Note this is just conceptual alignments and requires regional electrification. Key new things: -SMART to Salesforce via Golden Gate Bridge -SMART on Richmond/San Rafael Bridge to East Bay -Carniquez to Vallejo tunnel for CC -New North Bay Service LMK if you need more clarification!

An extension of SMART to the GGB would require a truly galactic realignment in Marin County politics. Electrification, fixing of the SMART-ferry gap, fast ferries out of redeveloped San Quentin - all of those things I can imagine before a southern extension.

Southern Marin is basically impossible to do TOD as the terrain makes for teensy walkshed windows. I might be willing to send BART from Richmond to San Rafael SMART Station even though I get Marin's primary destination is SF -- not the East Bay. Otherwise, I like the buses and ferries for Marin.

Agreed (tech/agency ambivalent obviously) bsky.app/profile/warr...

All this to say, I think of Richmond as a better terminus/tie-in location for SMART than southern Marin. There are just way too few people south of Blithedale Ridge in Mill Valley to justify the kind of rail investments that they will oppose anyway.

Definitely. That's why I would prioritize the Richmond bridge & a Vallejo tunnel. Imagine hopping on a train at Salesforce, Link21 to Oakland, then either the Richmond or Vallejo alignment to get to Sonoma, Napa, Santa Rosa, in addition to ferry service to those lines via Vallejo or Larkspur ferry

we live in a world where Golden Gate Bridge traffic peaked in 1988, the commute is not relevant to Marin like it used to be. And it's not like Southern Marin wants a metro the only way SMART gets from Larkspur to SF is if technology gets invented to tunnel insanely cheap all the way under the Bay

Yeah, Southern Marin and its mountainous terrain with little walkability isn't exactly made for TOD. The best you're ever going to do in Southern Marin is local buses and ferries.

Sean Maiwald

Completely agreed lol this is a pie in the sky take as that would likely be the last big rail gap in the Bay Area as all of the other elements would be completed first, even Dumbarton

Yeah, not trying to crap on it or anything. Like you suggest, it's probably the lowest priority and also the most politically challenging inter-bay gap to fill.

This is all 30-50 years out stuff, but I would love to see coordinated thinking about a new RSR Bridge with rail connecting to a redeveloped SQ, with a SMART station and ferry landing (which would be 10 minutes faster to SF due the ability to avoid the channel).

That said, how you get regional rail *to* the eastern landing of the RSR is beyond me.

Probably the best option, but skipping San Quentin for the TOD potential and new ferry stop may not be tenable unless you figure out a short funicular/gondola type of connection down to the water

Sorry, I meant from mainline or BART to the *eastern* landing of the RSR Bridge past (under?) Pt Richmond.

I suspect it would be a long and high viaduct to/from Ohio Ave. Difficult but not impossible

Ответ для Sean Maiwald
Warren Wells, AICP

Yeah, you'd need quite the span over the BNSF yard there, and even then I'm not sure what happens without going through the Chevron property.

How you get from a bridge into either corridor depends a lot on the service you intend to run, and what is already existing or planned at the time. One example: do you want direct San Rafael to Sacramento service?

Ответ для Warren Wells, AICP
Sean Maiwald

Absolutely. The San Quentin redevelopment could finance a large chunk of this if an EIFD or similar mechanism is established. The old ferry parking lot and dock could be similarly redeveloped, too, for revenue.

While we're self-promoting and planning ahead, here is one of many permutations I have for railstituting some of the most popular Muni bus routes: www.google.com/maps/d/u/0/e...

Yeah I think it's last but I still think it's inevitable eventually, so when we're designing alignments that will still exist in a century, we should try to avoid shooting ourselves completely in the foot with the choices we make today!
