A flood control project has a construction cost of $10 million in year 1; $6 million in year 2; and $2 million in year 3, when it is completed. Beginning in year 4, annual O&M costs are $200,000/year. The interest rate is 6%. Benefits also begin accruing in year 4, valued at $1.5 million that year. Thereafter, the benefits grow at a uniform rate of $30,000/year until the end of the project life of 50 years.
