and the Dog Park.
There are two high-visibility crosswalks across Mary Avenue at unsignalized intersections along the
street: one at Lubec Street north of the site and the other at the driveway for the Cupertino Memorial
Park parking lot, south of the site, with rapid rectangular flashing beacons (RRFB). At the signalized
intersection of Mary Avenue and Stevens Creek Boulevard, high-visibility crosswalks are provided
across the north, south, east and west legs of the intersection.

Project Trip Estimates
The magnitude of traffic produced by a new development and the locations where that traffic would
appear were estimated using a three-step process: (1) trip generation, (2) trip distribution, and (3) trip
assignment. In determining project trip generation, the magnitude of traffic traveling to and from the
proposed residential development was estimated for the AM and PM peak hours. As part of the
project trip distribution and assignment, directions to and from which the project trips would travel
were estimated and project trips generated were assigned to specific streets and intersections. These
procedures are described below:
Trip Generation
Through empirical research, data have been collected that show trip generation rates for many types
of land uses. The data are published in the Institute of Transportation Engineers’ (ITE) Trip
Generation Manual, 12th Edition. ITE does not have a category for developmentally disabled
housing. The closest category for estimating trips generated by this land use is “Senior Adult
Housing” as most residents of the project would likely not own cars and care takers or assistants
would generate most of the trips. Using this category to represent the developmentally disabled
housing units is likely a slight over-estimate of generated traffic because residents would not have
cars.
Thus, trips that would be generated by the project were estimated using the ITE average trip rates for
“Senior Adult Housing - Multifamily” (ITE Land Use 252) for the developmentally disabled units and
“Affordable Housing” (ITE Land Use 223) for the proposed affordable housing units.
The proposed project is estimated to generate 163 daily vehicle trips, with 12 trips (3 inbound and 9
outbound) during the AM peak hour and 15 trips (9 inbound and 6 outbound) during the PM peak
hour (see Table 2).
Table 2
Project Trip Generation Estimates
Trip Distribution and Assignment
The trip distribution pattern for the project was estimated based on the existing travel patterns on the
surrounding roadway network and the locations of complementary land uses. The peak-hour trips
generated by the project were assigned to the roadway system based on the trip distribution pattern,
directions of approach and departure, and the roadway network connections. Project trip distribution
and trip assignment are shown in Figure 5. For a conservative analysis, it is assumed that all trips
from the project site would pass through the study intersection at Mary Avenue and Stevens Creek
Boulevard.

Intersection Traffic Operations
This section presents the methods used to determine traffic conditions at the study intersection and
the traffic effects of the project.
Scope of Analysis
This study analyzes the traffic effects of the project at the Mary Avenue/Campus Drive and Stevens
Creek Boulevard intersection during the weekday AM and PM peak hours of commute traffic. Traffic
conditions at the study location were analyzed for the weekday AM (7:00 AM to 9:00 AM) and PM
(4:00 PM to 6:00 PM) peak hours of commute traffic. These periods represent the most congested
traffic conditions on the surrounding street network during a typical weekday.
Intersection traffic conditions were evaluated for the following scenarios:
• Existing Conditions. Existing AM and PM peak-hour traffic volumes were obtained from new
turning movement counts conducted on a typical weekday, October 7, 2025 (see Appendix A).
• Existing Plus Project Conditions. Existing plus project traffic volumes were estimated by
adding to the existing traffic volumes the additional traffic generated by the project (see Figure
5). Existing plus project conditions were evaluated relative to existing conditions to determine
potential project adverse effects.
Intersection Level of Service Analysis Methodology
Traffic conditions at the study intersection were evaluated using level of service (LOS). Level of
service is a qualitative description of operating conditions ranging from LOS A, or free-flow conditions
with little or no delay, to LOS F, or jammed conditions with excessive delays.
The City of Cupertino evaluates level of service at signalized intersections based on the latest
Highway Capacity Manual (HCM) level of service methodology. For the study, the intersection levels
of service were analyzed using Synchro software in accordance with the HCM 7th Edition
methodology. The HCM method evaluates signalized intersection operations based on average
control delay time for all vehicles at an intersection. The correlation between average control delay
and level of service is shown in Table 3.
Signalized study intersections are typically subject to the local municipalities’ level of service
standards. The City’s TS Guidelines (2025) do not provide level of service standards for signalized
intersections. For this study, an LOS D standard was applied to the study intersection based on the
2021 TS Guidelines.
Definition of Adverse Intersection Operational Effects
For most major intersections, a development is said to create an adverse effect on traffic conditions at
a study intersection if for either hour, any of the following conditions occur:
1. The level of service at signalized intersections degrades from an acceptable level (LOS D or
better) under no-project conditions to an unacceptable LOS E or F under project conditions.
2. The project would deteriorate already unacceptable operations at a signalized intersection by
increasing the average critical delay by four or more seconds and increasing the critical
volume-to-capacity (v/c) ratio by 0.01 or more; or increase the v/c ratio by 0.01 or more at an
intersection with unacceptable operations when the change in critical delay is negative (i.e.
decreases). This can occur if the critical movements change.

P a g e | 1 1
Table 3
Signalized Intersection Level of Service Definitions Based on Average Control Delay
The 2025 TS Guidelines also provide a deficiency criterion for intersection vehicle queuing as part of
evaluating the project’s effect on traffic operations. An adverse effect on signalized intersection
operations would occur if for either peak hour:
1. The project traffic would cause 95th percentile vehicle queues to exceed the existing or
planned length of a turn pocket, or
2. Where a queue exceeds the available storage without the project, project traffic would
increase the queue by more than 50 feet.
Lane Configurations and Traffic Volumes
The existing lane configurations at the study intersections are shown on Figure 6.
The traffic volumes for the existing conditions and existing plus project conditions are shown in Figure
6 and described above for the analysis scenarios.

Intersection Levels of Service
The results of the intersection level of service analysis (see Table 4) show that the study intersection
would operate at an acceptable level of service under existing and existing plus project conditions.
The intersection level of service calculation report is included in Appendix B.
Table 4
Intersection Level of Service Summary
Intersection Queuing Analysis
Typically, vehicle queuing analysis is done for high-demand movements at intersections where the
project would add a substantial number of trips to the left-turn movements (10 or more peak hour
vehicle trips per lane). The project would not be adding 10 or more peak hour vehicle trips per lane to
any turning movement (see Figure 5). Thus, it is not expected that the addition of the project would
negatively affect the existing queuing conditions.
General Plan Consistency
The project is located on Mary Avenue, which is a local street. This street is not identified on the
City’s High Injury Network. The project would not conflict with the General Plan policies because the
project would not affect access to roadways, transit, bicycle, or pedestrian facilities.
Pedestrian Facilities
The existing pedestrian facilities in the project vicinity provide good connectivity with continuous
sidewalks from the project site to nearby points of interest, including bus stops, schools, and parks.
High-visibility crosswalks across Mary Avenue are provided at the unsignalized intersections at Lubec
Street to the north and at Cupertino Memorial Park driveway to the south.
There is currently no sidewalk along the project frontage. The project would construct a new 4.5-foot-
wide sidewalk along its frontage on Mary Avenue to connect to the existing sidewalk to the south and
the dog park to the north. The new sidewalk is consistent with the existing sidewalk configuration
within the adjacent neighborhood. The sidewalk would be buffered from traffic by a 5-foot-wide bike
lane, 2.5-foot buffer, and parallel street parking. Walkways from the street frontage would provide
direct access to the buildings.
The project would not affect the existing pedestrian access in the area. The project would provide
adequate pedestrian facilities on site connecting pedestrians to the rest of the City’s pedestrian
facilities.
Bicycle Facilities
The project proposes re-aligning the existing bike lane along the project frontage and converting the
angled street-parking spaces to parallel street-parking spaces. The proposed bike lane would be 5
feet wide, which meets the minimum recommendation of 5 feet for lateral clearance of bike lanes
listed in the VTA bicycle technical guidelines. The bike lane would be protected from vehicular traffic
by 8-foot-wide parallel parking spaces and a 2.5 foot striped buffer between the bike lane and the

parking spaces. The project would introduce two driveways along the west side of Mary Avenue that
would cross the bike lane. The project proposes using a different paving material to signal to drivers
to slow down and look out for cyclists and pedestrians. The landscaping planters and curb islands
next to the driveways would also provide adequate line of sights for cyclists and pedestrians.
The project proposes two pairs of reverse curves to create a lateral shift of the bike lane at the north
and south ends of the project site to connect the proposed bike lane to the existing bike lane. The
National Association of City Transportation Officials (NACTO) design guidelines for Bike Transitions,
which are adapted from the Urban Bikeway Design Guide, Third Edition, was used to evaluate the
proposed reverse curves. For an urban street, a design speed of 10 mph could be assumed for
protected bike lanes. For an approach speed of 10 mph, NACTO recommends a minimum edge
radius of 18 feet. At the north end of the site, the curve radii are less than 18 feet, which cannot
accommodate a travel speed of 10 mph. At the south end of the site, the curve radii are greater than
18 feet.
Recommendation: To accommodate a design speed of 10 mph for the bike lane per NACTO’s
guidelines, the turn radii of the reserve curves on the north end of the project site should be a
minimum of 18 feet and signage should be added ahead of the curves to inform cyclists to slow down
to 10 mph.
The proposed bicycle lane would connect to the existing bicycle lane on Mary Avenue; thus the
proposed project would not conflict with any planned facilities identified in the City of Cupertino 2016
Bicycle Transportation Plan.
Transit Services
As previously stated, the closest bus stop serves Local Route 51 and is located about 2,100 feet
away at the intersection of Mary Avenue and Stevens Creek Boulevard. The nearby bus stop for
Frequent Route 23 is located at De Anza College and is about 2,600 feet from the project site. The
bus stops in both directions can be accessed via the existing pedestrian network. Any small increase
in transit trips is expected to be accommodated by the existing transit capacity.
Parking
Vehicle Parking
The City of Cupertino minimum parking requirement for medium density multi-family housing per the
City’s Zoning Code (Table 19.124.040(A)) is two parking spaces per dwelling unit. Because the
project would provide 100% affordable housing, the project can qualify for the State Density Bonus
Law. Per public Resources Code Section 65915(p)(2), the City may not impose minimum vehicular
parking ratios for developments that include at least 20% low-income units that exceed 0.5 spaces
per unit.
Therefore, for the proposed 40 dwelling units, the project would be required to provide 20 parking
spaces per the State Density Bonus Law. Additionally, approximately half of the dwelling units
provided by the project would be for developmentally disabled residents that would not own cars or
drive. The project proposes a total of 20 parking spaces in an on-site parking lot. Thus, the project
meets the State Density Bonus Law parking requirements.
Bicycle Parking
The City’s zoning code requires medium density multi-family developments to provide one long-term
(Class I Facility) bicycle parking space per 2 residential units and one short-term (Class II Facility)
bicycle parking space per 10 residential units. For the proposed 40 units, the project would be
required to provide 20 long-term and 4 short-term bicycle parking spaces. The project proposes 16
inverted-U bike racks (which provide 2 bicycle parking spaces per inverted-U bike rack): 4 bike racks
Mary Avenue Affordable Housing Project TA November 13, 2025
P a g e | 1 5
in front of Building 1 near the community room, 3 bike racks north of Building 1, 1 rack in front of
Building 2 near the manager’s office, 4 bike racks behind Building 1 near the elevators, and 4 bike
racks behind Building 2 near the elevators. The 8 proposed bike racks in front of buildings would
provide 16 short-term parking spaces for public use, which would meet the short-term bicycle parking
requirement. The 8 bike racks behind the buildings near the elevators could provide 16 parking
spaces for residents. However, these spaces are not protected. Thus, the project does not meet the
minimum requirements for long-term bicycle parking spaces.
Recommendation: To meet the city’s requirements, the project should provide 20 long-term bicycle
parking spaces. These long-term bicycle parking spaces should be provided in bicycle lockers (fully
enclosed space accessible only by the owner of the bicycle), restricted access rooms (locked room or
enclosure accessible only to the owners), or enclosed cages (chain link enclosures with a lock).
Removal of On-Street Parking
The project would convert the angled street-parking spaces to parallel street-parking spaces on its
frontage along Mary Avenue and remove the parallel street-parking spaces on the east side of the
street across from the project frontage. This would remove 84 angled street-parking spaces on the
west side and 38 parallel street-parking spaces on the east side (approximately 950 feet) and add 33
parallel parking spaces to the west side of Mary Avenue, which would result in a net loss of 89 street-
parking spaces.
Hexagon previously conducted a parking study (see Appendix C) to identify the current parking
supply and demand of the on-street parking on Mary Avenue between Lubec Street and Stevens
Creek Boulevard. There are currently 171 diagonal parking spaces provided along the west side and
70 parallel parking spaces provided on the east side, for a total of 241 on-street parking spaces. The
parking study found the existing peak parking demand was 37 parking spaces (26 spaces on the
west side of Mary Avenue and 11 spaces on the east side of Mary Avenue) with 7 occupied spaces
along the project frontage.
As stated previously, the project meets the vehicular parking requirements per the State Density
Bonus Law with the proposed parking on site. Additionally, approximately half of the dwelling units
provided by the project would be for developmentally disabled residents that would not own cars or
drive. Therefore, the project is not expected to increase parking demand for on street parking.
With the project, there would be 152 on-street parking spaces (with 33 parallel parking spaces along
the project frontage), which would still provide enough spaces to meet the anticipated parking
demand (37 total spaces and 7 spaces along the project frontage).
Site Access and Circulation
A review of the project site plan was performed to identify the adequacy of site access and on-site
circulation. This review is based on the site plan dated May 9, 2025 (see Figure 2 and Figure 7).
Vehicle access to the site would be provided via two driveways along Mary Avenue.
Driveway Design and Operations
The project proposes two driveways on Mary Avenue: one located opposite Parkwood Drive and the
other about 180 feet south of that driveway. Two driveways are necessary because the project
proposes angled on-site parking. The site is not wide enough to provide 90-degree parking.
Per the City’s Standard Details 1-20, driveway width for commercial/high density residential should be
between 24 and 32 feet. The driveway to the north (near Building 2) would be 24 feet wide and the
driveway to the south (near Building 1) would be 26 feet wide, which meets the City’s requirements
for driveway width.
Mary Avenue Affordable Housing Project TA November 13, 2025
P a g e | 1 6
The project-generated trips that are estimated to access both driveways are 12 trips during the AM
peak hour (3 inbound and 9 outbound) and 15 trips during the PM peak hour (9 inbound and 6
outbound). Due to the low number of AM and PM peak hour project-generated trips, operational
issues related to vehicle queuing or delays, or with potential pedestrian or bicycle traffic would be
minimal at the project driveways.
The distance between the first 90-degree parking stall and the street edge for both of the driveways is
24 feet. Thus, there is enough room for one inbound vehicle to queue in the driveway without
blocking the traffic on Mary Avenue. The maximum number of vehicles that would enter a driveway is
9 inbound vehicles during the PM peak hour, which is equivalent to approximately one vehicle every
6 minutes. Thus, no inbound queuing issues are expected at the project driveways.
Driveway Sight Distance
The project driveways should be free and clear of any obstructions to provide adequate sight
distance, thereby ensuring that exiting vehicles can see pedestrians on the sidewalk and vehicles and
bicycles traveling along Mary Avenue. Any landscaping and signage should be located in such a way
to ensure an unobstructed view for drivers exiting the site and turning onto Mary Avenue. Providing
the appropriate sight distance reduces the likelihood of a collision at a driveway and provides drivers
with the ability to locate sufficient gaps in traffic.
The project proposes trees that would be planted along the Mary Avenue frontage near the
driveways. Per the City’s Standard Details 7-2, the canopies of the trees should be at least 8.5 feet in
height so that they do not impede the view of exiting drivers. If additional frontage improvements,
such as signage or additional landscaping, are proposed, they should be located so that the view of
exiting drivers is not impeded or not exceed 3.5 feet in height, per the City’s Standard Details 7-2.
The minimum acceptable sight distance is considered the Caltrans stopping sight distance. Sight
distance requirements vary depending on roadway speeds. Mary Avenue has a speed limit of 30
mph, so the Caltrans stopping sight distance is 250 feet (based on a design speed of 35 mph).
Accordingly, a driver must be able to see 250 feet along Mary Avenue to stop and avoid a collision.
Based on the site plan and narrow travel lanes on Mary Avenue, on-street parking next to the project
driveways would potentially block the line of sight of exiting drivers (see Figure 8).
Recommendation: To ensure drivers exiting the project driveways have adequate lines of sight, it is
recommended that two parallel parking spaces on the north side of each driveway and one parking
space on the south side of the project driveways be removed. If the driveways are changed to one-
way as recommended below, only the parking spaces next to the outbound driveway (south
driveway) need to be removed. The on-street parking supply would still be adequate with the
reduction of these six parallel parking spaces.

On-Site Circulation and Stall Dimensions
On-site vehicular circulation was reviewed in accordance with generally accepted traffic engineering
standards. The project would provide an on-site surface parking lot (20 parking spaces) with a one-
way aisle. In the parking lot, there would be two 90-degree parking spaces on the north end, two 90-
degree parking spaces on the south end, and 16 angled parking spaces (60 degrees) along the west
side of the parking lot (see Figure 7).
The driveways to access the parking lot would be two-way driveways that are 24 feet wide and 26
feet wide with a 26-foot-wide drive aisle to access the 90-degree parking spaces. The drive aisle to
access the 60-degree angled parking spaces would be a one-way aisle that is 14 feet wide.
Recommendation: For improved circulation, it is recommended that the driveways are one-way, with
the north driveway for inbound only and the south driveway for outbound only.
Per the City of Cupertino’s Zoning Code Table 19.124.040(B), the minimum parking stall dimensions
should be 8.5 feet wide and 18 feet long. Two-way drive aisles to access 90-degree parking spaces
should be a minimum of 22 feet wide. The 90-degree parking spaces on the north and south ends of
the parking lot would be a minimum of 8.5 feet wide and 16 feet long and would be accessed by a
drive aisle that is 26 feet wide. The parking spaces include a 2-foot overhang into the walkway in front
of the spaces, which effectively would provide a 6-foot walkway (sufficient for pedestrians to travel
through). Based on the site plan, the proposed 90-degree parking spaces would meet the City’s
minimum stall dimensions.
Per Table 19.124.040(B), a one-way aisle to access 60-degree angle parking spaces should be a
minimum of 13 feet wide. Based on the proposed parking lot plan, the 60-degree angle parking
spaces would be 8.5 feet wide, 18 feet long, and have a one-way aisle that is 14 feet wide. Thus, the
project’s angled parking spaces would meet the City’s minimum requirements.
Emergency Vehicle Access and Circulation
The City of Cupertino Fire Department requires a minimum driveway width of 20 feet, requires
turnarounds for driveways more than 150 feet in length, and requires a minimum of 13.5 feet of
vertical clearance. The project site has a maximum depth of 42 feet from Mary Avenue. Therefore,
Mary Avenue would serve as the project’s fire access road.
Garbage Truck Access and Circulation
Concrete trash pads/enclosures are shown in the parking lot. All garbage collection activities would
occur on-site. Garbage trucks would need to pull into one of the driveways, perform garbage
collection activities, back out onto Mary Avenue, and pull into the other driveway to perform the rest of
the garbage collection activities. The truck would encroach onto the opposite travel lane when turning
into and out of the driveways. However, because of the relatively low volumes on Mary Avenue, it is
not expected that this would cause any operational issues. Figure 7 shows site access and circulation
for garbage trucks.
Safety Assessment
The project would not alter any streets in the area. The project driveways and the internal aisles on
site are designed in accordance with city standards. The project would generate mostly passenger
vehicles, and the surrounding roadway system is designed to accommodate these vehicles.
Therefore, the project would not worsen existing geometric hazards or create new geometric hazards.

Conclusions
The transportation analysis for the Mary Avenue Affordable Housing Project resulted in the following
conclusions:
• Trip Generation. The proposed project is estimated to generate 163 new daily vehicle trips, with
12 trips (3 inbound and 9 outbound) during the AM peak hour and 15 trips (9 inbound and 6
outbound) during the PM peak hour.
• Intersection Operation. The Mary Avenue and Stevens Creek Boulevard intersection would
operate at an acceptable level of service under existing and existing plus project conditions.
• Site Access and Circulation. The site access and circulation review resulted in the following
recommendations:
o Long-term Bicycle Parking. To meet the city’s requirements, the project should provide 20
long-term bicycle parking spaces. These long-term bicycle parking spaces should be
provided in bicycle lockers (fully enclosed space accessible only by the owner of the
bicycle), restricted access rooms (locked room or enclosure accessible only to the owners,
or enclosed cages (chain link enclosures with a lock).
o Sight Distance. To ensure drivers exiting the project driveways have adequate lines of
sight, it is recommended that two parallel parking spaces on the north side of each
driveway and one parking space on the south side of the project driveways be removed. If
the driveways are changed to one-way as recommended below, only parking spaces next
to the outbound driveway need to be removed.
o Site Circulation. It is recommended that the driveways be one-way access, with the north
driveway for inbound only and the south driveway for outbound only.
o Bike Lane. To accommodate a design speed of 10 mph for the bike lane, the turn radii of
the reserve curves on the north end of the project site should be a minimum of 18 feet and
signage should be added ahead of the curves to inform cyclists to slow down to 10 mph.

Subject: Parking Study and Trip Generation Estimate for the Proposed Affordable Housing
Project on Mary Avenue in Cupertino, California
Hexagon Transportation Consultants, Inc. has completed a parking study and trip generation
estimate for the proposed affordable housing project on Mary Avenue in Cupertino, California. The
project proposes affordable housing between the CA-85 soundwall and Mary Avenue and would
provide 19 units for the developmentally disabled and 21 affordable units. Between Lubec Street
and Stevens Creek Boulevard, 171 diagonal parking spaces are provided along the west side, and
70 parallel parking spaces are provided on the east side of Mary Avenue.
First Parking Counts
Parking counts were completed to determine the current maximum occupied parking spaces on
Mary Avenue between Lubec Street and Stevens Creek Boulevard
Vehicle parking counts were conducted along Mary Avenue on the following dates and times to
determine the parking demand of the existing parking spaces (see Attachment 1). These times
were chosen based on predicted usage of the existing parking spaces from the neighboring park
and other surrounding uses.
• Saturday April 12, 2025, from 12:00-1:00 PM
• Tuesday April 15, 2025, from 12:00-1:00 AM, 2:00-3:00 PM, and 7:00-8:00 PM
• Thursday April 17, 2025, from 12:00-1:00 AM, 2:00-3:00 PM, and 7:00-8:00 PM
The peak parking demand was found to be 24 spaces on the west side of Mary Avenue and six
spaces on the east side of Mary Avenue between 2:00-3:00 PM on Thursday April 17, for a total of
30 occupied spaces.
Additional Parking Counts
The first set of parking counts did not denote where the cars were parked along the street.
Therefore, additional counts were conducted. Counts were counted along Mary Avenue from Lubec
Street and Stevens Creek Boulevard on Thursday April 24, 2025, from 2:00-3:00 PM which was
determined to be the time most parking spaces were occupied (see Attachment 1). Figure 1 shows
the summary of the additional parking counts.

Mary Avenue Affordable Housing Parking Study and Trip Generation Estimate September 8, 2025
P a g e | 3
The peak parking demand based on the additional count was found to be 26 spaces on the west
side of Mary Avenue and 11 spaces on the east side of Mary Avenue, for a total of 37 spaces
occupied on Mary Avenue between Lubec Street and Stevens Creek Boulevard.
Trip Generation Estimates
Hexagon prepared trip estimates for the proposed project using trip generation rates from the
Institute of Transportation Engineers' (ITE) Trip Generation Manual, 12th Edition, 2025 (see Table
1), Senior Adult Housing - Multifamily (Land Use 252) and Affordable Housing (Land Use 223).
Developmentally disabled housing is not a category in the ITE manual. Senior Housing will perhaps
over-estimate the number of trips, but best represents housing for people that are not going to work
or school on a daily basis. Affordable Housing includes multifamily housing that is rented at below
market rate. Eligibility to live in affordable housing can be a function of limited household income,
resident age, or special needs. These ITE land use categories best represent the units proposed.
The developmentally disabled units would be for residents who are unable to operate vehicles, and
the affordable housing units would be for low-income residents.
Based on the trip generation rates, the project would generate 164 new daily trips, with 12 new trips
(three inbound and nine outbound) during both the AM peak hour and 15 new trips (nine inbound
and six outbound) during the PM peak hour. This small number of trips would not cause any
noticeable change to traffic operations on Mary Avenue or other streets in the area.
Table 1 Trip Generation Estimates
Conclusion
The results of the parking study and trip generation estimates are summarized below.
• On Mary Avenue between Lubec Street and Stevens Creek Boulevard, at most 37 vehicles
were parked which occurred during a weekday from 2:00 -3:00 PM.
• The project would generate 164 new daily trips with 12 new trips during the AM peak hour
and 15 new trips during the PM peak hour. This small number of trips would not cause any
noticeable change to traffic operations on Mary Avenue or other streets in the area.
