They hope to start construction on WarHorse Casino next year.
The existing planned-use development designation calls for 1.3 million square feet of commercial space. That would be reduced to 980,000, which includes the roughly 225,000-square-foot casino.
The proposed changes also would include the potential for 650 hotel rooms and up to 700 dwelling units.
The casino would have more than 1,200 gaming stations, a convention/event space, several restaurants and other amenities such as a spa.
The zoning changes include waivers for the height of the casino, apartments and hotel. Developers also want to combine space now allowed for multiple free-standing signs into one large sign that would face U.S. 77.
Other potential development in the area could include apartments, at least one other hotel and service-type commercial uses such as a convenience store and additional restaurants.
There will be little impact to traffic on West Denton Road because most of the traffic for the casino will come from U.S. 77 onto the still-to-be-constructed South First Street, said Andrew Willis, an attorney representing the developers. A roundabout will be built on South First Street.
City Councilwoman Sändra Washington raised concerns about water quality with regard to horse barns being built for the racetrack.
