Rowan County, NC Environmental Rules: Erosion Control (2026)

S. 113A Article 4 and administered by the Rowan County Planning and Development Department. Section 18-21 requires a plan approval from the county before any land-disturbing activity begins, unless the disturbed area is under 43,560 square feet, about one acre; commonly owned or jointly developed tracts are aggregated to determine whether that threshold is crossed. Section 18-23 sets the chapter's mandatory design standards: a 30-foot buffer zone must separate land-disturbing activity from any lake or natural watercourse, measured horizontally from the top of the stream bank; graded slopes and fills must be planted or otherwise stabilized with temporary or permanent ground cover within 21 calendar days of completing any grading phase; and any land disturbance over one acre requires a plan filed with the county, and simultaneously with the Rowan Soil and Water Conservation District, at least 30 days before work starts under Section 18-52.

The county must act on a complete plan within 30 days or it is deemed approved. Rowan County Planning staff periodically inspect active sites under Section 18-53 and can issue a notice of violation specifying a compliance deadline; disapproved or modified plans can be appealed to the Rowan County Board of Adjustment within 15 days of the written notice, and from there to the North Carolina Sedimentation Control Commission. Buffer, ground-cover and slope requirements apply on top of, not instead of, any stricter federal or state rule, since Section 18-21(c) directs that the more restrictive standard always controls.
