Achieving Living Street Trees - Planting to Ensure Longevity of Urban Trees
1 July 2010
This workshop will focus primarily on tree planting in highly urbanised streets of the city. This includes ensuring sufficient soil root volumes, allowing for gaseous exchange, providing optimum structural health and vigour of the stock supplied, and allowing good pedestrian circulation.
Topics to discuss include;
- Current North Sydney Council standards and project examples
- Species selection and structural health of trees
- Allowing sufficient time to grow stock to the designer’s specification, height, caliper, root-ball profile and under-pruning
- Allow material to be grown to Natspec standards, from starter stock right through each phase of the production cycle
- The decline of the Eucalypt in the urban environment
- Maintenance, watering requirements and vandalism.
- The workshop will also discuss the effectiveness and use of structural soils. It has been 10 years since the Sydney Olympics and there has only been limited monitoring to determine if it has really worked.
Other topics include
- General use and detailing of structural soils with examples where not to use it
- The importance of soil root volume and gaseous exchange
- Sound and safe pavements under and around healthy trees
- Structural Soil Principles, Design, Natspec and Progress
- Structural soil costs
- Incorporation of WSUD- achieving multiple goals
From all of this we would like to work towards designing a workable detail and principles to inform developers and local government in highly urbanised areas about the importance of correct planning, preparation, Installation techniques and long term maintenance of trees and structural soils including the design of pavements that allow trees to be fertilised as part of standard maintenance procedures. Finally, reviewing the current Natspec specification and providing an update that can be certified and used throughout the industry.
