Marion County operates a separate stormwater utility under the Dept. of Public Works (Unigov). Stormwater management is governed by Indianapolis-Marion County Code and IDEM MS4 stormwater permit. Combined sewer overflows are an active concern in the White River corridor.
Marion County 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.
