Stormwater management routes water through the City in a way that prevents flooding and protects water quality.
Water Quality Protection
To reduce pollution in urban streams, the Environmental Protection Agency (EPA) expanded the Clean Water Act requiring municipalities to remove pollutants and protect water quality stormwater systems.
Issued by the State of Kansas, the National Pollutant Discharge Elimination System (NPDES) Permit requires the City to follow minimum control measures:
- Manage construction sites through Erosion and Sediment Control
- Manage sites after construction with flood control and water quality best management practices.
- Detect and eliminate Illegal Dumping into the Stormwater System.
- Provide public education such as Aquafest - Third Grade School Program and “Earth News” in the Olathe Link Newsletter.
- Initiate public involvement such as Stormwater Cost Sharing and Adopt-A-Stream programs.
- Pollution prevention
The City of Olathe commissioned a study to examine flooding issues throughout the City that were identified as part of the FEMA floodplain map update.
Watershed Preferred Alternatives Study
Floodplain maps identify areas of existing and potential flood risk zones and provide resources to help property owners determine if flood insurance is required.
