{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 1, "name": "Chesapeake Bay Critical Area Towns", "type": "Feature Layer", "description": "This data set represents the Department of Natural Resources interpretation of the location, land cover/land use type and geographic extent of the critical land areas for towns near the Chesapeake Bay. A Critical Area includes all land within 1,000 feet of tidal waters and wetlands in Maryland, as well as the waters of Marylands Chesapeake Bay and coastal bay area. This data file Critical Areas Towns only contains Critical Areas in 14 Maryland Towns: Charlestown, Chesapeake City, Crisfield, Leonardtown, North Beach, Northeast, Perryville, Port Deposit, Princess Anne, Rock Hall, Salisbury, Secretary, Snow Hill and Vienna.There were many parties involved in producing Maryland's Critical Area data and the key parties will be listed. Each county and city (listed below) produced a hard copy map and submitted the map to the Chesapeake Bay Critical Area Commission (CBCAC) for approval. Through Coastal Zone Management grants, CBCAC digitized the county data. Maryland DNR's Chesapeake and Coastal Watershed Service finalized the data and is handling data distribution. Anne Arundel County, Office of Planning and Code Enforcement., Baltimore City, Department of Planning., Baltimore County, Department of Environmental Protection and Resource Management., Caroline County, Economic Development Commission., Calvert County, Department of Planning and Zoning (digital data not included)., Cecil County, Office of Planning and Zoning., Charles County, Department of Planning and Zoning., Dorchester County, Planning and Zoning Office., Harford County, Department of Planning and Zoning., Kent County, County Planning Commission., Prince George's County, Department of Environmental Resources., Queen Anne's County, Office of Planning and Zoning., St. Mary's County, Department of Planning and Zoning., Somerset County, Department of Technical and Community Services., Talbot County, Office of Planning and Zoning., Wicomico County, Office of Planning and Zoning., and Worcester County, Office of Planning, Permits and Inspections.Data Updated 09/15/2021.
