Since 2015, developer EHB Cos. has tried to construct residences on the defunct Badlands golf course near Summerlin. Neighbors in the Queensridge community have fought those efforts, worried about high density and diminishing property values. The contention has ensnared the city of Las Vegas, which has been accused by the developer in courts of delaying applications, taking private property and bias. The dispute has cost city taxpayers nearly $1 million so far, and another $1 million has been allotted to fight several lawsuits. Now the city plans to file a legal brief in a Nevada Supreme Court case, agreeing with the developer that a judge’s ruling to invalidate a condominium project on the golf course was flawed. The move is conditioned on EHB Cos. coming to the negotiating table as the city seeks a resolution to ongoing litigation. City Attorney Brad Jerbic says the company has agreed. He insists neighbors will be involved in talks. But Frank Schreck, a gaming attorney, and Queensridge resident worries that revived conversation will exclude neighbors and lead to a backroom deal between the city and the developer.
