Camarillo became a city in 1964 and soon put into place a General Plan and building codes. In 1964 the closest traffic signal was 2 miles from the city center on the road to Point Mugu, and the first shopping center and supermarket were under construction.
Because of the late date of city incorporation, the local telephone exchange is still listed as part of Oxnard. Much of the city was expected to be developed to the south of Ventura Boulevard, however the city grew to the north, and most of the land south of Ventura Boulevard remains in agricultural use. In the mid-1990s, multiple large retail centers, including one of California's largest outlet malls and movie theater were built south of US 101 and west of Carmen Drive.
