New Hampshire's Statewide GIS Clearinghouse


Welcome to the New Hampshire GRANIT Flood Insurance Study (FIS) and Digital Flood Insurance Rate Maps (DFIRMs) repository. The purpose of this site is to disseminate digital versions (pdfs) of the FEMA (Federal Emergency Management Agency) FIS and DFIRM panels to the public. We anticipate having all New Hampshire countywide FIS and DFIRMs (preliminary and/or effective) available for viewing and downloading.

GRANIT is pleased to announce that the effective FIS and DFIRMs for Carroll, Cheshire, Coos, Grafton, Hillsborough, Merrimack, Rockingham, Strafford, and Sullivan Counties are now available through this website.

Previously, FEMA created paper versions of the Flood Insurance Rate Maps for individual communities. As part of its original Map Modernization program, and more recently its Risk MAP initiative, FEMA and its mapping partners are now creating digital, seamless, countywide products. These improved products incorporate updated base maps, letters of map change (LOMCs), and revised studies (where conducted). In addition, their digital format will allow for more efficient and timely future map updates.

The Flood Insurance Study tab links you to digital versions of countywide Flood Insurance Study documents.

The DFIRMs tab allows you to access the formatted map panels.
