Use the city reporting portal or Public Works contacts listed on the official stormwater page [1]. For ordinance text and regulatory authority, see the city code [2].

Report quickly and include photos to help investigators.

What the city inspects and enforces

Inspections target illicit discharges, unauthorized connections to the storm system, sediment from construction, and industrial stormwater noncompliance. Enforcement is handled by the City of Sioux Falls Public Works and associated stormwater program; the controlling ordinances are available on the municipal code page cited below [2].

The city enforces stormwater and illicit discharge rules through administrative and civil mechanisms. Specific fine amounts or per-day penalties are not specified on the cited city pages; consult the municipal code link for exact language [2].
