These ESRI shape files contain National Park Service tract and boundary data created by the Land Resources Division. The tract data is essentially all of the parcel boundaries associated within and adjoining the San Antonio Missions National Historical Park as legislated by congress. The boundary data is the current legislated park boundary. Tracts are created from deeds, plats and surveys of record then assigned a number by regional cartographic staff at the Land Resources Program Centers. This spatial data is used as the basis for NPS Land Status Maps.

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over an 8-day period in Louisiana in August and September 2017. Following the storm event, U.S. Geological Survey (USGS) hydrographers recovered and documented 2,123 high-water marks in Texas, noting location and height of the water above land surface. Many of these high-water marks were used to create flood-inundation maps for selected communities of Texas that experienced flooding in August and September, 2017. The mapped area boundary, flood inundation extents, depth rasters, and coastal surge layer were created to provide an estimated extent of flood inundation in Coastal basins including East and West Matagorda Bay Subbasins, East and West San Antonio Bay Subbasins, and Aransas Bay Subbasin, Texas. The mapped area of the Coastal basins were separated into three sections based on the availability and location of high-water marks. The maps of the eastern part of the East Matagorda Bay Subbasin include a 17-mi reach of Peyton Creek and a 16-mi reach of Big Boggy Creek, and flood-inundation map for 6-mi reach of Little Boggy Creek in Matagorda County. The maps of the western part of East Matagorda Bay Subbasin include a 13.5-mi reach of West Carancahua Creek, 14.5-mi reach of East Carancahua Creek, and 9.6-mi reach of Keller Creek within Matagorda, Jackson, and Calhoun Counties. The maps of the middle part of the East Matagorda Bay Subbasin are for a 21-mi reach of the Tres Palacios River within Matagorda County. These geospatial data include the following items: 1. bnd_emb1, bnd_emb2, and bnd_tres_palacios; shapefiles containing the polygon showing the mapped area boundary for the Coastal basins flood maps, 2. hwm_emb_1, hwm_emb2, and hwm_tres_palacios; shapefiles containing high-water mark points used for inundation maps, 3. polygon_emb1, polygon_emb_2, and polygon_tres_palacios; shapefiles containing mapped extent of flood inundation for the Coastal basins, derived from the water-surface elevation surveyed at high-water marks, 4. depth_emb1, depth_emb2, and depth_tres; raster files for the flood depths derived from the water-surface elevation surveyed at high-water marks, and 5. coastal_surge.lyr; a layer file generated from the depth raster depicting water height above ground recorded at the high-water marks. The upstream and downstream mapped area extent is limited to the upstream-most and downstream-most high-water mark locations. In areas of uncertainty of flood extent, the mapped area boundary is lined up with the flood inundation polygon extent. The mapped area boundary polygon was used to extract the final flood inundation polygon and depth raster from the water-surface elevation raster file. Depth raster files were created using the "Topo to Raster" tool in ArcMap (ESRI, 2012). The HWM elevation data from the USGS Short-tern Network (STN) was used to create the flood water-surface raster file (U.S. Geological Survey [USGS], 2018, Short-Term Network Data Portal: USGS flood information web page, accessed February 13, 2018, at https://water.usgs.gov/floods/FEV.). The water-surface raster was the basis for the creation of the final flood inundation polygon and depth layer to support the development of flood inundation map for the Federal Emergency Management Agency's (FEMA) response and recovery operations.

The SAPD Bike Patrol Areas are not used as beats, districts, etc, but rather as areas to help break apart their service area. It is not clear to what extent that the San Antonio Police Department uses these areas outside illustrating Bike Patrol's service area.

NOAA provided Atlas 14, Volume 11 rainfall data in a GIS compatible ASCii format. The resulting processed rainfall isopluvials align in a general east-west direction. Using the east-west isopluvial orientation as a general guide, the datasets listed below were used to inform and refine the delineation of the Precipitation Area boundaries. The five (5) Precipitation Areas are generally orientated lengthwise in an east-west direction to follow the isopluvial orientation. Precipitation Area numbering followed a north-south direction, with PA-1 being the most northerly area and PA-5 being the most southerly area.Datasets used to inform the PA boundary delineations and source (acquired in 2018):• San Antonio River watershed subbasins - San Antonio River Authority• HUC 12 layers – Texas Natural Resources Information System• Rivers & Creeks – United States Geological Survey• Bexar County boundary – City of San Antonio• Cibolo Creek subbasins – San Antonio River AuthorityThis dataset will be evaluated for general accuracy on an annual basis, or more frequently as necessary.

Census Tract boundaries within Bexar County. A census tract is a geographic region defined for the purpose of taking a census. Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas of the United States these are often arbitrary, except for coinciding with political lines. In the United States, census tracts are subdivided into block groups and census blocks. According to the U.S. Census Bureau: Census tracts are designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions, census tracts average about 4,000 inhabitants.
