Factoria Transfer Station Replacement Project

Construction Update

Construction of the new Factoria facility began in September 2014 and is expected to last until late 2017.  The station will remain open to customers throughout construction. See the project schedule or read the "Neighbor Newsletters" for information about past, present, and future construction activities.

Enclosed transfer building

The original Factoria Transfer Station was constructed in the mid-1960s. The facility is currently under construction and is being replaced with a larger, modern facility built to meet current building and environmental standards and to accommodate projected future growth in the region. The Factoria Transfer Station is located in a light industrial area approximately one half mile north of Interstate 90 and one half mile east of Interstate 405.

The station currently accepts garbage and household hazardous waste – in a designated drop off area.

In May 2016, the project reached a major milestone with the opening of a new 70,000-square-foot transfer building. New features include:

  • A larger transfer building which reduces customer wait times
    Both self-haul and commercial customers now have ample room to unload.
  • A garbage compactor has improved the efficiency of payloads and decreased the number of transfer trailer truck trips required to and from the station
    The addition of garbage compactors at the station has resulted in 500 fewer transfer trailers needed to transport the garbage to the landfill on local roadways in just six months.
  • An enclosed solid waste transfer building, with adequate roof clearance, that minimizes noise, dust and odors

Future improvements (coming in late 2017) will include:

  • Recycling collection areas for:
    • Major appliances (refrigerant and non-refrigerant type)
    • Clean wood (unpainted, untreated, unstained)
    • Comingled recyclable materials (aluminum and tin cans, cardboard, glass bottles and jars, paper, and plastic containers such as bottles, cups, jugs, tubs and plant pots)  
    • Scrap metal
    • Textiles
    • Yard waste
  • A new building dedicated to collection of household hazardous waste.
  • Sustainable building design features that will improve energy efficiency and result in lower life cycle costs than a conventional building design
  • Sufficient space to process projected future volumes of solid waste and to expand recycling as needed

Purpose/Action Taken

May 12, 2010

An open house and presentation on the project was held at the East Shore Unitarian Church. This meeting was an opportunity for facility neighbors, customers, and others to learn about the project and give input on the service and facility improvements considered for the station.

Summer 2010

Preparation of a Draft Facility Master Plan

Sept. 30, 2010

King County Solid Waste Division issues a “Determination of Nonsignificance Non-Project Action” and issues a Draft Facility Master Plan for public review

Oct. 18, 2010

Comment deadline on the Determination of Nonsignificance

Fall 2010

Facility Master Plan submitted to King County Council

April 2011

King County Council approved the Facility Master Plan

Aug. 17, 2011

A community meeting was held to provide facility neighbors, customers, and others with an update on the project.

March 8, 2012

The King County Solid Waste Division issued a Mitigated Determination of Nonsignificance (MDNS) per the State Environmental Policy Act (SEPA). This determination means that the proposed facility replacement project does not have a probable significant adverse impact on the environment. This decision was made after review of a completed environmental checklist, technical discipline reports, and other information on file with the lead agency. The MDNS outlines mitigation measures that will be implemented to avoid, minimize, and compensate for negative impacts to the built and natural environments. View the “Project SEPA – March 2012” documents below.

April 9, 2012

The King County Solid Waste Division submitted an application for Conditional Use Permit and Critical Areas Land Use Permit approval to remove the existing Factoria Transfer Station and construct a new transfer station and recycling areas with associated facilities.

Sept. 6, 2012

The City of Bellevue held a public meeting to receive comments on the Solid Waste Division’s application for Conditional Use Permit and Critical Areas Land Use Permit

Dec. 13, 2012

City of Bellevue held a Public Hearing on the Solid Waste Division’s proposed project and recommended approval, with conditions, of the Division’s Conditional Use Permit and Critical Areas Land Use Permit application.

2011 – 2013

Environmental review, facility design, land use permitting and construction procurement

Sept. 2014

Construction of new facility begins

Sept. 2014 – late 2017

Ongoing construction of new facility

May 2016

New 70,000-square-foot transfer building opens to the public

Late 2017

Construction completed. Recycling services will be available and the new building to receive household hazardous waste will open.

Note: The Solid Waste Division plans to continue operating the existing facility while the new facilities are constructed. However, customer access to the facility may be periodically interrupted during construction. If so, customers will be re-directed to the closest county transfer station.

The LEED™ Green Building Rating System™ recognizes environmental leadership in the building industry. It is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. LEED™ emphasizes state-of-the-art strategies for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. Projects can obtain various levels of certification including Certified, Silver, Gold, or Platinum - based on a point rating system. The goal of the Factoria Transfer Station replacement project is to attain a LEED™ Gold rating.

Some of the sustainable features being considered for the new station include:

  • Recycled content building materials – in building walls, floors, roof and other areas
  • Rainwater harvesting – collecting and storing rainwater for use in washing down station floors and equipment, and for flushing toilets
  • Passive ventilation
  • Efficient energy usage
  • Natural daylighting - using translucent windows to allow natural daylight to light work areas as much as possible
  • Efficient water usage within the building and for landscaping

These features are consistent with the Solid Waste Division's environmental focus and with King County's "Green Building Initiative" that promotes the use of environmentally responsible construction practices in all of the County’s building projects. The green building practices applied to this project are also expected to result in lower life cycle costs than in more conventional building designs.

Public art

In 1973, King County adopted legislation creating the 1 Percent for Art Program. The program requires that 1 percent of funds from capital construction projects be set aside for public artwork. Experience has shown that investments in public art benefit the community in many ways, from deterring vandalism to turning public facilities into better neighbors and community assets.

The artwork for the project will likely reflect a solid waste or recycling theme and will help promote greater public awareness regarding solid waste issues. The artist selected for the Factoria Transfer Station Replacement Project is Al Price of Phoenix, Ariz. For information about Mr. Price’s work, please visit the 4Culture website below.

Public art associated with King County construction projects is managed by 4Culture, the county's cultural services agency. 4Culture ensures that the work of artists is reflected in the built environment, bringing art into the everyday lives of visitors and residents. More information about the agency can be found at (external).
