Stormwater Management Plan -OPW (A) · OPW25/0042

1.0   INTRODUCTION

This report is lodged in support of an Operational Works (OpW) application to Noosa Council on
behalf of Calile Malouf Investments seeking to develop a luxury hotel at Lots 10 and 11 SP195871,
Serenity Close, Noosa Heads.

This Revision C represents refinement of previous versions lodged and addresses conditions 46,
47 and 48 of Council’s Decision Notice-Other Change 132008.176.05 dated 17th October 2024

The proposed development follows seven stages of residential unit buildings developed by Cape
Bouvard over the greater Settlers Cove site with Alta Projects’ Engineers having completed
stormwater design, inspection and certification for all previous stages.

Design solutions presented in this report are consistent with those previously adopted with
minor refinements borne of experience.



2.0   EXISTING CONDITIONS

The subject site is currently undeveloped and supports vegetation subject to assessment and
recommendations by the Ecological Consultant.

The site falls at moderate grades away from Serenity Close towards an existing concrete
pedestrian path with informal natural wetlands areas of Noosa Inlet to the south.

The entire site consists of loose to dense, poorly graded dune sand and as such contains no
defined overland drainage paths since rainwater infiltrates directly through the permeable
surface, although a number of gentle natural gullies and swales are present over the site
particularly toward the southern boundary.

Stormwater and sewer lines within Easements R, S and F roughly bisect the site adjacent the
existing boundary between lots 10 and 11.

In order to make way for the proposed building footprint, the existing sewer and stormwater
infrastructure will need to be relocated through the site.

Previous reports proposed relocation of the sewer to Serenity Close but technical and budgetary
challenges now sees the sewer relocation proposed alongside stormwater pipework through the
site.

Lots 10 and 11 are proposed to be amalgamated as part of the development.
