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.
Although the FIRM and FIS report were preliminary and not intended for technical use, they were useful for property owners and others to review the status of the floodplain mapping results at that phase of the process and identify if there may have been potential flood hazard issues related to existing or planned use of a specific property. At the time, the Preliminary FIRM and the FIS were available for viewing as FIRM "panels" on a FEMA web site and in hard copy at the Loudoun County Government Center. (See example of a FIRM panel at right.) County staff also developed an online web mapping program to facilitate viewing the information. Since the FIRM and FIS have been finalized, the preliminary information has been superseded.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 finalized 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.
