FEMA to Map Revision

The Department of Homeland Security’s Federal Emergency Management Agency (FEMA) has issued a notice for a pending Letter of Map Revision (LOMR) which reflects revised elevations for the flood event having a 1-percent chance of being equaled or exceeded in any given year (base flood). The proposed revisions include modification of Base Flood Elevations (BFE) in the tidal influenced areas of the Potomac River, Piscataway Creek, Broad Creek, Unnamed Tributary to Broad Creek and Oxon Run. This LOMR, in conjunction with effective flood hazard information which is unaffected by the subject map change, is the basis for the floodplain management measures which the County is required to either adopt or show evidence of being in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP).

Before this LOMR becomes effective for floodplain management purposes, FEMA must provide persons an opportunity to appeal the proposed information. Any interested party may request that FEMA reconsider this LOMR within 90-days of the February 20, 2018 public notice which appeared in the Washington Times newspaper. For information on the statutory 90-day period provided for appeals, please visit FEMA’s website at www.floodmaps.fema.gov/fhm/bfe_status/bfe_main.asp.

For questions or comments, please contact Dawn Hawkins-Nixon, P.E., Associate Director, Sustainability Division, DoE at or dhnixon@co.pg.md.us.

FEMA proposes to revise flood hazard information for portions of the Potomac River, Piscataway Creek, Broad Creek, an unnamed tributary to Broad Creek and Oxon Run. This revision reflects an increase in the base flood elevation (i.e. the elevation of the flood having a 1-percent chance of being equaled or exceeded in any given year) for the purpose of correcting an elevation which is shown on the current Flood Insurance Rate Map (FIRM) for Prince George's County.
