                    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.

            Stormwater Catchment
               12. Provide comment certifying that any potential additional catchment volume
                   from the uphill property (11 Katharina Street) has been accounted for during
                   the preparation of the Stormwater Management Plan for the subject site.

            The Stormwater Management Plan’s internal drainage system has been designed for the
            effects of the development. Whilst overland flows from upstream neighbouring properties
            are possible, the potential overland volumes are unknown. However, the rear of the subject
            site is in an area of cut and will require retaining walls and subsurface drainage for the pool
            area. The plans have been updated to accommodate future connection for retaining wall
            surface and subsurface drainage to the internal drainage network, thereby managing any
            overland flows from upstream properties.


            On-site Manoeuvrability
               13. Provide an amended Turning Path Plan demonstrating that vehicles are able to
                   enter the proposed garages and exit the site in a reverse gear (or forward gear
                   if achievable) without colliding with any future landscaping or structures. The
                   additional detail must be prepared by a suitably qualified person (RPEQ –
                   Registered Professional Engineer of Queensland).

            Drawing 060 and 061 has been updated to provide this information.

            We believe that the above satisfactorily addresses the engineering matters raised in the
            information request however, should additional information be required, please contact
            our office directly.

            Yours faithfully,
