Ordinary Meeting <strong>of</strong> Council - 26 April 2005 1 / 13
1, 3, and 5 Lynbara Avenue and
12 Porters Lane, St Ives
Item 1 1219/04
1 April 2005
constructed across lot boundaries, the applicant will <strong>be</strong> required <strong>to</strong> consolidate all the lots prior <strong>to</strong>
issue <strong>of</strong> the Construction Certificate (Condition No. 86).
Traffic generation
The applicant has submitted a Traffic Report with the Development Application. The report is an
acceptable standard on which <strong>to</strong> base an assessment <strong>of</strong> the traffic related impacts <strong>of</strong> the
Development.
Based on the requirement <strong>of</strong> LEP 194, the proposal requires a minimum <strong>of</strong> 83 spaces which
includes 12 visi<strong>to</strong>r spaces. The proposal provides 83 spaces and complies with the LEP.
In terms <strong>of</strong> the impact <strong>of</strong> the development on the road network, this can <strong>be</strong> ascertained generally by
the capacity <strong>of</strong> the affected intersections <strong>to</strong> cater for the increased traffic loading. This is <strong>be</strong>st
determined by modeling the affected intersections at existing and post-developed use. The Traffic
Generation <strong>of</strong> this Development has <strong>be</strong>en estimated using the RTA “Guide <strong>to</strong> Traffic Generating
Developments” as follows:
Pre-Developed
Post-developed
No <strong>of</strong> dwellings 4 dwelling houses 4 x 1 <strong>be</strong>droom
24 x 2 <strong>be</strong>droom
21 x 3 <strong>be</strong>droom
Daily vehicle trips 36 (9 per dwelling) 217
Based (over conservatively) on
medium density:
4-5 per dwelling (2 or less
<strong>be</strong>drooms)
5 <strong>to</strong> 6.5 per dwelling ((3 or more
<strong>be</strong>drooms)
Peak hour vehicle trips 3.4 (0.85 per dwelling) 24.5 (0.5 per unit average)
The Stanley St/Lynbarra Ave street intersection has <strong>be</strong>en assessed with the INTANAL program by
the Applicants consulting Traffic Engineer (refer section 3.3 <strong>of</strong> DA submission Traffic Report). The
results show that the intersection operates currently at a ‘good’ level <strong>of</strong> service as defined by
INTANAL.
The assignment <strong>of</strong> an additional (net) 21 vehicles peak hour trips (see table above) in<strong>to</strong> this nearest
intersection is not expected <strong>to</strong> lower the operating level <strong>of</strong> service <strong>be</strong>low ‘good’ level <strong>of</strong> service. An
additional 21 trips over one peak hour is an average <strong>of</strong> one vehicle movement every 3 minutes over
the hour. It is noted that Mona Vale Rd is accessible via Lynbarra Ave and it is reasonable <strong>to</strong>
assume that the spread <strong>of</strong> peak vehicles may <strong>be</strong> heading <strong>to</strong> Mona Vale Rd via both Lynbarra Ave
and Stanley Street, or <strong>to</strong>wards <strong>to</strong> the city for example via Horace Street and Yarrabung Road <strong>to</strong> the
east. Traffic counts taken by the Applicants consulting engineer during am and pm peak times
indicate average acceptable delays in Stanley Street for vehicles <strong>to</strong> enter from the subject site.
