Tulsa enforces comprehensive stormwater management under Title 11-A (Stormwater Management and Hazard Mitigation Program) of the Tulsa Revised Ordinances. The city operates under an MS4 NPDES permit from the Oklahoma Department of Environmental Quality (ODEQ). Tulsa's stormwater program is nationally recognized due to the city's history of severe flooding events.
Title 11-A requires stormwater management plans for new development and redevelopment. The city charges stormwater utility fees based on impervious surface area. All construction sites must implement erosion and sediment controls. The Tulsa Stormwater Management Department manages over 2,800 miles of storm drain infrastructure. Low Impact Development (LID) practices are encouraged. Development must comply with the city's Stormwater Design Criteria Manual. Illicit discharges to the storm drain system are prohibited.
Violations of Title 11-A carry fines up to $500 per day per violation. Illicit discharges may trigger state penalties from ODEQ. The city can issue stop-work orders for construction sites without proper erosion controls. Repeat offenders face escalating penalties.
