Stormwater Best Management Practices
2018 BMP Cost Share Reimbursement Program

What is stormwater?

Stormwater runoff is the water generated when rain, snow melt, and surface drainage flows over roof tops, land, parking lots, streets, sidewalks or driveways and does not percolate into the ground.

Where does stormwater go?

Stormwater runoff picks up sediment, contaminants, litter, nutrients, and other pollutants which then discharge untreated water into our waterways. Unmanaged stormwater could adversely affect these waterways by causing water pollution, stream bank erosion, and even flooding.

What can I do?

Constructing Best Management Practices (BMP's) to capture rain water where it lands and infiltrating or slowing down the stormwater will allow pollutants and sediment to settle out before they have a chance to discharge directly into waterways. BMP's are treatment facilities or measures, including rain barrels, rain gardens, bio-swales, stream buffers, native vegetation filter strips, stream bank stabilization and silt fence which reduce pollutant runoff. BMP's will help improve the water quality of our streams, creeks, and ponds, which ultimately improve water quality downstream in the Blue River, and Brush Creek.

Leawood's Cost Share Reimbursement Program

The City of Leawood and the Johnson County Stormwater Management Program have budgeted $5,000 for a BMP cost share reimbursement program. This program is an innovative approach to controlling stormwater quality impacts caused by stormwater runoff. The goal of this program is to encourage individual landowners and businesses to construct BMP's on their property to improve water quality. The program is intended to help cover the cost of materials, equipment rentals, and/or contractor labor to install such facilities. The City of Leawood and the Johnson County Stormwater Management Program will provide a 50% match on BMP's, up to $1,000 for rain gardens or native planting bio-swales/stream buffers, a 50% match on rain barrels, up to $75 and a 50% match on native trees up to $150. Funding is available to applicants on a first come, first serve basis and is subject to the approval of the Public Works Department. Funding will not be allowed for BMPs that are required for residential or commercial projects/developments.

Program Applicants Conditions:
