Rain runoff should drain into the soil first and then slowly into a water body. Runoff that goes directly into a water body carries leaves, fertilizers, and grass clippings. Watering the driveway won't make it grow. Save the hose for gardening, not sweeping. Use biodegradable detergents with little or no phosphate.
Storm drains are only for rainwater.
Drop off used motor oil at gas stations or garages that recycle. Motor oil is extremely toxic. Never pour used motor oil, leaves, lawn clippings or any other waste material into storm drains. Not all plants are bad. Vegetation along stormwater ponds, including weeds, helps absorb nutrients and pollutants that might drain into the Bay.
