                 1. Introduction
                 Colliers Engineering and Design have been engaged by PSP Developments Pty Ltd to prepare a Stormwater
                 Management Plan (SMP) in support of a development application to Noosa Shire Council (NSC) over land
                 located at 33 Pavilion Street, Pomona (Lot 4 RP809059). This investigation supports the Operational Works
                 (OPW) design for 8 residential lots. The site has an existing building at Lot 1 and no works are required to
                 create lot 1.

                 The proposed outcome of this document is to identify stormwater management options that could be
                 implemented within the development in order to achieve the requirements and targets of NSC Planning
                 Scheme “Water Quality and Drainage Code” as well as the relevant provisions of State Planning Policy (SPP
                 2017). The intent of the codes associated with these documents will be achieved through the appropriate
                 integration of stormwater management options within the proposed residential land-use. The objectives of
                 this Stormwater Management Plan are to:

                           Detail the proposed stormwater quality management strategy and how the load reduction
                            objectives specified by the State Planning Policy (SPP, DSDIP 2017) and NSC Planning Scheme are
                            achieved during the operational phase of the development;

                           Consider suitable Stormwater Quality Improvement Devices (SQID’s) based on Water Sensitive
                            Urban Design (WSUD) principles;

                           Outline the maintenance requirements for the proposed stormwater quality improvement
                            devices;

                           Ensure the development achieves non-worsening of stormwater flows downstream of the site;
                            and

                           Demonstrate how the lawful point of discharge requirements for the site will be achieved.

                           Demonstrate development is located outside of Flood Hazard Overlay Mapping.

                 The proposed development layout and preliminary engineering drawings is provided in Appendix A.




                 1.1    Site Characteristics
                 The location of the proposed development site is shown in Figure 1-1, with a total land holdings area
                 covering 3.33ha. The site is consistent with a rural residential land use type with some wooded vegetation
                 cover over the site. The site is accessed by Pavilion Street to the east and Majestic Place to the south and is
                 bounded by private allotments to the north, east and south. Cooroora Creek is located in the adjacent
                 property to the west.
