Solid Waste Division celebrating 50 years of operations at Cedar Hills Regional Landfill


To commemorate 50 years of operations at the Cedar Hills Regional Landfill in Maple Valley, the King County Solid Waste Division invites the public to come tour the facility, hear from division and County leadership, and enjoy informative displays.


For the past 50 years the Cedar Hills RegionalCHRL_50th_Landfill_Tours Landfill in Maple Valley has served as King County’s primary solid waste disposal location.

To celebrate the life of the landfill and the services it continues to provide, the King County Solid Waste Division is hosting an event on Saturday, April 23 from 10 - 11:30 a.m., when the public can learn about where their waste goes. 

This commemorative event offers the public a chance to tour the landfill and see how its modern design allows the Solid Waste Division to collect and transmit landfill gas to the onsite BioEnergy Washington plant for processing into renewable energy.

Guests will also get to see landfill heavy equipment and learn how the Solid Waste Division continues to be a national leader in waste prevention, resource recovery, and waste disposal. 

In addition to the tour, King County Deputy Executive Fred Jarrett and other county leaders will speak about the importance of the landfill to the county’s residents and to the county’s efforts to combat climate change.

Reservations are required and must be made by April 18. This is a great learning opportunity for the whole family – children ages 5 and over are welcome to join if accompanied by an adult. Please note that space is limited to 108 people.
Parking will be provided at the landfill and participants will board a King County Metro bus for the guided tour. The buses are wheelchair accessible. To ensure safety, tour participants must wear closed-toe footwear and follow instructions from employees.

To RSVP for the event, or to request accommodations or an interpreter, contact King County Solid Waste Division Communications Specialist Anna Kegel, 206-477-1693 or
