Flood Control Zone 1 is a subarea of the countywide Flood Control & Water Conservation District. Flood Control Zones were created for specific areas of the county that experience frequent flooding.
Flood Control Zone 1 was created by the Board of Supervisors of the Marin County Flood Control & Water Conservation District to improve flood protection for businesses, government and emergency service facilities, homeowners and residents in the watershed. It was the first flood control zone to be created in Marin County.
Flood Control Zone 1 is made up of all real estate parcels within the Novato Creek watershed.
