NH Flood Hazards Viewer

The NH Flood Hazards Viewer is a new online map viewer that includes the same effective FEMA flood hazard information that you’ll find on Flood Insurance Rate Maps (FIRMs) and FEMA’s online map viewers. However the NH Flood Hazards Viewer also includes other map layers including:

 Preliminary FEMA FIRM data where available (currently only available for coastal Rockingham County communities)

 2-foot contour elevation lines (See page 5 for more details)

 Tax parcel boundaries for many communities in the state

 Sea level rise scenarios along the coast You can easily turn on and off different map layers, zoom to locations by typing in an address, and measure distances in the viewer.

There is also a ‘Swipe’ tool that allows you to easily compare different map layers (for example, preliminary and effective flood hazard boundaries) in a particular location. This viewer includes information for all areas of the state that have digitally produced FEMA flood hazard information (i.e., all areas of the state except for Belknap County communities—sorry, guys!)
