The Fairview-Valley Avenue neighborhood flooded due to an extreme rain event on July 8, 2019. A study was completed in August 2020 and evaluated the severity and potential causes of structural flooding at affected properties within the Dranesville and Providence Districts from the July 8, 2019, storm event. The study identified potential recommendations for further assessment and detailed design.
This neighborhood stormwater improvement project will evaluate existing drainage and stormwater infrastructure in the vicinity of Valley and Fairview Avenues and Cross Street. The site is located within a 115 acre drainage area that outfalls to Bryan Branch within the Pimmit Run Watershed. Existing stormwater infrastructure includes systems managed by Fairfax County and the Virginia Department of Transportation (VDOT) within the public right-of-way and easements on private residential lots.
The primary goals of the project are to mitigate structural flooding and improve resiliency of the drainage system.
The project is in the vicinity of Cross Street, Fairview and Valley Avenues to a culvert on Old Dominion Drive.
A final design will be developed based on the community and staff input received on the conceptual design.
Reduce frequent flooding
Convey stormwater safely through the neighborhood
Address structural flooding and public safety concerns
The project is the final design phase that will include securing the easements necessary to complete the project.
What to Expect
County staff will work with the community throughout the design process to arrive at the best possible solution to reduce flooding hazards within the project area.
Project cost and funding source
Design and construction of the Valley Avenue stormwater improvement project is estimated to cost $848,000. Stormwater projects are funded through the county Stormwater Service District. Construction is based on approval of future funding.
