Floodplain Management Program

An overview of New Hampshire's Floodplain Management Program and the information and services it offers

The Office of Strategic Initiatives, (OSI) administers the National Flood Insurance Program (NFIP) in New Hampshire. OSI provides technical assistance and training to communities and the public on floodplain management and helps to promote sound land use planning techniques that will reduce flood losses. Learn more about the NH Floodplain Management Program and how the NFIP is administered in the state by viewing OSI’s interactive story map and the About the Program page.

OSI’s NH Flood Hazards Viewer is an online tool to view current, pending, and preliminary FEMA floodplain mapping for all NH communities (except those in Belknap County, which can be viewed using the FEMA Map Service Center). The Viewer allows a user to view and compare the latest effective and preliminary or pending FEMA flood hazard information along with parcel boundaries and contour data for most areas of the state.

  • The New Hampshire (NH) Department of Environmental Services Coastal Program, in partnership with the Rockingham Planning Commission, Strafford Regional Planning Commission, University of New Hampshire Cooperative Extension, and New Hampshire Sea Grant, is accepting applications for non-financial technical assistance offered through the NH Flood Smart Seacoast Project in order to help NH coastal communities: incorporate best available coastal flood risk science and guidance in decision-making, adopt higher floodplain management standards, and access FEMA Hazard Mitigation Assistance funding. Learn more about the application, eligible communities, and project timeline on the project webpage.
  • FEMA has updated the NFIP’s risk rating methodology through the implementation of a new pricing methodology called Risk Rating 2.0. While Risk Rating 2.0 was introduced to all new policies starting last October, all remaining policies will be subject to the new rating methodology renewing on or after April 1, 2022. Learn more about Risk Rating 2.0 including our outreach toolkit, upcoming trainings, and additional resources.
