Landslide Pushes Oregon’s Hwy. 101 More Than 200 Feet By Lori Tobias CEG CORRESPONDENT
More than a foot of rain in less than four days has wiped out a section of Highway 101 in Curry County, Ore., just north of the California border. The slide in the Hooskanaden Creek area has cut off the town of Brookings from large truck deliveries and has forced travelers to use a winding, narrow mountain road that is in places one lane and gravel. The slide area is historically troublesome, but this is one for the record books. “It’s the worst we’ve ever seen without exception,” said Court Boice, Curry County Commissioner. “It’s the most unstable ground. When they built this road in 1959-60, they didn’t look ahead. ODOT worked so hard on it last year. It was kind of a mild winter, but we still had erosion and movement. They’re in the tough position of continually adding pavement which adds weight. We’re just lucky there was a detour for this one.” The detour is about 25 mi. over Carpenterville Highway, the original Highway 101. The Oregon
More than a foot of rain in less than four days has wiped out a section of Highway 101 in Curry County, Ore., just north of the California border.
Department of Transportation has restricted use of the highway to trucks no longer than 40 ft. Longer trucks must generally reroute east and south into California and then north again to Oregon. That has caused shortage in everything from food to fuel. The slide, named the Curry County Highway 101 Collapse, is about .25 mi. in length with the worst of the movement over about 200 ft., said ODOT spokesman Dan Latham. “The slide cut off underwater channels and that led more water to pool,” Latham said. “When the big rain and snow event started February 24, that’s when we started to see rapid movement. The first night, the slide was moving two feet an hour, resulting in enormous cracks in the road surface. At the south end, the road is completely out of alignment. It’s moved more than 100 feet to the west and has dropped 30 to 40 feet.” While the roadway has historically been unstable, the problems were compounded after wildfires consumed 300 acres of vegetation in recent years. see LANDSLIDE page 10
Crews Protect Boise River Habitat With Winter Clean Up By Lori Tobias CEG CORRESPONDENT
A late start on flood management projects on the Boise River in Idaho had contractors hustling to make the most of their time before the short window of the construction season ends. Work usually begins in January but was held up until February this year due to heavy snowfall in the Boise River mountains and an extensive permitting Flood District #10 photo process. The work was comThe bank-stabilization project also features the pleted the first week of use of bioengineering — log root wads, willow March.

toward repairing damage from “the epic winter” of 2017. “We work as fast as we can in a short window of time when the low-water conditions allow us to make these riverbank repairs,” said Mike Dimmick, district manager of Flood District #10. “We ask the public to honor any closure signs that we put up for safety reasons because heavy equipment will be working in the area. Time is of the essence.” During the winter/spring 2017 flooding event, the Boise River was at flood stage for more than 100 days, said

banks in numerous places, some of which needed to be repaired for public safety and to protect private property.” see RIVER page 10
