Stormwater Pollution Prevention

La Verne's storm drain system was designed to prevent flooding by transporting excess rainwater from city streets. Since the storm drain system contains no filter, untreated storm water is released into various water bodies. Storm water pollution occurs when untreated contaminated water (urban runoff) drains from city streets into the rivers and oceans.

Did you know that the largest source of storm water pollution is residents? Through the conduct of daily activities, the general public releases various pollutants into the storm drain. Urban runoff is the largest source of unregulated pollution to the waterways and coastal areas of the United States. The most common pollutants released into storm drains are:

  • Fuel and motor oil leaking from cars
  • Household cleaning products
  • Improperly disposed paint and paint thinners
  • Paper, cups, and other litter
  • Yard waste and fertilizers
  • Animal waste left from household pets

These pollutants are transported into the city's storm drain system by various sources such as rain, hoses and sprinklers, which drain from streets, parking lots, and lawns to enter various catch basins, that leads to rivers and oceans. Storm water pollution destroys the natural beauty of our beaches and waterways in addition to harming both marine wildlife and plant life. It can also lead to unsafe swimming conditions in our beaches and lakes. To prevent storm water pollution follow these simple tips:

  • Never pour household hazardous waste materials down the drain, onto sidewalks or into catch basins. Take these materials to a hazardous waste materials collection center or round-up event. For the next Household Hazardous Waste Round-up click on the following link
  • Use pesticides, herbicides, and fertilizers according to the label instructions. Remember not to apply them before rain and avoid over watering your plants or lawn.
  • When walking your pets, remember to pick up your animal's waste and dispose of it in a trashcan.
  • Never put motor oil in the trash or pour it on the ground or down a storm drain. For more information on used motor oil or filter recycling click on the following link Used Oil & Filter Recycling.
  • If you're using latex-water based paints, you can wash your paint brushes directly in your kitchen or bathroom sink. Don't rinse your brushes into the street. If you use oil-based paints, clean them by rinsing brushes with solvent in a container. Take the unused liquid and residue to a HHW collection event.

The City tracks implementation of stormwater compliance measures through the Annual Report process. Data is collected by the city throughout the year and reported to the Los Angeles Regional Quality Control Board each December. Annual Reports are available for review at the Los Angeles Regional Water Quality Control Board office in downtown LA or online at A copy of the Annual Report may also be available for viewing upon request at La Verne City Hall.
