Subject: Local Transportation Analysis for the Proposed Residential Development at 1655 S.
De Anza Boulevard in Cupertino, California.
Hexagon Transportation Consultants, Inc. has completed a Local Transportation Analysis for the proposed residential development at 1655 S. De Anza Boulevard in Cupertino, California. The project site is located on the northwest corner of the intersection of S. De Anza Boulevard and Prospect Road (see Figure 1). The project site currently is occupied by several commercial uses.
The proposed project would demolish the existing commercial buildings on site and construct 35 townhome units (see Figure 2). Access to the townhomes would be provided via two driveways, with one driveway on De Anza Boulevard and one driveway on Prospect Road.
Transportation Analysis Scope
This study was conducted for the purpose of identifying 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 Analysis Guidelines (January 2025).
Based on the City’s TA Guidelines, traffic studies are separated into 3 tiers:
• Tier 1: Less than 110 daily trips
• Tier 2: Between 110 and 1,000 daily trips and less than 100 peak hour trips • Tier 3: Greater than 1,000 daily trips or greater than 100 peak hour trips The proposed project would generate five net new trips during the AM peak hour and no net new daily trips or net new trips during the PM peak hour.
(see Table 1 below). Based on the City’s TA Guidelines, a Tier 1 transportation study is required for this project.
This project is being processed under an AB 130 exemption. Therefore, a study of potential impacts under the California Environmental Quality Act (CEQA) is not required. Accordingly, a VMT analysis was not conducted for this project.
Per the TA guidelines, a local transportation analysis consisting of a review of site access and circulation for all modes of travel was completed for this project.

Non-CEQA Analysis
Trip Generation
Through empirical research, data has been collected that shows the 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 (2025). The magnitude of traffic added to the roadway system by the development is estimated by multiplying the applicable trip generation rate by the size of the development. The rates published for “Single Family Attached Housing” (Land Use Code 215) were used for the dwelling units (see Table 1).
The existing site is developed with approximately 11,650 square feet of retail buildings. The proposed project would demolish the existing buildings on site. Trips generated by the existing development were counted on April 23, 2026, at the driveways on De Anza Boulevard and Prospect Road (see Appendix A). Existing daily trips were estimated by applying the ratio of daily trips to total peak hour trips based on the ITE trip rates for the land use “Strip Retail Plaza <40K” (Land Use Code 822) to the existing peak hour total trips. After taking credit for existing uses on the project site, the proposed residential development five net new trips during the AM peak hour and no net new daily trips or net new trips during the PM peak hour.

Site Access and Circulation Plan Review Checklist
The City’s Transportation Analysis Guidelines require all studies to review various elements as outlined in the Site Access and Circulation Plan Review Checklist (Table A-7 in the Guidelines).
General Plan Consistency
As stated in the Guidelines’ checklist, the project needs to be evaluated against goals, policies, and actions set forth in the following documents, as they relate to transportation topics:
• Plan Bay Area 2050
• Santa Clara Valley Transportation Authority VTP 2050
• Santa Clara County Active Transportation Plan
• Congestion Management Program Monitoring and Comformance Report • Cupertino General Plan
• City of Cupertino Climate Action Plan
• City of Cupertino Bicycle Transportation Plan
• City of Cupertino Pedestrian Transportation Plan
• City of Cupertino Transportation Impact Fee Nexus Study • Cupertino Municipal Code
• City of Cupertino Local Roadway Safety Plan
• Cupertino Vision Zero Action Plan
• City of Cupertino Active Transportation Plan
Plan Bay Area 2050
The project is consistent with the Plan Bay Area 2050’s following Transportation Strategies:
• T8 Build a Complete Street Network: The project proposes a pedestrian-friendly design featuring internal walkways and maintained sidewalks along its frontages on S. De Anza Boulevard and Prospect Road. It would not interfere with any existing bicycle, pedestrian, or transit facilities.
Other strategies as outlined in the Plan Bay Area 2050 are municipal or regional efforts and are not applicable to the proposed project.
Santa Clara Valley Transportation Authority VTP 2050
VTP 2050 is Santa Clara County’s county-level plan and includes a list of planned infrastructure projects. The project would not affect any of the listed projects.
Santa Clara County Active Transportation Plan
The Santa Clara County Active Transportation Plan outlines a set of goals and priority projects for county-maintained roads. Within the immediate vicinity of the project site, there are no countymaintained roads. Therefore, this plan is not applicable to the proposed project.
VTA Congestion Management Program Monitoring and Comformance Report VTA’s Congestion Management Program (CMP) seeks to reduce congestion at a regional scale through a multimodal approach. The CMP evaluates transportation infrastructure congestion for a list of roadways and intersections. For development projects that generate 100 or more net new peak hour trips, an evaluation following the CMP guidelines and of the CMP transportation facilities 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 6
is required. The intersection of De Anza Boulevard and Prospect Road is a CMP intersection. The project would add five net new trips during the AM peak hour and no new trips during the PM peak hour. Since the number of project added trips are less than 100 during either peak hour, a CMP evaluation is not needed.
Cupertino General Plan
The project is consistent with the Cupertino General Plan’s Mobility Element. See a detailed discussion below.
Policy M-1.2 Evaluate new development and
redevelopment projects pursuant to
the City’s adopted Transportation
Study Guidelines evaluation criteria.

redevelopment to provide inter-block
connectivity to allow improved
access to all sites on the block from
secondary streets, access to the
street network via controlled
intersections, minimize conflicts with
pedestrian and bicycle traffic on
primary streets, and convenient
access for service vehicles.
Consistent. The project would consolidate
existing driveways along its frontages to
provide one driveway per frontage on S. De
Anza Boulevard and Prospect Road. This
would minimize conflicts with pedestrian and
bicycle traffic on these streets.
The internal drive aisle is also designed to
provide connectivity through the site, allowing
for efficient circulation of service and
emergency vehicles.
Policy M-2.5 Ensure all new public and private
streets are publicly accessible to

plan does not show gates or other physical
restrictions that would impede public
pedestrian access through the site.
Policy M-3.2 Require new development and
redevelopment to increase
connectivity through direct and safe
pedestrian connection to public
amenities, neighborhoods, shopping,
and employment destinations
throughout the city.
Consistent. The project would upgrade the
existing sidewalk along the S. De Anza
Boulevard and Prospect Road frontages to
provide a landscaped buffered sidewalk.
Internal pathways would connect the
proposed townhomes to the public pedestrian
network.
Policy M-3.5 Minimize the number and the width
of driveway openings.
Consistent. The project proposes to eliminate
one driveway on each street frontage.
Currently, the site is served by two driveways

not proposed for this residential townhome
development as residents have private
garages for maintenance.
Cupertino Climate Action Plan
The City of Cupertino’s Climate Action Plan 2.0 documents the City’s efforts in reducing greenhouse gas (GHG) emissions and mitigating climate change impacts. The plan outlines a list of GHG emissions reduction measures. The project supports these goals by providing higher-density housing near a transit-served corridor, though specific municipal measures are not directly applicable to the project’s transportation scope.
City of Cupertino Local Roadway Safety Plan, Vision Zero Action Plan The project site is not located in the vicinity of the City’s high injury network. It would not affect any proposed improvements in the City’s Local Roadway Safety Plan or Vision Zero Action Plan.
City of Cupertino Bicycle Transportation Plan, Pedestrian Transportation Plan The project is located at the intersection of S. De Anza Boulevard and Prospect Road. In the vicinity of the project site, S. De Anza Boulevard has Class II bike lanes and Prospect Road has Class II buffered bike lanes. The project would not conflict with these existing facilities. The City’s Bicycle 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 8
Transportation Plan and Pedestrian Transportation Plan do not propose improvements in the vicinity of the project site or along its frontage.
City of Cupertino Transportation Impact Fee Nexus Study The Transportation Impact Fee Nexus Study (Nexus Study) provides the City of Cupertino with the necessary technical documentation to support the adoption of Citywide Transportation Impact Fee Program (TIF Program). There are no proposed TIF improvements in the vicinity of the project site. The project will be required to pay its TIF fee. Therefore, the project is consistent with the TIF Nexus Study.
Cupertino Municipal Code
The Cupertino Municipal Code outlines various provisions related to transportation. The project is consistent with the Cupertino Municipal Code. Code sections relating to transportation that are applicable to the proposed project are discussed below:
• Chapter 14.04 Street Improvements. This chapter requires developments to construct or fund the street, sidewalk and utility improvements necessary to support safe and adequate public infrastructure around their project. The project is consistent. The project will provide a landscaped buffered sidewalk along the S. De Anza Boulevard and Prospect Road frontages.
• Section 17.04.040 (C) Vehicle Miles Traveled Technical Report Requirements. Project applicants shall prepare a vehicle miles traveled (VMT) analysis, which shall include a comparison of existing VMT and project-generated VMT, for review and approval prior to project approval, indicating that the project meets the standards in Section
17.08.040 (Vehicle Miles Traveled (VMT) Standards). Not Applicable. The project is being processed via AB 130 and a VMT analysis is not required. • Chapter 17.08 Evaluation of Transportation Impacts Under the California Environmental Quality Act. Not Applicable. The project is being processed via AB 130 and a VMT analysis is not required.
• Section 19.46.070(F) Vehicular parking shall not be located along primary frontage.
The project is consistent. Vehicular parking would be located in private garages or internal guest stalls, and no vehicular parking would be located along the primary street frontages of S. De Anza Boulevard or Prospect Road.
• Section 19.46.070(G) Corner Triangle and Sidewalk Site Triangle shall remain free and clear of all buildings or portions thereof. Not Applicable. Since the intersection of De Anza Boulevard and Prospect Road is a signalized intersection, this section does not apply to the project.
• Section 19.46.070 (J) No more than two vehicular entries/exits per street frontage between the residential development and the public right-of-way. The project is consistent. One vehicular entry/exit is proposed on S. De Anza Boulevard and one vehicular entry/exit is proposed on Prospect Road.
• Section 19.124.030 (A)(2) Vehicles may be placed, kept or parked in the front yard, Street side setback area or within 12 feet of a public right-of-way in a rear yard area, provided a minimum clearance of three feet is maintained from any structure. The 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 9
project is consistent. No parking within setbacks or within 12 feet of the public right-of-way is proposed. All resident parking would be contained within garages.
Parking
The proposed project site is located within a Commercial/Office/Residential (CG, Res 5-15)) district.
The City of Cupertino minimum parking requirement for townhomes in this district per the City’s Zoning Code is one parking space per dwelling unit. Based on the parking code, this would equate to 35 required parking spaces for the 35 units. According to the site plan, the project is proposing to provide a total of 77 vehicle spaces, including 70 resident spaces (provided via private two-car garages for all units) and 7 guest parking spaces. This is higher than the City’s minimum parking requirement.
City Municipal Code 19.124.040(A) does not have bicycle parking standards for Townhome developments. The project would provide 35 long-term bicycle spaces (one per unit) located within the private garages and 4 short-term bicycle spaces for visitors located near the building entrances.
On-Site Circulation
The site access and on-site circulation evaluation is based on the project’s site plan (see Figure 2).
Site access was evaluated to determine the adequacy of the site plan with regard to geometric design, sight distance, and general operations. On-site vehicular circulation and parking layout were reviewed in accordance with generally accepted traffic engineering standards and transportation planning principles. Truck access and on-site circulation were also evaluated.
Driveway Design and Operations
The City’s Transportation Analysis Guidelines (Table A-7) state the following regarding driveway placements:
Indicate whether driveways are proposed on the following facilities:
• High-injury networks (refer to the Local Roadway Safety Plan and the Vision Zero Action Plan)
• High-pedestrian activity zones
• Existing or planned Class IV cycle tracks
• Frequent transit networks or major transit stops
Driveways are not prohibited on these streets; however, they should be avoided when possible and prioritize safety and movement of people walking, bicycling, and riding transit when avoidance is infeasible. Driveways should be located on minor streets and alleyways when possible.
The site currently has two driveways on each frontage; the project would consolidate access to one driveway per frontage to reduce vehicle–pedestrian–bicycle conflict points. Both driveways would meet the 20-foot minimum width requirement for emergency vehicle access, with widths varying from 20 to 26 feet.
S. De Anza Boulevard is classified as an arterial roadway, and Prospect Road is classified as a minor collector roadway. S. De Anza Boulevard has existing transit service and both streets have existing bicycle facilities. The project frontage along S. De Anza Boulevard does not have a bus stop. Class IV cycle tracks are not planned on either roadway along the site frontages. Furthermore, the project is not located along a high-injury network. 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 10
During the AM peak hour, the project is estimated to generate 4 inbound trip and 12 outbound trips and during the PM peak hour, the project is estimated to generate 11 inbound trips and 7 outbound trips. Given the minor number of vehicles using the driveways at any one time, the driveways are expected to operate well.
Sight Distance
The project driveways should be free and clear of any obstructions to provide adequate sight distance ensuring that exiting vehicles can see pedestrians on the sidewalk and vehicles and bicycles traveling on De Anza Boulevard and Prospect Road. 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 and exit a driveway.
Any landscaping and signage should be located in such a way to ensure an unobstructed view for drivers exiting the site. Trees near the driveways should have high canopies so as to not obstruct the view of drivers.
The minimum acceptable sight distance is the Caltrans stopping sight distance. The design speed on S. De Anza Boulevard is 45 miles per hour. According to Caltrans sight distance standards, the stopping sight distance for De Anza Boulevard is 360 feet. The site plan ensures that the corner sight triangles and sidewalk sight triangles remain free and clear of buildings or tall obstructions to maintain this required line of sight. The design speed on Prospect Road is 35 miles per hour.
According to Caltrans sight distance standards, the stopping sight distance for Prospect Road is 250 feet. No obstructions are present on the site plan that would limit available driveway sight distance along Prospect Road. On-street parking is prohibited along the project frontages on Prospect Road and De Anza Boulevard in the vicinity of the site, ensuring that parked vehicles do not interfere with the sight lines of drivers exiting the driveways.
Recommendation: Per City’s Standard Detail, trees’ lower branches shall be trimmed up to 8 feet 6 inches from the street grade along the project frontages. As part of ongoing maintenance, it is recommended that the tree branches be maintained as such.
On-Site Vehicular Circulation and Parking Layout
Within the site, resident vehicle parking for each unit would be provided in attached two-car garages accessed through the internal 20 to 26-foot-wide drive aisles (see Figure 2). Visitor or other shortterm vehicle parking would be provided in seven surface parking spaces located in the center of the project site.
The parking for the project is designed to meet the City of Cupertino’s standard requirements. The private garages would provide tandem spaces at 10' x 20' and standard side-by-side garages at 20' x 20’. All proposed parking spaces would meet or exceed the City’s standard dimension requirement of 8.5 feet wide and 18 feet deep. Within the site, the internal drive aisles are configured to allow for two-way traffic and provide sufficient backing space for all garages. 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 11
Emergency Vehicle Access
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 includes a continuous internal roadway that connects the S. De Anza Boulevard driveway to the Prospect Road driveway. This "flow-through" design allows emergency vehicles to travel through the entire site without the need to turn around. Both project driveway widths vary between 20 to 26 feet along their length, and there would be no vertical limitations or dead-end spurs exceeding 150 feet. Therefore, the project would meet the City’s fire access requirements.
Garbage Collection
The site includes an internal roadway system that allows for service vehicle circulation. As shown on Figure 3, garbage trucks would enter from one street and exit via the other.
Pedestrian Facilities
Pedestrian facilities in the project area consist of sidewalks along the streets, marked crosswalks with curb ramps at intersections, and pedestrian signals and push buttons. The intersection of S. De Anza Boulevard and Prospect Road has crosswalks, pedestrian push buttons, and curb ramps on all four legs. The curb ramp at the southwest corner of the intersection is not ADA compliant.
The project would provide a landscaped buffered sidewalk along the S. De Anza Boulevard and Prospect Road frontages. As described in the previous section, the consolidated driveways along S.
De Anza Boulevard and Prospect Road frontages would reduce conflict points with vehicles and improve pedestrian walkability.
Within the site, a network of 4 to 5 feet wide pedestrian walkways connecting all the townhomes and the visitor parking would be provided. These walkways include a sidewalk along the internal street as well as walkways on the north side, south side, and east side of the proposed buildings.
The north and south side walkways would provide direct access to the S. De Anza Boulevard sidewalk. The east side walkway would end at the southmost townhome and would not connect directly to Prospect Road. It is recommended that this walkway be extended to connect directly to Prospect Road.
The internal street would have stamped asphalt crosswalks at several locations to indicate pedestrian crossing locations and also provide potential traffic calming benefits. Stamped asphalt would also be provided at the internal intersection. It is recommended that ADA accessible curb ramps be provided at the internal intersection.
Recommendation: The internal pedestrian walkway on the east side of the proposed buildings should be extended to connect directly to Prospect Boulevard.
Recommendation: ADA accessible curb ramps should be provided at the internal intersection.

Bicycle Facilities
Existing on-street bicycle facilities along the project frontage include Class II bike lanes along S. De Anza Boulevard with a buffered bike lane on the east side north of Prospect Road, and Class II buffered bike lanes along Prospect Road west of Galway Drive as shown on Figure 1. These bike lanes provide access to parks and commercial uses along S. De Anza Boulevard and Prospect Road as well as De Anza College. The project would not have any impact on existing bicycle facilities.
Transit Services
Existing transit service in the vicinity of the project site is provided by VTA. The project site is served by VTA local route 51 as shown on Figure 1. This route provides service between Moffett Field/Ames Research Center and West Valley College, with a stop located directly across from the proposed project and approximately 1,000 feet north of the project on De Anza Boulevard. It operates with approximately 30-minute headways generally between 6:00 AM and 8:00 PM on weekdays.
According to the U.S. Census, transit trips comprise approximately two percent of the total commute mode share in the City of Cupertino. For the proposed project, assuming two percent of total commute trips would be transit trips, there would be approximately one transit trip in both peak hours. This volume of transit trips generated by the project would not exceed the carrying capacity of the existing transit service to the site.
Per VTA TIA Technical Guidelines, a project would create an impact on transit if: (1) it would cause a permanent or temporary reduction of transit availability or interference with existing transit users (relocation/closure of a transit stop or vacation of a roadway utilized by transit) or (2) it would result in significant delays in transit service. The project, by itself, would not preclude, modify, or otherwise affect existing or proposed transit projects or policies identified by the VTA. The project is not expected to increase delays in transit service. Consequently, the project would not result in any significant impacts to transit service.
Safety Assessment
The project would generate mostly passenger vehicles, and the surrounding roadway system is designed to accommodate these vehicles. Per discussion above regarding the site plan review, the project would not worsen existing geometric hazards or create new geometric hazards. 1655 S. De Anza Boulevard Residential Development Transportation Analysis July 21, 2026 P a g e | 14
Conclusions
The results of the transportation analysis for the 1655 S. De Anza Boulevard project are summarized below.
• The proposed project would generate five net new trips during the AM peak hour and no net new daily trips or net new trips during the PM peak hour. Per the City of Cupertino’s Transportation Study Guidelines, the project meets the City’s trip generation definition for a Tier 1 transportation study.
