Wilmington sits on a series of coastal terraces that slope toward the Atlantic and the Intracoastal Waterway, creating significant elevation variation across the city. Some neighborhoods sit 10 to 15 feet above sea level while others only a few miles inland reach 40 to 60 feet, which directly affects how storm water drains and where erosion occurs. Communities along Airlie Road, Porters Neck, and Ogden represent the range of terrain conditions crews encounter, from low-lying waterfront parcels to elevated inland lots with different drainage needs. New development continues to push into former farmland and forested tracts in the northern and western parts of the city.
