Civil Engineering in Kentucky: what governs your project

Construction stormwater discharges are regulated through the Kentucky Pollutant Discharge Elimination System (KPDES), administered by the Kentucky Division of Water, including a construction general permit for land-disturbing activities. Access to state-maintained roadways requires encroachment permits from the Kentucky Transportation Cabinet. Karst terrain across much of the state demands special stormwater management to avoid concentrating runoff into sinkholes, and Ohio River floodplain development is closely regulated.

Permitting & plan check

The Kentucky Department of Housing, Buildings and Construction performs plan review for certain building types and occupancies at the state level. Local building departments handle permits and inspections in jurisdictions with their own programs. Designers should confirm early whether a project routes through state or local plan review.

Good to know

• Western Kentucky's Jackson Purchase region lies within the New Madrid Seismic Zone, with the highest seismic design requirements in the state.
• Kentucky's karst topography, including the Mammoth Cave region, makes sinkhole risk a standard geotechnical consideration for site development.
• Construction stormwater in Kentucky is regulated through the KPDES program administered by the Kentucky Division of Water.
