ORDINARY MEETING MINUTES                                                         19 NOVEMBER 2020


    6.    The proposed Detached House must not exceed a maximum height of 8m from the
          natural ground level and finished ground level, as shown on the North Elevation, Drawing
          No. DD 2.1, Revision A and the South Elevation Drawing No. DD 2.2, Revision A. The
          height of the Detached House from natural ground level and finished ground level shall
          be certified by a licenced surveyor before the issue of a final classification for the dwelling
          by the building certifier. The certification must be submitted to Council.
          Geotechnical Stability
    7.    A footing system and erosion protection system must be designed 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 of stabilisation measures must be that shown on Figure
          8-3 of the 2019 Omtrek report “Working Notes: Mason v Noosa Shire Council - 54
          Seaview Terrace, Sunshine Beach”, (Reference J0033 R1, 11 May 2019).
    8.    The footing system and erosion protection system must in accordance with the works
          detailed in the Tectonic report “Geotechnical Investigation, 54 Seaview Terrace,
          Sunshine Beach”, (Reference 19078-003-Rev 0, 17 July 2020) and other supporting
          documents referenced in the Tectonic report.
    9.    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 shown on Figure 8-3 of the 2019 Omtrek report “Working Notes: Mason v
          Noosa Shire Council - 54 Seaview Terrace, Sunshine Beach”, (Reference J0033 R1, 11
          May 2019).
    10.   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.
    11.   Following construction, certification must be supplied to Council by an RPEQ specialising
          in geotechnical engineering that the works have been constructed under the approved
          design.
    12.   A dilapidation survey shall be carried out of all adjacent properties before the demolition
          of the existing dwelling on the site.
    13.   Due to the risk of instability on the existing dune slope and the potential for settlement of
          loose sand on the adjacent properties, vibrations shall be kept to a minimum and shall
          be monitored during the construction of the Detached House. Driven piles (both sheet
          piles and pile footings) are not permitted on the site.
    14.   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.
    15.   Under no circumstances shall building materials be temporarily stockpiled in the area of
          the crest of the existing dune slope or on the slope.
    16.   Discharge of concentrated stormwater flows onto the dune slope shall be avoided, and
          under no circumstances shall subsurface disposal of water be permitted using infiltration
          pits.
    17.   Stormwater runoff from gutters, down-pipes, driveways, and paved areas shall be
          collected and directed by pipes into the Council stormwater system along Seaview
          Terrace. Where this is not possible, surface water should be directed to infiltrate into
          the ground around the edges of hard surfaces, with infiltration areas set back as far as
          possible from the crest of the dune slope.
                                                                                       Page 20 of 28
