MCU16-0099 & OPW16-0218 - Proposed nbn Facility at 23 Jirrima Cres Cooroibah - Response to Information Request

        (a)      The ability of the use to function effectively during and immediately after a flood event; and
        (b)      The potential of fill to improve flood resilience of any ancillary infrastructure sited at ground
                 level; ideally elevating structures above the nominated flood level (derived from a Council
                 issued Flood Certificate).

Response

Please refer to Attachment B for a Council issued Flood Certificate for the subject site.

The Flood Certificate illustrates that the flood level on the subject site for a Q100 event is 4.7 m AHD. The
level of the proposed compound location is 5 m AHD. Nonetheless, the associated equipment cabinets will
be located on an elevated platform, on a standard plinth of 300 mm, and are therefore situated at an
appropriate level to adequately accommodate the proposed use and mitigate the risk of inundation to the
proposed facility. The elevated platform has been illustrated within the Amended Proposal Plans within
Attachment A.

The proposed development is therefore compliant with O18 of the Natural Hazards Overlay Code, which
states:

        “All lots have sufficient area that is above the define flood event flood level or where modelling is
        not available, the highest recorded flood level, to safely and adequately accommodate the intended
        use.”

Visual Amenity

The Specific Outcome O39 of the Infrastructure Uses Code requires the proposed monopole to be visually
integrated with its landscape so as not to be visually dominant or obtrusive.

Information Required

3       Please provide a photomontage of the proposed monopole. The montage shall superimpose the
        proposed pole’s height and bulk onto images taken from the following locations:
        (a)      The existing house at 25 Jirrima Crescent (Lot 2 on RP212300). The photo should be taken
                 from the open space area south of the existing large shed looking towards the tower (Refer
                 to Figure 1).
        (b)      The existing house at 21 Jirrima Crescent (Lot 46 on RP136461). The photo should be
                 taken within the pool area north of the dwelling, looking towards the tower.
        (c)      The existing house at 19 Jirrima Crescent (Lot 45 on RP136461). The photo should be
                 taken from the lawn area directly to the west of the dwelling, looking towards the tower.
        (d)      From the Lancaster Lane reserve fronting the existing dwelling at 70 Lancaster Lane (Lot
                 54 on SP208642), looking towards the tower.

Response

As requested by Council, a total of four (4) photomontages have been produced, and are discussed in detail
below.

Photomontage 1 illustrates a view of the proposed facility from the front of the existing house at 25 Jirrima
Crescent (Lot 2 on RP212300). It should be noted that the residence was door-knocked on Wednesday 21
