The state will now recognize sinkholes as threats after updating its hazard mitigation plan.

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. They’re sometimes drilled out and used to store crude oil, natural gas, or other material. A failed salt dome cavern is blamed for a 29-acre sinkhole to form in bayou Corne in Assumption Parish in August 2012.

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