                                                                                  SDA-1116-034770

Item     Information requested
               per cent of the main channel width or that they comply with the self-assessable
               code.
             - confirm that the culvert crossing and associated erosion protection are installed
               at no steeper gradient than the waterway bed gradient
             - provide detailed designs showing that there are no drops in elevation at the
               joins of the culvert invert, apron and scour protection, and how this will be
               maintained for the life of the crossing
             - confirm which is applicable: The culvert will be buried a minimum of
               300millimetres to allow bed material deposit and reform the natural bed on top
               of the culvert base, or; The base of the culvert is the stream bed, or; The base
               of the culvert cell is roughened throughout the culvert floor to simulate natural
               bed conditions.
             - Please indicate if any baffles or other roughening elements are to be used

6.       PO25 All waterway barriers are designed, constructed and maintained to
         provide adequate fish passage for the site and fish passage is provided for the
         life of the barrier.

         Please detail how fish passage will be maintained with particular reference to
         expected or modelled hydraulic conditions from the downstream to the upstream limit
         of the crossing.

         Please confirm through providing plans that the culvert design will comply with the
         design provisions of the self-assessable code WWBW01- Part 3 Culvert Crossings. If
