           RE:    Operational Works application – Category 2 Levee Banks for Flood Mitigation at Daintree Estate,
           Tewantin; STAGE 2 Works (Retaining Wall)

           Please see attached an Operational Works application for works associated with flood mitigation at Daintree
           Estate, Tewantin, as follows:

                      Stage 2 works for Category 2 levee bank (CH0 to CH485, CH600-753) with works occurring in Lot 959
                       NPW1140, Lot 959 NPW1141, and Leafhaven Drive road reserve. Stage 2 works will occur on the
                       southern and western boundaries of the estate and involve diversion levee walls (besser block) to divert
                       flows around the estate and into the tributary of Wooroi Creek. Some works encroach into the adjacent
                       Tewantin National Park.

           These Stage 2 measures are part of the floodplain management measures to protect properties within the
           Daintree Estate from flood events. Other measures proposed to protect these properties include:
                Closing off some existing culverts to divert flows around the estate. These works are within Lot 993
                    SP110896 – drainage reserve within the estate.

           The flood mitigation works are currently being assessed by the Department of Environment and Heritage
           Protection - Queensland National Parks and Wildlife Service, under an Application for an interest in a protected
           area (Section 34 of the Nature Conservation Act 1992).

           For Stage 2 Operational Works – Category 2 levee banks, the following documents are attached:

                 1.    IDAS Form 1
                 2.    IDAS Form 20
                 3.    Engineering Plans 1415-01, to 40 inclusive.
                 4.    Flora and Fauna Assessment Report
                 5.    Environmental Management Plan

           This Stage 2 levee bank (constructing a retaining wall from CH0 to CH485, CH600-753) is determined to be
           Category 2 as there is zero population affected by the off-property impacts. There are no buildings subject to
           increased flood levels and/or velocities as a result of the proposed works.

           The Operational Works fee's has been calculated as follows:

                       Base Fee                                                      $ 834.00
                       Works relating to Category 2 levee banks                      $ 1,575.00
                       TOTAL                                                         $ 2,409.00

           Council’s Project Manager for these works.
