Ordinary Meeting <strong>of</strong> Council - 26 April 2005 6 / 3
Item 6
S03730
12 April 2005
The environmental capacity for peak hourly volumes per lane should not exceed 1000 vehicles per
hour <strong>to</strong> avoid excessive traffic delays. This needs <strong>to</strong> <strong>be</strong> considered in association with the
performance <strong>of</strong> the intersections in terms <strong>of</strong> the Level <strong>of</strong> Service. The levels <strong>of</strong> service for the
various signalised intersections around the site are as shown:
Intersection
Mona Vale Road/Memorial Avenue
Link Road/ Memorial Avenue

Mona Vale Road/Stanley Street
Level <strong>of</strong> Service

COMMENTS
Whilst traffic access is one important aspect, consideration also needs <strong>to</strong> <strong>be</strong> given <strong>to</strong> property
ownership and the processes associated with the possible creation and closure <strong>of</strong> roads.
New internal roads can <strong>be</strong> created by either developer agreement or planning powers such as
consent conditions. If it can <strong>be</strong> established that the road could provide <strong>be</strong>nefit <strong>to</strong> all parties by
providing access <strong>to</strong> existing roads and determined <strong>to</strong> <strong>be</strong> the most efficient access, then the road
could <strong>be</strong> dedicated <strong>to</strong> Council. Alternatively, if the proposed developer is not in favour <strong>of</strong>
dedication <strong>of</strong> a new road, then Council may need <strong>to</strong> proceed with acquisition and creation.
Attached, as Attachment A, is a copy <strong>of</strong> an internal traffic report on the likely traffic generation
from redevelopment <strong>of</strong> the area under LEP 194. As can <strong>be</strong> seen in the report, the likely peak hourly
traffic generation would <strong>be</strong> around 250 vehicles per hour. If this traffic were <strong>to</strong> access Memorial
Avenue then it would place added pressure on the intersection <strong>of</strong> Memorial Avenue and Mona Vale
Road. Consequently, some measures may <strong>be</strong> required <strong>to</strong> improve the capacity <strong>of</strong> this intersection.
If the traffic access were <strong>to</strong> <strong>be</strong> directed in and out <strong>of</strong> Stanley Street, this would impact on Mona
Vale Road <strong>be</strong>cause an additional phase would need <strong>to</strong> <strong>be</strong> included at this intersection. Hence, it
would need <strong>to</strong> <strong>be</strong> demonstrated <strong>to</strong> the Roads and Traffic Authority, that the flow on Mona Vale
Road would not <strong>be</strong> adversely affected.
