The Golden State Warriors have put on hold their goal of opening a waterfront arena in San Francisco by 2017. They will postpone the plans for one year and maybe longer.

"It's about getting it right, not about getting it done fast," Warriors president Rick Welts said.

The Warriors have produced three rough designs for the arena to come up with one to receive clearance from prospective neighbors and the Bay Conservation and Development Commission. Cost estimates for preparing Piers 30-32, on which the arena would sit, have doubled to $180 million.

The Warriors acknowledge a 2017 opening for the arena will not happen.

Arena opponents are expected to turn in more than 15,000 signatures for a measure that would require the Warriors -- and any other developer -- to win voter approval to exceed current height limits along the waterfront. The deadline is Monday.
