In San Antonio, Texas, blocked storm drains create flood and health hazards and are addressed by municipal stormwater and public works rules. This guide explains how to report a blocked or clogged storm drain online, what the city may enforce, who to contact, and what to expect after you submit a report. Use the official City of San Antonio reporting channels to ensure a documented response and follow-up.

How to report a blocked storm drain

When you find a blocked storm drain, collect the exact location (nearest address or intersection), note visible hazards (debris, sediment, trash, downed vegetation), and take clear photos. Submit this information through the City of San Antonio online service or the Public Works/Stormwater reporting page so crews can schedule an inspection and cleanup. After submitting, keep the service request number for follow-up and status checks.[1]

Providing a photo and nearest cross-street speeds response.

Property owners may be responsible for removing obstructions originating from their property.

Action steps after filing a report
