       Figure 2 - Elevation Profile through site (based on 1m LIDAR data). ‘A’ marks site access from Upper
       Pinbarren Road; ‘B’ marks proposed lodge; Star marks bridge over creek; Circle marks level crossing.

There are two creek crossings on the site, the primary crossing located at the site entrance is via a bridge and a
second level crossing north of the caretakers house where a spillway overtops from the pond.

(It should be noted that both bridge and level crossing works are proposed to improve the flood resilience and
better notify site users of the risks at these locations.)

SITE FLOOD RISK
The primary source of flood risk to the site and in particular site users relates to flash flooding within the site
and wider catchment from heavy rainfall events. Specifically, there are number of ponds on the site which pick
up runoff from rainfall within the site and overflow down the site and into the main creek that forms the south
western border of the site. Although these ponds and other features are significantly lower than any of the
existing or proposed buildings on the site and would not pose direct risk to those buildings, access routes to and
from the site could be subject to inundation and flooding in more severe events. The purpose of this Flood
Management Plan presented in Appendix 1 is to provide a quick reference guide for the site owners and users
of the site in an emergency situation.

We trust this information is satisfactory for your current needs. Should you have any questions, please feel free
to contact the undersigned

FLOOD MANAGEMENT PLAN
The following should be provided to all site managers. Site managers should be appropriately trained and made
clearly aware of the flood risks pertaining to the site, safe areas of evacuation and preventative measures. Some
general measures are included below (this is not an exhaustive list but provides a number of key items that
should be implemented and followed by guests and staff).

It should be noted that the site is not within a specified Flood Alert/Warning Area, however it is advised that the
site users sign up to the Noosa Flood Alert System which would give the closest approximate of flood risk to the
site.


DEFINITIONS:
Flood Alert – These are provided through local media and Bureau of Meteorology. The site manager shall review
these sources daily to monitor predicted weather patterns and where necessary advise guests that heavy rainfall
is expected.
Flood Warning – These are official alerts to warn against the real risk of flooding and immediate action should
occur to manage risks to people and property.


KEY INFORMATION SOURCES:
Below are key information sources. These should be made available to all site managers and guests and
reviewed daily by site managers.


Internet/World Wide Web
Flood Warnings, River Height Bulletins and other weather related data is available on the Bureau's Web page
at http://www.bom.gov.au . The Queensland Flood Warning Centre website
is http://www.bom.gov.au/qld/flood .


Telephone Weather
Flood Warnings are available through a recorded voice retrieval system, along with a wide range of other
weather related and climate information.

Main Directory                             Phone     1900 955 360
Flood Warnings                             Phone     1300 659 219


EVACUATION AREAS
It is considered that the existing buildings on site area suitable as places of safe refuge, as these are elevated
well above existing water features and water courses and are not deemed to be at immediate risk of inundation.
Should evacuation from any building be required, a risk assessment of the conditions should be undertaken,
namely an assessment of the evacuation route. Evacuation should only occur if flood depths are less than 25cm
(or as advised by emergency services).

FLOOD EMERGENCY PROCEDURE
        On receipt of a FLOOD ALERT, the individual property owners and occupiers should:

            Monitor the situation via local media;
            Make themselves aware of forecast local weather conditions;
            Alert both current visitors, and those scheduled to arrive, of the situation;
            Prepare to evacuate if necessary.

        On receipt of a FLOOD WARNING, the individual property owners and occupiers should:

            Follow advice to “go in, stay in, and tune in”;
            Move all vehicles to an area outside of the potential flood extent, if safe to do so;
            Alert scheduled visitors that they should seek alternative accommodation;
            Be prepared to follow instruction from the Emergency Services.

        On receipt of a SEVERE FLOOD WARNING, the individual property owners and occupiers should:

          Follow advice to “go in, stay in, and tune in”;
          Remain attentive to local media forecasts and news bulletins;
          Do not evacuate unless instructed to do so by the Emergency Services;

1.1     Upon receipt of a Flood Warning, site users are advised to remain on site in a designated place of safe
        refuge. Evacuation from the site should only be undertaken if flood levels to the site access bridge are
        below the bridge deck, and spillway levels are less than 250mm deep; or as directed by emergency services.

1.2     If evacuation from site is required or advised, it is suggested to utilise the alternative site access through
        the neighbour’s property.
