Adelaide Hills Council supports the removal of these trees to facilitate safe pedestrian access and road safety improvement works. The subject trees are introduced species and display various undesirable structural traits and poor overall condition, due to an extensive history of powerline clearance pruning works.

Location: The trees are situated within the western council road verge directly to the south of the new bridge crossing.

Date of Works: Tuesday 15th August 2023.

Adelaide Hills Council wishes to advise that the following works will be undertaken within Stonehenge Avenue, Stirling.

Works: Complete removal of three Salix babylonica – Weeping Willows – located on the eastern side of Stonehenge Avenue, south of the intersection of Madeline Road. (Please see the map on the reverse side of this letter for the precise location of the works).

Date of works: Monday 14^th and Tuesday 15^th August.

Time of works 9.00am – 3.30pm.

Reason for works: Tree condition assessments undertaken by Council’s arborists have revealed significant structural defects within the primary branching structure of all three trees. The previous failure of an adjacent tree of the same species has exposed the remaining trees to increased wind loading, which has increased the probability of large diameter branch failure occurring. Remedial pruning to reduce the probability of such failures would require removal of a significant proportion of the primary branching structure of all three trees, resulting in a visually unappealing form which would detract from the character of the area and be detrimental to the health of the trees. Such pruning is not in accordance with the arboricultural industry standard followed by Council, Australian Standard AS 4373-2007 Pruning of amenity trees. In the interests of public safety, full removal of all three trees has been scheduled.

Due to the significant amenity value provided by the trees to the local streetscape, this site has been scheduled for replanting in the autumn/winter 2024 planting season with a replacement species to be determined.

Vehicle restrictions: To enable the trees to be removed in a safe manner, the use of various types of large machinery is required in the roadway. As this equipment has a substantial footprint, residents are advised that access to the roadway will be restricted during the period described above. The roadway will still be open to vehicle traffic, however residents are advised that delays may occur. Emergency vehicle access through the work site will be maintained. Throughout the duration of the works a comprehensive work zone traffic management plan will be implemented.

We apologise for any inconvenience and thank you for your cooperation in this matter. If you have any questions, please contact Council on 8408 0400.
