Metropolitan Zone of the Valley of Mexico, 66 miles wide and 68 miles long. Top: hydrology and agriculture. Below: hydrology and urban systems. The Texcoco Lakebed is the large blue area at center-right / INEGI topographic charts. Maps by Gabriel Diaz Montemayor.

Last September, the Mexican government announced the construction of a new airport for Mexico City. The current airport is the second busiest, per number of passengers, in Latin America, just after Sao Paolo, Brazil. The airport was recently declared to be at full capacity. It has two runways that cannot be operated simultaneously and it’s surrounded on three flanks –north, west, and south – by dense neighborhoods. Along its east site, the airport is adjacent to the Texcoco Lake bed. There is no more space for growth, so a new airport is needed.

The new airport master plan, as presented by Sir Norman Foster and Fernando Romero from Mexico, the architects who won an international design competition, is located just 5 miles north of the current airport and will occupy 17.5 square miles of the Texcoco lake bed. The remains of this formerly grand lake covers some 50 square miles. Spared by urbanization but partially used for agriculture, the lake bed has both permanent and temporary water bodies. Although miniscule in comparison to the original lake system, the lake bed sits at the lowest part of the basin, helping concentrate and infiltrate water, supporting the unstable soils of Mexico City. The lake remnant protects the city from more flooding. And the water it collects keeps the city afloat by infiltration.

Mexico City drinks more than half of its water from the valley of Mexico’s aquifer. This valley is a closed basin draining serviced, storm, and waste water towards the Gulf of Mexico via a deep and massive underground system. The load pressing on this desiccated, lake landscape, along with aquifer exploitation, has led to Mexico City actually subsiding by over 30 feet in its central area in the last century.

A recent public presentation about the new airport plan failed to discuss how the project will address these critical environmental issues and improve water quantity and quality, support soils, recover wildlife habitat, and create a regenerative relationship between the city and its lakes.

There are ways landscape architecture can be used to help the lake system recover. Among some existing concepts is Ciudad Futura (Future City) by Alberto Kalach, Teodoro Gonzalez de Leon, their Autonomous University of Mexico (UNAM) architecture students, and other collaborators. Published in La Ciudad y sus Lagos (The City and its Lakes) in 1998, this project proposes the recovery of the lacustrine system through the construction of infrastructure for water management and treatment, the definition of active lake edges, the creation of new public spaces, and the development of a new airport as an island in a regenerated Texcoco Lake.

A more radical concept would be to turn the current airport into an ecological reserve and park, performing water and soil management and providing wildlife habitat. Parque Texcoco (Texcoco Park) by Iñaki Echeverria doesn’t address where to place a new airport though.

With the new airport plans, the Mexican government promises not only first-rate architecture but also a place that creates ecological value, largely through a 1,730-acre public forest. But it remains to be seen whether the new airport’s master plan project can create a reconciliation between the built and natural environments, and this project can become a global best practice from an under-developed country. The health of the underlying ecological systems must be considered. Let’s demand this happens.

portland

Pioneer Courthouse Square / Kenneth Helphand, FASLA

Portland, Oregon, is more than a trendy place to visit—it has long been ahead of the curve on urban design and sustainability, thanks to smart leadership and a willingness to experiment and innovate. The Landscape Architect’s Guide to Portland, a project by the American Society of Landscape Architects (ASLA), explains Portland’s cutting-edge approach to sustainable urban design.

The guide provides both Portlanders and the millions of tourists who visit Portland annually a deeper understanding of why Portland is one of the most livable and sustainable cities in the world. The guide is also meant to educate city leaders, urban planners, and designers across the U.S. and around the globe.

According to Mark A. Focht, FASLA, president of ASLA and first deputy commissioner of Philadelphia Parks and Recreation, Portland’s landscape architects have played a crucial role in making the city a better place to live. Their contributions trace back to the early 20th century, when the Olmsted Brothers laid out many of the critical urban plans and park system, and continue with today’s generation of landscape architects, who are creating waterfront parks, beloved urban plazas, and cutting-edge bicycle infrastructure.

“Portland’s designed landscapes are integral to its urban fabric,” says Focht. “Landscape architects have long played a major role in designing the city’s public realm, and the key spaces between buildings that serve as the connective tissue for communities. These spaces include parks, plazas, streets, and transportation infrastructure.”

Topical tours offer both printable bike maps and Google maps. The guide also includes tours by district. People will be able to view the guide on their smartphones, tablets or desktop computers.

The website was created by ASLA in partnership with its Oregon Chapter and 11 local landscape architects, who are designers of our public realm and leaders in sustainable design.

The guides are:

Brian Bainnson, ASLA, Quatrefoil Inc.
Bennett Burns, ASLA, independent landscape architect
Mike Faha, ASLA, GreenWorks, PC
Kenneth Helphand, FASLA, University of Oregon
Rachel Hill, ASLA, AECOM
Lloyd Lindley, FASLA, independent landscape architect
Carol Mayer-Reed, FASLA, Mayer/Reed Inc.
Jeff Schnabel, ASLA, Portland State University
Jean Senechal Biggs, ASLA, Portland Bureau of Transportation
Rebecca Wahlstrom, ASLA, Olson Engineering Inc.
Robin Wilcox, ASLA, Alta Planning + Design

The guide is organized by the facets of the sustainable city, with sections on:

  • The Built Environment – how building and landscape work together to enhance sustainability.
  • Food – how the city’s local food system works, from urban farms to “food cart pods.”
  • Energy – how Portland has among the highest renewable energy use in the U.S.
  • “Grand Parks” – how the original Olmstedian park system is still key to livability.
  • Health – how parks are designed for users with all kinds of disabilities, even Alzheimer’s.
  • “People Spaces” – how the city creates a sense of civic pride through its plazas.
  • Social Equity – how the city helps the homeless and addresses the impacts of gentrification.
  • Transportation – how Portland created one of the best-integrated, most people-friendly transportation systems.
  • Waste – how the city achieved one of the highest recycling rates in the country.
  • Water – how it led the country on green infrastructure.
  • Wildlife – how its park system also serves other species.

This is the third in a series of guides focused on sustainable American cities. The first, The Landscape Architect’s Guide to Washington, D.C., was launched in 2012, and The Landscape Architect’s Guide to Boston, was launched in 2013. They have been viewed more than 150,000 times to date.

Dogpatch Arts Plaza / CMG Landscape Architecture

Why hasn’t anyone thought of this before? At the EcoDistricts Summit in Washington, D.C., two urban innovators in San Francisco, the home of so many game-changing technologies, have come up with a truly brilliant idea: the Green Benefits District (GBD), a sort of green business improvement district, designed to facilitate community investment in new tree-lined streets, parks, and gardens. Michael Yarne, with Up Urban and Build Inc. and the creator of the concept, said the GBD in the Dogpatch neighborhood of San Francisco will also aim to improve the management and upkeep of neighborhood public spaces, which they say is currently done poorly by the city government. The GBD will be like the “Uber of public space,” meaning they are adding another layer of more convenient services on top of the existing baseline service. A GBD is needed because the city government is “stuck in the 1970s.” But the GBD clearly has higher aims than just better services: Yarne sees a future with local, distributed renewable energy systems and more.

With the help of Scott Cataffa, ASLA, a partner at CMG Landscape Architecture, Yarne is in the middle of a two-year process to prototype the GBD concept. It seems creating a new assessment district in California is not an easy thing, as you first need a BID lawyer, then need to get 30 percent of the proposed assessed district to agree to a petition, and then 51 percent of the “weighted property owners” to back the idea through a ballot. Only then will the state and city governments allow you to use tax revenue to meet local ends.

Dogpatch and NW Potrero Hill, which covers some 700 acres and contains 100,000 people, has a “rich industrial heritage.” Through a survey, Yarne and his team learned the area actually has 13 sub-neighborhoods. Some of these maintain a “gritty, marginalized identity.” In contrast, some neighborhoods have a high level of “social capital,” which enables more coordinated action. Yarne decided to start in the area with higher social capital, with a history of local environmental activism and ownership of public spaces. There, a “plucky, can-do” group of locals have wrangled the state government to let them build a park where where was once transportation infrastructure. But all their efforts are “taxing.” This community clearly wants “parks and open space preserved,” but what’s the best way to do this? The neighborhood decided to pool resources into a new GBD.

The GBD will “coordinate property owners and build trust.” It will be a non-profit, public benefit corporation with an elected board and annual oversight by the city legislature. The new GBD will be “small enough to enable trust to grow and will operate in a hyper transparent manner.” It will “use an experimental ‘it’s OK to fail’ approach and aim to create long-term revenue.” Trust, he said, is the new “green,” because, without it, community action is impossible. Trust building will happen on the ground, in person, but also through a new app that will enable all GBD members to see in near real-time all reports, decisions, and expenditures.

“Like Facebook, the app will encourage GBD members to create a profile to encourage community accountability.” There will be something like the “See, Click, Fix” app, which will enable community members to report problems. The app will define the “party responsible for fixing, set the fix date, and the cost of the fix.” Yarne said listing the cost of the fix was important, because people don’t really have a clue as to cost of public services. All of the issues will be mapped, so the GBD member can see problem areas. For example, they could learn that vandalism occurs near the train stations. Like other techno-utopians in San Francisco, Yarne believes the app will “empower the community by demystifying work that’s happening.”

Landscape architect Scott Cataffa has been helping the nascent GBD map all their assets and discover where the opportunities are. Cataffa said a map of the community found only 2 percent of it is open space.  The community is already maintaining about half of the public spaces in the district, but the audit is helping the community figure out who owns what. With a list of more than 50 possible opportunities in hand, the GBD team is now figuring out what role they should play in creating new green public spaces and other sustainable features. They created a checklist to help label each project, with potential roles such as “lead, initiate, assist, or advocate.”

One proposal by CMG would create a new amphitheatre and outdoor art gallery in an unused, city-owned dead-end between two large industrial buildings. Through the audit, they also found that the very wide rights of way, which were designed for industrial use, create opportunities to create new linear parks. So they propose creating a new linear park — or green street — running from the new amphitheatre to a larger park. Cataffa said “we are looking at the right of way as a place to turn grey to green.” Other ideas being cooked up include putting a solar farm on top a freeway that cuts through the district, and creating a (black) waste water recycling system.

If they are allowed to assess the community for the GBD, Yarne says they will raise about $400,000 in their first year from taxes of about 9.46 cents per square foot of commercial and residential space and parking lots. Some non-profits would get a 50 percent discount on that tax, as would some struggling industrial site owners. Yarne expects their available funds to double over the coming years given lots of new residential complexes are coming online. He said, already, the GBD can change perceptions of new development from an unwelcome sign of gentrification into new opportunities to green.

ASLA 2011 Professional General Design Honor Award. Central Wharf Plaza by Reed Hilderbrand / Charles Mayer Photography

Do sustainable landscapes live up to the lofty goals promised by landscape architects? How can we know? I am investigating this with University of Oregon professor Chris Enright in the department of landscape architecture and professor Yizhao Yang in the department of planning. I want to understand the role of post-occupancy evaluation (POE) in the field of landscape architecture. Though environmental, social, and economic performance goals are often identified during planning and design stages of landscape projects, most lack effective post-construction monitoring and observation to determine if — and how well — project’s design goals are being met.

Evidence-based design has gained more attention since the International Federation of Landscape (IFLA), the ASLA, and Council of Educators in Landscape Architecture (CELA) identified the topic as a research priority. The Landscape Architecture Foundation (LAF)’s Case Study Investigation (CSI) program—born out of a need to encourage and support design firms in assessing the performance of sustainable landscape projects—is now in its fourth year. And now many leading firms are increasingly investing in in-house research on performance. Yet little is known about perceptions of POE within the profession as a whole.

So I invite landscape architects and others interested in landscape performance to participate in my study by taking a brief survey. I will report back the findings of this survey on The Dirt.

As a second part of my research, I will examine Facilitated Volunteer Geographic Information (F-VGI) as a tool for POE by comparing it with traditional approaches like direct observation and intercept surveys. I want to see how well-suited F-VGI is for post-occupancy landscape performance analysis. This technology increases the capacity for analysis by crowd sourcing data collection to users. The process is also relatively low cost, offers the opportunity for longitudinal study, and could be more objective than traditional methods, since there is less chance for bias from volunteers.

Using a project by landscape architecture firm Reed Hilderbrand, Central Wharf Plaza in Boston, I am developing a framework for using F-VGI to evaluate landscape performance. I chose this project because it already established social, economic, and environmental performance goals and baseline data. It’s a high-traffic, urban site with a public audience. Central Wharf Plaza has a simple but clearly defined program, and it’s small enough in size for a person to objectively evaluate the whole site.

Next Generation Infrastructure / Island Press

Between crumbling bridges, rising sea levels, growing garbage piles, and the ravages of drought and storms, we’ve grown used to bad news when it comes to infrastructure in the United States. Old systems are failing, new challenges arising, and solutions are elusive or perplexing. Into this maelstrom enters Hillary Brown, architect, infrastructure consultant and professor at the Spitzer School of Architecture. Her new book Next Generation Infrastructure: Principles for Post-Industrial Public Works, is an inspiring argument for infrastructure that behaves like nature.

Armed with simple prescriptions, Brown argues that the next generation of infrastructure cannot resemble the hard, single-function and carbon-intensive structures of yore. Rather, we need “more diversified, distributed, and interconnected infrastructural assets that simulate the behavior of natural systems.” She walks us through the principles of a new ecological infrastructure piece by piece, with abundant case studies that show that ingenious, multi-purpose, carbon-neutral, resilient systems are not a pipe dream. She pays careful attention to how they were implemented, reinforcing the argument that these case studies are models that can be applied beyond their exceptional contexts.

On a world tour of next generation infrastructure, Brown stops to describe ingenious feats of co-location, “decarbonizing” infrastructure (that is, infrastructure which emits low or no carbon), and soft-path water systems. Highlights include a Malaysian automobile tunnel that retains stormwater, a French waste recovery center that powers public buses, and a Northern California wastewater treatment wetland that also provides walking trails and wildlife habitat.

Other chapters emphasize resilient infrastructures in the light of the paradoxical abundance and scarcity of water facing areas around the globe. The clever, even artful, solutions to what seem like insurmountable solutions make for an inspiring read, even if the black and white illustrations and (unfortunately not very clear) flow charts breaking down complex loops and systems are not in the same spirit.

Particularly notable in an era of tight budgets and low expectations is Brown’s attention to the social aspects of infrastructure planning and design. An important part of her problem-solving focuses on combining amenity with utility, and close attention to siting and design. This is not only important to make sure that particular groups do not unfairly bear the brunt of everyone’s waste, water, and energy systems needs. People living near such projects can benefit from the community assets, not to mention new jobs, that new infrastructure can provide.

In this regard, but not only in this one, Brown argues that design is key. The design implications of co-location and systems thinking are huge, as are the opportunities for landscape architects, architects, and planners. Integrative thinking, cross-disciplinary design, and spatial imagination are essential for developing the next generation of ecological infrastructure. A leading role for designers is another piece of good news in an area often lacking for it.

Ecovative natural Styrofoam / Greener Package

The Buckminster Fuller Institute is looking for solutions to the world’s toughest problems. They just released the call for entries for their 2014 Fuller Challenge, “socially-responsible design’s highest award.” Landscape architects, architects, planners, artists, entrepreneurs, and students from everywhere are invited to go for the $100,000 prize for most outstanding strategy.

Buckminster Fuller, who died in 1983, was way ahead of his time. While he is famous for his geodesic dome, which took form in Disney’s “Spaceship Earth” Epcot Center and other buildings, as well as his innovative maps, Fuller’s deeper impact may be on our thinking. He was one of the first modern Western thinkers to connect architecture to ecology and the environment.

According to the institute that bears his name, Fuller called for a “design revolution to make the world work for 100 percent of humanity, in the shortest possible time, through spontaneous cooperation, without ecological offense or the disadvantage of anyone.”

This worthy goal is now being pursued through the Fuller challenge, which seeks to identify global change-makers. Winners haven’t just taken on a building or landscape but a whole broken system.

Last year, an amazing group of materials innovators at Ecovative took home the prize for their game-changing Styrofoam made of mycelium and agricultural waste. The year before, the Living Building Challenge won for showing the world how a green building could become a self-sustaining system.

Submit your concept by April 11, 2014.

Another competition is a bit of good news for Ukraine, which faces challenges on so many fronts at the moment. A new ideas competition from the Can-action 2014 festival will award 5,000 EU for the best user-generated public space concept. Chinese artist Ai Wei Wei is one of the judges. Submit ideas by April 17.

Mark Simmons sets fires. He uses prescribed fires as a technique for land management to improve the ecological health of a system. These fires are carefully plotted and designed to self-extinguish. They are employed to control brush, which could feed wildfires, and selectively remove invasive species and restore native ones. Simmons is the director of the ecosystem design group at the Lady Bird Johnson Wildflower Center at The University of Texas. His team engages in scientific research, sustainable design, and environmental consulting.

American Indians on the plains also set fires. They used controlled burning to both attract and drive game, get rid of ticks, and harvest lizards and insects. Simmons says this practice demonstrates that they had a mutually influential relationship with nature. They melded the landscape and in turn were melded by it.

Americans today are found in different landscapes. We primarily occupy landscapes like suburban strip mall parking lots, which Simmons believes are dysfunctional and polluting. If these landscapes are melding us, then they may be adversely affecting our health and behavior. He believes that providing more green spaces could control epidemics like childhood obesity and ADHD.

In order to combat environmental and social hazards, Simmons wants to bring nature back into the built environment using ecological design. He envisions an “eco-metropolis” in which we keep, fix, and build using “nature’s technologies.” Simmons believes these approaches can inform techniques for land management and restoration, as well as the research and design of greenroofs and walls, rain gardens, sustainable lawns, and ecological roadsides.

Our current situation is about maintaing an “industrial, not ecological, system on life support,” Turf grass covers 40 million acres of land in the U.S., with 20 million acres just residential lawns. This landscape requires 580 million gallons of gasoline and up to 60 percent of urban fresh water to maintain. Desert communities have begun banning lawns out of necessity. Simmons finds gravel lots and other available alternatives lacking in both functionality and aesthetic quality. He is promoting alternatives that are sustainable, useful, and desirable.

Simmons grew up mowing his family’s lawn in England with a push mower. His dad no longer needs to mow because the lawn is now a multi-species landscape that has evolved into a stable ecological system that maintains itself. Inspired by this discovery, Simmons and his team created a biodiverse lawn made up of five native species that only has to be mowed two to three times a year and does not require pesticides or herbicides. There are eight acres planted at the George W. Bush Presidential Library. Simmons calls this “ecology 101 applied to landscape architecture.”

Landscapes like Simmons’s lawn that deploy nature’s technologies can perform critical functions like carbon sequestration, low level ozone absorption, and stormwater management.

Grasslands in fact provide the most efficient means of carbon sequestration. They absorb less carbon dioxide than boreal forests, but because they have evolved with fire and grazing, they store 95 percent of it below ground as insurance. In contrast, trees store carbon dioxide above ground in their trunks, branches, and leaves and release it back into the atmosphere when they die. In grasslands, when the roots die, the carbon melds with the physical and chemical structure of the soil and can be held there for hundreds of thousands of years.

These landscapes are also desirable. Simmons shares several examples of their success and growing popularity. Residents of a suburban tract in Austin, Texas liked the prairie that was planted along the perimeter so much that they requested it be continued through their yards. A homeowner who wanted a meadow constructed on his roof is so pleased with the result that he supports the idea of creating a preserve of the Texas blackland prairie ecosystem on roofs and along roadsides.

Simmons demonstrates that we can use nature differently. He encourages us to preserve nature but also feel liberated and empowered to use it more like we would engineering. “Nature’s technology is free and it’s waiting. All we have to do is bring nature home.”
