SR 530 Landslide - Roadway Clearing

Project Summary

Following the catastrophic Oso, WA landslide that covered a mile of the roadway in Northwest Washington, IMCO crews worked around the clock to complete this contract for WSDOT in under a month. The scope included: the very careful removal of debris, erosion and water pollution control, and slope stabilization off State Route 530.

The project was completed a week ahead of the very tight scheduling requirments, and IMCO saved WSDOT 47% of the original contract value.
