El Niño Ready • Runoff Pathways
Rain does not disappear when it hits pavement.
On a paved site, water moves. The useful question is not just “Is there a storm drain?” It is “What does the water pass before it gets there?”
Start at the waste area and walk downhill.
Look at the actual site. If rain lands on or near the enclosure, where will the water go? Across the pad? Along a curb? Through a parking aisle? Into a gutter? Toward an inlet? This simple walk-through often reveals loose material, staining, low spots, damaged containers, or housekeeping issues that are easy to miss when the weather is dry.
A closed lid is a simple pollution-prevention practice.
Keeping outdoor waste containers closed where practical helps limit direct rain contact with waste and helps contain lightweight material. It is not the only control a site may need, but it is one of the easiest habits to standardize.
U.S. EPA stormwater guidance emphasizes good housekeeping and preventing pollutants from contacting stormwater. Local permit, waste, and property requirements vary.
