==Cost Summary Tables==

Total life cycle cost estimates for the three porous asphalt configurations vary substantially with the No Infiltration design being highest ($160,519.90), compared to the Partial Infiltration design ($138,144.27), and followed closely by the Full Infiltration design ($131,972.30).

Total life cycle cost estimates over the 50 year evaluation period for the three porous asphalt configurations vary substantially with the No Infiltration design being highest ($260,789.11), compared to the Partial Infiltration design ($237,742.21), and followed closely by the Full Infiltration design ($228,316.69).

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.
