What matters for project planning
The Lexington-Fayette Urban County Government's floodplain management program, administered under Article 19 of the county zoning ordinance, works with FEMA on flood mapping and permitting, and LFUCG's stormwater management program addresses the city's Municipal Separate Storm Sewer System. Because Fayette County sits on Inner Bluegrass karst limestone -- terrain that produces sinkholes and irregular underground drainage -- parcel-specific flood zone status, drainage requirements, and soil conditions should be verified 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 details with the appropriate Lexington authority and the provider you select beforehand.
