1. INTRODUCTION
Engeny Australia Pty Ltd (Engeny) have been engaged by Calile Malouf Investments Pty Ltd to prepare a Local Overland Flow Assessment for
a proposed Operational Works (OPW) development for application resort complex and shop at 3 & 7 Serenity Close Noosa Heads QLD 4567
(the Site). The Site is located within the Noosa Shire Council (NSC or Council) Local Government Authority (LGA). Detailed overland flow
modelling has been completed at a level of detail appropriate for Operational Works approval to confirm Alta Project’s proposed realigned
drainage and overland flow design through the site is appropriate in achieving the design requirements for the project (refer Section 1.4). A
Material Change of Use (MCU approval was granted over the site on 24 October 2024 (Application ref: 132008.176.05).


1.1        Site Characteristics
The Site has an approximate area of 2.4 ha and is located within the Tourist Accommodation zone, with part of the site also zoned as
Environmental Management and Conservation (Constrained Land). The existing lot is occupied by two dwelling houses at the eastern and
western side of the Site, with some light vegetation cover. And existing stormwater drainage easement and stormwater line traverses the
middle of the site and discharges to the existing NSC reserve to the south (noting the overland flow path does not follow the stormwater
network). The Site is sloping from the front of the Site (northeast) to the rear (southwest), with surface elevations ranging from RL 22 m AHD
to RL 8 m. The drainage path flows from northeast to southwest and drains into to Noosa River.

The proposed Site layout and preliminary engineering plans are provided in Appendix A and B of this report and the location of the Site is
shown in Figure 1.1 below.
