The Bi-Lo box and the strip center have seperate ownership. I also believe Bi-Lo did a sale leaseback of their box so they no longer own it. I would assume that they will either go dark or finish out their lease and vacate b/c they can't compete with Harris Teeter in the Dilworth market, especially now the Ideal Way and most of Sedgefield have become high value properties. I don't think that location has high enough traffic #s to support retail, so I'd assume that the Bi-Lo site will eventually become residental.
I'm interested to see sketch ups of any proposals for that site. The only one I've seen has been from a study done by the city, calling for higher densities and increasing the height restrictions to 5 or 6 stories and the redevelopment of the entire block incorporating all uses (office, retail, multi-family).
In my opinion, Sperry Van Ness who owns one of the shopping centers on the block already, should try and buy up the rest of the block for a long term redevelopment. With East Blvd losing some of it's charm and shops/restaurants, there's an opportunity for a new area in Dilworth to offer street-front restaurants/shops and offices. It would be great to be able to put all of the unique boutiques and restaurants into one walkable site. In the wake of all the recent news, this would be VERY long term, but seems reasonable to do in phases and would definitely bring Dilworth full circle as this seems to be the last piece of the puzzle.
