Grosvenor Luxmanor Tributary Stream Restoration
This project started construction in February 2025 and is expected to be completed in June 2026. A portion of the project on M-NCPPC property was completed by Montgomery County Parks in 2022 (see map below) .
This project is part of the Montgomery County’s ongoing effort to restore degraded streams, enhance aquatic habitat and reduce pollution caused by stream erosion in our local streams and the Chesapeake Bay. The Department of Environmental Protection (DEP) has collaborated with the Maryland-National Park and Planning Commission (M-NCPPC), the State Highway Administration (SHA) and local residents to develop this Stream Restoration project.
Approximately 5,982 linear feet of the Grosvenor/Luxmanor Tributary and the Rudyard Drive Tributary will be restored.
Various public events were held throughout the planning phases of the project to allow residents to learn about and provide input on the project design. As construction of the project progresses dates on the project map below will be updated to indicate when each project segment will be in construction.

How Can I Help?
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.
