Why is stormwater important?
Stormwater Management prevents physical damage to people, aquatic life and communities by preventing polluted run-off from negatively impacting waterways. The installation of impervious surfaces interrupts the natural hydrologic cycle, and causes less infiltration than was present before any development occurred. Therefore, the volume and rate of stormwater run-off greatly increases, which as a result contributes to flooding, stream channel instability, sediment, herbicides, pesticides, oils, and other pollutants getting into the storm sewer system.

Stormwater Management provides environmental benefits to local communities and reduces the amount of sediment, herbicides, pesticides, oils and debris that gets into the storm sewer system, culverts, and ditches.
