- Abstract:
-
The shoreline inventory files have been generated to support the application of the Maryland Shoreline Stabilization Model (SSM), developed by the Center for Coastal Resources Management (CCRM), Virginia Institute of Marine Science (VIMS), to enhance and streamline regulatory decision making in Maryland. This shoreline inventory includes the features needed as inputs to run the SSM. The data developed for the Shoreline Inventory is based on a three-tiered shoreline assessment approach. This assessment characterizes conditions by using observations made remotely at the desktop using high resolution imagery. Worcester County was processed in 2021 referencing the most recent available Six Inch resolution aerial imagery service for the State of Maryland. The three-tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, and natural protection (i.e., marshes and beaches); and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.
- Purpose: To inventory Maryland's tidal shoreline conditions.

These data should not be used for jurisdictional permit determinations beyond providing general shoreline condition or status information. These data have not been surveyed to property boundaries.The Comprehensive Coastal Inventory Program (CCI) at VIMS performs a service by distributing data generated by either CCI or public agencies which offer data without restriction or charge. CCI assumes no responsibility for data accuracy or precision, metadata completeness or correctness for digital information. CCI assumes no liability for misuse of any data which may arise as a result of any alteration, conversion, or combination with other data sources. As well, the timeliness and scale of these products must be considered when evaluating appropriate use.The contents of this dataset do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does the EPA endorse trade names or recommend the use of commercial products mentioned in this document.

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.

- Process_Description:
-
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, and private ramp) are located on the shoreline. For the shoreline structure shapefile, arcs were coded for bulkhead, delapidated bulkhead, riprap, unconventional, debris, wharf, breakwater, groinfield, jetty, marsh toe revetment, and marina >50 slips and <50 slips.
