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 will help 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.
King County Wastewater Treatment Division completed construction of the new Loop Vehicle Maintenance Facility located at 47009 SE 144th, North Bend, WA 98045. The 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.
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.
The Loop Vehicle Maintenance Facility will help 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. It can be challenging for Loop trucks transporting biosolids to forestry projects within King County and agricultural projects across the state to work within that hourly limit.
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 is pursuing LEED Platinum Certification, which means the facility will improve efficiency, lower carbon emissions and create a healthier workplace. Certification will be completed in 2023. Additionally, reducing truck traffic in congested areas near the former site at the airport will also help reduce carbon emissions.
