Thousands of Town of Hempstead residents received a letter from the town about possibly having to elevate their homes.

It's been almost seven years since Superstorm Sandy hit Long Island. Many thought they were done with the aftermath, but now some 13,000 homeowners have been notified that their homes may need to be elevated.

The town assessed homes after Sandy for preliminary damage. The homes were given color codes with green being good and yellow or red meaning the home needs to be elevated. Those preliminary damage reports were unknown to many residents. Now, the town is telling people they need to make sure their homes are up to snuff.

Michael Cascio, of Oceanside, is one of the homeowners who received a letter. Cascio says he already went through the expense of renovating his home and now he's being told his home needs to be raised.

Cascio says he thought he was done with problems from Sandy. He says to elevate his home would be a financial burden, especially since there is no more assistance.

"I thought Sandy was in our rear-view mirror," says Cascio. "I really thought we were passed all of this and we could move forward."

Town of Hempstead Deputy Chief of Staff Rebecca Sinclair says the town sympathizes with homeowners and is trying to figure out a solution.

Town officials say some homeowners who purchased renovated homes after the storm may even have to elevate as well. The town is waiving some permit fees and is encouraging property owners in the flood zone to get their Preliminary Damage Assessment report as soon as possible.
