The town of Damsville is considering building a storm water retention dam. The dam will require the purchase of a 56-acre plot of land that is selling for $2,600 per acre on the edge of town. Site prep and construction costs for the dam are estimated to be $210,000. Annual operating and maintenance costs for the dam are estimated to be $22,000. The annual savings in flood damage reduction due to the dam is projected to be $105,000. The disbenefit to the residents living near the dam site is estimated to be $18,500 per year. When the dam is replaced in ten years the land it is built upon will be redeveloped at an estimated cost of $2,000 per acre. If Damsdville uses 3% as its cost of money, what is the B/C ratio? Should tile dam be built
