The second option likely would have been the preferred permanent solution to replacing the culvert, which is on Washington Boulevard east of Harrold Street, he told supervisors.Īt a Nov. Olson’s staff report noted that crews left the partially installed liner in place fearing that removing it would lead to further culvert collapse. And probably the preferred alternative, which would have less impact to Washington Boulevard and would be a jack and bore type operation where you would come in with an auger and you’re just pushing the pipe through.” “One is a big dig, which is basically we need to excavate down and just replace the culvert through conventional methods. “My current recommendation, which is different than my staff report, is to still declare an emergency, but to either do two options,” Olson told supervisors. The inspection revealed larger cobbles and more rocks than were previously visible when the water level was higher. Olson said engineering staff had worked with Tidewater Contractors to look at options. A proposed temporary fix to slip line the culvert with a smaller pipe wouldn’t work, he said. Since he submitted his staff report, Olson said a camera inspection of the culvert revealed that about 100 feet of the pipe was gone.
But instead of a temporary fix to keep a culvert underneath Washington Boulevard from collapsing, the county will move forward with a permanent project earlier than anticipated.
