Emergency Erosion Control

What This Service Involves

Exposed or failing slopes can erode rapidly during Western Washington's heavy rains, threatening roads, culverts, and adjacent waterways. Our crews deploy silt fence, wattles, matting, and check dams to stabilize soil and control runoff before further damage occurs. Measures are installed to meet your NPDES permit and Ecology stormwater requirements, keeping sediment out of protected waters. Installations are inspected and maintained through the storm event until permanent stabilization can be scheduled.

Benefits

Stabilizes failing slopes before erosion damages infrastructure; Keeps sediment out of streams and protected waterways; Meets NPDES and Ecology stormwater compliance requirements; Provides ongoing inspection through the active storm period

Our Process

1) Assess the erosion threat and identify runoff pathways; 2) Install silt fence, wattles, matting, and check dams as needed; 3) Verify measures meet permit and stormwater standards; 4) Inspect and maintain controls through the storm event

What Affects the Cost

Length and steepness of slope requiring stabilization; Type and quantity of erosion control materials needed; Proximity to sensitive waters and permit conditions; Site access for crews and materials; Emergency deployment timing during active weather

Best Time of Year

Emergency erosion work concentrates from October through April when sustained rainfall drives the highest runoff and slope-failure risk.
