Project Background

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.

Project Description

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.
