Louisiana flood projections require urgent action, officials say

Louisiana officials are revising the master plan for combating flooding and storm surge damage and have abandoned the projection of no net loss of land by 2035.

The new master plan, to be released in 2017, is more pessimistic than the 2012 version. State officials had thought they could stabilize land loss in the next 20 years, and then be able to add land to the coast. They now say it would take much longer to break even, and that goal may be unrealistic.
