3             FLOOD EMERGENCY RESPONSE
3.1           General
The general flood risks identified at the site and include:
◼     The risk to people’s safety;
◼     The risk of damage to property;

In the event of wide-scale flooding of the Noosa River Catchment, these risks manifest via:
◼     Inundation of the premises – resulting in risk to people, property and the environment; and
◼     Inundation of the road network and site egress – again, resulting in risk to people and property.

There are also ancillary risks to people, property, environment and operations that can occur coincident with
flooding, including:
◼     Storm damage of the premises and property. These can result in torn roofs, shattered windows, damage
      from fallen trees, lost or destroyed caravans etc.
◼     Loss of power.
◼     Contaminated water supplies or sewage surcharge.
◼     Constrained access/egress through intense rainfall, winds, fallen trees, debris, fallen powerlines, etc.

The items above may or may not occur coincident with flooding and can occur to any property regardless of
whether they are located within a floodplain. However, the FEMP does also give due consideration to these
items which are risks that can hinder the proper execution of the FEMP.

3.2           Risk Management Philosophy for the Site
The overall approach to managing flood risk for the site is proposed as follows:

      1. Provide flood risk management for events up to the design (1% AEP) event by appropriate design
         including elevated fill platforms for residential buildings, and further elevated ground floor levels for
         residences, and

      2. Provide flood risk management for events larger than the design (1% AEP) event by:

              a. Shelter in place on floor levels which is at or above the Probable Maximum Flood (PMF) level.

              b. Residences with specific medical attention requirements must self-evacuate in advance of
                 flooding over Lake Weyba Drive.

      3. Ensure an awareness of flood risk (from minor through to major and extreme floods) for residents
         through the specification and ongoing maintenance via body corporate arrangements of a Flood
         Emergency Management Plan (FEMP).

      4. Ensure ongoing operation of the installed Flood Height Gauge and siren via body corporate
         arrangements.

3.3           Local Disaster Management Plan
The Noosa Local Disaster Management Plan 2018 (LDMP) in compliance with the Queensland Disaster
Management Act 2003, considers a wide range of potential disaster events including flood events and details
specific strategies to prevent, prepare for, respond to and recover from disasters.
