The proposed project will lessen the impacts of flooding by following the low area alignment as desired by the town, Also, the south railroad access road between the railroad and Spruce Street will remain in place, allowing utilization by the residents, These two concerns are changed by the proposed design, which were the Town's objections to the previous project, The Town prefers the proposed project, The design capacity of the proposed system is a little greater than the 1993 design, exceeding the S-year frequency. Thus, the proposed project is considered a variation (alignment) of the 1993 design in that it accomplishes the same design level. If accepted for funding, the design should proceed to optimize the work on Spruce Street and on Washington Street to reduce construction costs, and the design should look at ways to increase channel capacity without major cost increases, Also, grading of the SprucelWashington intersection, Washington south of Spruce, and Spruce east of Washington should be considered, The costs are slightly higher than the 1993 design, Two areas, Washington and Spruce, will be looked at in more detail during design to keep the costs closer to the previous estimate. In conclusion, the preliminary design of the proposed channel meets all the objectives. The Town is in favor of the alignment, the capacity is essentially the same as the 1993 design, and the costs are comparable to the previous estimate, ,,\\\11 III~""" ,....." "'\~ S.
