Muncie, IN Environmental Rules: Erosion Control (2026)

Muncie City Code Section 164.16(B) requires any land alteration that strips vegetation, including re-grading, to be done in a way that minimizes erosion. Natural vegetation must be retained, protected, and supplemented whenever feasible, cut-and-fill work must be kept to a minimum so it conforms to the existing topography and creates the least potential erosion, and the time an area stays exposed must be kept to a practical minimum, with stabilization happening as quickly as practical. Section 164.16(C) requires temporary vegetation or mulching to protect exposed areas while a project is under construction, and Section 164.16(D) requires permanent vegetation or structural erosion-control devices to be installed as soon as practical afterward.

Section 164.16(E) then addresses runoff directly, requiring sediment in runoff water to be trapped using methods such as debris basins and silt traps until the disturbed area is stabilized. These standards connect to the drainage permit process in Section 164.05, since a certified drainage plan submitted under Section 164.13 must describe the erosion control methods a project will use. The Board of Public Works and Safety adopts more detailed regulations implementing these minimum standards under Section 164.17, and the city engineer's office administers compliance alongside the Muncie Sanitary District engineer on larger sites.
