Total life cycle cost estimates for the three permeable pavement configurations vary substantially with the No Infiltration design being highest ($187,356.33), compared to the Partial Infiltration design ($168,085.10), and followed closely by the Full Infiltration design ($162,491.78).
Total life cycle cost estimates over the 50 year evaluation period for the three permeable pavement configurations vary substantially with the No Infiltration design being highest ($262,294.27), compared to the Partial Infiltration design ($242,444.90), and followed closely by the Full Infiltration design ($234,854.66).
It is notable that a sensitivity analysis was conducted in 2019 to compare construction cost estimates generated by the tool to actual costs of implemented projects. '''The analysis found that tool estimates were typically within ±14% of actual construction costs'''<ref>Credit Vally Conservation (CVC). 2019.
