Town planning staff told the selectmen that FEMA has completed an updated Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) that updates flood hazard areas in parts of Henniker; the maps become effective Nov. 13, 2026. Staff explained that pursuant to RSA 6:74:57, the governing body must adopt the changes for them to be incorporated into the municipality's floodplain regulations.
"The revised maps update flood hazard information in certain areas of Henniker," the planning representative said, and noted the planning board voted to adopt the floodplain ordinance at its August 12 meeting. Selectmen asked about the likely effect on property owners; staff said changes could add or remove properties from mapped zones and directed property owners with questions to the planning department and FEMA resources. A motion to adopt the FEMA FIRMs and FIS by resolution was made, seconded and approved by the board.
