Minor Change Report OPW24 0125 01 (As Published) · OPW24/0125.01

               2.     BACKGROUND
               A development approval for Operational Works - Drainage Works, Earthworks, Roadworks,
               Stormwater, Clearing Vegetation under planning scheme was approved on 10 January 2025.
               3.     ASSESSMENT
               The purpose of the change is to address a number of design changes brought about by constraints
               encountered during construction.
               The principal contractor informed Council that the quality of the material in the works area was not
               suitable to satisfy the requirements of the higher order approval, particularly the pavement design
               and ‘turf finish’. The material was observed as being permanently saturated and inaccessible by
               foot and machine. It appears that the works area is located at the top of the natural subsurface
               water table which causes the ‘extent of saturation’ and ‘area of inaccessibility’ to fluctuate
               during/after inclement weather – critically this area does not ‘reduce’ or ‘improve’ during periods of
               dry weather.
               Accordingly, to satisfy the requirements of the higher order and to achieve all other design
               requirements, the following design changes were proposed:
               •    a revised pavement design incorporating a cellular geocell rock mattress to improve the
                    subgrade strength and ensure subsurface flows were not obstructed;
               •    a reduction of the turfed areas adjacent to the Giraween boundary, substituted with d50
                    200mm rock armouring with a geofabric wrap;
               •    the addition of 3 x rock swales to provide drainage relief to the fire access trail;
               •    a further reduction of the turfed area adjacent to the Giraween boundary, substituted with a
                    6m wide coir blanket planted with Lomandras;
               •    a sleeper retaining wall and fall prevention fence on the OzCare side of proposed crossing
                    1.
               The design alterations generally satisfies:
               •    the bushfire risk requirements as confirmed by the supervising bushfire consultant;
               •    the requirements imposed by the Infrastructure Agreement and higher order approval; and
               •    the requirements of the future asset owner – Council’s Natural Areas Coordinator.
               Engineering believes the works are necessary to ensure all the interests of all relevant parties are
               met (including conditions and the Infrastructure Agreement).
               3.1. Instruments for Statutory Assessment
               Under the Planning Act 2016 the application must be assessed against each of the following
               statutory planning instruments to the extent they are relevant to the development:
               •      State Planning Policy;
               •      South East Queensland Regional Plan;
               •      Planning Regulation 2017; and
               •      Noosa Plan 2020 (25 September 2020).
               3.2. Statutory Process
               The applicant has requested to make a minor change to a development approval under s78 of the
               Planning Act 2016. An application for a minor change to a development approval can only be made
               in circumstances where a change would constitute a ‘minor change’.
               The proposed change to the development approval requested by the applicant is determined to
               constitute a minor change on the grounds that:
               •      the development would not result in substantially different development
               •      the change does not include prohibited development;
