  4. Calculates the cost of the control practices listed in a model run Allows you to compare the cost of different sets of practices Provides the option of applying either pre-determined costs or user-defined costs Doesn’t evaluate the cost reductions due to the use of control practices, ie, no asphalt pavement reduction determined if porous pavement is used. Cost Analysis Overview What Does the Cost Analysis Program Do?

  5. Cost Analysis Overview How are the Cost Values Normalized? A A A A A A 1 2 3 4 n Total Present Worth = Capital Cost + Land Cost + Present Worth of Annual Maintenance Cost P

  6. Cost Analysis Overview How are the Cost Values Normalized? A A A A A A 1 2 3 4 n Uniform Series Worth = Annual Value of (Capital Cost + Land Cost) + Annual Maintenance Cost P

  7. Edit and Save the Cost Template.csv File Select the Cost Data File for a Model Run Run the Program Review the Cost Output Cost Analysis Overview What is the General Cost Evaluation Process?
