The following definitions are taken directly from Florida Statute 627.706:
(a) “Catastrophic ground cover collapse” means geological activity that results in all the following:
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 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 structure.
Contents coverage applies if there is a loss resulting from a catastrophic ground cover collapse. Structural damage consisting merely of the settling or cracking of a foundation, structure, or building does not constitute a loss resulting from a catastrophic ground cover collapse.
(b) “Sinkhole” means a landform created by subsidence of soil, sediment, or rock as underlying strata are dissolved by groundwater. A sinkhole may form by collapse into subterranean voids created by dissolution of limestone or dolostone or by subsidence as these strata are dissolved.
(c) “Sinkhole loss” means structural damage to the building, including the foundation, caused by sinkhole activity. Contents coverage shall apply only if there is structural damage to the building caused by sinkhole activity.
(d) “Sinkhole activity” means settlement or systematic weakening of the earth supporting such property only when such settlement or systematic weakening results from movement or raveling of soils, sediments, or rock materials into subterranean voids created by the effect of water on a limestone or similar rock formation.
(e) “Professional engineer” means a person, as defined in s. 471.005, who has a bachelor’s degree or higher in engineering with a specialty in the geotechnical engineering field. A professional engineer must have geotechnical experience and expertise in the identification of sinkhole activity as well as other potential causes of damage to the structure.
(f) “Professional geologist” means a person, as defined by s. 492.102, who has a bachelor’s degree or higher in geology or related earth science with expertise in the geology of Florida. A professional geologist must have geological experience and expertise in the identification of sinkhole activity as well as other potential geologic causes of damage to the structure.
