Storm Water Quality

Restaurant Best management Practices

Common source of pollutants from restaurants include leaking trash bins and wash water from cleaning dumpsters, parking lots, and oil and grease spills.

When it rains, storm water can pick up and wash pollutants right into the City’s storm drainage system, which flows directly into our streams and coastal waters.

The City has developed guidance and resources to help restaurant owners, managers, and staff implement Best Management Practices (BMPs) when carrying out tasks such as disposing of trash, cleaning up spills, or handling food grease. Using these practices ensures that your business will avoid fines* and contribute to keeping our island waters clean.
