Two separate groups proposed renovation plans for KeyArena in Seattle with the hopes of luring NBA and NHL teams.

The Oak View Group (OVG) unveiled a $564 million renovation plan Wednesday, and Seattle Partners — a group formed by Anschutz Entertainment Group (AEG) and Hudson Pacific Properties — unfurled its own $520 million proposal.

Both groups expect the arena to be ready in time for the 20-21 season.

“We’re going to do this and stand on our own two feet,’’ Oak View Group CEO Tim Leiweke said of his arena plan, which includes 18,350 seats for NBA games, 17,100 for NHL contests and 19,100 for concerts. “And we believe by doing that we give Seattle its best chance at getting one or two teams.’’

City of Seattle officials will study the proposals, which were due Wednesday, decide which is more viable and submit a decision to Mayor Ed Murray by late June.

Seattle could still move forward with an arena in the Sodo district headed by Chris Hansen.
