RCW 39.34 permits a local government to enter into interlocal agreements with other public agencies in the interest of cooperatively sharing resources for their mutual benefit. In accordance with RCW 39.34, Grays Harbor Communications has executed interlocal agreements with other public agencies for various purposes over the years.

Effective June 7, 2006, RCW 39.34.040 was amended to permit a public agency to list interlocal agreements on its website in lieu of having the agreement filed with the county auditor's office.

The interlocal agreements shown below are posted here to comply with RCW 39.34.040 and they have not been recorded with the Grays Harbor County Auditor's Office (Original interlocal agreements are on file with the Grays Harbor County Clerk and may be accessed by public disclosure request.)
