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
anticipate having all New Hampshire countywide FIS and DFIRMs
(preliminary and/or effective) available for viewing and
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.
