New development on east side of city to be built in phases Waxahachie Daily Light Two development projects took up most of the time of the Waxahachie Planning and Zoning Commission during Tuesday night’s meeting. A massive 2,973-lot plat of Saddlebrook Estates covering almost two square miles on the east side of Waxahachie along U.S. Highway 287 was approved by the commission. The plat derives from a zoning change to a planned development that dates all the way back to 2005. Senior planner Chris Webb said although the plat of the entire subdivision was being approved, the new neighborhood will be built in phases. Webb said any specifications for residential building materials in the PD have been voided by a state law passed in 2019 that prevents cities from mandating them.
