Floodplain Management Program

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

The Office of Planning and Development (OPD) administers the National Flood Insurance Program (NFIP) in New Hampshire. The NFIP is a partnership between a community and the federal government. Communities participate by agreeing to adopt and enforce a floodplain management ordinance designed to reduce future flood risks and in return all residents in those participating communities (whether in floodplain or not) can purchase flood insurance.

OPD 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. Currently, there are 220 communities (94 percent) in New Hampshire that participate in the NFIP. To learn the status of each New Hampshire community, you can view a map or view the FEMA Community Status Book. For more information on how a community can join the NFIP, please go to the Joining the NFIP page.

Learn more about the NH Floodplain Management Program and how the NFIP is administered in the state by viewing OPD's Introductory Video and OPD’s interactive story map.
