Stormwater Best Management Practices

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, bioswales, 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 improvement water quality downstream in the Marais Des Cygnes River, Blue River, and the Kansas River.

Olathe’s Cost Share Reimbursement ProgramThe City of Olathe Dept. of Public Works, Stormwater Management Section is offering a Stormwater 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 Olathe Dept. of Public Works, Stormwater Management Section will provide a 50% match on BMP’s, up to $1,000 for rain gardens, bioswales, stream buffers, or native plantings, and a 50% match on rain barrels, up to $75 each.  Limit 2 rain barrels per application.  Funding is available to applicants on a first come, first serve basis and is subject to the approval of the Dept. of Public Works, Stormwater Management Section.  Funding will not be allowed for BMPs that are required for new development.
