Summary

City staff presented the Mount Diablo Corridor multimodal (M3) study concept and a portfolio of projects (BART Town Center bike station, Connecting Lafayette, smart signals, Aqueduct pathway); staff said design funding is secured and some construction funding is programmed for 2029 and asked the commission to nominate a member for a proposed multimodal advisory committee.

The Transportation and Circulation Commission on April 20 reviewed a coordinated portfolio of downtown and corridor projects grouped under a proposed Mount Diablo Corridor multimodal mobility study (M3) and heard that design funding is in hand for several segments while construction funding for parts of the Aqueduct pathway is programmed for 2029.

Why it matters: the M3 study is intended as a 20‑year vision and implementation framework to improve safety, walking and biking access to BART, reduce short auto trips in downtown and align projects for future grant competitiveness under MTC programs.

A city staff presenter summarized projects under construction and in design, including the BART Town Center bike station improvements, a Class I path on School Street (Connecting Lafayette), planned smart‑signal work through CCTA, and the Aqueduct pathway (design funded from Dolores to the BART area). The presenter said the Aqueduct pathway construction is funded in the capital program but that construction funding for a downtown segment is not available until 2029.

Staff also described related planning work: a BART station access and circulation study funded by MTC to support compliance with MTC’s Transit‑Oriented Communities (TOC) policy, a downtown parking management study, and two technical substudies to be incorporated in M3 (a right‑turn‑on‑red evaluation on Mount Diablo Boulevard and a Moraga Road redesign concept ahead of resurfacing).

Commissioners asked for the M3 RFP and scope documents; staff said three proposals were received and that a consultant selection and a study kickoff were expected by early summer 2026. Staff also said it will ask the city council next week to form a multimodal mobility advisory committee and expects to fill commission, council and at‑large seats before the study begins.

Funding discussed included STIP (state) dollars programmed for the Dolores‑to‑BART segment and the possibility of an earmark being pursued by Desaulnier for Brown-to‑Pleasant Hill segments; staff did not provide detailed dollar amounts for each element during the meeting.

The commission had no public comments on the item and moved on to committee updates.
