Section I: Funding Opportunity Description


The Lynnhaven River, Virginia, is the southernmost tributary of the Chesapeake Bay. Its watershed lies mostly within the bounds of the heavily urbanized City of Virginia Beach. The river once held an extensive network of intertidal and subtidal oyster reefs, but today the only subtidal reefs are those constructed as part of a river-wide restoration effort. Recently, as part of the Lynnhaven River Basin Ecosystem Restoration Project (LRBER), a joint USACE/City of Virginia Beach led effort, a large network of reef balls and a series of high-relief granite/crushed concrete reefs have been constructed in the Lynnhaven River system.  The intent of these reefs are dual-purpose oyster and fish reefs.  Many fish species in Chesapeake Bay prefer, and some require, hard reef habitat in order to thrive. This habitat type is rare in the modern-day Bay and was extirpated from the Lynnhaven River decades ago. These dual-purpose oyster/fish reefs are the first of their kind, constructed as part of a large-scale ecosystem restoration project in Chesapeake Bay.

Brief Description of Anticipated Work:

Our objectives are to monitor and document the status of these reefs. For the oyster component, a physical assessment of the reefs is desired. Assessing the reefs for oyster and other attached fauna for density and biomass (dry weight) and for oysters, size-frequency distribution. Approximately 50 samples will be needed to minimize the SE (standard error of the mean) and ensure survey accuracy.

An assessment of fish use of the reefs is also desired. For this component, a variety of methods could be used. Control sites for this work will also be necessary in order to determine what differences in fish species distribution and abundance, if any, exists between the fish/oyster reef sites and surrounding open sandy bottom areas.

There are two sites that will need to be monitored. The first site is 8-acres mostly in the low intertidal and shallow water zone. It consists of several thousand reef balls weighing approximately 50 lbs. Each. The second site which is currently  under construction  is  proposed to consist of crushed concrete  or  granite riprap with an oyster shell veneer. This subtidal, high-relief reef is approximately 18” off the surrounding bottom. The second site will cover anywhere from 23-30 acres post-construction and is approximately -6 ft MLW.

Public Benefit:

This large-scale ecosystem restoration project taking place within a heavily urbanized estuarine river system is of considerable interest to the public. It could potentially serve as a model for restoration in urbanized estuaries in other regions. It is one of the larger ecosystem restoration projects attempted in the Chesapeake Bay region. Assessing the progress of the largest component of this project, the dual- purpose fish/oyster reefs, is necessary to determine their effectiveness as well as are they providing ecosystem benefits sufficient to justify their cost. The reefs will improve local production of commercially and recreationally valuable fished species, such as blue crabs, black sea bass, and tautog, among others. Oysters can also be a net reducer of CO2, helping to reduce climate change impacts due to increased atmospheric CO2 from burning fossil fuels.

The results of this study shall also be published in a peer-review journal in collaboration with Norfolk District personnel, to provide the information gathered in the proposed study to the wider scientific community.

Section II: Award Information

Responses to this Request for Statements of Interest will be used to identify potential investigators for studies to be sponsored by the Norfolk District and the Engineer Research and Development Center to provide monitoring of these dual-purpose fish/oyster reefs. The estimated level of funding for FY22-23 is approximately $75,000.00. There are option years for two additional years, with each option year also providing for $75,000.00 to continue the monitoring as needed, for a total award of $225,000.00.

Government Involvement:

USACE personnel will assist in experimental design, provide maps of sites and desired sampling locations of the reefs, consult with the awardee on the specific proposed methodology to assess fish use, assist in production of a report that will also be published in a peer-reviewed science journal. USACE personnel will be co-authors on any peer-review articles that are produced from this study, assisting in writing, as well as approving the document for publication.
