The Elizabeth River Project stored roughly 1,000 cubic yards, or about 30 truckloads, of shucked oyster shell in Chesapeake, Virginia. Now, these shells are part of a 1-acre oyster reef located in the Eastern Branch of the Elizabeth River, in a project funded by the National Fish & Wildlife Foundation.
The Eastern Branch oyster reef was constructed in two layers. On the bottom is a layer of crushed concrete, recycled from nearby buildings that were knocked down, followed by a layer of shells sourced from shucking houses in North Carolina. The Elizabeth River Project completed building its acre-sized oyster reef in June, but has a much larger goal of restoring 10 acres of native oysters by the year 2024. Using a National Oceanic & Atmospheric Association survey of the Eastern Branch, the Elizabeth River Project identified an additional eight acres for restoration and is now working on getting funding to continue their restoration work.
Along with creating the oyster reef, the Elizabeth River Project has also been busy building oyster “castles” along the branch’s shoreline. Oyster castles are stacks of concrete blocks that create suitable habitat for first-generation oysters. The height allows for oysters to attach without sinking into the mud, and since oysters prefer to attach to areas that already have oyster shells, the blocks typically contain about 30 percent shell.
The restoration projects in the Eastern Branch would not be possible without local partnerships, says Deputy Director of Restoration Joe Rieger. The Elizabeth River Project partnered with organizations such as Kinder Morgen to store and stockpile oyster shells, the Hampton Roads Sanitation District to turn waste concrete into oyster blocks and the Chesapeake Bay Foundation to eventually seed the area with baby oysters.
