Information Request 132008 176 05

                       •    Explain what structures will be present over the 600mm dia emergency relief pipe
                            and how this pipe will be able to be accessed should maintenance or upgrade be
                            required in the future
                       •    Explain why a more conventional solution (eg conventional drainage and pipeless
                            bioretention) could not be adopted for the site and would not present a lower-risk and
                            lower-maintenance solution


                 Issue – Stormwater quality
                 Stormwater quality is not directly addressed in the SWMP - presumably on the basis that all
                 flows are infiltrated and hence ‘lost’. This does not recognise that groundwater is a receiving
                 environment and treatment is required prior to infiltration
                 Information Required
                 15. Provide an updated SWMP and preliminary engineering and layout plans which
                     demonstrate that stormwater quality objectives are achieved prior to discharge to
                     groundwater (i.e. prior to infiltration).


                 Issue – Grant/Banksia Roundabout Upgrade
                 Page 18 of TTM’s Traffic Engineering Report (22135916) dated 07 October 2022 details
                 design modifications of the existing Grant/Banksia roundabout and “Driveway Entry” into the
                 Resort. The submitted documentation does not contain sufficient information for Council to
                 assess the proposed Grant/Banksia roundabout upgrade and “Driveway Entry”.
                 Information Required
                 22.       Provide additional detail demonstrating the extent of the Grant/Banksia roundabout
                           upgrade and proposed ‘Driveway Entry’ into the Resort. The detail must 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 roadworks, including:
                                  i.   design alterations to the roadway, traffic islands and roundabout island;
                                  ii. signage; and
                                  iii. line-marking.
                           b. Demonstrate the extent of entrance works, including:
                                  i.   demonstrate the design of the proposed “Driveway Entry” complies with
                                       Noosa Council’s standard drawing RS-051;
                                  ii. provide a longitudinal section extending from the centreline of the road
                                      formation about the Grant/Banksia roundabout to the “Driveway/Setdown”
                                      area;
                                  iii. demonstrate B99 vehicle will not scrape or bottom out while entering and
                                       exiting the proposed “Driveway Entry”;
                                  iv. demonstrate additional stormwater runoff generated by the downward slope
                                      of the proposed “Driveway Entry” will create a worsening of drainage
                                      conditions within the road reserve and road network; and
                                  v. demonstrate the required vegetation clearing.
