Scoby Hill Landslide – Route 219 (Section V) – Springville, NY

Highway construction discovered the presence of a very large ancient landslide within the Cattaraugus Creek valley in western New York State. The active landslide is contained within this ancient landslide complex. The depth of the slide is about 30 m (100 ft). The landslide is 1,000 m (3,300 ft) wide, 500 m (1,600 ft) long and up to 30 m (100 ft) deep. The Route 219 landslide is complex and very expensive to stabilize completely, and therefore a “Balanced Approach” has been developed to best manage slide forces and movements. The landslide was first identified during initial earthwork in 2007. Subsequently, several measures were implemented in late 2007 and during 2008 to slow down the slide movements. The observational approach was used to monitor landslide conditions and to adjust or supplement the mitigation measures. Periodic site reconnaissances were performed to look for other landslide clues and changes in ground distress and relative performance of constructed mitigations. Based on these observations, landslide mitigations were adjusted to minimize long-term highway distress.
