1tf2li• .
8. EARTH WORK BALANCE
A. The Contractor shall confirm all earthwork quantities
prior to start of construction. If an excess or
shortage of earth is encountered, the Contractor
shall confirm with the Owner and Engineer the
requirements for stockpiling, removal or importing
of earth.
B. Minor adjustments to the grades may be required
to eorthwork balances when minor excess material
or shortages are encountered. It is recognized
by the parties hereto that the calculations of the
the Engineer in determining earthwork quantities
shall be accomplished in accordance with the
American Socleiy of Civil Engineers Standards for
such calculations. Further, that these calculations
are subject to the interpretations of soil borings
as the physical limits of the various soil types,
the allowable variation in finish grade and compaction
permitted the contractor, and that all of these
parameters may cause either on excess or shortage
of actual earthwork materials to complete the project.
If such an actual minor excess or shortage of
materials occurs, the contractor shall contact the
Engineer to determine if ad' stment con be made
to correct the imbalance of earth.
9. TESTING
A. Contractor shall hire at Contractors expence an independent
soil testing service to assure soil compaction with scope
of testing to be appproved by Engineer. Copies of test results
shall be submitted to the Engineer.

Seedbed Preparation
Apply lime to roise the pH to the level needed for species being
seeded. Apply 23 pounds of 12 -12 -12 analysis fertilizer (or equivalent) per
1000 sq. ft. (approximately 1000 pounds per acre) or fertilize according to
test. Application of 150 tbs. of ammonium nitrate on areas low in organic
rnatter and fertility will greatly enhance vegetative growth.
Work the fertilizer and lime into the soil to a depth of 2 -3 inches
with a horrow, disk or roke operated across the slope as much as possible.
Seeding
Select o seed mixture based on protected use of the area (Figure 5 -2),

Mulch is to be applied at 2,000 to 3,000 pounds per acre in areas not
covered by erosion control blanketing. Mulch must be anchored using a mulch
