CONSTRUCTION SPECIFICATIONS:
1. Clear, grub, and strip the area under the embankment of all vegetation and root mat. Remove all
surface soil containingamounts of
high g organic matter, and stockpile or dispose of it properly. Haul all
objectionable material to the designated disposal area.
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. Overfill
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.
• 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
• 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. Discharge inlet water into the basin in a manner to prevent erosion. Use temporary slope drains or
diversions with outlet protection to divert sediment -laden water to the upper end of the pool area to
improve basin trap efficiency (References: Runoff Control Measures and Outlet Protection).
10. Ensure that the stone spillway outlet section extends downstream 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).
11. Direct emergency bypass to natural, stable areas. Locate bypass outlets so that flow will not damage
the embankment.
12. Stabilize the embankment and all disturbed areas above the sediment pool and downstream from the
trap immediately after construction (References: Surface Stabilization).
13. 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.
14. Install porous baffles as specified in Practice 6.65, Porous Baffles.
Maintenance:
Inspect temporary traps at least weekly and after each significant (1 1/2 inch or greater) rainfall
event and repair immediately. Remove sediment, and restore the trap to its original dimensions
when the sediment has accumulated to one-half the design depth of the trap. Place the
sediment that is removed in the designated disposal area, and replace the part of the gravel facing
that is impaired by sediment.
Check the structure for damage from erosion or piping. Periodically check the depth of the spillway
to ensure it is a minimum of 1.5 feet below the low point of the embankment. Immediately fill any
settlement of the embankment to slightly above design grade. Any riprap displaced from the
spillway must be replaced immediately.
After all sediment -producing areas have been permanently stabilized, remove the structure and all
unstable sediment. Smooth the area to blend with the adjoining areas, and stabilize properly
(References: Surface Stabilization).

CONSTRUCTION SPECIFICATIONS.
1. CONSTRUCT THE SEDIMENT BARRIER OF STANDARD OR EXTRA STRENGTH
SYNTHETIC FILTER FABRICS.
2. ENSURE THAT THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 24
INCHES ABOVE GROUND SURFACE. (HIGHER FENCES MAY IMPOUND VOLUMES OF
WATER SUFFICIENT TO CAUSE FAILURE OF THE STRUCTURE).
J. 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 4 FEET
MINIMUM OVERLAP TO THE NEXT POST.
4. SUPPORT STANDARD FILTER FABRIC BY WIRE MESH FASTENED SECURELY TO
THE UPSLOPE SIDE OF THE POSTS. EXTEND THE WIRE MESH SUPPORT TO THE
BOTTOM OF THE TRENCH. FASTEN THE WIRE REINFORCEMENT, THEN FABRIC ON
THE UPSLOPE SIDE OF THE FENCE POST. WIRE OR PLASTIC ZIP TIES SHOULD
HAVE MINIMUM 50 POUND TENSILE STRENGTH.
5. WHEN A WIRE MESH SUPPORT FENCE IS USED, SPACE POSTS A MAXIMUM OF
8 FEET APART. SUPPORT POSTS SHOULD BE DRIVEN SECURELY INTO THE
GROUND A MINIMUM OF 24 INCHES.
6. EXTRA STRENGTH FILTER FABRIC WITH 6 FEET POST SPACING DOES NOT
REQUIRE WIRE MESH SUPPORT FENCE. SECURELY FASTEN THE FILTER FABRIC
DIRECTLY TO POSTS. WIRE OR PLASTIC ZIP TIES SHOULD HAVE MINIMUM 50
POUND TENSILE STRENGTH.
7. EXCA VA TE A TRENCH APPROXIMA TEL Y 4 INCHES WIDE AND 8 INCHES DEEP
ALONG THE PROPOSED LINE OF POSTS AND UPSLOPE FROM THE BARRIER.
8. PLACE 12 INCHES OF THE FABRIC ALONG THE BOTTOM AND SIDE OF THE
TRENCH.
9. BACKFILL THE TRENCH WITH SOIL PLACED OVER THE FILTER FABRIC AND
COMPACT. THOROUGH COMPACTION OF THE BACKFILL IS CRITICAL TO SILT FENCE
PERFORMANCE.
10. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.
MAINTENANCE. -
INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL.
MAKE ANY REQUIRED REPAIRS IMMEDIA TEL Y. SHOULD THE FABRIC OF A
SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE,
REPLACE IT PROMPTLY. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE
ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE
ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING
CLEANOUT. REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS
AND BRING THE AREA TO GRADE AND STABILIZE IT AFTER THE CONTRIBUTING
DRAINAGE AREA HAS BEEN PROPERLY STABILIZED.
CONS TRUC TION SPECS:
9. CLEAR & GRUB THE AREA AROUND THE SILT FENCE
OUTLET AND PROPERLY DISPOSE OF DEBRIS.
2. PLACE GRAVEL TO THE SPECIFIC GRADE AS SHOWN
PER THE DETAIL.
J. PROPERLY OVERLAP STONE BEYOND EDGES OF SILT
