Downtown Congestion Reduction Plan

In 2015, Lafayette received a planning grant from the Contra Costa Transportation Authority (CCTA) to conduct a comprehensive study of congestion in and around its downtown. ARUP leads a team of consultants are taking a fresh look at a decades-old problem that, to date, has had no easy solution. The team aims to break new ground with a broad range of multi-modal traffic improvement options, applying new technology and techniques. Lafayette will undertake a robust public engagement process to solicit participation from all stakeholders within the community. The City Council has a formed a Steering Committee to guide the consultant team’s effort throughout this study. The intended outcome of this study is a Downtown Congestion Reduction Plan aimed at reducing future traffic growth in and around Downtown Lafayette.

As part of the first phase of the study, the project consultants collected data and assessed existing traffic conditions as well as historical trends in the downtown area. ARUP then presented a briefing to a joint session of the City Council and Circulation Commission in November 2015 at the Community Hall at the Lafayette Library and Learning Center. Following this meeting, Lafayette launched a web-based survey to gather public opinions about traffic concerns and priorities to inform the consultants’ next step: developing a range of solutions for further public discourse. The survey ran from mid-November through December 2015. The results of that survey can be viewed here. After that survey, during winter/spring 2016, the Steering Committee reviewed the universe of potential solutions suggested in past transportation studies, Circulation Commission and Council study sessions, as well as the aforementioned public survey. ARUP applied high-level quantitative and qualitative analysis to potential solution ideas, which the Steering Committee subsequently evaluated. The first study phase completed when the Plan Steering Committee distilled that universe of all of the potential solutions into a “Short List” of the most promising traffic congestion reduction strategies.

The second study phase commenced in summer 2016. During this phase, the Steering Committee holistically evaluated the Short List of ideas using rigorous traffic models and a multi-criteria assessment method developed by ARUP. Based on this evaluation, the Steering Committee formed a preliminary recommendation of 15 congestion reduction strategies, to be vetted by the City Council, Circulation Commission, and the general public.  In late April 2017, ARUP returned to a joint session of the City Council and Circulation Commission, and presented the Steering Committee’s 15 recommended congestion reduction strategies and to introduce a second round of public outreach.

Since that presentation, the City has launched a new round of public outreach to gather community opinions on the 15 congestion reduction strategies proposed by the Steering Committee. This round of outreach consists of a web-based survey and a public workshop. The survey is now open and will continue through May 31, 2017. Members of the public interested in submitting their opinions on the 15 recommended strategies may access the survey here. There are just two questions in the survey, supplemented by strategy descriptions and links to background technical reports. During the month-long survey period, the City will also host a public workshop, to gather feedback in person. This workshop is scheduled for Tuesday, May 23, 2017, from 7 – 9pm, at the Lafayette Veterans’ Memorial Center (3780 Mt. Diablo Blvd., Lafayette, CA 94549).

Once armed with additional public feedback, Lafayette hopes to develop a preferred plan that will serve as a long-term blueprint for future transportation projects and programs that will sustain a vibrant and viable Downtown Lafayette for many years to come.
