SUPERSEDED - Change to an Existing Approval (Construction Staging Plan) [As Published] · 132003.221132.7

                                                                                      2003/221132

      If these checks indicate that the bioretention devices require enlarging, the applicant shall
      remove lots, if necessary, from the development in order to accommodate the devices without
      affecting the public and private open space areas. If the system requires amending, an
      amended report is to be submitted to Council for checking.
53.   Monthly reports on monitoring, incidents, corrective action and plan updates are required to be
      submitted to Council. These reports are to be submitted in a form acceptable to Council and
      are to highlight any non-standard results.
54.   Any stormwater outlet to the gullies on the site are to be stabilised with appropriate energy
      dissipation and local armouring. Regular monitoring of creek erosion is required with
      appropriate corrective action specified to ensure a stable creek system. All work to be
      undertaken to minimise impacts on the Environmental Values of the creek system.
55.   The residential precincts shall be designed to incorporate, within their boundaries, all the
      necessary stormwater and water quality control devices associated with the development.
56.   The applicant will ensure that all necessary overland flowpaths for Q100 events are provided
      on site and covered by an easement where they traverse private property.
Water Quality
57.   The Developer is to install water quality control devices generally in accordance with the
      Stormwater Management Plan. Detailed staging plans and specifications, based on and
      generally in accordance with the Plan are to be prepared and submitted (after consultation
      with officers of the Council) with the relevant applications for operational works.
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.
