Marion County regulates grading and drainage under Indianapolis Revised Code Chapter 561 and the Stormwater Specifications Manual. Land-disturbing activity over 1 acre requires a stormwater permit. Drainage cannot be redirected onto adjacent properties.
Indianapolis-Marion County enforces grading and drainage under Rev. Code Ch. 561 (Stormwater Management) and the Stormwater Drainage Design and Technical Specifications Manual administered by the Department of Public Works (DPW). Land disturbance of 1 acre or more triggers an MS4 stormwater permit under Indiana Rule 327 IAC 15-5 and requires a Stormwater Pollution Prevention Plan (SWP3). Smaller projects must still comply with erosion control and the Indiana common-enemy drainage rule as modified by IC 36-9-27 (county drain law). Retaining walls over 4 feet require a building permit and engineered plans through the Department of Business and Neighborhood Services (DBNS). Grading cannot alter the natural flow of surface water to cause damage to adjoining parcels. Regulated drains fall under the Marion County Surveyor's Office.
Unpermitted land disturbance: stop-work order plus fines up to $2,500 per day under Rev. Code §103-52. SWP3 violations reported to IDEM. Neighbor drainage damage: civil liability under Indiana common law.
