<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The shoreline inventory files have been generated to support the application of the Living Shoreline Suitability Model (LSSM), 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 LSSM. </SPAN></P><P><SPAN>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 (MD Six Inch Imagery 2016/2017) . 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.</SPAN></P></DIV></DIV></DIV>

There are three shapefiles associated with the Maryland shoreline inventory database: MD_lubc (land use and bank cover), MD_astru (access points), and MD_sstru (shoreline structures). MD_lubc is a linear shapefile containing data about land use, tree fringe, bank height, bank cover, and spit along the shoreline. MD_astru is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. MD_sstru is a linear shapefile delineating hard structures in place at the shoreline (bulkhead, dilapidated bulkhead, riprap, wharf, unconventional, debris, marina < 50 slips, marina > 50 slips, jetty, marsh toe revetment, groinfield and breakwaters).
This project has been funded wholly or in part by the United States Environmental Protection Agency under assistance agreement CD-963623-01-1 to the Maryland Department of the Environment.

Comprehensive Coastal Inventory, Center for Coastal Resources Management
The shoreline used to create the shapefiles for Maryland is the dataset created in conjunction with the Chesapeake Bay Critical Area remapping project) This shoreline was published in 2016.
2016-11-04T00:00:00
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 land use, bank height, bank cover, 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.
2020-03-03T00:00:00
QAQC was done by a different Scientist and the entire of shoreline was reviewed.
2020-06-01T00:00:00
As the Shoreline Inventory for a Maryland locality is completed, it is added to this composite feature layer. This Shoreline Inventory represents data processed beginning in 2020.
