*Environmental Review Begins for Mount Tamalpais Road and Trail Management Plan Update*
Marin Water has begun the environmental review process for the proposed Mount Tamalpais Road and Trail Management Plan (RTMP) Update and is preparing a draft Subsequent Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act (CEQA).
Marin Water is updating its 2005 Road and Trail Management Plan to address evolving public access and restoration needs on the Mt. Tamalpais Watershed. The RTMP Update emphasizes watershed restoration and includes proposed road-to-trail conversions, route decommissioning and restoration, reroutes, and targeted changes to access and use.
Marin Water has released the Notice of Preparation (NOP), initiating a public comment period on the scope of environmental issues to be studied in the EIR. This scoping comment period is open through noon on September 28, 2026. Community members can submit comments during this period to help inform the scope of the EIR. Marin Water will also host a public scoping meeting to provide an overview of the project and the EIR process:
Thursday, September 10, 2026, from 4:00–7:00 PM
Sky Oaks Watershed Headquarters
49 Sky Oaks Road, Fairfax, CA 94930
The meeting will be an open-house format, and attendees may drop in at any time to learn more about the proposed RTMP Update and provide comments on the scope of the EIR.
All comments received during this comment period will be reviewed and considered in determining the scope of the EIR.
