Is the proposed car stacker an acceptable means of parking provision?
- Council argues that the development application should be refused because the proposed design of the car park, and the use of the mechanical car stacker, is unacceptable. The expert evidence in the proceedings focussed on compliance of the mechanical car stacker with the relevant Australian Standard, and the resulting restriction on the size and height of vehicles that can be accommodated within the facility.
- In support of the original development application, Varga Traffic Planning prepared a Traffic and Parking Assessment report (Exhibit 1). The report concludes that, in applying the relevant controls in DCP 2012, the commercial component of the development requires the provision of 1.4 (rounded to 1) spaces for the tenancy, 1 visitor and a courier space. In the absence of specific of street parking rates in DCP 2012, the report adopts the rates required in State Environmental Planning Policy (Affordable Rental Housing) 2009 of 0.2 spaces/ room as an indicative parking requirement. As the amended plans have a total of 42 boarding rooms, it is the applicants submission that the generation for the boarding house component is 8.2 spaces (rounded to 8), plus an additional space for the site manager. Applying the requirement in the DCP at 6.8.2 to round down, this generates a demand of 12 of which the development proposes 13 spaces. In addition, the development proposes nine bicycle and nine motorbike spaces within the basement as required by DCP 2012.
- Relevantly the Australian New Zealand Standard AS 2890.1: Parking facilities (the parking standard) provides the following definitions at 1.3:
1.3.6 B85 Vehicle
The design motor car whose physical dimensions represent the 85th percentile class of all cars and light vans on the road
1.3.7 B99 Vehicle
The design motor car whose physical dimensions represent the 99.8th percentile class of all cars and light vans on the road
By reference to Appendix A of the parking standard, these vehicles have the following design dimensions:
B 85: 4910 (l) x 1870 (w) mm overall
B 99: 5200 (l) x 1940 (w) mm overall
- It is agreed between the experts that the proposed car stacker is not capable of accommodating the maximum vehicle length of the B99 vehicle, as provided for in the parking standard. The experts agree that the proposed WOHR Combilift 543 car stacker in the "premium model" has an overhead clearance of 2.1m, achieving the height requirement for the B99 vehicle. It is the evidence of Mr Varga that the development has been designed to accommodate this model of car stacker.
- The issue in contention in relation to compliance with height is therefore resolved if the development incorporates the WOHR Combilift 543 car stacker in the "premium model", which accommodates both the B85 and B99 vehicle. The outstanding issues in contention remains the compliance of the car stacker with the parking standard as it relates to width and length of parking spaces.
- The experts agree that the relevant section of the parking standard is 2.4.1 (a) which states the nominal length of a parking space in a parking module shall be 5.4m. I note that the parking standard provides exceptions to the length where the end overhang of the vehicle can be accommodated (e.g. at a kerb) or where it is designated as a small space.
- It is the evidence of Mr Hind that the length of some common vehicle types exceed 5m. His evidence is that these vehicles include:
VX -VY Holden Commodore Wagon: 5046mm
EL - BF Ford Falcon Wagon: 5053 -5077mm
However, he is satisfied that the vehicle stacker, as proposed, can accommodate the B85 vehicle and its associated swept paths. It is his evidence that the car stacker, to be compliant with the parking standard, should accommodate up B 99 vehicle.
- In contrast Mr Varga argues that the car stacker, at 5m length, can accommodate 85% (B85) of vehicles as well as the following 4WD/SUV models:
Toyota Land cruiser: 4990mm
Toyota Prado: 4930mm
Mercedes ML: 4804mm
BMW X5: 4880mm
Jeep Grand Cherokee: 4623mm
It was Mr Varga's oral evidence that the B99 vehicles tend to be luxury cars, and in his view, it is unlikely this development would generate demand for this size vehicle.
- In relation to compliance of the car stacker with the parking standard requirement for width, the proposed car stacker has an up-stand of approximately 195mm between the spaces as part of the platform design. During the oral evidence of the experts, they addressed the requirement, under section 2.4.1 (b) (ii) of the parking standard, to include an additional 300mm to the required space width to accommodate any obstruction adjacent the parking space. It is the evidence of Mr Hind that if applied to the current proposal the need to accommodate the up stand obstruction would result in a total width of 2700mm (2400 +300) for clear access on one side, and 3000mm for clear access on both sides.
- It was Mr Varga's evidence that the maximum width of the platform for the WOHR Combilift 543 in the "premium model" is 2700mm. If this size were implemented in the project, the number of car spaces provided would be less as the proposal currently accommodates a narrower model with a platform width of only 2500mm. This would reduce the parking provision to two bays. However it was his evidence that this increased width is unnecessary for the following reasons:
1. The proposed car stacker model gives a clear platform width of 2500mm. The B85 vehicle width is 1870mm, and the B99 1940mm, which in his view provides for adequate access;
2. The up-stand of 195mm in height is less that the height of the bottom of the door of common vehicles (Corolla: bottom of door 285mm, Commodore: 290mm) and thus in practice would not provide an obstruction.
3. The proposed car stacker has been successfully installed in a number of other developments (detailed in the expert report).
That technical information appended to the expert report indicates "the premium model" comes in the following platform widths: 2500, 2600, and 2700mm.
- Mr Seton argues that the development as proposed does not comply with cl. 6.85 Relevant Standards of DCP 2012 as the parking provided is not in compliance with the parking standard. It is his submission that if compliance with the parking standard was to be achieved through the deletion of the car stacker it would reduce the parking provision in the development to a total of seven spaces.
