rv 2015: if you build it, will it flood? climate change vulnerabilities and strategies by james...
TRANSCRIPT
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
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?
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
• Railroad tracks
• Railroad bridges
• Signal system
• Martinez station
Assets
• Existing conditions • Physical characteristics • Functional characteristics • Governance/Management • Information availability • Consequences
Vulnerability Metrics
Assessing Vulnerability
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

• 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)
• 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)
• 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)
• 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
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.
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?
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
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.
