SR 37 Flood Reduction Project – Second Scoping Meeting
December 14, 2022

Caltrans hosted a second virtual public scoping meeting on December 14, 2022 for the proposed SR37 Flood Reduction Project. The purpose of the proposed Project is to address reoccurring flooding issues in low lying areas on SR 37 and accommodate projected 2130 sea level rise. During the first public scoping meeting held on November 17, 2021, Caltrans presented one build alternative that proposed raising the highway on an embankment and modifying four structures and the no-build alternative.

In response to public comments received during the public scoping period, Caltrans reduced the proposed project limits to now extend from U.S. 101 to the Atherton Avenue Undercrossing in Marin County. There are now two build alternatives, which both propose a causeway instead of the originally proposed embankment.

Planning and Environmental Linkages (PEL) Study
September 14, 2022

The goal of the PEL Study is to collaboratively develop planning alternatives that address corridor-wide transportation needs while considering the concerns of communities, agencies, stakeholders, and the public. The PEL Study will lay out a vision for the SR 37 corridor by including different needs, activities, projects, and next steps in one umbrella document, and will help Caltrans understand the sequencing for short-term and longer-term solutions for sea level rise and extreme weather events.
