More than 40,000 homeowners will need to raise their houses at least 3 feet following the new FEMA Flood Map Regulations for the State of New York. FEMA has added thousands of buildings in Brooklyn, Queens, Staten Island and Westchester County to their flood maps after their assessment following Hurricane Sandy and other recent events and now these buildings are considered at high risk of flooding. The new FEMA Maps to be adopted in 2015 will require homeowners to elevate their buildings or to skyrocketing flood insurance premiums. New York's flood maps had not been updated since the 1980's and could represent that some buildings will have to be lifted as much as 9 feet, from their actual level. It is probable that homeowners could have to pay more than 8 times their actual flood insurance premiums if they decide not to raise their properties. This actually represent a great opportunity for contractors that could received a boost from property owners as they could probably will decide to raise their buildings.
