Request to Amend Application and Response to DSDIP's Information Request · MCU14/0009

1 Introduction
AquaIntel has been commissioned by TOD Consulting on behalf of K and C Rolton to
prepare a Stormwater Management Plan (SMP) in response to Council’s Information
Request (Ref: MCU14/0009 dated 27 February 2014) in order to support their
Material Change of Use (MCU) Application for a light industry / commercial
development on the existing site at 1 Factory Street, Pomona (Lot 20 SP194118).
The development will be required 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 4/10 - Healthy
Waterways and Urban Stormwater Quality Planning Guidelines 2010 (DERM, 2010)
for the South East Queensland region will be adopted for the site. The purpose of
this SMP is to identify the stormwater quality 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. The site grades
from the north to the south and connects into a stormwater pit constructed in
Factory Street road reserve at the site frontage. Site elevations range from 86.7 to
86.3 m AHD.
There are no major external catchments influencing the site, however the site is
subject to regional flooding from Cooroora Creek. The proposed new buildings
associated with the development will be raised above the 100 year flood level and
located on stumps so as not to impede flood flows. A flood search will be
completed, prior to building approval to set the minimum floor heights of the
buildings.
The proposed development layout is provided in Figure 2.
