<idAbs>&lt;DIV STYLE="text-align:Left;"&gt;&lt;DIV&gt;&lt;DIV&gt;&lt;P&gt;&lt;SPAN STYLE="font-size:12pt"&gt;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.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;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 (most recent MD Six Inch Imagery at time of inventory) . 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.&lt;/SPAN&gt;&lt;/P&gt;&lt;/DIV&gt;&lt;/DIV&gt;&lt;/DIV&gt;</idAbs>

<suppInfo>There are three shapefiles associated with the Maryland shoreline inventory database: Maryland_lubc_2020_2023 (land use and bank cover), Maryland_astru_2020_2023 (access points), and Maryland_sstru_2020_2023 (shoreline structures). MD_lubcMaryland_lubc_2020_2023 is a linear shapefile containing data about land use, tree fringe, bank height, and sandspit along the shoreline. Maryland_astru_2020_2023 is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Maryland_sstru_2020_2023 is a linear shapefile delineating hard structures in place at the shoreline (bulkhead, dilapidated bulkhead, riprap, wharf, unconventional, debris, marina &lt; 50 slips, marina &gt; 50 slips, jetty, marsh toe revetment, groinfield and breakwaters). </suppInfo>

<edomv>Dock / Pier</edomv>
<edomvd>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.</edomvd>

</edom>
<edom>
<edomv>Dilapidated Dock</edomv>
<edomvd>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.</edomvd>

</edom>
<edom>
<edomv>Private Ramp</edomv>
<edomvd>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</edomvd>

<edomv>Public Ramp</edomv>
<edomvd>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.

</edom>
<edom>
<edomv>Boathouse</edomv>
<edomvd>A 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.</edomvd>
<edomvds>VIMS Shoreline &amp; Tidal Marsh Inventory Glossary, Center for Coastal Resources Management</edomvds>
</edom>
<edom>
<edomv>Community Dock</edomv>
<edomvd>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. </edomvd>

<statement>Maryland Shoreline Inventories were completed over five years beginning in 2019 and ending in 2023. Inventories published in 2020: Anne Arundel County, Calvert County,, Dorchester County, Talbot County.
Inventories published in 2021: Charles County, St. Marys County, Somerset County, Worcester County.
Inventories published in 2022: Baltimore City, Baltimore County, Kent County, Queen Annes County, Wicomico County.
Inventories published in 2023: Caroline County, Cecil County, Harford County, Prince George County.</statement>
<prcStep>
<stepDesc>The shapefiles use a base shoreline from the NOAA Continually Updated Shoreline Product (CUSP) and if necessary modified to reflect the land-water interface (shoreline) based on the latest Maryland 6-inch imagery at the time of the inventory processing.
</stepDesc>
<stepDateTm>2016-07-13T00:00:00</stepDateTm>
</prcStep>
<prcStep>
<stepDesc>All processing steps for the shoreline inventory were generated using ArcGIS - ArcMap v10.6.1 or ArcPro v3.0.3 while viewing conditions observed on MD_SixInchImagery and Google Earth Pro (checking dates from 1994 to 2023). 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 sandspit , 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, dilapidated bulkhead, riprap, unconventional, debris, wharf, breakwater, groinfield, jetty, marsh toe revetment, and marina &gt;50 slips and &lt;50 slips.</stepDesc>
<stepDateTm>2020-02-04T00:00:00</stepDateTm>

<stepDesc>QAQC was done by a different Scientist and the entire shoreline was reviewed.
</stepDesc>
<stepDateTm>2020-02-18T00:00:00</stepDateTm>

<stepDesc>As the Shoreline Inventory for a Maryland locality is completed, it is added to this composite feature layer. This Shoreline Inventory represents data processed from 2020 to 2023.</stepDesc>
