  • Stormwater Management

The City of La Puente believes protecting our waterways is part of maintaining a beautiful city. La Puente is located in the Upper San Gabriel River watershed. Rainfall and runoff flow from watersheds to local storm drains, creeks, and the Pacific Ocean without being treated. It is vital to keep our watersheds clean to ensure beautiful, healthy, and safe rivers and beaches.

Stormwater is runoff from rainfall that drains through natural and urban areas. Stormwater flows into storm drains, through creeks, and eventually into the ocean and can pick up urban pollutants along the way. The City has a National Pollutant Discharge Elimination System (NPDES) permit in which the City must take many measures to prevent stormwater pollution. The permit contains multiple programs that the City implements: public outreach, illicit discharge, illicit connection elimination, development planning, development construction, commercial and industrial facilities inspections, and public agency activities. With these programs’ implementation, the City can achieve water-quality standards as enforced by the Regional Water Quality Control Board – Los Angeles.

Be aware of these household pollutants and how you can prevent storm water pollution:

  • Do not dump anything into the streets, gutter, or storm drain inlets.
  • Household fertilizers, pesticides, and other hazardous wastes are toxic. Always follow the directions on the container, avoid application before the rain, and avoid a runoff.
  • Avoid washing off driveways, sidewalks, and walkways.
  • Pet waste contains harmful bacteria. Always pick up after your pet and dispose of waste in a nearby trash can.
  • Prevent unnecessary irrigation runoff by fixing sprinkler heads or installing drip irrigation.
  • Do not litter and always place trash, including cigarette butts, in a proper waste receptacle.
  • Wash your car at a car wash or where wash water will drain to a grassy or landscaped area. Car washes collect wash water and prevent soaps from entering the storm drain system.
  • Call 1-888-CLEANLA or visit www.lacsd.org for information on upcoming household hazardous waste collection events near you.

Volunteer at a local creek cleanup. Consider joining a California Coastal Cleanup Day or a Friends of the LA River event. 

Please call the countywide hotline at 1-888-CLEANLA or alert the City through the GO REQUEST online complaint system.
