        1.      INTRODUCTION


                This report, the Stormwater Management Plan, details the proposed stormwater
                management strategies for the proposed Unit development.


                The stormwater Strategy is designed in accordance with the Noosa Council’s Stormwater
                Planning Policy as well as the State Planning Policy.




        2.      SITE DESCRIPTION AND PROPOSED USE


                The site is currently a vacant block of land of 594m2 . It is proposed (see Appendix A for
                design drawings) that three units be constructed on site. When combined with paved
                areas there is an approximate 455m2 of impermeable surface


                The site is to be used for private residences to Appendix A for drawings detailing the
                proposed location of Units.



        3.      PAVEMENT RUNOFF TREATMENT AND INFILTRATION


                The runoff from all pavement areas shall be directed through a system of stormwater pits
                and pipework to the LPOD identified as the Noosa Council Stormwater System, via the
                Kerb and Channel in Willam Street.




        4.      STORMWATER QUANTITY


                The rainfall data has been calculated as per QDUM and shows a non-worsening volume
                of 6m3 of stormwater. Therefore, the stormwater design includes a 2000l detention tank
                in each unit.


                The minimum detention volume per unit shall be 2000L. Larger tanks may be used for
                water harvesting and re-use, however, 2000L shall be made available for detention
                volume in each tank.
