                                                                                              23616DA


133. Tabulated hydrologic and hydraulic calculations that demonstrate the adequacy or otherwise of
     the existing site stormwater drainage system shall be submitted in conjunction with a
     Development Permit for Operational Works. Such calculations shall include any remedial
     measures necessary to rectify defects in the existing system. Where proposed site drainage is
     to be connected to the existing system, the calculations shall clearly demonstrate the adequacy
     of the existing drainage network to accept the additional stormwater flows.
134. Stormwater drainage shall include measures to protect proposed allotments from run-off from or
     to surrounding land. The design shall also address controls for gross pollutants, nutrient runoff,
     oil and grease, and silt and sediment (in accordance with the approved Environmental
     Management Plan).
135. Underground stormwater systems shall be designed in accordance with Noosa Council’s
     Engineering Design Standards, and shall be connected, where possible to Council's existing
     drainage systems.
136. An easement of minimum width 4.0 metres shall be granted in favour of Council over any
     stormwater pipes that traverse private property.
137. The design plans detailing surface levels, which shall be controlled across the site of the
     development to create a major storm event overland flow path system to cater for the 1:100
     year design storm, shall be submitted in conjunction with a Development Permit for Operational
     Works. Any overland flow from external catchments shall be accepted and incorporated in the
     major event surface flow drainage system through the site. Overland flows shall be discharged
     in a safe manner and the product of velocity time depth shall not exceed 0.4 m²/sec.
138. The design plans are to show how stormwater runoff within and from the site is to be controlled
     both during construction and permanently. The plans are to indicate measures to be taken to
     prevent erosion and the export of sediment from the site in accordance with the approved
     Environmental Management Plan.
139. An easement for drainage in favour of Council shall be created over the full length and width of
     major storm event surface flow paths within the site at no cost to Council.
140. A minimum floor level freeboard of 0.5m shall be provided for habitable and storage areas
     above the top water level of the stormwater overland flows.
141. Details of any proposed estate entrance signage shall be submitted in conjunction with an
     application for a Development Permit for Operational Works for either roadworks or
     landscaping. A $1500 fee shall accompany the application.
      The design shall conform to Council's "Signage Policy - Development Estate Entrance".
142. The proposed names of new roads (public and private) and parks shall be lodged with the
     application for a Development Permit for Operational Works.
      Names are to be selected from any of the following categories:-
      142.1.Easily pronounced words of Murri languages.
      142.2.Names or words of local significance or historical interest.
      142.3.Flora, fauna, industry, topographical, geological and similar features and terms relative to
            the district.
      142.4.Surnames of persons of merit or historical significance.       (Personal names should be
            avoided.)
      Approval will not be given to a name that is the same or similar to the name of another road in
      the Shire, or of a road in close proximity in a neighbouring Shire. Names that are not easily
      pronounced, or may cause confusion to emergency services are to be avoided.
143. All street signs on new roads (public and private) and parks shall be erected prior to works
     being accepted on maintenance.
