West Ridge has been <br />separated into nine different blocks for the Erosion Inventory Control Report using the terraces <br />as boundaries (see Exhibit 1, Sheet 2). Table 12 provides a summary of the inventory data and is <br />' followed by a brief description of each block and corrective measures performed on each block <br />as a result of previous inventories. P&M personnel expect that some erosional features may <br />develop in the newly reclaimed areas for the next several years until vegetation begins to <br />establish. The terraces are performing as anticipated; existing gullies located primarily on older <br />non-topsoiled reclamation show no sign of activity and seem to be stabilizing with vegetation <br />establishing along the sides and bottoms. Most blocks showed slight improvements over the <br />' previous year. The reduced status was primarily caused by the slow establishment of vegetation <br />on the most recently reclaimed non-topsoiled portions of the blocks.In addition, the winter of <br />2001-2002 was very mild with low precipitation and little runoff. This permitted 2001 repairs to <br />' establish vegetation and vegetation in stable rills and gullies to become better established. Some <br />rills and gullies in Blocks 1- 6, 12-li, and 13-14 will be repaired in 2002. <br />Table 12: West Ridge Erosion Inventory Data Summary <br />Area 2002 2001 2000 1999 1998 1997 1996 <br />Block 1-6 Il Il 11 12 13 35 18 <br />Block 6-7 14 14 17 18 18 21 18 <br />Block 7-8 11 13 22 24 23 17 I7 <br />Block 8-9 17 22 27 12 7 IS 19 <br />Block 9-10 13 13 19 18 12 27 25 <br />Block 10-11 12 12 14 18 12 23 24 <br />Block II-12 7 7 8 18 12 19 22 <br />Block 12-13 7 7 9 12 12 21 21 <br />Block 13-14 6 6 6 9 6 24 26 <br />w <br />9 WC Engineering <br />
