Flood Control and Water Conservation District

The mission of the Marin County Flood Control and Water Conservation District is to reduce the risk of flooding for the protection of life and property while utilizing sustainable practices. The District aims to meet this mission through effective, transparent, and responsive planning, design, construction, operation, and maintenance of County-owned facilities such as stormwater pump stations, detention basins, bypass drains, creeks, ditches, and levees.

About the District

The District’s geographical boundary is the same as the County’s and, as a whole, it has no source of revenue. Instead, revenue is collected via ad valorem taxes and fees paid by property owners in one of eight zones covering distinct geographical areas within the District. All expenditures by the District require authorization by the Board of Supervisors of the District and the five members of the Marin County Board of Supervisors serve on the District’s board.

What We Do

 The Flood Control District prepares for every year as though it is an “El Niño year.” Although two major flooding years in Marin's history occurred during years with El Niño episodes (1997/98 and 1982/83), it is not unusual to experience major flooding in the absence of El Niño, such as in 2005/06. Flooding can even occur during a drought year such as 2015, when the County suffered some of its worst flooding damage since 2006.
