Mr. Ojdrovic, a professional engineer, said that the Town had installed water, sewer and gas service in the road and paved and patched the road. He explained that he would be seeking a waiver of the circular turnaround but that he had designed a hammerhead that could accommodate a 30' by 8' vehicle. He was also considering requesting a waiver to allow the paved roadway to be installed to the southern side of the right of way, rather than being centered. This would require less cut and fill, as well as more room for the proposed swale and drainage system. As to improvements to the existing portion of Clelland, Mr. Ojdrovic said there was physically no room for an 18' road without an 8' to 10` retaining wall on the downhill side. He was proposing to widen the portion near Lizbeth to 14- 16', from 11- 12'. He also felt that curbing would impede drainage into the swale. Moving the pavement to one sideline would allow 9' for drainage structures. Mr. Kastorf asked if drainage would be handled through an open swale running the length of the street, and Mr. Ojdrovic said he hasn't completed the calculations yet, but he felt that he may need underground recharge structures as well. Mr. Kastorf asked if all of Clelland would drain toward Lizbeth, and was told that there was a crest at the light pole and Lizbeth would only receive runoff from the road between Lizbeth and the crest. Mr. Ojdrovic added that if he widened the pavement 2', the increase in runoff to Massachusetts Avenue would be minimal, less than 11100 of a cubic foot per second. Ms. Chase asked about stonewalls she had seen in the vicinity of the property. Mr. Ojdrovic pointed them out on the map and said they would remain. Mr. Galaitsis asked how would he cope with the slope requirements. Mr. Ojdrovic said that he would be below the maximums on the new portion of Clelland, the existing portion was 12 percent, and Lizbeth was from 15 to 16 percent and there was not much he could do about it. Mr. Davies commented that roads didn't get .much worse than Lizbeth. Mr. Harden said he felt that the most pressing drainage issue is the result of building on the lower lot, and asked how that would be handled. Mr. Ojdrovic said that both houses would have drywells for roof drainage; retaining water from the uphill lot would result in less runoff on the lower lot. In test pits, refusal had been at 9 to 11' and the soil was primarily sand and gravel topped with a foot of loam. When asked if this had been reviewed by other departments, Ms. McCall- Taylor said that Deputy Chief Bill Middlemiss of the Fire Department had looked at it. As a result the turnaround had been changed to be somewhat larger, but there were still concerns about the intersection of Lizbeth and Clelland. There ensued a discussion of turnarounds and their design with the board wanting to make sure that any proposed turnaround would meet with the approval of the fire department. Mr. Harden said that the biggest concern is the width and turning radius at the intersection. He wondered if the retaining wall could be raised to allow widening the pavement for the first 5 to 6 feet of Clelland. Mr. Ojdrovic said that there are already tire tracks in that area indicating it was used and he would look into incorporating it into
