The board has addressed the concern over cost by scaling back the square footage of the project, Boepple said.
"We've taken out things our theater consultants told us were not essential, like lots of offices," she said. "It's easier and cheaper to rent offices in the surrounding area. We also took out a floor that would have been a rental floor for parties."
She said the adjustments "bring the cost down to something that is realistic."
"I don't know what the final number will be but it will be money that we believe we can raise," said Boepple, adding that it will be below the initial estimate of $400 million to $500 million.
Architect Frank Gehry was retained in 2006 to develop a world-class facility that could host and produce a range of performing arts.
It will present theater, dance and music from around the globe and produce work from young artists, composers, choreographers and playwrights," Boepple said.
The Joyce Theater, which presents dance, is expected to become the anchor tenant of the center.
Gehry's preliminary design calls for a 1,000-seat theater, a secondary 200-seat theater, rehearsal spaces and cafe, among other features.
One of the obstacles to construction has been the temporary Port Authority Trans Hudson train station entrance that occupies the space of the future center.
The entrance was created to provide access to the transit center that was badly damaged and flooded during the terrorist attacks.
The above-ground construction will start as soon as the temporary entrance to the PATH train station at the site is relocated, Boepple said.
