  1. Utility Corridor and Roadway Relocation ProjectProject Start January 2013Anticipated Completion June 2015 Soil Management • Screening of all soil to be re-used or disposed of • Re-use or disposal of excess soil

  2. Utility Corridor and Roadway Relocation Project 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

  3. Utility Corridor and Roadway Relocation Project On-Campus Options for Re-use of Excess Soil • Parking Lots • North Parking Lot • Lot D • South Parking Lot • Roadway Areas • Bianculli Boulevard adjacent to Boston College High School • Landscaped Areas/Landforms • Commencement Lawn • Soccer Field and Track • Behind Calf Pasture Pumping Station • Between Calf Pasture Pumping Station and Lot A (Quonset Huts) Site elevations to be determined by: • Adjacent existing or proposed (e.g. Campus Quadrangle) elevations • Storm surge concerns • Views

  4. Utility Corridor and Roadway Relocation Project 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
