Sioux Falls requires grading and erosion-control plans for land-disturbing construction activities. Subdivision drainage must meet Engineering Design Standards Chapter 7, and projects disturbing one or more acres need a state stormwater permit plus city erosion and sediment control (ESC) approval.
Chapter 157 of the Sioux Falls Code of Ordinances (Subdivisions) and the city's Engineering Design Standards Chapter 7 (Grading) govern grading and drainage. All subdivision plats must include drainage design per § 157.117 (easements) and related sections. Rear-yard drainage easements require a minimum 1% longitudinal slope. Projects disturbing one or more acres must obtain South Dakota DANR stormwater general permit coverage (NOI filed 15 days prior) and submit a Storm Water Pollution Prevention Plan (SWPPP). The City's ESC program enforces individual-lot erosion and sediment control compliance. Chapter 51 establishes ongoing storm drainage utility fees. Violations are subject to stop-work orders and penalties under § 157.007.
Violations may result in stop-work orders and civil penalties under § 157.007. State NPDES stormwater permit violations carry separate DANR fines up to $10,000 per day.
