<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>

Feature refers to a combination of land use in the immediate riparian area within 100 feet of the adjacent shoreline and best professional judgement when the infrastructure is setback on the parcel. Current land use: Commercial, Industrial, Paved, Marsh Island and NA.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Commercial
Commercial is a land use classification denoting small commercial operations such as shops, restaurants, as well as campgrounds. These operations are not necessarily water dependent businesses.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Industrial
Industrial operations are larger commercial businesses and can include areas where power plants, pulp mills, refineries, etc. are in operation along the coast.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Paved
Paved areas represent roads which run along the shore and generally are located at the top of the banks. Paved also includes parking areas such as parking at boat landing, or commercial facilities.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
Marsh Island
A marsh island is a vegetated wetland that is completely isolated from the mainland and found in open water. A marsh that is surrounded by water due to dissection from small tidal creeks was classifies as marsh, not marsh island.
VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management
NA
Indicates that these areas were not any of the above land use.

String

A narrow coastal landform tied to the upland shoreline at one end resulting from the deposition of sand moved by tides and currents. Spit features are generally sandy and may be dominated by beach, dune, and/or marsh habitats. For inventory purposes, this definition does not include spit features that are developed or have developable upland.

Beaches are persistent sandy shores that are visible during high tides. These features can be wide or thin lenses of sand. Beaches are coded as linear features at the wet/dry line to portray their location only. If a beach does not have a visible wet/dry line, then the line feature is located at the seaward edge of the beach. ‘Wide’ beaches have at least 25 feet of dry sand persistently visible above high tides. Beach features coded along tidal marsh shorelines are persistent, sandy features located on the water side of tidal marsh vegetation. Sand washed into tidal marshes is not coded as a beach if the marsh vegetation &/or marsh edge is still clearly visible. This classification of beaches along tidal marsh shorelines can include professional judgment.

When the dominant riparian land use is not Forest but a line of trees is maintained along the bank edge, the land use is noted to include a tree fringe. Wide tree fringe is over 100 feet.
Over 500 feet is coded as forest.

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.
2023-01-13T00:00:00
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.
