When Wilmington Mayor Bill Saffo was growing up in the Port City, he said Wilmington handled its zoning the way most places did. “You had residential in one area, commercial in another area, and you would go back and forth,” he said. Then developers came up with the concept of people being able to live and shop closer to where they worked. And now mixed use — the newest model that government planners and developers have fallen in love with — has driven the region’s growth, including the development of Mayfaire Town Center and other mixed-use destinations. “Everything that we’re talking about or that’s in the planning process … they’re all mixed-use concepts trying to engage the local neighborhood into coming there, spending time there, eating there, having coffee there,” Saffo said.
