KC Water also manages 13.7 miles of levees and floodwalls along the Missouri River or its tributaries in the area, with an additional 2.2 miles under construction. Utility and construction work within the critical zone of levees requires additional review by the KC Water Stormwater Engineering Division.

KC Water Updates Stormwater Management Plan
KC Water has drafted an update to the Stormwater Management Plan in effect since 2019. The proposed draft plan describes strategies and practices the City implements to manage the discharge of pollutants from the Municipal Separate Storm Sewer System and is required by the Municipal Separate Storm Sewer System Discharge Permit issued by the Missouri Department of Natural Resources (MoDNR) in September 2018.
KC Water received comments through July 1, 2022 on the proposed plan, which is posted below and is undergoing final review. The current 2019 Stormwater Management Plan also is posted below. For further information, contact Jing Tao, Stormwater Engineering Division, at 816-513-0371 or Jing.Tao@kcmo.org.
Property Owners and Tenants Information
The Stormwater Fee is calculated as $0.50 per 500 square feet of impervious area. The average Stormwater Fee is $2 to $3 per month.
The Stormwater Fee covers the cost of stormwater planning and maintenance of the stormwater system. It cannot be used to expand the system (new construction).
Stormwater is a natural resource and each property owner can collect the stormwater that falls on their property. The City has a storm drainage collection system. The City also has regulations concerning the impacts that individuals can have on the storm drainage system including how much can be discharged and limitations on development in streams that could impact adjacent property owners.
The City considers there to be four primary ways that a property could flood. A property can be flooded by one or more of these flood types. The majority of properties in Kansas City are at risk from at least one of these types of flooding.
||Water rising out of the creek and goes into your property.
|2. Hillside Drainage
||Water trying to get to the creek and goes through your property.
||Water seeps through the ground, hits bedrock, and flows
underground to your basement.
|4. Sewer Backup
||Water enters the wastewater lines, either through seepage or
through the combined sewer, and backs up into your house.
Visit the City’s parcel viewer to see your risk from Type 1 – Floodplain flooding. If your property is not within the identified floodplains, your risk is unidentified.
You can report flooding on your property through the City’s 311 system.
The Federal Emergency Management Agency (FEMA) and the Missouri State Emergency Management Agency (SEMA) provide resources to help understand and manage flood risk.
Look at the City’s Parcel Viewer to understand your risk from river flooding. Look around your property. Does the ground slope towards any of your structures? Is there land near you that is higher than your property? If so, you may be at risk. Review the Quick Guide from the Missouri State Emergency Management Agency for detailed information about understanding river flooding.

Anyone can purchase flood insurance. Visit FEMA’s website for more information.
