Waterscape Urbanism

I was struck by a recent mis-use of the term landscape urbanism in this article from the Atlanta Journal Constitution on the need for climate change inspired floating homes.  Quoting  Thai landscape architect Danai Thaitakoo on the need for dealing with innundation.

"Climate change will require a radical shift within design practice from the solid-state view of landscape urbanism to the more dynamic, liquid-state view of waterscape urbanism," says Danai, who is involved in several projects based on this principle. "Instead of embodying permanence, solidity and longevity, liquid perception will emphasize change, adaptation."

While amphibious architecture is nothing new, and i agree that it will become more common in the future there are two points.  The first is minor - that of the mis-characterization of landscape urbanism as 'solid-state' and 'embodying permanence, solidity and longevity'.  If there's any flavor of urbanism that emphasizes change and adaptation, it's landscape urbanism - so i think there's a disconnect in that above paragraph.  Just saying.

Second, and more troubling, is the idea that we must react to climate change by building floating structures - rather than address the topic at hand.  It's similar in nature to dealing with semi-urban forest fires by designating fire-safety clearing zones of tinder and brush around houses, rather than looking at not building homes in these areas - or heaven forbid - letting them burn.  Or coming up with vertical farms due to our misguided agricultural subsidies and policies that make it impossible to grow a variety of food on terra firm.   

Its cause.  Not effect.  We spend way too much time on solutions to problems and calling it need-inspired innovation - rather than getting to the real root of the problems themselves.  May not be as press-worthy of sexy, but at least its real.

Anne Whiston Spirn Lecture in Portland

An upcoming lecture by Anne Whiston Spirn entitled Restoring an Urban Watershed: Ecology, Equity, and Design will be happening on Monday, January 23rd, from Noon to 1pm at the Portland Building, 1120 SW Fifth Avenue - Second Floor, Room C.  The brownbag is free and open to all.  Here's a synopsis.

The West Philadelphia Landscape Project is a landmark of urban design, watershed management, environmental and design education, and community engagement. Anne Whiston Spirn, who has directed the project for 25 years, will describe the story of the restoration of the Mill Creek watershed as a model for how to unite ecology, design, and community engagement to address social and environmental problems in low-income communities. Anne will also discuss her book, Daring to Look: Dorothea Lange's Photographs and Reports from the Field.

Introducing THINK.urban

I am happy to announce the formation of a new organization, THINK.urban in Portland, Oregon.  Along with colleagues Katrina Johnston and Allison Duncan, our group plans to promote, as our tagline mentions: "Better Design Through Applied Research."   We bring a range of experience in urban design research, landscape architecture, urban ecology, public space, and social science, combining academic rigor with creative expression.

In short, we are a research based non-profit that connects academic research to urban design practice through a number of means, including expertise, scholarship, interventions, publications, and consultation with professionals.   We have current focus areas in public space, streets, and landscape - and cast a broad net across urbanism in general - with a goal to act as a bridge between theory and practice.  We are currently forming the 501(c)(3) organization and recruiting board members, so more is happening in 2012.

A snapshot of a couple of the projects that we are working on in tandem and as an extension of our studies at Portland State, include:

• Public Space + Protest:  OPDX  (Katrina Johnston)
• South Auditorium Study (Allison Duncan)
• Hidden Hydrology Project (Jason King)

Find out more about the activities of the non-profit on the website and ongoing blog, by following us on Twitter @think_urban or by checking our our new Facebook page.  

In the spirit of economy (and my own sanity), I will be cross posting periodically between these two sites - particularly posts that are relevant to both - but will still have original content on each as it makes sense.   Enjoy!

RBC: Notes on the Third Ecology | Kwinter

Notes on the Third Ecology | Sanford Kwinter

Kwinter used the dichotomy of city/nature, rooting in our historic perceptions that evolved in the Industrial era.  As mentioned, this concept is characterized by a time "...when immense upheavals in social, economic, and political life transformed the very landscape around us and our relationship to it irreversibly and in depth.” (94)

In essence, the evolution of cities had previously existed in tandem with available natural resources, which limited their size and scope. Technological improvements in transportation and the accumulation of wealth shifted us from local dependence on surrounding nature.  This has continued in our technologically advanced modern society, as Kwinter explains:

“Three billion of earth’s citizens today live in cities, and virtually all of the exponential growth in population anticipated over the next fifty years will be urban. A significant number of those who do not live in physical urban environments increasingly live in psychic ones...” (98)

This concept of modernization leads us to the desire to 'clean up' areas that don't fit a specific conceptual idea of use or style.  This originally persisted in slum clearance which replaced the squalid with placelessness, trading one dysfunctional environment for another.  We continue this idea of 'modernization' in many cities today, as Kwinter points to, such as Beijing’s Hutongs or the focus of the remainder of the essay: Dharavi slum quarter in Mumbai, where he mentions that “Current ameliorative development in cities targets the archaic physical structures and the archaic social lifeforms that adhere to them.” –  (99)

The concept of 'modernization' and 'fixing' problems in this case is based on a different set of cultural expectations that those held by the people of slums like Dharavi  which are driven by the "...intensity of its local commerce, the vastness and ubiquity of its social markets, which are virtually coextensive with its metropolitan fabrics.” (99)  This includes economies that exist on the detritus of modernity, such as the secondary economy of recycling of materials.

These economies have existed (persisted) for centuries, "part of an ancient ecological and urban web." (100) which allows these areas to function.  It is suprising to hear that Dharavi creates it own sort of socio-ecological structure that is self-supporting but also supports the larger metropolis of Mumbai in which it is located.  Again Kwinter explains:

“Though it may be the world’s largest slum, it has 100 percent employment. But Dharavi is also a city in itself, and its streets and alleys know no distinction between work and social space or even domestic or residential functions… Although sanitation, water, and sewerage represent acutely serious problems in Dharavi, it nonetheless represents the veritable lungs, liver, and kidneys of greater Mumbai, as it cleans, reprocesses, removes, and transforms materials – and adds value – that are endemic to the economic and material functioning of greater Mumbai and beyond.” (101)

While rife with issues of poverty and social inequality, this 'community' has an identity, "a place of visible and palpable civic pride…” (102) and function that will be permanently destroy by processes to 'fix' and 'modernize' it, through clearance and rebuilding.

::

Kwinter elaborates on this point of the double-edged sword of slum clearance::

“Although such urban transformations are always done in the name of remediation and modernization and presented as a way to transfer prosperity to ever greater numbers of inhabitants, it is clear that the effects in this case will not only be cultural and political but will have profound ecological impacts, both existentially and in terms of the efficient means – currently at risk of being lost – by which raw materials have traditionally cycled over and over through the system.” (102)

Instead of clearance per se, but a true accounting of the human ecology and perhaps the ability to learn from and expand our worldview by studying these cities and their ad hoc principles of slum urbanism.  Kwinter quotes Thomas Friedman in this context, mentioning that “We may well learn over the next years that cities, even megacities, actually represent dramatically efficient ecological solutions, but this fact alone does not make them sustainable, especially if the forces of social invention remain trapped in tyrannies that only ecological thinking on an ecumenical scale can free us from.” (103)

Thus the imposed order of what constitutes the appropriate ecological city is in need of re-evalution.  Kwinter evokes Guattari’s ‘existential ecologies’ a “concept intended to compromise everything that is required for the creative and dynamic inhabitation and utilization of the contemporary environment.” (104) as a frame for reconciling this condition, and folding the social and natural together into a coherent, non-dichotomous idea of city & nature. As explained:

"...the cultural and social dimensions of our environment as rooted in the natural - are poorly theorized and understood, and at any rate insufficiently acknowledged.  Yet they are the key components of our ecology, without which none of the other parts could fit." (104)

The importance of studying these areas is evident, as “we are still unable to imagine most of the changes required of us, nor even to imagine the scale of required change as possible… it does pose an unprecedented challenge to the design community to serve as an organizing center for the variety of disciplines and systems of knowledge whose integration is a precondition for connecting them to clear political and imaginative and, most important, formal ends.” (105)  The precedents of Dharavi and restraint in creating order out of their inherent chaos is a challenge to our mindset as planners and designers, but the new complexities of our contemporary urban condition demand a level of acceptance and understanding never before realized.

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:

The Red Brick Chronicles - 'Advancement verus Apocalypse' by Rem Koolhaas

As I mentioned in the recent reckoning of the L+U blog, I wanted to focus on a number of recent texts that I've had the chance to delve into (by disconnecting myself from the nefarious teat of the RSS feeder)  Of significance is finally getting around to expanding on the initial readings of the book Ecological Urbanism (check out Intro by Mohsen Mostafavi, 'Why Ecological Urbanism?  Why Now?, in two parts here and here) which although gigantic, dense and brick-like, is also yielding some engaging content.


Thus in lieu of another option for a book with over 100+ essays and snippets from various authors, I'm going to chronologically post on each one on a mostly, time permitting, daily basis - in some cases just a fragment or two worthy of discussion - sometimes in more length.  Hope you enjoy.  Here's the first installment - follow by regular installments with the moniker RBC.

________________________________________________________

Advancement versus Apocalypse |  Rem Koolhaas

In this essay, which I gather is a short-form version of a presentation, Koolhaas provides a hybrid chronology of modern progress, focusing on  “…the coexistence of modernity and endlessly improvised, spontaneous conditions that don’t consume much energy or material. For me, a hybrid condition is the condition of the day.” (56)   Through searching history in the framework of ecological urbanism, he finds some precedents in the early indigenous knowledge of people, noting that over 2000 years ago, the basic tents of ecology were known, expressed in the vernacular, utilitarian architecture where people would “…build to be economical, logical, and beautiful.” (57)  This concept and focus on the site and siting of cities was echoed in the Ten Books of Vitruvius, through the Renaissance, and to the Enlightenment, which."...had a phenomenal effect on reason, in terms of triggering the apparatus of modernity in a surprisingly short time.” (58)

Thus along with the science and technology of modernity can the apocalyptic baggage best expressed by Malthus in the late 18th Century, and continued in more modern times through authors like Paul Ehrlich in the 1970s (Population Bomb) and even into today's discussions of peak oil and environmental degredation, referenced by James Lovelock (The Revenge of Gaia).

Koolhaas mentions an earlier formative experience with the ecological in the late 1960s, mentioning instructors working with tropical architecture that instilled a “respect for the landscape” and the ability to “look at other cities to see how they work , and to look at seemingly nonarchitectural environments.” (60) and expressed in attempts at the time to combine design and science such as Ian McHarg's 'Design with Nature' referred to as “...one of the most subtle manifestos on how culture and nature could coexist.” (62)

Koolhaas expands this with a quote from Frederick Steiner in‘The Ghost of Ian McHarg: 

“Almost 40 years ago, Ian McHarg proposed a bold theory and a set of ecologically related planning methods in Design with Nature (1969). While the proatical measures he proposed have been incorporated into subsequent design and planning practices, the theoretical implications have not yet been fully realized. Present-date forms of the model include the amalgam ‘landscape urbanism,’ with its focus on infrastructure an\d urban ecology, a hybrid discipline arguably indebted to McHarg while distinct in its avoidance of the more strenuous effects of his project.” (62)

In addition to McHarg the text mentions contemporary Buckminster Fuller's focus on the "...combination of nature and network...” expressed in this network diagram of global high voltage transmission networks (62) and also the work of the Club of Rome – Limits to Growth in 1972 (strangely enough a notable reason in Jonathan Franzen's recent book 'Freedom').

The environmental intelligence of the 1970s was soon quashed by the market economy, as Koolhaas mentions, “...had a devastating effect on the knowledge that had accumulated at this point.” (65)  The current situation of economics gain over ecological approaches has continued since the 1970s.

Shifting gears a bit, the current focus on ecological urbanism is the role of technology, specifically indicative of the engineering/technology will save us paradigm epitomized by Freeman Dyson – quoted in the NY Times: “...proposed that whatever inflammations that climate was experiencing might be a good thing because carbon dioxide helps plants of all kinds to grow. Then he added the caveat that if CO2 levels soared too high, they could be soothed by the mass cultivation of specially bred ‘carbon-eating trees’…” (66)


In addition to noting these radical technological fixes, Koolhaas also bemoans the current trend of boutique green-was expressed in the application of greenery to buildings, mentioning that, "Embarrassingly, we have been equating responsibility with literal greening." (69), mentioning specifically the Ann Demeulemeester store in Seoul, the work of Ken Yeang and the recent Renzo Piano design for the California Academy of Sciences building as examples of this travesty of architecture.

 This confuses me, as while I am not as excited about the green application of vegetation, the inclusion of the specifically bioclimatic architecture of Yeang seems misplaced, as it seems an expression of ecological urbanism.  Instead, Koolhaas finds merit in building new eco-cities in the desert, mentioning Norman Foster’s Masdar zero-carbon city as "serious", and a step forward from the boutique natural interventions of Yeang and Piano, mentioning:  “...we need to step out of this amalgamation of good intentions and branding in a political direction and a direction of engineering.” (70)

:: Masdar City - image via Menainfra

While a somewhat interesting exploration, it is somewhat circuitous and peppered with Koolhaas' self-professed doubt in the overall project, mentioning in the intro "I did not assume that anyone in the academic world would ask a practicing architect in the twenty-first century, given the architecture that we collectively produce, to participate in a volume on ecological urbanism..." (56)  This perhaps colors the text somewhat away from individual buildings and more towards the massive, techno-centric solutions from Koolhaas/OMA - such as the large-scale wind energy project in the North Sea mentioned in the end of the essay.

It's obvious therein lies a distancing from the individual ecological building in the context of these bigger, more significant infrastructural interventions - which marks a distinction, notably with the architecture of Koolhaas being rigorously programmatic, urban-engaged, but typically non-ecological.  Maybe the realization that one building here or there isn't going to be the solution is valid and worthy of discussion?  Is ecological urbanism about large-scale ecocities or infrastructure, or the aggregation of interventions at a variety of scales - maybe even including buildings?

(from Ecological Urbanism, Mostafavi & Doherty, eds. 2010, p.56-71)

Brief Thoughts on Binary Thinking

The on-going debate on LU/NU is interesting less for any content (of which there has been little beyond posturing and uninformed rhetoric), and more than its continuation of a history of binary discussions between oppositional actors that has occurred in many arenas, including a long history within urbanism and design.  Lest we think there is something special about this particular debate, it's important to remember some of those 'debates' (such as the visible rift between Mumford & Jacobs to name one of many - which is a fascinating dialogue worth some future exploration) have existed in the past.  These, instead of merely creating factions of us v. them, expand our understanding and discussions of larger, complex, urban issues.  A few thoughts on binary distinctions in general, therefore, is worthy of further exploration.

I always turn back to Elizabeth Meyer's essay in Ecological Design and Planning (Thompson & Steiner, 1997) where she elaborates on 'The Expanded Field of Landscape Architecture' and the tendency to provide 'binary sets' within discussions, such as architecture/landscape, culture/nature, and art/ecology.  The dualism in these positions are too distinct and limits potentials, positing that: “The scholar can develop theories for site description and interpretation that occupy the space between nature and culture, landscape and architecture, man-made and natural, and that are along the spatial continuum that unites, not the solid line that divides, concepts into binary opposites.” (p.74)  Instead, in the terms of landscape architecture, this requires "The rediscovery of the space between the boundaries – the space of hybrids, relationships, and tensions – allows us to see the received histories of the modern landscape as the ideologically motivated social constructs that they are… the gap between man and nature will be replaced with the continuum of human nature and nonhuman nature.” (p.51)

Having always been fascinated by the nature/culture debate, another resource worth mentioning is Placing Nature: Culture & Landscape Ecology (Nassauer, ed. 1997), which offers a range of essays in this realm, specifically focusing on blurring disciplinary and theoretical silos.  As Nassauer mentions in her concluding remarks: "Landscape ecology insistently confronts us with the complexities of connection. Rather than establishing boundaries to separate ecosystems or disciplines, it repeatedly points out their connectedness... [it] suggests that we should go beyond the boundaries precisely because sufficient answers are unlikely to lie solely within them. Respect for the complexity of the ecological relationships must balance out human propensity for know the world by simplifying it.” (p.165)

How we do that matters, but ecology offers some interesting parallels in thinking of urban systems, as both can no longer be perceived as closed, static, homogeneous collections, but rather are constantly evolving due to disequilibria, instability, disturbance, and flux based on a similar interactivity through reciprocal relationships between organisms and their environments.  This point is made thoroughly in Human Ecology (Steiner, 2002), who melds ecological thinking into our social construct at scales ranging from habitat to globe - describing an extension of the shift from deterministic ecological thinking towards a new ecology where humans are vital participants in the process.  In explaining this 'Subversive Subject', Steiner makes a case for ecological thinking as a new method for framing discussions, stating that "...human ecology emphasized complexity over reductionism, focuses on change over stable states, and expands ecological concepts beyond the study of plants and animals to include people.  This view differs from the environmental determinism of the early twentieth century."  (p.3)

I would make the case that this is the main thrust of landscape urbanist theory (i.e. it's not about landscape in a physical sense) in exploring a similar distaste with the concept of environmental determinism and looking to evolve this into more ecological thinking is mirrored in our changing from totalitarian urbanist schemes and deterministic urban strategies (closed systems) to methods that allow for temporality, market forces, chaos that fit within the complex mosaic that represent the modern metropolis.  These open systems, as mentioned by Steiner as possessing "...fluid, overlapping boundaries across several spatial scales from the local to the global," (p.4) and subsequently changes our approach to design and planning, where "...individual designed objects, be they buildings or gardens, are not viewed independently, but rather as parts of dynamic landscape systems." (p.10)  

This sort of thinking is missing from any single scheme of urbanism that claims to have 'the answer' to all of our problems.  Perhaps this is the inherent polarity in the distinction between NU (i.e. we have the answers) and LU (i.e. we have more questions) which leads to disagreement.  This is also represented in modern green building systems like LEED which are building-specific, because they can only exert influence over one distinct level of a complex, nested hierarchy of the entirety of  the urban realm.  A series of one-off, ultra-green buildings or dense, walkable communities are beneficial within a certain scale for sure.  The real question is to what extent to they solve larger problems of sustainability and issues of urbanism beyond their selected boundaries?  The either-or dialectic is not the issue but rather how we connect interventions within their larger (and smaller) contextual hierarchies, and how we general multiple solutions to deal with the complexities we face in addressing modern cities.  LU theory, for all its inability to articulate projects and its acknowledgment (not acceptance) of current urban issues (i.e. autos, suburbia) in my thinking isn't trying to occupy a binary opposite to NU (sorry Waldheim) but rather to offer a counterpoint to a larger urban methodology that is focused on product instead of process.

In this context, and shifting gears back to conflict for a second, I was struck by the parallels when delving into the great collection of essays 'Uncommon Ground' (1996), edited by one of my favorite writers, William Cronon, offers a wide discussion on the idea of nature in our modern thinking.  More exploration of that soon, but for now let's focus on the similarities inherent in debates on urbanism, in relation to binary thoughts related to 'environmentalism' and 'nature'  Cronon mentions, "...once we recognize that not all human groups and cultures view nature in the same way, it becomes at least more complicated to assert that one group's ideas of nature should take precedence over another's.  At a minimum, we need to enter into a dialogue with other people about why they think as they do... [and] we should be willing to question some of our own moral certainty in an effort to understand why we ourselves think of nature as we do, and why others do not always agree with us." (p.21)

By making a leap that substitution of the word 'urbanism' the same framework could inform our thinking in similar terms.  In conclusion, a wonderful quote can illuminate the recent LU/NU debate, particularly in relation to binary modes of thinking and the type of rhetoric that it has spawned due mostly to the previously mentioned, and much misguided feeling of moral certainty in one's particular viewpoint: 

"We live in a time when political discussion favors extreme positions and sound bites.  In the struggle to attract attention and support for one's own views, the temptation if very great to caricature those of one's adversaries.  The result it a rhetorical landscape of polarities, in which start oppositions arise and cartoons become our most common way of conducting what passes for reasoned debate.  In such a world, your either for the environment or against it, and any inquiry that points towards more challenging ways of framing the discussion can seem threatening.  The crucial task of self-criticism is all to easily avoided because it can seem to lend aid and comfort to the enemy." (p.22)

More Hidden Rivers - NYC

An interesting post from Urban Omnibus from earlier in January entitled 'Grey vs. Green: Daylighting the Saw Mill River' is less intriguing in design concept that in larger idea of envisioning the expression of the variety of waterways that are hidden/buried/forgotten within our urban areas.  As referenced by Eric Sanderson through  his work on the fabulous Mannahatta project "The movement of water is universal. What takes it out of the ordinary is the infrastructure we have built around and in spite of it. Mannahatta notes that there were once 34.9 miles of “rocky headwater stream communities” and 14.2 miles of “marsh headwater stream communities” on our island, in addition to numerous springs, ponds, and intermittent streams."


The idea of  a more artistic expression comes out in the great image from the article.  The idea, as mentioned in the caption: "Spanning the corridor between the 42nd Street/Bryant Park BDFV station and the 5 Av 7 station, Samm Kunce’s mosaic “Under Bryant Park” is an evocative imagining of the root and water paths behind the tiled walls. ."

The design concepts seem pretty standard fare visually, although the are made up of highly artificial and engineered system.  The authentic expression of 'system' seems an interesting challenge for designers, similar to restoration processes for the LA River which has elicited terms like 'Freakology' to describe the hybridized ecological system.

City Concealed: Staten Island

I previously featured a video from the online video series "The City Concealed" produced by Thirteen, a project of New York station WNET.  The series offers glimpses into some of the terrain vague of the metropolis by: "...exploring the unseen corners of New York. Visit the places you don’t know exist, locations you can’t get into, or maybe don’t even want to. Each installment unearths New York’s rich history in the city’s hidden remains and overlooked spaces." 

The alerted me to a recent video on the Staten Island Greenbelt, which is 2,800 acres of passive natural area and more traditional parkland, a short distance from Manhattan.

The City Concealed: Staten Island Greenbelt from Thirteen.org on Vimeo.

A bit of context from a location map shows the full extent of this agglomerated green zone slicing through the center of the island.

A close up shows some of the detail of the connected areas and the juxtaposition of the active and passive elements.

The proximity to Fresh Kills Park is obviously not lost on the potential for expanded greenbelt potential, connecting the southwestern portions to the new park, extending to the western shore of the island.

A quick tour of the recent videos has some great finds, including this one exploring the abandoned Hincliffe Stadium in Paterson, New Jersey and how it is slowly being enveloped by vegetation, and efforts to save this historic resource.

The City Concealed: Hinchliffe Stadium from Thirteen.org on Vimeo.

The City Concealed video series explores historical locations around New York City that are either off-limits to the general public, or are otherwise difficult or impossible to see. The City Concealed, now in its third season, is part of THIRTEEN.ORG’s original online video offerings for New Yorkers.

Destinations of the nine upcoming episodes include New York's last Greek Synagogue in the LES; the decommissioned Ridgewood Reservoir; the abandoned Ft. Tilden in The Rockaways; the closed-off High Bridge, plus a few more.

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.

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.

Ecology.Agency.Urbanism

I warn the reader that my take on the recent NOWurbanism lecture featuring Chris Reed, Randy Hester and Howard Frumkin may be skewed by a really bad cold and the influence of massive doses of cold medicine, along with spilling an entire water bottle inside my bag that literally muddied my notes into a semi-decipherable pulpy mess.  As all histories are individual, this will be my reading of the nights events (and I fear I will not do them justice).  But then again, perhaps this is the perfect storm of dissociation in which to warp and skew the voices into a coherent narrative.

I was really excited to hear from Reed, Principal at Boston-based Stoss Landscape Urbanism and adjunct associate professor of landscape architecture at Harvard GSD.  As recipient of the 2010 Topos International  Landscape Award, "...in recognition of the “theoretical and practical impulses the firm provides to the advancement of landscape architecture and urbanism as dynamic and open-ended systems.”  As a practitioner who embraces the project-oriented aspects of landscape urbanism, I think Reed is unique in straddling the line between theory and praxis - and approach that is often attempted, but rarely done in a legible way.  I was keenly focused on finding out the methods for achieving this balance.

Ecology.Agency.Urbanism

The bulk of Thursday's time was given to Reed's lecture entitled 'Ecology Agency Urbanism' in which he frames landscape and ecology in a context beyond the current concepts of 'sustainability' and 'LEED', arguing for the 'agency of ecology' that is not used as a palliative but as an instigator.  In our search for a positive performative approach, we often rely on the crutches of simple definitions or rating systems, which move towards luke-warm, incremental changes, but not paradigm shifts.

Some History

Reed first frames some of the historical elements of ecology as it relates to planning and design, mentioning Ian McHarg's ecological assessments (inventory, mapping, overlay) and giving value systems to data to use for design and planning-based decision-making.  While acknowledged as important in elevating the discussion, there is also the flip side of criticism's of this objectivty and quantification of processes, alluding to the lack of a cultural lens in which to perform interventions with this information.  The most interesting idea, according to Reed, from McHargian theory was that of 'propinquity', an innate acknowledgement of the proximity, but also the kinship of the environment and it's actors - aligning the needs of the people with that of the surrounding ecological landscape.

He follows this with the next phase of landscape ecology, best expressed in the work of Richard TT. Forman which "catalyze the emergence of urban-region ecology and planning", using the concepts of matrices, interconnections, and networks to express exchange of materials.  The major contribution of this is the visual, using mapping to acknowledge not a static ecological system, but to facilitate flows that observe an active and dynamic nature.   On a practical front, Reed mentions the work of Richard Haag and George Hargreaves as innovative early examples of built projects using these environmental dynamics as generators of form under the mantle of landscape architecture.  The realizations contributed to a conceptual shift of ecology from the static (equilibrium theory) to one that included fluctuations in response to disturbance and change.

The final phase came in some of the early large scale landscape competitions, such as Downsview Park in 1999, which featured time as part of the design brief.  All of the entires worked time into the solutions, which laid some foundations of modern landscape urbanism theories of indeterminancy.  Not the finalist, but of interest was the proposal from James Corner and Stan Allen, "Emergent Ecologies, which is described on the Downsview site: "The framework consists of an overlay of two complimentary organizational systems: circuit ecologies and throughflow ecologies. These systems seed the site with potential. Others will fill it in over time. We do not predict or determine outcomes; we simply guide or steer flows of matter and information."


Four Tendencies
The next section discussed the 'Four Tendencies' that have emerged into a set of typologies of ecological systems, summarized by Reed here (and hopefully captured in some sense of legibility):

1. Structured Ecologies:  Active habits of plant growth, water movement, habitat use - manipulated over time in response to change, factoring in resiliency and incorporating landscape as a dynamic field.


2. Analog Ecologies: Use ecological elements to achieve non-biological products, epitomized in the work of Ned Kahn and Chuck Hoberman.


3. Hybrid Ecologies:  Responsive design systems that tap into large scale system dynamics, including human and non-human interaction in space.


4. Curated Ecologies:  Structured interactions with dynamics over time, not under specific control, but poked and prodded - designers role shifts as project demands.

The work evolved from the Harvard GSD, particularly the work of Nina-Marie Lister, for a May 2010 event 'Critical Ecologies' which synthesized the historical and current practices of biology, horticulture, and anthropology as antecedents to design.  (need to find out more on what happened here, as it sounds like a great event with some amazing speakers.

Work of StossLU

In the next part, Reed explained some of the work of Stoss, to give a physical reality to some of the ideas of open-endedness and concepts in action. To provide a framework for these approaches, these were intermixed within a number of larger ideas.

Thicken the Surface:
Using the concept of multiple uses and meanings for land, imbued with both form and performance - but not strictly in a sculptural sense.  This best expressed in Riverside Park, in New Bedford, Massachusetts, an eco-park that elaborates the performance aspects of topography, with formal sculptural qualities as a result of the underlying processes.

Draw on Local Practices:  
The project mentioned was the Competition for the Herinneringspark in regional West Flanders, Belgium, which used ephemeral interventions over large spaces for this historical WW II site - specifically focusing on agricultural cycles to highlight specific forms.  (sorry, couldn't track down any pics on this one)

Flexible Spaces for Social Interaction:
Using the Erie Street Plaza in Milwaukee, Wisconsin as an example, mentioning the patterning of materials (lawn and pavement) and the interplay as a randomized surface that allows for a flexibility of uses.  The other aspect of interest was the connection to the water table and the fluctuating levels of moisture and the use of steam to melt portions of the snow for year-round use.

Open Ended Design:
The garden festival in Grand-Metis, Quebec is the example for open-ended design, 'Safe Zone' was designed with simple materials in new forms, for a flexibility of uses... a play area, but not prescriptive, rather a safe and injury free surface for experimentation and adaptable play (one as Reed mentions, kids get intuitively, but adults take time to adapt to)...

(more pics here on L+U)

Civic Scale:
A more expansive explanation included the concepts of civic scale, expanding some of the more ephemeral and small-scale interventions into significant projects in urban areas.  One example Reed noted was the Fox Riverfront in Green Bay, Wisconsin, which is built above a sheetpile walll, and required the manipulations of various surfaces to accomodate a range of spaces.  The stepped benches form seats and chaise lounges, reacting to the different heights of the subsurface conditions.

The overall site also responds to the flooding conditions that come up and over the bulkhead, creating a reactivated civic space while simultaneously incorporating a functional piece of civic infrastructure.

Engaging/Recalibrating Infrastructure
The representative project for this concept was the controversial (locally) competition for capping the Mt.Tabor Reservoirs in Portland.  Stoss's concept was one of the more innovative, blending a new ecology while creating a social spaces.

An Integrated Project: Lower Don Lands


A larger example of a project was the competition for the Waterfront and Lower Don River area in Toronto, Canada, which Reed explained in a bit more detail.  The concept (the competition eventually won by MVVA) by Stoss offers a chance to provide an integrated approach, with a goal towards both restoration of the Lower Don River and the subsequent urbanization.  This river first, city second does resonate with the landscape urbanism principles of new form-making driven by landscape/ecological processes.

The condition of the existing 90 degree bend of the river, and the need for a more modulated river/lake interface required designing a river, which had both a performative and aesthetic requirement.  This involved a couple of what Reed refers to as principles and flexible tactics:

1. Amplify the Interface: between the river ecosystem and the restored estuary
2. Hybridize the Parts: changes between armored and porous materials, restoring the marsh condition and then letting the ecological systems take over, which provides flood control while creating spaces for urban activities.
3. Modify the Harbor Wall:   establishing a vocabulary of marshes and channels, which form courtyards as catalysts with flexible programs.
4. Unique Building Typologies: Flexibility of form, and flow of landscape across spits and islands, then up the faces of the buildings - green machines.

As Reed mentioned, this provides an example of using ecologies as generative forces (agencies), which as seen from the above examples provides a snapshot into the conceptual framework that is applied to projects at a variety of scales.  Be sure to check out the full range of project work on the Stoss website and get more information on some of these projects mentioned.

Stay tuned for a synopsis of the Panel Discussion coming in a separate post.
Thanks to all the great folks at UW, as well as Chris, Howard, Randy, and Peter for the great after lecture discussions and dialogue.

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:

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.

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

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.

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.

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)
