Project Description

Prince George’s County Department of the Environment (DoE) partnered with GV-Petro Joint Venture, LLC (which is a joint venture of GreenVest, LLC and Petro Design Build, LLC) and Maryland-National Capital Parks & Planning Commission (M-NCPPC) to implement the Tinkers Creek Stream Restoration Project; an ambitious, innovative, and complex undertaking that stabilized eroding stream channels, re-connected the floodplain and its associated wetlands, improved habitat for terrestrial and aquatic species, and engaged a diverse community through outreach programs to enhance access to this valuable community amenity. The restoration of perennial, intermittent, and ephemeral stream reaches promoted stability and resiliency in both the stream resources and riparian buffers and delivered a suite of co-benefits including critical utility and infrastructure protection, public and private property stabilization, management of invasive plant species, and reductions in nuisance flooding. As one of the largest stream restoration projects in the State of Maryland at over 40,000 linear feet, this project reduces sediment loading to the Chesapeake Bay by over 4,000,000 pounds per year and represents a successful partnership between public and private entities and a success for the local community and Chesapeake Bay.

Woodend Nature Sanctuary Stream Restoration

Nature Forward, SMC and the Center for Watershed Protection worked together to design and construct a step pool system to stabilize a deeply incised stream bed at Woodend Nature Sanctuary in Chevy Chase, MD. The thoughtful design minimized tree loss and overall site disturbance, interrupted downstream pollution, restored base flow by connecting to the existing floodplain and enhanced in-stream and riparian wildlife habitat. The project improved public access and educational infrastructure for people of all abilities with a stormwater-permeable, wheelchair-accessible nature trail, a complex of accessible boardwalks around an in-line pond, and weirs that double as stream crossings.
