STORMWATER MANAGEMENT - Contact Stormwater Staff
Stormwater runoff occurs when precipitation from rain or snowmelt flows over the land surface.  The City of Olathe’s stormwater system includes thousands of street curb inlets, boxes, miles of pipes, streams, lakes, and ponds.   The Department of Public Works’ Stormwater Section implements flood control projects and water quality protection measures that protect the natural and developed environment, while providing public education and involvement opportunities.
In 1990, the City of Olathe established a stormwater utility and began collecting fees to fund stormwater system maintenance and enhancement. Over the years, stormwater activities have been conducted by several City departments and divisions.  In 2011, the Stormwater Section was formed under the Infrastructure Management Division of Public Works.

Flood Control - The addition of roads, driveways, parking lots, rooftops and other impervious surfaces that prevent water from soaking into the ground greatly increases the runoff volume created during storms. This runoff is swiftly carried to local streams, lakes, and rivers and can cause flooding and streambank erosion.  The Stormwater Section implements a wide variety of flood control projects and maintains existing infrastructure to prevent street and structure flooding.

Flash Flooding Tips to Remember

Water Quality Protection - Stormwater runoff also picks up and carries with it many different pollutants such as sediment, nitrogen, phosphorus, bacteria, oil and grease, trash, pesticides and metals.  To reduce pollution impacts on urban streams, EPA expanded the Clean Water Act in 1987 to require municipalities to obtain National Pollution Discharge Elimination System (NPDES) permits for stormwater discharges. The City of Olathe is required to implement six minimum control measures: public education and outreach; public participation and involvement; illicit discharge detection and elimination; construction site runoff control; post construction runoff control; and, pollution prevention for municipal operations. As a result, the City of Olathe adopted Title 17 Stormwater Management regulations that minimize the impacts of urban development. The Stormwater Section is responsible for meeting NPDES Stormwater requirements and providing code enforcement for Title 17 regulations.
