What are stormwater ponds?

They are areas which temporarily collects stormwater runoff and releases it at a controlled rate. The ponds improve the quality of the runoff by allowing the suspended solids to settle.

There are three basic pond types:

Dry pond

  • Also known as a retention pond, typically they are dry
  • There is a dry pond on the east side of the Community Knowledge Campus beside the running track. This type of pond allows the area to be utilized as a soccer field during dry periods.
  • Primarily used for quantity control
  • Not normally effective in removing sediments or other contaminants
