So what I did here was I took a plan4 A. that the applicant provided and I superimposed some5 arrows to give some direction here. So I want to talk6 about how the wetlands are going to be affected by this7 development. The blue arrows show the direction of8 runoff in the existing condition, so they basically9 travel perpendicular to the contour lines. You can see10 the runoff up here contributes to the wetlands up here11 and so forth. Runoff that runs here runs parallel and12 it feeds a continuos line of wetlands right here. Same13 with over here and over here. They're rerouting -- the14 runoff is spread equally.15 Now --16 Are these -- let me ask you one question.17 Q. The blue arrows, are they reflecting present18 conditions on the site before the development?19 Yes, they're showing present conditions of the20 A. site.21 So now what else is on here is the red arrows.22 The red arrows show how the water that lands on the23 developed area will be rerouted due to the stormwater24 system. So for example, in this section here in the25 26 existing condition the blue point this way. Now the red1 arrows point towards the street. The stormwater runoff2 would be captured by the parking lot, put into the3 stormwater pipes, it will travel down the road and it4 will go into these basins. Same with over here and same5 with over here. So instead of equally distributing the6 runoff to the entire wetlands a large portion -- a7 portion of land runoff that used to go here now is going8 to be rerouted. It's going to avoid these upper9 wetlands and go into this basin and get discharged down10 here. So the drainage for these basins are going -- the11 drainage area for these wetlands are going to change due12 to the development.13 Now, you just referred to the upper wetlands.14 Q. You are referring to the left side of the diagram. Is15 it fair to say that the same would apply to the wetlands16 in the center and on the right side of the diagram?17 Yes, that's true.18 A. Thank you.19 Q. All right. So this is an existing drainage area20 A. map that the applicant provided with their submission.21 What I did is I superimposed rough drainage areas for22 the wetlands and for this point of discharge. It is the23 printout used in their models and I'm trying

plicant provided with their submission.21 What I did is I superimposed rough drainage areas for22 the wetlands and for this point of discharge. It is the23 printout used in their models and I'm trying to24 demonstrate the drainage area that feeds the wetlands25 27 through these area.1 For the record, the area to the left is a dark2 Q. green color, the area to the right is a light green3 color. And obviously if anyone sees the black and white4 version and wanted to define the two color sections.5 This is a newer document with Mr. Walsh's color6 additions superimposed on the document already in the7 record. So some point we should mark this as an8 objectors exhibit, I believe.9 MS. MCGOVERN: We don't have that yet?10 MR. AFRAN: No, we'll have to supply that.11 MS. MCGOVERN: All right. So let's see, we12 are going to call that one O-8, because we already got13 some exhibits from you earlier today. The Princeton14 Hydro report is O-5. CD from his computer is O-6 and15 the color diagram that you sent was O-7. So this will16 be O-8 and we'll call this colorized --17 MR. AFRAN: I suggest we might call it --18 MS. McGOVERN: DA-1.19 MR. AFRAN: Yeah. DA-1. Colorized DA-1.20 MS. MCGOVERN: All right.21 MR. PLOCKER: Could we just make it clear22 for the record, I know you say DA-1, but this is23 something that my client submitted. Could we just get24 clear for the record that this is something that was25 28 colorized by the objectors witness and if we could get a1 date. I just want to make clear for the record that2 this originally was our document.3 MS. MCGOVERN: All right. This is what4 we're going to call it, colorized DA-1 from objector.5 MR. AFRAN: We agree the original document6 was submitted by the applicant.7 MS. MCGOVERN: The colorized version?8 MR. AFRAN: Colorized version --9 MS. MCGOVERN: Yeah. Okay. So DA-1,10 colorized version by the objector.11 MR. AFRAN: Yes.12 MR. KLEIN: Didn't change the shape and size13 of the areas, just colored them in, is that correct?14 THE WITNESS: No, I drew the drainage area15 with the wetlands there. So I drew in that green. I16 didn't colorize it. I used the contours that he had and17 those green areas are drawn by me. Sorry for the18 confusion.19 MR. KLEIN: What was it before you drew that20 on there? What was that drawing.21 MR. AFRAN: It was -- DA-1 as was submitted22 by the applicant. What Mr. Walsh has done is he

rry for the18 confusion.19 MR. KLEIN: What was it before you drew that20 on there? What was that drawing.21 MR. AFRAN: It was -- DA-1 as was submitted22 by the applicant. What Mr. Walsh has done is he used23 the contour lines on the original exhibit to demonstrate24 two drainage areas on the existing site, as shown as25
