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.
News and Updates:
- FEMA is moving forward with updating the National Flood Insurance Program’s (NFIP) risk rating methodology. The new system called Risk Rating 2.0 will make flood insurance rates more equitable and actuarially sound and better reflect a property’s actual risk. Get more details on FEMA’s Risk Rating 2.0 webpage and the New Hampshire State Profile fact sheet which provides projections on how NH policyholders are anticipated to be affected by the changes.
- Updated flood maps for coastal portions of Rockingham County flood maps became effective on January 29, 2021. More information about the new maps is available on the Rockingham County Coastal Project page.
