On July 29, 2020, FEMA issued the Letter of Final Determination (LFD) for the Rockingham County portion of the Piscataqua Salmon Falls Watershed – Coastal Project. The LFD establishes the effective date of the new Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) and provides communities six months to adopt the new FIRMs and FIS prior to the effective date. The FIRM effective date is January 29, 2021.
