<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970s to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each of the Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. The techniques developed for Virginia's shoreline are used to create similar reports for the Maryland shoreline. Data collected describes conditions in the immediate riparian zone, the bank, and along the shore.</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV>

Structures that allow access to the water. Access structure types: Dock, Dilapidated Dock, Boathouse, Private Ramp and Public Ramp and Community Dock.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Dock / Pier
In this survey, a dock or pier is a structure, generally constructed of wood, which is built perpendicular or parallel to the shore. These are typical on private property, particularly residential areas. However, there are exceptions where they are used in working waterfront communities, and may be disconnected from the shore. In general docks provide access to the water, a mooring for vessels, and a venue for recreational activities. They are mapped as point features. Pier length is not surveyed.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Dilapidated Dock
A pier which has failed due to deterioration from age or storm damage is classified as a dilapidated pier. The remnants of this structure may be originaly pilings only.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Private Ramp
Boat ramps are used to launch vessels of all types. They are usually constructed of concrete, but wood and gravel ramps are also found. Point identification of boat ramps does not discriminate based on type, size, material, or quality of the launch. This inventory attempts to distinguish, when possible, private versus public ramps. Ramps located in privately owned, commercial marinas and residential communities are classified as private
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Public Ramp
Boat ramps are used to launch vessels of all types. They are usually constructed of concrete, but wood and gravel ramps are also found. Point identification of boat ramps does not discriminate based on type, size, material, or quality of the launch. This inventory attempts to distinguish, when possible, private versus public ramps. Ramps located in privately owned, commercial marinas and residential communities are classified as private.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Boathouse
boathouse is considered any covered structure alongside a dock or pier built to cover a boat. They include true “houses” for boats with roof and siding, as well as awnings that offer only overhead protection. Since nearly all boathouses have adjoining piers, piers are not surveyed separately, but are assumed. Boathouses may be difficult to see in aerial photography.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Community Dock
In this survey, a dock or pier is a structure, generally constructed of wood, which is built perpendicular or parallel to the shore. These are typical on private property, particularly residential areas. However, there are exceptions where they are used in working waterfront communities, and may be disconnected from the shore. Community Piers are commonly longer piers with fewer than 50 slips located in a residential development. Community piers with more than 50 slips are coded as a line feature (see Marina definition). In general docks provide access to the water, a mooring for vessels, and a venue for recreational activities. They are mapped as point features. Pier length is not surveyed.

The shoreline used for this county is the NOAA Continually Updated Shoreline Product (CUSP) and if necessary modified to reflect the land-water interface (shoreline) based on the latest imagery available.
2023-01-16T00:00:00
All processing steps for the shoreline inventory were generated using ArcGIS - ArcMap v10.6.1 while viewing conditions observed on MD_SixInchImagery and Google Earth Pro (checking dates from 1994 to 2018). For the land use/bank cover shapefile, arcs were split and coded for selected land use, bank height, tree fringe, and presence or absence of spit , marsh and beach. For the access structure shapefile, points were placed where structures (dock, dilapidated dock, boathouse, public ramp, community dock and private ramp) are located on the shoreline. For the shoreline structure shapefile, arcs were coded for bulkhead, dilapidated bulkhead, riprap, unconventional, debris, wharf, breakwater, groinfield, jetty, marsh toe revetment, and marina >50 slips and <50 slips.
