Stream restoration helps a waterfront city provide its community with cleaner water, wildlife habitat, and the socioeconomic benefits of a safe natural area within a former industrial site.
Cannery Park, located in the City of Cambridge, Maryland, is part of a significant revitalization project of Maryland’s eastern shore. Located on the former campus of the historic Phillips Packing Company-once the largest produce cannery in the U.S.-the 6.6-acre park is envisioned as a community gathering place that celebrates the unique character and heritage of Cambridge and Dorchester County. The revitalization is being implemented by a partnership that includes the City of Cambridge, Dorchester County, Maryland Department of Natural Resources (DNR), and the Eastern Shore Land Conservancy.
Biohabitats is leading the design and construction of a key component of the park project: the restoration of Cambridge Creek, a partially piped stream that flows through the park. Funded by a grant from the Maryland DNR Chesapeake & Atlantic Coastal Bays Trust Fund, the restoration aims to reduce sediment and nutrients flowing into the Chesapeake Bay. The project involves daylighting a 750-section of piped stream and restoring a highly-confined, 900-foot, tidally influenced section of the exposed stream.
The approach for the daylighted section, which is stormwater-dominated and non-tidal, is to raise the channel invert, increase habitat structure, and enhance the riparian forest. The daylighted channel will convey flows through a Regenerative Step Pool Storm Conveyance (SPSC or RSC) system consisting of a series of riffle structures and dissipation pools to help improve water quality. Two storm drain systems entering at the top of the RSC will be retrofitted with a bubbler outlet structure to attenuate peak flows entering the system.
The banks of the tidally-influenced section will be graded to maintain a tidal creek at low tide and create flat marsh benches to allow for the high tide to reach a much wider extent and support Spartina alterniflora.
The design also accommodates the additional stormwater flow projected to come from the future park development adjacent to the restoration site.
