Ongoing

Naturalisation of a drainage line with creek filtration/wetland/stormwater disconnections at piped stormwater outlets.

Stormwater quality improvement, aesthetic and habitat/connectivity along the creek corridor.  Attempts were made through the design to integrate the waterway into the park location using stepping-stones and planting arrangements.

Problems and constraints from sewer infrastructure despite comprehensive consultation - QUU carried out works and dug up a section of the creek not long after completion of the works. Initial period of weed control is very important in the 6-12 months after initial planting. The use or facilitation of natural regen is efficient and cost effective. Post excavation a capping clay/soil layer appears to have been broken resulting in elevated groundwater levels and creation of a wetland instead of filtration system unintentionally.
