        2.1.3 Existing Land Use

                 The development site presented in Figure 2.1 is identified as Lot 102 on SP241371.
                 The site is currently vacant. The site is bound by Gateway Drive on the east and
                 west. The eastern Gateway Drive joins the Eumundi-Noosa Rd/Rene St roundabout.
                 The western leg of Gateway Drive joins the eastern leg of Gateway Drive and
                 Eumundi-Noosa Rd. A vacant land parcel shares the southern boundary of the site. A
                 faction impervious of 50% has been assumed for the site and catchment contributing
                 to the underground drainage system in Gateway Drive.


       2.2       Developed Conditions


        2.2.1 Description of Proposed Development

                 The proposed development will consist of a tyre retailer (578.9m2) and provide 15 car
                 parks. The site will have a 95% fraction impervious area.


        2.2.2 Proposed Stormwater Drainage Infrastructure

                 The proposed stormwater drainage concept consists of the following:
                      An internal stormwater drainage network for the proposed development site
                       designed to convey 10 year ARI flows;
                      Flows associated with 10 year ARI rain events will be directed to the existing
                       drainage infrastructure on Gateway Drive;
                      Provision for 100 year ARI flows to be conveyed to Gateway Drive.
