SACOG creates and maintains a tremendous quantity of data about the Sacramento region which covers El Dorado, Placer, Sacramento, Sutter, Yolo and Yuba Counties and the cities within each county. Please note that SACOG does not cover the Tahoe Basin portions of El Dorado or Placer County nor the City of South Lake Tahoe. Those geographies are covered by the Tahoe Regional Planning Agency (TRPA) however many data sources do not break out the Tahoe Basin separately.
This website contains only a small portion of the data that are available. If we don’t have the data you’re looking for, we may be able to refer you to another source(s) of information. Please email firstname.lastname@example.org or call SACOG’s front desk (916) 321-9000 for more information.

The U.S. Census Bureau is Constitutionally mandated to count every resident in the United States every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions of dollars in federal funds to local communities each year.
Please contact Tina Glover for more information.
The Regional GIS Clearinghouse contains metadata, file owner-maintainer information, and in some cases ESRI based shapefiles for the basic mapping layers in our region. In most cases, these GIS infrastructure layers have been developed on the County parcel base map. Users should read each metadata file to determine the appropriate uses and related layers that they can be used for.
