D. Impact Justification and Mitigation
1 Avoidance and Minimization
1a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
Launch location is outside of river's active channel and will not disturb the riverbed No structures will protrude into flowing water
lb Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
Construction equipment will operate outside of flowing water and no excavation of the riverbed will occur Construction materials will be staged
outside of riparian buffer Construction requires use of a mini- excavator and extensive handwork, no heavy machinery

EARTHWORK SPECIFICATIONS
FOUNDATION PREPARATION PLACEMENT MOISTURE CONTENT & COMPACTION
Foundations for earthfill shall be stripped to remove vegetation and other Earthfill shall not be placed until the required excavation and foundation preparation have been completed and During placement and compaction of earthfill and earth backfill, the
unsuitable material or shall be excavated as specified. the foundation has been inspected and approved by the engineer. Earthfill shall not be placed upon a frozen moisture content of the material being placed shall be maintained within
surface nor shall snow, ice, or frozen material be incorporated in the earthfill matrix. the specified range.
Except as otherwise specified, earth foundation surfaces shall be graded to
remove surface irregularities and shall be scarified parallel to the axis of
the fill or otherwise acceptably scored and loosened to a minimum depth
of 2 inches. The moisture content of the loosened material shall be
controlled as specified for the earthfill, and the surface material of the
foundation shall be compacted and bonded with the first layer of earthfill
as specified for subsequent layers of earthfill.
VEGETATION SPECIFICATIONS
ALL SLOPES GREATER THAN 21 SHALL BE SEEDED WITH HYDROSEEDING EQUIPMENT. STEEP
SLOPES SHALL HAVE SCARIFIED SURFACES WITH TRENCHES 1 -2 INCHES DEEP AND 6 -12 INCHES
APART ACROSS THE SLOPE IN WHICH THE SEED CAN L -ODGE AND GERMINATE.
PLANTING MIXTURE
Tall Fescue: 40 -60 pounds / acre
Annual Rye: 25 -30 pounds I acre
TIME AND FERTILIZER"
Lime. 2.000 pounds ' acre of finely ground dolomitic limestone
Fertilizer: 400 pounds, acre of 10 -10 -10 or equivalent
—These rates also apply when hydroseeding
MULCHING
All slopes steeper than 3.1 ANDiOR Susceptible to erosion from runoff shall be mulched with an erosion control
blanket (North American Green SC 150B or equivalent) Blankets shall be anchored in accordance with
manufacturer's specifications.
Earthfill shall be placed in approximately horizontal layers. The thickness of each layer before compaction shall
not exceed the maximum thickness 9— inches. Materials placed by dumping in piles or windrows shall be spread
uniformly to not more than the specified thickness before being compacted.
Hand compacted earth backfill shall be placed in layers whose thickness before compaction does not exceed the
maximum thickness specified for layers of earth backfill compacted by manually directed power tampers.
Earth backfill shall be placed in a manner that prevents damage to the structures and allows the structures to
assume the loads from the earth backfill gradually and uniformly. The height of the earth backfill adjacent to a
structure shall be increased at approximately the same rate on all sides of the structure.
All other areas may be mulched with dry. unchopped. unweathered small grain straw or hay free of seeds
of competing plants. Spread at the rate of 1 2 tons per acre depending upon the season. Evenly spread mulch over
the area by hand or mechanical equipment. Apply mulch uniformly so that 25% of the ground surface is visible.

The application of water to the earthfill material shall be accomplished at
the borrow areas insofar as practicable.
Water may be applied by sprinkling the material after placement on the
earthfill, if necessary. Uniform moisture distribution shall be obtained by
disking.
Material that is too wet when deposited on the earthfill shall either be
removed or be dried to the specified moisture content prior to compaction.
If the top surface of the preceding layer of compacted earthfill or a
foundation or abutment surface in the zone of contact with the earthfill
becomes too dry to permit suitable bond, it shall either be removed or
scarified and moistened by sprinkling to an acceptable moisture content
before placement of the next layer of earthfill.
Earthfill — Earthfill shall be compacted according to the following
requirements for the class of compaction specified:
Class A compaction —Each layer of earthfill shall be compacted as
necessary to provide the density of the earthfill matrix not less than the
minimum density specified in Section 10 or identified on the drawings. The
earthfill matrix is defined as the portion of the earthfill material finer than
the maximum particle size allowed in the reference compaction test
method specified (ASTM D698 or ASTM D1557).
Class B compaction —Each layer of earthfill shall be compacted to a mass
density not less than the minimum density specified.
