What is stormwater?

Stormwater is discharged into our waterways. Runoff picks up sediment, contaminants, litter, nutrients, and pollutants. Unmanaged stormwater can cause water pollution, stream bank erosion, and flooding.

What can I do?
Constructing Best Management Practices (BMPs) to capture water where it lands allows pollutants and sediment to settle before they have a chance to discharge directly into waterways. BMPs include the following:
  • rain barrels (can be purchased from local retail/home improvement stores or online)
  • rain gardens
  • bioswales
  • stream buffers
  • native vegetation filter strips
BMP’s help improve the water quality of our streams, creeks, ponds and the Des Moines River.

What is the City of Pleasant Hill doing about stormwater management?

In 2004, the City of Pleasant Hill became an “MS4 City” with a Municipal Separate Storm Sewer System permit issued by the Iowa Department of Natural Resources. This permit regulates the City’s requirements for managing stormwater. Click here to view MS4 permit.

What can I do to prevent water pollution?

There are a number of practices homeowners can use on their properties to limit their impact on stormwater runoff and quality. A detailed toolbox of techniques and practices, as well as a list of contractors trained to do the work is available on the Rainscaping Iowa website.

The following is a list of practices you can begin today to help become part of the solution to preventing water pollution:

Home Maintenance
  • Buy household products such as cleaners and furniture polish labeled "non toxic." Use small quantities and purchase only the amount you need. 
  • Properly use and store all toxic products, including cleaners, solvents and paints. Use up paint cleaners and other products or share leftovers with a neighbor. 
  • Take household hazardous materials and containers to a hazardous material collection center. 
  • Use kitty litter or other absorbent materials to clean spills. Depending on the substance, dispose absorbents in the trash can or at a hazardous materials collection center. 
  • Rinse water-based paint brushes in the sink. Filter and reuse paint thinner or brush cleaners. Dispose of used thinner, oil and latex paint at a hazardous materials collection center. 
  • Recycle reusable materials. Throw litter into trash cans and keep cans tightly covered to prevent foraging by animals. 
  • Control erosion during construction to prevent dirt and debris from entering storm drains. 
Lawn and Garden
  • Use pesticides, herbicides and fertilizers in accordance with label instructions. Do not apply before rain, or during strong winds, and dispose leftovers at a hazardous materials collection center. 
  • Use a broom rather than a hose to clean up garden clippings. Put leaves and clippings in a trash can or a compost pile. 
  • Divert rain spouts and garden hoses from paved surfaces onto grass to allow water to filter through the soil. Water only your lawn and garden. 
  • Pick up animal waste and dispose in the trash can. 
Do you have a stormwater concern? For example, is there mud in the street, or have you witnessed a spill or dumping in the storm sewer? Do you have a question about a program or an issue?
