After decades of channelization and bank stabilization, the Corps of Engineers is considering a major wetland restoration project along the Embarrass River that would have two primary benefits: flood control and fish restoration. The primary costs would be engineering/design costs and construction costs. Because wetland restoration is a complex project involving removing fill, reestablishing proper hydrology, reintroducing native flora and fauna, and controlling exotic species, there is considerable uncertainly in project benefits and costs. a. Based on the data table provided, calculate the expected benefit-cost ratio for the wetland restoration project. Show your work.

In terms of the Embarrass River wetland restoration project, what other impacts (benefits or costs) might be included in the environmental impact assessment the Corps of Engineers would be required to undertake in compliance with the National Environmental Policy Act? Provide two benefits or costs that the Corps of Engineers would also want to include in their assessment
