FEMA Flood Insurance Rate Maps (FIRMs)
Cape Cod Watershed FIRMs Finalized
As of January 22, 2020, FEMA has finalized the Hingham FIRMs within the Cape Cod Watershed based on new hydrologic and hydraulic analyses, or more precise topographic data. In areas where this information was not available, the current floodplain data was incorporated into the finalized FIRMs.
An image of the study area and one of the six preliminary, revised FIRMs is available below. This is the only revised FIRM that reflects changes to the floodplain data outside of Wompatuck State Park. FEMA is conducting a final administrative review of the finalized FIRMs, which may include minor adjustments to the labeling, tables of contents, etc. There will be no changes to any flood zones, base flood elevations, or other technical data as part of this final administrative review.
All of the FIRMs can be downloaded from FEMA’s Flood Map Service Center, currently under “Preliminary Products.” A hard copy of the preliminary, revised FIRMs are also available for review in the Conservation Office. The finalized FIRMs are expected to be available on the same website, under "Effective Products," and in hard copy form by the end of February, 2020. The finalized FIRMs will have an effective date of July 22, 2020.

LOMR, Effective September 8, 2017
On September 8, 2017, FEMA issued a second LOMR to update the Limit of Moderate Wave Action (LiMWA) for Massachusetts. Several Hingham FIRMs were updated with this information (see below). No new coastal analysis was conducted; only the LiMWA was revised. Other effective flood hazard information, including flood zones, flood elevations, and floodway delineations were not revised. The updated LiMWA information is available via FEMA's Flood Map Service Center and the Town's GIS Map.

LOMR, Effective August 14, 2015
The Federal Emergency Management Agency (FEMA) issued a Letter of Map Revision (LOMR) for certain coastal areas in Hingham. This LOMR is based on a Town-sponsored analysis, performed by GZA GeoEnvironmental, Inc., that resulted in changes to the 2012 FEMA Flood Insurance Rate Maps (FIRMs).
These changes went into effect with FEMA on August 14, 2015. The changes were also adopted as part of a Zoning By-Law amendment at the 2016 Annual Town Meeting. The revised By-Law includes an updated Zoning Part B map, which depicts the updated flood zones and replaces the previous version of the map, and new language explaining the purpose of the “Floodplain Protection Overlay District.”
