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, the following trees will require removal or pruning due to their poor condition or project requirements. More details by street:
Halcyon Avenue:
- Outside No. 3: removal of Weeping Bottlebrush (poor specimen under wires with significant lean).
- Outside No. 9: removal of Lilly Pilly (poor specimen under wires with significant lean).
- Outside No. 23: removal of unidentified tree near driveway (broad low canopy multitrunked tree under wires, blocking sight lines and footpath access).
Larbert Avenue:
- No tree removals are proposed.
Chilton Parade:
- Outside No 12A: removal of Grevillea spp.(minor specimen in poor condition); and pruning of 2 x Tupelo trees for road works clearance.
- Outside No 12: removal of 3 x Ornamental Pears (recommended due to likely extent of impacts on trees).
- Outside No 13: removal of Jacaranda (minor lopped specimen under wires); and removal of agapanthus groundcover planting along proposed kerb line.
- Outside No 2 Halcyon Ave (Chilton Pde frontage): removal of Weeping Bottlebrush (minor specimen under wires); and pruning of Japanese Maple and Camellia sasanqua for road works clearance.
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.
