The chairman of a key Baltimore City Council committee said yesterday that he has strong reservations about the city's plans to publicly finance and own a convention headquarters hotel and wants an independent commission to review proposals rejected earlier by the city's economic development agency.

Keiffer J. Mitchell Jr., chair of the taxation and finance committee, wants an independent commission to re-evaluate all three bids submitted to Baltimore Development Corp., including plans for a hotel that would not have required full public financing.

City officials say the city needs a four-star hotel adjacent to the Baltimore Convention Center to boost flagging business at the center and compete for conventions with Philadelphia, Boston and Washington.

In what would be one of the most expensive city projects ever, BDC plans to seek approval from the City Council and Board of Estimates for about $290 million in tax-exempt revenue bonds to finance construction and other costs for a 750-room Hilton. The hotel would be built on an empty parcel just north of Oriole Park at Camden Yards, with a goal of opening in 2008.

"This has raised a few red flags for me," said Mitchell, whose committee would have jurisdiction over the bill. "Obviously, the main one is, should the city be in the business of running and operating its own hotel, with 100 percent public financing. We're going down a road that the city hasn't gone down before."

Mitchell said he doesn't question that the city needs a convention hotel, only whether it has to be wholly publicly financed. "There are people [developers] out there who I think would put their money into a convention center hotel," he said.

The vice chairman of the committee, Councilwoman Helen L. Holton, also raised concerns about the way the city plans to get the hotel built.

"I understand the need for us to have a headquarters hotel, but we're not developers, we're government," she said. "I'd rather be the landowner and have someone else develop the hotel and take on the responsibility of making sure the debt is repaid."

M.J. "Jay" Brodie, president of BDC, said the city has no alternative.

"If there were another way to do it, we would be proposing it. We have concluded there is no other way to do it. It's not that we've reached this conclusion lightly or by ourselves."

He noted that other cities, such as Denver, have concluded that private equity is not available for major downtown convention center hotels.

Brodie said BDC is working with the Wall Street firm Piper Jaffray to secure an investment-grade rating for the bonds and win a favorable interest rate, possibly less than 5 percent.

"The ability to achieve that rate that has driven these deals in other cities," Brodie said. "No private entity can get anything like that rate."

A spokeswoman for Mayor Martin O'Malley said Brodie was also speaking for the mayor.

The city is pushing ahead with plans for the hotel at a time when publicly financed convention hotels around the country - including hotels in Myrtle Beach, S.C.; St. Louis and Sacramento, Calif. - have failed to meet projections as cities race to expand convention facilities while convention business is static.

The 404-room Radisson Plaza Hotel Myrtle Beach Convention Center, which opened in January last year, fell far short of forecasts, leading to a technical default in April on the city's hotel bonds and an operating loss of $1.75 million for fiscal 2004.

When convention bookings in St. Louis failed to live up to projections, the 1,000-room Marriott had to dip into cash reserves to pay its debt.

A new 500-room Sacramento Grand Sheraton, built with $92.9 million in bonds backed by operating income from the hotel and an adjacent garage, has boosted convention business by less than a third of the 60,000 hotel nights a consultant projected.

More than a year ago, BDC selected a development team headed by Robert L. Johnson, the founder of Black Entertainment Television, which will have no equity stake in the hotel, to be operated by Hilton Hotel Corp.
