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

Morgan County Code § 52.09 requires anyone whose construction causes an earth change in unincorporated Morgan County, Indiana to provide soil erosion and sedimentation control adequate to keep eroded soil from reaching adjacent properties, a stormwater drainage system, a public street or right of way, a wetland, creek, stream, waterbody, or floodplain. Before making the earth change on a site the subchapter regulates, the developer must first obtain an erosion control permit or a Stormwater Management Plan Approval (SWMPA); projects needing a SWMPA follow the County Stormwater Design Manual, while projects equal to or greater than a half acre submit for erosion control permit approval directly.

An erosion control permit application requires payment of the application fee and plan sheets showing existing and proposed site conditions with one-foot contours, stormwater conveyances, drainage flow arrows, utilities, building footprints, streets, drives and parking areas, easements and rights-of-way, perimeter control measures, a temporary construction entrance to limit sediment tracking, concrete washout areas, soil stabilization for bare and adjacent disturbed soils, inlet protection, and stabilization for steep slopes. A project that already has to prepare a stormwater pollution prevention plan (SWPPP) under the state's construction stormwater general permit can use that SWPPP to satisfy § 52.09 instead, but must still copy the county on its state and federal filings and post the Notice of Intent, NPDES permit number, and SWPPP location at the project site. During construction, the county or its designated representative may inspect the site to confirm the approved runoff controls are in place and working.
