Mr. Hanson <br />March 1, 2004 <br />Page Two <br />The table below outlines the options and some of the pros and cons associated with each. <br />Table 1 <br />Little Canada Watermain Options <br />Option <br />Location <br />Pros <br />Cons <br />1 <br />2nd Crossing near the middle of <br />Twin Lake Trail <br />Least expensive <br />option for supply <br />of Little Canada <br />watermain <br />Dead end length of 1400' at <br />the end of Twin Lake Trail. <br />Dead end length of 1900' at <br />the east side of Twin Lake <br />Blvd. <br />2 <br />2 'd Crossing at the end of the <br />cul -de -sac on Twin Lake Trail <br />Twin Lake Trail is <br />looped <br />Dead end length of 1900' at <br />the east side of Twin Lake <br />Blvd. <br />3 <br />2nd Crossing near the middle of <br />Twin Lake Trail and looping of <br />watermain to Twin Lake Court <br />No dead end <br />v atermain <br />Most expensive option. <br />Will require agreement with <br />Vadnais Heights. <br />City of Vadnais Heights Watermain <br />If City of Vadnais Heights watermain is utilized as the source of water for the area the length of <br />potential dead end watermain would be reduced to the 950 -feet on the west end of Twin Lake <br />Boulevard. It is very possible that this dead end could be eliminated in the future when water is <br />provided to the mobile home park north of Twin Lake Boulevard. It would be proposed to connect <br />to the existing Vadnais Heights watermain stub on Twin Lake Boulevard near Vadnais Boulevard. <br />To provide a looped system, watermain would also be extended to Centerville Road. The exact <br />alignment of the extension to Centerville Road would require additional research to identify <br />property owners willing to grant utility easements. The estimated construction costs do not include <br />any right -of- way /easement acquisition costs and it is assumed that Vadnais Heights would pay for <br />any over sizing costs above an 8 -inch main. We are working with Vadnais Heights to determine a <br />defined schedule for the installation of the Centerville Road watermain loop. We will provide this <br />information when available. Table 2 outlines the pros and cons of Option 4. <br />Table 2 <br />Vadnais Heights Watermain Option <br />Option <br />Location <br />Pros <br />Cons <br />4 <br />Connection to existing stub on <br />Twin Lake Boulevard. <br />Extension to Centerville Road <br />Least expensive <br />option overall <br />Require coordination efforts <br />to provide alignment for <br />extension to Centerville <br />Road. <br />Dead end length of 950' at <br />the west side of Twin Lake <br />Blvd. <br />C `,windows \TEMP \Itr 030104 Hanson.doc <br />- 2 9 - <br />
