The areas evaluated were the same as <br />those examined in previous reports and are shown on Exhibit 1, <br />Sheet 2 of 2 of that report of the 1992 report. As mentioned <br />previously, these areas are not required to be surveyed until after <br />completion of the West Ridge Hydrologic Reconstruction Plan, but <br />are being monitored for background information for use at a later <br />date. The survey results for the three areas are as follows: <br />West Ridoe Subarea SSF Score <br />W-1-TS 34 <br />W-2-NTS 43 <br />W-3-TS 22 <br />Slight <br />Moderate <br />Slight <br />CORRECTIONAL MEASURES AND METHODS SUMMARY <br />Based on the data collected during this 1994 inventory repairing of <br />the feature listed above in Block 1 of the Moffat Area is the only <br />immediate corrective measure planned. Some potential for rill <br />formation exists on the newly retopsoiled area on the Moffat Area <br />but these areas will be seeded this spring and should improve <br />thereafter. Concentrated Flow Feature No. 1 in the South of Shop <br />Area will continue to be monitored for excessive erosion. <br />South of Shop Subarea 3 Erosion Condition <br />Classification <br />Erosion Condition Classification <br />4/19/94 DLB <br />
