The CA 2020 adjusted urban area file represents the current Federal Highway Administration (FHWA) approved Caltrans adjusted urban area boundaries. These CA 2020 adjusted urban area boundaries were derived from the 2020 Census urban area boundaries, the preceding 2010 Caltrans urban area boundaries, and approved district and headquarters urban area adjustments. The three urban area boundaries were merged and smoothed to create the 2020 adjusted urban area boundaries for California. The adjusted urban boundaries have been approved by the FHWA. |
