NORTH HILLS – Deepdale Golf Club is a private 175-acre golf course. And it wants it to stay that way.

Deepdale attorneys filed federal and state lawsuits Tuesday to prevent the Village of North Hills from seizing the property – whose membership roster is said to include Michael Bloomberg and fashion designer Oleg Cassini – and turning it into a private club for village residents.

The move, which the plaintiffs said will cost more than $100 million, would create an amenity that could boost property values in the wealthy Nassau village, according to village officials. Mayor Marvin Natiss said the plan is only being considered, and no appraisals have been viewed.

Natiss called the lawsuits a “double-barrel action” designed to intimidate the mayor and trustees. “The said they’ll make it ugly, and they’re making it ugly,” he said of the people behind the suits.

The Manhattan firm of Wachtell, Lipton, Rosen & Katz filed the federal suit for Deepdale Inc., alleging this case of eminent domain would be “unconstitutional and unlawful.”

U.S. Supreme Court ruled in June 2005 that local governments may use eminent domain, seizing private land for public use in order to reinvigorate a blighted area. The firm realizes that, but taking a private course for village residents should not be permitted, said firm partner Theodore Mirvis. There’s “no conceivable need for this golf course” he said. “There’s nothing distressed in North Hills.”

North Hills has been ranked as the single wealthiest community in the Northeastern United States, the suit states. It also points out there is a public golf course two miles east and a North Hempstead course is just three miles from North Hill’s center. The private North Hills Country Club, meanwhile, is 250 yards from Deepdale.

Finally, the suit alleges North Hills plans to sell a “substantial portion” of the course to a private developer to build pricey high-density condos.

“Private greed,” the lawsuit says, “Is not a public purpose.”

Ruskin Moscou Faltischek handled the state suit, filed on behalf of Deepdale member and North Hills resident John Wilson, labeling the move as a “perversion of purpose in the incentives zoning law.” The suit accuses North Hills’ mayor and trustees of cutting “back room” deals with developers to receive zoning bonuses in exchange for multi-million dollar payments. That let them “amass a fund to defray the cost of their illegal plan to acquire the Deepdale Golf Club through eminent domain.”

Naitss said that is not true. “I’ve never met with any builder or developer in connection with Deepdale,” he said. “We basically want to keep it as open space and recreational facility for village residents.”
