3 Secondly, the area shown near the Lydia/Snelling location, generally called Area D, now has at the other end of this pipe that crosses Snelling, ponding area near Snelling and also the Northwestern College to provide ponding to service this area. That's also new and was completed this summer. The second reason for reviewing this storm drain is because petitions have been received by the City and are also pending for streets within this boundary area. It is the staff's position, and I would say generally well held and (inaudible)with other engineers, that you do not put streets in and come along three years later, tear the streets up and put a storm drain in. Not only is it totally destructive to the street and a waste of funds, but also by building streets without having proper drainage the streets simply will not hold up at (inaudible). The drains are to carry the water away from the street rather than have them set along the edge of streets or ditches and inundate the ground under the pavement, so the City has received petitions. As a result of that it's necessary to look at providing the storm drains for those areas, and those petitions crossed and include most of the boundaries. They would include A, B, D, pieces of A again, and C, so through one petition or another nearly a whole area is affected. Therefore, we looked at the whole area for storm drainage. Lastly, and I guess I would say not leastly, we continue to get complaints from some of the parcels in the area that they're simply not having adequate drainage. Of particular concern is the swale and ditch way off the end of the Brenner cul-de-sac which every year causes flooding in the cul-de-sac, and I would say without proper drainage facilities that's something we cannot control. There's also standing water in these areas and standing water in most of the quadrants of the intersections in the area because they are somewhat lower and have no facilities to carry them out. The roadways are constructed in a normal manner with a crown in the middle and when you have a crown this way and that, until the water builds up enough to get over the crown you have standing water. That is sort of a brief breakdown as to why we are now looking at these facilities. There are various locations throughout here that we feel should have storm drainage facilitiesprovided as well as to maintain, as best we can, the roadway system. In a few minutes Mr. Popovich will be talking to you about the cost involved as well as assessments. I'd jU3tlike to at least have you keep in mind that the costs he's going to be discussing assume that there are no roadways to be done at the same time the storm is being done. We have to make assessments for the particular improvement. We cannot assume some street will be paved or some other street will be paved. We have to make estimates for what it would cost to put the storm drains in and then repave the street behind us (inaudible). .temporary pavement but it still costs mmney. Simply reconstructing Lydia back to its current status is approximately $8'6,000 if done with the storm work. Also the other petitions, if they were done at the same time the storm work were done would be another $70,000 that
