                                                            EXECUTIVE SUMMARY


    Simmonds and Bristow were commissioned by the Scanlon Property Group Pty Ltd to develop
    a   Stormwater Management Plan (SWMP)and Sediment Erosion Control Plan (SECP)for the
    proposed Essence of Peregian development.

    The SECP assessed the erosion hazard and risk based                                                                  on          the soil and   topography of the
    development site.            The SECP provides information how to manage the erosion and off-site
    export of soil from the development site, and a statement of the personnel responsible for
    establishing and maintaining all erosion and sediment control measures.

    The SWMP described the management of stormwater from the developed site and         upslope
    sources  beyond the development area. The SWMP provided pre-development measurements
    of water quality and soil parameters from the proposed development area, and computer model
    outputs (MUSIC 4) that demonstrate compliance of the design stormwater quality with required
    guideline standards. These standards were agreed at the Joint Experts Conference, and are
    consistent with loads reductions required by the Queensland Water Quality Guidelines (DERM
    2009).

    Plans that describe the stormwater treatment train (Appendix A) and outputs from computer
    modelling used to support the stormwater design (Appendix B) are appended. These plans
    show the proposed site layout, the location of bioretention trenches, building areas, plumbing
    layout, and the structure of bioretention trenches within the development area.

    Procedures for maintaining stormwater treatment units                                                          (Appendix D) and implementing the
    Sediment And Erosion Control Plan  (Appenaix C; Appendix E) are enclosed with this plan.
    These procedures describe how to control erosion, and miqjmise off-site exports of sediment
    and     nutrients from the            proposed development                                  area,                during            the construction         and   post-
    construction phases. A plan for monitoring water quality to demonstrate compliance with water
                                                                                                                                        .
