About Stormwater
What Is Stormwater Runoff?
Stormwater runoff is rainfall or snowmelt that runs off impervious (hard) surfaces such as roads, buildings, and compacted soils. This runoff is collected and conveyed through stormwater systems (usually pipes), or flows as surface runoff directly into our streams, rivers and lakes without being
treated.
Dangers and Risks
Stormwater can pose a risk to our water resources. Pollutants (e.g., sediment, nitrates and bacteria) accumulate on impervious surfaces between rainfalls. Frequent, small rains wash pollutants into streams, rivers and lakes. These pollutants negatively impact water quality. Too much
stormwater can also adversely affect infrastructure, weakening bridges and damaging environmentally sensitive areas.
Solutions
Johnson County requires the management of water quality and quantity through practices that allow more rainfall to infiltrate into the ground or be stored for other purposes (e.g., rainbarrel).

A bio-retention cell (above) helps remove pollutants from stormwater that runs off a nearby parking lot. This stormwater feature is located just south of a parking lot for the Johnson County Administration Building.
