Geomorphic studies of landslides in the Tully Valley, New York: implications for public policy and planning

On April 27, 1993, a large landslide in the Tully Valley, Onondaga County, NY, destroyed three houses and resulted in the evacuation of four others; it also triggered a loss of potable drinking water for about 15 homes north of the slide area and affected a total of 20 ha of land. In the 7 years following this slide, several studies have been conducted by federal and state environmental agencies and by local universities. The goal of these investigations has been to determine what caused this slide, document the history of past landslides in the region, and establish whether future slides are likely to occur. This paper reports on the results of these investigations and examines their effect on the Tully Valley community. [Copyright &y& Elsevier]
