Flood Impact Assessment – 305 Lake McDonald Drive Cooroy


1.              INTRODUCTION
1.1             Background
Water Technology Pty Ltd (WT) has been commissioned by Como Glasshouse P/L on behalf of Martoo
Consulting Pty Ltd (Martoo) to undertake a flood impact assessment and flood management plan for
an existing Greenhouse structure located at the D’VineRipe Tomato Farm, 305 Lake McDonald Drive
Cooroy.
A development application under Council file reference MCU14/0039 for a Material Change in Use
application has been previously submitted to Noosa Council in 2014. We understand that this
application was made following Council’s determination that the since constructed greenhouse at the
site was deemed to be an intensification of use and accordingly required development approval.
Council has since issued an Information Request (IR) for the application dated 25 June 2014 under
Council reference 01569. This IR requested further information against a number of items and in the
context of flooding included a flood impact assessment as well as a flood management plan under
Items 1 and 2.

1.2             Purpose and Intent
This report has been prepared to specifically address Items 1 and 2 of Council’s IR dated 25 June 2015.
Accordingly, this report has been prepared in 2 distinct chapters as follows: ‐
Chapter 2 – Flood impact assessment, which includes the following: ‐
           Background information;
           Site description;
           Summary of hydraulic modelling methodology;
           Overview of modelling results (existing and post‐developed); and
           Discussion of impacts.
Chapter 3 – Flood Management Plan, which includes the following: ‐
           Available flood warning at the site;
           Rate of rise of flooding;
           Evacuation routes and egress;
           Measures to protect the existing infrastructure during flood events; and
           Appropriate strategy and site specific measures to minimise flood risks at the site and
            potential contamination from hazardous material stored at the site.


Further details relating to the methodology and findings for the assessments are discussed separately
in the chapters of this report which follow.
