Heavy overflowing has occurred in Karaikal, a small city in the South of India, as it is located along the river although MGR Reservoir and SIVAJI Reservoir are operating nearby. This has pushed the people living in valley areas near the river to subscribe to flood-related insurance. The insurance costs between INR200 and INR3000per year. To lessen the likelihood of overflowing, the government commenced a project valued atINR300million to raise the earthwork along flood-prone portions of the river. As a result, 12,345properties were freed of the federal mandate to purchase flood insurance. In addition, historical records indicate that damage to infrastructure will be avoided, which amounts to an average benefit ofINR17,300,000 on yearly basis. If the average cost of flood insurance is IR350per household per year, calculate the benefit-to-cost ratio of the levee-raising project. Use an interest rate of 5% per year and a 30-year study period.
