 boat ramp or private slip way is designed and      The design and construction of the boat ramp or slip way is
 constructed in a way to ensure the safe            consistent with the following standards—(a) subject to paragraph
 movement of vehicles or persons over the boat      (d), the upper surface of a boat ramp or slip way has a width of
 ramp or slip                                       no less than 3.6m; (b) subject to paragraph (d), the whole
 way.                                               upper surface of a boat ramp or slip way is treated to prevent it
                                                    from becoming slippery by using any of the following methods—
                                                    (i) forming grooves over the surface, as close as possible to
                                                    40mm wide, 20mm deep and 150mm apart, and at an angle
                                                    as close as possible to 70º to the centre-line of the boat ramp or
                                                    slip way; (ii) covering the surface with a substance ordinarily
                                                    used on slippery surfaces to prevent
                                                    skidding; (iii) making, through a physical act, the surface coarse
                                                    before it sets, including, for example, by raking the surface;
                                                    (c) subject to paragraph (d), the upper surface of a boat ramp or
                                                    slip way for which a winch is not used to hoist or haul vessels

                                                    than— (i) if the surface is treated by using a method mentioned
                                                    in paragraph (b)(i) or (ii)—1:8; or (ii) otherwise—1:10;
                                                    (d) if a relevant planning scheme standard is more stringent than
                                                    the standard mentioned in paragraph (a), (b) or (c)—the relevant
                                                    planning scheme standard, to the extent it is more stringent than
                                                    the standard mentioned in paragraph (a), (b) or (c).

 14.1 Prescribed tidal work that is a bridge does   The design and construction of the bridge, including any             Not applicable
 not adversely affect existing public use of any    abutment connected with the bridge, is consistent with the
 tidal water, including, for example, use of the    following standards— (a) subject to paragraph (b), the clearance
 tidal water for canoeing, swimming or other        levels under a bridge are high enough to allow continued
 recreational activities.                           public use of any tidal water over which it is constructed;
                                                    (b) if a relevant planning scheme standard is more stringent than
