These development projects can be of any size (in terms of square feet of floorspace), and fall into one of the following construction categories: new, additions to existing buildings, renovations of existing buildings, or redevelopment projects. SEMCOG also reports 10 types of development: entertainment/recreational, hotel, industrial/research/hi-tech, institutional, medical, mixed-use, office, retail/commercial, transportation/utility, and warehouse/distribution.
