Report a Spill or Illegal Dumping in a Creek or Storm Drain

An illicit discharge occurs when pollutants or non-stormwater materials enter a creek or storm drain system, which is designed to carry only rainwater to local waterways. Common examples include oil, chemicals, paint, yard waste, or even sewage, which can severely harm water quality and local ecosystems. If you witness a spill or see illegal dumping into a creek or storm drain, it's important to report it immediately. Quick action can prevent contaminants from reaching our local creeks, helping to protect the environment and maintain clean, healthy waterways for the community.
