Project update

Summer 2018

Wondering what the new facility will look like? Here is our current rendering:

Rendering of the Loop Vehicle Maintenance Facility

King County began the process to obtain construction permits. Permitting may take longer than originally anticipated. A new completion date will be updated as soon as we know more.

What is the Loop Vehicle Maintenance Facility Project?

King County Wastewater Treatment Division (WTD) is designing a new vehicle maintenance and staging facility for transporting Loop biosolids. The new facility will be located in North Bend (exit 34 off I-90) on County-owned land.

Why is King County building this facility?

  • The current vehicle facility is located in south Seattle, on a space leased from the King County Airport. The lease on this land is now ending without the option to renew, requiring WTD to relocate the facility.
  • Helps meet new federal regulations that limit the time a driver can be on the road.
  • This facility reduces driving time and improves safety for every traveler on our highways and roads.

What are Loop biosolids?

Loop biosolids are a nutrient-rich soil amendment created from King County wastewater. As it has for 40 years, the County produces Loop from solids extracted during the wastewater treatment process. Loop is used on farms and forests by commercial growers in both Eastern and Western Washington.

Project schedule

The County will design and construct the new facility in three phases. The facility is expected to open in 2019. The design phase began in fall 2016 and will continue through winter 2018. This phase includes acquiring permits, creating detailed design and engineering specs for the new building, and determining details about how the facility will look. During this phase the County will solicit input from the public on some elements of the facility design.

PLANNING
Fall 2016 – Winter 2016
DESIGN
Winter 2016 – Winter 2018
CONSTRUCTION
Winter 2018 – Spring 2019
FACILITY OPEN
  • Study site conditions (plants, animals, soils, cultural resources, topography, etc.) to determine if there are specific site constraints
  • Begin preliminary facility design
  • Acquire necessary permits and complete required environmental review
  • Work with neighbors and the community to understand needs and constraints during construction and facility operation
  • Gather public input on some project elements. Specific topics for community feedback are being identified, but could include choice of plants for landscaping and color of building
  • Design the facility structures
  • Hire a construction contractor
  • Build the new facility
  • Work with neighbors and the community to provide progress updates and notice of construction
  • Staff a 24/7 hotline during construction
TBD

Working with the community

King County will work with the public, community groups, and other key stakeholders to provide project information, identify potential impacts, and involve the community in project design where possible.

Community members can expect:

  • Advanced notice of meetings and construction
  • Community group and neighbor briefings
  • Project newsletters and fliers
  • Project web page updates, including frequently asked questions
  • Construction hotline
