Description: In late 2018, MDP embarked on an update of the Statewide Generalized Zoning dataset, which prior to that was most recently updated in 2010. The update included changes to the methodology, generalized zoning categories, new spatial data, and updated summary tables. The new zoning categories shifted the Resource Protection categories to Rural zoning classes. Many of the other changes were implemented to enable MDP to update and enhance its ability to complete state, regional, and local development capacity analyses. The 2021 generalized zoning data was collected directly from counties and municipalities and received little processing to incorporate the data into a single dataset. After aggregating and generalizing, jurisdictions were invited to review and provide feedback on the generalized zoning tables in 2021 and the generalized zoning map in 2022.Generalized zoning data is not meant to substitute for local zoning information and should not be used to determine permissible uses or other potential development of a specific property. For information on local zoning, contact the local zoning office for the county or municipality in which you are interested. Fields include:Generalized Zoning (String, 30) – Generalized zoning based on MDP generalized zoning categories and dwelling units per acre as described by a zoning ordinance. Generalized Zoning Categories (String, 255) – Link to Maryland Department of Planning Generalized Zoning Categories (word document). Jurisdiction Code (String, 4) – Four letter county code: ALLE (Allegany), ANNE (Anne Arundel), BACI (Baltimore City), BACO (Baltimore County), CALV (Calvert), CARO (Caroline), CARR (Carroll), CECI (Cecil), CHAR (Charles), DORC (Dorchester), FRED (Frederick), GARR (Garrett), HARF (Harford), HOWA (Howard), KENT (Kent), MONT (Montgomery), PRIN (Prince George’s) QUEE (Queen Anne’s), SOME (Somerset), STMA (St. Mary’s), TALB (Talbot), WASH (Washington), WICO (Wicomico), WORC (Worcester). MUNICIPALITY_NAME (String, 50) – Name of municipality if zoning is municipal. A blank value ' ' means zoning comes from the county zoning.UPDATEYR (String, 10) – Date (YYYYMMDD) of when MDP collected the generalized zoning data from the local jurisdiction. It should be noted that this is not necessarily the same date as when the local government updated its zoning map. If the month or day is unknown, the date is YYYY0000.SOURCE (String, 255) - Link to more information.
