' Dimensions shown are minimum.
Construction 1. Clear. grub, and strip the area under the embankment of all vegetation and
Specifications root mat. Remove all surface soil containing high amounts of 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 tree 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 soil.
• Place the filter fabric between the riprap and the soil. Extend the fabric
across the spillway foundation and sides to the top of the dam; or
• Excavate a keyway trench along the center line of the spillway foundation
extending up the sides to the height of the dam. The trench should be at
least 3 feet deep and 2 feet 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 feet 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 over filled
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 ofstone
with a dso size of 9 inches (class B erosion control stone is recommended) and
a maximurn 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).

1. ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED
FOR STABILITY AND OPERATION FOLLOWING EVERY RUNOFF -PRODUCING
RAINFALL, BUT IN NO CASE, LESS THAN ONCE EVERY WEEK AND WITHIN
24 HOURS OF EVERY HALF -INCH RAINFALL.
2. ALL POINTS OF EGRESS WILL HAVE CONSTRUCTION ENTRANCES THAT
WILL BE PERIODICALLY TOP -DRESSED WITH AN ADDITIONAL 2 INCHES OF
#4 STONE: TO MAINTAIN PROPER DEPTH. THEY WILL BE MAINTAINED IN A
CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING THE SITE.
IMMEDIATELY REMOVE OBJECTIONABLE MATERIAL SPILLED WASHED OR
TRACKED ONTO THE CONSTRUCTION ENTRANCE OR ROADWAYS.
3. SEDIMENT WILL BE REMOVED FROM HARDWARE CLOTH AND GRAVEL
INLET PRO':-ECTION, BLOCK AND GRAVEL INLET PROTECTION, ROCK
DOUGHNUT INLET PROTECTION AND ROCK PIPE INLET PROTECTION WHEN
THE DESI-,^�NED STORAGE CAPACITY HAS BEEN HALF FILLED WITH
SEDIMENT. ROCK WILL BE CLEANED OR REPLACED WHEN THE SEDIMENT
POOL NO LONGER DRAINS AS DESIGNED. DEBRIS WILL BE REMOVED
FROM THE ROCK AND HARDWARE CLOTH TO ALLOW PROPER DRAINAGE.
SILT SACKS WILL BE EMPTIED ONCE A WEEK AND AFTER EVERY RAIN
EVENT SEDIMENT WILL BE REMOVED FROM AROUND BEAVER DAMS,
DANDY SACKS AND SOCKS ONCE A WEEK AND AFTER EVERY RAIN EVENT.
4. DIVERSION DITCHES WILL BE CLEANED OUT IMMEDIATELY TO REMOVE
SEDIMENT OR OBSTRUCTIONS FROM THE FLOW AREA. THE DIVERSION
RIDGES WILL ALSO BE REPAIRED. SWALES MUST BE TEMPORARILY
STABILIZED WITHIN 21 CALENDAR DAYS OF CEASE OF ANY PHASE OF
ACTIVITY ASSOCIATED WITH A SWALE.
5, SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE
WHEN IT BECOMES HALF FILLED. THE SEDIMENT FENCE WILL BE
REPAIRED AS NECESSARY TO MAINTAIN A BARRIER. STAKES MUST BE
STEEL. `:"TAKE SPACING WILL BE 6 FEET MAX. WITH THE USE OF EXTRA
STRENGTH FABRIC, WITHOUT WIRE BACKING. STAKE SPACING WILL BE 8
FEET MAX. WHEN STANDARD STRENGTH FABRIC AND WIRE BACKING ARE
USED. ilF ROCK FILTERS ARE DESi3NED AT LOW POINTS IN THE
