ISLIP - Five FEMA teams were out on Long Island Wednesday assessing the damage from last week's torrential downpours.

News 12 Long Island has learned more than 1,500 homes were damaged in the storm that brought flooding and 13.5 inches of rain in a few hours. Officials are assessing damage to infrastructure and individual homes in the towns of Babylon, Brookhaven and Islip.

The team in the Town of Babylon focused on the Venetian Shores area of Lindenhurst. There are reportedly about 900 damaged homes in that area.

In the Town of Brookhaven, FEMA assessors focused on the damage to public infrastructure, including sinkholes in Centereach.

According to officials, if federal assistance is offered to homeowners it will be on a case-by-case basis.

In order to qualify for federal funds to fix public infrastructure, the damage must exceed $25 million, and right now it is estimated to be about $30 million. Suffolk Office of Emergency Management Commissioner Joe Williams say the formula for individual homeowners to qualify is more complex because it factors in other aid and insurance.

FEMA will be on Long Island again on Thursday and Friday.
