Description: This dataset represents M-NCPPC park maintenance areas as defined by the Department of Parks & Recreation. There are three Maintenance Areas within Prince George's County: North, Central and South. Each area has its own designated maintenance and recreation supervisor.
Description: The dataset represents park buildings that are owned or serviced by the Department of Parks & Recreation in Prince George's County. Most park buildings are available for rent to the public and commonly include picnic areas adjacent to the buildings.
Description: The Environmental and Parks Easement layer is a graphic representation of areas for conservation in Prince George's County, based on Subtitle 24, Subdivision Regulations, Sections 129-135, of the County Code. These areas include, but not restricted to: cemeteries and related areas, conservation, floodplain, historic, landscape buffer, scenic, stormwater management easements.The features in this layer represent vegetated buffers preserved and/or restored along all regulated streams outside the Chesapeake Bay Critical Area Overlay Zones, which at a minimum includes the following features that are delineated as the Primary Management Area or PMA: (A) All regulated streams and associated minimum stream buffers; (B) The one hundred (100) year floodplain as defined by Section 27-124.01; (C) All wetlands and associated wetland buffers that are adjacent to the regulated stream, stream buffer or the one hundred (100) year floodplain; (D) All areas having slopes of fifteen (15%) or greater adjacent to the regulated stream or stream buffer, the one hundred (100) year floodplain, or adjacent wetlands or wetland buffers; (E) Adjacent critical habitat areas.This layer is a non-authoritative resource, indicating the presence of an easement based on information from the recorded final plat which would require additional research and consultation with Planning Department staff when analyzing and researching properties in Prince George's County.This layer is important when making long-range land use planning decisions, and also when on-site development activities occur. It is understood that this layer, for some time to come, will be incomplete, and, it may never be 100% complete simply because of the nature of easements and the fact that they can be established at different times in the process and through different means. The original easement data was recorded up to 2002, known in this layer as legacy data, when updates ceased until project continuation September 2010.

Description: This dataset contains two foot contours created from a bare earth digital elevation model (DEM) and only contains index and intermediate contours; there are no categories for hidden or depression contours. This data was captured for use in general mapping at a scale of 1:1200. Vertical Datum: NAVD88.
Description: This feature class describes Prince George's County's Environmental Strategy Areas (ESAs), which guide stream and wetland buffer requirements. Areas 1, 2, and 3 coincide with the 2002 General Plan Tiers, where ESA 1 is the Developed Tier, ESA 2 is the Developing Tier, and ESA 3 is the Rural Tier. ESA 4 is the Chesapeake Bay Critical Area Overlay Zone (CBCA). ESA 4 is further subdivided into three CBCA zones -- Resource Conservation, Limited Development, and Intense Development -- which also have implications for stream buffer requirements.
Description: The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Datum of 1983.Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded).
Description: This dataset contains impervious surfaces within Prince George's County. Impervious surfaces are attributed by type. All remaining surfaces that do not fall under one of the 'Type' categories are classified as pervious. Impervious Surface features derived as a byproduct of the photogrammetric capture of planimetric features, for use in general mapping at a scale of 1:1200, using stereo imagery taken to satisfy creation of 6 inch ground pixel resolution orthophotography. The original data was developed using photography taken from March of 2009. It was then updated in 2014 using photography taken during March/April of 2014.
Description: Natural Resource Inventories depict the existing features found on a tract of land prior to subdivision. They include all existing site features, historic features, and the regulated natural resources necessary to evaluate a site prior to development. Natural Resource Inventories are reviewed by the M-NCPPC EPS staff for signature approval. A signed NRI must accompany a preliminary plan application.

Description: This dataset show steep and sever slopes developed from a DEM dataset for Prince George's County. This includes slopes with a percent rise between 15% and 25%, and greater than 25%. This data was captured for use in general mapping at a scale of 1:1200.
Description: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.This data set has been customized for use by the M-NCPPC, Prince George's County Planning Department as follows: the Soil Data Viewer ArcMap extension was used to symbolize soil mapunit data for each of the following categories: Drainage Class, Hydric Rating, Hydologic Soil Group, K-factor (whole soil), and Mapunit name. Each data sets symbology, produced by the Soil Data Viewer, was saved as a layer and each data table was joined to the data set for Mapunit name, using MUKEY as the join field. The layer files were repointed to this combined data set and more descriptive items were included in the layer file where appropriate.
Description: This dataset contains dams, headwalls, floodwalls, bulkheads, canals, water cooling channels, drainage connectors, and single line streams within Prince George's County. Canals, water cooling channels, and streams that run below elevated structures or underground are shown with a hidden feature code. Single line streams are those that are less than 20 feet in width. Centerlines of streams greater than 20 feet in width are shown with a separate feature code. Dams in this layer include those smaller ones found in creeks. This data was captured for use in general mapping at a scale of 1:1200.
Description: This dataset contains woodlands greater than 5000 square feet or one tenth of an acre within Prince George's County. The dripline of wooded areas was captured so it may run through other features. This data was captured for use in general mapping at a scale of 1:1200.

Description: This file is a statewide digital watershed file. It was created primarily for state and federal agency use. The watersheds define Strahler (Strahler 1952 p. 1120) third order stream drainage by contours on U.S. Geological Survey (USGS) 7.5 minute quadrangle map sheets. Some watersheds drainage areas were defined for streams less than third order and some large area watershed were split to maintain a maximum size of 15,000 acres. The watershed boundaries in this file were developed in a joint state and federal effort to create a consistent watershed file for use by all government agencies with an interest in Maryland's watersheds. The U.S. Natural Resources Conservation Service (NRCS) redefined the third order watersheds creating the HUA14 file. This file contains all of the HUA14 watersheds and some added watersheds to maintain water quality sampling sites. It was also used to create the Maryland Sub-Watershed file.
Copyright Text: The original eight digit watershed file was created in 1991 from Maryland Department of the Environment (MDE) hardcopy watershed maps. The Maryland Office of Planning (OP) created that digital file by contracting with Daft, McCune and Walker to digitize third order stream watersheds. The U.S. Natural Resources Conservation Service (NRCS) produced the Hydrological Unit Code watershed file HUA14 using the OP file as a base map and redefining watersheds. NCRS field offices verified the watershed boundaries. The Maryland Department of Housing and Community Development Maryland Historic Trust (MHT) provided scanned US Geological Survey (USGS) 7.5 minute quadrangle map sheets to be used as a base map for corrections. The Department of Natural Resources (DNR) corrected the watershed boundaries to the scanned USGS 7.5 minute quadrangle map sheets in cooperation with NRCS. The State political boundary file from Maryland State Highway Administration's (SHA) GRID map series was merged into the file replacing the existing state line. The merge and watershed corrections were completed by DNR.

Description: In Maryland certain wetlands with rare, threatened, endangered species or unique habitat receive special attention. The Code of Maryland Regulations (COMAR) Title 26, Subtitle 23, Chapter 06, Sections 01 & 02 identifies these Wetlands of Special State Concern (WSSC) and affords them certain protections including a 100 foot buffer from development. The Maryland Department of the Environment is responsible for identifying and regulating these wetlands. In general, the US Fish and Wildlife Service's National Wetlands Inventory wetlands provide the basis for identifying these special wetlands. Additional information, determined from field inspections, is used to identify and classify these areas.

Description: Woodland Conservation Areas (WCA) are captured to support the annual reporting of the State Forest Conservation Act 0f 1991 by further delineating certain conservation easements into distinct planted, retained, and floodplain areas. The source information for each WCA shape is found on approved Type Two Tree Conservation Plans (TCP II), approved by the Prince George’s County Planning Department, for each fiscal year, beginning in 2009.
Description: The public land datais mapped to support reporting efforts, as they relate to Sec. 2-111.01. - Sale, lease, or other disposition of County property.of the County Code of Prince George's County, under Subtitle 2 - Administration, Division 2 - County Executive. The datawas extracted by exempt class code from SDAT records designated as public lands. This includes Federal Real Property (Codes 100-190), State owner real property (200-390), County owned (400-590) and Town or Municipality Owned (600-690). This data was compared to an existing report of public lands from Prince George's county, discrepancies between the two data sources were reviewed and resolved in the most appropriate way possible. Account information is related to individual properties and multiple properties are combined to create a singular site, which would be assigned a unique site ID. Accounts that were located were mapped and joined to the Department's Property_Flattened_Py feature class; accounts that could not be located are flagged in the source Oracle table and not mapped. The feature data and table are used to validate existing public land properties for an annual report generated for Prince George's County Department of the Environment. Data will be maintained on an annual basis by deriving extracts from the SDAT database and soliciting input from owning agencies.
Description: This dataset contains roads, parking lots, runways and taxiways, driveways, railroad beds, and walkways/sidewalks within Prince George's County. Roads, parking lots, and railroad beds are attributed with surface type. Driveways, runways and taxiways, and walkways/sidewalks are attributed as either paved or unpaved. This data was captured for use in general mapping at a scale of 1:1200.
