The Washington State University forest will soon be replaced with the concrete jungle of a new Costco building.

Updates are few and far between, but commuters along state Route 410 will have noticed the skeleton of the building being erected over the past several weeks.

Peter Kahn, the vice president of real estate development at Costco, said the foundations and the steel structure of the building are totally finished.

Crews are still working on under slab utilities, which are about 70 percent complete, masonry walls, which are about 90 percent complete, and the fuel facility, which is only a quarter of the way finished, Kahn said in a Dec. 8 interview.

“Currently we are scheduled to be substantially complete this July,” Kahn continued. “Our targeted opening is currently July but if the city’s and the developer’s work is completed earlier in the spring Costco can be prepared to open earlier than July.”

The developer and city projects Kahn alluded to was the extension of 204th Avenue East to connect to the highway and more improvements to SR 410.

Visconsi is in charge of extending 204th Ave., and City Administrator Don Morrison said the city expects the road extension to be completed before April 1 of next year.

The city is in charge of highway improvements, “including the turning lanes, signals, controllers, and landscaped median,” Morrison said. “There was an issue with the exact location of landscaped medians, but that has been resolved. I anticipate all of the SR 410 work to be completed before the end of March.”
