Metro Retires Last Diesel Bus

There's nice article from Steve Hymon at The Source on Metro's retirement of its last diesel powered bus (article link here). With this milestone, Metro becomes the only major transit agency in the country to have a bus fleet equipped entirely with alternative-fuel technologies. As the LA Times notes, the regional impact on pollution is significant:
In an urban area where diesel buses began operating in 1940, the MTA now has 2,221 buses powered by compressed natural gas, as well as one electric bus and six gasoline-electric hybrids.
Transit officials estimate that the elimination of diesel engines has reduced the release of cancer-causing particulates from the bus fleet by 80% and greenhouse gases by about 300,000 pounds a day in one of the smoggiest areas of the country.
Increasing mass transit ridership is undoubtedly one of the keys to making transportation and land use more sustainable for everyone in the Los Angeles region, but the way in which riders are transported is also important; a cleaner bus fleet is critical for improving for the public and environmental health of the region.

Design for Broad Museum Unveiled

The architectural design that Eli Broad is scheduled to reveal Thursday in a news conference at Walt Disney Concert Hall wraps the museum housing his contemporary art collection in a porous honeycomb. The billionaire collector and philanthropist hopes the $130-million building will help bring about his vision of downtown L.A. as a bustling urban hive of culture and street life.
The three-story museum will be known simply as the Broad, although the Broad Art Foundation is its formal name. The wraparound bonnet of interconnecting concrete trapezoids is courtesy of New York architects Diller Scofidio + Renfro.
Lead architect Elizabeth Diller's term for it is "the veil," because it enables the museum to relate to its surroundings by providing slots through which visitors can look out on Grand Avenue, and passersby outside the museum can get glimpses of what's inside. Visitors will enter the museum at ground level, take an escalator bathed in natural light to the top-floor galleries, and return via a staircase from which they'll have views into what she has dubbed "the vault" — the storage facility on the first and second floor that will house all the art from the 2,000-work collection that's not on display or on loan to other museums.
Coverage of the unveiling has been extensive thus far. You can read additional coverage from Curbed LAblogdowntown, LA Downtown News, and The Architect's Newspaper by clicking on the links and a review by LA Times architecture critic, Christopher Hawthorne, here.

Leaving an evaluation of the museum's green credentials for another time, the most significant planning and sustainability issue facing The Broad involves the transportation of the more than 500,000 visitors that Eli Broad anticipates will visit his museum and MOCA each year. Finding ways to ensure that these half million people do not all arrive by car is important for reducing congestion and pollution in Los Angeles. Of particular importance is the street widening of Grand Avenue from 2nd to 4th streets and the new public plaza proposed for the southern and western edges of the site. These two proposed improvements hold tremendous potential for enhancing the public realm downtown and making Grand Avenue more pedestrian friendly.

With the regional connector planning to add a stop on the backside of the museum, it is doubly important that the City leverage the proposed public plaza and streetscape improvements as a way to create a strong connection with the proposed station, inviting museum patrons from throughout the Los Angeles basin to arrive via mass transit instead of by car. See the regional transportation map below for the variety of different locations that one could take the train to Grand Avenue. The regional connector is poised for completion in 2019, six years after the The Broad opens.

Integrating Sustainability into Bus Shelter Design

Bus stations provide an open platform for layering multiple sustainable technologies in a single location. Installing photovoltaic panels on top of bus shelter canopies is one of the most common practices of sustainable bus shelter design. Some cities are also beginning to explore the possibility of using bus shelters to capture and manage storm water.
Solar-powered bus shelter in San Francisco
San Francisco is in the process of rolling out 1,100 new bus shelters that use roof top solar panels to run lights and power an on-site wifi network, which has the potential to provide significant coverage when expanded citywide. The creative repurposing of bus shelters as a platform for advancing environmental and social sustainability goals holds tremendous promise and is an area that is likely to see further innovation, particularly as bus rapid transit lines like the Orange Line (and future Wilshire Line) continue to attract riders.
Solar panels on bus shelter canopy in San Francisco
To understand the potential for leveraging bus shelters as a way to advance sustainability in Los Angeles, consider that Metro operates 15,967 bus stops throughout its service area. If the transit authority built bus shelters similar to those being used in Corona, which use roof top solar panels to feed 1,748 kilowatt-hours of electricity per year into the grid, it could generate roughly 27,910,316 kWh per year of energy. That's enough energy to power approximately 4,560 homes.

15,967 bus stops x 1,748kWh/bus stop = 27,910,316 kWh
27,910,316 kWh/6,120 kWh per LADWP res. customer = 4,560 households

With nearly sixteen-thousand bus stops in the Metro system, there's a tremendous opportunity to use these sites for producing renewable energy, showcasing local artists and providing other socially valuable services like wifi or way-finding information. Given DWP's target for renewable energy production (35% by 2030), the demand for renewable energy in Los Angeles is high and as local capacity for renewable energy production increases, there is less need for running expensive high powered transmission lines through sensitive environmental habitat.

Clearly Los Angeles could be doing more to deploy its own contextually sensitive design for sustainable bus shelters and leverage such a program to advance additional co-benefits for the region: "green" its transportation system, decrease carbon dioxide emissions, reduce storm water runoff, create jobs for the manufacturing and installation of new sustainable bus shelters, expand free wifi coverage, showcase local arts and culture, and enhance the dissemination of important public information.

Mapping America


The New York Times complied data from the Census Bureau's American Community Survey, based on samples from 2005 to 2009, and made it available through a fascinating interactive map, searchable by city or zip code. Search for your city or community here.

The America Community Survey is an ongoing survey, different from the decennial census that attempts to count everyone in America, that generates data every year through a statistically significant sample of the population. The data is used frequently by urban planners to plan investments, infrastructure and sustainable community strategies.

Here are two accompanying articles from the NY Times about the transition of immigrants to suburbia and the changing demographic composition of the New York City metropolitan region.

Mayor Wants to Make Homes EV Ready in 7 Days

While at the 2010 LA Auto Show, Mayor Villaraigosa announced that Los Angeles would streamline the permitting process so that owners of electric cars can have charging stations installed in just seven days. DWP is launching a customer hotline (800-342-5397) and the City created a new website (https://www.permitla.org) to expedite the permitting process.

As I argued in an earlier post, "not only have we dedicated enormous tracts of land to cars in the form of freeways and 6 lane roads, but auto-related infrastructure like gas stations also consume valuable real estate that would be much more productive as housing or neighborhood commercial/retail." De-centralizing the infrastructure needed to "refuel" cars will make it possible to re-appropriate gas stations for uses that are more socially, environmentally, culturally and economically sustainable and productive.

However, it would be nice to see the Mayor find a way to consolidate all of the city's numbers/websites and provide the public with a single, easy to use portal for accessing city-related information and resources. The good intentions of the city are often obscured by an overly cumbersome bureaucracy that makes obtaining permits, approvals, filing complaints or finding information a frustrating process. Streamlining the process for getting an electric car charging station installed in your home is great but I doubt many will hear about the Mayor's announcement, and those that do won't know where to look to find the hotline or website.

West Hollywood's Transit Future

A few things are now certain regarding mass transit in Los Angeles: the subway will be extended as far west as the VA hospital, the Expo Line will be extended to Santa Monica and the Crenshaw Line will connect the Green Line to the Expo Line via LAX. All of these projects are in various phases of approval, funding or construction and are likely to be completed sometime in the next 5-15 years, assuming the Mayor's 30-10 plan takes hold in the new Congress.

Since Metro chose not to include a transfer structure at Wilshire and La Cienega to serve a future subway extension into West Hollywood, the options for providing mass transit to West Hollywood residents are limited. The most viable alternative seems to be a northern extension of the Crenshaw Line, which would create a high ridership transfer point with the Wilshire subway before traveling to Hollywood/Highland via West Hollywood. See figure 1 below for route alternatives.
Figure 1
Demand for a mass transit line that serves the Beverly Center, Pacific Design Center, West Hollywood Library (under construction and across the street from the PDC), and Santa Monica Boulevard corridor is incredibly high. We need to double down on our existing and future transit investments (subway, Expo and Crenshaw) and leverage their construction for strategic enhancements to our transit network. Extending the Crenshaw Line northward through West Hollywood makes a lot of sense, for it would not only serve one of the densest and most vibrant cities in the region but it would also improve the connectivity and overall functionality of Los Angeles' expanding transit network.

LA River Vertical Campus

"A starkly modern grid-patterned skyscraper within the heart of Los Angeles, the Vertical Campus, designed by architects Gail Peter Borden and Brian D. Andrews, is a tower that 'engages urbanity,' and seeks to energize and engage the community by re-orienting the landscape from the city’s horizontal sprawl to a vertical complex.

The tower is located over the Los Angeles River, using the building’s base to generate hydroelectricity, and is a mix of residential, commercial, garden and civic spaces.

Instead of just being a skyscraper, though, the Vertical Campus seeks to help re-envision how to unite people through design, how to house new growth in an already dense city, and how to blend complex building systems to unite an existing complex urban fabric. The building will, through its design and also programmatic elements, be a literal bridge that unites the people of different economic and social classes that currently reside on the opposite sides of the river.

Wind turbines join the hydroelectric to provide energy, as does photovoltaic film; horizontal farms breed algae for energy use while hanging gardens grow vegetables and flowers for residents; rainwater is collected and purified; and all of the city’s transportation paths – bike, pedestrian, car, subway, train – run across the building’s base, unifying the building in another way with its landscape." (Source: eVolo)

Using planning and architecture, through thoughtful and provocative design, to connect disparate and geographically isolated socio-economic groups is fundamental to the social sustainability of Los Angeles. At the same time, the tower's use of existing on-site ecological and infrastructural resources, made possible by its near perfect location adjacent the LA River and existing bike, pedestrian and rail connections, make it a model for vertical sustainability and performance-based design.

Solar Freeways

A Swedish architect, Mans Tham, proposes covering the nearly 500 miles of freeway in LA County with solar panels. Tham's "Solar Serpents in Paradise" leverage the enormity and urban geography of freeways to produce something positive: locally produced renewable energy that can be fed easily into the existing grid, thereby reducing the need for environmentally destructive solar farms in the desert.
Just covering the 10 freeway from downtown to Santa Monica would produce enough electricity to power all the households in Venice. There is also the potential to provide electric charging stations under freeway over passes and to use the carbon dioxide rich air from the freeway to grow algae on underutilized shoulder space.
Regardless of what one may think of freeways, they are likely to remain part of the built environment for many years to come. But simply denigrating freeways as hulking concrete structures that divide communities and degrade local air quality ignores their potential for becoming part of the sustainability solution. Taking sunken infrastructure investments and repurposing them to serve current needs saves time, money, land and is probably the most effective way for existing urban areas like Los Angeles to transition into a more sustainable future.

Decentralized Energy Infrastructure

As electric cars and plug-in hybrids continue to increase their market share in the United States, efforts to decentralize the energy infrastructure for these cars will undoubtedly help make places like Los Angeles more environmentally, economically and socially sustainable. I first introduced the idea of decentralized energy infrastructure in an earlier post, "Greener Cars and Fewer Gas Stations." To understand the point I'm trying make, consider that the fewer of these we need...
Gas station in Los Angeles
...means more land is available for developments like this:
Sierra Bonita affordable housing in West Hollywood
And with more housing and commercial development like Sierra Bonita in the heart of the city means there's less pressure to continue building at the urban fringe.
Sprawl in Santa Clarita
I applaud GM for partnering with Envision Solar to install their solar-powered charging trees at GM dealerships. Each "tree" can generate enough electricity to fully charge one Chevy Volt in a day. Making these charging trees available for private residences is the next logical step to improving the urban landscape in Los Angeles and making the region more sustainable.
