Indianapolis regulates grading and drainage through its Stormwater Specifications Manual and the Consolidated Zoning and Subdivision Control Ordinance. Grading permits are required for projects that alter existing drainage patterns or involve significant earthwork. The city requires that post-development runoff rates do not exceed pre-development rates. Developers must submit grading plans showing existing and proposed contours, drainage flow paths, and stormwater management facilities.
Indianapolis regulates grading and drainage through building and engineering codes. Grading permits required for excavation or fill over specified thresholds, typically 50 to 100 cubic yards. Site grading must direct drainage away from structures and not adversely affect neighboring properties. Drainage swales, French drains, and catch basins may be required. Retaining walls over 4 feet need engineering and separate permits. Compaction testing required for structural fill. Final grade must match approved plans. Property owners responsible for maintaining drainage facilities on their land.
Unpermitted grading: stop-work order and fines $250 to $2,500. Redirecting drainage to neighbors: corrective action required. Slope failure from improper grading: liability and remediation costs.
