Forest Home Drive Retaining Wall Repair 

Ithaca, NY

Kris Burnham, PE, Russel Lutch, PE - Brierley Associates

Mike Palmer, PhD, PE, Joe Caza, PE - Elwyn and Palmer, Consulting Engineers, PLLC

 

Located in the heart of the Fingerlakes Region of Upstate New York, Ithaca is the home to scenic gorges and waterways as well as Ithaca College and Cornell University. Fall Creek Gorge and Triphammer Falls, a 55-ft cascading waterfall, pass through the center of the Cornell University campus. Forest Home Drive is located along the top of the gorge and in places is supported by a retaining wall. Near the base of the tallest section of the retaining wall, an approximately 14-ft high section of the masonry facing had collapsed allowing soil erosion and causing settlement of the roadway and sidewalk above the wall. In addition to the partial facing collapse, bulging of the facing near the base of the wall was observed.  In response to the wall facing collapse and subsequent settlement, the roadway was closed to vehicle and pedestrian traffic, significantly effecting travel between the surrounding campus facilities.

Alternative Delivery Models for Water Infrastructure 

 

As municipalities and owner/operators of public utilities look for ways to design/finance and construct aging water related infrastructure, alternative project delivery models such as Design/Build and P3 are being further examined. United States Environmental Protection Agency (USEPA) Water Infrastructure and Resiliency Finance Center sponsored and underwrote the University of North Carolina Environmental Finance Center to perform an in-depth examination of nine projects where communities used Alternative Delivery Models for water sector projects. USEPA published a companion article Perspective: "The Financial Impact of Alternative Water Project Delivery Models" in the Water Sector.
