TRWD owns and operates the Fort Worth Floodway where the river flows through the central part of the city. The District and the City of Fort Worth have long been partners in the MS4 permit that regulates stormwater discharges to the river. The goal of the permit is to implement practices within the city that will control and reduce the amount of pollutants to the river system. The pollutants of concern include sediment, nutrients, bacteria, and trash/floatables. The District has developed construction standards for all projects that occur in the floodway that are aimed at minimizing sediment loss during construction as well as establishing post-construction standards that will reduce erosion potential. In addition, all new outfalls to the river must include water quality measures to reduce floatables, sediment, and oils.
