Structure is located within a natural
ravine. Unless the structure were designed to bridge
the ravine or built over a culvert system, so as to allow
surface water to flow beneath, a considerable amount
of earth would need to be moved to divert surface
water and not cause flooding into the structure.
Figure 3.17-B
Locating the structure at B would
allow surface water to flow away from the structure by
means of contour grading, without the costly bridge or
culvert structure that would be needed in area A

Figure 3.17-C
Locations A and B are similar. However,
the natural topography of A would tend to divert
surface water to either side of the structure, while the
topography of site B would tend to concentrate water
toward the center of the structure location. More
grading would be required to accommodate a struc-
ture at site B in order to divert surface water from the
structure.
Figure 3.17-d
The two site C locations would require
less earthwork modification to accommodate a pro-
posed structure than sites A, B, and C, and they are less
steep than the two B sites
