South County Recycling and Transfer Station project updates

The existing 1960s-era Algona Transfer Station is one of the oldest, busiest transfer stations in the King County solid waste system. The station is located on a small site and offers only limited recycling services.

The new station will provide comprehensive recycling services, hazardous waste disposal, sustainable building features, offsite wetlands improvements, on-site creek enhancements, public art, and other community benefits.

Work on your new recycling and transfer station is underway

In May 2023, King County broke ground on a state-of-the-art recycling and transfer station just north of the existing Algona Transfer Station. The new station will replace the existing station and is scheduled to open to the public as soon as summer 2026. 

Upcoming work in 2024 includes construction on West Valley Highway South

Improvements to West Valley Highway South: Work is expected to begin as early as late May and last through October.

Work may include temporary lane closures and detours. We will communicate details as construction nears.

New culvert under West Valley Highway South: Work is expected to begin and finish in July.

Upgraded sewer line on 11th Avenue North: Work is expected to begin as early as July and last through September.

Early site work completed

Construction crews have completed initial work to survey and prepare the
site, including:

  • Site retaining walls to maintain soil integrity and prevent erosion.
  • One of three stormwater retention vaults to manage stormwater runoff.
  • Habitat improvements including a new stream channel and uncovering
    a tributary of Algona Creek that was previously piped underground.
  • View real-time images of construction progress at

King County will work with the community to minimize construction impacts

During construction, people who live, work, and travel in the area can expect occasional noise, vibration, and dust near the construction site. Crews will make every effort to limit the effects of construction on the surrounding community.

King County is committed to being a good neighbor and will work directly with the community throughout the project to minimize impacts whenever possible. Residents can expect:

Recycling made easier, powered by the sun

The new recycling and transfer station will make it safer and easier to recycle appliances, glass, metals, plastics, wood, and paper; compost yard waste; and dispose of hazardous materials.

The new station is designed to meet Living Building Challenge standards, creating a positive impact on the human and natural systems that interact with it. The green design includes solar panels that will provide nearly half of the energy needed to operate the
station, electric vehicle charging stations, and habitat enhancements. We will also improve nearby green spaces, plant trees and establish a forested buffer zone around a newly uncovered tributary of Algona Creek.

Creating a positive impact with modern design

The new station’s modern design elements will address many challenges that are encountered at older stations.

Controlling Air and Odor
The walled-in structure will contain air flow and hold in odors, while misters will additionally suppress odors and dust.

Natural Lighting
Windows and roofing will use transparent materials to let in natural light and reduce electricity costs.

Containing Sound
The enclosed structure, sound absorbing landscape, and distance surrounding the facility will reduce noise from equipment and vehicles.

Mitigating Traffic
Trash compacting equipment will allow more waste to be hauled in fewer trips, reducing the number of trucks coming to and from the site; additional driving lanes will allow vehicles to move through the site more quickly.

Investing in Meaningful Community Art

Artists Tyson Simmons, Keith Stevenson, and Sam Obrovac of the Muckleshoot Indian Tribe’s Culture Division will create a signature sculpture carved from trees felled on the project site as well as concrete patterning and aluminum medallions for the entry retaining wall. Both artworks reference Muckleshoot stories of air, land, and sea, representing ancestral teachings about the interconnectedness of the world around us.

Evan Blackwell, visual artist and faculty member at Evergreen State College, is developing a body of work informed by engagement activities and materials sourced during a multi-year residency. Select pieces will be installed in the lobby of the South County Recycling and Transfer Station administrative building and in the surrounding landscape.

Improving Signage on the Interurban Trail

The Solid Waste Division is working with King County Parks and Recreation staff, the cities of Algona, Pacific and Auburn, and other organizations to develop new signage to enhance your experience on the trail. These new signs will provide information such as distance to the nearest rest stop, the locations of public restrooms, facts about local wildlife, and the area’s history.
