Stormwater runoff can cause flooding and pollution problems if not properly managed. All storm drains on campus drain directly into nearby waterways carrying anything on the ground, so only stormwater should enter and not trash, leaves, or cigarette butts. Proper best management practices (BMPs) such as drainage ditches and retention ponds need regular maintenance and inspection to prevent pollution from items like animal feces, oil leaks, fertilizer, and human waste from entering local waters.
