Decision Notice OPW25 0057 · OPW25/0057

               20.    The installation and/or modification of any traffic signs, street signs, line marking and Raised
                      Reflective Pavement Markings (RRPMs) must be in accordance with the Manual of Uniform
                      Traffic Control Devices (MUTCD). New or relocated signage must be installed using the VLok
                      installation system. All new signage must be Class 1 retroreflective material in accordance
                      with AS 1906.1, Retroreflective materials and devices for road traffic control purposes – Part
                      1: Retroreflective sheeting.
               21.    On street advisory cycle pavement marking must be provided at the intersection of Dianella
                      Ct and Lake Macdonald Dr in accordance with council requirements and relevant Standards.
               22.    The developer must notify Council’s Traffic Engineer for any works involving the removal or
                      modification of existing council traffic signs and/or parking bays prior to such works
                      commencing.
                      Pavement Design and Construction
               23.    The pavement designs shown on the engineering drawings are not approved. To attain
                      approval for the pavement design, the following details must be submitted and certified by
                      an RPEQ with the proposed pavement design.
                      a.      The design CBR must be based on the four day soaked CBR value for the subgrade
                              material.
                      b.      The design subgrade CBR must be representative of each homogenous insitu section
                              of finished subgrade. With respect to each section:
                              i.       For four or less test results, the design CBR must be taken as the least estimated
                                       insitu CBR result.
                              ii.      For five or more test results, the design CBR must be taken as the 10th percentile
                                       of all estimated insitu CBR results.
                      c.      The samples must be taken generally in the position of the outer wheel path on both
                              sides of the proposed road. A sketch plan showing the location of all tests must be
                              submitted with the test results for pavement design approval.
                      d.      Where imported material has been (or is proposed to be) used for subgrade
                              replacement, and the depth of the imported material is less than 300mm, the pavement
                              design CBR must be based on the testing results of the insitu material and not the
                              imported material.
               24.    At the time of subgrade inspection, the subgrade must exhibit no visible signs of deformation
                      under proof rolling by a fully loaded water truck. The pavement subgrade will not be passed
                      until this requirement has been achieved.
               25.    Pavement design for privately owned works must be undertaken in accordance with the
                      relevant standards. Structural integrity of the driveway and car park areas will remain the
                      responsibility of the property owner/developer and must be certified by an RPEQ.
                      Works within Road Reserve/Reinstatement
               26.    Safe pedestrian and vehicle access on all streets in the vicinity of the development must be
                      maintained at all times. Should footpath/road closures be necessary to carry out construction
                      works, Council’s Engineering Officer must be notified prior to the proposed closure and all
                      requirements complied with.
               27.    All frontage works must match neatly with existing road and verge/footpath features.
                      Additional works beyond the frontage may be required to provide an acceptable transition to
                      existing road and verge/footpath profiles.
               28.    The verge is to be modified such that the maximum crossfall for the verge is 5%, except in
                      the location of a pathway where the maximum crossfall is to be 2.5%.
