In December of 2020, City of Cupertino staff initiated a safety and operational study of the Bollinger Road corridor and is a collaboration between the City of Cupertino and City of San José. The project studies Bollinger Road from De Anza Boulevard to Lawrence Expressway and identifies improvements that will enhance pedestrian, bicycle, motor-vehicle, and transit operations and safety.

The efforts performed for the study are summarized in the attached report: Bollinger Road Corridor Study

Project Outreach

As part of the study, an analysis of existing conditions and a summary of past collisions along the corridor was conducted. This was followed by an online outreach portal that gathered public input on location-specific improvement needs along the corridor. The portal gave the users the ability to provide their input through means of a general survey as well as a “social pinpoint” map where users provided location specific input using an online mapping tool. This outreach portal was distributed by City of Cupertino and City of San Jose staff through each City’s respective social media pages on Facebook, Twitter, Instagram, and Next Door as well as working groups such as Walk Bike Cupertino, Bicycle-Pedestrian Commission, and Safe Routes to School. Users were able to provide their input over a course of three weeks.

Proposed Concept Alternatives

The responses and suggestions provided in the first round of outreach were used to guide

concept development. Based upon results from the existing conditions analysis and the public survey, specific improvements were identified that would address the challenges the corridor presents. Two alternatives were created to reflect different priorities and strategies for improving the corridor:

Alternative A includes a road diet where the road would be reduced to one travel lane in each direction, including the provision of a center two-way left turn lane.
Alternative B maintains the existing lane configuration while providing spot improvements, primarily at intersections.

On May 19, 2021, a virtual neighborhood meeting was held to discuss these improvement concepts. Notifications were sent to residents and those who responded during the first round of outreach. Methods of outreach for this event were similar to those used during the first round of public outreach. The meeting included a presentation introducing the study, explaining the existing conditions, summarizing the first round of outreach, and then explaining both proposed concepts along with their key attributes and differences. The meeting also included an interactive discussion session where attendees were able to provide written or verbal questions.

Next Steps

The improvements proposed in this study are intended to be used as a guide to help identify grant opportunities as well as identify future capital improvement projects. Once funding is identified and capital projects are initiated, further design and analysis work will be required. This includes a topographic and utilities survey of Bollinger Road, preliminary engineering and final design, and traffic analysis. The traffic analysis would determine the potential for the road diet (Alternative A) to increase congestion or divert traffic onto residential streets, and any corresponding mitigation measures to limit that impact. Community outreach efforts should continue in future project phases to ensure community awareness and support of the project.
