I was talking with the owner of a business in the Olde Sawmill plaza (the old Kroger strip mall on Sawmill Rd. just north of Hard Rd.) and he said CASTO is preparing to renovate the plaza and bring in a new Walmart. I found some info about it on the Olde Sawmill Civic Association website.
I have mixed feelings about it. The plaza is currently 90% vacant, and I'd much rather see Walmart redevelop a dead plaza than build on a greenfield site. But traffic on that stretch of Sawmill is already a nightmare and there are several other Walmarts nearby. Also, I hope Thai Orchid stays.
