Embankment:
Locate sediment trap as near the sediment source as topography allows,
Divert runoff from all undisturbed areas away from sediment trap.
Clear, grub, and strip all vegetation and root mat from area of embankment
Use stable mineral soil free of roots, rocks, debris, and other objectionable material.
Place fill in 9 inch lifts, maximum. Machine compact each lift. Construct
side slopes 2:1 or flatter (3: 1 recommended for backslope to improve
stability of stone Spillway) -
Overfill embankment to 6 inches above design elevation to allow for settlernent.
Outlet Section:
Excavate trapezoidal stone outlet section from compacted embankment.
Allow for thickness of stone side slopes (21" Minimum).
Install filter fabric under riprop. Extend fabric up the slope to top of embankment.
Place specified stone to lines and grades shown on plans, working small stones
into the voids to achieve a dense mass. Spillway crest must be level with
minimum inside dimension specified in pion, Measure Spillway depth from
the highest stones in the spillway to the design elevation of dam. Minimum
depth of 1.5 feet.
Keep sides of the stone outlet section at least 21 inches thick through the
level section and the downsfrecim face of dam -
