Intergovernmental Cooperation in Public Works

This page provides examples of intergovernmental cooperation in public works by local governments in Washington State. It is part of MRSC's series on Public Works Contracts and Intergovernmental Cooperation.


This page provides information on intergovernmental cooperation activities that provide innovative services, effective service delivery, cost savings, and/or other governmental efficiencies. For information on the Interlocal Agreement Act and more information about interlocal agreements, see MRSC's Interlocal Cooperation page.

Example Interlocal Agreements

Joint Utility Services Authority

Laws of 2011, ch. 258, RCW 39.106, created a new type of intergovernmental municipal corporation to improve the ability of local government utilities to plan, finance, construct, acquire, maintain, operate, and provide facilities and utility services to the public, and to reduce costs and improve the benefits, efficiency, and quality of utility services.

Agreements forming an authority must be filed with the Washington State secretary of state, which will provide a certificate of filing. An authority shall be deemed to have been formed as of the date of that filing. For articles and existing authorities see MRSC's page on Interlocal Cooperation.
