Stormwater ponds 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:
- 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
- Also known as a detention pond, always has water in it
- This allows the area to be enhanced aesthetically. There is a wet pond in Pinnacle Ridge and it includes a fountain, paved walkways, benches, vegetation, etc.
- Primary function is to remove sediments and trap floating scum and debris
- By utilizing existing wetlands into our storm system, we reduce our impact to the natural environment.
