The Town of Weymouth's Zoning Ordinance Article XIIA establishes a local floodplain district which includes all Special Flood Hazard Areas designated by the Department of Homeland Security's Federal Emergency Management Agency (FEMA). These flood hazard areas are identified on the FEMA-approved Flood Insurance Rate Maps (FIRMs) for Norfolk County. In 2012, the Town of Weymouth amended its Zoning Ordinance to adopt the latest FIRMs. Although FEMA later revised these maps, the Town received written notification in January of 2014 that the flood hazard areas of Weymouth did not change.
Viewing Flood Maps
FIRM panels are available for viewing online using FEMA's Map Service Center. Residents can search for a property by street address, and no login information is required. Printed FIRM panels are also available for review at Weymouth Town Hall in the Department of Planning and Community Development (third floor) and the Department of Municipal Licenses and Inspections (first floor).
To help residents better understand FIRMs and also learn about the Commonwealth's permitting process for coastal-area construction, the Massachusetts Office of Coastal Zone Management (CZM) has published the fact sheet StormSmart Coasts: Who to Contact and What to Do Before Building or Rebuilding (2014). Please note that the information provided in this fact sheet is accurate as of the date of publication. For updates, please visit the CZM's website.
Reevaluation of Flood Zones & Letter of Map Revision (LOMR)
In 2014 and 2015, the Town sponsored a reevaluation of the Special Flood Hazard Areas designated by FEMA along portions of the Weymouth Fore River. The Woods Hole Group of East Falmouth completed the analysis using coastal engineering methodologies described in the Atlantic Ocean and Gulf of Mexico Coastal Guidelines Update (FEMA, 2007) and Guidance for Coastal Flooding Analyses and Mapping (FEMA, 2003).
The reevaluation was conducted specifically for the Idlewell Boulevard area and the northern shorelines of the Fore River. These areas are covered by FIRM Panel 2502160227F. Results from the Woods Hole Group analysis indicate that changes to some Special Flood Hazard Areas are warranted. These changes include the following:
- A one foot reduction in the Base Flood Elevation (BFE) for the VE (hazardous wave action) Zone along the northern shoreline areas of the Fore River.
- A two foot reduction in the BFE for the VE Zone along the Idlewell Boulevard area.
- A reduction in the width of the VE Zone along both the Idlewell Boulevard area and northern shoreline areas so the Zone does not extend as far inland.
Based on the Woods Hole Group’s analysis, the Town of Weymouth requested a Letter of Map Revision (LOMR) in 2015 to formally revise the aforementioned Special Flood Hazard Areas. FEMA approved the LOMR on May 18, 2016, resulting in the removal of a number of Weymouth properties from the 100-year floodplain. The revised FIRM took effect September 29, 2016.
