2   KINGSTON FIELD

The role of Kingston Field as a primary University green should be enhanced by simplified and more structured perimeter planting to define the space and maintain key views.

Priority rating: 1

Kingston Field, located over an underground parking garage, is a major campus open space and recreation ground. The existing plantings are diverse and in no particular pattern beyond forming a perimeter planting along Stuart Street and University Avenue. These offer little to define the space, frame views or reinforce the streetscape. The trees along Stuart Street are in poor condition. The existing Austrian Pines in this area have Diplodia tip blight. Shrub rose plantings are scattered and create an untidy appearance. Plantings along University Avenue are varied in species and condition, including Pine, Pyramidal Oak, Red Maple and Norway Maple. The Pine trees at the corner of University Avenue and Stuart Street are in poor form and condition, offering little to demarcate this intersection. Young oak trees in front of Kingston Hall are already showing signs of stress from poor maintenance practices and limited soil depth over the parking garage. The Ginkgo trees adjacent to the tennis courts are in fair condition; however, their roots are creating concern for the maintenance of the tennis court surface.

The key areas to address in Kingston Field are the streetscapes and the front of Kingston Hall. Existing shrub plantings along the perimeter and the Scots Pines at the east end of the field should be removed. Simple, linear deciduous tree plantings with high branching character along Stuart Street and University Avenue would reinforce the 'green' character of the space and permit views through from the field to the street. Groups of evergreens behind the row of street trees should be limited to anchor corners and frame views. The planting palette should be similar to that of Summerhill Park. The corner of Stuart Street and University Avenue, as a secondary gateway to the campus core, should be upgraded with appropriate paving and ornamental planting. In front of Kingston Hall, trees in a linear pattern would enhance this space and reflect the original tree-lined roadway planting.

A program of pruning and fertilizing should be implemented for this space to improve its condition. Any plantings on the underground structure should have a minimum soil depth of 1m and proper drainage. This can be achieved through raised planters. All trees planted in soft landscape areas should have mulched beds, minimum 600mm from the trunk, to protect them from maintenance equipment and compaction. Trees near pathways should also be protected with securely installed tree guards to prevent damage from illegally parked bicycles.
