The Project
The Jarramlee Nature Reserve Remediation Project marked a pivotal step in environmental restoration, focusing on the critical rehabilitation of the natural landscape impacted by subsidence and water intrusion issues. The project's scope encompassed several civil and landscaping works, crucial among them being the construction of a lined swale leading from the bioretention pond in the southern part of the site to Ginninderra Creek. This swale was pivotal in managing subsurface water intrusion, a key contributor to the area’s subsidence issues. Additionally, the project entailed strategic remediation of areas showing visible subsidence. This process involved the excavation and removal of underground structures, filling voids with appropriate materials, re-compacting disturbed areas, and restoring the topsoil layer. An important aspect of this phase was the replanting of flora initially removed during the onset of the remediation effort, thus ensuring the restoration of the site's natural ecosystem. Landscaping and rehabilitation of areas affected by the excavation works were conducted in alignment with a Construction Environmental Management Plan (CEMP). The plan detailed the landscaping of the newly constructed swale and the re-seeding of other impacted areas, aiming to bring back the reserve's original ecological balance.
