I have created this map of the Karst sinkholes in Florida using ESRI ArcGIS 9.3. I have also used this map as a basis for a time-lapse video, which will be posted on this webpage shortly. The State of Florida footprint, and the county footprints were created from some generic GIS data that I had found online, years ago; the sinkhole GIS data was downloaded from the Florida Department of Environmental Protection webpage about the Florida Geological Survey, Subsidence Incident Reports. The webpage a that link will prompt your for a valid email address, before you can download any GIS data about Karst Sinkholes, which they refer to as subsidence incidents.

In January, 2011, Senate Bill 408, also known as SB 408, was signed into law. This law seems to impact the residents of Pasco and Hernando Counties, the hardest. If you have property in the areas of Florida that are susceptable to sinkholes, then you should review your Florida insurance policies and the Florida Sinkhole legislation, then contact your insurance agent for sinkhole coverage, or a sinkhole attorney.

About this Webpage

I enjoy working with GIS data and try to find new things to keep my skills honed with.

Within these pages, I am performing some GIS tasks about the Karst Sinkholes in Florida. After seeing the news about the 100 foot-side sinkhole that had opened up behind a house in Windermere, Florida, I decided to see what was available for historic sinkhole data and started developing this webpage, complete with a time-lapse video of the historic locations of the sinkholes.
