8   INNER CAMPUS The inner campus, remnants of the Memorial Quad, consists of small scale walkways and courtyards that should be upgraded to improve pedestrian amenities within a busy part of the campus. Priority rating: 3 The inner campus links University Avenue to the Fifth Field Company Lane via an east-west walkway south of Douglas Library and the Frost Wing. The north-south walkway, from Union Street west of Gordon Hall to the west side of Benidickson Field, is less direct. The courtyard between Gordon Hall and Nicol Hall appears to be relatively unused. Within it are a couple of Birch trees in poor condition and planted too close to the building, a poor quality Spruce, a Norway Maple with girdling roots and miscellaneous scrub plantings of Lilac and Fir in the southwest corner. The trees along the walkway between Frost Wing and Clark Hall are in fair condition: an Ash and Elm requiring maintenance, and two fairly good Turkish Hazel specimens. In the courtyard behind Clark Hall are two large Ash in poor condition, planted very close to the Stewart Pollock Wing. West of the Stewart Pollock Wing are several Lindens and a specimen Dawn Redwood, in good condition. The existing narrow walkways dominated by buildings are planted with larger deciduous trees, further reducing light access. A selection of high branching, light textured, medium size trees would be better suited to these walkway spaces. The removal of the Frost Wing when the Chemistry project proceeds would provide an opportunity for redeveloping this area to create a new north-south connection and a larger central courtyard. It will also offer more light and space for plantings, thus improving the present condition of confined spaces and limited light. The trees requiring the greatest maintenance attention in this space are those between the inner campus and the east sideyards of University Avenue. Given the potential for redevelopment, new plantings should be discouraged as they would be lost or damaged by new construction.
