Flood Insurance Rate Map: FEMA Risk Map Floodplain Remapping Project

Flood Insurance Rate Map and Flood Insurance Study


A Preliminary Flood Insurance Rate Map (FIRM) and a Revised Preliminary FIRM were produced by the Risk MAP (Risk Mapping, Assessment and Planning) project consultant for Loudoun County. Accompanying the Preliminary FIRM was the Preliminary Flood Insurance Study (FIS) report.
 

The initial data submission to the Federal Emergency Management Agency (FEMA) was dated May 23, 2014. Revisions, dated December 12, 2014, and February 23, 2015, were made to some sections (called panels) of the FIRM and submitted to FEMA. They were made available to the public as the best information known at the time of posting, but were for review and guidance purposes only and subject to change.

(See example of a FIRM panel at right.) Since the FIRM and FIS have been finalized, the preliminary information has been superseded. The current information is available here

To facilitate the public’s access to view the preliminary floodplain mapping results, county staff developed an online interactive floodplain mapping tool, which allows more convenient and detailed viewing at the parcel level of the latest mapping information compared to the county's current Floodplain Overlay District zoning layer.
