� I I � � I in thie way, the adequacy of the earthwork may be evaluated as filling progreseee and any problem areae may be corrected at that time. � 8.0 FOUNDATIONB Due to the presence of up to 8 feet of uneuitable fill, a deepened foundation syetem will be necessary for building eupport in eo�e areae , especially in the central portion of the aite. 3everal optione are available for foundation support and more than one option may be neceseary for conatruction of the development depending on the finieh floor elevatione for the building. Theae opticne are deacribed below and include 1) apread footinge and extended footinge; 2) concrete or rock trenches ; or 3) drilled piera. 8_1 9pread Footinoe In areas where the bearinq atratum is relatively ahallow, epread footings may be uaed for building eiipport When founded on medium dense or dense, natural, in-place aedimente. An allowable bearinq preseure of 2, 500 pounde per square foot (psf) , including both dead and live loade , may be utilized for deeign purposes on the medium denae ablation depoeita (Unit 31 , and lodgement till (Unit 2) . An increase of one-third may be ueed for ehort-term wind or seiemic loading. Perimeter footings ehould be buried at least 18 inches into the surrounding eoil for froat protection. Interior footinge need only extend 12 inchea below adjacent qrade . However, all footinge muet penetrate to the preacribed bearing etratum and no footing ahould be founded in or above loose, organic, or exieting fill soils. In addition, all footinqe ahould have a minimun width of 18 inchea. Anticipated aettlement of footinge founded on the medium denee or dense aedimenta should be on the order of 1 inch . However, diaturbed soil not removed from footing excavations prior to footing placement could result in increased eettlemente. all footing areae ahould be inepected by Asaociated Earth Sciences , Inc. prior to placing concrete to verify that the bearing eoils are undiaturbed and consiatent with the recommendatione contained in thie report. Such inapectione may be required by the governing municipality. Perimeter footing draine ehould be provided ae discuased under section 9.0, Drainage Consideratione. 8_2 Concrete or Rock Trenchee in the more central portione of the aite where the fill appeare to be thicker (up to B feet encountered thickneesl , alternative fouc,datian deaigne may be more coat effective. Two of the more commun rt:ethode are lean mix concrete or rock trenches. If the lean mix concrete option is chosen, the excavation ehould have a minimal width equal to the proposed footinq width and the concrete should be a minimum 2-1/2 eack mix. Due to the potential for cavinq, the 8 �(y
