Watts Branch is a 22 square mile watershed that drains into the Potomac River. The headwaters of Watts Branch, approximately 16 miles of stream, originate in the western half of the City of Rockville. Due to impacts of development and stormwater runoff, Watts Branch is experiencing increased erosion, which releases excess sediment and other pollutants that contribute to poor water quality in the stream, the Potomac River, and ultimately the Chesapeake Bay. In addition, this erosion threatens public infrastructure, trails and forest and wetland habitat. The Upper Watts Branch Park Forest Preserve Environment Restoration Project will enhance the Watts Branch watershed through stream restoration, stormwater management, wetland enhancement, reforestation and protection of public utilities.

The project was recommended in the (PDF) Watts Branch Watershed Study and Management Plan (PDF) as a crucial component to the long-term health of the watershed. It was also recommended

View the virtual tour by the Watts Branch Partnership and approved by the Mayor and Council. Staff has worked closely with the community on the project, including organizing a Citizens Task Force and field stream walks.

Location The project will take place within the Upper Watts Branch Forest Preserve Park and on City-owned parcels bounded between Gude Drive, Aster Boulevard, Nelson Street and Princeton Place. View the project limits.

Design change order #1 in the amount of $39,108 was approved on August 12, 2013 to perform additional stormwater analysis and field survey more areas of the park. Design change order #2 in the amount of $92,835 was approved by the Mayor and Council at their November 24, 2014 meeting to provide design and permitting services of addition areas in the park requiring environmental stabilization. The current total design contract is $419,943.
