The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Sacramento Basin Province is located in the Northern Central Valley, California, encompassing all or parts of Shasta, Tehana, Glenn, Butte, Colusa, Lake, Yuba, Sutter, Placer, Yolo, Napa, Sacramento, Amador, San Joaquin, Solano, Contra Costa, Calaveras, Alameda, and Stanislaus counties in California. The main population centers within the study area are Sacramento, Stockton, Modesto, Elk Grove, Yuba City, Chico, and Red Bluff, California. The main highways, I-5 and I-80, generally traverse the area from north to south and east to west respectively. The Sacramento River and its tributaries drai ...

SACOG Region : El Dorado, Placer, Sacramento, Sutter, Yolo, and Yuba Counties in California.The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. A block may consist of one or more faces. Block Groups are the first level of Block aggregation.

The annexation data set contains all of the annexations, detachments, land grants, additions, consolidations, subtractions, reorganizations, and relocations of the city boundary since 1849. It is updated from council approved ordinances and resolutions and coordination with LAFCo. Updates to boundary data set are updated on a regular basis to reflect adjustments to base and re-interpretations of legal descriptions.

Census 2010 Tract Data with DemographicsCensus Tracts are the second level of Census Block aggregation. They can also be aggregated from Block Groups. Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. They are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. All 2010 Census blocks nest within every other 2010 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas.

This shapefile contains tax rate area (TRA) boundaries in Sacramento County for the specified assessment roll year. Boundary alignment is based on the 2021 county parcel map. A tax rate area (TRA) is a geographic area within the jurisdiction of a unique combination of cities, schools, and revenue districts that utilize the regular city or county assessment roll, per Government Code 54900. Each TRA is assigned a six-digit numeric identifier, referred to as a TRA number. TRA = tax rate area number
