The Federal Emergency Management Agency (FEMA) has published a revised floodplain map which is effective as of Monday, March 17, 2014. Through its Flood Hazard Mapping Program, FEMA identifies flood hazards, assesses flood risks, and partners with states and communities to provide accurate flood hazard and risk data to guide them to mitigation actions. Flood Hazard Mapping is an important part of the National Flood Insurance Program (NFIP), as it is the basis of the NFIP regulations and flood insurance requirements.
The revised FEMA floodplain map can be found at marinmap.org along with other useful information regarding the NFIP. Note: To find a parcel using the marinmap site, click on the following link Floodplain Map, pull down the menu options under "I want to..." and search by property ID (assessor's parcel number) or by property address. Information can also be found at the FEMA website. Alternatively, the FEMA Floodmap can be viewed in Mill Valley's City Hall at the Planning Counter.
There will be one more round of updates and potential modifications to the revised Floodplain map which will be released later this month. For more information, please see the City's floodplain management page.
