<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Virginia Shoreline Inventory is a series of reports and data that describe the condition of tidal shorelines for individual localities in the Commonwealth of Virginia. This inventory series started with historic reports produced in the 1970’s. It also includes contemporary digital inventory updates generated from 1998 to the present using a combination of Geographic Information Systems (GIS), Global Positioning System (GPS), and remote sensing technology. One of the conditions described in the inventories is the spatial extent and distribution of hardened shoreline structures that are used for erosion control (i.e., revetment, sills, bulkheads, breakwaters, groins, unconventional, oyster structures, and dilapidated bulkheads), as well as living shoreline treatments (breakwater with beach nourishment, marsh with sill, marsh with oyster structures [oyster bags, manufactured, natural materials], constructed oyster reefs, and coir logs).</SPAN></P></DIV></DIV></DIV>
To inventory Virginia's tidal shoreline conditions.
This project has been funded wholly or in part by The Virginia Department of Environmental Quality, Virginia Coastal Zone Management Program Grant # NA24NOSX419C0026.

Shoreline were created using 2021 Virginia Base Mapping Program (VBMP) imagery at a scale of 1:1000 as a backdrop and using ArcGIS Pro 3.4.3. Using this as a baseline, the shoreline inventory was remotely generated using two sources: Google Earth imagery and high-resolution imagery available through Bing Maps. Shoreline structures were delineated under the categories of: revetment, bulkhead, breakwater, groin, unconventional, oyster structure, coir log, sill,and dilapidated bulkhead. A living shoreline field was added to identify living shorelines among the aforementioned structures and include: breakwaters with beach nourishment, marsh with sill, marsh with oyster structures: oyster bags, marsh with oyster structures: manufactured, constructed oyster reef, marsh with oyster structures: natural materials, and coir log. The structures were delineated as polylines.
Erosion Control Structures publish in 2024 and 2025 were appended into one combined layer.

Erosion control structures at the shoreline or in the nearshore environment: revetment, bulkhead, breakwater, groin, unconventional, oyster structure, coir log, sill and dilapidated bulkhead.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Breakwater
Breakwaters are structures that sit offshore below mean low water, and generally occur in a parallel series along the shore. Typically, breakwater systems include sand nourishment to create or enhance an existing beach. Breakwaters are distinguished from rock sills by the size of the structures, distance offshore, and presence of a sand beach instead of a tidal marsh landward from the structures. The classification can include best professional judgment.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Dilapidated Bulkhead
A bulkhead which has failed, is failing, due to deterioration from age or storm damage.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Groin
Vertical structures that sit perpendicular to the shore, generally placed from the uplands into the waterway. They can be constructed of rock, timber, concrete, or other material. They are frequently set in a series known as a groinfield, which may extend along a stretch of shoreline for some distance. A groin is mapped as one linear feature perpendicular to the shoreline.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Oyster Structure
Structures placed in the intertidal or subtidal zone upon which oysters will, or have, set.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Revetment
Sloped structures constructed with stone or other materials placed against the upland bank for erosion protection. Revetment is mapped as a linear feature along the shoreline.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Sill
A free-standing structure that is built to structurally withstand the weight of the material alone, independent of assistance from another structure. Placed parallel to and offshore of the feature that is intended to protect. Commonly built of rock.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Unconventional
A structural treatment, likely intended for erosion control, that does not fall into other structural categories. Examples of this include debris, rubble, tires, and other nonuniform materials. It may be a combination of materials including in a manner similar to riprap, bulkhead, and other shoreline protection structures.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Coir Log
Interwoven coconut or other natural fibers that are bound together with biodegradable netting.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Bulkhead
Vertical structures, generally built just seaward of the area to be protected and backfilled with fill material. They function like a retaining wall, as they are designed to retain upland soil, and prevent erosion of the bank from impinging waves. Bulkheads are traditionally built of treated wood, steel, vinyl or plastic. From aerial photography, long stretches of bulkheaded shoreline may be observed as an unnaturally straight or angular coast. They are mapped and illustrated as linear features along the shoreline. In rare cases, the mapped bulkhead location may be well inland from the depicted location because the coding follows a digital shoreline.

Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Breakwater with Beach Nourishment
Breakwater with beach are combination approaches of both structure and natural or nature-based feature, namely one or more breakwaters and an existing beach and/ or sand nourished beach.

Marsh with Sill
Planted or existing marsh with fronting sill structure.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Marsh with Oyster structures: manufactured
Structures that are made from manmade materials, such as concrete, that are placed on the water side of a created or existing marsh upon which oysters will, or have, set. Examples of these include reef balls, oyster castles, and oysterbreaks.
Glossary of Shoreline Features Defined, Center for Coastal Resources Management, VIMS 2024
Marsh with Oyster structures: natural materials
Structure that is created by placing loose stone or oyster shell placed within, or on the water side of a marsh upon which oysters will, or have, set. Typically installed as a low relief scattering of substrate.
