The sea level on the N.C. coast is likely to rise by 1.2 feet to as much as 4.6 feet this century, a panel of scientists told a state forum today.

The estimates will be used by coastal managers for planning purposes, but they could widely affect residents too. By including sea level rise in land-management plans on the coast, for instance, areas that are likely to flood in future decades could be declared unsuited for high-density development.

The N.C. Department of Transportation is already considering the likely rise of the sea in coming decades as it designs coastal bridges and highways, officials said.
