Delegated Report - Code - Planning RAL25 0004 (As Published) · RAL25/0004

               A complete assessment against the assessment benchmarks of the code is provided below.
               The Reconfiguring a lot code does not include any minimum lot size in the community facilities
               zone. The proposal seeks to create englobo lots which are suitably sized lots for future community
               uses that will likely be subject to separate assessment via a new application. An assessment
               against the assessment benchmarks demonstrates that the proposal is consistent with the relevant
               performance outcomes sought by the code.
               4.6 Key issues
               4.6.1 Contaminated Land
               The site was identified as being a former municipal landfill site from 1912-1958. This has led to
               the site being listed on the Queensland Government’s - Environment Management Register (EMR)
               as a contaminated site. The applicant has engaged a suitably qualified environmental consultancy
               to undertake a contaminated land detailed site investigation to assist with the future redevelopment
               of the site.
               The Detailed Site Contamination Investigation prepared by Environmental advisors on 12/06/24
               (Ref: DSI 12032024 Rev 0) confirms the historic use of the site for landfill. The reporting concludes
               that site remediation (or management for less sensitive uses) will be required under all future land
               uses scenarios. As such the report recommended that a Remediation Action Plan be prepared to
               support the future redevelopment of the site.
               No referral to the State was required for this application for contaminated land matters under
               schedule 10 of the Planning Regulations as this only applies to MCU applications.
               4.6.2 Landslide Hazard
               The subject site contains mapped areas of moderate landslide hazard areas. The site drops from
               the southwestern portion of the site (in proximity to the existing shed) down to the Lake Macdonald
               road frontage at an approximate 11% slope, and to the Dianella Court frontage at an approximate
               8% slope. The mapping appears to reflect a small gully / overland flow path traversing lot proposed
               2.
               Mapped landslide hazard areas are also identified on Lot 100 near the MacDonald Rd road
               frontage and around the bioretention basin. Some minor filling is proposed to occur over Lot 2 and
               construction of the new road will be assessed as part of the subsequent associated operational
               works approval process.
               Typically, the landslide hazard mapping would trigger the requirement for a geotechnical
               assessment to be undertaken to ensure site stability and compliance with PO1. Council’s
               engineering officers have assessed the proposal and have not requested that a geotechnical report
               to ensure compliance with PO1 of the Landslide Hazard Code. This matter can be further reviewed
               and assessed as part of the future operational works application.
               4.6.3 Flood Hazard
               An area of 100m2 in the northern corner of the development is identified within the Flood Hazard
               Overlay. No new lots will be located within land identified within the Flood Hazard Overlay with the
               exception of proposed Lot 900, the future bioretention basin.
               The creation of the drainage lot does not increase the risk to people or property. The findings of
               the flood hazard assessment requires additional drainage infrastructure within this location which
               will aid in reducing inundation periods at the Lake Macdonald – Dianella Court intersection.
               The proposal does not increase the number of lots within the mapped hazard area.
               4.6.4 Biodiversity
               The southern part of the site is mapped as containing Area of biodiversity significance.
               Environmental assessment of this vegetation has been undertaken and Council officers have
               review this assessment and it is identified that the mapped vegetation is non remnant and planted
               for plantation purposes. Subsequently, Council has obtained approval to clear this vegetation as
