Coastal communities and the state also have a large investment in North Carolina to protect. What do they need to plan for the next big one, the one everyone says is long overdue? Is there a better way to build a storm- resistant structure, evacuate a com- munity, predict flooding or estimate erosion? Sea Grant researchers have been looking for answers to these ques- tions and more to help North Carolina's coastal towns prepare and plan for hurricane. • Survivability was the key word in Jerry Machemehl's research work for Sea Grant two years ago. Machemehl, formerly an associate professor of marine science and engineering at North Carolina State University (NCSU), set out to design a coastal structure that could withstand the battering and brutal forces of a hurricane. But first, he looked at how buildings were being built and found many weak areas. Building codes and construction standards in North Carolina changed after the deva- stating storms of the late 50s and early 60s. Coastal property owners got the message when Hazel left. only five of 357 Machemehl buildings on Long Beach intact. New homes were elevated on pilings to clear storm tides and setback from the shoreline to prevent undermining by erosion. "Building codes were strengthened and upgraded," Machemehl says, "but they were basically minor improvements. The codes were still not designed for beach construction for the forces found in a coastal ; During his project, Machemehl did a survey of homes along the North Carolina coast and found that only 10 percent of the homes were strong in several areas he determined to be vulnerable to wind and water damage.
