60-ft plus deep sinkhole in Frostproof takes a carport, threatens a house

Dozens of Sinkholes in Plant City, Florida after Farmers Pump Extra Water Trying to Protect Crops from Bitter Cold

60-ft plus deep sinkhole in Frostproof takes a carport, threatens a houseIn early January of this year, Florida experienced some unusually cold temperatures that forced Plant City area strawberry farmers to pump extra groundwater to try to protect their crops. Over the course of about 11 days, the groundwater table in areas of Plant City was lowered by as much as 60-ft.

Almost immediately as many as 80 sinkholes began opening up around that region. Including ones that jeopardized a 500,000-gallon water tower, several that shut down an elementary school and numerous ones that shut down roads and highways and affected individual property owners. Around 20 local homeowners were left homeless after sinkholes left their house uninhabitable. For comparison, based on data from Florida Department of Environmental Protection’s Sinkhole Database for the period of 1998 to 2008 (the last year for which data is available), 77 sinkholes were reported to have opened up in Polk, Pasco and Hillsborough counties combined.

Local officials are seeking help from the State and FEMA to cover the estimated $3 million in damages.  That figure is double what Plant City received from FEMA for the particularly bad 2004 hurricane season. And that dollar amount does not include what individual homeowners and property owners will be seeking from their insurance carriers. (Photos by Tampa Bay Online)

Excavator mounted drilled shaft rig topples over in Austin, Texas

Drilled Shaft Rig Topples in Austin, Texas [Video]

Excavator mounted drilled shaft rig topples over in Austin, Texas An excavator mounted drill rig drilling shafts as part of a project to pass utilities under I-35 near 51st Street toppled over while trying to move in soft, rain soaked soil. The Austin Fire Department was able to extract the operator from the cab and he was taken to a local hospital with minor injuries, a minor miracle. I’m not sure what the purpose of the drilled shafts were for. Since the project was for some kind of utility pipe jacking under the freeway, I’m speculating it was drilling holes for temporary shoring for the jacking pit or something along those lines. I’m sure OSHA will be looking into the incident. Video news story after the break. (Photo from Austin
