concentrated flow.

STREAM DIVERSION CHANNEL

DIVERSION

Improving, constructing or stabilizing an open ~ channel, existing stream, or ditch.
A crushed stone pad located at the construction site exit to provide a place for removing mud from tires thereby protecting public streets.
[lABOJ
A trove/way constructed as part of a construction plan including access roads, subdivision roads, parking areas and other on-site vehicle transportation routes.
A temporary channel constructed to convey flow around a construction site while a permanent structure is being constructed.
An earth channel or dike located above, below, or across a slope to divert runoff. This may be a temporary or permanent structure.

TEMPORARY DOWNDRA/N STRUCTURE

GRADE STABILIZATION
STRUCTURE
LEVEL SPREADER

A flexible conduit of heavy-duty fabric or other material designed to safely conduct surface runoff down a slope. This is temporary and inexpensive.
A paved chute, pipe, sectional conduit or similar material designed to safely conduct surface runoff down a slope.

t!J

A temporary stone barrier constructed at storm drain inlets and pond outlets.

ff
~y

Rock filter baskets which are hand-placed into position forming soil stabilizing structures.
Permanent structures installed to protect channels or waterways where otherwise the slope would be sufficient for the running water to form gullies.

(uaa)

A structure to convert concentrated flow of water into less erosive sheet flow. This should be constructed only on undisturbed soils.

f

A permanent or temporary stone filter dam installed across small streams or drainageways.

A wall installed to stabilize cut and fill slopes where maximum permissible slopes are not obtainable. Each situation will require special design.
(uaa)
A device or structure placed in front of a permanent stormwater detention pond outlet structure to serve as a temporary sediment filter.
(uaa)
A barrier to prevent sediment from leaving the construction site. It may be sandbags, boles of straw or hay, brush, logs and poles, gravel, or a silt fence.
{NDICAlE T'tl'E)
An impounding area created by excavating around a storm drain drop inlet. The excavated area will be filled and stabilized on completion of construction activities. A basin created by excavation or a dam across a waterway. The surface water runoff is temporarily stored allowing the bulk of the sediment to drop out.
A small temporary pond that drains a disturbed area so that sediment can settle out. The principle feature distinguishing a temporary sediment trap from a temporary sediment basin is the lack of a pipe or riser.
A buoyant device that releases/drains water from the surface of sediment ponds, traps, or basins at a controlled rate of flow.
(uaa)
A linear control device constructed as a diversion perpendicular to the direction of the runoff to enhance dissipation and infiltration of runoff, while creating multiple sedimentation chambers with the employment of intermediate dikes.

A temporary bridge or culvert-type structure protecting a stream or watercourse from damage
by crossing construction equipment.

A paved or short section of riprap channel at the outlet of a storm drain system preventing erosion from the concentrated runoff.

A rough soil surface with horizontal depressions on a contour or slopes left in a roughened condition after grading.

A floating or staked barrier installed within the water (it may also be referred to as a floating boom, silt barrier, or silt curtain).

To protect desirable trees from injury during construction activity.

Paved or vegetative water outlets for diversions, terraces, berms, dikes or similar structures.
