NEW YORK (AP) — New York City is planning to expand hurricane evacuation areas to encompass 640,000 more residents, and the number of zones will be doubled so the city can better tailor evacuation orders to the dynamics of a particular storm.


Deputy Mayors Caswell Holloway and Linda Gibbs disclosed those plans Friday while releasing an analysis of the city’s handling of Superstorm Sandy.


Details on the new zones are expected in June.


The city currently has three evacuation zones. Altogether, more than 2.3 million people live in them.


The roughly 375,000 residents of the most vulnerable area, called Zone A, were ordered to leave before Sandy. A city survey found 63 percent stayed home.


The city now plans six evacuation zones.
