Workers on Tuesday began building a berm in the Oso mudslide debris field. The temporary wall of rock and dirt, which will be approximately 2,000 feet long, will drain the water from the area around C-Post Road and Highway 530, allowing search and rescue teams to access previously flooded areas.

A truck dumps rock at the end of the berm on Wednesday morning. The berm will allow rescuers to pump flood waters out of the search area.

Flood waters cover the path of C-Post Road during construction of the berm. A team of contractors is working with eight members of the Army Corps of Engineers.

Snohomish County Public Works Director Owen Carter talks about the construction of the berm. Dogs had been leading searchers to the area, but floodwater made it inaccessible, prompting the construction of the berm.
