What do Kentucky Bourbon and Sinkholes have in Common?

By: Abigail R. Hartge

Karst landscape makes delicious bourbon because of its natural filtration system.[i] However, it also creates a risk to private homeowners.[ii] Homeowners are unprotected from sinkholes unless they have purchased insurance specific to catastrophic ground collapse or sinkhole coverage.[iii] But what is Karst? Its etymology originates from the German word der Karst a name given to a limestone region in Slovenia.[iv] Translated into the meaning of “landscape underlain by limestone” or gypsum, which is “eroded by dissolution, producing ridges, towers, and sinkholes.”[v] The Kentucky Geological Survey provides a map identifying regions of high potential for Karst topography—major cities include Bowling Green, Elizabethtown, Fort Knox, Frankfort, Georgetown, Lexington, Louisville, and Somerset.[vi] There are no legal requirements or mandates in Kentucky, that demand insurance companies offer or even standardize sinkhole insurance.[vii] Homeowners who are apprised of sinkhole pervasiveness in Kentucky must opt-in by endorsement, rider, or by purchasing a separate policy for a premium.[viii] Other states with high karst topographies, namely Florida and Tennessee have taken legislative actions implementing insurance requirements. [ix]

            Tennessee requires that insurance companies offer sinkhole insurance but does not make it mandatory for homeowners to purchase.[x] Florida requires that insurance companies include sinkhole protection as part of a standard insurance package.[xi] There are two types of sinkhole protection in Florida; sinkhole loss coverage and catastrophic ground collapse coverage.[xii] Sinkhole loss coverage generally occurs when it is man-made and not natural.[xiii] The second type, is “catastrophic ground collapse.” In order to qualify for protection  four criteria must be met : (1) “the abrupt collapse of the ground cover, (2) a depression in the ground cover clearly visible to the naked eye, (3) structural damage to the covered building including the foundation and (4) the [insured] structure being condemned and ordered to be vacated by the governmental agency” authorized by law to issue such an order for that particular structure.[xiv] Homeowners insurance is generally based on the value to rebuild the physical structure of a home and not the ground. [xv] Catastrophic ground collapse is the insurance policy that provides a remedy to land damage because of a sinkhole.[xvi] This is the distinguishing factor between sinkhole protection and catastrophic ground collapse.[xvii]

            In 2014, the Corvette Museum collapsed, and Kentucky’s legislature proposed two House Bills that replicated Florida’s sinkhole and catastrophic ground collapse laws.[xviii] The same year, House Bill 498 was proposed and it defined sinkhole “a landform created by a sudden settlement or collapse of earth supporting the property if the settlement .... resulted from movement rock materials” and would require insurance companies to offer sinkhole protection[xix] House Bill 576, identical to Florida’s catastrophic ground collapse law, was also proposed around the same time.[xx] The legislature was now providing legal definitions, recognizing that Kentucky has a sinkhole issue, but also proposing that insurance companies provide a remedy.[xxi] Unfortunately, both House Bills did not make it past committee and were unsuccessful.[xxii] Then in 2019, the Louisville Zoo experienced a major catastrophic event when a sinkhole occurred that was nearly the size of “three thousand six hundred and eighty nine full sized olympic swimming pools”.[xxiii] Private homeowners not covered by insurance, will experience the liability of a costly repair for a sinkhole on their property but also for the damage to their home.[xxiv] Sinkholes are highly probable issues,  so why leave this unnecessary risk un-remedied? The Kentucky legislature should revisit their House Bills from 2014 and re-introduce those bills. Having mandatory requirements that insurance companies offer sinkhole insurance in a standard package is beneficial to Kentucky and its private homeowners.
