Title: Baltimore City, Maryland: Access Structures 2022

Geospatial_Data_Presentation_Form: vector digital data

Description:

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. Baltimore City was processed in 2022 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.

Use_Constraints:

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.

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, 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.

Enumerated_Domain:

Enumerated_Domain_Value: Dock / Pier

Enumerated_Domain_Value_Definition:

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.

Enumerated_Domain:

Enumerated_Domain_Value: Dilapidated Dock

Enumerated_Domain_Value_Definition:

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.

Enumerated_Domain:

Enumerated_Domain_Value: Private Ramp

Enumerated_Domain_Value_Definition:

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

Enumerated_Domain_Value: Boathouse

Enumerated_Domain_Value_Definition:

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.

Enumerated_Domain_Value: Community Dock

Enumerated_Domain_Value_Definition:

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.
