Stoneybrook Tributary Stream Restoration


As a part of the County's effort to help reduce sediment input which pollutes our streams and enhance aquatic habitat, the County has initiated a Stream Restoration project. Approximately 5,400 linear ft. of the Stoneybrook tributary between Strathmore Ave. and Rock Creek has been designated for restoration. This area was identified in the Rock Creek Watershed Feasibility Study (2001) as a priority for restoration.

Residents can also participate in the County's RainScapes Rewards program to install rain gardens, rain barrels, and other attractive stormwater management features on their property  to help reduce pollution. The cost of installation can be partially rebated by the County through the program. The application for the RainScapes Rewards program is available online.

Various public events will be held throughout the project phases for residents to learn about the project and to provide input on the design of the project. Check out the Project Schedule at the bottom of the page for more information!
