<br /> <br />Feasibility Report Page 7 <br />Snelling Avenue North and County Road E - Street and Utility Improvements <br />City Project Number PW 20-0100 DRAFT <br />ICE report concluded that installation of a roundabout is considered to be justified and <br />recommended at the intersection of Snelling Avenue North and County Road E. <br />The Arden Hills City Council reviewed and discussed the above information during a work <br />session on September 21, 2020. Traffic conditions at this intersection have recently changed <br />as a result of the COVID-19 pandemic and construction along the I-35W North MnPass <br />Project. The City Council directed staff to conduct further study of the intersection as <br />described in Section 3 of this report. <br /> <br />2.4 Sanitary Sewer <br />The existing sanitary sewer within the study area consists of vitrified clay pipe (VCP), <br />polyvinyl chloride pipe (PVC), and segments with cured in place liner as summarized on the <br />following Table 1. Sanitary sewers were inspected by the City Public Works Department in <br />2019 using video televising equipment and conditions were documented as shown in the <br />right column on the table. Condition grades are based on a scale of 1 (good) to 5 (significant <br />defects). Pipe sections with condition grades between 3 and 5 should generally be <br />considered for potential rehabilitation or replacement as described in Section 3. A map <br />showing the location of the references sewer segments is provided in Appendix D. <br /> <br />Table 1: Summary of Existing Sanitary Sewer Conditions <br />Segment <br />Project <br />Area <br />Pipe <br />Material <br />Pipe <br />Diameter <br />Year <br />Installed <br />CIPP <br />Lining <br />Overall <br />Condition of <br />Main Pipe <br />MH 3-031 to 3-030 2 PVC 8-inch 1983 No 3 <br />MH 3-030 to 3-032 2 VCP 8-inch 1960 No 3 <br />MH 3-033 to 3-032 2 VCP 8-inch 1960 No 3 <br />MH 3-033 to 3-034 2 VCP 8-inch 1960 No 5 <br />MH 3-035 to 3-034 2 VCP 8-inch 1960 No 3 <br />MH 3-038 to 3-037 2 VCP 8-inch 1960 No 5 <br />MH 3-037 to 3-036 2 VCP 8-inch 1960 No 5 <br />MN 3-036 to 3-034 2 VCP 8-inch 1960 No 5 <br />MN 3-043 to 3-042 2 PVC 8-inch 1983 No 2 <br />MH 3-042 to 3-033 2 PVC 8-inch 1983 No 2 <br />MN 8-160 to 8-159 1 VCP 10-Inch 1960 Yes 2 <br />MH 8-159 to 8-158 1 VCP 10-Inch 1960 Yes 2 <br />MH 8-161 to 8-158 1 VCP 8-inch 1960 Yes 2 <br />MH 8-158 to 8-157 1 VCP/CIP 10-inch 1960 No 4 <br />MH 8-016 to 8-015 1 VCP 8-inch 1965 Yes 2
