Stormwater Management
Managing Stormwater in Our Community
Stormwater can pose a risk to our water resources. Pollutants in stormwater can impact lakes, streams, and rivers. Our community has adopted programs to control stormwater pollution.
The traditional approach to stormwater management focused on flood control. Today, Coralville manages both water quality and quantity by using practices that infiltrate more rainfall and reduce the volume of stormwater runoff.
Stormwater runoff is rainfall or snowmelt that runs off impervious surfaces like roads, buildings, and compacted soils. Stormwater runoff is collected and conveyed through storm sewers directly into streams, rivers, and lakes without being treated.
Pollutants accumulate on impervious surfaces between rainfall events. Frequent, small rains wash pollutants into streams, rivers, and lakes. These pollutants negatively impact water quality.
As communities grow, impervious areas increase. Greater impervious surfaces cause the volume and rate of stormwater runoff to increase. This can result in flooding, stream channel degradation, and increased water pollution in our surface waters.

About Stormwater

What Is Stormwater Runoff?
Stormwater runoff is rainfall or snowmelt that runs off impervious surfaces like roads, buildings, and compacted soils. Stormwater runoff is collected and conveyed through storm sewers directly into streams, rivers, and lakes without being treated.
The Problem
Pollutants accumulate on impervious surfaces between rainfall events. Frequent, small rains wash pollutants into streams, rivers, and lakes. These pollutants negatively impact water quality.
As communities grow, impervious areas increase. Greater impervious surfaces cause the volume and rate of stormwater runoff to increase. This can result in flooding, stream channel degradation, and increased water pollution in our surface waters.

Pave Drain InstallationThis video shows a new porous paver technology called Pave Drain soaking up water. Notice how the water runs off the concrete, but doesn’t make it past the first porous paver.
