The longtime owners of the Whole Foods Market-anchored Ridgewood Shopping Center on Wade Avenue in Raleigh have proposed one of the biggest changes to the center since Whole Foods bought the Wellspring Grocery store there in 1991. Andrew Techet , the third-generation owner of the Ridgewood shopping center at 3514 Wade Ave., has submitted site plans with the city to redevelop part of the site that will enable him to add more retail and commercial space, as well as a six-story tall apartment building and parking deck.
