Project Update: June 2, 2021

Project Background and Description

The project includes the retrofit of two existing stormwater detention basins and restoration of approximately 1,600 linear feet of an unnamed tributary to Difficult Run. These stormwater management facilities were originally built more than 35 years ago along with the Leigh Meadow and Towlston Meadow subdivisions and are managed by Fairfax County. As part of regular operation and maintenance, county staff identified the dam embankment of one of the facilities and receiving stream were eroding affecting the function and safety of the facility.

These stormwater management facilities treat runoff from the community before it is discharged to the stream. The stream channel originates on private property and flows southwest until it enters a storm drain system that flows under Tuba Court. One basin (0584DP) is on Leigh Meadow homeowners association (HOA) property and another basin (0103DP), is on Towlston Meadow HOA property.

These facilities are being retrofitted to improve water quality and protect downstream properties. In addition, approximately 1,600 feet of stream channel will be restored. This is a high priority project due to the need to protect infrastructure, address the severity of erosion, the location of the channel in the headwaters of the Difficult Run Watershed, and the interest and support of the community.
