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 March 26, 2014. The Division received the report on March <br />31, 2014. No instability, structural weakness, or other hazardous conditions were noted during <br />this inspection of the fill. It was noted in the report that the cracks noticed on the top south <br />portion of the fill during the first quarter were sealed and that no additional cracking was <br />observed. Also, two spots above the 7350' elevation level on the south side of the fill showed <br />some additional signs of differential settling. However, there were not any signs of bulging at the <br />tow or any cracking. Monitoring will need to continue in these areas. <br />If you have any questions feel free to contact me.
