Long Island officials say more than 2,000 homes were destroyed or left uninhabitable by Sandy.
In Nassau county, the number will likely reach 1,400, including more than 1,000 homes in Hempstead. In Suffolk the toll is 675 homes. Babylon was hardest hit, with more than 300 homes destroyed, followed by Brookhaven and Southampton.
Officials say the total number may grow.
According to Newsday, the homes are part of about 100,000 Long Island residences that officials estimate were severely flooded, damaged or destroyed during the storm.
Last month, Gov. Andrew Cuomo requested nearly $8.4 billion in federal aid for Long Island, including housing funding, to cover the cost of the storm.
More than 71,000 households in Nassau and over 26,000 in Suffolk have applied for FEMA help.
Cuomo requested more than $30 billion in total for New York as the state seeks to recover from Sandy's devastation.
