Greenwood, IN Environmental Rules: Erosion Control (2026)

Sec. 9-157 requires a SWPPP with erosion and sediment control measures and materials-handling procedures as part of a project's construction plans. Individual lots expected to disturb one acre or more must file their own notice of intent and apply to the Board of Stormwater Management for a stormwater management permit. Lots disturbing 10,000 square feet or more but less than one acre need an erosion and sediment control permit, which costs $100 under the City's Sec. 4-66 fee schedule, before a building permit issues under the Greenwood Building Code at Sec.

7-1 et seq. Lots disturbing less than 10,000 square feet inside a larger permitted project fall under that project's approved SWPPP instead of needing their own permit. The ordinance exempts agricultural tillage and planting, silvicultural activity, oil and gas operations, and regulated-drain ditch maintenance under I.C. 36-9-27. Once work starts, a trained individual acceptable to the Stormwater Department must inspect the site by the end of the next business day after every measurable storm, or at least weekly if no storm occurs, until the site is stabilized and a notice of termination is issued. The Stormwater Department and Community Development Services may inspect at any time and charge an inspection fee under Sec. 9-161(l) and (m).
