Properly Clean Parking Lots
Most parking lots are impermeable surfaces and rain will wash all litter, debris, sediment, fertilizer and chemicals from automobiles into the storm drains. This is nonpoint source pollution and impermeable surfaces like parking lots accelerate storm water runoff which travels into our streams, the bay and the Gulf. These pollutants can harm marine creatures and wildlife, kill native vegetation and strengthen invasives, contaminate the water, and make recreational areas unsafe and unpleasant.
Major source of Nonpoint Source Pollution
As litter, debris, sediment, fertilizer, and chemicals wash off parking lots and into storm drains, pollution quickly drains into area streams, rivers, and bays. Most storm drains have no method of filtering out this pollution, and once itís in the water, it becomes increasingly difficult to remove.
Littering Increases with Lack of Trash Receptacles
Existing litter and lack of opportunity for proper disposal invites littering. Most littering occurs when there is no receptacle within 10 feet or less or if the place is already littered.
Lack of Ashtrays
Cigarette butts remain the largest category of litter picked up nation-wide. This is evident to anyone who has cleaned a parking lot. Providing ashtrays throughout the parking lot is a way of cutting down on this type of litter (Keep America Beautiful, 2009)
Things You Can Do
Pick Trash Up
Assign a staff member or hire a parking lot cleaning company to pick up trash and debris regularly so that your parking lot appears clean and so that rain does not wash pollution into storm drains that empty into our streams and bayous.
Provide More Trash Receptacles
Littering rates are shown to decrease as the convenience of using a proper receptacle increases. Receptacles are most effective when they are within 10 feet of a person who needs it.Safco Canmeleo REcessed Waste Receptacle with Ash Urn (Amazon)
Empty Trash Receptacles When Full
Ensure trash receptacles are routinely checked and emptied to prevent overfilling and spillage.
