The united call from a number of South Fork environmental groups that the Town of East Hampton proceed no further on coastal policy until at least one top expert has signed on as an adviser is welcome. Post-Hurricane Sandy, East Hampton has been among many shoreline communities rushing to rebuild and reinforce damaged property, in many cases without taking the time to be sure the work will not do more harm than good over the long term. East Hampton Town has fast-tracked scores of permits, and more are headed to the zoning board of appeals for review.
