Map Elevation Certificates

Map Feature


We've added a map to your CRS dashboard to assist you with flood information requests and elevation certificate management. To navigate to this new feature, just click Map in the dark blue sidebar.

Your map currently has four data layers that can be turned on or off using the blue toggle switch:

Flood Zones

Zones X (shaded), AE, AO, AH, A, VE, and D are contained in this map layer, differentiated by color. Where applicable, zone BFEs and/or depths are displayed on the map.


The Coastal Barrier Resources System (CBRS) boundaries are included, along with the 20 ft CBRS buffer zones.


Your uploaded Elevation Certificates are now automatically displayed on the map as orange points. When zoomed out, Elevation Certificates that are either very close to one another or assigned to a single property are clustered under a larger icon displaying the number of ECs at the location. To get a closer look, either zoom in or click on the cluster for automatic zoom.

Land Information

The Land Information layer contains topographic contour lines for the map. Contour intervals are depicted directly on the contour lines in meters.

Address Details

For address-specific data, click on an EC point or use the search bar (titled Search for address) in the upper right hand corner.


An information window will appear with the following information:

  • Address
  • Flood Zone
  • BFE
  • Datum
  • FIRM Panel
  • FIRM Effective Date
  • Initial FIRM Date
  • CBRS

If the address has one or more associated Elevation Certificates, they will appear under Elevation Certificates in the window. Listed ECs are links, clicking on them will open the associated PDF in a new tab.

The information contained in the Address Detail window is given for a geocoded point, and should not be used as an official determination.
