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.

:: Datatown from MVRDV 

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?)

:: Calthorpe's Urban Network - image via Neo-Houston

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?

:: High Line (landscape design or urbanism) - image via Arch Daily

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.  

:: Transect - image via Think of Thwim

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.  

:: Apple Trees on the Chantemesle Hill - (Monet 1878) - images via monetalia

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.

Artificial Rivers

A post on Gardenvisit discusses the historical idea of creating artificial landscapes, in this case the Serpentine Lake in Hyde Park, to appear 'natural'.

:: image via Gardenvisit
"In 1730 Queen Charlotte ordered the damming of the Westbourne River as part of a general redevelopment of Hyde Park and Kennsington Gardens by Charles Bridgeman. The Serpentine Lake in Hyde Park is the remnant of the Westbourne River which since 1850 has been diverted into a culvert and runs into the Thames near Chelsea. “The Serpentine Lake was one of the earliest artificial lakes designed to appear natural” and was widely imitated. The Long Water because of its relatively undisturbed nature is a significant wildlife habitat."
The current imagery shows the modern configuration, which is interesting as it has maintained a similar configuration through time, but also doesn't have the undulating crenelations of a more 'organic' river that would probably pass for naturalism in modern form. 

:: image via Google Earth

Some images of the site as is currently configured, which is both integrated into it's urban context but also maintaining a natural appearance.



 :: images via Wikipedia

While there are probably hundreds of examples similar to this, and the fact that the site is mostly contained with a park (with a purely formal goal, versus ecological) - keeps it some distance from an engagement in the urban form and a viable idea of landscape or ecological urbanism.

It did remind me of what I think is a very good example of 19th Century work/precedent of landscape urbanism, Olmsted's restoration and naturalization of Boston's Back Bay Fens - a landscape that, as part of the Emerald Necklace, as a historically engineered construct, is today considered a natural and ecologically functioning natural area that the City was built around.  In fact the inverse is true, as the space was massively designed and engineered, with the subsequent urban areas building up around the space.  As seen from the pattern of Olmsted's plan in 1887, the Back Bay fens is a naturalistic work of landscape architecture, but also a feat of engineering that mitigated flooding in the area.

:: image via Wikipedia

And the current urban pattern, showing the infilling of urban areas around the 'open space' in the subsequent 130 years (yet remaining remarkably intact).  Building up of the urban density around this 'constructed landscape' is striking, especially in contrast to the bucolic beginnings.

And some additional information and text from an MIT architecture class site 'The Site Through Time' - showing the historical evolution of the park - emerging from the marshy landfill that constituted the majority of the Boston area (see more on the urban expansion through landfilling here).


:: images via MIT

While it is easy to consider this an 'extension of nature' it is clear this is a constructed urban landscape, and that after time it is hard to see this historical ecology without some digging - as it is perceived as nature.  A great site as part of the David Rumsey collection overlays a number of historical maps (there should be one of these for every city), which show the Back Bay area in different configurations (but the same scale and view) prior to and after 1887, which show the marsh, early landfill, evolution, and eventual implementation of the Olmsted plan (years 1856, 1874, and 1897)




:: images from David Rumsey

More on this one soon (in particular proto-landscape urbanism qualities of this historical work in providing a landscape framework for urbanism).  It is telling that most people consider this 'nature', similarly to the very constructed Central Park and other naturalistic parks of the 19th Century.  It is more specifically artificial ecologies as urban infrastructure - a novel concept well over a century removed.

:: Back Bay Fens - 1892 - image via The Olmsted Legacy

I've used this example before, in an article from a few years back (Winter 2006) called 'Creating Nature' (links to a PDF published in the ASLA Oregon journal ORegonland - article starts on pg. 4).  For anyone interested in more detail, check out one of the essays in William Cronon's sporadicallyengaging 'Uncommon Ground: Rethinking the Human Place in Nature', specifically Anne Whiston Spirn's great essay 'Constructing Nature' which mentions this project and others by Olmsted using similar naturalistic tendencies. But for it's picturesque aesthetics of a century ago, it sounds a lot like landscape (or ecological) urbanism to me:
"Boston's Fens and Riverway were built over nearly two decades, (1880s - 1890s) as an urban 'wilderness,' the first attempt anywhere, so far as I know, to construct a wetland.  These projects, built on the site of tidal flats and floodplains fouled by sewage and industrial effluent, were designed to purify water and protect adjacent land from flooding.  They also incorporated an interceptor sewer, a parkway, and Boston's first streetcar line; together, they formed a landscape system designed to accommodate the movement of people, the flow of water, and the removal of wastes.  This skeleton of park, road, sewer, and public transit structured the growing city and its suburbs."  (Spirn quoted in Cronon, 1996, p.104)

On Agrarian Urbanism

An opportunity for point-counterpoint on the topic of Agrarian Urbanism - one that, with the recent explosion of discussion and interest in urban agriculture - is vital to discussing the place of food in the city, and what impact this will have on the form and function of our urban agglomerations.  The topic is poignant here in Portland, as it is both a hotbed of urban agriculture, as well striving for density through urban growth boundaries (UGBs) to protect adjacent farmland.  The question becomes one of spatial configuration - as space within cities can be allocated in whatever configuration we choose - but this does have implications on the overall spread.  I'm amazed with the ability to drive 10 minutes and find working farms - (while also looking around my neighborhood and finding working produce, poultry and other small-scale productive urban gardens).  Both of these will contribute to a final spatial arrangement of the city.

:: image via OregonLive

More on this urban/rural - inside/outside dichotomy, but for now a few bits of related reading.  Charles Waldheim has a recent post on Design Observer: Places, 'Notes Toward a History of Agrarian Urbanism', which is excerpted from the recent issue of Bracket: On Farming' and takes a mentioning Wright's Broadacre City, Ludwig Hilberseimers 'New Regional Pattern' and Branzi's Agronica  (a great article, once you translate from Italian here) which is great as a social critique, if not in its formal design qualities.  Looking backwards to see the future, the idea is to think about these not in terms of individual interventions, but with an eye on holistic urbanism.  From the article.
"To date the enthusiasm for slow and local food has been based, on the one hand, on the assumption that abandoned or underused brownfield sites could be remediated for their productive potential; and on the other it has been based on the trend toward conserving greenfield sites on city peripheries — on dedicating valuable ecological zones to food production and to limiting suburban sprawl. But these laudable goals are not much concerned with how urban farming might affect urban form."
:: image via Places

As a historical overview, Waldheim's thesis (the point) is to understand some of this utopian precedents, 
Broadacre City as a vision is appalling, but as a futurist prediction of auto-dominated sprawl, it may not be that far off.  To augment the examples mentioned, I would add Le Corbusiers' Radiant City - perhaps with a less modernist blank green space but as dense spires amidst farmland... Both this and Broadacre City are equally dispiriting, but in polar opposite ways.  In the abstract - both could be vehicles for agricultural urbanism that will appeal to a particular urban/suburban demographic of the population.

:: image via Brian's Culture Blog

The Howard-esque Garden City/Greenbelt City  is another integrated agro-urban example, focused more on concentration of uses (focused urban density) than full integration.  Similar to the drivers of Portland's UGB, there is clear compartmentalization of agriculture from city - keeping it in proximity but also at arms length... to connect the urban dweller to the rural worker in physical and cultural ways - at least in the abstract.

 :: image via Cornell Library

All the examples are not urban per se (as in densely agglomerated), but rather suburban (dependent on continued decentralization) in their contexts (or at least in their location of agricultural uses) - but do tell us much about the cooperative potential of the urban and the agricultural... perhaps the connection between the desire for land and space (our roots) and the historical suburban dispersion.  It was less about a 19th century model of  fleeing the ills of the city, as it was about recapturing some of our agrarian ideals.  The problem therein, lies in really tackling this in a truly urban form not the quasi-middle ground of suburbia (although a ripe ground for re-purposing to include agricultural uses, for sure). 

:: image via Places

The point is that it is fundamentally about what we want in cities (the actual urban parts, not the sprawling metropolitan statistical areas) - monocentric agglomeration and density or polycentric dispersion and space?  The point being, when looking at the 'landscape' of cities - the spaces for non-building, road, etc. there is opportunity (Mason White's 'Productive Surface'?) available at a variety of scales, where 'agriculture' amongst other uses (programmed and other) can exist within cities.  This may be the simplistic, Thus the continuum of spaces is not specifically relegated to the dispersed - large tracts of agricultural land in cities (reducing density, likely leading to sprawl) or the hyper-dense (and I say neo-utopian) vertical farms (technological solutions at exorbitant cost - although I hear they may save the world).

:: image via Treehugger

It's obvious that industrial agriculture is undergoing a necessary shift, and that some space is necessary for food production in the city, but the extent and shape of this (both spatially and culturally) is yet to be determined.  This differs (and influences) urbanism in many ways, depending on what you believe, where you live, and what you grow - amongst myriad other variable.  But is on the minds of many.  These are leading to both inventive proposals, the provocative, the cute and ephemeral, the strange, or the already tried and true - yet somehow new ideas, in the name of agriculture made urban.

The historical account of Waldheim may be compared to (the counterpoint), a similar crop of recent writings by Andres Duany on the same topic, particularly the New Urbanist recent interest in Agricultural Urbanism - which spawned a very NU-centric book (but mostly referenced by Duany as the same 'Agrarian' moniker).   As mentioned on Planetizen, this is to become an emphasis:

"At the 18th Annual Congress for New Urbanists, Andres Duany announced 'Agrarian Urbanism' as his new planning emphasis. He believes that the success of New Urbanism has stultified its progress and reduced its potential...  Agrarian urbanism is a society involved with the growing of food," explains Duany. He now aims to create a locavorous community where the resident is responsible for designing his "own utopia." Greg Lindsay believes the ideas could be attractive to the Whole Foods demographic but is unsure if they are ready for the hard work involved with growing food. Duany concedes that his agrarian communities would still "end up hiring Hispanic laborers to do the dirty work," but that these laborers would have a closer relationship with their employers."
For some of Duany's view on this topic (echoing the above quote) you can turn to Fast Company,  New Urbanism for the Apocalypse, a snapshot of the CNU annoucement, particularly how this viewpoint fits into the NU paradigm.  From the article:
"Agrarian urbanism, he explained, is different from both "urban agriculture" ("cities that are retrofitted to grow food") and "agricultural urbanism" ("when an intentional community is built that is associated with a farm)." He was thinking bigger: "Agrarian urbanism is a society involved with the growing of food." America abounds with intentional communities, he pointed out -- golf course communities, equestrian ones, even the fly-in kind. So why not build one for locavores? And they can have as much land as they like -- it's just that they would have gardens instead of yards, or community gardens and window boxes if they choose to live in an apartment. Their commitment to "hand-tended agriculture" would be part of their legally binding agreement with the homeowners' association. "You design your own utopia," he said. Instead of a strip mall in the town square, there's a "market square" comprised of green markets, restaurants, cooking schools, an agricultural university, and so on. "This thing pushes buttons like mad," he said. "The excitement this triggers -- they get as excited about this as they did in the old days about the porch and the walkable community."

I particularly enjoy the idea of writing this into the CC+R's of a community (above underlined passage) a sort of 'thou shall farm' edict that allows you to design your own utopia, as long as it fits within certain cultural and community expectations as defined and dictated those in power.  Is this the small-scale version of hobby-farming to the suburban masses - because it isn't really a model of truly 'urban' development?


Another, from Houston Tomorrow, sums up a recent presentation on 'Agricultural Urbanism: Transects & Food Production' with a focus on the recent NU-inspired Southlands project in BC .  Picking up the thread of CNU18, Kunstler shows he may be on board, quoted  on Clusterfuck Nation echoing the need for this return to the farm as also a response to impeding climate change related disruption. (underlined quote mine)
"Among other things, the most forward-looking leaders in the New Urbanist movement now recognize that we have to reorganize the landscape for local food production, because industrial agriculture will be one of the prime victims of our oil predicament. The successful places in the future will be places that have a meaningful relationship with growing food close to home. The crisis in agriculture is looming right now -- with world grain reserves at their lowest level ever recorded in modern times -- and when it really does hit, the harvestmen of famine and death will be in the front ranks of it."
The Houston article links to the long presentation by Duany about the topic, via YouTube - although I haven't had a spare two hours to check it out yet... anyone will to summarize, let me know.


For some related content, one must delve into the interesting concept of CPULs.  Also check out the project 'Garden Block' project by Daniel Nairn, which has garnered praise for it's plausibility from Smart Growth advocates like Kaid Benfield ('Agricultural Urbanism that actually is urban') who have been critical of some urban agriculture proposals.  As an object of defined spatial arrangement incorporating density and agriculture - it seems to work for this block (one that would attract some, but not all urban agrarians).  I expect and desire more models, both the practical to the sublime, from NU/LU/EU and other 'U's - investigating codified solutions and abstract indeterministic ones - giving plenty of fodder for discussion on the future of food in the city.

The question of this not just as a site or district image, but as it relates to the overall structure of how we plan and shape cities - is a much larger question indeed.  Looking at utopian precedents, and site specific examples, we have opportunities for not just the physical integration of agriculture into cities, but a clear picture, good and bad, of what some of the consequences may be.

New York City's Amphibious Heritage

Via the always interesting Strange Maps, a utopian proposal from the early 20th Century for New York City with current parallels of either the practical Dutch examples of land reclamation or the ridiculous Dubai examples of artificial islands.  Immediately making me think of Robert Grosvenor proposal for 'Floating Manhattan' - This 1911 proposal by Dr. T. Kennard Thompson entitled 'A Really Greater New York' poses a large scale land reclamation of New York and the surrounding areas - adding 50 square miles of land to the metropolitan area.

Some additional explanation:
"...proposed to expand New York into its adjacent waters for a grand total of 50 square miles. Thomson was neither a lightweight nor a crackpot. As a consulting engineer and urban planner for the City of New York, he had been involved in the construction of numerous bridges and over 20 of New York's early skyscrapers, specialising in their foundations, designing pneumatic caissons. It was the versatility of these caissons that would lead Dr Thomson to envisage a much wider application for them. In August of 1916, he wrote an article in Popular Science, advocating 'A Really Greater New York'."
For a full picture of the concept, check out the full post, but in a nutshell, my favorite part was the new proboscis attached to the end of Manhattan ('New Manhattan') - retaining a New York/New Jersey split.  Think of the cost-benefit of this (ecosystem health and environmental impact aside) were it built 100 years ago.

This isn't to say that Manhattan, and many other cities around the world haven't expanded their footprint in less dramatic ways through landfilling, edging slowly into the adjacent lands.  Is it such a crazy proposition, thinking of the value of land in Manhattan and other densely developed (and land-locked) cities, is it such as strange idea?  Boston is a great example of a city built on fill, not by spreading inland,  but by capturing significant amounts of land within the Charles River basin and Harbor areas.

Or instead of giving this over to building, how about restoration of the areas where we've destroyed the margins through industrialization.  We could add, through land-filling, wide vegetated buffers for open space and restoration of coastal ecosystems engineered specifically for recreation, habitat, and riparian health - strips for phytoremediation between city and river - buffers for us and to remedy or ills.  While difficult to generate using existing built up edge conditions, this new process of reclamation of riparian corridors, although artificial (a la P-REX), would be a hybrid ecology that may work versus a traditional, reactive, natural methodology.

Landscape Performance Series

Interesting link to the Landscape Architecture Foundation's new resource - the Landscape Performance Series - which is sort of an adjust to the Sustainable Sites Initiative which is "...designed to fill a critical gap in the marketplace and make the concept of “Landscape Performance” and its contribution to sustainability as well known as “Building Performance” is today. The LPS is not a rating system, but rather a hub that brings together information and innovations from research, professional practice and student work in the form of case study briefs, benefits toolkit, factoid library, and scholarly works.


As someone who is adamant that our profession attain a much higher level of rigor in determining the efficacy of designs, this is a great new addition.  The projects are interesting, cover a wide range of landscape typologies, and offer data that is not available in typical media 'puff-pieces' or even more technical papers.  A typical case study includes a number of interesting features.  For instance, a look at the great Seattle project, the Thornton Creek Water Quality Channel, provides an overview, sustainable features, challenges/solutions, cost comparisons, lessons learned, and project team.

While the data is more expansive, we still have a long way to get really good information that can not just validate projects but can also drive future design solutions.  Information on cost, performance, and technical data is still anecdotal - not saying it doesn't exist, but that it either hasn't been studied, or hasn't been released.  The issue with data and research is always not the results, but the methodology and transferability to future projects.  Every landscape architect should study the Case Study Method for an approach to post-occupancy evaluation, particularly Mark Francis' article in Landscape Journal, that should become the foundation of every project - not just those with innovative features or with funding to provide necessary data.

From a design perspective, we need greater access to available research.  I've had an interesting (and wonderful) opportunity to have access to the research library resources of a major university, and it has been amazing to see all of the data out there that has not trickled down to the design community in a meaningful way - even when you are actively searching for this information.  Take for instance the state of research in Green Roof technology, which in common access is limited to minimal, local, or specialized data on soils, plants, and benefits.

A very quick survey of some recent literature yielded international data on building heat flux, growing media for stormwater retention, water quality and building insulation, energy performance, plant establishment, habitat function, cost/benefit through life-cycle assessment, economic value, innovative structural techniques and systems, and heat island mitigation.  In addition, there are technical studies that offer innovative modelling techniques that provide macro-scale, not just site specific data, about the benefits of sustainable strategies, including green roofing.

Aside from anecdotal, feel good stories about ephemeral or vague benefits, these offer tangible examples of research that can lead to better design and implementation.  While all of these research studies are not immediately transferable, many are, and it highlights the need for designers, even those not doing research, to be more involved in the creation of research agendas that will actually lead to better solutions.  It's not an either/or scenario - but one where we much work together if we are to make our landscapes more viable, but also give ourselves the tools to measure and evaluate them.  I commend the LAF for their work - and encourage others in the landscape architecture community to support and expand this work.

Feral Green Streets

On E. Burnside Street in Portland, the construction of the Burnside-Couch Couplet, a project aimed at 'humanizing' the wide arterial that slices through Portland and provides the dividing line between North and South. Construction is ongoing, and as part of the design, the streets on both sides of the couplet have a number of green street planters. As I was moving into my new office, I couldn't help but notice a new 'planting' scheme on the Burnside planters - predominately populated with a mixture of weedy pioneering vegetation.



The jute netting and wood (??) weirs have been in for some time - prepped for planting and keeping erosion at bay. The late summer of sun and moisture have allowed for perfect conditions for weeds to germinate in pockets of wet ground, making for a lush green tapestry that is starting to overtake many of the curb extensions - most probably from weeds carried from car tires and deposited in the planters.





It would be interested to see if the general public noticed the difference between these 'feral' varieties compared to many of the specifically planted varieties (which at times look somewhat messy themselves) - or more likely what do business owners think? Will the weeds persist after planting? Will hand removal be adequate to keep these down once the planting is completed? How much money could we save with treatment of stormwater facilities as early successional ecosystems recently impacted with disturbance? Would this vegetation work better or worst than the monocultural rushes that have seemed to become the mainstay of storm facilities? I'm kind of hoping they just leave them as some form of radical urban ecosystem experiment - followed by soil only ecoroofs that are left to colonize via birds and wind.



Not sure what the delay in planting actually is - as the heat of summer is over and we've now hit a good part of the season for planting sans irrigation. Another month and these will be bursting and lush with weedy varieties. Some of the newer ones have yet to be overtaken, as seen in a view of one of the pristine sections - ready for colonization.

Sodding Bridges

Although I did get stuck waiting for one of the many bridges today, my title for this post is more tongue in cheek than brit-inspired rage. Bridges are part of the fabric of Portland, and give our city much of it's identity while also serving as vital infrastructure connecting east to west (and north to south). While we currently are in the midst of a contentious debate about a future major bridge redo, it is perhaps fitting for us to recognize the essence of bridges, and their importance to our identity, as we debate what will be an expensive and long-lasting symbol of who we are. For these reasons, we endure the occasional bridge lift - and relish in the industrial beauty of our riverine skyline - in this case the 100 year old Hawthorne bridge.

The plans to cover the bridge as part of the Portland Bridge Festival a two-week celebration of our bridges. Of particular interest is the 'Brunch on the Bridge' which included covering the interior lanes with sod and opening the bridge up for a park for the day - to picnic and relax in this temporary linear open space.

I missed the opportunity to make it down to check it out - but a shot to give you a gist - prior to the sod going away for a range of permanent installations around town.
