Special Purpose Districts - Table of Contents

In Washington State, special purpose districts are limited purpose local governments separate from city, town, or county governments. Generally, they perform a single function, though some perform more than one. They provide an array of services and facilities including electricity, fire protection, flood control, health, housing, irrigation, parks and recreation, library, water-sewer service, and, more recently, stadiums, convention centers, and entertainment facilities that are not otherwise furnished by city or county governments.

Over the years, the Washington legislature has enabled more than 80 different special purpose districts. The number of special district statutes vary depending on the definition of "special district."

Once thought of as existing only in unincorporated portions of counties, many district statutes allow the inclusion of cities and towns as well. Some districts have provisions for county-wide districts, some are multi-county, and others provide for interlocal cooperation.

The pages below provide an overview of special purpose districts, including information on their formation and dissolution, elections, and lists of existing special purpose districts and types.
