Why Bowling Green Has Some of the Strictest Environmental Rules in the State

Bowling Green maintains 105 local ordinances across all categories, and 4 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Bowling Green falls on the strict-to-permissive spectrum compared to other cities.

Stormwater Management

Bowling Green is a Phase II MS4 community under the Kentucky Division of Water's KPDES MS4 General Permit (KYG20) and runs its local stormwater program out of Chapter 21 of the Code of Ordinances. Because Bowling Green sits on top of a karst aquifer with sinkholes, caves, and underground streams, every drop of stormwater eventually finds the groundwater — so the City treats stormwater quality as a groundwater protection program, not just a surface-water program. The program is administered by Public Works Stormwater Management at 1011 College Street, (270) 393-3628.

Key details: Governing Code: Bowling Green Code Chapter 21 (Stormwater). MS4 Permit: KPDES Phase II Permit KYG20 (KY DOW). Geology Driver: Karst aquifer — sinkholes, caves, dry wells. Six MCMs: Per federal Phase II MS4 framework. Illicit Discharge: Prohibited under Sec. 21-2.04.

Illicit discharge violations under Chapter 21-2.04 are subject to fines of up to $2,000 per offense, with each day a violation continues counted as a separate offense. Unauthorized alteration of stormwater flow into a sinkhole or dry well in violation of Section 21-3.01(b) can trigger Stop Work orders, a withholding of the Certificate of Occupancy, restoration at the violator's expense, and Class V injection well enforcement by EPA Region 4 under 40 CFR Part 144. Repeat or willful discharges into karst features that reach the drinking-water supply can also be referred to KY DOW for additional state enforcement under KRS Chapter 224.

This is one of the stricter rules in Bowling Green's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Grading & Drainage

Grading and drainage in Bowling Green is regulated through Chapter 21 of the City Code and Appendix B (Stormwater Management Guide) of the Warren County Subdivision Regulations. The CRITICAL rule is Section 21-3.01(b): any alteration that changes stormwater flow into a sinkhole, drainage crevice, dry well, ditch, closed system, catch basin, or other drainage facility — natural or constructed — requires prior written approval from the Public Works Director or designee. Detention and retention basins must be sized for the 100-year storm.

Key details: Governing Code: Bowling Green Code Ch. 21 + Warren Co. Subdivision Reg. App. B. Karst Rule: Sec. 21-3.01(b) — prior approval to alter any drainage flow. Design Storm: 100-year for detention and retention. Dry Wells: EPA Class V injection wells — must be registered. Post-Construction WQ: Sec. 21-2.05 — 80% TSS removal goal.

Altering stormwater flow into a sinkhole or dry well without Public Works approval violates Section 21-3.01(b) and can trigger Stop Work orders, civil penalties up to $2,000 per offense per day under Chapter 21, restoration of the karst feature at the violator's expense, and a withholding of the Certificate of Occupancy. Unauthorized Class V injection wells face EPA enforcement under 40 CFR 144 with federal civil penalties up to $25,000 per day. Concentrated runoff that floods or undermines a neighbor's property can expose the owner to nuisance and trespass liability under Kentucky common law. Post-construction water quality failures under Section 21-2.05 are enforced through the Bowling Green Code Enforcement and Nuisance Board under Chapter 2-21.

Compared to other cities, Bowling Green takes a harder line on grading & drainage. The enforcement and penalty structure reflects that.

Erosion Control

Bowling Green requires Erosion Prevention and Sediment Control (EPSC) measures on every land-disturbing activity of 750 square feet or more under City Ordinance 21-2.03. An EPSC plan signed by a City Certified EPSC Contractor must accompany the permit application. Sites disturbing one acre or more must also develop a full Stormwater Pollution Prevention Plan (SWPPP) and enroll in the Kentucky KPDES Construction Stormwater General Permit (KYR10) administered by the Kentucky Division of Water.

Key details: Governing Code: Bowling Green Code Sec. 21-2.03. EPSC Plan Trigger: 750 sq ft of land disturbance. SWPPP Trigger: 1 acre (or part of common plan). State Permit: KYR10 KPDES Construction Stormwater (KY DOW). Plan Signature: City Certified EPSC Contractor required.

EPSC violations under Chapter 21 are enforced by the City Stormwater Inspector and can trigger Stop Work orders, civil penalties up to $2,000 per offense per day under the stormwater chapter, and a withholding of the Certificate of Occupancy until disturbed areas are stabilized. Sites of one acre or more operating without an active KYR10 permit face additional Kentucky Division of Water enforcement under KRS 224.70-110 and 401 KAR 5:055, with civil penalties up to $25,000 per day per violation. Sediment discharged into a sinkhole or dry well can also trigger EPA Class V injection well enforcement under 40 CFR Part 144.

This is not one of those rules that cities tend to ignore. Bowling Green actively enforces its erosion control requirements.

Flood Zones

Bowling Green is a participant in the National Flood Insurance Program (NFIP) and the Community Rating System (CRS) for flood-insurance discounts. Floodplain administration is run jointly with Warren County through the Warren County City County Planning Commission, with Floodplain Manager Jacob Merriman at 1141 State Street, (270) 842-1953. Regulated areas are the FEMA Special Flood Hazard Areas (SFHAs) along the Barren River, Drakes Creek, and the city's many karst tributaries and interior streams. Any development inside the SFHA requires both a local floodplain development permit and a Kentucky Division of Water Stream Construction Permit under KRS 151.250.

Key details: Local Administrator: Warren County CCPC — Jacob Merriman, Floodplain Mgr. Contact: 1141 State Street — (270) 842-1953. State Authority: KRS 151.250 + 401 KAR 4:060 (KY DOW). NFIP/CRS: Community participates — flood insurance discounts. Main Watercourses: Barren River, Drakes Creek + karst interior streams.

Building, filling, or substantially improving a structure in the SFHA without a floodplain development permit violates the joint local floodplain ordinance and is enforced through the Warren County City County Planning Commission and the Bowling Green Code Enforcement and Nuisance Board (Code Section 2-21). Violations of KRS 151.250 / 401 KAR 4:060 expose the project to additional state penalties under KRS Chapter 224, with civil penalties up to $25,000 per day. Federal consequences are larger: a noncompliant structure jeopardizes the entire community's NFIP eligibility and its CRS rating; the property can be subject to FEMA Section 1316 denial of flood insurance; and the owner can be disqualified from federal disaster assistance. Lenders typically refuse to close on properties in the SFHA without compliant elevation certificates.

Compared to other cities, Bowling Green takes a harder line on flood zones. The enforcement and penalty structure reflects that.

The Bottom Line

Bowling Green is tougher than many cities when it comes to environmental rules. Out of the 4 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Bowling Green, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Bowling Green's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
