Everyone in the community has a part in preventing pollutants from entering storm drain inlets where they live and work. The Stormwater Ordinance (PDF) requires certain activities to reduce pollutants. Here are ways you can reduce pollutants.
Apply the Recommended Rate of Fertilizer
Nitrogen and phosphorus, which are in fertilizer, are pollutants of concern in our area. High levels lead to excessive algae growth in downstream water supplies resulting in foul tasting water. So you can save money, use less water, and protect the water by applying Appropriate Rates (PDF) (or less) or consider organic fertilizers. Never use high nitrogen fertilizers like 34-0-0. You should avoid fertilizing immediately before a storm, which will wash it downstream.
Don't Use the Street For Yard Waste Disposal
If you sweep or use a leaf blower, direct the waste back into the grass or dispose of it properly. If you have a side chute mower, direct it away from street. Yard waste should be properly disposed. If you have a landscape company, ensure they are properly disposing of waste.
Limit the Use of Yard Chemicals
Use chemicals only as a last resort and consider natural alternatives. Pesticides kill beneficial insects that help your landscape. Consider planting native plants, which require less maintenance.
Keep Your Yard Clean
Dispose of trash and litter, which can be windblown or carried away by stormwater. Bag and dispose of your pet's waste in a garbage can.
Other Activities
Instead of washing your car in the driveway, take your car to a commercial washing facility where the water is recycled.
Repair your vehicle leaks as soon as possible. If you have a big leak which you can't repair, consider parking your vehicle at night over a drip pan.
Dispose of used oil, oil filters, antifreeze, chemicals, and other acceptable products at the Environmental Collection Center.
Store chemicals, oils, and automotive parts in an area protected from the rain.
