                               Demand Rate during    1.184 spaces per 100m2 GFA                       32 spaces
                               Peak Demand Period
                               (Weekends)
                                                     Office
                                                     1 space per 40m2 GFA                             33 spaces
                                                                                           Total     65 spaces


The provision of 95 spaces exceeds the average rates outlined in Table 2 and importantly aligns with the
practical parking demand exhibited during the peak demand periods. Based on the above assessment, the
provision of 95 spaces is considered acceptable.

TTM Response – Item 8) Main Access Aisle Width
As per the amended development plans included as Attachment 1, the parking aisle has been widened to
6.5m as requested.

TTM Response – Item 9) Access Configuration
A signs and line marking plan has been included as TTM Drawing 21BRT0259-3 in Attachment 2 which
demonstrates safe and efficient operation of the intersection for both service and customer vehicles.

A give way sign and line marking will be constructed on the western leg of the intersection, while egress
from the eastern leg of the intersection will be restricted to left turn only. A stop sign and line marking will
be constructed on the northern leg of the intersection. As the northern leg operates as one-way exit only, a
no entry sign will be constructed on the opposite side of the stop sign to ensure vehicles do not enter the
northern leg. The continuity lines aim to facilitate the southern and eastern legs of the intersection
effectively as a two-way road with the northern and western legs operating as intersecting roads. The signs
and line marking plan will manage the priority of the multitude of traffic movements as follows.

    -   All movements from the southern leg will have the highest priority.
    -   Left turning movements from the eastern leg will have right of way over all movements
    -   Through movements from the northern leg will give way to right turning and through movements
        from the western leg.
    -   Right turning movements from the western leg give way to the through movements between the
        southern and eastern approach.

It should be noted that the proposed line marking allows for movements from the south to have free left and
right turns. If thoroughfare and respective line marking was provided to the existing carpark to the west,
vehicles entering the development would be required to stop.

The proposed site access configuration and operation is considered safe and efficient in accommodating the
multitude of traffic.
