San Anselmo Flood Risk Reduction Project

Description

The Marin County Flood Control and Water Conservation District has been working since 2016 on the San Anselmo Flood Risk Reduction Project (SAFRR), which is a significant and complex effort to protect lives and property by decreasing flood risk during severe storms. 

SAFRR has three major elements: the flow diversion and storage (FDS) basin, near Fairfax, where Sunnyside Nursery used to be located (constructed in 2022); the removal of buildings (completed in 2020); the Building Bridge 2 (BB2) structure in downtown San Anselmo, along with creek bank improvements; and flood mitigation of building structures downstream of BB2 that are affected by its removal.
