Community Meeting on Tamalpais Valley Flooding

County’s Watershed Program to conduct April 29 workshop to share plans

San Rafael, CA –Tamalpais Valley residents will get a chance to learn about flood risks and what their options are for reducing risk in the future at an April 29 meeting.

A pedestrian walks on a flooded paved pathway near the bay.The Southern Marin Flood Protection and Watershed Program, a collaboration with the City of Mill Valley and local flood control zone advisory boards, is having a public workshop about the future of flood planning at 7 p.m. April 29 at the Tam Valley Community Center, 203 Marin Ave.

Tam Valley, an unincorporated neighborhood between Sausalito and Mill Valley, experiences chronic flooding on sunny days during astronomical high tides and runoff from heavy rain exacerbates the problem. The area is vulnerable to flooding both from high tides and Coyote Creek. In fact, much of the community’s low-lying area was developed by placing earthen fill over former marshlands. Much of the infrastructure, constructed in the 1960s and ‘70s, will need to be evaluated to have the system keep up with anticipated rises in sea level.

Staff from the Marin County Department of Public Works will be on hand to introduce the program, outline the flooding issues and listen to feedback from residents. Program staff is developing a new online watershed guide that explains why and how it floods in that area and potential options for reducing risks.

A meeting flier and program information are available at A second meeting on Coyote Creek flood prevention efforts is planned this summer.
