California’s transportation infrastructure faces growing challenges from extreme weather, including heavy rainfall, flooding, landslides, wildfire and erosion. Recent state investments highlight the increasing importance of preparing existing infrastructure for these risks.
In May, the California Transportation Commission allocated nearly $70 million for weather-related highway repairs, including projects addressing storm damage, slope stabilization and other improvements intended to strengthen the transportation system against severe weather and natural disasters.
The state has also invested in longer-term planning. Caltrans announced $23.6 million in Sustainable Transportation Planning Grants for 58 local projects, with funding supporting efforts that include climate adaptation, disaster preparedness and more resilient transportation systems.
These investments reflect an important shift in infrastructure management. Maintaining an asset is no longer simply a matter of responding to deterioration as it occurs. Agencies increasingly need to understand how changing environmental conditions may affect bridges, roadways, drainage systems, slopes and other infrastructure throughout their service lives.
Asset management can play an important role in that process. By combining condition information with inspection history, environmental exposure, risk and anticipated maintenance needs, agencies can better identify vulnerable assets and prioritize limited resources.
As California prepares its infrastructure for future conditions, resilience is becoming an increasingly important part of long-term asset management—helping agencies not only maintain infrastructure, but anticipate risks before they become more costly problems.
