Was reading an article about creation of a large public beach. It only sat 2ft above sea level and often washed over in high tide. The developers bulldozed sand from the sea side to bring it up to 12ft. But they had big troubles with wind blowing the sand inland. It almost scuttled the whole project.
So they planted hardy native grass that grew roots toward the water. It mitigated the dust problem.
Wonder if a similar thing can be done with native desert vegetation to solve this problem.
If serious about the goals, they would have followed a straight, shortest route from LA to SF, running frequently, with feeder lines to/from Central Valley and larger coastal cities (Santa Barbara, SLO, Monterey, Salinas, Santa Cruz, etc)
Given where it ended up, mainly because of Congressional shenanigans, it will end up as a little-used, publicly subsidized boondoggle. I'm all for efficient public transit, but this is such a missed opportunity, and a huge waste of taxpayer money. We'll have mid-range electric airplanes before this thing gets going.
