The U.S. Geological Survey (USGS) entered into cooperative agreements with the Santa Barbara County Water Agency and Vandenberg Space Force Base to conduct a hydrologic resource assessment and develop an integrated numerical hydrologic model of the San Antonio Creek Valley watershed (SACVW). As part of this study, the USGS developed a digital three-dimensional hydrogeologic framework model (HFM). This dataset contains a geospatial database related to the digital HFM, individual geographic information system (GIS) shapefiles from the geodatabase, and borehole data used to support development of the HFM in a Microsoft Excel workbook (*.xlsx extension). The geospatial database contains the following data elements: (1) a boundary polygon that defines the HFM extent; (2) line features that define the location of faults used in the HFM; (3) a point dataset defining location of boreholes used in HFM construction; and (4) a polygon feature class containing interpolated elevations and thicknesses of hydrogeologic units as a cellular array. The spatial data are accompanied by non-spatial tables that describe the sources of geologic information, a glossary of terms, a description of model units, and a Data Dictionary. Spatial data are also presented as shapefiles and borehole data are provided in Mircosoft Excel spreadsheet.
