In 1993 - the Maryland Department of Planning and the Maryland State Highway Administration entered into a Data Base Usage Agreement with Bell Atlantic and Data Chromatics - Inc. to develop an enhanced street address map for Maryland. ZIP Code boundary area files were one of the products derived from this partnership. The resulting boundary area files were intended to improve the cartographic quality and accuracy of the ZIP code boundary area files derived from the U.S. Census Bureau's post 1990 Census TIGER\Line Files (based on the Census Bureau's ZIP code tabulation areas - ZCTAs). Subsequent iterative improvements to the ZIP Code boundary area files have been made using premise address information associated with mapped parcel records as provided in the Maryland Department of Planning's MdProperty View GIS tax map and parcel record DVD product. The resulting files are meant to serve as a good approximation"" of ZIP codes as polygons (which in reality they are not) but are not official ZIP Code maps and are not meant to be a substitute for any products offered by the U.S. Postal Service - the official source for ZIP code information. While there are no restrictions on their use we do recommend that they are best used with MdProperty View and that MDP makes no guarantee or warranty regarding the files.

In 1984 - the General Assembly enacted the Chesapeake Bay Critical Area Act to regulate development - manage land use and conserve natural resources on land in those areas designated as Critical Area. For this document - the Critical Area is all land and water areas within 1000 feet of the tidal waters' edge or from the landward edge of adjacent tidal wetlands and the lands under them. Georeferenced digital data files of the critical Area have been produced for Baltimore City and the 16 Maryland counties with land located within the Critical Area. The digital maps produced for each jurisdiction are polygons depicting the Critical Area and the land use classifications recognized by the Chesapeake Bay Critical Area Commission (CBCAC). Each jurisdiction is a separate file. The data were produced from hard copy parcel maps originally submitted by the counties as part of the requirements for developing their Critical Area Program. For the purpose of the Mdimap web service the Critical Area Data is displayed by two data layers - one general layer and one layer showing the available critical area data for local towns.Feature Service Link:https://mdgeodata.md.gov/imap/rest/services/Environment/MD_CriticalAreas/FeatureServer ADDITIONAL LICENSE TERMS: The Spatial Data and the information therein (collectively "the Data") is provided "as is" without warranty of any kind either expressed implied or statutory.

This GIS dataset contains growth tier maps adopted by local (county and municipal) jurisdictions under SB236. Data are generally collected from county and municipal jurisdictions by the Maryland Department of Planning (Planning) or digitized by Planning in coordination with local jurisdictions. For more information about SB236, see Planning’s Septics Law Implementation Website at https://planning.maryland.gov/Pages/OurWork/SB236Implementation.aspxThis document describes standard operating procedures for aggregating growth tier map GIS data. These procedures may not apply to historical data (i.e. records for which both the SRC_DATE and GIS_SRC fields are blank). For example, Planning may have realigned historical data from local jurisdictions to parcel polygon boundaries or used different procedures to represent municipal tiers when municipalities concurred with county tier maps.Planning generally requests updated GIS data once a jurisdiction notifies Planning that a growth tier map has been amended. Aggregated data may be outdated or incomplete if Planning has not yet received or processed GIS updates from jurisdictions. Planning generally does not alter geometries received from the local jurisdictions except to divide municipal tiers at the county boundary (see JURSCODE field description). This dataset may contain overlap where multiple jurisdictions designate tiers in the same area.Fields include:JURSCODE – MdProperty Viewjurisdiction code (four-letter county or Baltimore City code). For tiers designated by counties, this is the jurisdiction responsible for designating the growth tier. For tiers designated by municipalities, this is the jurisdiction in which the growth tier is physically located. Municipal tiers that cross counties are divided at the county boundary so this field can be populated. See the MUNI field for the municipality responsible for designating a municipal tier.County – Full name of the jurisdiction represented by the JURSCODE.MUNI – The name of the municipality responsible for designating the tier. This field will be blank (‘ ‘) if the tier has been designated by a county. The MUNI field is formatted consistently with municipality names in the Planning’s municipal boundary datasets. When municipalities adopt tier maps by concurring with county tiers instead of submitting tier data independently, the MUNI field remains blank within the entire county tier map dataset. Depending on internal needs, an independent municipal tier dataset may or may not be generated by Planning and included within the aggregated tiers.TIER – Growth tier identifier used by the source jurisdiction and standardized as Tier 1, Tier 1A, Tier 2, Tier 2A, Tier 3, and Tier 4. May include additional alphabetical annotations used by the jurisdictions such as Tier 2B. If the TIER_CODE field is 99, the TIER field retains the descriptor provided by the jurisdiction, which may be a blank or null value.TIER_CODE – Integer field containing the growth tier standardized by Planning: 1 (Tier I); 11 (Tier IA or any other annotated version of Tier I, such as IB, etc.); 2 (Tier II), 22 (Tier IIA or any other annotated version of Tier II, such as IIB, etc.); 3 (Tier III); 4 (Tier IV); 44 (Areas annotated as Tier IVA for municipal greenbelts or any other annotated version of Tier IV); 99 – Areas included in the jurisdiction’s growth tier GIS data that are not assigned a tier, such as rights-of-way or water.Adopt_Date – Date growth tier map was adopted or amended. When a local jurisdiction updates its growth tier map, Planning generally requests a comprehensive GIS update to replace all existing data for the jurisdiction.Acres – GIS acres calculated by Planning in NAD83 Meters (EPSG 26985)GIS_SRC (GIS Source) – The original source of the GIS spatial and attribute information Planning obtained, which concatenates the JURSCODE field (or MUNI field for municipal tier maps), followed by a space, followed by the name of the shapefile or feature class received from the jurisdiction. Field contains “MDP” if tiers were digitized by Planning, and is blank (‘ ‘) for historical data.SRC_DATE (GIS Source Date) – The date (YYYYMMDD) the GIS data were obtained by Planning from the local jurisdiction. If the month or day is unknown, the date is YYYY0000. If Planning digitized the growth tier map in coordination with a local jurisdiction, this should be the date Planning’s edits are verified by the jurisdiction. This field will be blank (‘ ’) if Planning’s edits have not been verified or if the dataset is historical and the source is unknown.NOTE – Text field containing additional notes about the dataLast Updated: 7/26/2023This is a Maryland Department of Planning hosted service.

The map was developed using available parcel polygons attributed with tax assessment data as of project initiation in early 2020, Computer-Assisted Mass Appraisal (CAMA) data dated February 2020, and the Chesapeake Bay Program’s 2017/18 Land Use Land Cover data (2022 edition), subsequently referred to as “CBP LULC.” The map also incorporates land use datasets provided by county and municipal jurisdictions to the extent possible while maintaining standard statewide classification definitions and rules. The product was developed to be consistent with the 2018 National Agriculture Imagery Program (NAIP) imagery and CBP LULC dataset. MDP’s draft updated land use classification scheme is available as a separate document. This product is a beta release for public use and further testing. Methods for developing subsequent releases beyond this 2018 baseline will be refined based on feedback from the user community. Urban Land Uses 11 Low-density residential - Detached single-family/duplex dwelling units, yards, and associated areas. Includes generalized areas with lot sizes of less than five acres but at least one-half acre (0.2 to 2 dwelling units/acre). 12 Medium-density residential - Detached single-family/duplex, attached single-unit row housing, yards, and associated areas Includes generalized areas with lot sizes of less than one-half acre but at least one-eighth acre (2 to 8 dwelling units/acre). 13 High-density residential - Attached single-unit row housing, garden apartments, high-rise apartments/condominiums, mobile home and trailer parks, yards, and associated areas. Includes generalized areas with more than eight dwelling units per acre. This may include subsidized housing. 14 Commercial - Retail and wholesale services. Areas used primarily for the sale of products and services, including associated yards and parking areas. This category may include airports, welcome houses, telecommunication towers, and boat marinas. 15 Industrial - Manufacturing and industrial parks, including associated warehouses, storage yards, research laboratories, and parking areas. Warehouses that are returned by a commercial query should be categorized as industrial. This also includes power plants. 16 Institutional - Elementary and secondary schools, middle schools, junior and senior high schools, public and private colleges and universities, military installations (built-up areas only, including buildings and storage, training, and similar areas), churches, medical and health facilities, correctional facilities, government offices and facilities that are clearly separable from any surrounding natural or agricultural land cover, and other non-profit uses. 17 Extractive - Surface mining operations, including sand and gravel pits, quarries, coal surface mines, and deep coal mines. Status of activity (active vs. abandoned) is not distinguished. 18 Open urban land - Includes parks, open spaces, recreational areas not classified as institutional, golf courses, and cemeteries. Includes only built-up and turf-dominated areas that are clearly separable from any surrounding natural or agricultural land cover. 190 – Very Low Density Residential – Clustered residential parcels that have lot sizes less than 20 acres but at least five acres (0.2 to 0.05 dwelling units/acre) 50 – Water 80 Transportation - Transportation features include impervious roads, roadway rights-of-way, and parcels primarily containing light rail or metro stations and park-and-ride lots. 99 – Other Land - Remaining land not covered under another category. Examples include but are not limited to unbuilt lots, rural land, single-family residential parcels greater than or equal to 20 acres in size, and undeveloped portions of large parcels containing urban uses. May include undeveloped land that is either developable or constrained from further development. Note: Urban Land Use classifications encompass the entire parcel on parcels less than five acres that contain a structure as of 2018 based on the Maryland Department of Planning and Maryland State Department of Assessment and Taxation’s Computer-Assisted Mass Appraisal (CAMA) Building dataset. Elsewhere, the Chesapeake Bay Program’s 2017/18 Land Use Land Cover dataset (2022 edition) is used to delineate the extent of development on a parcel.

The Nature Conservancy (TNC) has been tracking and compiling information on conservation lands in the Northeast and Mid-Atlantic states for over 20 years. TNC’s Secured Areas (Conserved Lands) Dataset is compiled bi-annually from over sixty state, federal, and private source (See Lineage section of this metadata for full list of sources). The foundation of the dataset is public conservation land information maintained by each state, supplemented by federal land information from PAD-US and private conservation land information compiled by TNC’s state field offices.State-based TNC staff compile the data for their state, assign a TNC GAP status to each polygon, and populate other standard attribute fields. TNC assigned a GAP Status to all polygons to the best of our ability and in some cases altered GAP status found in original sources if further information was available. The completed state datasets were regionally compiled by TNC’s Center for Resilient Conservation Science (CRCS) and quality checked for consistency and discrepancies across the northeast.Definitions of GAP categories are given below and are described in terms of Conservation Management Categories as interpreted by TNC Center for Resilient Conservation Science.Conserved for Nature: GAP 1-2 Lands: Conservation land where the primary intent is the conservation of nature.GAP 1. Permanently Secured for Nature and Natural Processes : An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state where the area is allowed to “self-adjust” over time. Primary intention of the owner or easement holder is for biodiversity and nature protection. Land and water managed through natural processes including disturbances with little or no human intervention.GAP 2. Permanently Secured for Nature with Management : An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state, but which receives hands-on management. Primary intention of the owner or easement holder is for biodiversity and nature protection. Land and water managed with hands-on manipulation of processes, species composition, and disturbance.Conserved for Multiple Uses: GAP 3 Lands: Conservation land where the primary intent is multiple use. :GAP 3. Permanently Secured for Multiple Uses including extraction and recreation. : An area having permanent protection from conversion of natural land cover, but the primary intention of the owner or easement holder is for multiple uses, which may include biodiversity but also recreation and certain extractive uses. Extractive uses may include either a broad, low-intensity type (e.g., logging) or localized intense type (e.g., mining).Conserved for Agriculture: Conservation land where the primary intent is the preservation of farmland.GAP 39. Agricultural Easement: Land in a permanent agricultural easement or easement to maintain grass (e.g., vegetable farm with permanent easement to prevent development).Not Conserved Open SpaceGAP 4. Areas with no known mandate for permanent protection. Temporary easement lands (e.g., CREP 5-year term, similar X-year term agreements) and/or municipal lands (school yards, golf courses, soccer fields, ball fields, town commons) where intention in management and use of the open space is not biodiversity protection. It was beyond our capacity to comprehensively compile these GAP 4 lands, and as such, they are included only where source data made it feasible to easily incorporate them.Data Sources:

Various sources at the National, State, and sub-state level provide input to this dataset. Please see details below.

CONNECTICUT

Overview: This Connecticut Conservation Lands dataset was based on an update of the existing 2018 Secured Lands dataset compiled by TNC which had its roots in 1) the 2005 Protected Open Space Phase 1 dataset which mapped parcels designated as permanently protected open space by the Connecticut Department of Environmental Protection, 2) a Municipal and Private Open Space data layer from the Connecticut Office of Policy and Management DEP which mapped property owned by Connecticut municipalities and private organizations for the purpose of preserving open space including land conservation trust property, town open space, parks, school playgrounds, campgrounds, golf courses, club/association recreational property, and cemeteries, and 3) a DEP Property dataset which included state owned property such as natural area preserves, state forests, state parks, state park scenic reserves, state park trails, wildlife areas, and wildlife sanctuaries. This dataset was augmented in summer 2022 with updated TNC lands, Harvard Forest Wildlands 6/2022 parcels, Northeast Wilderness Trust properties, and a newly available protected open space dataset for eastern Connecticut from efforts of the CT Land Conservation Council/The Last Green Valley Protected Open Space Mapping Project (5/2/2022 Brian Hall, Hunter Brawley, Amy Patterson, Lois Bruinooge).

NEW JERSEY

Overview: The New Jersey Conservation Lands dataset was based primarily on the New Jersey Department of Environmental Protection (NJDEP), Green Acres Program state-local-and-nonprofit-open-space layer (version 20220810) which includes Green Acres encumbered and unencumbered protected open space and recreation areas. The Green Acres encumbered lands are owned in fee simple interest by either the state, county, municipality, or a nonprofit agency and have either received funding through the Green Acres State or Local Assistance Program or are listed on a Green Acres approved Recreation and Open Space Inventory (ROSI). The unencumbered open space lands do not fall under Green Acres rules and regulations and therefore have a lesser level of protection. Types of open space property in this data layer include parks, conservation areas, preserves, historic sites, recreational fields, beaches, etc. The data was derived from a variety of mapped sources which vary in scale and level of accuracy. This dataset was augmented with additional Federal conservation land from USGS Protected Areas Database 2.1, TNC lands as of September 2022, and the Farmland Preservation File.
