Storm Drain Inlets
There are approximately 30,000 storm drain inlets within the City of San José’s right-of-way, and each one flows to a creek, river, or the Bay. Check the watershed maps to see which watershed you’re located in and the creek your storm drains flow to. The City marks storm drain inlets with a “NO DUMPING” message that includes the name of the waterbody that the inlet drains to and stormwater hotline phone number, (408) 945-3000. Look for them in your neighborhood!
