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 or a series of bounding UTM coordinate pairs for properties over 10 acres. The polygons contained within this dataset represent boundaries created from connecting the bounding UTM coordinates submitted with the nomination. A building, such as a house, barn, church, hotel, or similar construction, iscreated 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.
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.

The Chattanooga/ Hamilton County/ North Georgia Transportation Planning Organization (CHCNGA TPO) is a federally‐designated Metropolitan Planning Organization. The TPO provides transportation planning services for Hamilton County and the northern portions of Dade, Walker, and Catoosa Counties. The TPO coordinates continuing, cooperative, and comprehensive transportation activities within the area along with the Tennessee and Georgia Departments of Transportation.
BOUNDARY HISTORY
The MPO was created in 1977 in compliance with the Federal Aid Highway Act of 1973 and the Urban Mass Transportation Act of 1964. The complete boundary history needs some research. In spring 2012, the Census Bureau released the new Urbanized Area boundaries for 2010. The Urbanized Area is a Census‐designated urban area with 50,000 residents or more. According to federal legislation, the TPO must carry out the metropolitan transportation planning process for the Urbanized Area and the contiguous geographic areas likely to become urbanized within the next 20 years.
According to FHWA, the Metropolitan Planning Area (MPA) must contain the Census Bureau defined UZA, not the adjusted UZA. However, Federal law requires that the entire UZA be included within the MPA as well as the contiguous area expected to be urbanized in the next 20 years (23 CFR 450.312.). Therefore, it is most likely that the MPA would need to include the entire adjusted UZA. Using the adjusted UZA as the base, the TPO staff considered several factors for consideration in delineating the regional transportation plan boundary. For the MPA update, staff reviewed the following (although not all information is available for the entirety of the planning area):
2000 and 2010 Urbanized Boundary
Previous and current/proposed Adjusted Urbanized Boundary
Functional Classification of Streets
Land use patterns
Input from GDOT or TDOT regarding boundary expansion
Transportation projects identified in the TIP
Subdivision and zoning patterns
Local partners can provide the best input on growth and development patterns in their areas including possible sewer expansion or other infrastructure projects. Therefore, staff discussed growth drivers with jurisdictional partners. TPO staff also provided material for review by the Northwest Georgia Regional Commission which oversees land use planning in North Georgia. TPO staff proposed a MPA boundary that included an expansion of the boundary Catoosa County, both an expansion and contraction in Dade County and no change in Hamilton and Walker Counties. The TPO Executive Board approved the Chattanooga‐Hamilton County/North Georgia Transportation Planning Organization Metropolitan Planning Area on June 18, 2013.
