Prelim. Grading PlanNotes:
1. Contractor must insure that no slopes exceed 4-:1
2. Contractor must insure that all areas will be graded to drain.
5. Contractor must field verify all existing utilities prior to construction.
4-. Contractor must notify engineer of any discrepancies.

EARTHWORK NOTES
1. Site Preparation
All trees, stumps, brush, abandoned structures, roots, vegetation, rubbish and
any other undesirable matter should be properly removed end disposed of.
2. Compacting Area to be Riled
All areas to be filled should be disced or bladed until uniform and free from large
clods, brought to a moisture content between opt[mum and five (5) percentage
points above the optimum moisture vo.lue for claye~ soils and between optimum
to +3 percentage points fo.r si,lty cloy soils and soil containing limestone
fragments and compacted to between 95 and 100 percent of optimum density in
accordance with ASTU D 698.
3. Fill Materials
Off-site materials to used for fill should be approved by the Soils Engineer.
There should be no roots, yes.et, orion or any other undesirable matter in the soil,
end no rocks larger than six (6) inches i,n diameter.
4. Depth of Mixing of Fill Layers
The fill material should be placed in level, uniform layers, which, when
compacted, should hove a moisture content end density conforming to the
stipulations coiled for herein. Each layer should be thoroughly mixed during the
spreading to insure the uniformity of the layer. The fill thmkness should not
exceed lO-inch loose lifts.
5. Rock
There should be no Fock incorpoFoted within the ~11 which exceeds six (6) inches`
in its greatest dimension, and no large rocks wild be permitted within twelve (12)
inches of the finished subgrade.
6. Moisture Content
Prior to and in conjunct;on with the compacting operation, each layer should be
brought to the proper moisture content as determi,ned by ASllvl D 698, within
plus or minus three (3) percentage points of optimum for fill containing limestone
rock pieces and between optimum and five percentage points above the optimum
for clayey soils.
Amount of compaction
After each layer has been properly placed, mixed and spread, it should be
thoroughly compacted to between 95 and 100 percent of Standard Proctor
Density os determined by ASTM D 698.
Compaction of Fill Layers
Compaction equipment should be of such design that it will be one to compact
the fill to the specified density. Compaction of each layer shall be continuous
over its entire oreo.
10.
Density Tests
Field Density tests should be made by the Soils Engineer or his representative.
Density tests should be taken in the compacted material below the disturbed
surface. After each layer of fill, compaction tests, as necessary, should be made
by the Soils Engineer, If the moterio,ls foil to meet the density specified, the
course should be reworked as necessary to obtain the specified compaction.
Supervision
Supervision by the Soils Engineer should be of such continuity during the grading
operation that he con certify that oli cut and filled areas were graded in
accordance with the accepted specifications.

Slope Control
Embankment slopes should not be steeper than a ratio of three (5) horizontal to
one (1) vertical for .el.thor fill or cut slopes. Any slope, existing or proposed,
steeper than three (3) feet in height should incorporate stabilization methods to
include erosion control, embankment stabilization and other slope control
measures as required by the slope control specialist.
