Are sinkholes happening more often?

Tuesday, January 8, 2019

The number of sinkholes reported in Florida has steadily increased over the last 20 years, primarily due to these side effects of a growing population and land development:

  • Increased withdrawal of ground water
  • Surface water diversion due to new structures and paving
  • Construction of ponds and regrading of surface soil

This contributes to water table reduction and concentration of rainwater runoff in smaller areas which, in turn, speeds up the deterioration of the karst underlayment of the soil—especially where the soil layer is sand and less than 25 feet deep.

    Sunken areas of ground, ominous cracks in your home, jammed doors and windows, and sediment that appears suddenly in well water are all considered early indications of a possible sinkhole developing. But these problems can also be caused by several other geological and manmade problems. See our blog post What are the warning signs of a sinkhole? to learn more.
