Loudoun River and Stream Corridor Resources (RSCR)

River and Stream Corridor Resources (RSCR) is a part of the Natural and Environmental Resources chapter of the new Loudoun County Zoning Ordinance adopted on Dec 13, 2023. The River and Stream Corridor Resources is composed of the following areas; Floodplain Overlay District and Adjacent Steep Slopes (Resource Area Width), 50' Riparian Protection Buffer Width, and Variable Riparian Preservation Buffer Width (remaining area to meet either the 100' or 300' minimum stream buffer. The 300' minimum stream buffer applies to the County's Scenic Rivers (Goose Creek & Catoctin Stream), Potomac River, Bull Run and Broad Run. The 100' minimum stream buffer applies to all other rivers and streams located within the Floodplain Overlay District. The minimum stream buffer distances for the RSCR are measured out from the either both edges of the County's double line stream data or from the centerline of the single line stream data. In some cases, the additional 50' Riparian Protection Buffer to the Resource Area Width (Floodplain and steep slopes) may result in a total RSCR width that is greater than the 100' or 300' minimum stream buffer width. Refer to Chapter 6 of the Loudoun County Zoning Ordinance for additional tables and graphs describing the RSCR and list of Natural and Environmental Resources permitted and special exception uses in both the RSCR and steep slopes.
