In Nassau county, the number will likely reach 1,400. In Suffolk the toll is 675 homes.
Officials say that number may grow.
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.
