Join employees from the King County Solid Waste Division (SWD) at two upcoming public events that are focused on the County’s Cedar Hills Regional Landfill in Maple Valley.

The SWD is offering a guided, 90-minute tour of the 920-acre landfill on at 9 a.m. on Saturday, Oct. 15.

“Tour participants will see how this modern facility responsibly manages and creates resources from the roughly 900,000 tons of solid waste it receives each year, and how recent investments support our ongoing efficient and safe landfill management,” said SWD Director Pat McLaughlin.

Reservations for the tour are required, and can be made by calling 206-477-4466, TTY Relay: 711 by Oct. 10. Parking is provided at the landfill, 16645 228th Ave. SE, Maple Valley, and participants will board a Metro bus for the guided tour. The bus is wheelchair accessible.

To ensure safety, tour participants must wear closed-toe footwear and adhere to all traffic signs at the landfill. The landfill tour is designed for adults and families with children aged 5 and older.

On Tuesday, Oct. 25, the SWD hosts its regular community meeting for all who are interested in discussing current and planned activities at the landfill.

The meeting is set for 7:30-9 p.m. at the Issaquah Library, 10 W. Sunset Way, Issaquah, and will include a presentation by representatives from Bio Energy Washington, the company that owns and operates the landfill gas-to-energy plant at Cedar Hills and generates clean, renewable natural gas from landfill gas.

Community meetings are a cornerstone of the division’s ongoing commitment to meet with landfill neighbors on a regular basis. Accommodations will be provided when requested at least one week in advance. Please call 206-477-4466 for more information.
