Item 6
Amend the pathway width on the western side of Road C to be in accordance with Condition 17

Response
Please refer to Drawings 1856 R36 & R39 which demonstrates this footpath width is compliant
with Condition 17. The 3m footpath width is proposed to be initiated at the pedestrian crossing
location to the eastern side of Road C as this ensures suitable verge width for Stormwater Quality
Treatment devices and drainage structures in the verge and provides a clear transition point from
a 2m wide footpath to 3m wide.


Item 7
Road C is proposed with a 15m carriageway, compared with the 12m width required in Condition
17. Clarify how the proposed wider width is proposed to be used and operated.

Response
Please refer to Drawing 1856-R52 with additional information to confirm the design road reserve
widths and pavement widths are compliant with Condition 17. The 15m carriageway (measured
between kerb inverts or nominal face of kerbs) is inclusive of the 1.5m cycle lanes on each side
of the 12m carriageway width.


Item 8
Indicate on the relevant plans the pathway as described in Condition 24(d)

Response
Please refer to Drawing 1856-R37 demonstrating the proposed pedestrian pathway network
configuration in front of Covenant J. The north verge of the Hofmann Drive road extension is
proposed to contain a Stormwater Quality Improvement Device (SQID) here as this is the low
point in the road catchment. Incorporating a pedestrian pathway along this frontage when there
is already a pathway on the southern verge will compromise the ability to effectively locate a
bioretention basin here without imposing on the existing boundary of Covenant J. It is understood
that provision for a pedestrian connection to the frontage of proposed Lots 17-21 will be applied
as conditions of future development for these lots. In order to provide a pedestrian connection to
the network here, it is proposed that the pathway network divert all foot traffic to the southern
verge where adjacent to the bioretention basin and then return it to the northern verge to provide
future pedestrian connection along the frontage of Lots 17-21. Therefore, the pedestrian network
connectivity is maintained, and suitable spatial provision is made for the SQID which is essential
to clean stormwater discharge from the subdivision road network.


Item 9
The proposed level of the roundabout at the Road B / Hofmann Dr intersection appears to be too
high and creates possibly unnecessarily steep grades into Road B and Hofmann Dr from the
roundabout. Provide an amended design that lowers the roundabout to improve these grades, or
alternatively provide justification for the proposed design

Response
Please refer to Drawings 1856 R36, R45 and R48 with amended longitudinal grades for the
approach and departure for Hofmann Drive and Road B with the proposed southern roundabout.
These grades have been reduced to 6% in accordance with Austroads requirements. Please note
the southern roundabout is at a predetermined level to ensure that the existing topographical site
catchments are generally maintained. Road A, which grades out to the existing roundabout on
Walter Hay Drive, has a very shallow gradient of 0.5%. If the roundabout surface levels were
reduced, this would divert the eastern site catchment back towards Covenant J and the Hofmann
Drive drainage reserve.
