that addresses water quality, will be developed following the geotechnical investigation as geological
and groundwater features are confirmed. Council will have the opportunity to review these at the
Operational Works stage of the development.

        Issue – Access
        There is insufficient information on the internal driveway and to demonstrate how the
        internal driveway will function when a vehicle is entering and another is existing the internal
        driveway.

        Information Required

        8. Provide additional detail on the proposed driveway and access. The detail must be
           prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of
           Queensland) and include, but not be limited to:
           a. levels and grade of the access driveway;
           b. a longitudinal section extending from the centre of the formation along Mill Street
              to the beginning of the downward slope of the basement ramp; and
           c. c. demonstrate that a B99 vehicle will not scrape or bottom out while entering or
              exiting the access driveway.
           d. d. demonstrates how the internal driveway will function in the event a B99 vehicle
              is entering while another is exiting


The engineering drawings previously submitted included layout plans with design surface levels and
contours, as well as a driveway long section for the basement ramp to demonstrate satisfactory
vertical clearance. A low clearance B85 vehicle model was used for the vertical clearance
assessment and due to the limited width available with the narrow lot configuration. The amended
engineering drawings now show an extended long section and additional turn paths for a B99
vehicle. A B99 can be accommodated in the basement parking spaces as shown, noting that there is
space for 2 larger cars in the front area east of the ramp. A ground conflict report is also now
included, demonstrating that a low clearance B85 vehicle maintains at least 100mm ground
clearance whilst traversing the grade change sections at the top of the ramp, and 80mm clearance at
the transitions at the bottom of the ramp. The proposal is in accordance with AS2890.1 Section 2.6
and Appendix B for a residential development.

The amended engineering drawings now include additional information to demonstrate that there
are passing opportunities within the existing and proposed driveway geometry. The existing
easement driveway section is wide enough (5.5m) to allow for 2 B99 vehicles to pass. There is also
sufficient space for a vehicle to wait in the front area to the east of the ramp whilst another vehicle
is using the ramp access. A conflict between a vehicle entering and exiting is not expected to occur
frequently.
