Indianapolis manages stormwater through the Department of Public Works and the Citizens Energy Group stormwater utility. The Revised Code of the Consolidated City and County (Rev. Code) Chapter 561 and Chapter 676 govern stormwater management and drainage. Projects disturbing one acre or more require a stormwater pollution prevention plan (SWPPP) and must comply with IDEM's Construction Stormwater General Permit. The city's Stormwater Design and Specification Manual sets standards for detention, retention, and water quality treatment for new development and redevelopment.
Indianapolis enforces stormwater management regulations to prevent flooding and protect water quality. New construction and major renovations must include stormwater management plans. Impervious surface limits may apply in residential zones. Low-impact development techniques like rain gardens, permeable pavers, and bioswales are encouraged or required. Erosion and sediment control plans needed during construction. Post-construction stormwater facilities must be maintained by property owners. Municipal separate storm sewer system (MS4) permits govern city-wide discharge.
Failure to implement stormwater plan: stop-work order. Illicit discharge to storm drains: fines $500 to $10,000. Maintenance failures: notice and fines after non-compliance.
