Stormwater Treatment Facility Cost-Share Reimbursement Program

The City of Overland Park has partnered with the Johnson County Stormwater Management Program to provide $10,000 for a stormwater treatment facility (STF) cost-share program. This program is an innovative approach to controlling stormwater quality impacts caused by stormwater runoff.

Stormwater runoff is the water that is generated when rain, snow melt, and surface drainage flows over land or impervious surfaces and does not percolate into the ground. Impervious surfaces are defined as hard surfaces where water is unable to soak or infiltrate into the ground, such as streets, parking lots, sidewalks, and roof tops.

As stormwater runoff flows over land and impervious surfaces, it picks up sediment, contaminants, litter, nutrients, and other pollutants which then discharge into the waterways within Overland Park untreated. Unmanaged stormwater could adversely affect these waterways by causing water pollution, stream bank erosion, and even flooding.

How you can help

By capturing rain water where it lands, and infiltrating or slowing the stormwater down through STFs, the pollutants and sediment have a chance to settle out rather than create an adverse effect on Overland Park's waterways. These facilities can help improve the water quality of our streams, creeks, and ponds, and can ultimately help improve the water quality downstream in the Kansas River.

The goal of this cost-share program is to encourage individual homeowners and businesses to incorporate STFs on their property to aid in the improvement of water quality. The program is intended to help cover the cost of materials and/or contractor labor to install such facilities. The City of Overland Park will provide a 50% match on STFs, up to $1,000 for rain gardens or native planting swales/buffers, and a 50% match on rain barrels, up to $75.

Note: Lily Retainers purchased from Johnson County Stormwater Management Program are not refundable under the cost-share program because they are already sold at a reduced cost to residents.

Funding is available to applicants on a first come, first serve basis, and applications will be considered in the order they are received. Funding will not be allowed for STFs that are required to meet Chapter 16.210 of the OPMC.
