Sight Visibility to the North of proposed intersection shown below




Preliminary design drawings have been prepared showing the new road and intersection. As there
is no truncation on the boundary of the property to the north of the new street the verge width may
not fully comply with Council’s design standards however there will be sufficient space to
accommodate the footpath and ramps to tie into the existing footpath on Pavilion Street.

The swept path for a waste collection vehicle as also be added to the preliminary drawings to
demonstrate there is sufficient room for the WCV to turn around in the proposed turning head
space. Note a NSC standard 10.2 WCV turning path has been used for this purpose.



    4. Stormwater Management/Bio-Retention Basin
Preliminary Drawings have been prepared for the proposed bio-retention basin. The size of the
basin is based on parameters contain in the Stormwater Management Plan prepared by Peak
Urban. Our plans demonstrate that the required bio basin filter area (80m2) and storage volume
can be provided with the allocated space in the plan of development. Please note that we have
generally adopted 1 in 4 batters throughout except for a 1 in 2 batter on the northern side of the
basin. There should be no need for any retaining walls in the bio basin. The outlet from the basin
is directed to the west towards to creek, discharging into the balance area of lot 10.
