Construction could begin in the next 30 days on a long-awaited shopping center off Limestone and Jesse Jewell parkways in Gainesville. “We’ve been working with all the various (city) department heads and with the planning department, and we expect that over the next couple of weeks to receive all of our permitting for (starting) grading and construction,” said Michael D. McNicholas, president of developer Carolina Holdings Inc. Also, “we’re finalizing our documentation with Kroger,” the expected lead tenant in the New Holland development.
