Coastal slopes and basin

This is the general area situated just back from the frontline coastal zone and extending inland towards the ridgetops of Waverley, Bondi and Dover Heights. The coastal conditions of salt laden winds and strong on-shore winds still predominate and influence the growth and success of tree planting. Many taller buildings offer some protection for the smaller and medium sized trees; however, some of the taller growing species show the effects of coastal exposure.

The areas include the ridgetops and east/south facing slopes from Vaucluse and Dover Heights, Bondi Beach and the Bondi basin, and the streets extending inward from Tamarama and Bronte beaches. The more exposed southern facing slopes are the most affected.

Streetscape Character

The streets in Dover Heights and Vaucluse generally have wide grassy footpaths with no overhead wires – good site conditions for tree planting. Around North Bondi and Bondi the smaller commercial areas also have wide footpaths with no overhead wires but many are concreted or paved with small cut-outs for existing trees. Away from these commercial areas the streets narrow in size with corresponding narrow footpaths and naturestrips; overhead wires are more common restricting the range of suitable trees that can be used

Dominant Trees

   
Common name Botanical name
Coastal Banksia Banksia integrifolia
Paperbark Melaleuca quinquenervia
Bottlebrush Callistemon 'Kings Park Special'
Bracelet Honey Myrtle Melaleuca armillaris
Tuckeroo Cupaniopsis anacardiodes

Norfolk Island Hibiscus Lagunaria patersonia


Issues and Considerations

  • Number of declining street trees (mostly New Zealand Christmas Bush Metrosideros excelsa)
  • Exposure to coastal winds and poor soil quality limits species selection
  • Low number of streets with overhead wires but views to the ocean need to be considered with species selection

Strategies

  • To create a distinctive local coastal character.
  • Improve planting conditions to increase rate of tree survival -

Actions

  • Choose trees from the accompanying table of coastal tolerant trees.
  • Increase width of planting hole to a minimum of one metre and incorporate quality native soil mix and water crystals
  • Maximise the width of concrete cut-outs for new trees and incorporate root barriers to minimise any potential footpath damage
