Contain the Rain Program opens this spring to incentivize stormwater management

April showers bring May flowers, and they also bring stormwater runoff. This spring, the Contain the Rain Program is back open for cities across Johnson County, supporting stormwater management projects that help combat stormwater runoff. 

The program, open for its 13th year, reimburses residents up to 50% of the cost of stormwater management projects like rain barrels and rain gardens. These projects counteract stormwater runoff by collecting rainwater, which you can use to water your lawn or garden. 

How to Apply for Your City’s Program

Residents in the following cities, as well as unincorporated Johnson County, are eligible for reimbursement: 

Please review your city’s criteria for reimbursement to apply for funding. For De Soto, Fairway, Lake Quivira, Mission Woods, Roeland Park, Westwood, and Westwood Hills, please visit for information and to apply. 

Eligible Stormwater Management Projects

During rainstorms, stormwater runoff can collect pollutants, such as fertilizers, pesticides, household hazardous wastes and trash, and carry it into lakes and streams. That’s why stormwater management projects are vital to protecting the environment. 

The following projects are eligible through the Contain the Rain program: 

  • Rain barrels 
  • Rain gardens 
  • Cisterns 
  • Floating wetlands 
  • Impervious pavement 
  • Native plant swales 
  • Native trees

Projects like rain gardens not only benefit the environment by preventing pollution, but they also help support our local pollinator species, make our lawns more resilient and help reduce unnecessary water usage.
