RFI engineering - 20230504 RFI response

            Survey of the downstream pit will be required with detailed design, however there is
            currently sediment build up within the pit which will require pressure jet cleaning to
            determine the invert and final connection level.

            Issue: Sustainable Building Design Code
            9. Provide updated plans and a SWMP which incorporates rainwater collection and reuse at
            the site, sufficient to supply external non-potable fixtures such as communal landscape
            irrigation and bin washdown.

            The plans and SWMP have been updated to demonstrate the rainwater collection and reuse
            proposed for the site. As described in the report, 11 units would nominally require a
            33,000kL reuse volume to comply with the accepted outcomes of the sustainable building
            code. The development proposes a total reuse capacity of 50kL of reuse storage in addition
            to the 50kL of rainwater attenuation proposed.

            Issue: Landscape Setbacks
            10. Provide plans or information demonstrating that meaningful landscaping in the form of
            tree species can be planted and maintained in the bio-retention swale. Specific attention is
            to given to screening of the building, common areas, driveways and retaining walls on site.

            The bioretention depth has been increased to a nominal 1m depth of filter media to ensure
            deep rooting plants and trees are able to be established within the bioretention swale. For
            further information, refer to the town planning response and architectural landscaping
            plans.

            11. Provide further sections/plans that detail the contours and levels of the adjoining site
            at 9 Myall Street in relation to the earthworks, retaining walls and fences proposed.

            The sections and plans have been updated information about the levels in the adjacent
            property. LiDAR data from the Noosa-Gympie 2015 aerial survey project has been used to
            supplement the survey data to provide this information. Due to the nature of LiDAR data,
            there are some minor discrepancies between the survey and lidar data levels, however for
            information purposes the data is considered to be suitably representative of the local
            conditions.

            Issue: Waste Management

            16. Provide a waste management plan for the site demonstrating that sufficient area is
            available on site for both general waste and recycling bins.

            A waste management plan addressing this request has been prepared for the development
            and is included within the attachments.
