Cityof Quesnel 4 Kinchant Street Quesnel, BC V2J 7J5. amecc!} Dear Mr.Jack Marsh, Director of Public Works RE: NOVEMBER SLOPE NCLNOMETER NSTAllATON READNGS WEST QUESNEl STABLTY STUDY 1. NTRODUCTON This purpose of this letter is to provide the City of Quesnel (CoQ) with an update on slope inclinometer (S) monitoring in West Quesnel. Since installation and initial survey of the seven S installations in the late fall of, AMEC has conducted subsequent readings of each S (except S-4 and S 5 where 11 sets of readings have been conducted). The latest set of readings was conducted on November 19, 2. At that time three more of the installations (S-3, S-4, and S-7) were determined to be blocked or sheared at depths corresponding with the previously detected slip surface locations. S-6 had been previously determined to be blocked in a similar manner during May 2. At present the only remaining fully functional installations are S-1, S-2, and S-5. S-7 had two slip surfaces detected in it, and was found to be blocked at the lower one. t is therefore still possible to monitor relative movement above and below the upper failure surface in S-7. The remainder of this letter further describes slope inclinometer measurements to date. 2.

The S readings are presented in incremental and cumulative plots with a 75 mm and mm horizontal displacement scale versus depth. The incremental plots show the individual changes in inclination of the casing at each reading elevation. The cumulative plots are constructed by adding together the incremental changes starting from the bottom of the installation and show the overall apparent movement of the S casing at each elevation relative to the bottom of the casing. Two channels of readings are presented: A and B. The A channel is oriented to be "down slope" whereas the 8 channel is "across slope". The actual orientation of each of the casings is shown on previously supplied mapping. Positive movements on the cumulative plots are down slope on Channel A and across the slope to the right when looking downhill for Channel 8. Table 2 presents AMEC's observations based on the data gathered to date.

The following notes should be read while reviewing the S data presented in Appendix A:.. A second set of plots for S-5 has been included with the readings previous to 3 Apri 1 omitted to eliminate the wave like profile observed in the raw data. This plot ma) present a clearer representation of how much of the. S deformation may be attributable to lateral ground movement, as opposed to vertical compression of the casing.. A second set of plots has been included for S-7 for the 'portion of the borehole above 68 m which can be still monitored. 4. FUTURE WORK Given the nature of the movements observed to date, AMEC recommends continued monitoring of the operable S installations, with the next set of readings being conducted in the early spring of 3. Given that the majority of S's have been sheared in the Uplands Area, AMEC suggests that an additional S installation be installed either at Voyageur School or in the central portionof the studyarea. Note that any new S should be installed to a depth of at least m past the previously recorded lowest slip surface, rather than the full depth of the original installation. This installation,would replace one of the 6 new installations recommended in AMEC's final report of 25 October, 2.'. 5. CLOSURE Thank you for the opportunity to provide assistance in this matter.
