What is a structure designed to collect runoff from small paved areas called?

The structure designed to collect runoff from small paved areas is referred to as an area drain. Area drains are specifically engineered to capture surface water runoff, directing it away from paved surfaces and preventing ponding or flooding. They typically consist of a catch basin and a drainage system that allows for the effective management of stormwater.

This is particularly important in urban environments where impervious surfaces can lead to increased runoff and water quality issues. By using area drains, excess water can be funneled into storm drains or other drainage systems, promoting proper drainage and reducing the risk of erosion or water damage.

Bioretention, on the other hand, is a green infrastructure solution aimed at treating stormwater through soil and vegetation but is not specifically designed for collecting runoff from paved areas. A base course refers to the layer of material used beneath a paved surface to provide structural support and is not a drainage structure. Finally, a bench may refer to a landscaped or seating platform but does not serve the purpose of collecting runoff. Thus, area drains are uniquely suited to the task of managing water from small paved surfaces.
