Summary

In unincorporated Boone County, Kentucky, soil erosion on subdivision grading work and on individual-lot building permits is enforced by the County Fiscal Court together with the Public Works Department and the Building Inspection Department under Boone County Code Chapter 155.

These county ordinances apply to unincorporated areas of Boone County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(A) Soil erosion on property located in unincorporated Boone County and Union and related to grading work performed as a result of approved improvement plans for subdivisions shall be the responsibility of the County Fiscal Court and the Public Works Department. (B) Soil erosion and inspection of natural drainage and drainage facilities on property located in unincorporated Boone County, Florence, and Union and related to excavation or grading work on individual lots based upon an approved building permit shall be the responsibility of the County Fiscal Court and the Building Inspection Department.

Full Breakdown

10 splits erosion enforcement by project type. Soil erosion tied to grading performed under approved subdivision improvement plans in unincorporated Boone County and Union is the responsibility of the County Fiscal Court and the Public Works Department. Soil erosion and drainage-facility inspection tied to excavation or grading on individual lots under an approved building permit, covering unincorporated Boone County, Florence, and Union, falls instead to the County Fiscal Court and the Building Inspection Department. The underlying technical standards come from the 1988 Boone County Subdivision Regulations, adopted by reference and amended since, so the county code itself sets who enforces erosion control rather than the numeric design standards.

281, and collected revenue is distributed quarterly to the department that performed the inspection; those fees exclude public sanitary sewer and water line inspections. 12 begins with oral notice followed by written notification (a citation to the contractor or a letter to the developer) whenever a property owner, applicant, developer, or agent violates an approved plan, permit, or construction specification related to soil erosion, or where required inspections were skipped; construction without proper inspection is itself a violation. A correction deadline is set, and the violator must halt work in the problem area in the meantime.

If corrective action is not taken in time and public health, safety, or welfare could be affected, the county may stop all work, perform the corrective action itself, and invoice the property owner for the cost.

Violations & Fines

If corrective action still is not taken, a criminal complaint is filed in County District Court by the zoning enforcement officer under KRS 100.991(5). Unpaid corrective-action invoices become a lien filed against the property in the County Clerk's office. Under § 155.99, violations of KRS 100.273 to 100.292, or of regulations adopted under them with no other penalty stated, are misdemeanors punishable by a fine of $10 to $500 per conviction, with each day of violation a separate offense.

Frequently Asked Questions

Who enforces erosion control on a Boone County, Kentucky construction site?
It depends on the project type. Grading under an approved subdivision improvement plan in unincorporated Boone County or Union is enforced by the County Fiscal Court and Public Works Department. Grading tied to an individual building permit, which also covers Florence, falls to the Fiscal Court and Building Inspection Department under § 155.10.
What happens if I keep grading after a stop-work notice?
Continuing after oral and written notice risks the county stopping all work in the problem area, performing the corrective action itself and invoicing you for the cost under § 155.12. Unpaid invoices become a lien on the property, and unresolved violations can bring a misdemeanor complaint in County District Court.
Are the actual erosion design standards in the county's general code?
No. Chapter 155 adopts the 1988 Boone County Subdivision Regulations and amendments by reference under § 155.01; the technical erosion-control standards live in that separate document, not in the printed Code of Ordinances.
Does this rule apply inside Florence or Union?
Only partly. Individual-lot erosion and drainage inspection under § 155.10(B) explicitly covers Florence and Union alongside the unincorporated county, but subdivision-grading erosion under § 155.10(A) is limited to unincorporated Boone County and Union.
