Tools/Resources Challenge: Our systems are designed for a static environment –
yet moving forward, stationarity will not hold true
Processes to identify important pathways of climate impacts on the built environment
Resources for understanding infrastructure sensitivities to climate-related hazards

Impacts on the Built Environment
Identify which elements in the built environment may be susceptible to what hazards potentially affected by climate change
Match time horizons
Consider non-climate drivers

Flooding of exchanges, manholes, and underground pits
Mobile line network
Higher High Tides
Soil moisture decrease the stability in structures/foundations
Large fluctuations in wet/dry spells may cause cracks in foundation
Periodic coastal flooding
Flooding of exchanges, manholes, and underground pits
Damage to infrastructure (transmission lines / towers)
Power outages
Potential loss of services
Lightening disruption
Increased Runoff / Heavy Precip. Changes in cloud

Understanding Today’s Impacts
Identify hazards of concern
Design standards Damage functions Early warning systems Impacts observed during/after past events Expert anecdotal evidence/understanding within the system Drawing from analysis conducted at similar municipalities Urban planning tools (zoning) Hazard susceptibility maps Old maps
“Quantify” the identified hazards
Local National Weather Service office – records of past events Newspaper clippings Discussions with engineers, operators, etc.

Considering Future Impacts
Using the key thresholds/relationships, consider how the exposure to these thresholds/relationships may change in the future.
Where can I easily access future climate information?

In Sum, Considering Future Impacts
Use the projections to consider how to the identified hazards/ indicators may change in the future
Also consider are the non-climate stressors that dampen or increase the vulnerability to the hazard
Consider the planning horizon / infrastructure lifetime
Actionable in light of uncertainty
