RFI - stormwater report

1 Introduction
AquaIntel Pty Ltd was commissioned by Tod Consulting Pty Ltd to prepare a Stormwater
Management Plan to support the Reconfiguration of Lot Approval for proposed
residential use (10 Lots) at 30 Pottery Street, Pomona (Lot 496 MCH 591).
The proposed outcome of this document is to identify stormwater management options
that could be implemented within the development in order to achieve the
requirements and targets of Noosa Shire Council Planning Scheme “Drainage Code”
(NSC, 2018a), “Flood Hazards Overlay Code” (NSC, 2018b) as well as the relevant
provisions of State Planning Policy – Appendix 2. The intent of the codes associated with
these documents will be achieved through the appropriate integration of stormwater
management options within the proposed residential land-use. 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) and State Planning
       Policy water quality objectives;
   •   Ensure the development does not result in nuisance flooding from stormwater
       flows downstream of the site; and
   •   Ensure the site complies with the lawful point of discharge.


1.1 Site Characteristics
The location of the proposed development site is shown in Figure 1-1 and covers an area
of approximately 1.256ha. The site fronts Pottery Street and is bounded by private
properties to the north, south and west.
The site is formed by a ridge to the north and falls south to the adjoining properties and
Pottery Street to the east. The site is unaffected by regional flooding or overland flow,
refer to Council’s regional flood mapping in Figure 1-2.

The proposed development layout is provided in Appendix 1.
