A wet pond is a permanent pool where stormwater is captured and regulated by an elevated outlet structure. Native vegetation should be used to provide a permanent buffer around the pool. Water from the pond should be used for irrigation or some other beneficial use.
Wet ponds are used to accommodate runoff and provide stability from larger design storms. They can also be used when wildlife habitats, recreational benefits, or water supply for irrigation or fire protection need to be enhanced. Wet ponds may look similar to constructed wetlands, but their plantings, soil, and subsurface systems are very different.
- Use of wet ponds under Table 5-2 requires a 10-foot-wide area of native vegetation along at least 50% of the shoreline.
- Safety ledges are required around wet ponds deeper than 3 feet.
Maintenance: Regular maintenance activities include inspections, sediment/ debris removal, and landscape services for vegetated areas. The forebay must be cleaned once 6 inches of sediment have accumulated.
