VALLEY STREAM - Nearly 5,000 homes and businesses in Nassau County have been repositioned on the Federal Emergency Management Agency's (FEMA) flood maps, leading to some pricey insurance changes.

Three years ago, FEMA required thousands of Western Nassau residents to buy expensive flood insurance based on their living in a high-risk flood zone. However, in revised maps released by the agency, about 4,500 residents have been removed from the zone.

Some people still located in the zone say they've never had water issues, but are forced to pay for the same exorbitant flood policy.

Sen. Charles Schumer (D-NY) says everyone no longer in the flood zone is entitled to a reimbursement for money spent on insurance. Those still in the flood zone who don't think they belong there can appeal the new maps. 

FEMA officials say the maps were redrawn to help people protect their homes, especially in the wake of Hurricane Sandy.
