Stormwater Management

Why is Stormwater Quality Important?

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. 
This program was developed to meet the requirements of the Texas Commission on Environmental Quality Phase II Municipal Separate Storm Sewers System Permit.

The City of Southlake has developed the following programs: 

  • Public education and involvement in stormwater quality,
  • Identification and disposal of pollutants in our creeks and streams,
  • Plan review, inspection, and enforcement for construction site runoff control,
  • Plan review, inspection, and enforcement for maintaining stormwater structures at sites that have already been developed, and;
  • Training and procedures for City staff to ensure our operations are environmentally-friendly
