State to include sinkholes in disaster planning

THIBODAUX, La. (AP) – Sinkholes will be recognized as threats in the state’s updated hazard mitigation plan.

The Daily Comet reports  the state is working on a five-year update to its hazard mitigation plan, which must be in place to receive federal money after natural and man-made disasters.

For the first time, the state will map salt domes and their surrounding 2-mile radius in each parish.

Salt domes are pockets of salt deep in the ground that are sometimes drilled out and used to store crude oil, natural gas or other material.

A failed salt dome cavern is suspected of causing a 29-acre sinkhole to form in Bayou Corne in Assumption Parish in August 2012.

The hazard mitigation plan also covers threats from floods, levee breaks and coastal erosion.
