As a result of the inspection, corrective measures are planned. ' GOAT TRAIL EXIT CHANNELS Transects were measured at the three constructed exit channels along the Goat Trail. The location of these outlets are shown on Exhibit 1, Sheet 2 of 2. The channels were measured across monuments placed in 1993 and compared to evaluate erosion activity. The survey results are shown graphically in Appendix A. Each of the three drainage areas had cross-section ' measurements taken at two locations. Exit Channel 1 ' The cross-sections show that this feature remained stable when compared to the 2001 survey data. Cross-section 2 indicates the feature is relatively stable in this section of the channel with periods of agradation and degradation. No corrective measures planned as a result ' of the inventory. Exit Channel 2 Cross-section 1 shows show that this feature remained stable when compazed to the 2001 monitoring data. The lower section of the channel at cross-section 2 also shows this feature ' remained stable when compared to the 2001 survey data. No corrective measures planned as a result of the inventory. Exit Channel 3 Cross section 1 and cross section 2 both indicate significant agradation when compared to 2001 data. No corrective measures planned as a result of the inventory. w 1' ~C Engineering
