As stormwater runoff travels over the land, it picks up all kinds of chemicals, waste, and trash that are not naturally found in our waterways. Stormwater runoff enters the storm drain system through inlets and carries this untreated water straight to creeks, lakes, and rivers. Some chemicals and other pollutants in the stormwater can be toxic, even at small levels, endangering plants and animals that depend on the water to survive.
Keeping our creeks and streams clean not only benefits the Southlake community but also benefits the entire network of water bodies and land that make up our watershed, including Grapevine Lake and Big Bear Creek.
The Stormwater Management Plan is a City-wide program that has adopted best management practices to prevent pollution of our creeks and streams.
