A Vulnerability and Risk Assessment of SEPTA’s Regional Rail: A Transit Climate Change Adaptation Assessment Pilot

Abstract

This final report for the Federal Transit Administration (FTA) Transit Climate Change Adaptation Assessment Pilot describes the actions taken, information gathered, analyses performed, and lessons learned throughout the pilot project. This report describes the activities conducted for a vulnerability and risk assessment for the Southeastern Pennsylvania Transportation Authority (SEPTA) Regional Rail system. The project focused on SEPTA’s Manayunk/Norristown Regional Rail line and began with an analysis of recent weather-related disruptions, tying them to observed weather conditions. The results of this analysis were combined with climate model projections for the area to project future delays, annulments, and costs that may be associated with climate changes. Next, the project team and SEPTA staff held a series of conversations to discuss SEPTA’s vulnerabilities to temperature, heavy precipitation, tropical storms, and snowfall to develop adaptation strategies to address these vulnerabilities. The report concludes with recommended adaptation strategies for SEPTA and lessons learned for other transit adaptation efforts nationwide.
