The report shall include a <br />description of any appearances of instability, structural weakness, and other hazardous <br />conditions. <br />The inspection was conducted on December 19, 2013. The Division received the report on <br />December 23, 2013. No instability, structural weakness, or other hazardous conditions were <br />noted during this inspection of the fill. It was noted in the report that the cracks noticed on the <br />top south portion of the fill during the first quarter were sealed and that no additional cracking <br />was observed. Also, two spots above the 7350' elevation level on the south side of the fill <br />showed some additional signs of differential settling. However, there were not any signs of <br />bulging at the tow or any cracking. Monitoring will need to continue in these areas. <br />If you have any questions feel free to contact me.
