Hendricks County, IN Environmental Rules: Erosion Control (2026)

Chapter 152 of the Hendricks County Code of Ordinances, adopted as the Hendricks County Stormwater Management Ordinance (Ord. 2023-45, passed 12-12-2023), governs erosion and sediment control on construction sites. 060 requires a SWPPP for any project under the jurisdictional authority of the County Drainage Board and/or County Plan Commission that disturbs one acre or more of land, whether through new development or redevelopment, and also captures smaller disturbances that are part of a larger common plan of development ultimately reaching one acre. Agricultural land-disturbing activities tied to normal farming practices and forest harvesting are exempt, as are certain closed landfills and permitted coal mining and municipal solid waste operations that already carry equivalent state erosion controls.

061 sets the operative policy: the developer must submit a site-specific SWPPP addressing erosion control, sediment control, and materials handling and storage, plus a construction sequencing narrative, and the SWPPP and project management log must be retained for at least three years after the project permit is terminated. Detailed technical requirements consistent with IDEM minimums are spelled out in the Hendricks County Stormwater Technical Standards Manual, available from the County Surveyor's Office. 062 governs how land disturbance acreage is calculated for coverage purposes, including rules for strip developments and multi-lot residential projects.

063. 096, the applicant must pay Drainage Board review and pre-paid inspection fees before final plan acceptance, payable by certified check, cashier's check, money order, or electronic payment to the Hendricks County Drainage Board at 355 S. Washington Street, Suite 214, Danville.
