Living Shoreline Design Guidelines For Shore Protection In Virginia’S Estuarine Environment, C. Scott Hardaway Jr., Donna A. Milligan, Karen Duhring

Reports

The Chesapeake Bay has about 6.5 million people living in its coastal counties and much of the shoreline is privately-owned. For communities along the shore, the continual shore retreat may be a problem. When land along the shore show signs of erosion, property owners tend to address it.

These guidelines are meant to address the need to educate consultants, contractors, and other professionals in the use of living shoreline strategies. It provides the necessary information to determine where they are appropriate and what is involved in their design and construction. The guidelines focus on the use of created marsh fringes …

Data Collection At Fifteen Selected Creeks In Support Of Shallow Water Dredging On Virginia’S Middle Peninsula - Methods & Data Report, Nicholas J. Dinapoli, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox, Cameron Green, Scott Lerberg, Eduardo J. Miles, Alex Demeo, George Brooks

Reports

Federal funding has been historically available for the Army Corps of Engineers for shallow draft navigation projects. However, past and recent subsidies have not provided ample funding at levels to sustain maintenance dredging for the 17 federal navigation channels on the Middle Peninsula. Further, funding for maintenance of non-federal channels has been historically neglected by the Commonwealth of Virginia until the Virginia General Assembly established the Virginia Waterway Maintenance Fund in 2018. For the past decade the Middle Peninsula Chesapeake Bay Public Access Authority, the Middle Peninsula Planning District Commission and its member jurisdictions, and the Virginia Institute of Marine …

Leesylvania State Park Living Shoreline Project Monitoring Protocol, Donna A. Milligan, Walter I. Priest, C. Scott Hardaway Jr.

Reports

Leesylvania State Park is located along the Potomac River in Prince William County, Virginia (Figure 1). It is one of the most highly used state parks in Virginia with attendance topping 600,000 (Anne, 2017). The project shoreline occurs on the southeast-facing Potomac River shore north of the marina (Figure 2). This section of coast is very low and is exposed to long fetches across and down river. Prior to the project, the shoreline had a scarped bank, exposed tree roots, and falling trees which was unsafe for park visitors (Figure 3).

In 2011, the Shoreline Studies Program at the Virginia …

A Geotechnical Evaluation Of Chesapeake Beach Shoal For Beach Quality Sand, Donna A. Milligan, C. Scott Hardaway Jr., Mary C. Cox, Christine A. Wilcox

Reports

Chesapeake Beach Shoal is located along the southern coast of Chesapeake Bay in Virginia Beach, Virginia (Figure 1-1). Chesapeake Beach, which is nearly adjacent, has a history of chronic beach erosion which threatens upland infrastructure. Beach nourishment occurs on Ocean Park Beach to the east from intermittent dredging of Lynnhaven Inlet (Figure 1-2), but the effects do not always translate westward to Chesapeake Beach. The general alongshore sand movement is east to west. The purpose of this project is to establish a reliable source of beach sand for Chesapeake Beach via the nearshore shoal. Many issues, including identifying the location …

Encroachment Of Sills Onto State-Owned Bottom: Design Guidelines For Chesapeake Bay, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine A. Wilcox, Jian Shen, Carl H. Hobbs Iii

Reports

Recent efforts have sought to expand the use of “Living Shorelines” by waterfront property owners in Virginia and Maryland to combat tidal shoreline erosion. Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. Some regulatory agencies and non-governmental organizations prefer living shorelines over “traditional” shore hardening using bulkheads or stone revetments because these structures create a “barrier” or disconnect between the upland and marine environments. Typically, creation of a living shoreline involves the placement of sand, planting marsh flora, and, if necessary, …

Performance Of Sills: St. Mary’S City, St. Mary’S River, Maryland, C. Scott Hardaway Jr., W. G. Reay, Jian Shen, Scott Lerberg, Donna A. Milligan, Christine A. Wilcox, Kevin P. O'Brien

Reports

Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. A common living shoreline design in Chesapeake Bay includes a low offshore rock sill to absorb wave energy with an emergent wetland landward of the sill to enhance erosion control, provide critical habitat, and improve water quality condition. This study is part of a larger, ongoing project to (1) evaluate erosion control effectiveness and the sustainability of offshore sill and fringing marsh design and structure, (2) evaluate ecological services (e.g., habitat value, water …

A Survey Of The Effectiveness Of Existing Marsh Toe Protection Structures In Virginia, Karen Duhring, Thomas A. Barnard, Center For Coastal Resources Managment, C. Scott Hardaway Jr., Shoreline Studies Program

Reports

Using tidal marshes and other vegetated treatments for upland erosion control has been an accepted practice for years, yet the scientific understanding and established guidelines for this approach are limited. This survey was conducted to evaluate the efficacy of existing marsh toe protection structures, a particular type of erosion control treatment associated with tidal marshes on Chesapeake Bay shorelines. Field evaluations were conducted at 36 sites in 6 localities on the Middle Peninsula and Northern Neck of Virginia. General dimensions of each structure were recorded and observations made of erosion evidence, structural integrity, construction access impacts, and adjacent landscape settings. …

Dune Evolution Westmoreland County, Virginia Potomac River Shoreline, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Christine Wilcox, George R. Thomas, Kevin O'Brien

Reports

Shoreline evolution is the change in shore position through time. In fact, it is the material resistance of the coastal geologic underpinnings against the impinging hydrodynamic (and aerodynamic) forces. Along the shores of Chesapeake Bay, it is a process-response system. The processes at work include winds, waves, tides and currents, which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change but it is as important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed …

Jackson Creek Federal Navigation Project: Stove Point Placement Area Analysis Final Draft, Donna A. Milligan, C. Scott Hardaway Jr., George R . Thomas, Rebecca C.H. Brindley

Reports

The purpose of this study is to perform a shore assessment around Jackson Creek in order to determine what processes are affecting sedimentation in the creek mouth. In addition, the placement of sandy dredge material from Jackson Creek onto Stove Point also was to be determined. The Jackson Creek-Stove Point-Stingray Point evaluation includes an assessment of shore conditions and historic shore changes as well as a wave climate and sediment transport analysis. The product of this study is a recommendation as to the location of placement of dredge spoil for beach nourishment along the Stove Point Shoreline.

Bank Erosion Study, C. Scott Hardaway Jr., George R. Thomas, J. B. Glover, J. B. Smithson, Marcia Berman, A. K. Kenne

Reports

The Bank Erosion Study was designed to evaluate eroding fast land bank shorelines as contributors of sand, silt and clay and total nitrogen and total phosphorous introduced into the Chesapeake Bay estuarine system. In addition, the extent and effectiveness of erosion control measures were evaluated for selected shoreline reaches. Fastland banks are the uplands along the shorelines that are composed of semi-consolidated sediments. This study evaluates about 2000 miles of primary tidal shoreline in the Virginia portion of the Chesapeake Bay estuarine system for areas of fast land bank erosion. Primary tidal shorelines are those along the main stem of …
