In a recent article in the American Society of Civil Engineers (ASCE) Civil Engineering Magazine and Civil Engineering Source “Key Northern California Highway to Be Protected from Sea Level Rise,” author Jay Landers highlights how the State of California plans to protect a critical coastal highway from climate change and sea-level rise. Landers explains that California State Route 37 (SR 37) links east-west transportation in the North Bay Region, a subregion of the San Francisco Bay Area. As a result, the California Department of Transportation or Caltrans and local partners are assessing adaptation actions for safeguarding SR 37 from high water across both short-term and long-term time horizons. Early estimates of the cost of future-proofing range from hundreds of millions of dollars in the short-term to billions in the long-term. Given its low elevation and close proximity to tidal waterways, the key highway is subject to flooding — with higher probability when strong storm events coincide with high tide conditions. During past flood events, Caltrans implemented numerous emergency measures: deploying flood walls, raising pavement levels, improving adjacent drainage, and restoring nearby levees.
