Golf Course Requirement (1998) vs. School Camp Requirement
The Approval for the Golf Course development was not reviewed at the time of preparing the Traffic Report (BMC 2023)
for the Group Stay Accommodation. Following consideration the Golf Course Conditions for a 6.0m pavement in Kabi
Road, the recommendation of the Traffic Report for a 6.2m pavement width, as per current AUSTROADS requirements,
has been revisited.

The change between road upgrade requirements for the Golf Course and Group Accommodation represents an
additional 0.2m road width along the length of Kabi Road. The addition of 0.2m pavement width, or 0.1m per lane, is
expected to have a minimal impact on the safety and operation of the roadway.

It is my opinion that a requirement to upgrade some 620m length of pavement, for a 0.2m lane width, is not justified
when considering the cost vs benefit. Simply put, the benefit of the minimal road widening does not justify the cost, nor
the interruption to Kabi Road as a result of construction works.

In addition, please see the below in relation to the traffic implications of the Approved development intensity for the
Group Accommodation.

School Camp Requirement: Revised Development Intensity
At Section 5.4 of BMC (2023), the following was noted in relation to the Kabi Road upgrade recommendations:

         “Alternately, it would be possible to limit the operations of the proposed facility to reasonably expect less than
         150vpd on Kabi Road for the peak-repeatable event. This could be facilitated by limiting group sizes outside of
         school camp operations. This would enable the existing carriageway of Kabi Road to accommodate the
         proposed site operations. It is, however, understood that this is not an option which the proposed site operator
         wishes to explore at this time.”

It is important to firstly note the BMC (2023) report assumptions and recommendations were based on a total of
299 beds within the Group Accommodation. The revised Approval includes 88 beds, including allowance for 8 staff.

The following are noted in relation to the likely traffic volumes on Kabi Road as a result of the revised Group
Accommodation use, as permitted by the Approval:

        A peak repeatable event is typically considered to be represented by the 85th percentile, that is, an event that
         is not exceeded 85% of the time. Applicable to a daily traffic volume, this would be a volume not exceeded on
         54 days of the year (events).
        Table 5 of BMC (2023) identified that if the 85th percentile daily traffic volume on Kabi Road is between
         1 -150 vehicle per day, AUSTROADS Part 3 would support the current carriageway width as being appropriate.
        Base Case traffic volumes recorded and set out in Table 3 of the BMC (2023) traffic report are reproduced
         below:




        The traffic volumes anticipated in BMC(2023) for the Group Stay operations have been revised (overleaf) to
         reflect a change to 88 beds / 10 camp staff.
