Clear Creek Tidal: Implementing TMDLs through Low Impact Development in League City

Low Impact Development (LID) features installed in League City to support the TMDL Implementation Plan for Clear Creek Tidal.


League City is southeast of the city of Houston, on the south shore of Clear Lake. It straddles the watersheds of Clear Creek and Dickinson Bayou, two important recreational water resources impaired by high bacteria levels. A TMDL implementation plan for bacteria for the Clear Creek watershed and many other Houston-area watersheds was approved in 2013.

Project Description

League City installed LID features in a demonstration park. The features include swales, rain gardens, pervious pavement, rainwater harvesting, green roof, "WaterSmart Landscaping," and vegetated buffers. The features' performance in improving water quality was monitored. The results are contained in the Project Final Report and are being offered for use in developing appropriate storm water ordinances.
