13-15A road is being proposed to facilitate a housing development on a scenic lake. Two alter-natives have been suggested. One of the roadway alignments is to go around the lake

and slightly impact a wetland. The second alternative will also go around the lake and will significantly impact two wetlands. The following table shows the anticipated costs for each alternative. Assuming that the annual interest rate is 7 percent, determine which alternative is preferred using equivalent annual cost analysis.
