PHOENIX, AZ. – After a deliberative process, the Wild Horse Pass Development Authority (WHPDA) announced the selection of Scottsdale-based legacy developer Sunbelt Holdings to lead the development efforts for the property’s 3,300-acre project known as Wild Horse Pass. Located at the southwest corner of I-10 and the new Loop 202 freeway, new commercial development will provide new revenue streams to the Gila River Indian Community (GRIC) by responding to current market demand.

The newly envisioned Wild Horse Pass master plan, developed by a project team consisting of CallisonRTKL, Kimley Horn, and Elliott D. Pollack & Company, was recently approved by the Gila River Indian Community. The site is planned for a large-scale sports and entertainment district including additional hotels, a wellness center, an event center, an outdoor amphitheater music entertainment venue, sports facilities, outdoor recreation and parks, restaurants, retail, and an office park.
