Water, Wastewater & Stormwater Master Plan

Welcome to the Water, Wastewater & Stormwater Master Plan webpage of the Southlake 2030 Comprehensive Plan. The City of Southlake engaged Neel-Schaffer/Cheatham & Associates to develop the Water, Wastewater & Stormwater Master Plan update. Neel-Schaeffer/Cheatham & Associates utilized existing documents such as previous plans, system maps and construction documents as a basis for the plan update. Existing population and growth data from the North Central Texas Council of Governments (NCTCOG) were used, along with data from engineering studies, reports and designs performed for the City.
