Based on this survey,it appears that it will be difficult to <br /> place the sewer line the right of way for Old Barnstable Road and Route 151 as discussed previously., <br /> First,the layout for Old Barnstable Road is narrow,and is not much wider than the paved surface of the <br /> road.. To stay in the layout of the road,the sewer will have to be below the paved portion of the road. <br /> In fact it will have to run on the opposite side of the road to avoid the water line on the eastern side of <br /> the road. This increases the complexity and cost of the construction and makes it more difficult for the <br /> Town to develop additional sewer connections in the future. On Route 151,there is a 12 in,gas main on <br /> the same side of the road where we would like to put the sewer line. To avoid the gas line safely <br /> (staying about 10 feet away),we need to be on the High School property instead of in the road layout. <br /> The sewer could run just inside the property line,leaving a vegetated buffer between it and Route 151. <br /> Our engineers have had preliminary conversations with National Grid regarding the gas main,and they <br /> have expressed concerns about construction in proximity to this line. <br /> I wanted to bring these issues to your attention and see if keeping the sewer line on the High School <br /> property is acceptable to the town. I think it avoids construction issues now,and provides the Town <br /> greater flexibility for future connections as well. <br /> Andrew Singer,the attorney representing HAC for the Breezy Acres project has submitted a draft <br /> wastewater agreement. This draft included a plan showing the sewer line in the road right of way, <br /> completed prior to our recent survey. A revised plan showing the survey and utility data,and the line on <br /> the High School property is attached here. <br /> Thank you for looking this over and please let us know if you have any questions. <br /> Mark <br /> Mark E.Nelson,P.G.,LSP <br /> Principal <br /> Horsley Witten Group <br /> 90 Route 6A <br /> Sandwich,MA 02563 <br /> (508)833-6600 <br /> (508)833-3150-fax <br /> mnelson@horsleywitten.com <br /> www.horsleywitten.com <br /> 11/16/2010 <br />
