NOTES,
1. Cross sections were developed from available topographic map data and have not
been physically surveyed.
2. All fill slopes are to be constructed at 1.5 horizontal to 1.0 vertical. Fill
slopes are to he benched into native soils with a bench of not Less than 10' in
width, Successive benches will be located not more than 10' apart in vertical
height, All fill must he compacted to a minimum of 90% of ASTM D -698.
3. When possible, cut slopes shall be at 1.5 horizontal to 1.0 vertical. Generally
between Sta. 4+00 and 8+00,due to severe topographic conditions, it will nor be
possible to "daylight" 1.5:1. slopes. In this section, 1.0 horizontal to 1.0 verti-
cal slopes are recommended to minimize impact on existing stability conditions.
It must be recognized that in'areas containing 1:1 slopes. more frequent ravelling
and minor sloughing will occur in cut slopes necessitating frequent ditch
maintenance.
4. In the section from Sta. 4 +40 to 5 +00, due to very severe topographic constraints,
it is not felt to be possible to maintain a 20 -foot wide template using a 1:1
out slope. In this area, a 15 -foot wide template is recommended. lfolt'ls de-
sired to maintain a 20 -foot wide template along the full length of the access
road, this may he accomplished by utilizing a gravity retaining wall system.

5. Surfacing requirements and drainage design are beyond the scope of this design.
It is assumed that a culvert will be required in the vicinity of Sta. 7 +50 to
transfer storm drainage to the cut side of the access read. tt is our under-
standing that this structure will be sized by others.
