What is Stormwater Management?
Stormwater management affects everyone in a community: residents, businesses and even the local government.
With traditional management, street flooding becomes common, resulting even from moderate rains, and streams erode and destroy both public and private property. These problems come from the use of concrete pipes to move stormwater away from where it falls as fast as possible with little concern of downstream effects.
This program focuses on management of stormwater at the source: holding rain and melting snow where it falls for longer. The result is to slow the movement of water, which reduces flash flooding and erosion downstream.
Grants & Cost-sharingApply: Best Management Practices matching grant
The City of North Liberty offers a cost-sharing program of up to $2,000 with the goal of improving the quality of stormwater runoff and reducing the pollutants entering the city’s storm sewer system and waterways through the use of best management practices. The program provides funding assistance for property owners who install improvements following best management practices related to stormwater quality in North Liberty.
Best management practices covered by our program include:
- Rain gardens
- Pervious paving and other infiltration practices
- Bank stabilization
- Soil quality restoration – check out our Your Best Lawn program.
and other generally accepted stormwater quality best management practices as approved by the city.
Approved practices must conform to the Iowa Stormwater Management Manual.
Funding is limited to one qualifying application per improvement that isn’t regular or required maintenance. For the grant, property owners must complete an application and submit a plan showing the details of the improvement. For questions about applying, contact Stormwater Coordinator Mike Wolfe.

Stormwater runoff is regulated at the Federal level by the Environmental Protection Agency. Stormwater regulations help ensure mitigation of pollutants and potential pollutants in stormwater. The public plays an active role in helping keep stormwater clean. The best way to protect our water sources through stormwater management is to limit what enters storm sewers and waterways. The public is warned against dumping anything but rainwater into storm sewers. Dumping hazardous materials into the storm drainage system is illegal.
The intent of the federal stormwater regulation is to improve water quality by reducing or eliminating contaminants in stormwater. Stormwater is defined as precipitation runoff, surface runoff and drainage, street runoff, and snow melt runoff.
Stormwater runoff from areas where industrial activities occur may contain toxics (for example, lead, zinc, etc.) and conventional pollutants such as oil and grease, fertilizers, sediment from construction sites, and other industrial site contaminants, when material management practices allow exposure to stormwater. In addition, illicit connections to storm sewers may also exist and introduce contaminants through storm sewer systems. Eventually these contaminants have the potential to effect additional downstream receiving waters. Contaminants introduced in stormwater runoff or into storm sewers may impact drinking water sources, waters protected for recreation, waters protected for aquatic life as well as other beneficial uses.
Regulation of stormwater in municipalities may require a National Pollutant Discharge Elimination System (NPDES) Permit, which the City holds and is issued by the Iowa Department of Natural Resources (IDNR). The IDNR is delegated by the US Environmental Protection Agency to oversee the permitting. A copy of the City of North Liberty’s NPDES permit for Municipal Separate Storm Sewer System (MS4) regulation can be viewed here.
Residents are encouraged to submit complaints to the City on stormwater issues, to help keep track of potential problems in the City. You can submit a complaint online or by calling (319) 626-5700.
