                               Further, the adjoining properties (for example #15 to #23 inclusive) and adjacent
                               properties (for example #24) all provide 1.8 metre high solid walls/fences along the
                               front boundary. Overall, this outcome is common for properties along Coral Tree
                               Avenue generally. As such, the proposed front fencing outcome is compatible with
                               the existing streetscape character, and if anything creates an improved outcome for
                               the surrounding area. Therefore, the proposed front fence will not unduly impact on
                               the streetscape character of Coral Tree Avenue.

                               Casual Surveillance

                               Council’s claim that the proposed front fencing will unduly impact on the streetscape
                               character of Coral Tree Avenue is unfounded and indicates that the existing situation

Information Required
19. Provide additional detail on the access driveway and the manoeuvring area.
    The detail must be prepared by a suitably qualified person (RPEQ – Registered
    Professional Engineer of Queensland) and include, but not be limited to:
    a. a design generally in accordance with RS-049, RS-050 and any associated
        addendum;
    b. a longitudinal section extending from the centreline of the formation in
        Coral Tree Avenue to driveway adjacent to the garages; and
    c. demonstrate that a B99 vehicle will not bottom out of scrape while
        entering/exiting the driveway.
20. Provide a Turning Path Plan that demonstrates how the driveway and
    manoeuvring area will function. The plan must be prepared by a suitably
    qualified person (RPEQ – Registered Professional Engineer of Queensland) and
    include, but not be limited to:
    a. demonstrate how a B99 vehicle, beginning and ending at the proposed
        ‘refuse area’, can enter and exit each garage while the proposed visitor
        carpark is occupied; and
    b. demonstrate how a B99 vehicle can enter and exit the visitor carpark while
        both garages are occupied.
21. Provide comment from a suitably qualified person discussing what necessary
    safety controls are to be implemented to ensure the sight lines from the road
    frontage to the manoeuvring area remain unobstructed and to remove the
    potential creation of traffic hazards between vehicles entering and exiting the
    site simultaneously.

The submitted documentation indicate that the proposed works is to be constructed
in close proximity (above and adjacent) to existing Unitywater infrastructure and no
relocation point to the existing water meter has been proposed. A statement from
Unitywater approving the locality of the proposed works to their existing
infrastructure has not been provided.

Information Required
Provide an additional statement from a Unitywater representative authorising the
locality of these works and the relocation of the water meter
23. Lawful point of discharge                                                           Refer to the Engineer’s response letter in Attachment 3.
According to Council standards, the maximum discharge flow rate to a Lawful Point
of Discharge is 25l/s in a 1% AEP event. The submitted documentation indicates that
the maximum site discharge to each kerb adapter is 14l/s in a 5% AEP event. Council
are concerned that the discharge flows from each kerb adapter in a 1% AEP event
may create a worsening of existing drainage conditions and potential traffic hazards.

Information Required
Provide additional detail considering the discharge rate in a 1% AEP event and
demonstrating that this discharge rate will not create a worsening of conditions or
potential creation of traffic hazards along Coral Tree Avenue if a 1% AEP event
occurred. This detail must be prepared by a suitably qualified person (RPEQ –
Registered Professional Engineer of Queensland).

   b. be a minimum of 45 Litres;
   c. be maintained (watered) for 12 months; and
   d. be planted according to the standard species and setbacks. A few
