The San Anselmo Flood Risk Reduction Project will reduce the risk of flooding in Ross Valley with the improved former Nursery site providing much-needed, temporary water storage during infrequent, but severe, flood events such as the ones experienced in 1982 and 2005 that caused tens of millions of dollars of damage to private and public property in Fairfax and the lower Ross Valley. The limited in-channel capacity of Sleepy Hollow and San Anselmo Creeks causes flooding in San Anselmo during flood events, and the improved former Nursery would provide temporary water storage, thereby reducing creek overflow and downstream flooding. The Project Environmental Impact Report will analyze flood diversion and temporary storage basin at the former Nursery site, coupled with removal or modification of a commercial building over San Anselmo Creek and creek improvements along Creek Park and downstream, along with three other alternatives and the “no project” alternative. This Project replaces the former Memorial Park Detention Basin project and retains the grant funding authorized for Memorial Park to fund similar flood protection projects within the Ross Valley.
