Appendix 3 - Traffic Engineering & Parking Report (00012497)

Compliance with Australian Standards AS2890.1
The parking arrangements have also been assessed against AS2890.1:2004. Parking
spaces within the basement car park are indicated on the layout provided by Inter. All
residential car parking spaces have a minimum length of 5.4m and a minimum width
of 2.4m. Aisle widths are a minimum width of 6.2m wide. The visitor parking spaces
are 2.4m wide and a wide aisle of 7.5m has been provided. The parking spaces and
aisle dimensions generally comply with the requirements of AS2890.1 for 90 degree
User Class 1A and User Class 3 parking.

Parking spaces within the basement will be allocated specifically to residential
apartments therefore search patterns and circulation will be simplified. The ends of
the aisles are extended 1m beyond the last parking space to accommodate manoeuvres
as per Clause 2.4.2 (c) of AS2890.1. An additional 300mm has been provided to car
parking space widths for those spaces located adjacent to walls. The parking spaces
comply with AS2890.1:2004 Figure 5.2 ensuring all walls and obstruction are clear of
the design envelope around parked vehicles.

Clause 2.5.3 of AS2890.1 provides requirements for circulation roadway and ramp
grades. The proposed ramp into the basement has a grade of 1:6 for 7.52m with 2m
long grade transitions of 1:20 at either end of the ramp, complying with requirements.
A security gate at the bottom of the basement ramp will restrict access to residents
only. The security gate will be controlled via remote control, and therefore vehicles
will not be required to stop on the ramp. The minimum width for circulation roadways
and ramps for two way traffic is 5.5m (with an additional allowance of 300mm if
adjacent to a wall greater than 150mm high). The proposal meets the minimum
roadway width requirements of 6.0m for the two-way access ramp the basement
parking area.

Clause 3.3 of AS2890.1 includes requirements for gradients of access driveways. The
grade for the access driveway from the road frontage (kerb) to the property boundary
is a maximum of 1 in 20 (5%). The proposed access meets the requirements for access
driveways.

Minimum queuing length is 12m (2 car lengths) from the property boundary into the
site as indicated in Clause 3.4 of AS2890.1. The available queue length is 13m from
kerb with clear sight visibility along the access into the site. Whilst the traffic
generation from the proposed development is low and will operate under free flow
conditions, a give way control point will be line marked to give priority to vehicles
entering the site over those exiting.

Clause 3.2 of AS2890.1 includes requirements for access driveway widths, with a
recommended minimum width of 5.5m. The proposed access driveway is 5.5m wide,
complying with current requirements. The driveway must meet the requirements
of standard drawing RS-049 and RS-059 for residential driveways.

The headroom clearance in the basement and also for the ground level overhang is at
least 2.2m which complies with the minimum requirement of 2.2m as outlined in
Clause 5.3.1 of AS2890.1.
