Soil Management• Screening of all soil to be re-used or disposed of• Re-use or disposal of excess soil

Utility Corridor and Roadway Relocation Project

Project Start January 2013Anticipated Completion June 2015

Re-use of Excess Soil• Excess soil estimate = 195,000 tons• Current cost to re-use = $0• Current cost to dispose offsite = $100 per ton• Cost avoidance potential = $19.5 million

Additional Benefits of Re-use• Re-use of landfill materials at the source• Site elevation increases to address storm surge

concerns• Avoidance of 6,800 truck trips needed to dispose

195,000 tons of excess soil will reduce vehicle emissions and on-campus traffic related to "to and from" truck trips

Quadrangle) elevations• Storm surge concerns• Views

Screening• Visual screening to identify type of soil based on

composition so that it can be temporarily stored and managed appropriately

• Physical screening of soil that is filled with debris – glass, brick, metal, boulders – these materials represent risks of future settlement

On-Campus Location Options for Physical Screening and/or Temporary Storage• South Lot• Lot A• Lot B• Lot C• Lot D
