6.5.22 - Flooding Report 5 may

      1. INTRODUCTION
      PEAKURBAN Pty Ltd have been engaged by Mark Bain to prepare a Flood Investigation in
      support of a development application to Noosa Shire Council (NSC) over land located at 60
      60 Glenridge Drive, Cooroibah (Lot 47 RP 860577). This development application seeks a
      development permit for a Reconfiguration a Lot (ROL) to create 8 rural residential lots.
      The proposed outcome of this investigation is to inform the layout design with respect to
      managing flood impacts, demonstrate non-worsening and sizing of cross-drainage culverts in
      order to achieve the requirements and targets of NSC Planning Scheme “Flood Hazard Overly
      Code”.
      The proposed Plan of Subdivision and concept engineering plans can be found in Appendix
      A.

              Site Location
      The location of the proposed development site is shown in Figure 1-1.

      The site is influenced by two unnamed tributaries of the Noosa River. Both catchments
      extend upstream across McKinnon Drive to the west and join at the eastern boundary of the
      site. The total catchment of both tributaries is 130ha. The catchment is characterised by
      steep upper catchment and flattens out along the lower part of the flood plain. Elevations
      on site range from 10 to 44m AHD.

      The site is located within the mapped NSC Flood Hazard Overlay (refer Figure 1-2).
