In the aftermath of Superstorm Sandy, the Federal Transit Administration (FTA) announced a competitive grant program for projects aimed at increasing the resilience of public transportation systems against future disasters. To help justify which projects were to receive funding, we developed a Hazard Mitigation Cost Effectiveness (HMCE) tool modeled on the Federal Emergency Management Agency's Benefit-Cost Analysis software that also addresses the unique elements of transit projects. At the request of end-users trained on the HMCE tool, we also began developing the Coastal Flooding Recurrence Interval Calculator to estimate the recurrence interval of flood elevation levels recorded during Superstorm Sandy. The FTA challenged us to also consider the impacts of future sea level rise (SLR) in the auxiliary tool's calculations, which we did by taking into account location, SLR trend, and the expected useful life of a facility.
