Please attend an important Neighborhood Meeting to Learn About “Marin Water Pipeline Proposal”, which will affect San Marin Drive.  Lucy Croy, Water Resource Manager of the Marin Water will present with her team. The meeting is scheduled for 7pm, Thursday, March 12th at All Saints Church, 2 San Marin Drive, Novato   

Marin Water is beginning environmental review for a proposed water supply resiliency project that would involve constructing new pipeline and pump station infrastructure in Novato, including along San Marin Drive to connect existing facilities already located in the area.

Called the Atmospheric River Capture (ARC) Project, the proposal would allow Marin Water to store excess winter water captured during key storm events from the Russian River for later use in dry years. To do this, the Marin Water would construct a new 13.2-mile pipeline and supporting facilities that link existing infrastructure in Novato near Hwy 101 with Nicasio Reservoir.

Because portions of the proposed pipeline route would pass through the San Marin neighborhood, Marin Water is holding a special community meeting for members of the San Marin Improvement Association to provide early information on the project. The meeting will introduce the project, share maps of the proposed construction areas, and provide opportunities to answer community questions.

We look forward to seeing you at our neighborhood meeting Thursday, March 12th at 7pm.
