Hidden Hills Website Stormwater Public Outreach Stormwater Management

The City of Hidden Hills believes part of maintaining a beautiful city is through the protection of our waterways. Hidden Hills is located in the Malibu Creek and Upper Los Angeles River Watersheds. A watershed sheds rainfall and runoff, including pollutants, to local storm drains, creeks, and the Pacific Ocean without being treated. It is important keep our watersheds clean so we can have beautiful, healthy, and safe rivers and beaches.

What is stormwater?

Stormwater is runoff from rainfall that drains through natural and urban areas. Stormwater flows into stormdrains, through creeks, and eventually to 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 are implemented by the city: public outreach, illicit discharge and illicit connection elimination, development planning, development construction, and public agency activities. With the implementation of these programs, the city can achieve water quality standards as enforced by the Regional Water Quality Board – Los Angeles.

And you can help!

There are many household pollutants to be aware of and ways you can prevent stormwater pollution:

  • Do not dump anything into the streets, gutter, or stormdrain inlets
  • Household fertilizers, pesticides, and other hazardous wastes are toxic for the environment. Always follow the directions on the container, avoid application before rain, and avoid runoff. Try to use environmentally friendly fertilizers and pesticides if possible.
  • Avoid washing off driveways, sidewalks, and walkways.
  • Pet waste contains bacteria. Always pick up after your pet and dispose of waste in a nearby trash can.
  • Prevent unnecessary runoff by fixing sprinkler heads or installing drip irrigation.
  • Do not litter and always place trash, including cigarette butts, in a proper waste receptacle.
  • Do not discharge pool water to the storm drain.
  • Wash your car at a car wash or where wash water will drain to a grassy or landscaped area. Car washes collect all runoff and prevent soaps from entering the storm drain system.
  • Keep an eye out for a Household Hazardous Waste collection event in your neighborhood.
  • Take Action! Volunteer at a local creek clean-up. Consider California Coastal Cleanup Day or join a Friends of the LA River Cleanup event.

To report illegal dumping or discharges, please call the city at 818-888-9281 or the county-wide hotline at 1-888-CLEANLA.
