 One of the earliest such developments was Quail Valley in Missouri City, whose golf course hosted the Houston Open during the 1973 and 1974 seasons of the PGA Tour.Another was First Colony in Sugar Land, a 9,700-acre development commenced in the 1970s by Houston developer Gerald D. Hines that eventually became the southwest Greater Houston area's main retail hub, anchored by First Colony Mall and Sugar Land Town Square.Since the 1980s, new communities have continued to develop, with Greatwood, New Territory, and Sienna Plantation among the more recent notable developments.
