Much like in the Del Mar segment, there's a great deal of "show me the money" here. The Del Mar segment is farther along in developing the money, but it still isn't there to do the job. The process hasn't really even started (other than some very preliminary studies) in San Clemente.

In the short term, "emergency" funding can usually be found to clean up a landslide and even fix that trail bridge. In the longer term (think 100 year or more lifespans for major public facilities like the railroad), big investments need to be made to move things that are politically fraught in the US.

For some perspective regarding sea level rise, which is a long-term factor (100 years), this might be interesting: [www.climate.gov]. Essentially, it's happening, but some of the more extreme scenarios are less likely than previous work suggested. Of course, it's a big-picture thing; there are studies going on to get more granular. And sea level is of course relative; water is being added to the oceans and thermal expansion is happening, but the land also moves, so the numbers will be different everywhere. Depending on the geology and what's happening with ground water, California coastlines are moving both up and down. In the long term, though, the SL direction is up.

Our ancestors dealt with this at the end of the last big ice age. Of course, at the time, they didn't have big cities and railroads...
