West Ridge has been separated into nine different blocks for the Erosion Inventory Control Report using the terraces ' as boundaries (see Exhibit 1, Sheet 2). Table 12 provides a summary of the inventory data and is followed by a brief description of each block and corrective measures performed on each block as a result of previous inventories. P&M personnel expect that some erosional features may ' develop in the newly reclaimed areas for the next several yeazs until vegetation begins to establish. The terraces are performing as anticipated; existing gullies located primarily on older non-topsoiled reclamation show no sign of activity and seem to be stabilizing with vegetation establishing along the sides and bottoms. Most blocks showed slight improvements over the previous yeaz. Block 8-9 showed some deterioration due to the formation of a flow pattern south of the road. Ice dams blocked spring snowmelt in several places resulting in terraces overtopping and forming gullies. The reduced status was primazily caused by the slow establishment of vegetation on the most recently reclaimed non-topsoiled portions of the blocks.
