Traffic Engineering Letter · MCU24/0120

c. the assumed longitudinal grade of 0% - noting that SCG Consulting’s Site Survey &
Existing Services Plan (0336-OW1.1) dated Aug 2024 denotes an approximate
longitudinal grade of ~4.1% (negative) measured 30 metres upstream from the driveway
crossover.

Council does not believe the use of the ‘concealed driveway’ street sign is an appropriate
measure given the development is a full demolition and rebuild, and a more appropriate
driveway location exists.

Council is not satisfied that the proposed driveway crossover complies with Performance
Outcomes PO1 and PO2(a) of the Driveways and Parking Code. Inadequate detail has been
provided demonstrating the proposed driveway crossover is safe for its intended use and will
not cause adverse impacts on the safety of the road network. The location of the proposed
driveway crossover does not provide adequate Sight Distances as discussed above and in
Section 3.4 of Austroads’ AGTRD Part 4A.

Council’s preference remains for the driveway to be relocated to the eastern side of the
southern frontage.

Advice Required

1. Provide revised plans relocating the driveway crossover to the eastern side of the
southern frontage.

Issue — Plot Ratio

e The information request response does not detail any design changes to demonstrate
the exclusion of the areas identified on the lower level as per the information request
(see below (re-highlighted in green)).

e The gross floor area calculations do not align with architectural plan dimensions for the
laundry, this is noting that the GFA exemption refers to areas for parking, loading or
manoeuvring not storage areas.

 

Advice Required

2. Include the above-mentioned areas in plot ratio calculations and amend the design as
necessary to achieve a compliant plot ratio.

3. RESPONSE TO FURTHER ADVICE

As the decision for the development application is due 17 December 2024.
