In this way, the only possible contact <br /> with water would be direct iainfall on tho refuse itself. Since this <br /> area is subject to ocassional intense storms, but not large quantities <br />i <br />of rainfall, these dikes need not be more than a foot to a foot and <br /> a half in height, eo long as they allow sufficient cover area to aontai <br /> the maximum known rainfall. <br /> A study of tho Surmiary Sheet concerning precipitati <br /> and flood flow indicates that if the land fill site is maintained at an <br />elevation of 17 ft. above Brackett Creek, it will not be endangered by <br />flooding. Tha area could be diked along the north and eastern <br />lines in such a way as to allow deeper excavation without danger of <br />flooding. If this is done, the top of the dikes should be kept at an <br />elevation of 12 to 15 ft. above the flow line of Brackett Creek at <br /> <br />~ particular point. <br /> Since the groundwater table was noted in Test Sorir. <br />~~ <br />i 4 and 3 at the northeast corner of the site, these areas should not be <br />i <br />•~ <br />deeply cut <br />or used <br />ae land fill disposal sites, if clay lenses are <br />~ found in the site, these clays should ba stockpiled and compacted et th <br />j~ bottom of the fill excavation in tho northeastern portion of the sits. <br />~~ in this wny, the debris in th® land fill can ba sealed from the direct <br />l0 <br />
