“Stormwater” is a form of water that we all deal with regularly: rain, hail, snow and everything else that falls from the sky as precipitation. As soon as it hits the ground, it either gets absorbed, or it flows directly into our local rivers, lakes, and streams. Too much stormwater can cause problems, such as flooding, erosion, and pollutant transport. Stormwater controls can be installed in many places but the best place to manage stormwater is the spot on which it lands. 

The Stormwater Best Management Practices Rebate Program provides an incentive for private property owners to install stormwater best management practices on their property. These practices help enhance the water quality of stormwater runoff, decrease the amount of stormwater runoff that ends up in the storm drainage system, and/or repurpose the energy and nutrients of stormwater for healthier soils and landscaping. The City will reimburse property owners 50% of the total cost of their project, with a reimbursement limit of $2000, provided the project and property owner meets the requirements of the program, listed below.

For those living outside the City of Des Moines, follow Polk Soil and Water Conservation District's #RainCampaign for information about stormwater management programs available across the metro area. Additional information can also be found through the Iowa Stormwater Education Partnership.

Why Should I Apply For The Program?

• Every property is different, but every property can most likely benefit from the installation of a stormwater best management practice. There is almost always a project that will work for your property, no matter how big or small.
• You don’t have to install a large basin or a excavate your backyard in order to qualify for our program – even the installation of a rain barrel could make a difference!
• Some projects end up paying for themselves over time. For instance, a Soil Quality Restoration (SQR) dramatically limits your lawn’s need for nutrients, fertilizer, and water. Not only could you spend less on lawn maintenance, but you could also save on your water bill!

What Qualifying Work Is Best For My Yard?

Rain Barrels

Installing a rain barrel is a relatively inexpensive process. The rain barrel connects to the downspout of any gutter system and collects rain water. This harvested rain water may be used for watering yards, tending to gardens or other household needs. 

Rain Gardens

Rain gardens capture runoff from a variety of impervious surfaces in a depression or shallow bowl. Runoff captured by a rain garden is temporarily ponded, and is allowed to soak into the soil rather than running into storm drains. These features are suitable for yards and other small drainage areas where drain spouts can be redirected.  

Bioretention Cells

Bioretention cells have an engineered and constructed sub-grade to ensure adequate percolation and infiltration of captured runoff. These features are best placed near impervious services to reduce water pollution and stabilize stream flows. 

Permeable Pavers

Because roads, parking lots and driveways account for more than 60 percent of impervious surfaces in urban areas, permeable pavement systems can go a long way to reduce the amount of runoff entering the storm sewer system.

Soil Quality Restoration

Soil quality restoration involves reducing soil compaction. This practice will increase organic matter, promote infiltration and soil quality, while decreasing the need for watering and chemical treatment of lawns. 

Streambank Stabilization

Streambank stabilization is a process in which streambanks are reconstructed or armored to reduce streambank erosion and subsequent sediment flows.
