2. Council also requires the ASSMP to be amended to address all relevant requirements of
   SPP 2/02. In particular, SPP2/02 requires that monitoring strategies and schedules be
   detailed within the ASSMP for surface water and groundwater monitoring (for pH, electrical
   conductivity, salinity, dissolved oxygen, sulfate, total iron, dissolved iron, filtered aluminium
   etc.) and field soil monitoring for field pH (pHF), pH after oxidation with hydrogen peroxide
   (pHFOX) and reaction with peroxide etc). In providing this response the monitoring schedule
   must reflect changing site conditions with respect to potential changes in soil and water
   quality characteristics during the progress of excavation activities.

3. Please justify the relevance of the water quality criteria stated for the site in the ASSMP.
   Also provide the reference source for the stated water quality criteria.

4. Please indicate measures that will be implemented to ensure groundwater and ponded water
   is not released into the environment prior to effective treatment.

5. Please detail corrective measures that will be implemented in the event performance
   indicators of the ASSMP are breached.

6. Please provide a plan showing borehole locations referred to in the ASSMP.

7. Given that ASS are expected to be encountered as a result of proposed excavations,
   provide an assessment by an appropriately qualified person of the effects of saline,
   sulphurous or acid soil or groundwater upon proposed structures or any other services.

   Stormwater
8. Please indicate the direction of stormwater drainage across the site.

   Structural
9. Drawing number WD 4.02B by Middap Ditchfield Pty Ltd dated July 2008 indicates that the
   proposed structure will bear load on the revetment wall located at the southern property
   boundary. It is relevant to note that structures should be designed and constructed such that
   they are free standing and are not connected to or imposing a load on the revetment wall. In
   this respect, please revise the proposed structure design to ensure that the revetment wall
   will not receive any load bearing during the construction or operational phase of the
   proposed development.

10. The existing sewer main traverses the northern portion of the site and the ‘zone of influence’
    (taken as the area within a 45-degree angle measured from the invert of the sewer main to
    the finished surface level) must be accurately located and determined by a licensed
    Surveyor and shown on all plans.

    To ensure Council’s sewer main is accessible for maintenance purposes and is protected
    from risk of damage no structures requiring a building permit (eg. buildings, swimming pools,
    retaining walls exceeding 1m in height, raised terraces, etc) shall be constructed within this
    ‘zone of influence’ or within 1.5m of the centreline of the sewer main, whichever is the
    greater. As such please amend all plans to ensure no structures requiring a building permit
    are located within the ‘zone of influence’.

    Setbacks

11. The Plans indicate a set of stairs located beyond the southern boundary (canal frontage).
    Please provide amended plans locating the stairs within the property boundary.

12. Deck 4 is approximately 1.8m above the revetment wall, and does not maintain the visual
    continuity and pattern of other structure heights above the revetment wall in Witta Circle. In
    this regard please amend plans indicating the deck level no more than 1m above the
    revetment wall.
