5 1 - Climate Hazards in the Bay Area Sea Level Rise Downpour Current in/hr 100-yr 1-hr storm intensity Future modest, recommend 30% greater intensity Flooding Current 100- and 500-year FEMA floodplain Future recommend add ½ mile extent to floodplain

6 3 Adaptation Strategies Best Practice: A Review of Global Rail Sector Climate Adaptation Strategies Adaptation Strategies For each of the 4 study areas By discipline: Planning, Design/Construction, Operations, Maintenance Type of hazard adapted for (SLR, flooding, and/or downpours) Prioritizing Adaptation Strategies Timeframe & cost Cost-benefit score For each of the 4 study areas

16 Asset Management Enterprise Level Asset Management Component Asset Management Policy and Strategy Risk-Based Asset Management Approach Opportunities to Integrate Climate Adaptation Consider climate change in asset management goals, policies, and/or plans. Map areas vulnerable to projected climate risks. Inventory critical assets, create risk profiles, and develop risk mitigation strategies. BART Status / Notes Climate change considerations to be added to asset registry Environmental/Climat e change and Asset Management Team Coordination SLR maps completed for ART East Bay area Prioritized list of SOGR assets identified Asset Management Activities Develop adaptation strategies at enterprise, asset-class and lifecycle asset management planning levels AMPs for 5 asset classes are underway Financial Requirements Incorporate climate risk mitigation strategies into shortand long- range plans, capital and/or O&M budgeting processes. Continuous Improvement Monitor asset condition in conjunction with climate change indicators to determine if/how climate change affects performance.

17 Asset Management Asset Level Life Cycle Management Component Opportunities to Integrate Climate Change Adaptation Roles and Responsibilities Identify resource (person, organization, or program) for climate risk data and how it will be maintained. Asset Inventory Overlay or relate inventory to climate-related data. Condition Assessment & Performance Monitoring Document condition and performance monitoring in conjunction with climate conditions to understand how an asset performs under various climate extremes and if a climate risk mitigation strategy that has been implemented is effective and responsive. Preventive/ Reactive Maintenance Plan Update preventive and reactive/corrective maintenance practices to address different operating conditions Asset Policy and Strategy Include goals for level of service requirements and climate change-related outcomes. Asset Lifecycle Management Consider climate risks to asset throughout each phase: (1) Design/procure (2) Use/operate (3) Maintain/monitor (4) Rehabilitate (5) Dispose/reconstruct/replace Capital Programming and O&M Budgeting Consider costs of climate-related strategies (incl. costs to replace vs. retrofit vs. abandon) and the value or benefit of the measure to facilitate prioritization. Performance Modeling Conduct performance modeling in conjunction with climate conditions. Continuous Improvement Update asset lifecycle management plans as conditions and performance change.

20 Water Intrusion Incident 11/30/12 Incident: A20, Heavy rain and drain pipe blockage caused rooftop ponding+intrusion and flooding from interior floor drain. Speed code issues occurred. (~3 hrs in late afternoon) Repair Damage: PLM card and power supply for VPI (~$4,800) Pipe replacement (~$500) Labor (~$25,000) Delay Impact: 34 Secondary delays between 5 and 11 minutes Up to 21,000 riders impacted
