Public safety
Maricopa Fire Department was established in 1910 with Chief F. W. Ball serving as the first fire chief. Maricopa Hospital opened on April 22, 1911 and the city was incorporated on July 25, 1911. Gary Biggerstaff was the chief of police when budget problems forced the city to close its police department in 1998. The Kern County Sheriff's Department provided police services to the citizens of Maricopa from 1998 until 2006 when the city reopened its police department in the old building. As reported in the Los Angeles Times on July 4, 2011, the Maricopa Police Department has become embroiled in a local controversy playing out through large signs posted on the city's main thoroughfare. The police have been accused of racial profiling and "over-enforcement" regarding traffic violations and frequent towing of vehicles driven by drivers without proof of insurance or with license or license plate infractions. In mid-2011, American Civil Liberties Union lawyer Jennie Pasquarella is quoted as saying, "Maricopa has been a shining example of impoundments gone wrong," and "They're essentially creating a racket to steal people's cars." Police Chief Derek Merritt and other city officials have denied the charges.
