The new maps will give homeowners a heads-up on whether their homes are in a flood-prone area.
"About 7 percent of the county is in what we call the 100-year floodplain or the 1 percent annual chance floodplain, That's a marginal increase from the old maps." said Ed Curtis, of the State Mapping Program.
For homes in the 100-year floodplain, flood insurance will be a requirement when the new maps go into effect next April.
"At that point, if you have a house that used to be out of the floodplain, you will be notified by your mortgage company and told you have to obtain flood insurance as a condition of your mortgage," said Mike Coughlin, of Wake County Environmental Services.
The premiums can range in price from $200 a year to as much as $800 a year. Officials say the higher your first floor is above the floodplain, the lower your insurance premium should be.
