Appendix D- Stormwater Management Plan · MCU23/0078

7. SUMMARY

    This Engineering Report has demonstrated that the proposed development located at 28 Eenie Creek Road, Noosaville
    QLD 4566, can be developed in accordance with Engineering Best Management Practice, Noosa Shire Council guidelines,
    QUDM 2017 and the State Planning Policy 2017. The following points summarise the findings and recommendations:


        −   The proposed development site has no flood levels or flags for building or development purposes and is
            expected to be at low risk of flooding;

        −   New stormwater connections are proposed from the development site to the existing stormwater piped network
            located along the private access roadway and the adjoining environmental zone and natural drainage channel;

        −   Minor storm events will be collected by internal stormwater infrastructure within the development sites and
            surface car parking areas. This infrastructure will convey flow towards the surrounding stormwater infrastructure
            within the surrounding private access roadways, to ultimately discharge into Eenie Creek to the south;

        −   Major storm events will be conveyed via overland flow onto the surrounding private access roadways or
            adjoining environmental zone and natural drainage channel;

        −   Stormwater detention is proposed as there will be an increase to the impervious area across all three sites as a
            result of the proposed development, which will take the form of below-ground detention tanks;

        −   In accordance with the State Planning Policy and the Noosa Shire Council Planning Scheme, stormwater quality
            treatment measures are proposed as the site area is over 2,500m 2, and quality treatment devices will be located
            within the below-ground detention tank systems; and

        −   The three sub-catchments across the development site remain unchanged due to the proposed development.
