Loop® vehicle maintenance facility
King County has completed construction of a new vehicle maintenance and staging facility in North Bend for transporting Loop biosolids.
Completed – Fall 2022
Project description
The vehicle maintenance and staging facility allows staff to maintain and stage vehicles that deliver nutrient-rich biosolids created from the wastewater treatment process to WTD’s forestry and agriculture customers in the Snoqualmie area and Eastern Washington. The facility helps meet federal regulations for driving time to keep drivers and the public safe by reducing driving time to no more than 11 hours per day.
The new Loop Vehicle Maintenance Facility is located at 47009 SE 144th in North Bend.
After receiving its certificate of occupancy from the City of North Bend in November 2022, WTD relocated its Loop vehicle maintenance operations from the former site leased at the King County Airport in the Georgetown neighborhood of Seattle to the new 12,500 square feet facility in North Bend. The former site lease at the airport ended without the option to renew, and thus WTD relocated to County-owned property in North Bend.
Loop biosolids are fully contained and enclosed within the trucks and will not be processed at this site.
The facility has three truck bays.
The facility maintenance building includes three truck bays, parking, equipment storage, landscaping and fencing. The project team used feedback collected from the community to guide the final design of the facility, including the color of the building and its landscaping. We planted native trees such as western red cedar and shrubs including vine maple, cascara, and pacific rhododendron.
About 14 Loop vehicles and drivers will use the facility to maintain and stage vehicles on a typical day. Normal hours of operation will be between 6 a.m. and 6 p.m. daily. However, there will be activities at the site 24 hours daily due to trucks arriving from trips at different times of the day.
The Loop Vehicle Maintenance Facility achieved LEED Platinum Certification, which means the facility improved energy efficiency, lower carbon emissions and created a healthier workplace. Additionally, reducing truck traffic in congested areas near the former site at the airport will also help reduce carbon emissions.
