97 <br /> Tim Smith: It would be bigger SCMs, more disturbance area. We're trying to do low impact, minimize our <br /> disturbance, minimize our impervious areas. We would have to cut more trees and make a bigger space to provide <br /> that control. <br /> Patricia Roberts: If you have a lot of pervious ground,then you are not going to need as much as you think. You've <br /> got the natural way for water to be a absorbed into the ground and you're just trying to take over probably what you <br /> have made impervious. The tradeoff, I would rather have more trees. <br /> Tim Smith: With the one inch,they also call it water quality also. They call it the first flush. That first hard one inch <br /> of rain hits all the pavement areas where all the nasty stuff is and that's what runs off first and that's what we're <br /> required to treat first for nutrients and water quality. <br /> Kim Piracci: Is the impervious, pervious areas taken into consideration when you decide how much? <br /> Tim Smith: the project as a whole,we're very low on total amount of impervious. The allowed maximum for this <br /> property is 36 percent and we're only proposing about 17 percent. <br /> Kim Piracci: What would happen if you made 15 units instead of 20;would you then still have the cut down as many <br /> trees? <br /> Tim Smith: Potentially not, but that's all a balance of everything else we've talked about. <br /> Patrick Mallett: The way this typically works for a single-family residential subdivision is it's a bit of a calculated right <br /> sizing in terms of runoff and stormwater. Looking back at the layout. You want to put your open space and the <br /> devices in the right place and then routing stormwater that would go through ditches into pipes. A big part of their <br /> design and a analysis is to locate them in the right place, right size them, and assume that they built it and designed <br /> it and located it appropriate for the initial clearing,the initial impervious to carry the freight for the public roads, and <br /> then assume a theoretical clearing and an impervious amount for each of the lots. Part of the analysis is to factor in <br /> the impervious water quality,water quantity and then the rate of runoff. <br /> Jim Ray: My name is Jim Ray. I'm Occoneechee Golf Club. We were the ones going to get the water. I just want <br /> to ask Tim how much more water are we actually going to get then we're getting now? If you can get the state to <br /> build a culvert the first one west of where you all going to build, that would solve a whole lot of our problem. <br /> Tim Smith: It's hard to say. The intent is always in following the guidelines that we have the follow. To keep it <br /> basically as it was before the development was there. <br /> Jim Ray: That's too much. <br /> Tim Smith: The numbers that we are required to adhere to are no more post development than predevelopment. <br /> Jim Ray: I'm not against the development, but I would like to have as much help as we can to stop the water. <br /> The left turn lane, how much more pavement is going on our side of the road and where is the ditch line going to be <br /> then? <br /> Tim Smith: We don't have the final design. We're doing a proposed symmetrical widening. On your side right now, <br /> the pavement will get about three feet wider than where it is right now. If it looks like it's going to be a problem on <br /> your side of the road,we can shift the widening to be more on the project side with less impact on your side so we're <br /> not having to push ditches and that sort of thing. <br /> Jim Ray: We don't need to lose anymore property. <br /> Tim Smith: Everything we do has to be within DOT's right of way. It's not going to be on your property. Hearing your <br /> concern,we want to keep everything we can away from you. <br />
