Debris from a landslide this morning in Maple Valley completely blocked a stretch of the Cedar River near Southeast 214th Street and Highway 169. No injuries were reported and no one was evacuated.
The clogged river caused flooding to seven properties in the area, causing some water damage to six houses, according to the Kent Fire Department, but the river has since resumed flowing. The slide occurred about 10:30 a.m.
“Fortunately this is a rural area and there are very few homes for how many acres were affected,” fire department Captain Kyle Ohashi said.
The King County Sheriffs Office has ordered an emergency closure of the Cedar River – from Highway 169 to the Maxwell Road at Maple Valley Highway – for all activities, including fishing, boating, floating and swimming.
The landslide – a triangle shape on the side of the hill – is roughly 300 feet across at the base and 300 feet at its peak. Because large fir trees are along the edge of the face, some hanging precariously, Ohashi said the site will need to be monitored closely.
“The large 100-foot fir trees, they are actually hanging down the hillside right now,” he said. ” The first heavy wind or rain that we get, they could come down.”
Small segments of the area are still sliding and the King County Sheriff’s office will continue monitoring the area.
