A pair of projects that could profoundly change Atlantic City’s Chelsea section edged closer to construction Monday, as the Casino Reinvestment Development Authority gave zoning-related approvals for developments at and around the former Atlantic Club.

CRDA, which enforces zoning and land use for property within Atlantic City’s Tourism District, on Monday paved the way for the former casino to be converted into a family-focused entertainment complex with an 81,000 square-foot waterpark and about 800 hotel rooms.

The casino closed in January 2014. Three more Boardwalk casinos went belly-up later that year.

“This is really the first purposeful re-creation of a casino site into a noncasino attraction,” said board Vice Chairman Robert Mulcahy III. The company behind the project — Devon, Pa.-based Endeavor Property Group — says the $150 million to $165 million project could be completed in the winter of 2016-17.

A redevelopment plan for a separate project, on 14 nearby acres at the foot of Albany Avenue, also received the go-ahead from CRDA on Monday.

That project, called “Gateway,” is the first undertaking of AC Devco, the recently-formed CRDA-funded nonprofit aimed at accelerating development in Atlantic City. Mayor Don Guardian said the plan calls for “corporate offices and potential academic use” of the land, which includes the site of the former Atlantic City High School.

He declined to comment on whether Stockton University wants to open a facility there.

A spokeswoman for the university could not be reached for comment
