6          Assessment of Site Layout
6.1        Car Parking
The main (formal) car parking at the front of the site is existing.
The new car parking areas are informal, with the parking areas shown as 5.5m long and 2.5m wide
(minimum), which meets the requirements of the Australian Standard for Off Street Car Parking for low
turnover parking.

6.2        Gradients
Information is to be provided and reviewed by the Civil Engineer in relation to gradients on the proposed
internal roads and their suitability.

6.3        Servicing and Bus Accessibility
The subject site requires access by buses / coaches and delivery vehicles.
The accessibility of the site by the required design vehicles, specifically a 12.5m coach (as per AUSTROADS)
and 14.5m coach (as per AUSTROADS) have been considered in the design. The design has been informed
by the results of swept path assessments.
Graphical outputs of the swept path assessments, undertaken utilising the computer program AutoTRACK,
are reproduced at Appendix E to this advice. The swept path assessments, which have now been updated
on the a feature and level survey base at the Kabi Road / Cootharaba Road intersection, demonstrate:
        Buses can enter and exit the site in a forward gear.
        Buses can access the loop road for each Village for pick up and drop off, travelling in a clockwise
         direction.
        A 12.5m Heavy Rigid Vehicle (HRV) can rear load in the loading area provided adjacent to the
         “Communal Area”.
For access to/from Kabi Road at Cootharaba Road, accessing to/from the south, utilising the existing
intersection form, the following are noted:
        A 14.5m long coach can enter its the wheels well contained within the roadway, with a minor
         encroachment over the Kabi Road centre line on entry. This is acceptable on the basis of:
             - low traffic volumes,
             - the likelihood that left turning vehicle out of Kabi Road will be positioned further to the
                south of the centre line; and
             - the entering coach can wait for the roadway to be clear prior to entering, recognising low
                traffic volumes.
