Waynesville, MO Environmental Rules: Erosion Control (2026)

Chapter 410, Land Preservation, adopted by Ordinance No. 985 on June 17, 1999, requires a land disturbance permit under Section 410.070 for any land disturbance activity, including street and utility construction, on a site larger than two acres; agricultural land clearing is exempt except for mechanized removal of trees over two acres. Section 410.080 then sets the erosion control content of that permit: a soil erosion control plan must accompany the application, consisting of a site grading and drainage plan and a narrative report describing the scope of work, and the plan must be prepared and certified by a professional engineer licensed in Missouri.

The section requires erosion and sedimentation control measures to follow best management practices, and it sets a firm stabilization deadline: all disturbed surfaces must be stable and non-erosive within the lesser of 30 working days or 120 calendar days after the permitted work is finished. If the work involves a building, the City withholds the certificate of occupancy until the surfaces are stabilized, though Section 410.080 allows a performance bond in place of stabilization when the season makes ground cover impossible. Sections 410.090 and 410.100 flesh out the plan's required drawings, drainage maps and narrative content, all administered and enforced by the Building Official under Section 410.060.

A site of two acres or less, or an individual lot in the R-1 or R-2 Districts, is exempt from the full land disturbance permit but must still show erosion control provisions and grading limits on the plot plan before a building permit issues.
