                                                                                               23616DA


Drainage
58.   The Developer is to complete the drainage works progressively in conjunction with development
      of the site and generally in accordance with the approved Stormwater Management Plan.
      Detailed drainage plans and specifications, based on and generally in accordance with the
      approved Drainage Plan, the EMP and these Conditions, are to be prepared and submitted
      (after consultation with officers of the Council) with the relevant applications for operational
      works.
59.   All drainage works as required by the Drainage Plan are to be provided by the developer at its
      own cost.
Water Cycle Management
60.   Following development of the site, the vegetation in the gullies shall be monitored annually by a
      suitably qualified person (terrestrial ecologist) for three (3) years so as to detect any adverse
      effect due to rainwater tanks harvesting water that would normally flow into the gullies and
      sustain the vegetation. Monitoring of the vegetative conditions of the gullies shall include
      maintaining summer and winter photographic records at several key locations (at least 3 per
      gully) in each gully, which will be maintained for the duration of the monitoring period. The sites
      chosen for monitoring, shall be representative of the major vegetation species present in the
      gully, and also of those species which may be prone to changes in the hydrological regime of
      the gully. Details of site inspections, including photographic records shall be included in a half
      yearly report to be maintained by the site’s Body Corporate. These reports will be forwarded to
      Council. If adverse effects are evident, the water harvesting rates by the rainwater tanks shall
      be modified to overcome or other appropriate contingency measures undertaken to rectify the
      problems.
Certification
61.   Certification is required from a qualified stormwater engineer/scientist that the submitted civil
      engineering drawings accurately reflect the stormwater management treatment train in the
      approved stormwater management plan. This certification is to be submitted in conjunction with
      any Operations Works (Civil Works) application.
62.   Certification is required from a qualified stormwater engineer/scientist that the stormwater
      management treatment train in the approved stormwater management plan and associated
      design drawings has been installed on site in accordance with the approved stormwater
      management plan and is functioning as designed. This certification is to be provided to the
      Council prior to the endorsement of survey plans, or prior to Council accepting the devices ‘on
      maintenance’.
63.   All stormwater drainage lines including private drainage lines (also known as inter-allotment
      drainage lines) or as otherwise approved by Council’s Manager of Land Development shall be
      inspected by closed circuit television (CCTV) at the completion of all works and immediately
      prior to acceptance ‘On Maintenance’.
      A report of the CCTV inspection, including photographic records (which includes photos & video
      recordings burnt onto a CD) of the inspection shall be submitted to the Council for approval.
      Any defects or substandard works shall be recorded and accurately illustrated on the drainage
      plan showing the location of the defect(s).
       Substandard work will not be accepted ‘On Maintenance’ and must be rectified at the applicants
       expense with a further CCTV inspection arranged once the rectification works have been
       completed.
       To this extent all CCTV inspections, including any additional inspections necessary following
       defect identification and rectification, shall be entirely at the applicant’s expense. Any costs
       incurred by Council in reviewing the CCTV inspection results shall also be borne by the
       applicant.
