Construction is currently under way for the Memorial Stadium redevelopment project, with completion planned for Fall 2027.

The project, operated under a not-for-profit model managed through a partnership between Seattle Public Schools (SPS), City of Seattle (City), and One Roof Sports & Entertainment, will create a state-of-the-art multi-purpose stadium for student athletics, education, arts, culture, entertainment, and community events. It will be seamlessly integrated with the Seattle Center campus, and will continue to inspire students, the community, and the region for generations to come.

In addition to an improved athletic field, the shared vision for this dynamic new state-of-the-art stadium will center on students with performing arts, commencement ceremonies, and social and educational opportunities, as well as provide a welcoming year-round hub for community events. The new stadium will be a win for students, Seattle Center, and for the community.

One of Seattle’s most anticipated construction projects is also one of the greenest. In addition to a myriad of sustainability components integrated into the new stadium design, chief among these efforts is the onsite concrete processing plant, established on what was the historic Memorial Stadium field to crush rubble from the existing structure into backfill material for the new stadium.

While using recycled concrete is a cost-effective alternative to traditional soil backfill – and is common in construction – an onsite concrete processing plant is not a typical approach due to the space required but the Sellen Construction team’s creative use of the existing field space made it possible for this project, resulting in several benefits including reduced traffic and emissions impact.

Onsite processing is minimized reduced large-truck traffic impact to the surrounding neighborhood and minimized the need to haul materials offsite and bring in new backfill. This led to less idle equipment time, reduced emissions, decreased wear on nearby streets, and few traffic impacts.

Furthermore, by avoiding the need to export rubble and import new backfill, the project is saving $60 per ton. With 13,000 tons of repurposed material that adds up to around $780,000 in savings.
