DFIRMs

Effective panels (pdf format) of the countywide DFIRMs are available for:

  • Cheshire County
  • Grafton County
  • Hillsborough County
  • Rockingham County
  • Strafford County
  • Sullivan County

    The GIS data supporting the DFIRMs has been released at no cost via the GRANIT Data Download page (theme keyword = flood).

    Preliminary panels (pdf format) of the countywide DFIRMs are available for Merrimack County. These maps are currently being reviewed by the communities, and cannot be used for official floodplain determination at this time. Communities should continue to use their effective FIRMs until the DFIRMs are officially adopted.
