Given the City’s proximity to Humboldt Bay, Eureka’s shoreline and landward areas will become increasingly vulnerable to sea level rise and other climate-related processes. In 2023 the City completed a Sea Level Rise Vulnerability and Capital Improvement Project Adaptation Plan. The Plan was created to support the City’s need to develop a phased climate adaptation plan, tailored to planning for coordinated implementation of projects for the City’s roads, trails, water, sewer and drainage infrastructure within the Coastal Zone.
