Yes, there are several exterior features used for managing stormwater runoff, including bioswales and retention ponds. These features are designed to collect, store, and filter stormwater, preventing it from causing flooding and pollution.
Bioswales, also known as vegetated swales or biofilters, are landscape elements designed to slow and absorb stormwater runoff. They consist of gently sloped channels or depressions planted with vegetation, often native plants or grasses. As stormwater flows through a bioswale, the plants and soil help filter out pollutants and absorb excess water. Bioswales are commonly used in parking lots, roadways, and other open spaces.
Retention ponds, sometimes called detention ponds or stormwater ponds, are created to temporarily hold stormwater runoff, typically from urban areas. These ponds are designed to collect and store excess water during heavy rain events, which then slowly drains over time or is gradually released into streams or other bodies of water. Retention ponds are usually designed with a variety of vegetation, soil, and layers to promote filtration and treatment of the captured stormwater.
Other exterior features used for stormwater management include rain gardens, permeable pavements, green roofs, and infiltration trenches. Each of these features aims to capture, treat, and slow down stormwater runoff, reducing its impact on the surrounding environment.
