Information Request MCU23 0078 [As Published] · MCU23/0078

                 order to achieve the Waterway stability design objectives is supported. Consideration should
                 be given to whether detention for events beyond the 63%AEP is required based on analysis
                 of the drainage channel in Covenant J and further downstream system.
                 Information Required
                 39.    Provide an updated SWMP and stormwater detention analysis which addresses the
                        following:
                        •    Clarify whether rainfall intensities have been increased to account for the effects of
                             climate change at year 2100, and if not provide a revised analysis for the 1%AEP
                             which includes allowance for climate change.

                        •    Consider whether detention for events greater than the 63%AEP are required based
                             on the analysis of the capacity of the drainage channel in Covenant J on Lot 1 and
                             the drainage network further downstream.
                 Issue – Stormwater Quality
                 The proposed use of an underground proprietary system for achieving the required pollutant
                 load reduction targets does not meet the requirements of PO7 of the Water Quality and
                 Drainage Code, which requires the use of natural systems and process to enhance landscape
                 and biodiversity benefits, or PO3 of the Sustainable Building Design Code.
                 Information Required
                 40.    Provide a revised SWMP and design drawings which achieve compliance with PO7 of
                        the Water Quality and Drainage Code and PO3 of the Sustainable Building Design
                        Code.
                 Issue – Water efficiency and stormwater reuse
                 PO2 of the Sustainable Building Design Code requires rainwater collection and reuse for non-
                 potable uses. This does not appear to have been addressed.
                 Information Required
                 41.    Provide updated plans and a SWMP which incorporates rainwater/roofwater collection
                        and reuse at the site, sufficient to supply external non-potable fixtures such as landscape
                        irrigation and bin washdown and internal non-potable fixtures such as toilet flushing.

                 Issue – Economic Impact Assessment
                 A review of the Economic Impact Assessment prepared by Deep End Services has identified
                 several areas where additional information is required to assess the application.
                 Further information:
                 42.    The following further information is required with respect to the EIA:
                        a) A needs assessment for the proposed cinema and indoor recreation components of
                           the development;
                        b) Update the demographic analysis such that the trade areas are benchmarked to the
                           Sunshine Coast SA4 (as opposed to Sunshine Coast LGA) and Queensland (and
                           also possibly SEQ);
                        c) Update the centres network assessment to reflect approved centre expansions and
                           note where there might be applications for centre developments or expansion within
                           the trade areas;
