Interlocal agreements

View the interlocal agreements that the King County Solid Waste Division has with other public agencies. These agreements allow local government agencies to share resources for their mutual benefit.

Revised Code of Washington (RCW) laws

RCW 39.34 permits a local government to enter into interlocal agreements (ILAs) with other public agencies in the interest of cooperatively sharing resources for their mutual benefit. Under RCW 39.34 , the King County Solid Waste Division has executed ILAs 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 ILAs on its website instead of having the agreement recorded with the county auditor’s or recorder’s office. 

The ILAs posted here comply with RCW 39.34.040 and have not been recorded with the King County Recorder's Office. The original ILAs are on file with the specific county agency that is a party to the agreement. 

Use the Recorder’s Office online search tool to view recorded ILAs.
