Additional important information: A portion of Corte Madera lies within a Special Flood Hazard Area (SFHA), more commonly referred to as the "floodplain". This SFHA consists of properties within zones AE and VE as delineated on a Flood Insurance Rate Map (FIRM) prepared by FEMA for our community. The FIRM can be viewed at the Public Works Department office, and assistance can be provided in determining if your property is within the SFHA.
Associated with these zones is a Base Flood Elevation (BFE). This BFE represents the level to which a flood having a 1% chance of being equaled or exceeded in any given year (commonly called the "100-year" flood) will rise. For Corte Madera, the BFE is equal to an elevation of 10 NAVD (North American Datum).
