1 INTRODUCTION
1.1 Background
The purpose of this document is to provide the necessary background to, and the contents of a Flood
Emergency Management Plan (FEMP) for the proposed development at 135 Lake Weyba Drive with respect
to flood events generally, and in particular provides risk management measures for flood events greater than
the design flood event to be considered as part of a Joint Experts Report (JER) process.
The information in this report covers flood risk, concept emergency preparation, monitoring procedures,
responsibilities of body corporate and residents as well as flood management actions to be taken before, during
and after a flood.
1.2 Site Details and Characteristics
1.2.1 Site Overview and Details
The site is physically located at 135 Lake Weyba Drive, Noosaville in the Noosa Shire otherwise described as
Lot 1 on RP 36729. The site area is approximately 2ha and is approximately 30m from the shore of Lake
Weyba buffered by Lake Weyba Drive to the east. The location of the site and general features is presented
in Figure 1-1.
FIGURE 1-1 SITE LAYOUT AND LOCALITY (BASE MAP SOURCE – NOOSA COUNCIL)
The subject site is zoned Detached Housing and Open Space Conservation under the provisions of the Noosa
Plan, 2013. The surrounding land uses consist of residential dwellings to the north and south and National
Park is located to the west. Land uses along Lake Weyba Drive consist of dwellings on residential lots.
1.2.2 Site Topography
Topographical levels for the site as well as the general immediate areas are illustrated in Figure 1-2 and are
based on 2016 LiDAR data. Approximately half of the site from its western boundary is lower than 1mAHD.
The rest of the site and in the location of the proposed building envelopes, the existing ground level ranges
from 1.1m – 1.5m AHD.

1.2.3 Site Layout
Figure 1.3. presents the lot layout and shows the lot sizes vary from 1211m2 to 1.3ha, each with a defined
Building Envelope. Access is off Sail Street to service Lots 1 and 2, whereas Lots 3 and 4 have direct access
off Lake Weyba Drive.

FIGURE 1-3 PROPOSAL PLAN – RECONFIGURATION OF A LOT (1 INTO 4)
1.3 Flood Sources
The site is located adjacent to Lake Weyba, which is connected via a narrow channel to the lower reaches of
the larger Noosa River system as indicated in Figure 1-2. The Noosa River has a total catchment area of
approximately 1,900km2. The water levels in Lake Weyba can be influenced by:
◼ Tidal influences, including storm tide,
◼ Regional flooding in the Noosa River system, and
◼ Local rainfall in the Lake Weyba catchment
On this basis, preparation of the FEMP needs to consider the potential of flooding associated with these three
sources.
Further detail as to flood mechanisms relevant to the site is provided in Appendix A.

2 FORECASTS AND WARNINGS
2.1 Overview
Monitoring the weather forecasts and warnings will be the most important step in managing the flood risk of
the site. The Bureau of Meteorology (BoM) forecasts rainfall maps which can be used to estimate the daily
amount of rain expected to fall for the next 5 days through the Forecast Rainfall feature on their website
(http://www.bom.gov.au/jsp/watl/rainfall/pme.jsp). In addition to this, the BoM’s MetEye service can provide 3
hourly rainfall total estimates up to 24 hours in advance (http://www.bom.gov.au/australia/meteye/).
Real-time rainfall intensity data is available through the BoM weather radar service. The Gympie (Mt Kanigan)
Radar provides coverage for the Noosa River catchment, which is available on their website
(http://www.bom.gov.au/products/IDR083.loop.shtml#skip).
The BoM also provide weather warnings for severe weather events which may lead to flooding, which can be
located on their website (http://www.bom.gov.au/qld/warnings/) and are distributed and re-broadcast through
various media including radio.
2.2 Rainfall Gauges
There are also a number of rainfall and creek level gauges within the Noosa River catchment. The rain gauges
show the amount of rainfall which has fallen in the preceding 1 hour, 3 hour and 24 hour time periods, and the
creek level gauges provide real-time information on water levels within the waterways.
The location of the Rainfall gauges in relation to the site and the wider catchment is illustrated in Figure 3-1.
Due to the nature of flooding behaviour at the site, the rainfall gauges and BoM forecasts rainfall maps will
provide the most useful flood warning information for the site, particularly the Tewantin (RSL) Rainfall gauge
will provide rainfall coverage of most interest which is available on their website
(http://www.bom.gov.au/products/IDQ60801/IDQ60801.94570.shtml).

2.3 Noosa River Flood Warnings
The Bureau of Meteorology (BoM) in conjunction with Noosa Council run a flood warning system for the Noosa
River based on an automatic alert system of which the Tewantin River gauge, Boreen Point and Lake
Corooibah are locations of interest. The location of these gauges in relation to the site and the wider catchment
is illustrated in Figure 3-2. The gauge data is available via the BoM website (http://www.bom.gov.au/cgi-
bin/wrap_fwo.pl?IDQ60360.html).

The peak time in the 1%AEP Flood event on the Noosa River for the three river gauge sites is relatively similar.
For the evacuation procedures associated with this FEMP the Noosa River gauge site of specific interest is
the Tewantin Gauge, details of which can be seen in Table 3-2.

2.4 Site flood monitoring system
The site will be subject to flooding during large rainfall events for which Lake Weyba water levels rise in
response to severe downpours. There is the potential for failure (e.g. telecommunications or power failure) of
gauges. As a backup, it is proposed that flood height gauge and siren are to be installed to indicate depth to
residents of the site within the common property. This gauge will be installed to BOM specifications. This will
allow site specific flood monitoring in conjunction with reviewing the BOM weather warnings.

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.
Flood Emergency Management Plan | 27 February 2020

Page 32
The Noosa LDMP identifies the Noosa Local Group which coordinates disaster operations in the area. The
following key membership roles and responsibilities for management of evacuation operations and centre
management during activation for response and recovery are identified in the LDMP:
◼ Australian Red Cross acting as the Emergency Services Coordinator
◼ Community Support Officer as the Environmental Health Coordinator
And the following emergency support functions:
◼ Queensland Police Service coordinating the evacuation operations
◼ Department of Housing and Public Works for advice on buildings for use as evacuation centres
The Noosa Recovery Subplan is a subplan to the Noosa Local Disaster Management Plan which lists potential
evacuation centre locations.
Both documents are is available at Noosa Councils website (https://www.noosa.qld.gov.au/disaster-
management-plan).
3.4 Responsibilities
◼ The developer is to enter into a maintenance contract with a suitable contractor to maintain the Flood
Height Gauge and Siren to Bureau of Meteorology specifications. The Body Corporate Manager or
delegated nominated person will be responsible for continuing the maintenance contract for the life of the
development.
◼ The Body Corporate Manager or delegated nominated person and residents will be responsible for the
overall communication, implementation and periodic update of the Flood Emergency Management Plan:
Regular review (e.g. every two years) should be undertaken as new flood information may become
available. These reviews should be regarded as an essential part of the risk awareness-raising process.
◼ The Body Corporate Manager or delegated nominated person is to ensure that the driveways on common
property are well maintained.
◼ The Body Corporate Manager is responsible (for the life of the development) for ensuring that there is an
active procedure for notifying residents and occupiers, of the potential for a flood in accordance with the
Flood Emergency Management Plan. It is envisaged that this will most likely take the form a contract for
active monitoring through a third party provider.
◼ Residents are responsible for ensuring they have enough food, water and medical supplies to shelter in
place for a minimum of three days.
3.5 Conditions of Development
The following design features will be incorporated into the development to minimise risks from flooding:
3.5.1 Community Management Statement
To ensure the primary strategy of Shelter in Place can be employed during flood events, a Community
Management Statement associated with the maintenance of the common property for the development will
contain a provision advising owners and occupiers that the site at 135 Lake Weyba Drive is subject to flooding
and that the primary arrangement is to shelter-in-place.
The secondary strategy (or primary strategy for residents as detailed in section 3.6.2) is to Self-Evacuate via
the emergency evacuation route to Eenie Creek Road available to them in accordance with this Flood
Emergency Management Plan.
Flood Emergency Management Plan | 27 February 2020
135 Lake Weyba Drive, Noosaville Page 14

Page 33
3.5.2 Floor above Probable Maximum Flood (PMF)
To ensure the opportunity to shelter-in-place during flood events, any future dwellings on the site must be
conditioned to have a minimum habitable floor level above the height of the PMF, being 3.43mAHD.
3.5.3 Flood Height Gauge
Roadside flood height gauge boards are to be installed within the common property to indicate depth of
floodwaters to residents in metres AHD and provide.
Instructions on how to read the gauges will be provided are as follows:

3.6 Emergency Response Strategies
3.6.1 Overview
Rainfall forecasts as listed in Section 2 are available up to 5 days in advance, with increasing certainty as the
prediction timeframe becomes shorter.
Triggers for an Emergency Response may then be based on the following strategy:
◼ 5 Day forecast for upcoming severe weather event (i.e. heavy rainfall and/or storm event as predicted by
the Bureau of Meteorology or third party provider)
◼ Residents to be alert of potential upcoming flood risk
◼ Prepare to shelter in place or self-evacuate as detailed in section 3.6.2 and 3.6.3.
◼ Continue to monitor forecasts and warnings
◼ 3 Day forecast for upcoming severe weather event, potentially greater than 400mm rainfall
◼ Residents to be alert of potential upcoming flood risk and emergency response procedures. Suggest
early self-evacuation for those with specific medical attention requirements.
◼ 1 Day forecast – rainfall totals in excess of 300mm forecast for next 24 hours
◼ Commence Emergency Response Strategy
◼ Residents to shelter-in-place at floor levels at or above the PMF level; OR
◼ Residents to self-evacuate as per section 3.6.2
3.6.2 Shelter In Place
The primary emergency response strategy for the site is Shelter In Place.
◼ Once the site flood level gauge reaches a level of 1.3mAHD the siren is triggered and it is preferred that
residents shelter in place.
◼ Detailed Emergency Response Actions are provided in Appendix B.
◼ Once the site flood level gauge reaches a level of 1.5m AHD Must self-evacuate before a flood event, a
flood height siren will be triggered before the evacuation route is inundated:
◼ When the site flood height gauge reaches a level of 1.3mAHD (between a 1 in 20yr and 1in 50yr flood
event) a flood height siren will be triggered.
◼ Residents must self-evacuate property BEFORE Lake Weyba Drive is covered by flood water. If there
is water over road – cease evacuation and shelter in place.
◼ Detailed Emergency Response Actions are provided in Appendix B.

4 MANAGEMENT ACTIONS
4.1 Before a Flood Event
Trigger for Action: Always
◼ Body Corporate Manager of the Community Title Scheme to develop and maintain detailed emergency
procedures that take on board the recommendations presented in this report. The procedures will include
clear responsibilities for residents and property owners in the event of a flood
◼ Body Corporate Manager of the Community Title Scheme is to circulate FEMP to residents, owners and
tenants on an annual basis.
◼ Residents to be clearly communicated the emergency response procedures as part of this FEMP and
provided connection to the Noosa Local Group as identified in the Noosa Local Disaster Management
Plan, specifically to access the Noosa Recovery Subplan which lists potential evacuation centre locations.
◼ Residents to prepare Emergency Kit as per Appendix A
◼ The Body Corporate Manager is responsible for or delegating maintenance duties of the flood height
gauges as per the Community Title Scheme
◼ The Body Corporate Manager is responsible for ensuring residents have continued awareness of the
emergency response arrangements in accordance with this Flood Emergency Management Plan, e.g. via
an annual mailout to the street addresses for the benefit of residents.
4.2 When a Flood is Likely
Triggers for Action: 5 day rainfall forecast with daily 24hr totals likely to exceed 300mm
◼ Residents to be alert of potential upcoming flood risk, the potential that shelter in place may be required
(step 4.3) and if residents require specific medical attention requirements to self-evacuate (step 4.4) and
continue to monitor forecasts and warnings
◼ Residents to prepare to shelter-in-place above the PMF level with enough food and water for a period of
several days
◼ Residents to listen to local ABC Sunshine Coast 90.3FM Radio for fresh bulletins about flood and rainfall
warning
4.3 During a Flood – Shelter in Place
Triggers for Action: Major flooding in Noosa River at the Tewantin River Gauge (at 1.8mAHD), 24hr
daily totals of greater than 300mm recorded with more rainfall forecast,; OR a quantified level of
1.3mAHD greater at site flood height gauge
◼ When the flood siren is triggered when floodwaters reach a level on site at 1.3mAHD, residents are to
shelter-in-place on floor levels at or above the PMF level with enough food and water for a period of
several days
◼ If residents are not prepared to shelter in place or are required to self-evacuate as per section 3.6.2 go to
step 4.4 to self-evacuate BEFORE Lake Weyba Drive is covered by flood water. If there is water over road
– cease evacuation and shelter in place.
Flood Emergency Management Plan | 27 February 2020

Page 36
4.4 During a Flood – Self Evacuation
Triggers for Action: Major flooding in Noosa River at the Tewantin River Gauge (at 1.8mAHD), 24hr
daily totals of greater than 300mm recorded with more rainfall forecast, quantified level of 1.3mAHD or
greater at site flood height gauge
◼ A flood height siren will be issued to the whole site if forecasts suggest that significant flooding of the site
is possible. It will be issued whenever:
◼ The site flood height gauge reaches a level of 1.3m AHD (between the 2% and 5% AEP).
◼ Residents who consider they could not tolerate several days isolation and those with medical conditions
including Children, Elderly, infirm and people that may require medical attention during the period of
isolation must self-evacuate BEFORE Lake Weyba Drive is covered by flood water. If there is water over
road – cease evacuation and shelter in place.
Please note the Noosa Shire Council’s simulations of the 1992 historic event indicate the following times,
(following activation of the siren) are application:
• RL 1.3 to RL1.5 (nominally the point at which the road is inundated) = approximately 2 hours
• RL 1.5 to RL 1.8 (the point at which the road is no longer trafficable) = approximately 8 hours

5 CONCLUSION
Whilst the proposed reconfigured lots for the use of detached residential dwellings are likely to achieve the
minimum freeboard requirements above the flood levels, risk to vehicles and residents remain should they
attempt to traverse the flood waters.
The risks associated with flooding of the developed site can be managed through awareness and provides for
flood free access for vehicles and pedestrians up to and including the 1%AEP flood event in the Noosa River
from the developed site.
It is critical that all residents familiarise themselves with the risks associated with flooding and be made aware
of the early warning services and emergency access route along Lake Weyba Drive to Eenies Creek Road.
◼ Preference has been given in this FEMP for a Shelter In Place strategy above floor levels which are at
or above the PMF level. This is presented as the primary emergency response strategy. Floor levels above
the PMF that provide a high refuge area must be provided as condition of proposed development of
detached residential dwellings.
◼ The secondary strategy involves a Self-Evacuation of residents in response to the emergency siren via
the evacuation route along Lake Weyba Drive and Eenies Creek Road.

Flood Source
As outlined previously, the site is located on the banks of Lake Weyba which forms part of the Noosa River
catchment. The site is exposed to flooding from the Noosa River and from Storm Tide inundation. Flooding
from the Noosa River (of which Lake Weyba forms part) dominates the flood risk at the site and is addressed
specifically in this FEMP.
Flooding at the site can consist of any (or a combination) of the following mechanisms:
◼ slow moving ‘backwater’ type flooding from high storm-tide events,
◼ slow moving ‘backwater’ type flooding from Noosa River flooding,
◼ localised flooding in response to a localised rainfall event in the Lake Weyba catchment.
Figure A-1 illustrates the Noosa Council’s existing flood hazard mapping at the site and general locality based
on the Council interactive mapping. Figure A-2 shows Noosa Council’s Storm Tide inundation mapping.

Flood Levels at the Site
The flood levels likely to be reached on site are summarised in Table A-1. These have been sourced from the
Noosa Flood Study (2013) (referred to in Table A-1 as the Model) which was prepared by WMA Water,
documented in the WMA Water Report “Noosa River Flood Study Upgrade Volume 4 Design Event Modelling
Report Final” March 2017 and supplied to us by Noosa Council, except for the flood certificate level, also
supplied by the Noosa Council, which is included for comparison. The results indicate that there is a significant
difference (almost 0.7m) between the ‘current conditions’ 1% AEP flood level and the 2100 climate change
conditions 1% AEP flood level provided on the flood certificate.

Flood Depth and Hazard
The nature of the Noosa River and creek flooding on this site means that flood water velocities are close to
zero.
The low-lying areas of the site are inundated by flooding as frequent as the 39% flood which would be up to
0.23m in depth across the western portion of the site which is zoned as Open Space Conservation. The
proposed development includes building pad levels of 2.6mAHD placing it more than 0.3m above the 1%AEP
2100 Climate Change Flood Level.
The ground floor levels of any newly constructed residential dwelling would be at a minimum of 2.8mAHD (for
habitable parts of the building), at least 0.5m above the 1%AEP 2100 Climate Change Flood Level. The first
floor levels would therefore be a minimum of 4.9mAHD (assuming a minimum floor-to-ceiling height of a non-
habitable room such as a kitchen or laundry on the ground floor being 2.1m as per the Building Code of
Australia).
The analysis summarised in Table A-1 indicates that a PMF flood level is approximately 0.83m above the
building pad height, 0.63m above the minimum finished ground floor level and approximately 1.5m lower than
the minimum first floor level. The first floor therefore provides a refuge for events exceeding the 1%AEP
Climate Change Flood Level up to and including a PMF event.

Historic Flooding
The historical annual peak heights which have been recorded at the Tewantin gauge are illustrated in Figure
A-3. The records indicate that the highest flood level recorded at the Tewantin gauge to date was in 1968,
which peaked at 2.0m. Please note that based on other historic events, the within Lake Weyba will have been
lower than at the Tewantin Gauge. This event pre-dated the installation of the initial flood warning network
which occurred in 1987. The largest event which has occurred since the installation of the flood warning
network occurred in February 1992. Events post-1987 have been utilised in the calibration of Noosa Shire
Council’s regional hydrological/hydraulic model of the Noosa River system.
As discussed previously, there is no flood alert station within Lake Weyba. Therefore, the Noosa Shire
Council’s calibrated hydrological/hydraulic model has been used to represent the response of Lake Weyba to
regional flooding. Time-series water surface plots of the available alert gauge levels, water levels at the site
and modelled rainfall have been provided in Figure . This chart indicates that water levels in Lake Weyba may
peak prior to flood peaks occurring at the Tewantin Gauge. The chart also indicates that the February 1992
event was characterised with a lengthy period of relatively low intensity rainfall (~10mm/hr) in the lower
catchment, however areas of the upper catchment experienced 1 to 2 hours of high intensity (~40mm/hr)
rainfall approximately half way through the rainfall event.

Rates of Rise
To plan for an evacuation case, the 1992 Historic Flood Event was used to inform flood response procedures,
as this historic event is a significant event, and has been included as a scenario in Noosa Shire Council’s
hydrological/hydraulic model. Modelled hydrographs for the 1992 Historic Flood Event in the Noosa River are
shown in Figure A-4, with greater detail of the rising limb of the hydrograph provided in Figure A-5 Figure .
Flood levels within Lake Weyba adjacent to the site can rise by up to 120mm/hr.
The steepest rate of rise for the 1992 Historic Flood Event is from 0.5mAHD to 1.5mAHD, which is at a
consistent rate of 80mm/hr to 120mm/hr.
Flooding to approximately 0.5m AHD would start to affect the western portion of the site (which is not proposed
to be developed) within 5hrs of the Flood Event starting. The evacuation route to Eenie Creek Road overpass
will not become inundated until approximately 14hrs when water levels in Lake Weyba reach 1.5mAHD and
will become impassable after approximately 17hrs (approximately 1.7mAHD). This provides adequate time for
a reasonable evacuation response should larger flood events occur on the site.

Flood Duration
Isolation occurs when the lowest point on the evacuation route i.e. Lake Weyba Drive has floodwaters with a
depth above 0.3m (i.e. not deemed trafficable).
An extreme flood event like that seen in 1992 could leave future residents of the proposed development
isolated for approximately 10 hours and the site, except for the building pads, driveways and other built up
parts, inundated for a period of up to 31 hours (i.e. above 1.5mAHD).
Evacuation Risks
The site evacuation route has been assessed as starting at the Lake Weyba Drive access driveway, which is
located on the eastern property boundary as indicated in Figure A-6. For the purposes of evacuation planning,
evacuation via the Lake Weyba Drive access driveway or Sail St has been assessed.

FIGURE A-6 SITE EVACUATION ROUTE (WATERTECH 2018)
The evacuation route from the site via Lake Weyba Drive to Eenie Creek Road overpass generally has a
minimum elevation of approximately 1.5m AHD based on the 2016 LIDAR data.
The evacuation route is impacted by floodwaters originating from the Noosa River catchment in events greater
than the 2% AEP flood event.
Andres Gabarrin | 27 February 2020
135 Lake Weyba Drive, Noosaville

Page 47
In the 1992 Historic Flood Event, floodwaters of a maximum depth of 0.4m would have occurred on the
evacuation route assuming the lowest point is at the entrance of the site at approximately 1.5mAHD and the
maximum flood height for the was 1.9mAHD. Figure A-7 shows the evacuation route elevation to be in the
most part above 1.5mAHD. The 1%AEP flood level for site, as per Table 2-3 is approximately 1.61mAHD.
Therefore, the evacuation route is considered trafficable for events up to, including and, to a limited extent,
beyond the 1%AEP flood event.
FIGURE A-7 EVACUATION ROUTE ELEVATION PROFILE (SOURCE WATERTECH 2018)
Onsite Refuge Locations
The development application seeks a reconfiguration of a lot. No built form is proposed as part of this
application. However, as previously stated, the house pads will be constructed to a minimum level of 2.6mAHD,
with a minimum floor level of 3.4mAHD.
The minimum floor level, being above the PMF level then allows for refuge on site as a primary emergency

Andres Gabarrin | 27 February 2020
135 Lake Weyba Drive, Noosaville
47
Page 49
ACTIONS REQUIRED FOR PRIMARY STRATEGY “SHELTER IN PLACE”
Action 1:
No preparation for evacuation is required under Shelter in Place strategy
If you lose communications and/or cannot find relevant flood warning information, it is critical that you continue
to physically inspect the level of Flood Height Gauge at 135 Lake Weyba Drive.
Action 2:
You must prepare for widespread flooding that may cut local roads (not just Lake Weyba Drive) and disrupt
services.
Notify others of your decision:
Notify a reliable friend or relative of your decision to stay and how they can contact you.
Advise your Local Police Station in Noosa Heads that you are staying based on Lake Weyba Drive. Give
them details of your residential address and the number of persons staying.
Have arrangement for loss of power:
Assume that the flood event may result in loss of electric power. Your emergency kit should include a battery-
powered radio, torches, battery powered or gas lights and enough batteries or gas to last for the period of
power loss.
Gasoline generators may compensate for loss of electric power, but require knowledge and planning to operate
safely.
Never position a generator indoors or where its exhaust fumes may enter a living space. Remember that the
storage of adequate fuel supplies is an additional safety consideration and limits the duration of this alternate
source of power.
Have arrangement for communications:
Fully charge all electronic communication devices prior to power being lost. Only use devices sparingly to
conserve battery power. Have a fully charged portable charger for charging electronic communication devices
once power is lost.
Despite these precautions, electronic communication services will likely be lost when the flood event affects
areas other than your location.
Have arrangement for cooking and boiling water:
5865_R02_V06_Final_FEMP.docx
Prepare outdoor cooking appliances (e.g. bar-b-ques, charcoal grills and camp stoves). Ensure ample fuel
supplies are on hand.
Have arrangement for water supply
Ensure there is a sufficient supply of drinking water available. Allow for 2 litres per person, per day.

Page 50
ACTIONS REQUIRED FOR “SELF - EVACUATE”
Action 1:
If you choose to evacuate to a safer place, you must make a plan to ensure you:-
• Evacuate at the right time (i.e. BEFORE Lake Weyba Drive is covered by flood water to the
north of 135 Lake Weyba Drive);
• Have secured your house;
• Travel on a pre-determined evacuation route (considering many roads may be flooded); and
• Have secured alternative accommodation.
You should consider the following:
• Have you packed an evacuation kit?
• Have you packed emergency food and water supplies?
• Have you packed important documents and valuables?
• Have you turned off the power, gas and water mains to your home?
• Are your pets safe and secure?
• Have you secured and locked your home?
• Have you checked on your neighbours who may be elderly or disabled?
Action 2:
Prior to leaving your house check that you have packed emergency food and water supplies and your
evacuation kit.
Your evacuation kit should include the following items:
5865_R02_V06_Final_FEMP.docx
Action 3:
Andres Gabarrin | 27 February 2020
135 Lake Weyba Drive, Noosaville
49
Page 51
Communicate your intentions:
Prior to leaving, inform a reliable relative or friend of your intention to evacuate. Inform them when you will
leave, where you will go and how you can be contacted.
Advise your Local Police Station at Noosa Heads that you are evacuating. Give details of your residential
address and the number of persons leaving.
Action 4:
Check your property before departing:
Before leaving your property do a final check to ensure:
• Livestock or pets are secured on higher ground
• Your house is secure with all windows and doors locked
• All electrical appliances have been unplugged
• All power, gas and water mains have been turned off
• Any outdoor furniture has been moved inside
• Sheds and outbuildings are secured and locked
• Security lights and cameras have been activated
Final Evacuation Check List
Do you know where you will be evacuating to?
Do you know the preferred route for evacuation?
Is your vehicle full of fuel?
Have you packed your Evacuation Kit?
Have you turned off the power, gas and water mains to your home?
Are your pets safe and secure?
Have you secured and locked your home?
Have you packed emergency food & water supplies?
Have you checked on neighbours who may be elderly or disabled?
Once you complete this checklist, commence your evacuation.

For Self-Evacuation to be safe, ensure that you evacuate your property BEFORE Lake Weyba Drive is
covered by flood water.
Do not attempt to use Lake Weyba Drive when water is over the road. “If flooded, forget it”.
