March 31, 2008 Mr. Paui Tessier L&A Job No. 8A027 Page 8 The above recommended cut slopes are under the assumption that groundwater seepage would not be encountercd during construction. [f groundwater seepage is encountered, the construction should be immediately halted and the slope stability re-evaluated. The cut slopes may have to be flattened and other measures taken to stabilize the slopes. Surface runoff'should not be allowed to ilow uncontrolled over the top of cut slopes. Cut slopes should be covered with plastic tarps, as required, to protect them from erosion by stormwatcr. STRUCTURAL FILL Structural fill is thc fill that support structural or traffic load. Structural fill should consist of clean soils with particles not larger than four inches and should be frce oF organic and other deleterious substanccs. Structural fill should have a moisture content within one percent of its optimum moisture content at thc time of placcment. The optimum moisture content is the water content in the soil that enablc the soil to be compacted to lhe highest dry density for a given compaction efi'ort. The on-site cican till soils may be used for structural fill only under fuir weather conditions when their moisture content can be controlled to near optimum moisture content at thc time ot placement. Imported material to be used as structural fill, should be clean, frec-draining, granular soils containing no more than 5 percent by weight finer than the No. 200 sicve based on thc frsction of thc material passing No. 4 sieve, and should have individual particics �wt I�vgcr than luur inchcs. Fill embankmcnts placed over arcas stecper than 15% grade should be structurally supported. The ground ovcr which structural till is to be placed should be prcpared in acwrdance with rccommendations in the Site Y�aration and General Gradine and Excavation Slopes sections of this report. Strucwral lill should bc placcd in IiRs no more than 10 inches thick in its loose state, LIU & ASSOCIATES, INC. �- ,
