Resilient 37

Planning a More Resilient

Highway 37 for All

Think about Highway 37 as more than just a commute! The future of this corridor demands finding solutions to chronic traffic congestion and periodic flooding. But it will also require balancing transportation needs with protecting and enhancing sensitive marshland habitats. Planning a long-term solution presents an opportunity to provide bicycle, pedestrian, transit, and carpool options for all travelers.

Help Plan for the Future of State Route 37: Ultimate Solution for US 101 to I-80 Corridor – January 25, 2022

The State Route 37 (SR 37) Planning and Environmental Linkages (PEL) Study team invites you to a virtual public meeting on January 25, 2022. At the meeting, staff will update stakeholders and the public on the PEL Study, the Purpose and Need statement, and gather input on the evaluation criteria and preliminary alternatives.

It is critical that community members who rely on SR 37 have opportunities to provide input on the planning process. Mark your calendar for January 25 and join the meeting to share your ideas for the future of the SR 37 Corridor. Details will be posted on the project website.

State Route 37 Sears Point to Mare Island Improvement Project – Wednesday, February 2, 2022 5:30 pm to 7:00 pm

The California Department of Transportation (Caltrans) has initiated a public review period and is conducting a virtual public meeting on the Draft Environmental Impact Report (EIR)/Environmental Assessment (EA) for the proposed State Route [SR] 37 Sears Point to Mare Island Improvement Project in Sonoma, Napa, and Solano counties.

Caltrans — in cooperation with the Metropolitan Transportation Commission and the North Bay partner agencies of Sonoma County Transportation Authority, Solano Transportation Authority, and Napa Valley Transportation Authority — is proposing traffic operational improvements to SR 37 in Sonoma, Napa, and Solano Counties between Sears Point (Son-37-Post Miles 2.9/6.2) and Mare Island (Sol-37-Post Miles 0.0/R7.4) to provide congestion relief, reduce peak travel times, and increase vehicle occupancy.

Draft EIR/EA:
Caltrans has prepared a Draft Environmental Impact Report/ Environmental Assessment (EIR/EA) for the proposed project. It is available online at Caltrans District 4 Environmental Documents webpage.

Virtual Public Meeting:
The virtual public meeting will include a presentation providing an overview of the project and the environmental process, followed by a question and answer session where attendees can submit questions via online chat. However all formal comments on the EIR/EA must be submitted in writing.

One Corridor, One Team, Many Solutions

While Caltrans, the Metropolitan Transportation Commission, and transportation authorities for Marin, Napa, Solano, and Sonoma counties are already implementing short-term improvements, other challenges require a suite of longer-term solutions:

Three coordinated efforts are underway to formulate these solutions:

- - - 1.) An Ultimate Resilient Design Alternatives Assessment focused on Highway 37 within Marin and Sonoma counties between U.S. 101 and Highway 121.
    - Please click here to view the recent update on the DAA provided to the State Route Policy Committee on January 6, 2022.
- 2.) A Comprehensive Multimodal Corridor Plan collaboratively identifies goals, corridor needs and challenges, and project priorities for various modes of travel to inform decision-making and future funding.
- Click Here to view the Comprehensive Multimodal Corridor Plan
- 3.) A corridor-wide effort known as the Planning and Environmental Linkage study will identify and narrow the range of alternatives to be advanced for environmental review and construction.
Each of these efforts need your input! Take this Survey to provide us with your input! These studies are integrated to deliver a roadway that will serve both long-term transportation needs and the environment

How High Should the Future Highway 37 Be?

The level of the San Francisco Bay could rise five to seven feet by 2100 under high greenhouse gas emission scenarios, according to 2018 projections by the California Ocean Protection Council. With high tides during a large storm, this translates into the need to raise Highway 37 by at least 20 feet.

What is the Vision for Highway 37?

A long-term plan should last a generation or more. We need to anticipate changes in the landscape and the transportation needs of the region. Think of the people and the areas that Highway 37 serves, how the highway interacts with the built environment and wildlife, and how future residents will be using this area. That is where a vision starts.

How Will My Input Be Used?

The Highway 37 Team is seeking input from engaged stakeholders and members of the public to inform solutions and strategies. Your recommendations will be summarized and forwarded to transportation planners and highway designers.

A highway has many elements—alignment route, travel lanes, connection points, bridges, and waterway passages—with options for bicyclists, pedestrians, and transit. Highway 37 is affected by the surrounding landscape, including agricultural lands, natural habitat, and the built environment. What elements do you see as part of the solution and what considerations should be evaluated or protected? It’s One Corridor – many solutions! Your ideas will help shape these potential solutions, the evaluation, and the final project.

When Can We Expect These Improvements?

Our team is taking a phased approach; addressing the most immediate challenges now, while we seek your input on longer-term solutions. Work has already begun on some of the shorter-term solutions, including raising the roadway and installing floodwalls in areas most vulnerable to flooding. Another short-term project is reducing congestion through the addition of a high occupancy vehicle (HOV) lane between Highway 121 and Mare Island.

Medium- and long-term solutions will require more study and evaluation by engineers, regulators, and the public. The roadmap below outlines the primary planning phases and key milestones all the way through construction. As you can see, there will be lots of opportunities for public input throughout the process.
