<br /> <br />Feasibility Report Page 8 <br />Snelling Avenue North and County Road E - Street and Utility Improvements <br />City Project Number PW 20-0100 DRAFT <br /> <br />2.5 Water Main <br />The existing water distribution mains within the study area consists of cast iron pipe (CIP) <br />and ductile iron pipe (DIP) as summarized on the following Table 2. A review of the City’s <br />water main break historical records did not identify past water main pipe break or leak <br />repairs. The water main extending between Lemetti Lane and Bussard Court is considered <br />to have an elevated risk for pipe breaks due to the configuration of the water system as further <br />described in Section 3. <br /> <br />Water main was replaced and increased to a 12-inch diameter pipe along Snelling Avenue to <br />the north of County Road E in 2018, but the project did not extend the new, larger diameter <br />water main to the 12-inch diameter main along County Road E. A 150-ft segment of 6-inch <br />diameter water main was not replaced. Replacement of this 150-ft segment is an important <br />improvement to eventually provide higher water supply conveyance capacity to the northern <br />portion of the city. <br /> <br /> <br /> <br />2.6 Drainage <br />Snelling Avenue North between Highway 51 and Arden Place is a rural section roadway with <br />minimal storm sewer. The majority of runoff is directed to ditches along the roadway, which <br />ultimately drain to ponds and wetlands within the Johanna subwatershed area. <br /> <br />Table 2: Summary of Existing Water Main <br />Street From To <br />Project <br />Area <br />Pipe <br />Material <br />Pipe <br />Diameter <br />Year <br />Installed <br />County Rd E 260' East of Snelling Ridgewood 2 12-inch DIP 1968 <br />Snelling County Road E 150' North of CR E 2 6-inch DIP 1982 <br />Snelling Arden Place 470' N of Arden Pl 1 6-inch CIP 1969 <br />Snelling Arden PL Crossing Arden PL Crossing 1 8-inch CIP 1969 <br />Snelling Skiles Ln Lametti Ln 1 8-inch CIP 1969 <br />Snelling Glenarden Crossing Glenarden <br />Crossing 1 8-inch CIP 1969 <br />Snelling Lametti Ln Bussard Ct 1 8-inch CIP 1969 <br />Snelling Cummings Crossing Cummings <br />Crossing 1 8-inch CIP 1969 <br />Snelling Bussard Ct Bridge Crossing 1 8-inch CIP 1969 <br />Snelling Bridge Crossing Bridge Crossing 1 8-inch DIP 2018 <br />Snelling Bridge Crossing South Termini 1 8-inch CIP 1969
