Att: Patrick Murphy – Coordinator Planning
Re: Development application for a Material Change of Use (34 x Multiple Dwellings), over land at 101-105 Eumundi Noosa
Road Noosaville, and legally described as Lot 1 on RP 849431 & Lot 1 RP230931

Dear Patrick,

We refer to Council’s Information Request, dated 12 January 2021 , regarding the abovementioned application. In
accordance with s13.2 of the Development Assessment Rules, we hereby provide all of the information requested as
follows:

Council Issue 1 – Stormwater
It is noted that the proposal includes a proprietary device to treat the stormwater. This is contrary to Performance
Outcomes O7 and O9 of the Water Quality and Drainage Code of the Noosa Plan 2020

The use of the proprietary underground stormwater treatment device in this instance is not supported as it has not been
shown that use of a vegetated treatment system is not possible at this site and performance of the proposed system has
not been verified through an independent national testing protocol (SQIDEP)

Information Required
Provide a revised stormwater treatment system and management plan which incorporates use of vegetated treatment
systems as required by Specific Outcome O7 of the Water Sensitive Design Code.

Response
The use of an underground proprietary stormwater treatment device is no longer proposed. Accordingly, a revised Site
Based Stormwater Management Plan has been prepared by Morgan Consulting Engineers (refer to Attachment A). This
revised stormwater strategy incorporates the use of a vegetated treatment system, as outlined in the Water Sensitive
Design code.

Council Issue 2 – Stormwater Quality
Provide a revised stormwater management plan incorporating a stormwater detention system which addresses the
following issues:
       i.    Demonstrate that stormwater discharges onto neighbouring land will not be concentrated for all events up to
             the 1%AEP event. Consideration should be made to adapting the detention basin design such that there is no
             spillway discharge for the 1%AEP event
