Offset Staking – Screen Two
The second Offset Staking screen is used to define the cross section of
the road that you want to offset stake.
1/2 Road Width : is the L eft and R ight width of
the road, respectively, from the centerline to the
edge of payment. (See diagram below.)
X-Slope (%) : is the L eft and R ight slope of the
road, respectively, from the centerline to the edge
of payment.
Note: A negative slope will result in water
running from the centerline toward the edge of
payment.
;

: when the above checkbox is
checked, this button allows you to select the shape of the curb, ditch,
or slope beyond the edge of pavement so cut / fill information can be
computed on this surface if a random offset is specified. The selected
shape is displayed by an icon next to the button, as well as with a
bold line in the road’s cross-sectional profile at the bottom of the
screen.
Note: The selected Shape is irrelevant if a random offset is not
specified since the nodes are always in the same place for each shape
that uses the same
Height and Offset values.
Height : is the height of the curb, ditch, or slope in feet or meters. A
positive value is considered a curb and a negative value a ditch.
Offset From Edge of Road : is the distance that the curb or ditch
extends from the edge of pavement.
