The Waldorf property is a tract of land whose development value is uncertain. One acre must be preserved as wetlands: The seller claims that it is too small an amount, and the Corps of Engineers indicates that it could be large enough. The case offers students the opportunity to apply the tools of pro forma cash-flow forecasting, electronic-spreadsheet modeling, decision analysis, and discounted cash flow and to wrestle with risk aversion and develop creative alternatives for reducing the uncertainty.
