ORDINARY MEETING AGENDA                                                        19 NOVEMBER 2020


    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.
    18.   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.
          Earthworks
    19.   Earthworks required on-site must be carried out under Council’s Planning Scheme Policy
          PSP5 Engineering Design Standards, so as not to cause the additional ponding of water
          on any adjoining lands or concentrate or direct overland flow on to an adjoining property.
          Coastal Protection
    20.   A mix of native endemic coastal vegetation consisting of ground covers, shrubs and trees
          shall be planted for the width of the property, from the edge of the dwelling to the seaward
          boundary. The landscaping works is to be consistent with Planning Scheme Policy PSP3
          - Landscaping Plants and Guidelines. The planted vegetation must have a minimum pot
          size of 200mm and must be planted at the following density:
          a.    trees must have a maximum spacing of 5m;
          b.    shrubs must have a maximum spacing of 1.5m; and
          c.    ground covers planted between the trees and shrub stems from providing dense
                coverage.


                                                                                       Page 20 of 23
