Is there11 grouting those cracks, is that inspected by some neutral12 person or does the foundation work begin?13 The treatment of the rock is completed and then14 A. the foundation would begin.15 So no inspectors actually going to know to what16 Q. extent grouting was actually done because the foundation17 will go on top of it before any inspector sees it, isn't18 that true?19 No, you inspect the rock before you pour the20 A. concrete.21 I just asked whether or not there's an inspector22 Q. who's going to examine the grouting before the23 foundation is poured?24 Okay. I didn't understand.25 A. 34 Okay.1 Q. Yes. There is. There would be an inspector.2 A. Now, there could be thousands of potential cracks3 Q. to be grouted, right?4 Right.5 A. And this is a 800 hundred foot long by 200-foot6 Q. excavation going down 25 feet, right?7 Right.8 A. Now, if cracks are not filled and ultimately9 Q. filled with water that's what causes destabilization, is10 that correct?11 Well, where did the water come from?12 A. Why are you raising it in the first place?13 Q. So that the water is controlled, that's why we14 A. recommended that they look at the infiltration basins,15 so that they don't introduce water, otherwise there's --16 we're not sure there's even groundwater there.17 And you haven't had a confirmation on that issue?18 Q. Sorry?19 A. You haven't had confirmation yet on that issue?20 Q. On what issue?21 A. The examination of the infiltration basins.22 Q. No, I said that.23 A. Okay. I wanted to clarify. Thank you.24 Q. Now, let me get back to this page. We touched on25 35 this last week, the toe of the slope is the area that1 flattens out underneath the slope so the slope an maybe2 the toe comes here?3 Correct.4 A. Okay.5 Q. Now, would you agree in this particular site the6 slope on the building or next to the building, near just7 above the toe of the slope

o the slope an maybe2 the toe comes here?3 Correct.4 A. Okay.5 Q. Now, would you agree in this particular site the6 slope on the building or next to the building, near just7 above the toe of the slope not on the applicants8 property, but actually on the private homes that are9 behind the slope?10 There is a break in the slope, the slope flattens11 A. about halfway down the slope and then the toe of the12 slope would be down near the road where the houses are13 on the lower roadway.14 So the toe of the slope is actually on private15 Q. property, right?16 It goes right to the street probably.17 A. Okay.18 Q. So it's on their houses?19 Right.20 A. It's on their land. So the toe of the slope, to21 Q. clarify, is on the private homeowners land, right?22 I am not sure that's the final toe. There's23 A. another couple 100 feet to the main road, so.24 Well, if --25 Q. 36 The slope may continue beyond what's shown on the1 A. drawings. I didn't investigate that.2 Okay.3 Q. Well, let me ask you, in the catchment area it4 refers to the area of toe of the slope that is designed5 to catch rocks and overburden and other things that may6 come down the slope, isn't that correct?7 I don't know what that is.8 A. You don't where the catchment area is?9 Q. No.10 A. Well, it's actually in the townships steep slopes11 Q. ordinance that refers to catchment areas being --12 If you're talking about the slope where there's13 A. rock fall, which is not the case here, then you need an14 area to contain the rock fall, if that's what you mean,15 then that's what it is.16 Well, if there is no rock fall seen presently17 Q. you're saying -- you're saying you haven't observed rock18 fall presently?19 There's only small outcrops roughly 10-feet high.20 A. Well, if the ridge is destabilized by blasting21 Q. then isn't there a much greater likely of rock fall?22 Well, the blasting charges should be limited so23 A. it wouldn't be destabilized.24 If mistakes are made or good planning is not25 Q.
