Sediment & Erosion Control Do's and Don'ts

Do's

Erosion Control Matting Do 
Gravel road with drainage ditches and erosion control silt fences in a rural area.

Erosion Control Matting (ECM) provides erosion control and quicker establishment of vegetation. ECM is normally installed in swales, on steep slopes and on erosive soils.

Inlet Protection Do 
Left: A wooden frame around a storm drain marked "DUMP NO WASTE" in grass. Right: An orange object with black straps in a dirt field.

Inlet of catch basin protection comes in many forms. Inlet protections allows runoff water to enter the basin, while trapping sediment on the outside.

Sediment Trap Do 
A pond with labeled areas: "1 Foot Thick #57 Aggregate" and "ODOT Type D Rip Rap" near a small house.

The sediment trap provides a permanent pool of water for settling sediment during construction. The gravel/riprap sediment trap outlet is simpler to construct than the sediment basin outlet.

Silt Fence Do 
Silt fence separating disturbed soil from grass, with labels indicating undisturbed area and fence compaction.

A silt fence is designed to collect sediment from sheet flow and has a capacity to accept runoff from a prescribed area, depending on the slope. If the area is too large and/or the flow is concentrated, a sediment trap is the right choice.

Construction Entrance Do 
A construction site with gravel, a red tractor, vehicles, and trees in the background under a clear blue sky.

A stabilized construction site entrance is a point of entrance/exit to a site that's stabilized to reduce tracking mud and dirt onto public roads.

Don'ts

Erosion Control Matting Don't 
Field with erosion gullies near ECM, highlighted with text and arrow, hay bales and road nearby.

Extending the Erosion Control Matting (ECM) two to three feet above the channel side prohibits the formation of gullies along the ECM. Properly secured and stapled matting eliminates the need for straw bales.

Inlet Protection Don't 
Concrete drainage cover with an orange tarp on muddy ground.

Inlet protection not provided for the catch basin window.

Sediment Trap Don't 
A muddy, dry basin with a small puddle, sparse vegetation, and a drainage pipe protruding from the bank.

A sediment trap with no outlet (like the one shown above) will allow sediment to settle out in the inlet pipe (background), cause erosion downslope and jeopardize the integrity of the embankment when the pond overflows.

Silt Fence Don't 
Orange silt fence on a grassy slope with text explaining gully formation and inspection for effective sediment control.

A silt fence is designed to collect sediment from sheet flow and has a capacity to accept runoff from a prescribed area, depending on the slope. If the area is too large and/or the flow is concentrated, a sediment trap is the right choice.

Construction Entrance Don't 
Rural road with a curve sign, dirt on right side, grass, and surrounding trees.

A stabilized construction site entrance is a point of entrance/exit to a site that's stabilized to reduce tracking mud and dirt onto public roads.
