Standard Cross-Sections.
It is a small amount of precipitation or rainfall only that the road builder here must take care of. Very wisely the last legislature passed a law establishing standard cross-sections for the roads in this state. Figures [1], [2], [3], [4], [5] and [6] show in a clearer way what these cross-sections are, than these can be shown in the law by the use of words only.
The elevation of the crown of the road above the fence line varies from four inches to eighteen inches, the amount depending on the width of the street, and the depth of the drain ditches on the sides of the roadway is as shown some two feet below the grade of the fence line.
The roadways and sidewalks as the figures giving the cross-sections show, all have such slopes, that water falling upon these surfaces will flow quickly into the drain ditches.
