Erosion & Sediment Control

What This Service Involves

Disturbed soil on public projects must be controlled to prevent sediment from reaching the storm system, as required by Ecology's construction stormwater rules. Our crews install and maintain silt fence, wattles, inlet protection, check dams, and stabilized entrances. We monitor and repair these best management practices through the wet season and after storm events, keeping the site inspection-ready. Documentation supports the stormwater pollution prevention plan and any Construction Stormwater General Permit obligations.

Benefits

Best management practices installed to Ecology construction stormwater standards; ongoing maintenance that keeps controls functioning; storm-event monitoring and rapid repair; sediment kept out of drains and receiving waters; documentation supporting pollution prevention plan compliance

Our Process

1) Review the site and pollution prevention plan to plan required practices; 2) Install silt fence, inlet protection, and other controls; 3) Inspect and repair controls after storms and on schedule; 4) Document conditions to support permit compliance

What Affects the Cost

Site size and extent of soil disturbance; types and quantity of controls required; inspection and maintenance frequency; repair and replacement after storm events; stabilization materials for exposed soils

Best Time of Year

Controls are critical throughout Western Washington's October-to-April wet season, when the construction permit imposes tighter requirements.
