Lot 30 on SP170751                                                         Conceptual Stormwater Management Plan
115 Eumundi Noosa Road, Noosaville                                                               Project No: K4277

         Maintenance is primarily concerned with:
              Maintenance of flow to and across the permeable pavement;
              Preventing undesired overgrowth vegetation;
              Removal of accumulated sediments; and
              Litter and debris removal.

         Maintenance will include:
              Pressure washing permeable pavers every 12 months.



7.0 CONCLUSIONS
         Odyssey Consulting Group has been commissioned by Good Shepherd Lutheran College to prepare a
         Conceptual Stormwater Management Plan (CSWMP) for the Proposed Carpark at 115 Eumundi Noosa
         Road, Noosaville.

         This CSWMP details the conceptual planning, layout and design of the stormwater management
         infrastructure for both the construction and operational phases of this development.

         Hydraulic analysis demonstrated that the development will result in an increase in peak runoff as
                                                                                             3
         compared with the pre development scenario. An open-air detention basin with 126 m of volume is
         proposed to mitigate the increase in flows from the development.

         A combination of two bio retention basins, 20 m and 4m respectively and 219m of permeable
         pavement is proposed for the operational phase of the development to treat stormwater runoff. A
         sediment and erosion control plan is provided for the construction phase of the development and
         shall be implemented by the contractor and developer.
