Map document to support the map and/or feature services for public, non-restricted National Register of Historic Places spatial data.A current, accurate spatial representation of all historic properties listed on the National Register of Historic Places is of interest to Federal agencies, the National Park Service, State Historic and Tribal Historic Preservation Offices, local government and certified local governments, consultants, academia, and the interested public. This interest stems from the regulatory processes of managing cultural resources that are consistent with the National Historic Preservation Act as Amended (NHPA), the National Environmental Policy Act as Amended, the Archaeological Resources Protection Act, and other laws related to cultural resources. The regulations promulgating these laws require the use of spatial data in support of various decisions and actions related to cultural resource management. Collectively, the National Register geo-spatial dataset is intended to be a comprehensive inventory of all cultural resources that are listed on the National Register of Historic Places.

This dataset includes buildings and districts in Chicago which are listed on the National Register of Historic Places (NRHP) or designated as National Historic Landmarks (NHL). The NRHP is the official list of the Nation's historic places worthy of preservation; NHLs are nationally significant historic places designated by the Secretary of the Interior because they possess exceptional value or quality in illustrating or interpreting the heritage of the United States. The NRHP and NHL programs are federally-established and are administered by the National Park Service (www.nps/gov/nr) and the Illinois Historic Preservation Agency (IHPA, www.illinoishistory.gov/). This dataset is provided by the City of Chicago based on NRHP and NHL nominations provided by IHPA.

The National Register geospatial dataset is intended to be a comprehensive inventory of all cultural resources that are listed on the National Register of Historic Places. However, this dataset excludes all features deemed 'restricted' or 'sensitive', such as sensitive archaeological sites. This dataset provides feature geometry representations (point or polygon) and is intended to be supplemented with descriptive attributes maintained by other external database systems such as the National Register Information System which is included in this geodatabase.

Description This polygon layer contains buildings, sites, structures, objects, and districts that have been placed on the National Register of Historic Places in recognition of their importance to American history, culture, or archaeology. National Register designation means that changes to these places must be reviewed if federal or state funds, permits, or licenses are used.

This feature defines the geographic area of National Register Historic Districts within the City of Austin.

In August 2005, Brockington and Associates, Inc., conducted a cultural resources survey of the 51.2 hectare Stono View tract, located on Johns Island, Charleston County, South Carolina. This survey included a background review and the systematic excavation of shovel tests at 15 and 30 meter intervals across the upland portions of the project tract. All dirt roads on the tract were visually inspected. No extant buildings or structures are located on the project tract. Three houses (297 1384, 297 1385, and 297 1386) greater than 50 years of age are located adjacent to the Stono View tract, all three were recommended not eligible the NRHP (Fick et al. 1989). Investigators identified two archaeological sites (38CH2069 and 38CH2070) during the cultural resources survey of the Stono View tract. Archaeological site 38CH2069 is a diffuse subsurface scatter of Pre-Contact ceramics attributed to an unknown Pre-Contact occupation. Site 38CH2070 contains a light subsurface scatter of nineteenth century Post-Contact artifacts. We recommend sites 38CH2069 and 38CH2070 not eligible for the NRHP. No further management of these sites is warranted.

These points are directly sourced from the National Historic Landmarks, National Register, State Register, Local Historic Districts, Local Historic Places, Historic Resources inventories, CHC files, Connecticut Barns listings, Connecticut Arts & letters listings, Connecticut Making Places listings, Connecticut Freedom Trail listings, and various special surveys (Sculpture, Civil War Monuments, Municipal Parks, Town Greens, Historic Bridges). If a resource appears in multiple pdfs, it will appear as one entry.The geolocation of these points is based on the addresses and pre-existing maps that appear in the associated pdfs of the resources. Some resources were unable to be geolocated; but will still appear in the attribute table of this layer.The following is a list of the sources for each resource with their associated designation:1). National Historic Landmark (NHL); with the designation “NHL”.2). National Register (NR); with the designation “NRIND” for individual resources or NRDIS for NR Districts. A “-C” or a “-NC” is added at the end of NRIND or NRDIS to indicate if it is a contributing or non-contributing resource.3). Restricted National Register (RNR); with the designation “NRIND” for individual resources or NRDIS for NR Districts. A “-C” or a “-NC” is added at the end of NRIND or NRDIS to indicate if it is a contributing or non-contributing resource. These resources are not geolocated and their pdfs are no available to be viewed on the public viewer.4). State Register (SR); with the designation “SRIND” for individual resources or SRDIS for SR Districts. A “-C” or a “-NC” is added at the end of SRIND or SRDIS to indicate if it is a contributing or non-contributing resource. Every resource listed in the NHL or NR have a "SRIND" or "SRDIS" designation as they are automatically placed on the state register if they are added to the NHL or NR. In instances where that is the case, there will be no accompanying SR associated with it. Similarly, everything with a CHC listing, also has a SRIND designation. Some SR resources are referred to as 'LHD' within the documentation, this is because every proposed LHD pre-2019 that failed to pass LHD were automatically added to the state register.5). Local Historic Place (LHP); with the designation “LHP”.6). Local Historic District (LHD); with the designation “LHD”.7). Historic Resource Surveys (HRI)8). Survey of Outdoor Sculptures (SOS)9). Civil War Monuments (CWM)10). Municipal Parks (MP)11). Historic Bridges (HB)12). Town Greens (TG)13). Connecticut Freedom Trails (CFTs)14). Connecticut Barns (Barns)15). Creative Places16). Making Places17). Connecticut Historic Commission (CHC)18). State Owned Buildings: resources with this source were listed in the 1988 State Owned Buildings surveys and may not be reflective of present-day state-owned resources.

Reason for Selection Low-urban historic landscapes indicate significant cultural landscapes whose cultural context has been less impacted by urban development. Cultural landscapes are “properties [that] represent the combined works of nature and of man” (UNESCO 2012). Loss of natural habitat within these cultural landscapes reduces their overall historic and cultural value. Input Data South Atlantic Blueprint 2021 extentSoutheast Blueprint 2023 extent2016 National Land Cover Database (NLCD): Land coverThe following National Register of Historic Places data from the National Park Service and various State Historic Preservation Officers: The National Register of Historic Places, accessed March 2021: All point layers from the NRIS_CR_Standards_Public geodatabase, including historic buildings, districts, objects, sites and structures. We use this data only in Alabama and Georgia, where no improved state-specific layer is available. Some states maintain their own, improved versions of the National Register of Historic Places, while other states rely on the nationwide version maintained by the National Park Service. In Virginia, North Carolina, Florida, and South Carolina, we obtained the following state-specific point and polygon data for places on the National Register:Virginia listed historic districts boundariesVirginia listed site pointsNorth Carolina local district boundariesNorth Carolina NCHPO_NR_SL_DOE_BoundariesNorth Carolina NCHPO pointsFlorida national registerSouth Carolina NRHP_Districts-Areas_Non-RestrictedSC_NRHP_Structures_points Non-Restricted The National Register of Historic Places reflects what Americans value in their historic built environment. It is the collection of our human imprint on the landscape that records through time our changing relationship with the landscape, bridging between modern life and our history by providing, as closely as possible, experiences that evoke our empathy and understanding of previous eras. Mapping Steps Define urban areas using the following classes from the 2019 NLCD - Developed, High Intensity; Developed, Medium Intensity; Developed, Low Intensity; Developed, Open Space. Classify all urban pixels as 1 and all other pixels as 0.Calculate the percent urban in a 270 m radius circle for each pixel using the Focal Statistics tool in ArcGIS. Since the NLCD data resolution is 30 m pixels, use 270 m (9 pixels) to approximate a 250 m radius. Retain all pixels that are <50% urban within a 270 m radius. Create a historic places layer as follows:The North Carolina NCHPO points file contains points for both state-level and national-level historic places. To make these data comparable with data from other states, remove the state-specific points using information from the attribute table (remove any point that has a blank value for the YearNR field).Merge together the state-specific point layers (NC, SC, and VA) and the National Park Service-maintained National Register of Historic Places point layers (AL and GA) and buffer by 100 m.Merge all polygon data and buffered point data into one layer and convert to a 30 m raster.Use the historic places raster to remove areas that fall outside of the historic places.Reclassify the above raster into 3 classes, seen in the final indicator values below.Clip to the spatial extent of the South Atlantic Blueprint.As a final step, clip to the spatial extent of Southeast Blueprint 2023. Note: For more details on the mapping steps, code used to create this layer is available in the Southeast Blueprint Data Download under > 6_Code.Final indicator valuesIndicator values are assigned as follows:2 = Historic place with nearby low-urban buffer1 = Historic place with nearby high-urban buffer0 = Not in the National Register of Historic Places Known IssuesThere are spatial mapping errors for some of the historic areas. Some historic areas with cultural importance are not necessarily captured in the National Register of Historic Places. The approach to measuring urban growth doesn’t capture degradation to historic places that were historically in larger cities (e.g., courthouses and other downtown buildings). It also doesn’t distinguish between historic places that have always been urban and historic places that used to be low-urban. This layer underrepresents some historic areas in Georgia and Alabama because we only used the point data from the National Register of Historic Places maintained by the National Park Service. We omit the polygon layers because they contain many GIS errors and often overestimate the extent of historic sites. Disclaimer: Comparing with Older Indicator VersionsThere are numerous problems with using Southeast Blueprint indicators for change analysis. Please consult Blueprint staff if you would like to do this (email hilary_morris@fws.gov).
