Wyandotte County, KS Environmental Rules: Erosion Control (2026)

Chapter 8, Article XIV implements the unified government's obligations under its Kansas Water Pollution Control General MS4 permit and the federal Clean Water Act. Section 8-610 finds that construction-site soil is highly vulnerable to erosion by wind and water and that eroded soil endangers water resources by reducing water quality and causing the siltation of aquatic habitat. It applies to clearing, grading, excavating, filling, storing, and disposing of soil, and requires best management practices to the maximum extent practicable even for activity that falls under the permit threshold.

Section 8-613 requires a land disturbance permit before any such activity begins, covering the permittee's contractors, subcontractors, and utility work alike, and doubles the permit fee for any site where disturbance already happened without one. Permits aren't required for projects disturbing less than a cumulative acre, unless within 50 feet of a drainage way, adding a roofed structure over 1,000 square feet, or moving 50 or more cubic yards of fill, for farming or nursery operations in agricultural zoning, for noncommercial gardens under an acre, or for emergency work.

The county engineer administers the program, can enter sites to inspect, and issues written notices of violation under Section 8-616 requiring correction within three business days before re-inspection. Section 8-618 backs enforcement with civil penalties up to $1,000.00 per violation, each day of recurrence a separate violation, injunctive relief through the chief counsel, recovery of attorney's fees and remediation costs, and criminal prosecution as a class A violation for intentional or repeat offenses.
