For flood control purposes, the government is considering three undeveloped sites for a water detention area. The estimated costs associated with each alternative are given below. Use the conventional B-C ratio method, with AW as the equivalent-worth measure, to determine which alternative should be selected at an interest rate of 6% per year. Assume the site will be used for 17 years before being developed for other purposes.
