What type of storm water infrastructure is characterized by a grass-covered slope?

• A. Trench drain
• B. Culvert
• C. Swale
• D. Depression

Answer: (C)

The type of storm water infrastructure characterized by a grass-covered slope is known as a swale. Swales are designed as shallow, vegetated channels that facilitate the management of stormwater runoff while promoting infiltration into the soil. Being grass-covered, swales are effective in slowing down water flow, allowing sediments to settle, and providing a habitat for various plants and wildlife. Their design enhances both functional and aesthetic values in landscape architecture, often integrated into urban planning to manage water quality and mitigate flooding. They are typically used in both residential and commercial settings to direct water away from surfaces while reducing the potential for erosion. Other types of storm water infrastructure, such as trench drains and culverts, serve different functions. Trench drains are typically more structured and often consist of a channel that captures surface water without a natural vegetated slope, while culverts are usually used to convey water under roads or pathways through cylindrical pipes, lacking the intended landscape function of a grass-covered slope. Lastly, a depression might function as a basin for water collection but does not have the defined grassy slope that characterizes a swale. Thus, among the choices provided, the swale stands out distinctly for its vegetative features and its role in sustainable stormwater management.
