PART 3 - EXECUTION
3.1 SUBMITTALS: APPROVAL OR REJECTION
6 A. Items within Transmittals will be reviewed for overall design intent and will receive one of the
7 following Actions:
8 A - FURNISH AS SUBMITTED
9 B - FURNISH AS NOTED (BY ENGINEER)
10 C - REVISE AND RESUBMIT
11 D - REJECTED
12 B. Transmittals returned with approval "A" or "B" are considered ready for fabrication and
13 installation. If for any reason a transmittal that has an "A" or "B" approval is resubmitted, it must
14 be accompanied by a letter defining the changes that have been made and the reason for the
15 resubmittal. The Contractor shall assure that previously approved documents are destroyed when
16 they are superseded by a resubmittal as such.
17 C. Transmittals with Approval "A" or "B" combined with Action "C" (Revise and Resubmit) or "D"
18 (Rejected) will be individually analyzed giving consideration as follows:
19 1. The portion of the transmittal given "C" or "D" will not be distributed (unless previously
20 agreed to otherwise at the Preconstruction Conference). The "C" or "D" drawings will be
21 marked up and returned to the Contractor. It shall be the Contractor's responsibility to
22 ensure that these items are corrected and resubmitted.
23 2. Items marked "A" or "B" will be fully distributed.
24 3. If a portion of the items or system proposed are acceptable, however, the major part of the
25 individual drawings or documents are incomplete or require revision, the entire submittal
26 may be given "C" or "D" action. This is at the sole discretion of the Architect/Engineer. In
27 this case, some drawings may contain relatively few or no comments or the statement,
28 "Resubmit to maintain a complete package." Distribution to the Owner and field will not be
29 made (unless previously agreed to otherwise).
30 D. Failure to include any specific information specified under the submittal paragraphs of the
31 specifications shall result in the transmittal being returned to the Contractor unapproved.
32 E. All costs, associated with the review of any shop drawing resubmitted more than once shall be
33 borne by the Contractor with said costs being deducted from the lump sum amount shown in the
34 Contractor's proposal.
35 F. In addition to calculations stamped and returned "E. Engineer's Review Not Required," other
36 transmittals such as submittals which the Engineer considers as "Not Required," submittal
37 information which is supplemental to but not essential to prior submitted information, or items
38 of information in a transmittal which have been reviewed and approved in a prior transmittal,
39 will be returned with action "E. Engineer's Review Not Required."

28 3.2 INSTALLATION
29
A. Temporary Diversions:
30
1.
Remove and dispose of vegetation or other objectionable material.
31
2.
Excavate parabolic, trapezoidal, or V-shaped channel with a side slope of 2:1 or flatter, 3:1
32
where vehicles cross.
33
3.
A permanent vegetative cover is required for diversion channels with grades between 0.2
34
and 3%.
35
4.
Ensure that the minimum cross-section meets all design requirements and that the top of the
36
dike is not lower at any point than the design elevation plus the specified settlement.
37
5.
Provide sufficient room around diversions to permit regrading and clean-out.
38
6.
Vegetate the ridge immediately after construction, unless it will remain in place less than 30
39
working days.
40
B. Excavated Drop Inlet Protection (Temporary):
41
1.

6. Protect weep holes by gravel.
7. When the contributing drainage area has been permanently stabilized, seal weep holes, fill
the basin with stable soil to final grading elevations, compact it properly, and stabilize.
C. Fabric Drop Inlet Protection (Temporary):
1. Space stakes evenly around the perimeter of the inlet a maximum of 3 feet apart, and
securely drive them into the ground, approximately 18 inches deep. They should be driven
close to the drop inlet so that overflow will fall directly into the structure.
2. To provide stability, frame with 2 x 4 inch wood strips around the crest of the overflow area
at a maximum of 1.5 feet above the drop inlet crest.
3. Fasten fabric securely to the stakes and frames. Joints must be overlapped to the next stake.
The bottom 12 inches of the fabric should be entrenched with at least 4 inches of crushed
stone or 12 inches of compacted soil as backfill.
4. Ensure that both fabric and supporting stakes are sufficiently strong to hold a 1.5 ft. head of
water without failures.
5. The top of the frames and fabric must be well below the ground elevation downslopes from
the drop inlet to keep runoff from bypassing the inlet.
6. It may be necessary to build a temporary site on the down slope side of the structures to
prevent bypass flow. Improved performance and sediment storage volume can be obtained
by excavating the area.
D. Temporary Sediment Trap:
1. Clean, grub, and strip the area under the embankment of all vegetation and root mat before
construction begins. Remove all surface soil containing high amounts of organic matter.
2. Ensure that fill material for the embankment is free of roots, woody vegetation, organic
matter, and other objectionable material. Place the fill in lifts not to exceed 9 inches and
machine compact it. Over fill the embankment 6 inches to allow for settlement.
3. Construct the outlet section in the embankment. Protect the connection between the riprap
and the soil from piping by using filter fabric or a keyway cutoff trench between the riprap
structure and the soil.
a. Place the filter fabric between the riprap and soil. Extend the fabric across the spillway
foundation and sides to the top of the dam; or
b. Excavate a keyway trench along the centerline of the spillway foundation extending up
the sides to the height of the dam. The trench should be at least 2 ft. deep and 2 ft. wide
with 1:1 side slopes.
4. Clear the pond area below the elevation of the crest of the spillway to facilitate sediment
cleanout.
5. All cut and fill slopes should be 2:1 or flatter.
6. Ensure that the stone (drainage) section of the embankment has a minimum bottom width of
3 ft. and maximum side slopes of 1:1 that extend to the bottom of the spillway section.
7. Construct the minimum finished stone spillway bottom width, as shown on the plans, with
2:1 side slopes extending to the top of the overfilled embankment. Keep the thickness of the
sides of the spillway outlet structure at a minimum of 21 inches. The weir must be level and
constructed to grade to assure design capacity.
8. Material used in the stone section should be a well -graded mixture of stone with a d50 size
of 9 inches (class B erosion control stone is recommended) and a maximum stone size of 14
inches. The stone may be machine placed and the smaller stones worked into the voids of
the larger stones. The stone should be hard, angular, and highly weather -resistant.
9. Ensure that the stone spillway outlet section extends down- stream past the toe of the
embankment until stable conditions are reached and outlet velocity is acceptable for the
receiving stream. Keep the edges of the stone outlet section flush with the surrounding
ground and shape the center to confine the outflow stream (References: Outlet Protection).
10. Direct emergency bypass to natural, stable areas. Locate bypass outlets so that flow will not
damage the embankment.
11. Stabilize the embankment and all disturbed areas above the sediment pool and downstream
from the trap immediately after construction (References: Surface Stabilization).

12. Show the distance from the top of the spillway to the sediment cleanout level (one-half the
design depth) on the plans and mark it in the field.
13. Ensure that the spillway crest is level and 1.5 feet below the top of the dam at all points.
14. Remove sediment and restore capacity to original trap dimensions when sediment has
accumulated to 1/2 design depth.
E. Sediment Fence (Silt Fence):
1. Construct the sediment barrier of the specified synthetic filter fabrics.
2. Ensure that the height of the sediment fence does not exceed 18 inches above the ground
surface. (Higher fences may impound volumes of water sufficient to cause failure of the
structure.)
3. Construct the filter fabric from a continuous roll cut to the length of the barrier to avoid
joints. When joints are necessary, securely fasten the filter cloth only at a support post with
overlap to the next post.
4. Support standard strength filter fabric by wire mesh fastened securely to the upslope side of
the posts using heavy duty wire staples at least 1 inch long, or the wires. Extend the wire
mesh support to the bottom of the trench.
5. When a wire mesh support fence is used, space posts a maximum of 8 ft. apart. Support
posts should be driven securely into the ground to a minimum of 18 inches.
6. Extra strength filter fabric with 6 -foot post spacing does not require wire mesh support
fence. Staple or wire the filter fabric directly to posts.
7. Excavate a trench approximately 4 inches wide and 8 inches deep along the proposed line of
posts and upslope from the barrier (Figure 6.62a).
8. Backfill the trench with compacted soil or gravel placed over the filter fabric.
9. Do not attach filter fabric to existing trees.
F. Rock Dam:
1. Clear the areas under the embankment and strip it of its roots and other objectionable
material. Clear the reservoir area to facilitate sediment removal.
2. Excavate a cutoff trench a minimum of 2 feet deep and 2 feet wide with 1:1 side slopes
under the total length of the dam at its centerline. Line the trench with extra -strength filter
fabric before backfilling with rock. Apply filter fabric under the rock fill embankment, from
the upstream edge of the keyway to the downstream edge of the apron. Overlap the material
a minimum of 1 foot at all joints, with the upstream strip laid over the downstream strip.
3. Construct the embankment with well -graded rock and gravel to the size and dimensions
shown on the drawings. It is important that rock abutments be at least 2 foot higher than the
spillway crest and at least 1 foot higher than the downstream face of the dam, all the way to
the toe, to prevent scour and erosion at the abutments.
4. Sediment -laden water from the construction site should be diverted into the basin reservoir
at the furthest area from the dam.
5. Construct the rock dam before the basin area is cleared to minimize sediment yield from
construction of the basin. Stabilize immediately all areas disturbed during the construction
of the dam except the sediment pool (References: Surface Stabilization).
6. Safety. Sediment basins should be considered dangerous because they attract children. Steep
side slopes should be avoided. Fences with warning signs may be needed if the trespassing
is likely. All state and local requirements must be followed.
G. Check Dams:
1. Place stone to the lines and dimensions shown in the plan on a filter fabric foundation.
2. Keep the center stone section at least 9 inches below natural ground level where the dam
abuts the channel banks.
3. Extend stone at least 1.5 feet beyond the ditch banks to keep overflow water from
undercutting the dam as it re-enters the channel.
4. Set spacing between dams to assure that the elevation at the top of the lower dam is the
same as the toe elevation of the upper dam.
5. Protect the channel downstream from the lowest check dam, considering that water will
flow over and around the dam.
02272-5

1 6. Make sure that the channel reach above the most upstream dam is stable.
2 7. Ensure that channel appurtenances, such as culvert entrances below check dams, are not
3 subject to damage or blockage from displaced stones.
4 H. Seeding: See section 02930.
5 I. Temporary Gravel Construction Entrance/Exit:
6 1. Clear the entrance and exit area of all vegetation, roots, and other objectionable material and
7 properly grade it.
8 2. Place the gravel to the specific grade and dimensions shown on the plans, and smooth it.
9 3. Provide drainage to carry water to a sediment trap or other suitable outlet.
10 4. Use geotextile fabrics because they improve stability of the foundation in locations subject
11 to seepage or high water table.
12 J. Rock Pipe Inlet Protection:
13 1. Clear the pipe inlet area of all vegetation, roots, and other objectionable material.
14 2. Place stone to the lines and dimensions shown on the plan.
15 3.3 MAINTENANCE
16 A. Temporary Diversions:
17 1. Inspect weekly and, after every rainfall, remove sediment from the flow area and repair the
18 diversion ridges. Also check and maintain outlets.
19 2. When the protected area is permanently stabilized, remove the ridges and the channel to
20 blend with the natural ground level and appropriately stabilize it.
21 B. Excavated Drop Inlet Protection (Temporary):
22 1. Inspect, clean, and properly maintain the excavated basin after every storm until the
23 contributing drainage area.
24 2. Remove sediment from the basin when the basin volume has been reduced by one-half.
25 3. Spread excavated material evenly over the surrounding land or stockpile and stabilize it
26 appropriately.
27 C. Fabric Drop Inlet Protection (Temporary):
28 1. Inspect the fabric barrier after each rain and make repairs as needed.
29 2. Remove sediment from the pool area as necessary to provide adequate storage area for the
30 next rain.
31 3. When the contributing drainage area has been adequately stabilized, remove all materials
32 and any unstable sediment and dispose of them properly. Bring the disturbed area to the
33 grades of the drop inlet and smooth and compact it. Appropriately stabilize all bare areas
34 around the inlet.
35 D. Temporary Sediment Trap:
36 1. Inspect temporary sediment traps after each period of significant rainfall. Remove sediment
37 and restore the trap to its original dimensions when the sediment has accumulated to one -
38 half the design depth of the trap. Place the sediment that is removed in the designated
39 disposal area and replace the contaminated part of the gravel facing.
40 2. Check the structure for damage from erosion or piping. Periodically check the depth of the
41 spillway to ensure it is a minimum of 1.5 feet below the low point of the embankment.
42 Immediately fill any settlement of the embankment to slightly above design grade. Any
43 riprap displaced from the spillway must be replaced immediately.
44 3. After all sediment -producing areas have been permanently stabilized, remove the structure
45 and all unstable sediment. Smooth the area to blend with the adjoining areas and stabilize
46 properly.
47 E. Sediment Fence (Silt Fence):
48 1. Inspect sediment fences at least once a week and after each rainfall. Make any required
49 repairs immediately.
50 2. Should the fabric of a sediment fence collapse, tear, decompose, or become ineffective,
51 replace it promptly. Replace burlap every 60 days.
02272-6

3.
Remove sediment deposits as necessary to provide adequate storage volume for the next
2
rain and to reduce pressure on the fence. Take care to avoid undermining the fence during
3
cleanout.
4
4.
Remove all fencing materials and unstable sediment deposits and bring the area to grade.
5
Stabilize it after the contributing drainage area has been properly stabilized.
6
F. Rock Dam:
7
1.
Check sediment basins after each rainfall. Remove sediment and restore original volume
8
when sediment accumulates to about one-half the design volume.
9
2.
Check the structure for erosion, piping, and rock displacement after each significant
10
rainstorm and repair immediately.
11
3.
Remove the structure any any unstable sediment immediately after the construction site has
12
been permanently stabilized. All water and sediment should be removed from the basin
13
prior to dam removal. Sediment should be placed in designated disposal areas and not
14
allowed to flow into streams or drainageways during structure removal.
15
4.
Smooth the basin site to blend with the surrounding area and stabilize.
16 G. Check Dam:
17 1. Inspect check dams and channels for damage after each runoff event.
18 2. Anticipate submergence and deposition above the check dam and erosion from high flows
19 around the edges of the dam. Correct all damage immediately. If significant erosion occurs
20 between dams, install a protective riprap liner in that portion of the channel (Practice 6.3 1,
21 Riprap-lined and Paved Channels).
22 3. Remove sediment accumulated behind the dams as needed to prevent damage to channel
23 vegetation, allow the channel to drain through the stone check dam and prevent large flows
24 from carrying sediment over the dam. Add stones to dams as needed to maintain design
25 height and cross section.
26 H. Seeding. See Section 02930.
27 I. Temporary Gravel Construction Entrance/Exit: Maintain the gravel pad in a condition to prevent
28 mud or sediment from leaving the construction site. This may require periodic topdressing with
29 2 -inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as
30 necessary. Immediately remove all objectionable materials spilled, washed, or tracked onto
31 public roadways.
32 J. Rock Pipe Inlet Protection:
33 1. Inspect stone arrangement weekly and after every rainfall event.
34 2. Maintain specified dimensions and remove sediment buildup when the sediment level is 1/2
35 the height of the rocks.
36 3.4 NEAR COMPLETION OF CONSTRUCTION

2. During transportation, protect materials from wind and sun to prevent tops and roots from
drying out.
3. Protect tops of plants from damage. Plants with damaged tops will be rejected.
4. For purpose of inspection and planting identification, attach durable, legible labels to bundle
or container of plant material delivered at the planting site. State correct plant name and size
of each plant in weather -resistant ink on labels.
5. Do not prune trees and shrubs at nursery.
B. Planting Season:
1. Plant deciduous shade trees and shrubs any time the ground is suitable between October 15
and June 1.
2. Plant evergreen material between September 1 and June 1.
3. Plant ground covers between March 15 to June 1.
C. Planting Procedure:
1. Indicate locations of plants for approval by Engineer before excavating plant locations.
2. In event underground construction, utilities, obstructions, or rock are encountered in
excavation of plantings, secure alternate locations from Engineer. Make said changes
without additional compensation. Where tree locations fall under existing overhead wires, or
crowd existing trees, adjust locations as directed by Engineer.
3. Excavate pits and beds as necessary and in accordance with American Standard for Nursery
Stock. Loosen bottom of pits prior to planting. Excavation is unclassified, excavate all
materials without additional cost.
4. Tree and shrub pits to be circular in shape with vertical sides at least 1 FT greater in
diameter than ball diameter. Pit to be of sufficient depth to provide 6 IN of planting soil
under ball when set to natural grade.
5. Shrub and ground cover beds:
a. Plant shrubs used in mass plantings in individual holes of required size. Strip all sod
from among mass planting.
b. For ground cover beds, remove sod from within limits of bed. Add soil amendments as
specified and mix or rototill with existing topsoil to a depth of 6 IN.
6. Set plants straight or plumb, in locations when indicated and at such level that after
settlement they bear same relationship to finished grade as they did in their former setting.
Carefully tamp planting soil under and around base of balls to prevent voids. Remove
burlap, rope and wires from top of balls. Do not remove burlap from sides and bottom of
balls.
7. Backfill plants with planting soil. Tamp to 1/2 depth of pit and thoroughly water and puddle
before bringing backfill to proper grade. After planting has been completed, flood pit again
so that backfill is thoroughly saturated and settled.
8. After planting is complete, form a level saucer 3 IN high around each tree extending to limit
of plant pit for watering purposes.
9. Mulch plant pit after saucer has been shaped. Mulch to limits of pit and uniformly over
ground cover beds to a depth of 3 IN. In mass plantings of shrubs, mulch entire area
uniformly among shrubs to a depth of 3 IN. If mulching is delayed and soil has dried out,
water plants thoroughly before spreading mulch.
10. Staking: Stake trees immediately after planting as detailed on Drawings or in accordance
with Nursery Standards.
11. Wrap deciduous trees 2 IN or more in caliper by neatly overlapping wrapping material
between ground line and second branch. Place ties at top and bottom of wrapping material
and not more than 12 IN apart between top and bottom ties.
12. Remove dead or damaged branches. Thin deciduous material to about two-thirds of initial
branching. Remove only dead or damaged branches from evergreens.
13. Water plants during planting operations. Water each plant a minimum of once each week
until final acceptance. Apply sufficient water to moisten backfill about each plant so that
moisture will extend into the surrounding soil.
