For footings placed at thc top of cut or fill slopes, provide a minimum three foot set beck <br /> at the ground line. Footing selback should meet the requiremrnts of IBC 2003 Sa�tio�.i <br /> I805, Figure 1805.3.1. <br /> 4. Footings should be proportioned to meet the stated bearing capacity and/or the IBC 2003 <br /> minimum requirements. [nterior or isolated column footing should be a minimum of 24" <br /> wide. Continuous strip footings should be a minimum of 16"wide. <br /> 5. Isolated exterior end perimeter footings should be buried a minimum of 18 inches; <br /> interior footings should be buried a minimum of 12 inches. <br /> 6. In order to minimize the efFccts of any slight diffemntial movement that may occur due to <br /> variations in the chaiacters of the supponing soils and seavonel moisturc contrnts, we <br /> recommend that all footings be suitably�einforced to meke them as rigid as possible. <br /> 7. Total settlement oF footings instelled as recommended ebove wiil be limited to 1 inch <br /> with differential scttlement limited to'/.inch. <br /> 8. Footing drains should be used to displace scesonal water from the bearing soil level. The <br /> drains should consist uf 4" diemeter perforated pipe, surrounded by drain rock, wrapped <br /> in a filter geotextile and havinq a sufficient gradient to displace water away from the <br /> structure end directed to en eppropriate outfall as shown in the footing drain details, <br /> atteched. Roof or other storm drains should not outfall into the footing drains. <br /> 8_3 ��'b <br /> a <br />
