What matters for project planning
The City of Bowling Green's Public Works and Stormwater Quality programs note directly that Warren County sits in a karst region typified by caves, sinkholes, springs, and underground streams, with very few surface streams to carry away runoff -- which is why the city requires erosion-control and post-construction stormwater plans for qualifying land-disturbance projects. Because karst terrain can produce a sinkhole on one property while a neighboring parcel shows no issue at all, parcel-specific soil, drainage, and flood conditions should be verified with the city before foundation, grading, or exterior work begins.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, permit requirements, karst/soil conditions, or concealed construction. Check those specifics with the relevant Warren County office and with whichever provider you choose before any work starts.
