<br />different locations within the island that are conducive to construction of a trail, <br />however a meandering route that is generally parallel to the river appears to be <br />the best option. <br /> <br />The southeast end of this segment will require crossing the existing oxbow to get <br />to the Mississippi River Community Park. This crossing would be best suited for <br />the use of a culvert and building a trail subgrade over that culvert. A bridge is <br />also a possibility. <br /> <br /> <br />2. There are a number of existing traiis within the Mississippi River Community <br />Park. Utilizing the existing trail system will allow pedestrians to get from the west <br />end ofthe park to the east end, which ties in with Benton Street. <br /> <br />3. Cost Estimate and Summary of Work Items <br /> <br />Earthworks and Culvert or Bridge for Oxbow Crossing <br />Clearing and Grubbing of 12,400 Square Feet at $0.90 <br />Trail Construction 3,100 Linear Feet at $22/LF <br />Fill Embankment <br />Design/Engineering/Contingency (15%) <br />Total Estimated Costs = $73.96/LF <br /> <br />= $50,000 <br />= $ 11, 1 60 <br />= $68,200 <br />= $100,000 <br />= $34.404 <br />- $263,764 <br /> <br /> <br />4. Segment Alternatives <br /> <br />Segment 4 has one alternate possibility, which can be considered part of <br />a high water route around Kings Is/and. The high water route will be <br />important during times of flooding on the Mississippi River. Nearly all of <br />, Kings Island is within the 100 year flood zone, indicating there will be <br />times that the island would have seasonal flooding. The alternative <br />route can be temporarily signed as needed. <br /> <br />a. The high water alternate is a route along Sunfish Lake Road and <br />McKinley Street in the City of Ramsey, on easement at the <br />Ramsey/Anoka Border and on McKinley Street, Thurston Avenue <br />and Cutters Grove Avenue in the City of Anoka. A bituminous <br />trail currently exists on the west side of Sunfish Lake Boulevard <br />from the railroad tracks to McKinley Street. In the City of Anoka, <br />concrete sidewalk currently exists on McKinley Street, Thurston <br />Avenue and Cutters Grove Avenue. New trail construction would <br />be required on the easement in Anoka, adjacent to the water <br />tower and on McKinley Street in Ramsey., <br /> <br /> <br />b. Part of the primary route through Kings Island includes a crossing <br />over the existing oxbow for a connection with Mississippi River <br />Community Park. This alternate is an optional oxbow crossing <br />that can be located much closer to the main river channel. This <br />Page 14 <br /> <br />32 <br />
