and Woolf Hall are of Mid-century Modern design. Attention to building design and the creation of outdoor spaces is evident with the postmodern additions of the Chemistry & Physics Building (Perkins + Will), Maverick Activities Center (Hughes Group with Page), Engineering Research Building (ZGF Architects with Page), College Park Center (HKS, Inc.), Science & Engineering Innovation & Research Building (ZGF with Page), Trinity Hall (Beck Group), and Nursing and Social Work (Smith Group). The Chemistry & Physics Building contains one of the largest and most advanced planetariums in the state. The north and east sides of campus have defined edges, being bounded by UTA Boulevard and Center Street, respectively. The south and west sides tend to blend more irregularly into the city. Cooper Street is a major artery that runs through campus and is partially depressed and spanned by three pedestrian bridges. Academic buildings erected over recent decades are on the east side of Cooper Street (defined by signage as "east campus"). Surface parking is pushed to the outer edges of campus, particularly south of the academic core, resulting in students getting more exercise than they may want during peak periods. The West Campus Parking Garage and the College Park parking garages on the northwest and northeast campus corners, respectively, provide some relief and advance the master plan goal of reducing surface parking. Green spaces, or outdoor rooms, have increased in the 2000s most notably with the creation of the Greene Research Quad, the Green at College Park, a sunken courtyard at Davis Hall, Brazos Park, and the Davis Street west campus edge. Located in various regions of campus are fiberglass horse statues with uniquely colored blue and orange patterns called "Spirit Horses." The College Park District is a $160 million development completed in 2012 that significantly expanded the campus eastward. The district has an arena with seating for 7,000 spectators, dormitory, student apartments, retail space, an 1,800-car parking garage, a welcome center, a credit union, and a 5-acre park called The Green at College Park. The on-campus resident population is over 5,000, creating a lively 24/7 environment. Large numbers of students live in Arlington Hall, Kalpana Chawla Hall, Vandergriff Hall, West Hall, and numerous on-campus apartments. The Dallas Morning News editorialized on June 23, 2012, that "UTA suddenly offers a new sense of place that surprises people who haven't taken a look for a few years." Shown below are:
