The $90 million mixed-use plan for a site currently owned by Meriter, called Block 51, includes 400 mixed-income housing units, 20,000 square feet of retail space, 100,000 square feet of office space and more than 920 parking spaces. The project set aside 20 percent of the units for families with incomes between $25,000 and $50,000, which is considered an accomplishment due to the high cost of development in the downtown area.
