[Your estimate should be considered a maximum. As the neck narrows, an increase in discharge may allow the river to rapidly cut across the narrowing neck. Thus, the frequency of major flooding and the rates of erosion are linked together.]
An interim report by the U.S. Corps of Engineers suggests that flood-control levees might be feasible for at least some of the houses.
Given projected costs, the Corps requires that the levee be designed to last for 50 years. As a concerned tax payer, you are asked to vote on a tax increase to raise funding to construct the levees. Based on your knowledge, how would you vote on the construction of Levee B?
As a concerned property owner and tax payer, you must be involved in such decisions! Return
