I thought so too, but when I re-read it the announcement it said
"We recognize that some of these communities may adopt and submit the required documentation of legally enforceable floodplain management measures after this rule is published but prior to the actual suspension date. These communities will not be suspended and will continue to be eligible for the sale of NFIP flood insurance. A notice withdrawing the suspension of such communities will be published in the Federal Register."
Of course the problem with the above government logic is the Fed. Register notice withdrawing the suspension is obviously going to be too late to be of any help. I didn't see anything in the notice about a confirmation of suspension, but I guess there could be an informal announcement.
First time I've ever had to deal with a Community being suspended.
