Flood protection

We prepare for every year as if 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.
