Interlocal Cooperation in Law Enforcement
This page provides a basic overview of interlocal cooperation in law enforcement in Washington State, including examples of interlocal agreements between cities, counties, American Indian tribes, or other government agencies.
It is part of MRSC's series on Interlocal Cooperation.
Overview
A city or town may provide law enforcement protection in a number of different ways. The traditional and most common way is to establish a municipal police department under the direction of a locally appointed police chief or marshal.
Counties provide law enforcement through the sheriff's office.
Many local governments enter into contractual arrangements with other jurisdictions to provide law enforcement services. Cities and towns typically contract with counties for police services or with neighboring cities or towns for services. The level of service and cost must be negotiated among jurisdictions. In contracting for police protection, a city or town may opt to appoint a city employee or officer to serve as a chief law enforcement officer, or, as is most typically done, designate an officer from the contracted jurisdiction to serve in that capacity.
Many local governments also enter into mutual aid agreements with other cities, the county, or the state patrol to provide back-up assistance in emergency situations.
This page provides examples of these and other types of agreements entered into by jurisdictions across the state.
