Name: Historic Building - National Register of Historic Places
Display Field: RESNAME
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This feature class describes properties listed on the National Register of Historic Places, classified as historic buildings, and depicted as points. The National Register of Historic Places requires the submission of a single UTM coordinate pair for properties under 10 acres. A building, such as a house, barn, church, hotel, or similar construction, is created principally to shelter any form of human activity. A building may also be used to refer to a historically and functionally related unit, such as a courthouse and jail or a house and barn. Buildings include: houses, barns, stables, sheds, garages, courthouses, city halls, social halls, commercial buildings, libraries, factories, mills, train depots, stationary mobile homees, hotels, theaters, schools, stores and churches. Attribute data in this dataset are intentionally limited to those necessary for spatial data maintenance and feature level metadata necessary to document the lineage of the geography itself. Data from external database systems, such as the National Register Information System, are intended to link with these data to provide basic feature attributes. The means to maintain unique identifiers for each historic site (CR_ID), Survey_ID, as well as unique geometries associated with that feature (Geometry_ID) are through the use of Globally Unique Identifiers (GUIDs) assigned by the database. Information about the genesis of individual points is documented by feature level metadata fields in the spatial attribute table.

Name: Historic Site - National Register of Historic Places
Display Field: RESNAME
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This feature class describes properties listed on the National Register of Historic Places, classified as historic sites, and depicted as points. The National Register of Historic Places requires the submission of a single UTM coordinate pair for properties under 10 acres. A site is the location of a significant event, a prehistoric or historic occupation or activities, or a building or structure, whether standing, ruined or vanished, where the location itself possess historic, cultural or archaeological value regardless of the value of any existing structure. Sites include: habitation sites, rock shelters, village sites, ceremonial sites, petroglyphs, gardens, grounds, battlefields, ruins of historic buildings and structures, campsites, areas of land, shipwrecks, cemeteries, designed landscapes, archaeological sites and landscapes having cultural significance. Attribute data in this dataset are intentionally limited to those necessary for spatial data maintenance and feature level metadata necessary to document the lineage of the geography itself. Data from external database systems, such as the National Register Information System, are intended to link with these data to provide basic feature attributes.

Name: Historic Structure - National Register of Historic Places
Display Field: RESNAME
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This feature class describes properties listed on the National Register of Historic Places, classified as historic structures, and depicted as points. The National Register of Historic Places requires the submission of a single UTM coordinate pair for properties under 10 acres. A structure is a building whose functional construction is made usually for purposes other than creating human shelter. Structures include: bridges, tunnels, gold dredges, firetowers, canals, turbines, dams, power plants, corncribs, silos, roadways, shot towers, windmills, grain elevators, kilns, mounds, cairns, palisade fortifications, earthworks, railroad grades, systems of roadways and paths, boats and ships, railroad locomotives and cars, telescopes, carousels, bandstands, gazebos and aircraft.

Description: EJSCREEN is an environmental justice (EJ) screening and mapping tool that provides EPA with a nationally consistent dataset and methodology for calculating "EJ indexes," which can be used for highlighting places that may be candidates for further review, analysis, or outreach as the agency develops programs, policies and other activities. The tool provides both summary and detailed information at the Census block group level or a user-defined area for both demographic and environmental indicators. The summary information is in the form of EJ Indexes which combine demographic information with a single environmental indicator (such as proximity to traffic) that can help identify communities living in areas with greater potential for environmental and health impacts. The tool also provides additional detailed demographic and environmental information to supplement screening analyses. EJSCREEN displays this information in color-coded maps, bar charts, and standard reports. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block groups. Data on the full range of environmental impacts and demographic factors in any given location are almost certainly not available directly through this tool, and its initial results should be supplemented with additional information and local knowledge before making any judgments about potential areas of EJ concern.
Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
Name: Land Use 2016 - Hamilton Regional Planning Agency
Display Field: SITE_NAME
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The Land Use feature class presents a uniform picture of parcel based land uses across the entire TPO. County-specific land uses are reclassified by Chattanooga-Hamilton County Regional Planning Agency (RPA) staff to a single, standard set of land uses suitable for the entire TPO area (with one exception, 640 - Georgia Conservation Covenant). It is a two-tiered approach that generates both a general land use category and a detailed land use code. The parcel data were nominally acquired between 2015 and 2016. HistoryThe Land Use Feature Class was first created in the summer of 1999. A land use field survey was conducted for Hamilton County and observations were stored in a parcel shapefile. There have been several major updates to the file in 2007, 2010, and 2016. Small areas or neighborhoods are updated as resources are available. In 2016 the GA portion of the TPO was added to the file.
