Flood Plain Overlay
Subsequent to the Board of Supervisors’ unanimous adoption of ZOAM-2015-0003, Floodplain Overlay District (FOD), on December 2, 2015, the county received comments from the Federal Emergency Management Agency (FEMA) identifying several remaining inconsistencies between FEMA's requirements and the county’s FOD regulations. Members of the Loudoun County staff have been working with the Facilities Standards Manual – Public Review Committee (FSM-PRC) to address those comments along with the recommendation of the Zoning Ordinance Action Group (ZOAG) to allow additional stormwater management uses in the FOD-Major Floodplain.

At the Board’s May 3, 2016, business meeting, the Board voted unanimously to direct staff to proceed with amendments to the FOD regulations in the Revised 1993 Loudoun County Zoning Ordinance (“Zoning Ordinance”) to add the following stormwater management Best Management Practices (BMPs) as permitted uses in the FOD – Major Floodplain: 1) rooftop disconnection; 2) sheetflow to conservation area or a vegetated filter; 3) grass channel; and 4) soil amendment; and to process the amendments concurrently with other amendments to the Zoning Ordinance and Facilities Standards Manual that are necessary to address comments from FEMA.

This item proposes the adoption of a Resolution of Intent to Amend the Zoning Ordinance to address the comments received from FEMA and to add the specific stormwater management BMPs identified above as permitted uses in the FOD-Major Floodplain. This Item also proposes a Resolution of Intent to Amend the County’s Facilities Standards Manual to conform with the proposed and adopted changes to the FOD.

The item prepared for the meeting and the Copy Teste ( a summary of the Board's action) are online:
