 This property is largely covered with woodland and fresh-water swamp making it a very diverse wetland which is home to a number of somewhat rare plant species.The campus comprises 237 buildings and 5.1 million square feet (474,000 m2) of building space.The nearly universal use of bricks in the campus's construction – estimated at 15,194,656 bricks as of July 27, 2010 – prompted students to give it the semi-affectionate nickname "Brick City," reflected in the name of events such as the annual "Brick City Homecoming."
