Ordinary Meeting <strong>of</strong> Council - 26 April 2005 21 / 24
26 <strong>to</strong> 30 Marian Street, Killara
Item 21
DA1243/04
18 April 2005
The assignment <strong>of</strong> an additional (net) 14 vehicles peak hour trips in and out combined (see
table above) in<strong>to</strong> the affected intersections (broken down in<strong>to</strong> 80% outgoing and 20%
incoming at am peak and the reverse at pm peak) is not expected <strong>to</strong> statistically lower the
operating levels <strong>of</strong> service at any nearby intersections.
The 18 trips over the respective peak hours (am and pm) generated by the subject
development (in and out combined) is an average <strong>of</strong> one vehicle movement over the proposed
driveway crossing every 3.4 minutes in the peak hour. This is not considered significant.
Accordingly, while the development may result in the surrounding road network <strong>be</strong>coming
marginally busier in terms <strong>of</strong> increased traffic movements, the subject development <strong>be</strong>ing
assessed is not expected <strong>to</strong> create additional traffic issues in the surrounding road network.
Construction Management
Based on the scale <strong>of</strong> works and expected construction vehicle movements, a detailed
construction traffic management plan must <strong>be</strong> submitted for review by Council Engineers
prior <strong>to</strong> the commencement <strong>of</strong> any works on site. This has <strong>be</strong>en conditioned.
Impacts on Council Infrastructure and associated works – comments
The scale <strong>of</strong> construction work for this site has potential <strong>to</strong> damage the frontage road reserve.
Accordingly, and for the amenity <strong>of</strong> the development, the following infrastructure works will
<strong>be</strong> required as part <strong>of</strong> the consent:
- Drainage works in Road Reserve, <strong>to</strong> Council specifications.
- Construction <strong>of</strong> a fully new concrete footpath over the full site frontage on Caithness
Street. To <strong>be</strong> designed and constructed in accordance with Councils Technical Services
specifications.
- New concrete driveway crossing <strong>to</strong> access the site from Caithness Street.
- Removal <strong>of</strong> all redundant driveway laybacks and re-instatement <strong>to</strong> upright kerb and
gutter.
- Replacement <strong>of</strong> the verge area <strong>to</strong> turfed verge <strong>be</strong>tween new footpath and existing kerb
alignment.
As with all development <strong>of</strong> this scale, there is the direct risk <strong>of</strong> damage <strong>to</strong> Council
infrastructure during the course <strong>of</strong> the works. A $50,000 bond <strong>to</strong> cover res<strong>to</strong>ration <strong>of</strong> such
damage (or completion <strong>of</strong> unsatisfac<strong>to</strong>ry works by Council) is <strong>to</strong> <strong>be</strong> applied.
