Well, some bridge maintenance would be nice. Additional work to strengthen highway passes, communication infrastructure, government owned buildings...maybe some seismic engineering or reinforcement done on the unreinforced masonry elementary schools, some of which (in Seattle) were last touched in the 1990s. On an individual level, homes built before 1980 should be updated to meet modern earthquake foundation codes.
All of these problems are known, but not funded, because who cares? Disaster management nerds?
