Figure 3 includes original certified design drawings for the silo, for reference. <br /> The silo may be slightly modified from this original drawing to allow better functionality in its new <br /> location. <br /> Layout: The silo will be placed adjacent to the haul road on an elevated,concrete foundation <br /> measuring 18 foot by 18 foot by 5 foot(length,width,depth). A 100 foot by 30 foot(length by <br /> height)retaining wall will be constructed, offset from the silo by approximately 45 feet.
