Why are natural hazards such as earthquakes, sea level rise and flooding not integrated more directly into the plan?

Plan Bay Area is a long-term, regional-scale plan covering 101 cities and nine counties, over 150 major transportation projects, and many other transportation and land use projects over the next approximately 27 years.  The Plan and the Environmental Impact Report address natural hazards at the level appropriate for long-term, programmatic regional plans.  Potentially significant site-specific natural hazards caused by projects implemented under Plan Bay Area will be addressed at the project-specific level.  MTC and ABAG will continue to monitor these issues and revise Plan Bay Area in response to the changing environment every four years, as required by law.
