1856 - Partial Response to Information Request - Barlow Shelley OPW20-0145 · OPW20/0145

Item 15
Provide amended plans that indicate lockable gates to prevent regular use of the emergency
access for Lot 23, both on the driveway and on the central median crossing, together with
appropriate signage.

Response
Please refer to Drawing 1856-R40 demonstrating the emergency gate position and type. It is not
proposed to include any gate device in the central median breakthrough in Walter Hay Drive as
this is another access device that would need to be operated in an emergency, thereby slowing
down egress. The breakout in the central median island is proposed at only 6.2m wide to prevent
regular vehicles having sufficient space to use the breakout for U-turns.


Item 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).

Response
Please refer to Drawing 1856-R41 demonstrating the emergency egress location from Lot 23
including sight lines. Condition 8.1 of the court ordered approval requires the egress point to be
located in the north western section of the Lot 23 frontage.
Austroads Table 3.5 for crossing requires a 4 second critical acceptance gap (tc). From Table
3.6, the minimum sight distance should be 67m based on a 60km/hr approach speed or 89m
based on an 80km/hr approach speed. There is a high likelihood that the vehicle speed approach
will be significantly reduced in an emergency event where the gate is intended for use. Therefore,
the sight distance requirement based on the posted speed on 60 km/hr is deemed appropriate.
The below aerial screenshot verifies the sight distance shown on plans as approximately 70m
due to vegetation.
