A potential site for a reservoir is being evaluated for two mutually exclusive options: a small water supply reservoir or a large flood control reservoir. Cost and benefit data on the two options are provided below. Interest rate to be used is 10%. Each alternative has an initial cost, an annual operating cost, and an annual benefit. Each alternative also has a mid-life maintenance cost that occurs 20 years after the start of the project.
