 Port Quendall, a land parcel in north Renton, is home to the Virginia Mason Athletic Center (VMAC), housing the Seattle Seahawks Headquarters and training facility that opened in August 2008; before then, the Seahawks trained in Kirkland.In the mid-1990s, Renton undertook a major redevelopment effort to revitalize its downtown core, which had declined in commercial prominence since the opening of the Southcenter Mall in Tukwila in 1968.The many car dealerships that had previously occupied the center of downtown Renton were encouraged through economic incentives to relocate to a newly created auto sales zone close to the I-405/SR-167 interchange.
