                      (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 70°
                      to the centre-line of the
                      boat ramp or slipway;
                      (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 slipway for which a winch
                      is not used to hoist or haul
                      vessels onto the boat ramp or
                      slipway is at a gradient of not
                      steeper than—
                      (i) if the surface is treated
                      by using a method
                      mentioned in paragraph
                      (b)(i) or (ii)—1:7; or
                      (ii) otherwise—1:10;
                      (d) if a relevant planning scheme
                      standard is more stringent
