The Seattle SuperSonics have chosen the Seattle suburb of Renton as the site for a proposed $500 million multipurpose arena. King County Executive Ron Sims announced the choice Tuesday to state lawmakers.

"We in King County support this bill ... and are looking forward to working with the city of Renton," Sims said at the end of his testimony to a Senate Ways and Means Committee hearing on proposed bills that would authorize the use of King County taxes to build the facility.

"I don't want to see the Sonics or the (WNBA) Storm leave this community. They are very valuable to this community," Sims said. "These are quality-of-life investments."
