runoff control

Runoff control involves managing the flow of rainwater and melted snow so it doesn't cause problems like flooding, erosion, or water pollution. This is done by designing landscapes, infrastructure, and practices—such as rain gardens, detention ponds, and green roofs—that absorb, slow down, or redirect water. Proper runoff control helps protect ecosystems, maintain water quality, and reduce damage to properties by preventing excessive water from overwhelming drainage systems during heavy storms.
