St. Luke’s Eastport – Restoration of Nature
The Alliance for the Chesapeake Bay, along with our partners, will restore a historic stream, wetlands, and woodlands along St. Luke’s property to create clean water and quality habitat while mitigating a 28 acre municipal stormwater pipe system polluting Back Creek in Eastport, Annapolis.
We will use a treatment train of best management practices that includes: curb cuts for bioswales, the construction of a regenerative stream channel, living shoreline, tidal marsh habitat restoration, and a planned partial mitigation of 2 additional private property stormwater drains emptying into the cove just past the Regenerative Stormwater Conveyances (RSC) tidal interface. The RSC approach attempts to restore ecosystem balance with natural form and energy profile of a forested stream and wetland complex.
A stream that currently flows through underground pipes will be re-established by daylighting stormwater pipes, allowing the water to enter a series of step pools and weirs that naturally convey stormwater while slowing it down and spreading it out. This will allow the replenishment of the aquifer through infiltration, while also treating the water as it flows and seeps through the stream channel and re-established balanced ecosystem. At the tidal interface, the project, will tie in more BMPs by re-establishing native tidal marsh habitat and living shoreline on Watergate Pointe’s property furthering improving water quality while stabilizing eroding banks.
The project is enabled by two grant awards from Maryland’s Chesapeake and Atlantic Coastal Bays Trust Fund totaling $1,115,770.
The expected annual nutrient reductions for the RSC are: total nitrogen – 200.14 lbs, total phosphorus – 36.40 lbs, and total suspended solids – 22 tons. Additionally, there will be a planned educational campus to inspire stewardship and help school children meet environmental literacy requirements.
There are many benefits to this project. The resulting clean water and quality habitat will enable spawning fish and other aquatic species to thrive. Overall restoration will provide food and shelter for flora and fauna. Reduced pollution will benefit the City of Annapolis and will provide significant Total Maximum Daily Load (TMDL) reduction credits to help meet the Chesapeake Bay Program’s blueprint for restoration. And finally, quality green space for the community will be created in a park-like setting, which doubles as an environmental education campus for public and private schools in teaching environmental literacy.
