Floodplain Maps

The FEMA floodplain maps for New Hampshire communities can be viewed at the following locations.

FEMA Map Service Center

The FEMA Map Service Center (MSC) is the official online public source for flood hazard information produced in support of the NFIP. The MSC web site can be used to find current, historic, preliminary (draft), and pending (future) FEMA Flood Insurance Rate Maps (FIRM) as well as the current Flood Insurance Studies (FIS), which can be viewed, downloaded, or printed. Also available are the FIRM and FIS GIS Databases, Letters of Map Changes, and Non-Regulatory Flood Risk Products.


NH GRANIT at the University of New Hampshire is currently a FEMA Cooperating Technical Partner and the host of the state's geographic information system (GIS) clearinghouse. Floodplain mapping for all NH communities except those in Belknap County can be viewed using the following links. To view Belknap County community floodplain maps, please go to the FEMA Map Service Center.

Current NH Floodplain Mapping Activities

The Current NH Floodplain Mapping Activities web page includes information about FEMA's current floodplain mapping activities in New Hampshire.
