General Information


What is Storm Water?

Storm water results from precipitation or snowmelt, and is the largest contributor to water pollution. It runs off our streets, driveways, and roofs into our waterways without prior treatment. Although storm water is a natural process, it can cause many negative impacts when construction is taking place.

Negative Impacts of Storm Water:

The majority of storm water becomes runoff and picks up pollutants such as; oil, nutrients, sediment, metals, and bacteria as it is transported across impervious surfaces. Almost all of the pollutants that storm water picks up ends up in surface waters. Storm water also increases the amount of erosion that is taking place.  This can result in turbidity, an increase in flooding, and an increase in the amount of pollutants being transported to other bodies of water.

What is a Detention Basin?

A detention basin collects storm water, stores it temporarily, and then releases the water at a controlled rate.  This slows down the rate of runoff and improves the quality of water.  It also reduces the negative impacts of storm water. Many times there is wetland, vegetation within detention basins, and buffer strips to improve the water quality by filtering pollutants that are in storm water. If detention basins are not properly maintained, they will no longer work efficiently.

What you can do to Help Reduce the Impacts of Storm Water:

  • Have detention basins regularly inspected to guarantee that they are working properly.
  • Check catch basins for leaves, debris, or sediment build up. Over time, catch basins become filled with sediment and need to be cleaned out to improve water quality and water flow.
  • Develop a rain garden.
  • Minimize the use of fertilizer and pesticides.
  • Store fertilizers and pesticides in locked containers.
  • Never wash fertilizer spills down driveways. The runoff will go into the groundwater and pollute.
  • When dealing with a spill of liquid fertilizer apply kitty litter or sawdust, sweep it into a newspaper, and then dispose of it in the trash.
  • Keep the grass height about 2 1/2 to 3 inches.
  • Do not remove grass clippings. They provide a natural mulch for your lawn.
  • Use a broom rather than a hose when washing any hard surface.
  • Save existing mature trees. This reduces soil erosion.
  • Maintain buffer strips. Buffer strips prevent erosion, filters soil particles, provides temperature control, and reduces sediment and nutrient impacts from natural erosion.
  • Keep in mind that everything that is poured on the ground, streets, or driveways has the potential to be carried by storm water and transported to surface waters.

Waterfront Property Owners


Waterfront property owners have a great ability to protect water quality since they live on a riparian zone. A riparian zone is the interface between land and water.

Riparian Zone Functions

  • Maintaining stream flows
  • Cycling nutrients
  • Filtering chemicals and other pollutants from runoff
  • Trapping and redistributing sediments
  • Absorbing and detaining floodwaters
  • Maintaining fish and wildlife habitats
  • Supporting the food chain for a wide range of organisms

Take the Following Steps to Ensure Clean Water:

  1. Minimize Storm Water Runoff from Your Property
  2. Prevent Soil Erosion and Sedimentation
  3. Maintain a Healthy Lawn and Garden
  4. Plant and Maintain a Naturalized Shoreline or Stream Bank Buffer
  5. Properly Manage Home, Yard, and Animal Waste
  6. Properly Maintain Your Septic System
  7. Properly Maintain Your Boats and Other Recreational Activities
