Project Background

Lafayette Village is facing significant erosion and sediment influx primarily due to increased surface runoff in its urban stream. With this project, the County intends to quantify Stream Sediment Erosion Rate and Nutrient Loading, and to understand Stream Restoration Efficiency.

Project Description

The project goals include:

• Reduce nutrient transport downstream to support overall watershed goals of improving water quality and functions.
• Retrofit the existing stormwater detention basin through a constructed wetland.
• Protect and improve bed form diversity, aquatic and riparian health.
   

Project Location

The proposed project is located within the vicinity of Mt. Airey Lane in Annandale in Accotink Creek watershed.

Project Phase

The project is currently in the design phase. 

Timeline

The design phase is estimated to be finished in Summer 2027 followed by construction.

Project Cost and Funding Source

The study and design of the Lafayette Village Sec 1 Stream Restoration is estimated to cost approximately $2.4 million. Funding for construction is dependent upon future budget availability and allocations. Stormwater projects are funded through the county Stormwater Service District.
