US 101 North Comprehensive Multimodal Corridor Plan (CMCP)

What is a CMCP?

A Comprehensive Multimodal Corridor Plan (CMCP) is a long-range system plan developed in collaboration with State, regional, and local governments and communities to serve growing transportation system needs along a corridor. A CMCP identifies challenges such as congestion and climate change, while evaluating equitable opportunities for bicycle, pedestrian, transit, freight, and rail improvements to support multimodal accessibility. Transportation projects are documented as short-, medium-, and long-term projects to prioritize funding needs for shovel-ready transportation projects. This informs the decision-making process by recommending projects and strategies that will achieve State and regional goals and objectives. With input from stakeholders and communities, the CMCP is a collaborative plan to provide an overall vision for the future of the corridor.

Why do we need to update the US 101 North CMCP?

The current US 101 North CMCP can be found here. The US 101 North Corridor, traversing through Marin and Sonoma Counties, is a critical north-south transportation route serving the movement of people and goods in a variety of transportation modes. This update will better align with Statewide Plans such as the California Transportation Plan (CTP) 2050, the California Climate Action Plan for Transportation Infrastructure (CAPTI), the District 4 Vulnerability Assessment, and the District 4 Adaptation Report to address communities facing climate change threats and prioritize projects to mitigate said threats. The update will also include goals and strategies for neighborhood enhancement and preserving character. These updates will focus on equity, environmental justice, and enhancing communities along the Corridor.

Solutions for Congested Corridors Program (SCCP)

Projects evaluated in the CMCP are eligible for Senate Bill 1: Solutions for Congested Corridors Program (SCCP), a statewide competitive program that funds projects that make specific performance improvements and are part of a CMCP designed to reduce congestion in a highly travelled corridor to provide more transportation choices for residents, commuters, and visitors while preserving the character of the local community and creating opportunities for neighborhood enhancement projects.

How can you get involved?

Public engagement was conducted from Spring 2022 - Summer 2022 through surveys in English and Spanish, virtual webinars, and an in-person workshop where the public shared their experiences and suggestions for transportation along the US 101 North Corridor. Information gathered from this outreach provided invaluable insight of travel needs along the corridor which will be documented in the CMCP to support future funding opportunities for multimodal transportation projects that meets community needs.
