Interlocal Agreements

Chapter 39.34 RCW, the Interlocal Cooperation Act, provides the authority for Washington State agencies to contract with other governmental entities. This law includes a requirement for filing agreements with the county auditor or publishing a list, by subject, on the agency’s web site.

The Utilities, Railroads, and Agreements office manages an agreement database and reports on Interlocal agreements for specific work groups within WSDOT. To comply with RCW 39.34.040, this office has elected to publish a list of Interlocal Agreements on this web page. This page is updated frequently with agreements either in development or in effect.
