Project details

Planned Improvements

  • Road surface and crossfall/camber optimisation
  • Drainage system upgrades (pits & pipes)
  • New concrete installations (dish drains, kerb ramps, footpaths)
  • Construction/reconstruction of barrier kerbs and kerb & gutter
  • Reconstruction of standard laybacks (flat part of kerb) and vehicle crossings
  • New road signage and markings installation

Tree Management

Our design prioritises preserving high-value street trees identified by Council's Consultant Arborist. However, some tree removals are necessary due to their poor condition or project requirements. More details by street:

Halcyon Avenue:

  • Outside No. 3: removal of Weeping Bottlebrush (Callistemon viminalis)
  • Outside No. 9: removal of Lilly Pilly (Acmena smithii)
  • Outside No. 23: removal of large unidentified tree adjacent to driveway

Larbert Avenue:

  • No trees will be removed

Chilton Parade:

  • Outside No. 12A: removal of Grevillea
  • Outside No. 12: removal of 3 Pyrus trees
  • Outside No. 13: removal of Jacaranda tree and agapanthus planting along kerbline
  • Outside No. 2 Halcyon Ave (Chilton Pde frontage): removal of Weeping Bottlebrush and pruning of Japanese Maple and Camellia sasanqua

As part of our commitment to maintaining and improving our urban canopy, a replacement tree planting program using suitable species will be implemented when the project is completed.

Timeline

Construction is scheduled to begin in late 2025, with progressive implementation across all three roads.
