California Valley area, much of it by local residents, posing serious environmental issues. In 2006, a combined effort by the California Highway Patrol, California Department of Motor Vehicles, San Luis Obispo County Code Enforcement, and local businesses worked together to remove abandoned vehicles and accumulated trash. Infrastructure California Valley is located on Soda Lake Road about two miles (3 km) south of State Route 58. A small general store is closed, as well as the previously popular small restaurant. The community is served by a school and community center with library, open only on Wednesdays. Other than State Route 58 and Bitterwater Road, access is mainly through the Carrizo Plain via Soda Lake Road, which is a seasonal improved dirt road south of Soda Lake to State Route 33/State Route 166; or via smaller seasonal dirt roads to the east and south. No scheduled bus routes serve the community, and there are no rail lines. Private airport The private and restricted California Valley Airport Class II-C paved runway extends south from the community center but is not marked on current aeronautical charts and is painted at the south end with a white "X" indicating that it is closed although it can be used with advance permission. Services Community services are provided by the California Valley Community Service District (CSD). This includes road maintenance and limited trash service. The Community Center includes a fire station, small library, and community assembly hall. The address is 13084 Soda Lake Road, on the south side of Soda Lake Road, approximately south of Highway 58, in the village of California Valley. Water, a porta-potty and a pay phone are available at the Community Center. The quality of the water is in dispute. Many California Valley residents consider the water potable, but signage to the contrary has been posted in the past. Electricity is available in parts of California Valley. Telephone service is available through SBC. The local prefix is (805) 475-XXXX. There is strong analog mobile phone coverage and limited ("backscatter") GSM mobile phone coverage, as well as limited Nextel coverage. Verizon Wireless does have a sole tower which overlooks and covers a good portion of the valley. The local zip code is 93453. Mail is delivered to drop boxes at the Community Center. Main roads (Belmont Trail, Soda Lake Road, Seven Mile Road) are paved to an extent. Others are packed dirt or decomposed
