The City Council then focused on the cost of constructing a wall through the LaPort Neighborhood (Segment C). This was estimated to be $400,000 after adding in engineering and other costs. Based on this amount, the City Council questioned what impacts this expenditure would have on the City finances. On July 6, 2004, Staff presented two options for Segment A. The option of extending the wall and not impacting the pond (Option 1), and the option of extending a berm and impacting the pond (Option 2). The estimated cost of Option 1 was $277,189.43 and the estimated cost of Option 2 was $267,800.60. Neither option accounted for Staff time and costs. Since the proposal for Segment “A” would be to have Staff administer and inspect the project, this cost should be factored in. The Public Works Director will need to dedicate numerous hours to perform project administration. The Public Works Supervisor will act as the on-site project foreman - again, requiring the dedication of numerous hours. It was conservatively estimated that Segment “A” will require $20,000 to $25,000 in Staff time. Given the following: 1. ) The costs of any option involving a berm in Segment “A” and a project managed by the City will be equal to the amount offered to the City by Mn/DOT. 2.) A wall will require the removal of only a couple of trees, whereas the berm option would remove over seventy (70) trees. 3.) The City will be taking on all liability for the construction and performance of a berm, whereas Mn/DOT will take on all responsibility and liability for a wall. Staff continued to recommend that the City require Mn/DOT to construct a noise wall through segment “A”. On July 6, 2004 Staff presented new cost estimates that included engineering and other factors. These cost estimates were: For segment "A", estimated total cost (excluding Staff costs) is $277,189.43 for a wall / berm combination or $267,800.60 for a berm only. Including Staff time both options would be equal to or exceed $300,000. For segment "B", estimated total cost $127,669.50. For segment "C", estimated total cost $426,710.70. Finally, on July 6, 2004, Staff provided a cost comparison to a residential street project. The comparison concluded that assuming Municipal State Aid Funds and bonding are used as funding sources. The City Council would have two choices:
