Flooding and Stormwater Management
West Branch Chisholm Creek Watershed Study
The Sedgwick County Stormwater Management Advisory Board completed a study in April of 2016 of the 18 square mile West Branch Chisholm Creek watershed located in Valley Center, Wichita, Park City, Kechi and rural Sedgwick County. The final report identifies potential improvements to address areas of flooding, channel erosion and sedimentation throughout the watershed. Please contact Scott Lindebak, PE with any questions regarding this study at email@example.com or (316) 660-1754.
Spring Creek Basin Watershed Study
The Sedgwick County Stormwater Management Advisory Board completed a study in January of 2014 of the 32 square mile Spring Creek watershed located in Derby, Wichita, and rural Sedgwick County. The final report identifies potential improvements to address areas of flooding, channel erosion and sedimentation throughout the watershed. Please contact Scott Lindebak, PE with any questions regarding this study at firstname.lastname@example.org or (316) 660-1754.
Why should we manage stormwater?
Stormwater that is not absorbed into the ground has to go somewhere - preferably somewhere that doesn't cause flooding or poor water quality.
Stormwater management is a cross-jurisdictional collaboration that weighs historical information, current conditions, and future plans and development to help keep stormwater from creating flooding and water quality problems.
Flooding Affects Everyone
During Sedgwick County's “rainy season,” which is usually in the spring, neighborhoods throughout the county can experience flooding. And, the fact that your home has never flooded before is not a guarantee that it won’t happen in the future. The frequent addition of roads, buildings and parking lots make our lives easier, but also make floods more likely and more severe. So, even if you are not at risk of flooding today, tomorrow may be a different story.

Stormwater Affects Water Quality
Stormwater not absorbed by the ground, or stormwater runoff, can be damaging to the environment and contributes to flooding. In fact, it's the number 1 water pollution problem in the United States.
This runoff carries debris, chemicals and other pollutants into storm sewers or directly into the creeks, rivers, and lakes we use for fishing, swimming, and drinking water. Managing this runoff, or stormwater management, is necessary to protect our water quality, but it's also expensive.
Choices Today Affect Water Tomorrow
The choices we make affect our ability to manage stormwater. Everyone can play an important role in reducing stormwater runoff and the problems and costs that accompany it. The solutions start with paying attention to stormwater at home, at work and in our communities.
Sedgwick County is currently allowed to discharge stormwater to waters of the United States through its Municipal Separate Storm Sewer System (MS4 - inlets and pipes, as well as open ditches, which discharge to waters of the U.S. and are owned and maintained by Sedgwick County). This is possible due to our Kansas Water Pollution Control General MS4 Permit and Authorization to Discharge under the National Pollutant Discharge Elimination System (NPDES).
Essentially, the NPDES is a permit program managed by the Environmental Protection Agency.
