I modified your code to fix a few of the problems it had, and made the
dimensions a bit easier to work with.  I hope you'll find that it looks
nicer (I'm not talking about the indentation, but the clarity).

You have some fine textures, here.  Keep it up!

#include "colors.inc"
#include "woods.inc"

#declare Wall_Texture = texture{
    pigment{ color White-(White-Khaki)*0.495 }
    normal{ wrinkles 0.2 }
}

#declare light_wood= pigment {P_WoodGrain7A  color_map {M_Wood7A} }
#declare  dark_wood= pigment {P_WoodGrain14A color_map {M_Wood14A} }

#declare board_length= 1.5;
#declare board_width= 0.25;

#declare Floor_Texture = texture{
    pigment{
        gradient y triangle_wave
        pigment_map {
            [ 0.0 light_wood ]
            [ 1.0 dark_wood ]
        }
        warp{ repeat board_length*z offset 0.37*y }
        warp{ repeat board_width*x offset board_length*5/2*z }
    }
    normal {
        boxed
        slope_map {
            [ 0.5 < 1, 0 > ]
            [ 1.0 < 0, 0 > ]
        }
        bump_size 0.1
        scale < board_width, 1, board_length >
        warp{ repeat board_length*z }
        warp{ repeat board_width*x offset board_length/2*z }
    }
}
