Stormwater Cost Share Program

How it works

Lenexa’s Stormwater Cost Share Program helps residents pay for projects that treat stormwater runoff and reduce stormwater pollution. The city says the program is funded through a $15,000 grant from the Johnson County Stormwater Management Program, and Lenexa contributes an additional $7,500.

The program reimburses a portion of eligible costs after installation. The page says funding is awarded on a first-come, first-served basis.

What the money covers

The city lists these eligible projects for reimbursement:

• Rain gardens
• Rain barrels and cisterns
• Native plantings
• Permeable pavers

The page explains that rain barrels and cisterns provide water for outdoor use and help divert roof runoff away from storm drains. It also says permeable pavers can be used for walkways, patios, and driveways, where they let water seep into a crushed aggregate reservoir and soak into the ground.

Amounts and matching

Eligible residents can receive 75% reimbursement for eligible expenses.

The page gives these limits:

• Maximum reimbursement of $110 for rain barrels
• Maximum reimbursement of $225 per native tree
• Total project maximum of $1,500

How to apply

The page includes an application section titled “Apply for reimbursement.” It says the city offers application options through the program page, and that the next application period opens in March 2027.

Timing and deadlines

The page says all of the money has been allocated for the current year. It does not list a specific closing date, but it does say the next application period opens March 2027.

Notes for homeowners

The page says residents can install rain gardens, native vegetation, and rain barrels on their property and receive help through the program. It also notes that Lenexa occasionally hosts rain barrel building classes through Lenexa Parks & Recreation.
