Historical district boundaries

The seat was originally one of five reapportioned to California after the 1970 U.S. census, but its boundaries have shifted radically through successive redistricting efforts. At various times it has included parts of Orange and San Diego counties, and from 1993 to 2003 it covered eastern San Bernardino and Inyo counties. From 2003 to 2013 the district was based in Orange County. The district covered the cities in the northern part of the county, including Fullerton, Orange, Cypress, Stanton, and Buena Park.
