Why do we manage stormwater?
Under the Clean Water Act (CWA), the federal government began programs to reduce pollution from entering our streams, rivers, and lakes. Stormwater, in the form of rainfall or snowmelt, shares responsibility for carrying pollution to these waterways, so its management has been delegated to local municipalities as part of the MS4 permit program. Some of the pollutants that need to be managed include:
• Sediment or soil
• Road salt
• Fertilizers (specifically nitrogen and phosphorus)
• Herbicides and pesticides
• Excessive heat
• Trash (plastic bottles, food wrappers, cigarette butts, etc.)
While none of these pollutants should enter local streams, rivers, or lakes, each waterway can have its own list of pollutants that are of special interest within that waterway. These lists are known as Total Maximum Daily Loads (TMDLs), or the total amount of identified pollutants that affect a waterway, and are monitored and updated by the Ohio EPA.
How can we limit the pollution that enters the Plum Creek?
There are features known as Stormwater Control Measures (SCMs) or Best Management Practices (BMPs) that can be installed on individual properties and throughout cities to improve stormwater management. Some SCMs can easily be used around residential homes. Other SCMs work better in larger areas.

A type of bioretention area designed as a shallow depression in the ground to store runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas. Rain gardens often incorporate native plants.

2) Master Rain Gardener Coursepack
A container used to collect and store stormwater runoff. Typically house or garage gutters are diverted to fill a 55 gallon barrel, which is then used to water lawns or nearby gardens during a dry period. Cisterns are similar to rain barrels, and hold larger quantities of water.

Riparian Setback/Buffer Strips
A depressed area designed to store and filter runoff from impervious areas like parking lots and roofs. They can include specific soil media and plants to filter and/or treat stormwater, as well as drain pipes.
