Factoria Transfer Station Replacement Project

Factoria Recycling & Transfer Station replacement project

Construction Update

Construction of the new Factoria facility began in September 2014 and was completed in September 2017. The station now accepts recyclable materials in addition to garbage, and household hazardous waste. Visit the Factoria Recycling & Transfer Station

The original Factoria Transfer Station was constructed in the mid-1960s. The new facility was built to provide 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.

In May 2016, the project reached a major milestone with the opening of a new 75,000-square-foot transfer building. New features include:

  • A larger transfer building which reduces customer wait times
  • Garbage compactors that have improved the efficiency of payloads and decreased the number of transfer trailer truck trips required to and from the station
  • An enclosed solid waste transfer building, with adequate roof clearance, that minimizes noise, dust and odors

As of October 1, 2017, the station now accepts the following recyclable materials:

  • 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

Public involvement

The public involvement process provided an opportunity for customers, area residents and other interested parties to learn about the facility replacement project and to offer comments on the planned improvements. Read the "Neighbor Newsletters" for information about construction activities.

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.

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 Factoria Recycling & Transfer Station attained a LEED™ Gold rating.

Some of the sustainable features of 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.
