SAN FRANCISCO (KPIX 5) — Even as support grows in San Francisco for a new waterfront arena for the Golden State Warriors, an overwhelming majority of San Franciscans want the arena project to be put to a vote, according to a Survey USA poll commissioned by KPIX 5.

72 percent of San Franciscans surveyed said the arena project should be placed on the ballot for voters to decide, with only 21 percent said it should not and seven percent were not sure.

Despite strong opposition and rising cost projections, 68 percent of those surveyed support the Warriors proposed building of an arena along the city’s waterfront, up from 59 percent in a KPIX 5/Survey USA poll in March of 2013.

The survey of 500 San Francisco residents said the site at the base of the Bay Bridge at Piers 30 and 32 remain the top choice as the future home of the Warriors. 34 percent favor the site over the 28 percent favoring the parking lot site across from AT&T Park.

Earlier this week it was revealed that the team had renewed talks with the San Francisco Giants to build next to AT&T Park.

Only 16 percent of residents favored a site in the Mission Bay neighborhood, with the rest indicating “other” or “not sure.”

Last month, team officials said that the planned facility at Piers 30 and 32 would not open as planned in 2017. Cost estimates have now doubled for renovating existing piers so that they can support the NBA arena.

At the same time, proponents of a ballot measure that could impact the arena plan by imposing tighter restrictions on waterfront development submitted signatures to the city’s Department of Elections.

Meanwhile, Oakland city officials have vowed to try and keep the Warriors in Oakland.
