FEMA Information


FEMA publishes the official flood maps of San Anselmo, which delineate the spatial and vertical extent of the Base Flood, or 100-year flood.

FEMA also administers the National Flood Insurance Program. The following links have more information about the NFIP:
The following links provide ways of viewing the most current flood maps and determining if your building is subject to the special requirements of the flood zone:

Flood insurance rates are adjusted based upon a building's elevation above the Base Flood, therefore elevation certificates are important as a means of collecting and certifying this information. San Anselmo collects elevation certificates through permitting and makes them available to the public.
