The credibility of the Bloomberg administration is being questioned in a dispute over waterfront property in Brooklyn on which a developer wants to build a power plant. City Hall says this is all much ado about a typo.

Mayor Bloomberg opposes using the riverfront land for the power plant. He wants a 28-acre park that would complement his recent Greenpoint/Williamsburg rezoning initiative – a substantial development plan that seeks to transform the industrial area into a residential and commercial neighborhood.

The power plant developer, Adam Victor of TransGas Energy, accuses the city of negotiating in bad faith. His evidence is a city-ordered environmental report that refers to a “town home complex” on the site.

City officials say the reference to homes is a clerical error in a draft report and insist they have no plans for housing on the site. A spokesman for the city’s Department of Design and Construction, Matthew Monahan, pointed out that the final version of the study changed the language about homes to read “Williamsburg Park.”

“The draft in November had it incorrectly referenced,” Mr. Monahan said.

Mr. Victor insists the discrepancy between the proposed uses shows the city has been “disingenuous” about its intentions for the site.

City officials said yesterday that they have no intention to build “town homes” on the site, and that the discrepancy is due to a “typo” on the part of the environmental engineering firm undertaking the study, Metcalf & Eddy.

Mr. Victor, who has fought a persistent campaign to site an unpopular 1,100 megawatt power plant on the Brooklyn waterfront, provided the documents to The New York Sun. Recently, Mr. Victor received an unfavorable recommendation from a state board, reaffirming a ruling that the site is unsuitable for a power plant because of the city’s designs for the neighborhood. Mr. Victor has vowed to wage an expensive legal battle.

In an environmental study conducted by TransGas, the cost of cleaning up the contaminated site to build the power plant was $338 million. Mr. Victor said the city would be unable to build a park without revenues from selling the development rights for a high-end residential complex or other types of private investment, such as his $2 billion power plant project.

“I don’t think there has ever been a park in the history of the world where they spent $338 million to remediate 8 acres,” Mr. Victor said.

Developers have said there have been persistent rumors about building a marina near the TransGas site. The site is not currently zoned for residential, and would require a rezoning for any houses to be built.

The city has budgeted $100 million for the park and appropriated about $13 million for land acquisition this year.
