HARTFORD — Gov. John G. Rowland said Wednesday that his administration is evaluating New Haven’s latest four-year, $100 million downtown redevelopment concept but hasn’t made any commitments yet.

"The whole thing about New Haven, I mean, that’s on the back of an envelope," Rowland said. "There’s been no proposal, there’s been no hearings, there’s been no discussion, there’s nothing on paper."

The governor’s comments were made while he was discussing the state’s ongoing budget difficulties and the fact that the legislature still needs to approve a two-year state borrowing plan to pay for all kinds of municipal and state projects.

"I think it’s very fair for the governor to acknowledge that these are tight financial times and that the state needs to carefully evaluate every bonding request," said New Haven Mayor John DeStefano Jr.

The city’s economic development administrator, Henry Fernandez, said city officials expect to provide Rowland’s staff with details and figures on the new redevelopment plan by early next week.

Fernandez said New Haven officials are expecting to ask for less than $10 million in state bond grants in this fiscal year to tear down the Veterans Memorial Coliseum. DeStefano said city officials decided not to try and get any commitments for that money during the recent partisan battle over a two-year state budget.

Fernandez said the city’s four-year, $100 million request isn’t out of line with past state funding levels for urban projects around Connecticut. "We don’t think those are crazy numbers," Fernandez said.

Rowland said he was briefed about a month ago on the city’s downtown redevelopment wish list.

Fernandez said that plan includes tearing down the coliseum, creating a new parking facility, hotel and conference center complex and moving the Long Wharf Theater downtown.

But the governor sounded skeptical about proposals for allocating $140 million in state funds to move Gateway Community College to a new downtown campus building.

"I don’t know who made those numbers up, but there’s a whole process to follow… to determine what priorities we should take each year" for the community college system, Rowland said.

"We generally spend about $80 million per year on the community college system," said Rowland. "So to suggest $140 million—even the (renovation of the Capitol Community College’s new headquarters in Hartford at the old) G. Fox building, that was half that amount."

DeStefano said the $140 million cost estimate "is the state’s number." He said city officials feel "very confident about where we are in determining the right number for Gateway… We’ll work that out."
