Draft Supplemental Environmental Impact Report Page III-30 Forward Inc. Landfill 2014 Expansion Project " The projected total remaining airspace for the Forward Landfill,as of February 2014,was approximately 20.0 million cubic yards(mcy). The proposed expansion would add approximately 8.0 mcy of disposal airspace,which would allow disposal at the Forward Landfill to extend to 2031. While all of the proposed expansion would be Class II landfill space,it is anticipated that Class III waste would be disposed in the expansion areas along with Class II waste. The proposed 2014 Expansion Project would add 8.0 million cy of landfill capacity,compared to the 32 million cy in the previously proposed(2013)project. The projected landfill closure date under the 2014 Expansion Project is 2031,compared to 203913 for the previously proposed project. The 2014 Expansion Project would not entail putrescible waste (waste streams other than -- concrete,rock, asphalt, wood and yard waste)in the Outer Approach and Climbout Areas of the Stockton Metropolitan Airport, expansion of landfilling operations to within 10,000 feet of the end of the runway of the Stockton Metropolitan Airport, or expansion of landfilling operations on to any parcels of land under Williamson Act contract. Relocate South Fork of South Littlejohns Creek To provide further separation of the creek from the landfill,create a contiguous disposal area, and optimize landfill airspace,an approximately 3,000-foot reach of the South Fork of South Littlejohns Creek would be relocated to the eastern and southern boundaries of the landfill(see Figures III.C- 4,III.0-5, and III.0-6). The creek relocation is intended to: (1)provide riparian habitat restoration/ creation, (2)provide adequate flood control (i.e.,to have capacity to carry the 100-year flow within its banks), and(3)provide a stable channel design that meets or exceeds the functions and values of the existing creek. The relocated creek would be 3,200 feet in length. The existing creek traversing the landfill is generally a trapezoidal channel with 10-to 12-foot banks and a 10-to 15- foot bottom width. The channel would be, on average, 60 feet from bank top to bank top. This equates to a 4.13-acre creek zone. The existing creek performs relatively well in terms of flood control14 The existing channel would be moved approximately 1,000 feet to the south to accommodate the further development of the Forward Landfill (see Figures III.0-4,III.0-5,and III.0-6). The ~ proposed relocated channel would be approximately 3,200 feet long and would have greater flood control ability than the existing channel.The new channel would create approximately 8.82 net acres of riparian woodland habitat,bank top to bank top area in a 120-foot wide channel. Constructing the channel would require moving approximately 140,000 cubic yards of material. The creek relocation would use design and construction techniques similar to those used in the successful relocation of the North Branch of the South Fork of South Littlejohns Creek in 2002. During the last stages of landfill development,the proposed new main entrance road would cross the creek channel,using a rail car type bridge spanning both banks. Litter control in the relocated creek would follow established litter control practices at the site. A combination of monitored litter fences,screening, and litter pickers would be used.

However,based on recent disposal tonnage data,2014 estimated closure dates with and without the 2012 (previously proposed)project are 2045 and 2026,respectively.It should be noted that landfill closure wastes being disposed. dates are approximate and can vary greatly based on many factors such as the economy and density of 14 Project Description for Land Use Permit Application,Forward Landfill(Bryan A.Stirrat&Associates,2008). 4
