Service Description:

This cached tiled map service, hosted at MassGIS' ArcGIS Online site, represents FEMA National Flood Hazard Layer (NFHL) data currently available for Massachusetts. At scales 1:80,000 and closer, flood zone abbreviation labels appear (from the FLD_ZONE field).

The National Flood Hazard Layer (NFHL) dataset represents the current effective flood risk data for those parts of the country where maps have been modernized by the Federal Emergency Management Agency (FEMA). It is a compilation of effective Flood Insurance Rate Map (FIRM) databases and any Letters of Map Revision (LOMR) that have been issued against those databases since their publication date. The NFHL is updated as new data reaches its designated effective date and becomes valid for regulatory use under the National Flood Insurance Program (NFIP).

See full metadata from MassGIS.

All data included in this layer are considered "final" by FEMA. Any preliminary data that appear on maps displayed at community meetings, etc., are not included here.

This map service includes data published by FEMA as of July 2, 2023.
