For both summer revelers and Rockaway commuters, the key takeaway from the MTA’s new report on storm preparedness is that the Sandy-damaged A train is set to connect to the Rockaways by May 30. However, the city will still mostly rely on sandbags and plywood to fend off floods in the near future, as the MTA’s proposed higher-tech plans for protecting the system — which include “aboveground floodwall panels” and “inflatable plugs” — won’t be ready by the time the next hurricane season rolls around.
