Appendix C- Serviceability Report · MCU23/0078

        The site has been identified on Noosa Shire Councils Potential and Actual Acid Sulphate Soils Overlay Map. As the proposed
        development is to undertake filling and excavation below RL20.0m AHD, it is anticipated that Acid Sulphate Soils may be
        encountered. Therefore, it is recommended that an Acid Sulphate Soil investigation be completed as part of the detailed
        geotechnical investigation conducted for the site. If Acid Sulphate Soils are present, then an Acid Sulphate Soil Management
        Plan will be required.


        All earthworks will be undertaken in accordance with the Noosa Shire Council guidelines.


3.3     ROADWORKS

        The proposed road works are as follows:

            −    Two new driveway crossovers are proposed on the private access street into the Site A lot, to provide vehicle access
                 to the basement carparking and ground-level loading docks;

            −    Two new driveway crossovers are proposed on the private access street into the Site B lot, to provide vehicle access
                 to the surface carparking and loading docks;

            −    Multiple pedestrian entrances into both Sites A and B are proposed along the private access roadway;

            −    A pedestrian walkway is proposed along the existing pedestrian access easement along the western side of Site A;

            −    A new pedestrian bridge is proposed across the environmental zone and natural drainage channel to provide
                 pedestrian access to Site A directly from the existing shopping centre to the west;

            −    All proposed road works will be undertaken in accordance with Noosa Shire Council Guidelines.

        Refer to the engineering drawings in Appendix B for further information.


3.4     SEWER

3.4.1   Existing Infrastructure

        The Unity Water As-Constructed Plans of the surrounding area indicate the following existing sewer reticulation information:

            −    An existing 225mm dia. sewer main is located below the western verge of the private access roadway at the southern
                 boundary of both development sites; and

            −    There are two existing 150mm dia. capped property connections into both Sites A and B respectively.

        The Unity Water As-Constructed Plans of the existing sewer infrastructure can be found in Appendix C of this report.


3.4.2   Proposed Infrastructure

        The proposed sewer infrastructure for this development is as follows:

            −    It is proposed to extend the two 150mm dia. property connection into Sites A and B to service the proposed
                 development; and

            −    As the surrounding roadways and services have been master-planned to service a fully developed catchment, it is
                 expected the existing sewer infrastructure has sufficient capacity to service the proposed development.

        Refer to Appendix B for preliminary drawings of the proposed sewer works.
