Adjusted Urban Areas

2010 Adjusted Urban Areas

The 2010 adjusted urban area file represents the current Federal Highway Administration (FHWA) approved Caltrans adjusted urban area boundaries in California.

Data Created: October 1, 2013
Last Modified: October 26, 2016


These 2010 adjusted urban area boundaries were derived from the 2010 Census urban area boundaries, the preceding 2000 Caltrans urban area boundaries, and approved district and headquarters urban area adjustments. The three urban area boundaries were merged and smoothed to create the 170 adjusted urban area boundaries for California. The adjusted urban boundaries have been approved by the FHWA.


This data is made available to the public solely for informational purposes. Every reasonable effort has been made to ensure the accuracy of the data. There are no restrictions on distribution of the data by users. However, users are encouraged to refer others to the Department of Transportation GIS Data Library to acquire the data, in case updated data become available.
