The site was inspected and appeared to be stable,but had not yet been repaired. It appeared <br /> that the slump was related to water leaking from a joint in culvert C5E-25 (formerly C2-3A). The culvert had been <br /> temporarily replaced with a shorter culvert running directly down the fall line of the slope. It was agreed that if <br /> this is to become a permanent solution a revision will be needed,with revised designs for the downstream <br /> structures. <br /> DOCUMENTS RECEIVED <br /> N/A <br /> OTHER(SPECIFY) <br /> N/A <br /> ENFORCEMENT ACTIONS/COMPLIANCE <br /> No enforcement actions were initiated as a result of this inspection,nor are any pending. <br /> Number of Partial Inspection this Fiscal Year: 6 <br /> Number of Complete Inspections this Fiscal Year: 3 <br /> Page 3 of 9 <br />
