RV 2015: If You Build It, Will it Flood? Climate Change Vulnerabilities and Strategies by James Allison
Extreme weather events, flooding and rising sea levels devastate communities, destroy or severely damage costly infrastructure, and introduce a strong element of uncertainty in current and future planning. This new normal spotlights how and where we build new -- or strengthen existing -- infrastructure and communities and the governance systems that manage and regulate these decisions and investments. Hear experts tackle these issues, from Hurricane Sandy to sea level rise in the Bay Area. What are the weak links in terms of existing infrastructure, cross-jurisdictional government response systems and disaster preparedness? Learn about state guidelines and legislation. Discuss how transportation agencies deal with major transit infrastructure challenges. Discover the role of natural systems in protecting critical transit infrastructure Moderator: Allison Brooks, Executive Director, Bay Area Regional Collaborative, Oakland, California Eric Fang, AIA, AICP, LEED AP, Associate Principal, EE&K, a Perkins Eastman Company, New York, New York Projjal Dutta, AIA, LEED AP, Director, Sustainability Initiatives, Metropolitan Transportation Authority, New York, New York James Allison, Manager of Planning, Capitol Corridor Joint Powers Authority, Oakland, California JR DeLaRosa, Special Assistant for Climate Change, California Natural Resources Agency, Sacramento, California

- 1. Jim Allison Manager of Planning
- 2. The Capitol Corridor Service
- 3. Mar2nez, CA: Rail and the Larger Picture… — Twenty-‐two (22) round trip passenger trains through Martinez — Capitol Corridor (15 RTs); San Joaquin (5 RTs); Amtrak Long Distance (2 RTs) — Union Pacific Railroad freight rail operations between Port of Oakland & Roseville Yard & beyond go through Martinez
- 4. Adapta2on keeps the wheels on, but how do WE adapt?
- 5. Example Hotspot: Mar2nez Sta2on
- 6. Objec2ves — Show vulnerabilities of Capitol Corridor and freight rail physical assets to specific climate change and sea level rise scenarios. — Detailed assessment by hotspots along the route — Martinez CA hotspot to illustrate adaptation challenges in a governance setting — How can we build the foundation for smart collaborative resilience and adaptation projects?
- 8. Physical Assets • Flooded tracks and stations • Ballast damage and erosion • Damaged electrical and communication lines Service and O&M • Disruption to train service • Increased maintenance costs Impacts on Capitol Corridor
- 9. • Railroad tracks • Railroad bridges • Signal system • Martinez station Assets • Existing conditions • Physical characteristics • Functional characteristics • Governance/Management • Information availability • Consequences Vulnerability Metrics Assessing Vulnerability
- 10. Climate Change Impacts • More frequent flooding • Flooding lasts longer Storm Events • Frequent or permanent inundation • Increased shoreline erosion and wave over-‐topping of shoreline protection (e.g. levees) • Elevated groundwater levels and salinity Sea Level Rise

- 13. Considering the Risks Current water levels; 0 ft sea level rise
- 14. • 1 ft sea level rise; • 0 ft slr + 1-‐yr extreme water level (100% chance of occurring in a year)
- 15. • 2 ft sea level rise; • 1 ft slr + 1-‐yr extreme water level • 0 ft slr + 5-‐yr extreme water level (20% chance occurring each year)
- 16. • 3 ft sea level rise; • 2 ft slr + 1-‐yr extreme water level • 1 ft slr + 5-‐yr extreme water level • 0 ft slr + 25-‐yr extreme water level (4% chance occurring each year)
- 17. • 4 ft sea level rise; • 3 ft slr + 1-‐yr extreme water level • 2 ft slr + 5-‐yr extreme water level • 1 ft slr + 25-‐yr extreme water level • 0 ft slr + 100-‐yr extreme water level (1% chance occurring each year)
- 18. • 5 ft sea level rise; • 4 ft slr + 1-‐yr extreme water level • 3 ft slr + 5-‐yr extreme water level • 2 ft slr + 25-‐yr extreme water level • 1 ft slr + 100-‐yr extreme water level
- 19. Rail Poten2al Consequences — Flooding of bridges or of tracks will interrupt train operations. — Permanent or frequent inundation of ballast and roadbed will damage the integrity of the track structure. — Flooding of signal cabinets and lights can cause problems for the signal system and result in service interruptions and delays throughout the system. — Flooding of roads near the station will cause problems for passengers and other personnel trying to access the station and boarding platform.
- 20. Neighboring Property Poten2al Consequences — We don’t know them, what they do, what they want — Risks, vulnerability, and resiliency differ by asset — Do we want to team up with our neighbor? — How do we equitably pay for the adaptation? — Is one adaptation appropriate across asset types? — What about the other neighbors around that should participate in the sense of fairness?
- 21. Parks and Recreation Refineries
- 22. Long Linear Asset Exposed — Linear asset in many situations — Rail at the water’s edge — Rail in the marsh — Rail in & amongst urban area — Neighbors all around with different motivations for adaptation solutions and financial capacity — Information followed by governance structure is the largest gap
- 23. Governance Collabora2on — Consider route options with future sea level rise and flooding risks in mind. — Need to develop local and regional partnerships to approach adaptation projects collaboratively.
