Great Wicomico Oyster Restoration: Solicitation for Construction Contract released
The solicitation for the construction contract of the Chesapeake Bay Oyster Program, Great Wicomico Oyster Restoration project, has been released and is now available on www.fbo.gov. Between 2003 and 2004, the U.S. Army Corps of Engineers built 85 acres of oyster reefs in the Great Wicomico River. Today, a portion of those reefs are not successful because either the reefs are too low, which allows sediment to cover the structures, or they have been damaged due to poaching. The goal of this project is to increase reef height, which will improve the conditions for oyster colonization and allow the reefs to become successful. Construction will include dredging of fossil shell from Tribell Shoals in the James River, the transportation of that shell to the Great Wicomico River, and the placement of the shell onto more than 11 acres of existing reefs.
Piankatank Oyster Restoration: Draft Environmental Assessment available for public review
A Draft Environmental Assessment (EA), with Appendices, for the Chesapeake Bay Native Oyster Restoration Project, Piankatank River, Virginia, is now available for public review. The purpose of this project is to increase the population of native oysters in the lower Piankatank River by constructing new oyster reefs. The public review period will last 30 days, ending on March 7, 2015. To submit comments pertaining to the documents, please contact: U.S. Army Corps of Engineers, Norfolk District, Planning and Policy Branch, Ms. Janet Cote, 803 Front Street, Norfolk, Virginia 23510 or via email at PROR@usace.army.mil.
The purpose of the Chesapeake Bay Oyster Restoration projects are to restore oyster habitat and populations in 20 tributaries of the Chesapeake Bay by 2025 as established in Executive Order 13508. To achieve this goal, oyster habitat must be protected and restored, and populations of oysters must increase substantially.
The Norfolk District, U.S. Army Corps of Engineers conducts three initiatives relating to the presence of oysters in the Chesapeake Bay:
• Construct projects designed to establish sustainable breeding populations of native oysters in sanctuaries in Virginia.
• Create a joint Norfolk District-Baltimore District Chesapeake Bay Oyster Restoration Master Plan to outline a long-term plan for large-scale native oyster restoration.
• Prepare an oyster environmental impact statement (EIS) that will evaluate ongoing native restoration efforts and the possible introduction of a non-native oyster species.
The Corps’ Chesapeake Bay Oyster Restoration program was authorized by section 704(b) of the Water Resources Development Act (WRDA) of 1986, as amended by Section 342. The program was formulated based on coordination and consultation among many project partners and stakeholders, federal and state resource agencies, watermen, the Chesapeake Bay Foundation, the academic community and interested citizens, as well as non-profit groups such as Oyster Recovery Partnership, Virginia Seafood Council, Lynnhaven River Now and others.
When Captain John Smith arrived with the first English settlers to the New World in 1607, he noted that oysters were so ubiquitous in the Chesapeake Bay (a name translated from the Native American words for “great shellfish bay”) that they lay “as thick as stones.” As recently as 100 years ago, huge oyster reefs posed navigational hazards to ships in the area. These historic populations, dubbed “Chesapeake Gold” by watermen, not only supported a booming oyster industry in Virginia and Maryland, but served the ecosystem by filtering water in the Bay and providing habitat and food for other creatures.
Oyster populations in the Chesapeake Bay have experienced a severe decline, beginning in the late 1800’s. Today, oyster population levels and biomass are less than 1 percent of historic levels. This decline has been primarily due to overharvesting, parasitic diseases, and loss of habitat.
Oysters are a keystone species in the Chesapeake Bay ecosystem. Oysters are filter feeders and have the potential to significantly increase water quality by removing suspended solids, organic particles, and phytoplankton from the water, which directly increases water clarity and quality. They also provide important structure and habitat in the form of oyster reefs, which attract a wide variety of fish species and other aquatic life.
The U.S. Army Corps of Engineers has been actively involved in oyster restoration in the Chesapeake Bay since 1996. Since 2001, sanctuaries have been constructed in the Rappahannock River, Tangier/Pocomoke Sound, Great Wicomico River, and the Lynnhaven River.
On-going and upcoming efforts include surveying of fossil shell resources, modeling to determine the environmental benefits of rotational harvest management regimes, monitoring of previously constructed oyster reefs, rehabilitation of existing reefs in the Great Wicomico, and pre-construction activities for oyster restoration in other Virginia tributaries.
The Corps mission is the ecological restoration of the oyster and is focused on increasing the population of native (Crassostrea virginica) oysters. As a result, the project will focus on restoring oysters in sanctuaries that are free from fishing.
The oyster restoration plan includes the creation of new oyster reefs, rehabilitation of non-productive reefs, development of seed-producing reefs, planting of disease-resistant seed oysters, and follow-on project monitoring. The use of disease -esistant strains of the native oyster such as DEBY, Crossbred, and possibly other disease-resistant varieties of the native species will be used, such as field-selected wild Lynnhaven River oysters.
The Norfolk District became involved with the program in 2001 and has completed three projects: the Rappahannock River, Tangier/Pocomoke Sound and the Great Wicomico River, as well as the first phase of a construction effort in the Lynnhaven River.
Authorized by Congress each year.
The schedule is based on funding.
