The Solid Waste Division (SWD) maintains responsibility for nine landfills located throughout King County – seven of these landfills remain in custodial care with regular monitoring. These landfills include Cedar Falls, Duvall, Enumclaw, Hobart, Houghton, Puyallup/Kit Corner, and Vashon.

Landfills undergo routine monitoring of groundwater, surface water, wastewater, and landfill gas as needed. They are closed to the public, except at select landfills where some public activities are compatible with the ongoing maintenance activities.

A variety of documents related to King County's closed landfills are available through the King County Library System. Call the library's Answer Line at 425-462-9600 or 1-800-462-9600, or view a list of documents online external link to determine which library offers the documents that most interest you.
