Camarillo is named for Adolfo and Juan Camarillo, two of the few Californios (pre-1848 California natives of Hispanic ancestry) to preserve the city's heritage after the arrival of Anglo settlers. As with most cities in Ventura County, it is noted for its resistance to new development. Some of the most desirable land in the city limits, located on the north and south sides of the Ventura Freeway, is permanently zoned for agricultural use. The construction in these zones shows the progress made towards erosion of this permanence.
Camarillo and the surrounding area has a temperate, Mediterranean-type climate. Its location in a coastal valley brings mild ocean breezes and temperatures in the 70s throughout most of the year. An average rainfall of 13 inches (330 mm) occurs primarily from November to February. The city has over 300 days of sunshine a year and an average humidity of 62%.
Snow has only fallen about 3 times in the last thirty years and is seldom more than a dusting. Snow is often visible during the winter months above the 4,000-foot (1,200 m) level in the mountains to the north. The proximity of the ocean sometimes causes morning fog in the spring and early summer.
The Pleasant Valley Recreation & Park District (PVRPD, www.pvrpd.org) is an independent Special-purpose district located in Ventura County, California. The District is located in and around the City of Camarillo, serves a population of over 70,000 and covers an area approximately 45 square miles [verification needed]. It has grown from one park and 30 acres to 27 parks and over 300 acres since its inception in 1962. PVRPD was incorporated prior to the City of Camarillo.
