Amended Stormwater Management Plan - Revision B 10.3.21

SUMMARY


The following Site Based Stormwater Management Plan addresses the stormwater drainage
issues associated with the development of Lot 1 on RP 226728 known as 32 Viewland Drive,
Noosa Heads

The proposed development is summarized as an SDA Accommodation Development for
Youngcare.

The site falls approximately 7.5% to the south west corner. From an environmental perspective,
there are no clear environmental values associated with the site as there are no waterways and
vegetation is non-remnant. The site measures 3105m2. The existing stormwater drainage will
be improved on by the stormwater management proposed herein.

Erosion control measures will comply with best management practices.

There will be an increase in impervious surface area due to the development but the increase in
peak flow and runoff volume are mitigated by a stormwater management strategy that reduces
the impact compared with existing drainage conditions.

Achieving the water quality objectives is an important aspect of the proposal.

The design is based on design standards as described in “State Planning Policy 4/10 Healthy
Waters” and “Queensland Urban Drainage Manual” which in turn references “Water Sensitive
Urban Design for South East Queensland”.
