Attachment 5 - Stormwater Managment Plan · 132007.12.8

1 Introduction
AquaIntel has been commissioned by N.C. Oliver Properties Pty Ltd to prepare a
Stormwater Management Plan to support the Material Change of Use application for
a proposed carpark at Lot 4 Goodchap Street, Noosaville (Lot 3 SP264909).
The proposed outcome of this document is to identify stormwater management
options to comply with the Division 20 – Water Sensitive Urban Design Code and
Division 18—Transport, Roads and Drainage Code of the Noosa Shire Council’s (NSC)
“The Noosa Plan”. From this, the load based Water Quality Objectives (WQO’s)
stipulated in the State Planning Policy – July 2014 (DSDIP) for the South-East
Queensland region will be adopted for the site. The purpose of this SMP is to identify
the final stormwater management options to be implemented within the site to
achieve elements of the code. The objectives of this SMP are to:
   •   Ensure the proposed development maintains or improves the environmental
       values of the receiving waters within the receiving catchment throughout the
       operational phase;
   •   Consider suitable Stormwater Quality Improvement Devices (SQID’s) based on
       Water Sensitive Urban Design (WSUD) principles;
   •   Recommend an appropriate stormwater treatment strategy for the proposed
       development that complies with Noosa Shire Council (NSC) water quality
       objectives;
   •   Ensure the development achieves non-worsening of stormwater flows
       downstream of the site.

1.1 Site Characteristics
The location of the proposed development site is shown in Figure 1 and covers an area
of approximately 0.20ha. The site is bounded by an existing Telstra site to the north,
Central Queensland University medical hub to the east, bushland park to the south
and private property to the west.
The site currently has an unsealed carpark that services the adjoining Central
Queensland University medical hub. The site falls from the north-east to south-west
boundary where runoff flows into bushland park. The site is part of the Noosa River
catchment and is not subject to regional flooding. Elevations on the site range from
4.5m to 7.8m AHD.
The proposed development layout is provided in Appendix 1.
