Because I believe in giving equal time to all views, I have posted here the info from Spokker the ghost blogger, who thinks I am a NIMBY. He is right, I do not want this in my backyard. But unlike the usual definition of NIMBY I do not want to shove this into anyone else's backyard either. I would like to find a solution that does not disrupt anyone's backyard at all. A naive goal, I know. To that end, I had asked why this could not run down the I-5 where it would not bother anyone, and here is Spokker's answer. I do appreciate that he took the time to look it up. Thank you.
Remember to read the description of the map and remember that it's not 100% accurate due to Google Map's limitations, but I think it paints a pretty good picture overall.
Also, I have looked over the statewide EIR/EIS again and they originally studied four alignments back in the early 2000s.
B1a was the LOSSAN alternative with three tracks.
B1b was the LOSSAN alternative with four tracks.
B2 was the I-5 alternative. There were studying an aerial along the most of the length of the I-5 to Anaheim. In OC it would have followed a frontage road near I-5. A station would have been constructed near the freeway in Anaheim and Norwalk. This one was deemed to be very expensive because of the aerial structures.
B3 was the Pacific Electric right of way. This one would be ideal because it is arrow straight all the way to OC (with a station in Garden Grove). However, it travels through many more residential neighborhoods than the LOSSAN corridor. Many of these neighborhoods are poor, Hispanic communities which would have triggered environmental justice issues. Also, Los Angeles Metro owns this right of way and has plans for possibly light rail on this corridor, which would serve the local residents much better.
B4 was the Union Pacific Santa Ana Branch alignment. This had similar problems that the Pacific Electric right of way had.
As you can see, only the LOSSAN alternatives were carried forward.
All four alignment alternatives were planned to expand further down the coast and into South OC and ultimately San Diego, but unstable coastal bluffs, sensitive habitats and San Juan Capistrano nixed that idea.
Also, I discovered some information about noise. If my research is correct a train horn is 125 db, which is even louder than a high speed train at 110 MPH. In Japan bullet train noise mitigation is an artform as trains travel near residential areas at 186 MPH. Hopefully they can help us out with that issue.
