Upper Watts Branch Forest Preserve Stream Restoration
Client: City of Rockville Dept. of Public Works
Location: Rockville, MD
Hazen and Sawyer, along with our design partner, Charles P. Johnson, assessed approximately 10,400 linear feet of the Upper Watts Branch Tributary to Watts Branch in Rockville, Maryland.
Project Outcomes and Benefits
- Identified stream restoration opportunities and storm drain outfall improvement locations.
- Quantified wetland functional uplift and sanitary sewer protection needs.
- Designed 2,066 feet of stream restoration, including repair of three failing stormwater outfalls and the protection of exposed sanitary assets, through an interactive public task-force process.
Hazen assessed storm drain and stream stability, developed concepts, and conducted public meetings. We prepared construction documents, specifications, cost opinions and provided construction management services. Hazen estimated the economic value of the Preserve’s existing streams and buffers, the maintenance costs associated with not stabilizing the worst erosion areas, and the economic value of re-storing environmental function within the impaired stream system. We also maximized the Chesapeake Bay nutrient credits generated by this project to help satisfy the City’s MS-4 requirements.
