Project Description:

Stream restoration is the re-establishment of the general structure, function and self-sustaining behavior of a stream system. Stream Restoration includes a broad range of measures including:

  • Removal of the watershed disturbances that are causing the stream to become unstable.
  • Installation of structures and vegetation to protect streambanks and provide habitat
  • Reshaping or replacement of unstable stream reaches into functional streams
  • 50% of the funding for this project comes from a Stormwater Local Assistance Fund (SLAF), which matches the remaining 50%, coming from the Stormwater Fund. The approximate cost and funding available at this time is $1.3 million. 

This project will be broken down into two phases:

  • Phase 1 will consist of approximately 600 linear feet of full restoration of the downstream section from the Chain Bridge Rd. Bridge west along the Rustfield and Taba Cove neighborhood property lines.
  • Phase 2 will consist of approximately 1,300 linear feet of full restoration upstream from Phase I, west behind the residential homes located along Springmann Dr. and Center St., to Keith Ave.

Benefits of Stream Restoration:

  • Prevent or minimize flooding
  • Protect and preserve natural floodplains
  • Improve and maintain ecological functions
  • Create and safeguard a healthy habitat for aquatic plants and animals
  • Channel the flow to prevent erosion of personal property
  • Improve groundwater recharge
  • Aesthetic improvements
  • Improve water quality by reducing sediment, nitrogen, phosphorus and other pollutant loads
    • City will receive removal credits towards the allocated Total Maximum Daily Loads (TMDL) assigned to the City streams and creeks

Location:

  • East side of Keith Ave. to the Chain Bridge Rd. bridge
