                    a. the full extent of the transition to the adjoining areas of verge.

            Where possible the design is sympathetic to the existing conditions and localised grading
            will be used to eliminate trip hazards within the road reserve.

            External Works (Footpath)
               10. Provide an amended plan that demonstrates a 1.5m wide footpath will be
                   constructed along the frontage of the subject site that connects to the adjoining
                   existing footpaths. The amended plan must be prepared by a suitably qualified
                   person (RPEQ – Registered Professional Engineer of Queensland).

            Drawing 010 has been updated to provide this information.

            Stormwater Infrastructure Works in Road Reserve
               11. Provide additional information regarding the construction methodology of the
                   proposed stormwater pit and its’ integration into Council’s existing stormwater
                   infrastructure network. The detail should be prepared by a suitably qualified
                   person (RPEQ – Registered Professional Engineer of Queensland) and include,
                   but not be limited to:
                   a. demonstrate the extent of works required to remove the existing pit,
                       stormwater pipe and any kerb and reinstate the road and associated kerb;
                   b. demonstrate the extent of works required to install the proposed
                       stormwater pit and associated stormwater pipes, include levels (surface
                       and invert) and grades; and
                   c. demonstrate how the proposed stormwater pit will integrate into Council’s
                       existing stormwater infrastructure.

            A review of Council’s mapped stormwater network has identified that these assets are not
            captured in current Intramaps layer. Based on the site’s elevation and surrounding
            landform, it is likely that these assets are discharging into Pinaroo Park (Lot 84 on SP248300)
            detailed in Figure 2.

            The existing pit appears to be a non-standard ‘Noosa Style’ Type B pit (STD DWG 9223A)
            without the required transition lengths of 1m to kerb and channel, as shown in Figure 1. A
            new on grade lip in line inlet pit is proposed for reconstruction and connection to Council’s
            stormwater assets as there is no worsening of surface flow quantity from the development
            to this catchment. Details related to levels and grades are provided on the Stormwater
            Layout Plan.
