And as far as the detention ponds, in terms of the new design, numbers five and six, they've been designed to basically hold the peak rates and contain that flow so it doesn't add to any of the peak rates which are entering the parcel which would eventually go to the culvert. So from a peak rate standpoint, we're fine. I think when we get the written documentation in, the specific questions, we'll have our team take another look at it, but I'm basing on what we know of that project and what we've done to date, we think the peak rates are checked because of the two new detention ponds which -- five and six, as you mentioned, which are part of the Whittier project. MR. SABREAVY: Do they take care of fallen trees and so forth that fall across the brook and impede the flow The area needs to be cleaned up in that culvert area and I wonder if your hydraulic studies don't take that consideration into play In other words, you can check the plant growth and the tree growth and all that particular stuff, but you really should be considering some obstructions along the way in the brooks. MR. BERTOULIS: You know, I'm not the person running the model but I had a brief discussion with ATM, Inc 339-674-9100

Now, trees falling over brooks and private property, whatever, elsewhere, there's no way to model those types. That's just general maintenance that needs to take place of the drainage shed by the actual owners and elements of it. But you know, get us in your written comments and, you know, we'll make sure that we address them and go back and double check some things in terms of our responses. MR. SABREAVY: Thank you very much. MR. BERTOULIS: Thank you for your question. MR. RUDOLPH: Bill Rudolph, Amesbury, Mass. I live on Deer Island. And my first question is can you tell me how much closer the north span of this new bridge is going to come to the island or how wide it's going to be aside of what is there now We're thinking of the sound. And I realize sound barriers can't be put on the bridge but we've got a lot of noise now and we want to know how much we're more we're going to be getting. MR. BERTOULIS: The one thing, is it's a 60 year-old bridge and they there have been problems on ATM, Inc 339-674-9100
