DOVER, Del. (AP) — A newly released study shows that sea level rise is a statewide threat in Delaware.

A vulnerability assessment by Delaware's Sea Level Rise Advisory Committee concludes that all three counties and 31 of the state's 57 cities and towns would be directly affected by a rise in sea level.

The assessment found that 8 to 11 percent of Delaware's total land area could be inundated by a sea level rise of 1.6 feet to 4.9 feet, affecting up to 17,000 residences and 48 miles of roads and bridges.

The study identified 16 resources of highest concern, including dams and dikes, evacuation routes and industrial areas.

A final report with recommendations to help governments, businesses, and citizens prepare for sea level rise is due next year.
