Environmental Services has completed replacing a broken culvert under SW Terwilliger Boulevard in spring 2014. A 42-inch corrugated metal pipe carrying stream flow under Terwilliger failed in March 2014. 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.
