The closure of Redwood Drive between Redway and Dean Creek is being worked on and is expected to be lifted this week.
Tony Seghetti, the county’s Deputy Director of Public Works for engineering, said rain events that began the week of Jan. 18 led to the depositing of “some minor slide debris” on the road but that was followed by the failure of a three-foot-diameter culvert.
The embankment on the outlet side of the culvert washed out, he continued, and a sinkhole developed on the culvert’s inlet side, in the northbound lane of the road.
Work being done under an emergency repair contract started on Jan. 25 and was suspended when heavy rain returned later that week. But Seghetti said the situation is being monitored and weather permitting, work is expected to be completed by Feb. 3.
The project will involve installing a new culvert and rock slide protection on both sides of it.
It’s estimated to cost a maximum of $40,000. Seghetti said that although the county is paying for it, damages countywide could lead to an emergency declaration and potential federal funding.
