The CRDA approved designation of the water park project as an entertainment retail district, which entitles it to an annual rebate of up to $2.5 million in sales tax generated by it for 20 years.

They are separate from the $100 million water park at the site which the agency approved for a tax incentive plan last December. Tuesday afternoon, a state agency, the Casino Reinvestment Development Authority, approved indoor and outdoor entertainment plans for the Showboat.
