This page provides a basic overview of interlocal law enforcement cooperation in Washington State, including examples of interlocal agreements between cities, counties, Indian tribes, or other government agencies.

It is part of MRSC's series on Intergovernmental 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.

Meanwhile, counties provide law enforcement through the sheriff's office.

Many small communities and even several larger ones enter into a contractual arrangement with another jurisdiction to provide law enforcement services. Cities and towns typically contract with the county for police services or they may also contract with a neighboring city or town for service. The level of service and cost must be negotiated between the jurisdictions. In contracting for police protection a city or town may opt to appoint a city employee or officer to serve as chief law enforcement officer or as is most typically done designate an officers from the jurisdiction being contracted with to serve in that capacity.

Many municipalities also enter into contracts with other cities, the county, or the state patrol to provide back-up assistance in emergency situations.
