Utilities and Infrastructure California 3 Minutes Read ยท published February 06, 2026 Flag of California

In San Jose, California, clogged storm drains and illicit discharges (anything other than stormwater entering the storm drain system) can cause flooding and water pollution. This guide explains how residents and businesses should report blockages or suspected illegal discharges, what agencies enforce the rules, likely enforcement outcomes, and the steps to follow to document and resolve problems quickly.

What to report

Report standing water, debris-clogged catch basins, visible sewage, chemical sheens, paint or oil in gutters, or deliberate dumping into storm drains. Note the exact location, time, photos or video, and any identifying details about vehicles or people involved.

Document photos and locations before moving items when safe to do so.

How to report

Provide the street address or nearest intersection, description of the problem, and any media (photos/video). City staff or contractors respond based on severity and safety. If there is an immediate health or safety hazard, call emergency services first.

  1. Call San Jose 311 or the Public Works Stormwater hotline to submit a report.
  2. Use the City of San Jose online request system when available to attach photos and exact location.
  3. If you suspect a hazardous spill, inform emergency responders and the City immediately.

Penalties & Enforcement

San Jose enforces stormwater and illicit discharge rules through the City Public Works and Environmental Services programs; the City inspects reports, orders corrective actions, and may pursue enforcement for violations. Specific fine amounts and escalation schedules are not specified on the cited City page; for official enforcement policy and contact, see the Stormwater Program contact below[1].

Applications & Forms

  • Take photos, record date/time, describe the material, and note any witness or vehicle details.
