FEMA Flood Insurance Information

Please be advised that the Federal Emergency Management Agency (FEMA) has issued newly revised Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS), effective March 16th, 2016. The City of Chelsea has, according to a mandate by the National Flood Insurance Program (NFIP), modified the regulations pertaining to flood plains within the City's Zoning Ordinance.

Looking for a flood map? You can access your map via FEMA Flood Map Service Center.

If a property owner thinks their property has been inadvertently mapped in a Special Flood Hazard Area (SFHA), they may submit a request to FEMA for a Letter of Map Change.
