Abstract
The Seneca Meadows Landfill in central New York is the largest municipal solid waste landfill in the state. It is situated in extremely challenging soil conditions that have caused a history of stability problems at the facility. Following two major slope failures during construction in the early 2000’s the facility decided to try a different approach to develop stable landfill cells. Todd will discuss the site history and geologic setting of the facility, and how his firm assembled a massive amount of data into a model to characterize the subsurface conditions. He will describe how the model was used to design a ground improvement program to allow for the berms and excavations to be constructed while meeting the required factors of safety. Jon will conclude the discussion talking about the construction methods, assessment techniques, and lessons learned from the last few years.
Todd graduated from the University of Cincinnati in 1998 with his Bachelor of Science in Civil Engineering and from the University of Michigan in 1999 with his Master of Science in Civil Engineering with a geotechnical engineering focus. Following his graduation, he joined McMahon & Mann Consulting Engineers, P.C. (MMCE), a geotechnical engineering consulting firm located in Buffalo. Todd became a principal in the firm in 2014. He has worked on a wide variety of geo-design projects, mostly in the Midwest and Northeast. His focus has been in slope stabilization, excavation support design, creek stabilization, and dam engineering.
Jon graduated from the State University of New York at Buffalo (UB) in 2015 with Bachelors of Science in Civil Engineering with a focus on geotechnical and structural engineering. He joined MMCE after receiving his degree. His focus with MMCE has been on subsurface exploration and characterization, geo-structural projects, construction monitoring, and slope stabilization. Prior to graduating from UB, Jon spent 15 years working in construction related fields.
