\. <br />IV. Cost Analysis <br />Detailed cost estimates for the proposed improvements are presented in the appendices. These costs <br />include a 5 percent contingency, a 15 percent allowance for design, inspection, legal, and <br />administration costs, and a 5 percent allowance for capitalized interest and bonding costs during <br />construction. The costs arc based on 1996 constraction. The ENR index for October, 1996 is 5672. <br />A summary of the estimated costs for the proposed improvements is presented in Table 2. <br />Table 2. Summary <br />Item Estimated Cost <br />North Long Lake <br />Sanitary Sewer Laterals $296,746 <br />Trunk Facilities $176,304 <br />Dakota Avenue Street Surfacing $19,284 <br />Long Lake Country Club <br />Sanitary Sewer Laterals $319,368 <br />Trunk Facilities $237,853 <br />Total Project $1,049,555 <br />The cost estimates do not include easement costs that could be incurred on the project. <br />It is recommended that the trunk costs be assessed uniformly over the area to be served. This results <br />in a trunk charge of $7,530.00 for each of the 55 units being served. The lateral costs would be <br />$11,848.00 for each of the 52 units being served if the two areas are combined. Dakota Avenue <br />street surfacing has not been calculated into either the trunk cost assessment or lateral assessment <br />charge. <br />Sanitary Sewer Improvements
