Source: Eastside Transit Corridor Phase 2 Alternatives Analysis, Addendum. It just rolls off the tongue and into your heart :)
LAist reports that Metro has whittled down its options for a new southern extension of the Gold Line light rail train. Metro released a document called an Alternatives Analysis which details their reasoning.
The good news is that both of these are proposed as over 90% aerial (as opposed to at grade), although it's important to insist that this be done with sound walls everywhere to protect the neighbors from noise. I would even argue for putting them in where they don't seem necessary now, because land use is not static over time. Today's strip mall could be tomorrow's walk-up apartment building or rowhouse block.
See the following table for a comparison of line characteristics:
Do this with sound walls Metro, and you'll have tons of my respect. Be cheap on sound walls, and generations of families will curse your name. Doesn't sound like that hard of a decision. Don't be cheap!
