SW Terwilliger Emergency Repair

culvert repairEmergency Culvert Repair Project

April 2014

Environmental Services has completed replacing a broken culvert under SW Terwilliger Boulevard just south of SW Bancroft Terrace and repairing erosion damage to the hillside. The city will revegetate the site this summer.

A 42-inch corrugated metal pipe carrying stream flow under Terwilliger failed in early March. On the hillside below Terwilliger Boulevard, flow from the broken pipe scoured out an area about 25 feet deep, 20 feet wide and 70 feet long. Maintenance crews had to remove a large maple tree that was undercut by the erosion.
