Data Management Plan (Deprecated)

These data represent state geographic location descriptions (GLDs). Section 307 of the Coastal Zone Management Act of 1972, called the "federal consistency" provision, provides states with review authority of federal actions in areas outside of the state coastal zone, which they otherwise would not have, for activities that may affect a state's coastal uses or resources. Federal license or permit, and federal financial assistance activities that are listed in state coastal management programs for an accompanying GLD are subject to state review. All listings and GLDs must be approved by NOAA.

Process Steps:

• 2017-01-01 00:00:00 - 1. Data sets for Oregon, Rhode Island, and New York provided by the respective state. These data sets were used as provided, except as noted below for Rhode Island. 2. For Connecticut: NMFS Statistical Areas: extracted the six respective areas from the "Statistical_Areas_2010_withNames" shapefile. Long Island Sound: Extracted the 12m bathy contour (40ft. equivalent) and manually closed the line (between 10m and 14m contours). Extracted the 6m bathy contour (20ft. equivalent) and manually closed the line (between 4m and 8m contours). Used RNCs to create these contours in far eastern Long Island Sound, where the LIS contours in the source data were not included. Off of Montauk Point (eastern point of Long Island), the 12m contour was extended to the New York-Rhode Island border by a line extending from the furthest point east of the 12m contour, to the New York-Connecticut boundary, following a bearing generally parallel to the New York state boundary that exists to the south of Long Island. Fishers Island Sound: the geometry (in New York waters) was extracted from the "NAMED_WATERBODY_POLY" shapefile. Byram River: the geometry (in New York waters) was extracted from the "pwl" shapefile, excluding Kirby Pond. Little Narraganset Bay: the geometry (in Rhode Island Waters) was extracted from the Connecticut state boundary and the Rhode Island shoreline. Connecticut River: used Massachusettss "CENSUS2010HYDRO_SHP" feature class and manually extracted the river (below the dam in Holyoke, MA). 3. For Delaware, acquired supporting maps illustrating the GLD, via email from Delaware CMP. Using these maps and textual descriptions, extracted the necessary offshore lease blocks for the federal waters portion of the GLD. Clipped the seaward extent of these lease blocks with the 24NM line. The remainder of the offshore alternative energy portions of the GLD (in state waters) were extracted using a combination of the Submerged Lands Act's seaward boundary, a national shoreline, the OCS Administrative Boundaries, and COLREGS demarcation lines. The segments of the Delaware River/Bay were constructed using a combination of official state boundaries, maintained channels in Delaware Bay, a boundary of the Delaware Bay (excluding tributaries) from the New Jersey Department of GIS, and the RNCs (i.e. Commodore Barry Bridge). The non-native shellfish segment in the Chesapeake Bay was extracted from a combination of official state boundaries, a national shoreline, and COLREGS demarcation lines. Used centerline of the navigation channel in Delaware Bay to establish the Delaware-New Jersey boundary necessary for the creation of the GLDs for both states. This was suggested by Delaware, since no official boundary between these states in Delaware Bay had ever been agreed upon. 4. For New Jersey, the segments of the Delaware River/Bay were constructed using a combination of official state boundaries, a national shoreline, and COLREGS demarcation lines. Used centerline of the navigation channel in Delaware Bay to establish the Delaware-New Jersey boundary necessary for the creation of the GLDs for both states. This was suggested by Delaware, since no official boundary between these states in Delaware Bay had ever been agreed upon. 5. For Pennsylvania, the boundary was constructed using a combination of official state boundaries, a state of Ohio shoreline, and Office for Coast Survey's US-Canada border. The western portion of the boundary was constructed using a line that was parallel to the Pennsylvania-Ohio border at the origin of the GLD's southeast boundary. 6. For Rhode Island, erased the Ocean SAMP boundary with the Submerged Lands Act (SLA) seaward boundary, as directed by the state CRMC office. 7. For Texas, the Western GOM and Central GOM "BOEM Oil and Gas Planning Areas" features were extracted. These constitute the limit of the Texas GLD, as confirmed by the Texas General Land Office. 8. Added fields and populated according to data dictionary
• 2019-06-13 00:00:00 - 1. Download amended Rhode Island shapefile from NROC and the national GLD layer from Marine Cadastre. 2. Merge amended GLD to the national data set and populate attributes based on information for the Rhode Island CRMC. 3. Update metadata.
• 2022-04-01 00:00:00 - 1. Modified field names to better reflect the content per field. 2. Modified the symbology to illustrate state jurisdiction per feature.
• 2024-02-01 00:00:00 - 1. Acquire the new textual description from New York Department of State and update geometry using sources mentioned in the description. Sources included coordinates, the 70-meter bathymetric contour, the Submerged Lands Act boundary, OCS lease blocks, NMFS statistical areas, and vessel routing measures (Barnegat to Ambrose Traffic Lane). 2. Amend new feature to national data set and populate attributes accordingly. 3. Change the length of the "geographicLocationDescription" field from 1,664 characters to 4,096 characters. 4. Check geometry and repair as needed.
