Delegated Report - Code - Planning OPW25 0042 · OPW25/0042

               40.    Earthworks and the implementation of erosion and sediment controls are undertaken in ways
                      which ensure flooding characteristics (including stormwater quantity characteristics) external
                      to the development site are not worsened during construction for all events up to and
                      including the 1% AEP (1 in 100 year ARI) event.
               41.    Drainage paths must be regularly inspected to ensure the sediment fences/measures are not
                      being bypassed as a result of sediment build up. Sediment laden runoff must be prevented
                      from leaving the subject site and entering neighbouring properties and/or stormwater
                      systems.
               42.    Soil exposure must be limited on the site to a distance of no more than 2m beyond the extent
                      of earthworks shown on the approved plans except where the exposed soil is effectively
                      stabilised without delay and prior to rainfall occurring.
               43.    A log book for the Erosion and Sediment Control measures and inspections must be
                      maintained by the site manager and made readily available to Council when requested. The
                      supervising engineer must verify and endorsed the E&SC measures upon their installation,
                      and periodically check these measures and the log book during construction and the
                      stabilisation stages. Any defects in erosion and sediment control devices, such as sediment
                      fences, are to be inspected and documented. Upon Inspection, the contractor is to determine
                      whether the device should be replaced or repaired. Documentation is to include how the
                      damage was caused and what measures can be implemented to reduce the possibility of
                      repeat occurrences. Any damage to either permanent or temporary water quality control
                      structures or devices is to be immediately rectified at the contractor’s expense.
                      The effectiveness of the erosion and sediment control devices must be monitored. All ESC
                      measures are to be inspected:
                      a.      at least daily (when work is occurring on site) or weekly (when work is not occurring on
                              site); or
                      b.      within 24 hours of expected rain; or
                      c.      within 18 hours of a rainfall event (i.e. an event of sufficient intensity and duration to
                              mobilise sediment on site).
                      Damage to Services and Assets
               44.    Any damage caused to existing services and assets as a result of the development works
                      must be repaired at no cost to the asset owner at the following times:
                      a.      where the damage would cause a hazard to pedestrian or vehicle safety, immediately;
                              or
                      b.      where otherwise, upon completion of the works associated with the development.
                      Any repair work which proposes to alter the alignment or level of existing services and assets
                      must first be referred to the relevant service authority for approval.
               FOLLOWING CONSTRUCTION
                      Certification
               45.    Upon completion of the work a certificate must be issued by an RPEQ certifying that the
                      works have been constructed in accordance with the Operational Works permit.
               46.    A condition report of the drainage system must be completed for agreement prior to the
                      acceptance of “On Maintenance”.
                      The condition report is to include the following CCTV inspections:
                      a.      inspection of the proposed stormwater network, commencing from the existing
                              600x600 grated field inlet (shown as “1/1” on the Approved Plans) and concluding at
                              the existing headwall outlet (shown as “OUT/1” on the Approved Plans). The inspection
                              is to include reporting on all pipes and structures.
