of the larger particles removed) of the soils from the Deepe Farm Pit that 70 percent <br />of the sample was larger than the No. 4 sieve. <br />LEVEE CONDITIONS <br />The levee is a compacted earth structure. Surveys of the levee indicate the <br />steepest slopes are approximately :1 hori ontel:vertieal), the crest width is <br />approximately 1 feet, and the maximum levee section is approximately -feet tell. <br />Based on levee height and slope steepness the critical cross section of the levee <br />is located at Station 124+00. This section is shown in Fig. 7 and was the focus of <br />ge teehni al evaluation. Seepage, slope stability, and consolidation analyses of <br />the levee are presented below. <br />The maintenance work done during reclamation of the gravel pit was recently <br />completed. This maintenance was done after the geotechnioal exploration. The <br />levee slopes are free of trees and brush (see Appendix 13). <br />Part of the maintenance during the reclamation of the Deepe Farm Pit <br />included minor grading to finally shape the levee crest and slopes to the desired <br />configuration. CTUThompson, Inc. observed and tested the embankment fill placed <br />during the maintenance work (see Appendix . <br />At locations just beyond the land side tee of the levee water was seeping <br />from the ground but was not affecting the structural integrity of the levee. There <br />was no evidence of piping (movement of fines from the ground under the levee <br />through the seeps). The locations of seeps apparent in arid - urnmer of 1 were <br />surveyed by Scott, Cox and Associates. The results of that surveying are in <br />Appendix C. The seeps that were apparent in the fall at approximately stations 112 <br />+ 00, 124 + 00 and 126 + 00 just beyond the land side toe of the levee were covered <br />with a geofabric and covered with sand and gravel. <br />FLATIRON COMPANIES <br />LEVEE AT DEEPE FARM PIS' <br />CTUT 25t3B5 <br />
