The North Corridor: Centralized Transit in the Southeastern San Fernando Valley

For LA to have a successful transit network, that network needs to be centralized around an urban core. This means land closer to the core is more valuable for achieving centralization than land farther out.

In general, the San Fernando Valley lives up to the myths about Southern Californian sprawl and decentralization. It's made up of a constellation of small towns set in a suburban sea with no dominant urban focal point. Its most centralized city, Glendale, lies too far east and is too geographically contained to exert any significant centralizing pull on the rest of the Valley. Meanwhile, nestled at the western foot of the Verdugo mountains, Burbank has an elegant pattern of radial streets that nonetheless fail to exert any significant pull upon its surroundings. To the southwest, the northern opening to the Cahuenga Pass acts as a funnel for traffic headed into and out of Central Los Angeles. But right at the mouth of the pass, like a boulder in a stream, sits the monolithic Universal City obstructing centralization at an otherwise ideal site.

Downtown LA exerts the ultimate pull, however weak, upon the Southeastern San Fernando Valley. That pull is logically strongest at the neck of the Valley just west of Glendale and at the mouth of the Cahuenga Pass, but it is negated by the dissipating cityscape to the north and west. What little centralization that exists in the San Fernando Valley is concentrated in the southeastern area, and that is where transit infrastructure needs to be developed.

EXTENSION OVERVIEW




The Orange Line BRT stretches west from Lankershim Boulevard to Warner Center, reaching deep into areas of the San Fernando Valley that are farthest from downtown LA or even the more urbanized parts of the Valley itself. As a result, the Orange Line serves mainly as a commuter line for residents of LA's low-density outskirts. As such, it enables sprawling, low-density development rather than facilitating compact, centralized, high-density land usage.

Rather than spreading our transit resources thin to subsidize sprawl, we should instead be using transit to promote centralized development and strengthen the urban core. In the San Fernando Valley, this means focusing transit investment in its southeastern corner.



The Orange line should be extended from its current eastern terminus at North Hollywood, through Burbank's Media District and along the foot of Griffith Park, to downtown Glendale. Between Van Nuys and Glendale, the Orange Line should be converted to light-rail. West of Van Nuys it should remain as Bus Rapid Transit for now since this is a peripheral route and since rail service beyond Van Nuys would dilute service to the southeastern "core" and encourage further decentralized development.

SEGMENTS AND STATIONS


View Larger Map

North Hollywood/Media District Tunnel

From its present terminus at North Hollywood, the Orange line would enter a tunnel and head south underneath Lankershim Boulevard, east underneath Riverside Avenue and Alameda Boulevard, and south underneath Buena Vista. The Tunnel would be approximately 4 miles long, include 5 stations (Lankershim/Riverside, Riverside/Cahuenga, Alameda/Hollywood Way, Alameda/Olive, and Alameda/Buena Vista), and emerge on the south side of the Ventura Freeway. Lankershim/Riverside would also be the site of a new Red Line Station.

South of Los Angeles River (SOLAR) segment.

From the portal on the south side of the Ventura Freeway, the Orange line would cross the LA river and run at grade along the southern edges of the river and the freeway, roughly parallel to Zoo Drive. This segment would be approximately 3 miles long, include a station at the Los Angeles Zoo, and cross the LA River into Glendale at Doran Street.

Ventura Freeway/Downtown Glendale segment

Between the LA River and Central Avenue in Glendale, the Orange Line would run at grade down the center of the Ventura Freeway, which may need to be widened in places to accommodate a rail bed. At Central Avenue, it would go underground and head south below the freeway (similar to the way the Gold Line submerges below the freeway just north of Memorial Park station in Pasadena). It would reemerge onto Orange Street and run at street level from Doran to Broadway (its new eastern terminus). Orange Street would be devoted exclusively to Orange Line Light Rail traffic. This segment would be approximately 2 miles long and include 3 stations (Ventura Freeway/Pacific, Milford/Orange, and Broadway/Orange).

DEVELOPMENT

Burbank Media District


Improved transit access from the east, west, and south would enable more intensive development of the Media District, allowing it to develop similarly to close-in suburbs of Washington, DC, like Bethesda and Silver Spring, MD.

Lankershim Corridor

The Orange Line, with its new stations on Riverside Drive at Lankershim and Cahuenga, would link Universal City, North Hollywood, and West Toluca Lake as a continuous urban corridor similar to the Rosslyn-Balston Corridor in Northern Virginia. All four stations of the Lankershim Corridor would have direct transit connections to the Burbank Media District, Downtown Glendale, and Van Nuys, while three stations would have direct connections to Hollywood and Downtown LA. Furthermore, the Lankershim Corridor would become (via the Red Line) the primary connection for traffic between the Valley and Central Los Angeles.

Downtown Glendale

In addition to unlocking valuable downtown land for more intensive use, the Orange Line would establish a stronger connection between Glendale and the rest of the San Fernando Valley, thereby expanding Glendale's transit hinterland. In particular, the improved connection between the Glendale's business district and the Burbank Media District (as well as Universal Studios) would amplify their collective regional competitiveness. This northern business corridor, eventually extending to Pasadena, could potentially become a northern counterpart to the Westside.

Fremont Park, Glendale

The Ventura Freeway/Pacific Ave. station would allow the intensive development of Glendale's Fremont Park neighborhood. This neighborhood has numerous assets that make it ripe for more high intensity development. It is already an area of multi-family housing, is half a mile from downtown Glendale, and is served by a park which could serve as a community focal point. The Orange Line station would add extensive rapid transit connections to this list of assets, unlocking this neighborhood's currently suppressed potential.

Los Angeles Zoo/Griffith Park

The Orange Line would also improve access to the Los Angeles Zoo and to Griffith Park.

FURTHER AFIELD

Centralization in the southeastern San Fernando Valley would bring people within closer reach of other destinations not served directly by the Orange Line, such as:

Downtown Burbank
Burbank Airport
Studio City/Valley Village
Van Nuys/Sherman Oaks
Hollywood

The Sepulveda Line

The Westwood Bus Tunnel coupled with increased centralization of El Segundo's central business district would lay the groundwork for a trans-Sepulveda bus line connecting the Westside, the South Bay, and the San Fernando Valley. This bus line would utilize existing freeway infrastructure to provide regional service while tying into local transit networks and connecting the Orange, Green, and future Purple (Wilshire) lines.



The first segment of this route would begin at the El Segundo Green Line Station and run north on Sepulveda Boulevard to the Howard Hughes Center, with stops at Mariposa, the LAX Bus Center, and Westchester (Manchester Ave) in between.

The second segment would run along a bus/carpool lane on the 405 between Howard Hughes and the 10. It would then take the eastbound 10 to the Overland Avenue exit. There would be no stops along this segment since this area is already served by local surface routes.

The third segment would run north on Overland, enter the Westwood Bus Tunnel, and exit the tunnel at Wilshire Boulevard to rejoin the 405. This segment would serve four of the five tunnel stations.

The fourth segment would run along a bus/carpool lane on the 405 from Wilshire Boulevard through the Sepulveda Pass to Ventura Boulevard in Sherman Oaks with no stops along the way.

The fifth segment would run along Ventura Boulevard to Van Nuys, then north to the Van Nuys Orange Line station.

Centralized Transit in the South Bay

Back in April, I composed a series of posts about centralization around Westwood, Hollywood, and Downtown, using Steve Belmont's assertions in his book Cities in Full as my guide. He articulates the model of a compact, high density commercial hub tightly ringed by what Belmont refers to as the "Central Residential Ring": close in neighborhoods ideally suited for high density housing because of their proximity to the centralized employment and transit resources.

The South Bay subregion is ideally suited for increased centralization. The area roughly bounded by Slauson to the north, Vermont to the east, Artesia to the south, and Santa Monica Bay to the west already has relatively high population density, an underutilized commercial core (El Segundo's Central Business District), and a transit network loosely centered on that commercial core.


View Larger Map

The area comprising the Central Residential Ring includes the cities of El Segundo, Inglewood, Hawthorne, Gardena, Lawndale, and Manhattan Beach. It also includes the Westchester area of the city of Los Angeles and the northern section of Redondo Beach as well as the unincorporated areas of Westmont, West Athens, Lennox, Del Aire, an Alondra Park.

The entire area covers a total of just under 57 square miles, within which live approximately 511,000 people at an average population density of 8,879/sq. mi. When the massive area occupied by low or unpopulated areas like the Chevron Oil Refinery and the census tract that includes LAX are excluded, the population density rises to 10,564/sq. mi. For comparison, Washington, DC, has a population of 588,292 and a population density of 9,581.3/sq. mi.



Despite a decent sized population and high average residential densities, the South Bay core remains a disjointed urban landscape. This is due to its extremely car oriented design, key gaps in the public transportation network, and a fragmented residential organization. However, all the elements are in place to easily encourage development of greater centralization in this subregion.

Employment is already centralized in the area bounded by Sepulveda and Aviation Boulevards, Rosecrans Avenue, and Imperial Highway, but the land remains extremely underutilized. Valuable land is given over to parking lots which separate the office buildings they serve from the streets and sidewalks. The area is unpleasant to walk in because it is so dominated by automotive traffic.

Transit connects the downtown core directly to Santa Monica, Westwood, Downtown, Long Beach, and San Pedro. A small constellation of satellite transit hubs (LAX City Bus Center, Downtown Inglewood, Howard Hughes Center, and South Bay Galleria) compliment that core and provide additional connections beyond it. However, the lack of connectivity within the core discourages El Segundo from fulfilling its role as the primary transfer point for all South Bay traffic. This is similar to the situation surrounding the Downtown Connector: the most vital links lie at the core and their absence greatly weakens the entire network.



The area is rich in residential environments, from Manhattan Beach and Hawthorne to Westchester and Inglewood, but they too are disconnected from one another due to reliance upon automobiles and the lack of a cohesive, concentrated downtown core. Just like the satellite transit hub network, housing and commercial development in nearby Inglewood, Hawthorne, and Gardena would also benefit from a strengthened core.

In terms of the public transportation network, these are the proposals I offer for improving connectivity in El Segundo's Central Business District:


  • Designate the El Segundo Green Line station as main transfer point for buses in El Segundo's downtown core.
  • Extend Metro 439, Metro 120, BBB 3, and CC 6 buses from their current termini at Aviation to the El Segundo Station (439, 3, and 6 via Aviation Blvd; 120 via Nash & Douglas.
  • Extend Metro 715 from its current stop at the LAX Bus Center to the El Segundo Green Line station via Aviation Blvd.
  • Create direct shuttle service between the El Segundo Green Line station and all LAX terminals via Aviation Blvd and the LAX Bus Center.
  • Detour Metro 232, Torrance Transit 8, and Commuter Express 438 to make stops pass El Segundo Green Line station.
  • Reroute Beach Cities Transit Line 109 to terminate at El Segundo Green Line station rather than at Aviation.
I can't comment upon frequency and duration of service of these line at this time.
