This would consist of the usc of directional pruning techniques to develop a
single trunk and appropriate canopy up and through the spaces left between
the planter boxes. Careful selection of tree stock would also be required so
assist in the development of a single dominant leading growth point. Ongoing
tree maintenance would also consist of careful branch pruning and training to
give clearance of the podium structures over the long term.

The current size of the planting beds appears adequate for the current tree
species selected by LandGraphics. Also the design should insure that the trees
are planted at or slightly below pavement level and the raised planter beds
filled with suitable pliant species (not filled to the top with soil). If the trees
are planted at the top of the raised bed this creates future problems with major
woody roots impacting the walls and with carly establishment of the trees.

Designing for Trees

Given the Hastings Street environment and the benefits of good tree plantings
on its amenity, reasons exist to implement the best options for tree
establishment and growth.

The site itself maybe used to establish medium sized trees (up to 20 metres
height) that compliment the building and the street, using structural .ceils-and
water catchment techniques and designs. For the street trees correct planting
spaces in conjunction with structural cells and water catchment techniques
would significantly improve the street tree establishment, growth, longevity
and the minimisation of future maintenance.

Recommendations

 

inability 16 sticce: sfilly retain them in a condition that would have a long
useful life expectancy or viability.

Future Tree Plantings

Recommendation is made that the current design with its open spaces between
planter boxes at the podium Icvel is used. Ata Minimum this would require
ongoing supervision and control by an experienced arborist to establish the
trees with minimum conflict between the canopy and planter boxes on cither
side where applicable.

As to the overall tree plantings, the use of structural celfs to provide optimum
soil volume, water collection designs, and optimum planting spaces to
accommodate trunk flare will provide the best conditions for tree growth.
Recommendation is made that the engineer, laridscape architect and arborist
create a design based on these methods.
