Nearly lost amid the sweeping roundup of more than 60 members of the Gambino crime family two weeks ago was the indictment of Anthony Delevescovo, director of tunneling for Schiavone Construction, which has $1.3 billion in contracts with the city’s Department of Environmental Protection, including more than $300 million for work at the DEP’s Croton Water Filtration Plant in Van Cortlandt Park.

For more than a year, as the filtration plant’s budget has ballooned to almost $3 billion, Assemblyman Jeffrey Dinowitz has hinted that there may have been criminal involvement in the siting of the project in Van Cortlandt Park – the only potential site where a nine-acre, 100-foot-deep hole was required.

Now, following the indictment of Delevescovo, Dinowitz has even more reason to be suspicious.

“Outrage over astronomical cost overruns on the project are well documented,” Dinowitz said in a statement recently. “But with the arrests of organized crime figures, including an executive of Schiavone Construction, one of the filtration project’s largest contractors, it is imperative that the public be fully apprised of the extent of the influence of organized crime.”

Dinowitz, who represents the area surrounding Van Cortlandt Park, has asked for full investigation by Bronx District Attorney Robert Johnson.

“We can leave no stone unturned in efforts to assure the public that this controversial project is 100 percent aboveboard,” Dinowitz said in his statement.

A DEP spokesman told the Daily News earlier this week that Schiavone has five contracts with the agency. “The DEP expects these important construction projects to continue on schedule. DOI [Department of Investigation] has advised that there is no reason to terminate the contracts as things stand now,” the spokesman said. “We will fully cooperate with any investigation.”
