List of contract law enforcement municipalities in the United States

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This list is intended to be a listing of law enforcement agencies (or cities) that contract with other government agencies to provide law enforcement (police) services. In California, Washington, and Florida, this is typically done when a city contracts with the county sheriff to provide city police services.

In other states, such as Pennsylvania, it could be through one or more municipalities contracting with an existing municipal police agency. Sometimes two or more departments merge to form a "Regional Police Department." These are not examples of contract cities. Similarly, mergers of municipal police and county sheriff's departments (such as those of Indianapolis, Las Vegas, Louisville, and Nashville) do not result in contract cities, as the cities do not contract for services.

The idea of contract law enforcement was pioneered by the Los Angeles Sheriff's Department in 1954. It is known as the "Lakewood Plan"[1] and came about during the post World War II growth of the baby boom of the 1950s in Southern California. The newly-incorporated City of Lakewood contracted with the sheriff's department to provide its police services. Prior to the incorporation of Lakewood, the LASD was already patrolling that unincorporated area.
