Response to Information Request OPW20-0145. 19.10.2020 · OPW20/0145

16. Provide a specific assessment by an RPEQ of the position of the emergency access location for lot 23. The
assessment must ensure that the most appropriate location is adopted taking account of sight lines along
both Walter Hay Drive carriageways as well as inherent bushfire emergency access requirements. The
access must be located to achieve the most appropriate balance of having adequate sight lines onto Walter
Hay Drive while also satisfying bushfire requirements (being to have the access near the western end of lot
23).

Stockwell Response

The sight lines for the emergency access egress from Lot 23 is in accordance with the Austroads Table 3.6.
Based on a 60km/hr approach speed, the minimum sight distance required is 67m. As seen in Figure 1 below, A
sight distance of 70m is achieved.

17. Indicate on the relevant plans where on-street parking is proposed to be prohibited.

Stockwell Response

Please refer to Barlow Shelley's Line Marking Layout Plan on drawings 1856 R65. Parking is prohibited on the
northern side of Road B and is indicated by yellow line marking as indicated on drawings R65-B.

18. Council has some concerns with the proposed horizontal alignment of the Hofmann Dr extension and Road
C, particularly the reverse curves on both roads and the small radius curve in Road C. Provide assessment,
prepared by an RPEQ, of the proposed horizontal alignment of Hofmann Dr and Road C against the
requirements of Council’s Engineering Design Standards.

Stockwell Response

The straight tangent points between the same direction corners in Hofmann and Road C have been removed.
Reverse curves will still be necessary because of either alignment into a roundabout (road to southern roundabout)
or due to existing boundary lines (for Covenant J) and the current construction of the road pavement. It is proposed
these reverse curves remain in the design. Please refer to Drawings 1856 R36, R37, R48 and R51 which show the
amended road alignment.
