3.1.7. The Beginning of the Century
The 2001 Tarzana earthquake was without a doubt one of the greatest calamities to befall Los Angeles in recent times. With a magnitude figure of 6.9 Mw and an epicenter on the southern edge of the San Fernando Valley, the earthquake affected both the Valley and the Los Angeles Basin heavily – particularly along the faultlines that run through the metropolitan area from northwest to southeast. The main quake was followed by an estimate of over a thousand aftershocks, of which two reached above 6 Mw, and the resulting chaos is likely to have worsened the damage. Buildings were flattened, roads damaged severely, and thousands were severely injured. Ground acceleration was the fastest ever measured in a US urban area, and shakes were felt as far away as Las Vegas [1].
Structural damage from the quake was felt throughout the Los Angeles metro area, but particularly in the Valley and on the Westside – areas that, in a morbid twist of fortune for the LATC, were also relatively sparsely served by the subway system due to lingering anti-transit sentiment among the mostly affluent residents. Most of the high-capacity transit in the area took the form of blue express buses (the Blue Arrow name was still two years away), and while the fleet was damaged by the earthquake just as private vehicles were, the restoration of service was relatively quick. The only line that was severely damaged was the Blue Line, whose northern branches all ran close to the severely impacted areas. As a result, Blue Line service had to be cut back to Echo Park while restoration works took place, lasting most of the winter. The Hollywood branch (onto which the brunt of the effort was placed, partly due to its more damage-prone alignment and partly due to its symbolic importance for the city) was restored fully by December, while the Van Nuys and San Fernando branches took until March of 2002 before they could open.
However, the earthquake was to have a major effect on transit
planning. The LATC had made plans to finally extend the Green Line all the way to Santa Monica, and the Blue Line to Beverly Center to connect with it, but these had to be shelved after a renewed seismological study revealed station alignments to be vulnerable to earthquake damage. In addition, although the residents of Santa Monica and Culver City were gradually becoming more pro-transit (in line with the general shift toward liberalism seen by the upper middle class in the 00s), Beverly Hills remained as intransigent as ever toward the LATC, having to be dragged kicking and screaming into even the common-sense-based and largely beneficial Transit 2000 program. They simply refused to allow any subway service within their city limits, and any attempt at an alignment bypassing Beverly Hills would result in a virtually useless line.
So it was that an alternative was sought, and in mid-2003, it was found. A proposal was made for a bus service that would run articulated buses along a dedicated lane along Santa Monica, La Cienega, Beverly and (again) Santa Monica Boulevards from the Blue Line terminus in West Hollywood via the Yellow Line terminus at Beverly Center to the Santa Monica bus terminal. Beverly Hills authorities let it be known that this would be an acceptable agreement to them, likely as no direct connection would come into existence between them and the Eastside, and on New Year's Day 2004, the new line was inaugurated. The buses were painted in a blue livery and branded as the “Blue Arrows”, a name that came to be used for all LATC express services within a short time.
Rapid transit planning, meanwhile, was focused toward the construction of the La Brea-Crenshaw Crosstown Line, a scheme that was designed to facilitate the westward shift of LA's job market by providing a straight connection between the Valley, Hollywood and LAX. A second crosstown line along Vermont Avenue, with its north end at Glendale and its south end on the USC campus, was also studied, but was found less feasible than the La Brea-Crenshaw alignment. Planning was slightly faster in this case, as nearly the entire line would be in Los Angeles itself (all but the Inglewood section, which was already in existence although as part of the Blue Line), but the line still required appropriations significant enough that a public vote was necessary.
The measure was put on the ballot alongside the mayoral primary in March of 2005, and the construction of the line quickly became a major issue in the mayoral race as a result. Mayor Yaroslavsky campaigned in support of it, arguing that it would bring jobs to LA, take pressure off downtown and benefit tourism by more closely matching visitors' travel patterns. His major opponent, Republican councilman Hal Bernson [2], opposed it as a waste of public money, citing the need to maintain existing lines and the ability to use express buses to cover crosstown routes at a fraction of the cost. Both men were veterans to the field of transit, Bernson having served as chair of the city council's Transportation Committee, and both had their followings, but Yaroslavsky remained a fairly popular mayor, and while he failed to win outright at the primary stage, the fact that the measure passed by a narrow margin was seen as a good sign for his chances of reelection to a fourth term. Indeed, after a fairly eventless general campaign, Yaroslavsky ended up defeating Bernson by a 52-to-48 margin, which must be considered an impressive feat given that it was his third election as the incumbent.
The appropriate planning actions having been taken and clearances given, construction commenced in August of 2006, using a tunnel boring machine for the first time in LA history – this was considered the preferable option as the alignment of the new line didn't follow the street grid as closely as previous lines had [3]. Construction was refreshingly eventless, and the line opened to great fanfare on March 21st, 2009, with speeches given by Governor Solis and Mayor Ridley-Thomas to mark the occasion, and the line was christened the Purple Line after a public consultation on the matter. LA had yet another service added to its rapid transit system, and the line achieved its goals of drawing in new riders and taking pressure off the Blue Line.
Since the Purple Line, no major transit expansion efforts have been made. The LATC subway system of today has six services on three line corridors, with 129 stations and over 220 km of track [4], in addition to almost as large of a network on the Pacific Electric side of things. A new series of cars, the 6000 series, was commissioned from Rohr to serve the Purple Line, and along with the 90s stock it makes up the overwhelming majority of rolling stock in the system. Since the refurbishments of the 1990s, while regular maintenance has taken place, no major work has been done to modernize the older lines, and some stations are once again beginning to show their age, but it's a far cry from the decrepit state of the system in 1993. The 2012 American Community Survey, which recorded modal splits in major American cities, showed that an estimated 24% of Angelenos use transit to commute, with around 67% driving and insignificant numbers walking or cycling [5].
[1] This is broadly similar to the OTL Northridge earthquake, except insofar as it takes place seven years later, is slightly stronger due to built up tension over this period (this is where it becomes glaringly obvious that I know next to nothing about seismology, so apologies if this suspends the disbelief of any seismology fan who might be reading) and the epicenter is slightly closer to the southern edge of the Valley than OTL.
[2] ITTL, due to the more public-works-friendly and slightly less liberal bent of the Democratic Party, LA remains somewhat competitive between the two major parties. Expect any sort of Greens or similar to be strong here as well though.
[3] The line runs alongside the Blue Line from LAX to Windsor Hills, then along Crenshaw Boulevard up until about I-10, where it continues due north to meet the Yellow Line at Vineyard Junction (the meeting of Pico, Venice and San Vicente Boulevards). From there it turns northwest slightly, joining up with La Brea Avenue at Wilshire, and continues to follow La Brea and later Cahuenga Boulevard until meeting up with the Blue Line again at Garnsey, from where it takes over the San Fernando branch.
[4] Yes, TTL's United States uses metric – no President Reagan or similar intransigent conservative in office from 1981 means the gradual conversion that was started under the Carter administration (see Interstate 19 and Fenway Park's distance markers pre-2002) is carried to term. And as for the network size listed, it's technically an inflated figure as it counts the sections of line shared by the Blue and Purple lines separately for the two lines, but something around 200 km is probably an accurate length estimate. Placed in OTL this would make the LA Subway the second-largest transit system by track mileage in the US, with only New York's being larger (though the Chicago “L” also has more stations).
[5] This may sound disheartening after all this work building a transit system, but it's similar to what we see IOTL in places with relatively substantial transit like Boston or Chicago. For comparison, Los Angeles' OTL figure is 11% transit commuters.
