re: Gating canals in houma area

It's likely part of the stipulations in the CUP, Costal Use Permit, for that parcel of property. LLE and Apache own a gazillion acres and I'm very certain said activity is not be done on most they own.
It also could be a mitigation bank they have to maintain to offset work in wetlands areas they have impacted in other parts of the state, thus they have to pay for life.
