18   QUEEN'S CRESCENT AND STUART STREET WEST Queen's Crescent is a curvilinear former residential street that serves as an important east-west pedestrian route. It would benefit from a consistent street tree planting to reinforce the street edge and lend a stronger sense of unity to the present inconsistent building edge and curvilinear road. Stuart Street West is more residential but may be in transition to institutional scale buildings when the block east of Lower Albert Street redevelops. New plantings should be coordinated with future construction plans. Priority rating: 2 The plantings along Queen's Crescent are as variable as the built form. Many of the trees are old street trees and have suffered damage from the ice storm. The large elm in front of Stirling Hall had been in extremely poor condition and finally fell. Most of the street trees are Red and Silver Maples and, given the scale of the street, they would have in the past created an impressive canopy enclosure. The Silver Maples are in poor condition. New plantings of Maple species, Ginkgo and Horse Chestnut have been started. The two Horse Chestnuts planted too close to Stirling Hall should be moved to a more suitable location while they are still young. Stuart Street west of University Avenue is more residential in scale and lined with many old Silver Maples which contribute to its charm and character. Many of these trees are in poor condition or declining health. The Lindens in front of Adelaide Hall also require pruning to accommodate overhead wires and cabling for structural support. The Walnut trees on the north side at Albert Street are dead or in poor condition and should be removed. The goal for Queen's Crescent and Stuart Street West would be to reestablish the street tree planting, with adjustments for new building edges and entrances in the proposed Chemistry Building and the Agnes Etherington Art Centre, and the potential redevelopment of the Arts Quadrangle. The landscape at the east end of Queen's Crescent at University Avenue should be upgraded. There are a number of opportunities along both sides of the street to initiate new interplantings, as has been started in front of Chown Hall. New tree plantings may be of a variety of species, but a consistent edge along the road should be maintained. Future widening of sidewalks should also be considered in establishing the standard street tree setback. New plantings require careful siting to ensure optimum growing conditions. Trees should only be planted where they will have sufficient space to grow. General pruning, fertilizing and cabling would be required for trees along this street. The plantings in front of Watson and Harrison LeCaine Halls are overcrowded and in poor condition. Some removal and severe pruning is required.
