The next major enhancement a included the commitment to a riparian corridor, consisting of a densely planted natural creek bed along the central entry median to the campus Allée. The main Mall (or 'Allée') includes 116 hand-picked columnar 'Claudia Wannamaker' Magnolias alongside five reflecting pools and four human-scale chess boards (to represent the achievements of the school's chess team). At the northern terminus of the Mall (between the McDermott Library and the Student Union) is a pavilion-sized plaza, referred to by many students as "The Plinth".
