Memorial Stadium Construction

Construction Update

The redevelopment of Memorial Stadium is a legacy project to better serve the needs of future generations of SPS students and maximize its use for the community in new and different ways.

With the construction phase underway now through 2027 – led by construction partner Sellen Construction – we will provide regular project updates via this website, campus signage, digital alerts, and monthly project email updates available upon request at MemorialStadium@sellen.com. In addition, Seattle Center will continue to coordinate updates with partner/resident organizations and event partners, and will post construction alerts and signage on campus.

Construction Schedule

Construction work hours are currently scheduled for 5 a.m. to 1:30 p.m. on weekdays in accordance with site logistics and permit approvals. This activity will result in noise from vacuum excavator trucks, saw cutting, core hole drilling, dump trucks, and other heavy equipment.

Upcoming Construction Activity & Neighborhood Impact Updates

Beginning July 1, 2025, the Memorial Stadium team will establish construction boundaries around the project.
Beginning July 7, 2026, removal of the existing field, soft demolition and abatement will begin.
Structural demolition is scheduled to begin during the third week of July, once the Memorial Wall has been fully protected.
As part of the construction of a new Memorial Stadium, a number of trees within the construction zone are being removed. This work is a necessary and carefully planned part of the project and has been reviewed and approved through the City’s permitting and environmental processes. Learn more about tree sustainability including tree preservation, tree replanting, tree offsets, and the new tree canopy as part of the new landscape design.
