As you’ll read in this month’s cover story, a joint venture is banking on health care as a key ingredient in a long-awaited, mixed-use project in Gloucester County. Consider that the 35-acre development, known as Washington Square Town Center, includes a 40,000-square-foot medical office building as a way to balance the amount of retail on the site. The plan also calls for a 110-bed assisted living facility, which will provide the tax revenue that might otherwise come from a more traditional commercial use.
