KC Water manages 630 miles of sewers and more than 53,000 stormwater inlets. We also operate 15 flood pump stations and maintain six stormwater detention basins. We clean 18,000 storm inlets and repairs and replaces 300 catch basins annually.

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. To see the levee-protected areas in the Kansas City region, visit the National Levee Database here.

Kansas City, Missouri is part of the Federal Emergency Management Agency’s (FEMA) Community Rating System (CRS), which can help residents prevent or reduce flood losses. Please click here to learn more.

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.
