                                                                            Parking & Traffic Impact Assessment Report




5             Impact Assessment
5.1           Road Network Capacity
An additional 8 trips to the eastbound traffic volume on Doonella Street is less than 1% of the existing
background traffic during the AM peak hour. It is assumed the PM peak hour would be similar, but a reverse
flow (tidal). The PM impacts would be of a similar scale.
Likewise, for the intersection approaches, assuming that the majority of the traffic observed mid-block on
Doonella Street is through traffic (west to east), then the approaches to the roundabouts would have similar
volumes as mid-block.
The development traffic as a percentage of existing traffic is illustrated on the diagram below.
