Governor Chris Christie says New Jersey is adopting the advisory flood maps released last month by the federal government to help guide rebuilding following Sandy.
The maps establish new standards for rebuilding along the Jersey Shore. They show a much higher risk of flooding in some areas than the old maps did and establish tougher standards for rebuilding, including higher elevations.
The Federal Emergency Management Agency expects to take 18 to 24 months to adopt the standards. Christie says it did not make sense to use old maps to guide New Jersey's rebuilding or wait for FEMA to formally adopt its standards.
The maps cover 194 municipalities in coastal areas.
Christie says those who don't rebuild according to the new flood map standards could see significantly higher insurance costs.
