~,',L SLOPE STRBILITY MONITORING PLAN <br />In o-rder to monitor the stability of reclaimed slopes monuments will be <br />placed-and monitored according to the following plan. <br />The monuments w711 be constructed as shown in Figure 1. Each monument <br />will consist of a smooth metal pin 1 to 1 1/2 inches in diameter and 7 <br />feet in length. The pin is to be buried in the ground to a depth of 7 <br />feet. If rocK is encountered at-a depth of less than 7 feet the rocK <br />fs to be drilled for a depth of not less than 1 foot and the pin resin <br />grouted into the rocK. R plastic pipe 2 to 2 1/2 inches in diameter <br />and 6 feet in length~is placed around the pin with the top of the pipe <br />flush with the top of the pin. The void between the pin an-d the pipe <br />is filled with dry sand or soil. A cap to Keep out moisture. is placed <br />over the pipe. The monument can be placed flush with the ground, <br />counter sunK or placed as shown in Figure 1 depending on the amount and <br />type of traffic in the area. In all cases the monuments are to be <br />• staKed and well flagged. <br />MO IM NT pI.A - M NT <br />The monuments are to be placed !n sets of two as shown in Figure 2. <br />The first monument of each set is to be placed in the rim or top of the <br />slope fill area. The second monument in each set is placed in the toe <br />or bottom of the slope fill area. The exact placement will be <br />determined by the supervising engineer at the time of reclamation. <br />These monument sets are to be placed along the slope fill on 7~r to 100 <br />feet centers. Again the exact placement will be. determined by the <br />supervising engineer at the time of reclamation. <br />SLOPE,~A~'ifJ7 TOR ING <br />R-survey of the monuments is to be performed annually to detect <br />horizontal and/or vertical movement. This survey is to be certified by <br />either a registered land surveyor or professional engineer. 'In <br />addition to the survey the reclaimed slopes are to be inspected <br />annually by a professional engineer and certified as to the stability <br />of the slopes. <br />/v1-45 R ~~//~/ <br />
