ORDINARY MEETING AGENDA                                                    15 SEPTEMBER 2022


              development to withstand the short-term erosion associated with a 500-year
              average recurrence interval storm event combined with shoreline recession due to
              sea-level rise for 2100 climate change. The short-term erosion associated with a
              500-year average recurrence interval storm event combined with shoreline
              recession due to sea-level rise for 2100 climate change to be considered for the
              design as per the recommendations of the Royal Haskoing DHV report ‘Report 66
              Seaview Terrace, Sunshine Beach Coastal Hazards Assessment, reference
              PA2906-RHD-ZZ-XX-RP-Z-0001 dated 3 June 2022.
        19.   The footing system and erosion protection system must in accordance with the
              works detailed in the Tectonic report “Geotechnical Investigation, Proposed
              residence 66 Seaview Terrace, Sunshine Beach”, (Reference 21370-001-Rev 1
              dated 28 April 2022) and other supporting documents referenced in the Tectonic
              report.
        20.   The design must include the protection of the northern and southern boundaries of
              the site to prevent erosion on neighbouring properties exposing the side
              boundaries of the site to erosion. The minimum extent of the side boundary
              protection must be determined by a line drawn at 28° extending upwards to the
              west from the base of the rear point of the erosion as per the recommendations of
              Tectonic report “Geotechnical Investigation, Proposed residence 66 Seaview
              Terrace, Sunshine Beach”, reference 21370-001-Rev 1 dated 28 April 2022.
        21.   The design must be accompanied by certification by a Registered Professional
              Engineer of Queensland (RPEQ) specialising in geotechnical engineering that the
              design is satisfactory and will provide a long-term factor of safety concerning slope
              stability of no less than 1.5.
        22.   Following construction, certification must be supplied to Council by an RPEQ
              specialising in geotechnical engineering that the works have been constructed in
              accordance with the approved design.
        23.   A dilapidation survey shall be carried out of all adjacent properties and structures
              before the commencement of construction of the proposed development on the
              site.
        24.   Due to the risk of instability on the existing dune slope and the potential for
              settlement of loose sand on the adjacent properties, vibrations must be kept to a
              minimum and must be monitored during the construction of the development.
              Driven piles (both sheet piles and pile footings) are not permitted on the site.
        25.   Landscaping at the rear of the property and the crest of the existing dune slope
              shall be limited to a maximum surcharge of 5kPa unless a site-specific slope
              stability analysis is carried out to demonstrate that higher loads are acceptable.
        26.   Under no circumstances shall building materials be temporarily stockpiled in the
              area of the crest of the existing dune slope or on the slope.
        27.   Discharge of concentrated stormwater flows onto the dune slope must be avoided,
              and under no circumstances will subsurface disposal of water be permitted using
              infiltration pits.
        28.   Stormwater runoff from gutters, down-pipes, driveways, and paved areas must be
              collected and directed by pipes into the Council stormwater system along Seaview
              Terrace.
        29.   The existing dune slope and any areas disturbed by the construction of the
              proposed development shall be revegetated as soon as possible to reduce the
              potential for erosion.
