MAKEPEACE ISLAND RESORT                                                  FLOOD EMERGENCY PLAN

Makepeace Island has surface levels below the first report level of the Regional Flood Alert
System, being 1.0 AHD at Tewantin, and below the calculated 1 in 2 year river flood level event
of 1.3 m AHD.
Therefore this Flood Emergency Plan and Procedures cannot be solely dependent upon the information
provided by the Queensland Flood Warning Network.
Makepeace Island must therefore implement its own independent Alert System that can be followed
based upon nominated gauge heights at the Makepeace Island jetty.
We recommend that Makepeace Island install, maintain and monitor an on­site Alert System. The
system should consist of;
       Installation of River Height Gauge at Jetty, with markers as detailed – refer diagram below.




                                  ·   Highest Astronomical Tide (HAT)
                                  ·   Mean High wet Springs (MHWS)
                                  ·   Mean Low Wet Springs (MLWS)
       Visual identification – Automated flashing strobe linked to the jetty gauge and activated when
        the river level reaches 0.7 AHD.
       Audible identification – Automated alarm linked to the jetty gauge and activated when the river
        level reaches 0.7 AHD; and
       Automated identification of impeding flood risk – Autodialler which provides sms warnings to the
        phone numbers of the nominated responsible personnel, and activated when the river level
        reaches 0.7 AHD
       Installation of secondary redundant gauge at main buildings in the event the jetty gauge alert
        system fails.
