Panattoni Plans 1.03 Million-Sq-Ft Warehouse on 66-Acre Wild Waves Site

May 13 filings with Federal Way show Panattoni Project Podium would clear the entire Wild Waves property and build a 1,035,000-square-foot, one-story warehouse with truck loading and trailer storage.
The redevelopment follows Wild Waves' planned permanent closure after the 2026 season, which operator Premier Parks tied to rising costs and millions of dollars in losses since reopening after COVID-19.
The 66-acre project near Interstate 5 is expected to be 98% warehouse and 2% office space, stand about 46 feet tall, and reach full buildout in 2028.
Traffic studies estimate 1,517 weekday vehicle trips, including 445 truck trips; plans add three Milton Road South driveways and convert 19th Way South and South 369th Street to an all-way stop.
Local opponents say replacing the 1977 amusement park with a warehouse would strip Federal Way of a family attraction despite proposed landscaping, trees and fencing to screen the site.
