Clean & Healthy Creeks

Storm drain water is a major source of pollution in our drinking water, creeks, and the Monterey Bay. A storm drain is located at the end of most street blocks and are commonly mistaken (PDF) as a sewer.

The purpose of a storm drain is to direct rainwater into rivers, creeks, streams, and other large bodies of water to prevent flooding in the City. Storm drain water is not treated, and will end up in one of two places:
  • Reservoirs used for drinking water
  • Local creeks and the bay used for recreation and by wildlife
For more information, contact the Environmental Services Division at 408-776-7333 or visit the Stormwater and Urban Runoff Management page.
