Curb cuts guide parking-lot runoff to the swales. These shallow grassy depressions are graded so that water flows slowly and does not pond. Pollutants adhere to soil and grasses and degrade, while water soaks into soil. Raised drains channel high flows to storm drains, preventing overflows and flooding.
