Stormwater Cost Share

Overland Park’s stormwater cost share program encourages residents and business owners to incorporate stormwater management strategies on their properties. These tactics reduce stormwater runoff and improve water quality.

Overland Park budgets funds for a cost share program to offset the costs of stormwater management projects that capture, slow down, or soak up stormwater close to its source.

Eligible Projects

The city will help cover the costs of materials and contractor labor to install many stormwater treatment projects.

Rain and Pollinator Gardens

Planting native landscaping reduces the amount of surface runoff that flows into our waterways. It helps rain infiltrate into the ground slowly to recharge streams, lakes, and wetlands at a more natural pace.

Stormwater runoff that flows through native landscapes is filtered, and contaminants are removed by plants and soil, results in cleaner, safer water.

Overland Park will cover 50 percent of the cost or a rain or pollinator garden, up to $1,000.

Rain Barrels

Rain barrels are 55-gallon barrels that capture water that would otherwise go down storm sewers and diverts it to areas of your property where it’s needed. They can help cut down on your water bill and move water away from your house that might otherwise cause foundation or flooding issues.

Rain barrels can be incorporated into your landscaping by planting or screening around the barrel. They are subject to applicable laws, including, but not limited to, the city property maintenance codes.

Overland Park will cover 50 percent of the cost of a rain barrel, up to $75.

Native Tree Plantings

Planting native trees reduces the amount of rainfall that reaches the ground, and therefore the amount of stormwater runoff. Trees filter out pollutants and sediment, taking up water from the soil through their roots, resulting in cleaner, safer water.

Native Buffers and Swales

Overland Park will cover 50 percent of the cost of native buffers and swales, up to $1,000.

Riparian Plants

Riparian plants cover land along stream banks, absorbing water and energy during storms and reducing the impact of flooding.

Overland Park will cover 50 percent of the cost of riparian plants, up to $1,000.

Rain Cisterns

Overland Park will cover 50 percent of the cost of a rain cistern, up to $1,000.

Permeable Pavement

Alternative materials including pervious asphalt, pervious concrete, interlocking pavers, and plastic grid pavers, allow rain and snowmelt to seep through the surface down to underlying layers of soil and gravel.

Floating Wetlands

Floating wetlands are container gardens that float on the surface of water. Local marsh and wetland plants filter pollutants in the water.

Apply to Participate

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 granted for projects that are required to meet stormwater treatment requirements of the City’s building and construction code.
