Stormwater Pond Design
A stormwater retention pond is an artificial lake which includes a permanent pool of water. Typically, sod is placed around the perimeter. However, sod is not efficient vegetation for water filtration. Rather, it is recommended that stormwater retention area design incorporate native wetland plants along a gradual slope. In this design (considered aquascaping), stormwater retention areas can be incorporated into the design of a development or transportation corridor as attractive public use areas. These areas can provide suitable wildlife habitats. Some areas may even incorporate fishing activities. Below are some suggestions for beneficial stormwater retention area design that can be incorporated in development plans. The Florida Department of Transportation has certain design and liability constraints which may prevent the inclusion of some of these suggested design elements.
Suggested Design Elements:
- Choose a diversity of native wetland plants.
- Consider a gradual graded-slope configuration.
- Control exotic vegetation through mechanical and chemical treatments.
- Ponds should be constructed away from emergent or other wetlands so as not to cause alteration of hydrology.
- Ponds should be sited in previously disturbed areas to avoid habitat loss.
- Incorporate park benches and nature trails on non-DOT retention areas.
- Incorporate educational kiosks and signs to educate people about wildlife usage and prohibit dumping or feeding wildlife (only observation).
- Incorporate wildlife observation decks on non-DOT retention areas.
- Reduce or eliminate fencing of some stormwater features when legally feasible on non-DOT retention areas.
- Place ponds away from either side of a wildlife crossing.
