"“All great art is born of the metropolis.” - Ezra Pound

 :: image via NY Times


A great little snapshot on urban serendipity from the NY Times that looks at the accidental 'curation' of spaces that the urban environment yields, such as the framed view from the subway to the Brooklyn Bridge.  Perhaps the uniformity of the grid is part of the magic, as the NYT also talks about the 200th Anniversary of the Manhattan Grid, along with the exhibition at the Museum of the City.  And speaking of paving here in Portland, local group Depave got some nice coverage on OPB for their continued work on rolling back pavement in the city.  As for making money on the urban agriculture and gardens - a study in Vancouver, BC finds that it is still a challenge to make a living wage farming, even in the city.  Perhaps we can lobby for urban farm subsidies?

Nate Berg at the Atlantic Cities sums up Los Angeles Times architecture critic Christopher Hawthorne's year-long project to explore his city through its literature, and some of his conclusions on where we stand.  As quoted in the Atlantic article:
"“What the books have suggested to me,” Hawthorne argues, “is that we really don’t have – and need – a new framework for understanding the city at this moment in its history as it undergoes this transition.”
A review of his most recent reading of 'Los Angeles Plaza: Sacred and Contested Space' can be found here - which is an interested exploration of the role of space, and the role of social status, on the way we interpret urban histories.  Related, and probably not big news, but people are less enamored with the suburbs, and are re-urbanizing, in this case, Philadelphia along with living in more dense types of housing.

More on Occupy, with the recent flurry of Global and US occupations bringing into question the 'limits' of how public spaces are.  As mentioned in the story:
"The Occupy Wall Street movement showed there are often limits to how long one can stay in the town square of a “free” state to express one’s opinion. Various kinds of force were used to get people out of New York’s Zuccotti Park."
An interesting article from The Dirt on the $50 million!!!!! dollars of planning documents and designs for the Orange County Great Park, which has failed to yield much in terms of output.  It brings into question the time-scale on these massive endeavors, and how much needs to happen to create a 'park' in a traditional sense to satisfy some - while allowing space (and budgets) to evolve over decades.


:: image via The Dirt


Finally, a new competition from the Land Art Generator Initiative asks how renewable energy can be beautiful with a planned site at the Freshkills Park - which has a similar time-scale to the Great Park above.  And Freshkills may be an apt model for Mexico City, who is planning to close their massive landfill... And for the squeamish, a new report from the National Research Council changes the tune of reclaimed wastewater (aka toilet to tap) from a 'option of last resort' to a viable strategy that poses no more health risks than other sources.  Drink up!

Black Rock City

An interesting article making some strange connections between the land of free spiritedness that is Burning Man, specifically the arrangement of the temporary settlement 'Black Rock City' with the ideology of New Urbanism.  I can't think of two uniquely different mind-sets and approaches, so find the connection to be somewhat comical - but am keeping an open mind.  So read for yourself... and determine perhaps if that next vacant town square surrounded by walk-up townhouses would benefit from an iconic super human sculptural icon that regularly is set aflame?  Maybe it would be a Waldheim effigy?  Who knows.


:: image via NY Times

A snippet:
"One of the many ways in which Black Rock City epitomizes thoughtful city planning, Mr. Garrett said in a 2010 interview, is that people are responsible for managing their own waste. (“Leave no trace” is a Burning Man mantra.) Another is that cars are sidelined, thanks to a layout that makes walking and biking far less onerous than driving. In that approach Mr. Garrett had allies among the New Urbanists, the town planners sometimes labeled reactionary for promoting quaint enclaves like Seaside, Fla. He also had a soul mate in Janette Sadik-Khan, New York City’s transportation commissioner, who is responsible for closing some streets to vehicular traffic"
I was interested in hearing that Rod Garrett, who was asked to lay out the plan - and his experience as a landscape designer... creating something both flexible yet keeping a tight footprint with an awareness to the overall ideas of circulation.  A quote from a obit on Garrett, who recently passed away, comes from Yves BĂ©har, "...design professor at California College of the Arts and a 5-year veteran of the Playa himself, described Mr. Garrett as "a genius", explaining, "A circular temporary city plan built around the spectacle of art, music and dance: I wish all cities had such a spirit of utopia by being built around human interaction, community and participation."

RBC: Zeekracht (OMA)

Zeekracht | OMA

A related follow-up to the essay by Koolhaas, this short essay explores Zeekracht, a master plan for the North Sea, driven by it's "high wind and consistent wind speeds and shallow waters..." making it "...arguably the world's most suitable area for large-scale wind farming."  The project master plan (below) outlines the strategy.  "Rather than a fixed spatial plan, proposes a system of catalytic elements, that, although intendted for the present, are optimized for long-term sustainability." (72)



From an ecological perspective the proposal looks to incorporate elements call 'Reefs' which are described as "simulated marine ecologies reinforcing the natural ecosystems (and eco-productivity) of the sea." (72)


The local implementation is "...designed to be sited, programmed, and phased to meet the evolving demands and plans of North Sea regional development," fulfilling the potential of the area as "...a major player in global energy production and trade through wind power alone." Aside from the energy potential, there is the idea thinking of this in tandem with ecological restoration, as "Farms developed along ecological zones and around existing decomissioned platforms create marine remediation areas, new recreational parks, and recreational sea routes." (72)



The project offers the example mentioned by Koolhaas as a "combination of politics and engineering" (71) that is essential to attain and ecological urbanism, attaining both productivity and remediation:

Guest Post: The Human Benefits of Green Building

by Krista  Peterson

While it may initially seem like the only benefits of “green building” efforts go to the environment – at the cost of human comfort and expense – this is not the case. Proponents of eco-friendly architecture take a holistic approach to the concept of environmental health, including human well-being in their calculations. The U.S. Environmental Protection Agency lists three goals of green building programs: to increase efficiency in the use of water, energy, etc.; to protect the health and increase the productivity of the building’s residents; and to reduce pollution and waste.

Greater Efficiency

According to the EPA, in 2002, buildings accounted for 67.9% of the total electricity consumption in the United States. It has been said many times already, but decreasing energy use is not only good for the environment – it’s good for the wallet. When a building is more energy efficient, less HVAC (heating, ventilation, air conditioning) equipment is necessary. Since heating and cooling the air accounts for roughly half of a building’s energy expenditure, improving efficiency can significantly reduce operating costs. Other small measures, such as upgrading insulation and sealing any air leaks, can make a big difference in a monthly electricity bill.

The high costs commonly associated with going green are usually a result of installing new technology in a new building or retrofitting an older one. On-site renewable energy generators from sources such as photovoltaic solar panels or wind power can include prohibitive start-up costs and may not be feasible for every structure. However, efficient appliances with the Energy Star label often cost the same as traditional appliances, and installing ceiling fans to reduce the need for air conditioning is a simple step that makes a measurable difference. For new buildings, passive solar heating principles that take advantage of the orientation of the sun and the landscape go a long way toward improving energy efficiency.


Better Health

Another goal of green building is to improve air and water quality within structures, as well as the productivity of their occupants. One EPA report states that indoor air pollutant levels are about two to five times higher than those of outdoor air. Some of these pollutants, such as radon gas, are attributable to natural conditions, while others such as second-hand smoke are a direct result of human behavior. However, many of these pollutants are a byproduct of the materials used to construct or furnish the building. Volatile organic compounds, or VOCs, can cause serious health consequences in large enough concentrations. These chemicals may occur naturally, but they can also be manmade, and are found most commonly indoors in products such as paints, solvents, carpets, cleaning products, and some household appliances.

Asbestos is another dangerous pollutant. While this thread-like mineral is no longer used in the manufacture of new building materials, it was widely used in nearly every aspect of construction until the 1980s and can still be found in most of these buildings. When breathed in or ingested, asbestos fibers can cause serious health problems such as lung scarring, asbestosis, and mesothelioma cancer. Mesothelioma symptoms include shortness of breath, coughing, and pain in the chest, very similar to other, less fatal lung conditions, which can mean that the cancer often goes undiagnosed until its later stages. Green building efforts take into account the human costs of building with certain materials – though asbestos makes for an effective source of insulation, it is severely dangerous to a structure’s occupants, and thus alternative materials are used instead.


Less Waste


One simple way that green architecture produces less waste is by using renewable materials, such as plant matter and sustainable lumber, or reusing traditional materials, such as recycled stone or metal. It is even possible to reuse industrial byproducts like coal combustion products, foundry sand, and demolition debris. Ecologically responsible construction can also help the occupants of the building waste fewer resources when going about their daily lives – greywater can be used as irrigation, or treated and used for other non-drinkable purposes.

Moreover, green building furthers the concept of “smart growth,” an umbrella term for architecture and urban planning that takes into account sustainability, human health and safety, and economic expansion. It is not enough to simply substitute one building material for another; an entire change of outlook is necessary if we want to be able to sustain our quality of life, and green building is one way to start. The benefits are highly visible – mesothelioma symptoms, for example, can be prevented almost entirely by avoiding exposure to asbestos. Looking beyond individual health, the EPA estimates that buildings contribute 38.1% of the country’s carbon dioxide emissions, but this figure can be reduced through the use of environmentally responsible architecture and urban planning.

Aquifers not Aquitards

From the recent post on watershed boundaries, a reader mentioned the concept of underground aquifers and their relation to geographical boundaries and .  My title is in jest (sort of) referring to 'Aquitards' which according to Wikipedia is "a zone within the earth that restricts the flow of groundwater from one aquifer to another", but I thought an apt metaphor for our overuse and depletion of these amazing resources.  So in a crude analysis, the map of US aquifers is pretty amazing (here's a comparison of 'watersheds' and 'aquifers' in two maps with some context of states and cities (images from National Atlas mapping tool)

aquifers

watersheds

While many aquifers develop in tandem with surface waterways, others are disconnected from these sources giving them different patterns.  Ancient sources are often tapped, with draw-down causing these to be depleted much faster than they are recharged.  One of the most familiar, the 10 million+ year old Ogallala Aquifer (synonymous with 'High Plains Aquifer') that supplies water to the agricultural bread-basket of the world - centered in Nebraska and spreading from the southern tip of South Dakota into the northern panhandle of Texas.  


:: image via Wikipedia

I hadn't considered the number of aquifers and their distribution (another great tool is an online mapping application from National Atlas, found here), but it's interesting to see the difference between more broadly based, central aquifers (not specifically linked to a river) like the Ogallala, or in Oregon the Pacific Northwest Basaltic rock aquifers (unlike the Columbia River based systems to the north.  These more agriculturally oriented aquifers can be compared to small scale aquifers like the Biscayne which supplies drinking water to much of Central Florida.

:: image via USGS

The interactive mapper allows you to zoom in on state & county boundaries, as well as locations of significant cities, to see the relationship of urban agglomeration to aquifers, for instance a closer look at the area centered on Chicago (mapped from the National Atlas).


The cause and effect of cities and aquifers is probably more significant in the impacts of urbanization on water supplies (both through depletion and pollution) and the delicate interaction between surface and subsurface conditions.

:: image via Wikipedia

While subsurface conditions do exist separate from visible surface conditions, there are impacts as many rivers as charged with these underground sources, and depletion (and diversion) has caused some rivers to no longer reach the oceans - such as the Rio Grande and the Colorado (anyone guess the reasons) or the filling of traditionally large reservoirs like Lake Mead and Powell - creating significant water scarcity issues in certain metropolitan regions.  Another great lens to look at cities, so more on this to come... seems the hydrological cycle is tied to everything we do.

Environmental Urbanism Panel Discussion

As an addenda to the previous post, on Chris Reed's lecture, a round-about summary of the panel discussion that followed.

Panel Discussion - Environmental Urbanism: 
Ecological Design for Healthy Cities

The panel was moderated by Peter Steinbrueck, with Reed joined by additional panelists including Randy Hester (who lectured the previous evening on Design for Ecological Democracy) and Frumkin (newly installed as Dean of the UW School of Public Health).  Definitely a diverse group which ranged into ecological democracy and public health, paired with Reed's landscape urbanist approach - which offered a potentially interesting exchange of ideas, the result was less than satisfying.  A summary of some of the highlights.

The Potential for Public Health (HF)

Dr. Frumkin has written quite a bit recently about Biophilia and it's usage in a wider arena of public health, and started the discussion with a summary.  The evolutions from Environmental health (dealing with Toxicity), Urban health (focused on the urban poor), and Health Promotion (typically behavioral changes) could be married to create a new approach to urban environmental health.

The key concepts necessary for this were response to equity, considering differing health disparities, and the development of a viable body of evidence-based design strategies (proven through scientific methods) that achieved the dual public health goals of efficacy and safety.  He mentioned that design, although backed with some new environmental science, is not evidence-based, and this would make it difficult to convince public health officials of its worth, due to lack of scientific data.  While Frumkin's ideas of expanding the realm of biophilic design and evidence-based concepts to cities was interesting, a quick reading of some of his reading work shows that a mere translation of site-scale biophilic concepts to public scale is difficult.  The other issue is that there is a definite problem with balancing the cultural aspects of design with the scientific models - to avoid a overtly deterministic reading and application of ideas.

Design for Ecological Democracy (RH)

Not having a chance to hear Hester's talk from the previous evening (and only having skimmed his new book) it's difficult to capture the essence of his idea, but as he mentioned - it involves design that supports values, specifically democracy, equity, access to nature.  As he mentioned, in this context, place matters, and he outlined 3 approaches:

1. The Uniqueness of Place matters to our health (there are different flavors of democracy, much like there are different systems of ecology.
2. Awareness of Personal Ecology: Design and form matters
3. Applying Democracy and Ecology - both can be informed by key principles but are influenced by external forces (for instance free-markets) which augment their level of success.

Our typical mode of operation currently, in an age of consumerism, is that we get democracy, but rarely give back to it - and similar factors are at work in our relationship with ecology.  Take but no give.

Natural Processes & Community (RH)

Requires understanding through experience, ecology of knowledge which leads to stewardship. access to wild nature, but innately this has little evidence (other than anecdotal study - nature=good).  Connecting this back to design, Hester mentions that access to constructed nature, we want to experience nature, but also appreciate the mentorship of the designers intervention - teaching through design.  In this way, we can connect something simple, like a species of bird, to a much larger process of ecological function.

Interaction with Ecology (CR)

Reed mentions that one aspect is that it isn't a duality of nature/city that we need to provide access to, but to provide the same range of interactions to those inside the City... He defines three concepts 1) Wilderness preserve - outside; 2) Central Park - cloistered; 3) interactive ecology - inside and incorporated into the fabric of the urban area.

Landscape Urbanism Theories (CR)

The question posed was how did these connect to public health, but Reed strongly cautioned against a focus on evidence - arguing for the cultural aspects of design that can't be quantified.  In his terms, the concept of health is closely tied to ecological principles of the work - such as survivability and resilience - things found in healthy ecosystem.  Most interactions with nature are anecdotal, and the research should fit within design strategies of diversity and choice for users.
The project work, particularly small scale solutions, involve the testing of theories in metropolitan environments, trying out ideas, innovations, materials, and venues - and experimenting with small-scale ecologies.
The project work, particularly small scale solutions, involve the testing of theories in metropolitan environments, trying out ideas, innovations, materials, and venues - and experimenting with small-scale ecologies.  He mentions the role of the designer changing to accomodate monitoring over time, with landscape architects taking over more roles and responsibilities.

He also mentioned the upcoming ideas of Corner's work on the Seattle Waterfront, an opportunity to apply some landscape urbanism principles (but something developed in context).  The major opportunity is to rethink large scale systems, and redirect existing resources (waste heat, stormwater) in looped systems available in urban agglomerations.  In short, it becomes a wholly economic idea to push an ecological concept because they have value that needs to be quantified (this is where we need evidence)

Unified Field Theory of Public Health, Ecology, and Landscape Urbanism (all)


Frumkin:  Sustainability is a model - 3 legged stool and ability to specify outcomes to acheive prosperity, equity, and social goals.

Hester: The Intention of the System - develop a shared language; there are three different languages that exist: 1) those that are different, 2) those that are words for the same thing (different disciplinary languages - potential for obfuscation), and 3) those that are purposely convoluted (making something simple sound very complex - which leads to it being the next hot thing.

Reed:  Defending language, there are many ways to use it which are all appropriate (public, private, academic) - these different modes have the same principles.  We talk in public in pragmatics (design informed by professional perspectives, using disciplinary language, a different language for structuring projects and frameworks for projects,  They are in competition, but able to co-exist.  Rather than focus on language, Reed sums up the point (in what I think is the best quote of the day):
"The goal should be to use social/ecological dynamics that are flexible for futures we can't imagine."
Planning for these Spaces (CR)

There is the need to determine what we know, and what we can't know - thus the need for open-ended projects.  Some models of determination include preparedness planning - looking 30 to 40 years into the future to plan for spaces.  This will involve working at a wide range of scales - with a range of resources, for the entire lifecyle

Ephemera

  • Need to plan for aging populations - loss of ability to drive and less mobility (HF)
  • Look at co-benefits of designing for the old, the young, the disabled - all with specific by interrelated needs for space (RH)
  • The approach to research/evidence based design requires new ways of working together, identifying which types of issues to accomodate (HF)
  • Define the outputs for a range of systems, redirected within the city (CR)

Summary

Honestly, what could have been a really engaging dialogue of disparate (but related ideas) was somewhat handicapped by poor choices of questions from the moderator and audience led to a mishmash of  concepts - rather than a response and relation to the topics offered by Reed (which I guess I was predisposed to want)... the divergence from the original presentation was problematic, and the trying to tackle public health, ecological democracy, and landscape urbanism under a wide banner of 'Environmental Urbanism' left me feeling like in trying to do it all, nothing was accomplished.

While Frumkin had ample time to offer thoughts on public health implications, the focus on evidence based design was not fully discussed, and was divergent from concepts of ecological democracy (at least in this context.  Perhaps an all day exploration would yield results, but a short panel discussion was not enough to even ask, much less discuss, many of the relevant questions.

Parsley On the Building

A great overview on Urban Omnibus features some of the recent site specific events in the 50th Anniversary of the GSD celebrating the half century of urban design (which at least in a modern perspective evolved from Harvard and mid-twentieth century theorists).  While the author seems to incorrectly equate concepts ecological urbanism and landscape urbanism, and does reinforce some anti-density precepts that have been tacked on to landscape urbanism, the overall tone is pretty evenhanded and worth checking out.  My goal here, then, is not to rehash the recent 'wars' which have received a ton of attention, but to point out a few new conceptual tidbits worth exploration.  The first one that got me a bit riled was attributed to Duany in the following paragraph:

"It is probably best that these two urbanisms are fighting to dominate intellectual territory of urban design, for both will be necessary to promote real sustainable solutions. This was made quite clear when Duany suggested that the best use for Ecological Urbanism was biophilia: greening buildings to make them more aesthetically pleasing to the middle class."
Yes, biophilia is a powerful concept that will continue to become more integrated into landscape and architecture and urban planning, as a metaphorical and formal framework to achieve needed access to nature (both visual and physical).  The fact that this becomes Duany's 'best use' for ecological urbanism, making buildings palatable for the middle class, definitely counts as another over-simplification at best.  While the notion of the vegitectural as aesthetic 'parsley on the building' has definitely become commonplace with architects - at least in photoshopped forms (it has also been vilified, rightly so, for it's simplication as inert green garb - used as an inert architectural material, applied like any other inert material) - preferrably for architects in a aggregated 'system' that can be specified and purchased on a square foot basis.

There is an innate ecological value in the process of attaching vegetation to buildings, so to reduce it to aesthetics is belittling both that value and the value of those working in these areas of practice.  One aspect of a true ecological urbanism would be to incorporate not merely biophilic (which is valuable, but non-performative), but bioclimatic principles (incorporating ecological systems into the fabric of building systems to augment and replace mechanical systems, improve indoor air quality, increase comfort, and provide myriad other benefits beyond those of the biophilic).  It can't just be appliquĂ©d - but rather must be integrated, using interdisciplinary approaches (not photoshop) resting on ecological principles.  The result is centered on building users, environmental concerns and reduced impacts to natural resources, and a vital connections to local context that is necessary for optimum performance.

The second quote involves the framing of NU for sustainable urban design.
"... Duany listed three reasons why the recent financial and intensifying environmental crises favor New Urbanism to offer sustainable urban design solutions. First: peak oil will make it more costly to drive, thus favoring creation of the dense, walkable neighborhoods advocated by New Urbanism. Second: the mainstay metric for ecological footprint analysis is carbon emissions, which will incentivize walking and public transit over cars as favored modes of transportation. Third: the residential, mixed-use typologies championed by New Urbanism were too complicated to be included in the mass securitization of mortgages and thus were resilient to the housing crisis."
The concepts of adaptability and indeterminacy (and I'd say, a renewed focus infrastructure) will have more benefit than those of New Urbanism in responding to peak oil, as although we can see the crisis looming, we have no way of predicting what impact it will have on cities, and the impacts of individual investigations at a site scale will be minimal.  While the 'nifty' six point plans for suburban retrofits make for good soundbites for new sustainability initiatives and plans for reducing ecological footprints, they involve a recontextualizing of the same principles, not a reformulating of an approach to urbanism.  Yes, we will fight out the new urban condition in fields of grey and brown, but will: "...restructuring and redevelopment of suburbia - so that retrofitted centers are walkable, diverse and environmentally sustainable..." actually mean anything substantive and repeatable beyond a few American enclaves... while the rest of the world decays at an alarming rate and at a vastly different scale.  Furthermore, the typologies mentioned I'd say were immune to the mortgage crisis purely due to lack of affordability, as those buying these houses are not those specifically impacted in the economic malaise. The packaging and reformulating of the ideas will provide some solutions to these crises, and incorporating walkability, diversity, and sustainability are laudable goals.  But with few viable and repeatable examples (particularly in terms of diversity) so far realized, making it's tough to see how this will be 'the' solution.

Talking 'bout My Generation
I found it doubly interesting, to put it in perspective, that the GSD Urban Design Program is 50, the principles of New Urbanism recently turned 30, and the theories Landscape Urbanism barely clocks in over 10 (a wee bit over perhaps)... give or take a few years a span of a generation between each.  Take in for a second the concepts of maturity and growth, as new concepts are born, learn, adapt, and mature - sometimes rigidly dismissing their elders, often becoming a new hybrid 'adult' formulation worthy of adoption or dismissal.  While I'd love to say my 10 year old self was correct, it would be good to note how these ideas have changed and grown (for instance, new urbanism developing a much more successful concept of sustainability long after it was 10 years old), or urban design learning from 'modernist' experimentation (success and failure), incorporating new ways of seeing cities, such as those of Jane Jacobs) and developing a level of maturity.

Much as new urbanism did not throw out the foundations of urban design but framed them in specific ways, landscape (and ecological) urbanism does not aim to disregard a history of theory and practice gleaned by many professionals over the years - but rather aims to re-evaluate these principles through new lenses.  These lens promote sprawl or focus solely on infrastructure.  They also don't preclude walkability, cities for seniors, appropriate density, or 'practical patterns of human settlements' - but rather acknowledge a  reality that is complex beyond a simplified deterministic approach.


I'd like to agree with Michael Sorkin's point in Urban Omnibus that we can merely use the lens of humanity, equity, sustainability, and beauty (all good concepts that seem aptly homogenized in reductive strategies like LEED) but perhaps we need these arguments to frame a real approach to urbanism that is both realistic and beneficial to all.  Maybe not calling it anything (although that seems hard to market) would be helpful, but I think we all still project and promote urbanisms as frameworks and use the ensuing dialogue for good, healthy, progress, not just a staking out of territory and proclaiming oneself the victor.  

The result will be closer to the goals Sorkin mentions:  
"We need a lot of new cities and a lot of better old ones. They should assume many morphologies. We are very far from done with inventing the form of the city. Neither the reflexive reproduction of historic types … nor the ‘go with the flow’ of urban capital sluts will work it out alone"

Probably neither of those are LU or NU, but both have much to offer to conversation.

Environmental Urbanism

Excited to have a chance to head up to Seattle for tomorrow's lecture as part of the NOW Urbanism series at University of Washington.  Look for a report of the festivities in coming days.



November 18: 
Environmental Urbanism: Ecological Design for Healthy Cities
Kane Hall, Room 120 (University of Washington)

What does it mean to envision a healthy city - one that nurtures both people and the environment? Environmental Urbanism acknowledges and embraces the relationships between people and their material surroundings. This session will explicitly consider how the human processes of city making involve an ongoing negotiation with various non-human elements-- soils, water, atmosphere, and animals. By considering the intended and unintended effects of urbanization, our goal is to better understand how and to what extent we can intentionally shape future urban landscapes.


Lecture and discussion panelists include:

More on the Urbanism Wars

GSD as Epicenter

The escalation of voices in the (let's call it debate for lack of a better term) about some of the urbanisms out there - most notably New Urbanism and Landscape Urbanism, has kicked up a notch even in the past few weeks since the initial salvos. There has been a fair amount of dialogue around this (and also a lot of posturing), which from reactions I've heard has both engaged and alienated equal numbers from both camps.  As most folks have heard, in Metropolis, Duany attacked (there's no other word for it), the alleged 'takeover' of the Harvard GSD with a nefarious Waldheim-led transformation so that "the Urban Design Program will morph entirely toward third world initiatives—all offshore—thereby leaving the field clear for Landscape/Ecological Urbanism to be the GSD’s only urban program operating in North America and Europe." and that "there will not be much of whatever remained of the urbane, urban design sensibility. Landscape/Ecological Urbanism will rule without dissension."

The response from Alex Krieger (soon after) captured a less reactionary tone of a natural progression of ideology over time (something the CNU may consider a valuable lesson).  He mentions:

"I suspect Andres’ postulating a nefarious ‘coup’ at Harvard, in which Urban Design is erased in favor of something called Ecological Urbanism, is actually a cover for a personal worry that the term Landscape Urbanism will soon supplant New Urbanism amongst the purveyors of design sloganeering. The arrival of a new oracle, timely draped with environmental virtues is unsettling. "
Not really having a lot to say about the GSD or it's influence on the profession, I think the specifics of the exchange are less interesting than the very public 'shot across the bow' as Krieger put it, leading to what I think may prove to be a significant escalation on both sides of the battle lines (as if it were a war with only two sides...).  The war continues...

Some Recent Battles

Waldheim's post on Agrarian Urbanism got some convinced that Landscape Urbanism wished for a return to the 'sprawl utopia' of Wrights Broadacre City or other utopian agro-urban visions from the twentieth century.  Taking the mantle of oppositional dynamics of cities and ag lands - even when it is obvious there is a strong desire for some balance.  As Daniel Nairn, who came up with an interestingly balanced proposal of urban agriculture worthy of investgation, on his blog Discovering Urbanism mentioned, "A quick background check on Landscape Urbanism suggests that he may seriously be hoping to revive the Broadacre City. When we thought Jane Jacobs had thoroughly shellacked the whole decentralist train of thought back in the 1960s, a few academics have apparently determined that the dictates of avant garde subversiveness actually swing them back into the direction of auto-dependency and vigorous fragmentation of land."

He then swings widely to a broad generalization of the opposition, which i think is the most interesting point of the arguments, as it belies the balanced approach of land (ecological, productive, useful) within the urban pattern - which can be done without the sacrifice of density and urbanization.  More production in cities will impact urban form - it's inevitable and part of a conversation - but if we're really talking about where people live and what they want, it's very clear that food (for novelty, self-sufficiency, or even for apocalyptic preparation) is something than can and will be woven into our cities.  It won't look like Garden Block, and it won't look like Broadacre City...

This alludes to another in a line of misunderstandings, perpetuated by a cherry-picking of thoughts from literature - similar to that of Michael Mehaffy's article before, amping up the notions of justifying sprawl (how the hell the landscape urbanists caused sprawl is beyond me), or a desire for automobile-centric cities (being realistic about culture and conditions is not the same as condoning them).  I wonder what the critics would say about similar exercises like Weller's Boomtown 2050 which uses a number of utopian frameworks to envision development and density of Perth, Australia (reminiscent of the equally abstract 'Metacity/Datatown' explorations of MVRDV  These are not projects to pick apart - but are, at best, inspired and relevant thought exercises that we can learn from - with no notions that these are actual solutions.

The ideas that we understand an urban reality and 'get real' about sprawl, ecological systems, the prevalence of cars and transportation desires, amongst and other realities - is helpful, and (rather than ignoring them for some traditional ideal) reflects the sense of landscape urbanism ideology and venturing into history for precedents seems valid for any urbanist approach.  Also the common assumption that landscape or ecological urbanism is about throwing out the baby by displacing urban density and elimination of walkability, compactness, transit (good city planning, smart growth, new urbanism, whatever you want to call it) in lieu of protecting the bathwater and providing 'greenery', as demonstrated in Nairn's split shot of a natural lake scene and a downtown streetscape - is also equally misguided, as there isn't a call for suburban utopia of Broadacre or a modernist tower in the park of Le Corbusier.  An ecology of the city is not, like early 20th Century ecology, removed from humanity, but interwoven into it.  It is also not purely based, as critics would like to admit, on avant-garde artistic expression at the detriment to good urban principles.  It is rather not deterministic - relying on a fluidity and acknowledgement that we set a stage, but ultimately fail when we try to control all of the details of a city.


The point made by Waldheim, (and Daniel - it's Charles, not Peter) was not a tacit agreement with the proposed projects, nor a call to an agrarian suburbia dominated by cars.  Understanding the history of the agrarian urban tradition (my reaction to Waldheim's essay here) is vital - and discussion of historical examples is not to be equated with a blind acceptance of the merits of these proposals.  (Yes, hindsight is good, but vilification for revisiting history is something New Urbanists may want to avoid).  In fact, Waldheim seemed cautious of the proposals, not laudatory - a sort of a plea, in our rush to implement all things urban agriculture, to perhaps learn and not repeat some of history's mistakes.  As stated by Waldheim, it is an exploration, as:
"...these brief notes outline a history of urban form perceived through the spatial, ecological and infrastructural import of agricultural production. The choice of projects is based on the idea of agricultural production as a formative element of city structure, rather than as an adjunct, something to be inserted into already existing structures; thus this tentative counter-history seeks to construct a useful past from three projects organized explicitly around the role of agriculture in determining the economic, ecological and spatial order of the city."
Another post from Yuri Artibise gets into the discussions of the variety of available 'ubanisms' - mentioning the concept of 'sustainable urbanism' (also echoed in Duany's essay in the Ecological Urbanism book that is supposedly the 'first official guide of the new regime').  As mentioned: "Sustainable urbanism is an emerging discipline that combines creating multi-modal places, nurturing diverse economies and building high-performance infrastructure and buildings. It is more than a synonym for green or ecological urbanism. Rather, it looks at the triple bottom line by making sure that our urban centers are socially inclusion, economically dynamic and environmentally conscious."

This seems more like 'green' new urbanism than anything else.  And there's nothing inherently wrong with the sentiment - as an ecological lens to new urbanism has been much more integrated in recent years, which was a welcome addition.  It's the subtext that this is unique and different from other urbanisms (underlined passage to highlight this) that seems odd.  If one can reference above definition as antonymous to green or ecological urbanism, then it represents a common misunderstanding by many of green or ecological urbanism - reduced to greenery in cities with little to no regard for the actual social and economic functions of cities - which is a simplistic viewpoint that doesn't mesh with the literature.  More also to come on Duany's article in the EU book - which is pretty interesting reading...

Is it LU v. NU?

The responses above (and the current ire/debate/flame war) I believe stems from the very specific attack (there's no other word for that either) thrown out by Waldheim previously that LU was in diametric opposition to NU - as quoted:
"Landscape Urbanism was specifically meant to provide an intellectual and practical alternative to the hegemony of the New Urbanism.” 
And as Krieger mentions in response to Duany: "Well, those are fighting words, I guess, and so a counter-offensive campaign among the New Urbanists has been ordered. ". This kind of provocation is kind of asking for some reflexive response (perhaps that was the goal?) but I think muddies the waters in terms of the debate. While it's easy to say that it is placed in opposition, I don't see Landscape Urbanism being approached in any sort of systematic way to refute or offer an alternative approach directly framed as attacks on New Urbanism.  Perhaps a more nuanced reading and criticism of NU (along with some really good questions, like why West Coast Calthorpe NU seems so different than the Neo-Traditional approaches?)

There are too obvious fundamental differences and a philosophical gulf between the two concepts but its simplistic (and diminishes the value of LU) to frame it merely as an alternative to NU (see a recent, more broadly articulated vision from Waldheim here) - as it is looking at a vastly different context, scale, and approach.

Voices of Reason

A couple of readings from both sides of the argument give a much clearer ideological breakdown and are much less divisive - which I think is much more useful than name calling and stereotyping based on simplied notions of either NU or LU theory (both sides are guilty of reducing for the purposes of denigrating the other).  These two voices seem to offer a useful discussion of the merits.

The first, from Tim Stonor from The Power of the Network, questions the divisiveness of the debate, recognizing both positive and negative overlaps between the two and understanding the potential of these to reinforce each others.  From the post.
"The most striking aspect of the presentation was that Landscape Urbanism’s breakup of urban places into small enclaves is resonant of many projects of the New Urbanism, where relatively isolated “communities” of pretty, historically familiar houses are set within a green landscape. But, Waldheim was clear to present Landscape Urbanism as a critique of New Urbanism – as beyond New Urbanism. However, his critique focused on the aesthetic – the architectural treatment of the buildings within the pockets – rather than on the morphological – the pockets themselves. In terms of morphology and not aesthetics, the overlap between Landscape and New Urbanism outweigh the differences."
Stonor does go on to adopt the same 'grey versus green' assumption of NU critics of LU, stating that "The Landscape Urbanism projects that separate the green from the grey do not therefore do enough, if anything, to change the paradigm of “you can have either local or global but not both together” that the New Urbanism inherited from Buchanan." and goes on to use the New Urbanist 'transect' as a replicable model. "It should be to see the “grey” city, in itself, as an ecological object. To acknowledge that the grey city – as a network of streets and spaces that are simultaneously landscape corridors and conduits of human movement, community relations, commerce and ideas – is the green city. New Urbanism offers the concept of the “transect” as one means of doing so. This is a powerful start. One that Landscape Urbanism ought to be able to embrace."

The transect is an interest metaphorical model, again worthy of discussion (and I know for a fact that many LU folks are intrigued by the ideas - at least until it becomes a mechanism for Smart Codes).  It is not, however, to be translated into a one-size-fits-all solution (unless you can find me a great monocentric model city where the categories work).  Much like economic city models that use monocentric principles (simplified versions of city dynamics), they are fine for analysis, but not necessarily for action because they don't capture the complexity of the reality of cities - because no code is that smart.  

I also wonder, somewhat, where these 'projects' are that are the basis of some of this criticism (as I've mentioned previously, this is still a very vague notion - and I would love some specifics, if only to evaluate what is being evaluated). I don't think there's agreement on what is a work of landscape urbanism (if it exists at all), so using project specific criticism seems a bit hollow.  Is it site based?  Aggregations?  Districts? or just viable at a city scale... I'm slowly amassing some ideas from readers, and it's leaving me with more questions than answers - so LU proponents and NU critics - let's look for a shared understanding that at least is a point of departure for philosophical differences we can debate.

:: Crossroads Project from LA Dallman

Another post, (and belying my ideological stance) is what I think is the most elegant and eloquent response I've heard (worth all of us reading) from Charles Birnbaum, written in The Huffington Post today.  voice of rationality to the entire proceedings.  The sentiment from the article, which is gleaned from a number of practitioners and academics can be summed up as such:
"Since the early 1980s, Waldheim noted, landscape architects have played the role of environmental advocates, concluding, "the advocate scenario reached the limit." He added, "The rise of landscape as a design medium is bigger than all of us and none of us have exclusive access." Waldheim is building a big tent in theory and now in faculty. The approach welcomes shared values, myriad and overlapping expertise and a celebratory embracing of complex social, environmental and cultural systems. He notes, "there is a decentralization to horizontality and it is very difficult to structure urbanism out of buildings. ... 
I am among those that believe that the time for landscape architecture has come and that there is sufficient evidence of increasingly greater global demand for our leadership. Our potential role has never been more central. So to Duany and those that disagree or feel threatened, go back and read Olmsted, Jr., because in addition to the principles that you have liberally borrowed for context-sensitive architecture and planning, much can be gleaned from Olmsted Jr.'s enormous comfort zone, which like the Landscape Urbanism movement, embraces a shared value, systems-based approach that is built on collaboration and open mindedness."

Birnbaum reaches to Waldheim, Czerniak, Pollack, and even Martha Schwartz for some of the recent thinking on the emergence of landscape architecture, who collectively provide a range of ideas in practice and academia.   Perhaps for those not excited about Martha Schwartz as our defender, can look to folks like Mark Rios (both and architect and landscape architect) who offers a great perspective:  
"Architects are trained to design objects. They go through design school looking at form and program. Landscape architects look at voids, space, systems, based in training in ecology. They deal with bringing spaces together -- how they are transformed through ecology. It feels to me that the basic training of the professions is different and landscape architects deal with city building in holistic ways."  "New urbanism does not do that. It is a holistically fabricated place that does not look at pieces in the puzzle." He suggests, "We need to find ways to be fabric weavers -- you can't have a whole city of objects."
The 'we' in this case is all of use collectively, and divisiveness only furthers the gulf, to the deteriment of our collective impact on cities.  Only with an understanding of each side can we compare and contrast - so those with issues with New Urbanism (or parts of it) need to learn what the concepts and results are.  Those who aim to dismiss Landscape and Ecological Urbanism may do everyone a favor and do the same.  It's a simple case of knowing thy enemy. 

Getting Back to Urbanism

This is illustrated in another recent definition (from Tom Turner at Gardenvisit) for the slippery idea of what landscape urbanism (or at least the urbanism part) actually is.  From some recent discussion, he states that: "LANDSCAPE URBANISM is an approach to urban design in which the elements of cities (water, landform, vegetation, vertical structures and horizontal structures) are composed (visually, functionally and technically) with regard to human use and the landscape context."  I'd disagree, saying the reference to 'design' and composition make it landscape architecture, not urbanism.  A good case in point is the High Line - which can be understood in terms of landscape urbanism through its contextual place in the urban fabric, but in application is seen as a design using compositional principles.  See why this is so confusing?

Thus, I find it funny that the term 'urbanism' (at least how I interpret it) has become disconnected from the origins that makes it a powerful analytical and theoretical tool.  Urbanism, per se, is not a planning system or urban design method, and it is definitely not a landscape design strategy or architectural approach.  Rather, it is a way of reading cities in ways that yield information that is utilized towards those ends (which not being the means to those ends).  As Wikipedia simplifies it: "Broadly, urbanism is a focus on cities and urban areas, their geography, economies, politics, social characteristics, as well as the effects on, and caused by, the built environment."


One aspect I think worthy of discussing is the general premise that New Urbanism is a codified normative planning strategy, meaning 'that it is indicative of an ideal standard or model', while Landscape Urbanism, which is primarily a postive (or descriptive) planning strategy, aimed at describing 'how things are'. This is overly simplified, but really constructive when you consider that landscape urbanism is looking at a different worldview that is much closer aligned to what we mean by urbanism - not seeking out or determining outcomes that is more akin to architecture, landscape architecture, and urban design.

I've even heard folks in the urban design realm (and landscape architects as well) starting to get their hackles up, criticizing LU by either saying it's irrelevant or that it is what we're already doing.  This misses the point, as you are fundamentally talking about a key different between design and urbanism - which seems lost on most folks.  Thus I can be an urbanist (landscape, ecological, or other...) while also being a landscape architect - not having to trade one in for the other because they are fundamentally different modes of operating in cities.

Comparing Apples to Apple Trees

The analogy that comes to mind, instead of saying these are comparing apples to oranges, is that the comparison is closer to comparing apples (NU) to apple trees (LU).  One is a discreet product, the other a complex system.  One is small and decipherable, the other larger and more complex.  One yields understandable forms, flavors, colors and textures, while the other is more varied (not containing an inherent 'taste' or 'style') but forming an armature for myriad possible differences in its fruit.   Yet they both coexist and are reliant on each other... much as the apple and apple tree are.

I think perhaps to take the metaphor a bit further let's call a city an apple tree, and the Landscape Urbanism a larger-scale, complex, rooted, system and each individual apple is a context-based product yielding a specific result.  Cities, through urbanism, have a generalized structural focus on the 'how things are', while sites have a specific programmatic and spatial configuration determined through urban design, planning, landscape architecture, and architecture.  I believe this is why it is so difficult to pin down 'works' of landscape urbanism - because the concept doesn't operate at the scale of works, but rather at a larger scale (what that is is undetermined), one concurrent with a true definition of urbanism. 

The Future of Urbanism


Perhaps as mentioned by Mason White on Twitter, is there an opportunity to open up the debate on urbanism to a wider array, and see who is the survival of the fittest: He posits:  "this new urbanism vs landscape urbanism scuffle could use more ____ urbanisms to let a full fledged Darwinian onslaught unfold. any takers?"  The [blank] urbanism debate not withstanding (and frankly I'm enjoying a sort of cage match format) - the whole concept of urbanism as a term is quickly becoming somewhat comical (similar to the modification of terming ending with -urbia that preceded it) with either serious or seriously funny iterations - which if anything is going to render meaningless the concept of which we try to understand.  Few of these discussions are about 'urbanism' in a true sense, but rather descriptors for planning, urban design, landscape architecture and architectural solutions.  I wonder what should, and what is going to replace it, because after this we may have to abandon it's lifeless corpse, leaving it again to those who want study cities, not design them.

I do agree that, once all the huffing, puffing and chest thumping is over, there will eventually be a shaking out of a somewhat cohesive (and constantly evolving) group of approaches to urbanism.  Not one of these will be the answer to all of our problems, but perhaps we can reach a level of stasis where each is mutually reinforcing and complementary to the others to allow a range of potential readings of the city.  These 'urbanisms' will be reinforced by a range of strategies for portions of the urban areas, through planning, urban design, site design, and architecture.  Any designer/urbanist/planner/architect - lending to the flaws of a single-purpose approach that we've seen so shallow and misguided throughout history - is going to be quickly left in the dust of the more enlightened and holistic thinkers.
