WPA Video: Local Code / Real Estates

I managed to butcher the announcement of the WPA 2.0 finalists a few weeks back... (which should be up to date now)... and was made aware of it thanks to Ben Golder, one of the team members from the Local Code team. He recently sent me this link to a video of their project. I will post some more when they are available, but for now enjoy this one.

WPA 2.0 Student Finalists

As a follow-up to the previous post, the student award finalists were announced as well, including a few of the notables images from some of the entries.

“R_Ignite” was designed by four graduate students of the Manchester School of Architecture – Peter Millar, Jamie Potter, Andy Wilde and Stuart Wheeler. This proposal revitalizes port cities and greens the shipwrecking industry through the addition of recycling and social activities."

Additional finalists included:

St Viaduct: Polytechnic HighSchool & Transportation Center; Studio Three - Douglas Segulja - Parsons School of Constructed Environments

Fluctuating Freeway Ecologies; The Crop - Gary Garcia . Marc Yeber . Iris Tsai . Xiaoye Zhang - USC School of Architecture

urban ConAgraculture; Dale Luebbert - University of Nebraska

Cash for Clunkers = Bike Sharing for Chicago; M-Squared - Matt Moore IIT

Topographic Infrastructure: Hollywood Freeway Central Park; YMeng; Meng Yang; USC School of Architecture

Just the names themselves sound intriguing, and there will undoubtedly be some additional images of the rest of the student winners down the line a bit, so stay tuned. Amazing work and great to see the interdisciplinary nature of infrastructure realized with a mix of architecture and landscape architecture student's getting honored. I hope to follow up with some thoughts (beyond this simple rehashing on the words and images) in due time.

WPA 2.0 Winners

[post corrected on 12.13.09]

I have been remiss in posting about the WPA 2.0 competition beyond this initial post way back when... it's been exciting to see both the professional and student awards coming together into a fabulous compilation on information on the reinvention of public infrastructure. So alas, it w
as time to capture at least a portion of the great ideas that came from the submittals.



Carbon T.A.P // Tunnel Algae Park
The grand prize winner of the competition was: "... the brainchild of PORT architects Andrew Moddrell and Christopher Marcinkoski of Chicago and New York. The proposal uses algae pontoons to capture mobile-source carbon-dioxide emissions along New York City’s transportation arteries and employ them in bio-fuel production, creating an urban park with structured wetlands, aquatic and avian habitat, recreation amenities, as well as high speed bike lanes and public promenades. The jury... was unanimous in its decision, citing two primary qualities: The floating, carbon-capturing bridge between Brooklyn and Manhattan would be a visible marker for the tunnel hidden below, and the periodic rotation of the parkway across the river had the power to reshape the image of the city."

There is also a video of the winner here:



The remainder of the finalists are captured on the WPA site (provided by competition sponsor cityLAB), from this post on Bustler. The other five finalist entries are found below:

HYDRO-GENIC CITY, 2020
"Through the development of integrated, ecologically sensitive, and aesthetically compelling architecture, this proposal seeks to turn the often mechanistic infrastructural system of LA - in this case, the waterworks - into an interactive and sensory series of public nodes. As mist platforms/light rail stations, urban beaches, energy producing water treatment plants, solar-panel encased water towers, pools, and aquatic parking lots, these water-based landscapes become organizational moments for community building."




:: images via Bustler

Local Code / Real Estates
"Tapping into the Department of Public Works catalogue of San Francisco's "unaccepted streets" (those no longer maintained by the city and hence neglected and often impassable), this proposal utilizes various computer models and statistical data to determine and propose new public, park-based uses for these interstitial spaces. Over 1600 of these sites are available, a selection of which are analyzed for the proposal in terms of elevation and topography, microclimate, soil type, hydrology, population density and demographics, economics, crime, and existing networks to determine the most parametrically appropriate transformation of use."




:: images via Bustler

Coupling Infrastructures: Water Economies/Ecologies
"This proposal focuses on America’s impending water crisis, particularly in cities in the southwest where growth is high and water availability is limited, by rethinking water use, distribution, and storage. Using the Salton Sea as a model site, the proposal envisions “converting the Sea back to its recreational use while allowing multiple economic opportunities for the production of water, salt, and more efficient greenhouses.” Here “infrastructure [becomes] an extension of nature.” Island pods provide for salt harvesting, recreation, and new animal habitats."




:: images via Bustler

Border Wall as Infrastructure
“[T]here exists far more potential in a construction project that is estimated to cost up to $1,325.75 per linear foot.” Recognizing the high cost, limited effectiveness and unintended natural consequences of the new, multi-layered US/Mexico border wall (disruption of animal habitats, diversion of water runoff that has caused new flooding in nearby towns), this proposal names 30 alternatives (covering nearly the whole of the Mexican alphabet, literally from Aqueduct wall to Zen wall) that might better combat the energy crisis, risk of death from dehydration, disruption of animal habitat, loss of vegetation, negative labor relations, missing creative vision and lack of cross-cultural appreciation likely in the government sponsored version."

1,000,000,000 Global Water Refugees
"Combining the rust belts’ loss of population with its abundance of fresh water, this proposal outlines a strategy for redensification of under-utilized post-industrial landscapes (parts of Milwaukee, Buffalo, Detroit, Chicago, and Cleveland) by relocating populations threatened by water scarcity."

Urban Crude

One the most fascinating passages of the book 'The Infrastructural City' was the chapter on oil production that still existed in a variety of forms throughout the urban form. The fabulous Center for Land Use Interpretation (CLUI) has done some investigations, which are captured on a post in the Places portion of the Design Observer site.


:: image via Places

"Los Angeles is the most urban oil field, where the industry operates in cracks, corners, and edges, hidden behind fences, and camouflaged into architecture, pulling oil out from under our feet. . . . Los Angeles is an active laboratory for how to extract oil from a developed city, something more likely to occur as the world urbanizes. Generally considered unsightly, dirty, and smelly, the oil industry has had to develop defenses against the rising value of the land and the encroachment of housing and retail. Sound muffling technology, visual barriers, and the concentration of wells into smaller areas, using directional drilling techniques to access fields through diagonal and horizontal wells, are all technologies developed here."

One aspect beyond the mere existence of these in the city, but also interesting was the methods of hiding this infrastructure within the urban form. One of these is the Venoco Oil Field Tower, which is "...an urban drilling and work-over tower is clad in soundproof insulation, decorated during the permitting process".


:: image via Places

Or the Breitburn Energy’s Cardiff Well Site which has the "...drilling and work-over derrick is concealed within a tower which vaguely alludes to synagogue architecture."



:: image via Places

A slideshow offers many more images in typical CLUI style. It brings to mind the ideas mentioned in the recent post on Subnature, where we want the pure urbanism, but are often forced to incorporate some of the messiness of natural resources and industrialism in our cities - and what that leads us to come up with for ideas.

As We Found Them... As We Leave Them

A provocative image found in an email from the local Audubon Society email offers the visual of 'As We Found Them... As We Leave Them', a Jay “Ding” Darling cartoon from 1923, as a statement about the state of our rivers in the face of urbanization.



The reason for the email was an upcoming hearing on the Willamette River in Portland. The text:

"On Wednesday, December 16th at 630 pm Portland City Council will hold its first hearing on the North Reach River Plan. This is a unique opportunity to reverse more than a century of degradation in the Willamette River as it passes through Portland. The North Reach stretches 11 miles from the Fremont Bridge to the Confluence with the Columbia River. It is one of the most degraded stretches of river in the United States.


The North Reach Plan is the City's first major update to the zoning code and design guidelines for this stretch of River since 1987. The Plan took more than two years to develop and proposes more than $500 million in new infrastructure to support river industries and new trail alignments that will provide the public with greater access to the river. The Plan also proposes critical new strategies to protect and restore habitat in the North Reach. Specifically the plan proposes the following:

• Environmental Zoning to provide baseline protections for the most important riparian and upland resources;
• A system of 21 permanently protected restoration sites designed to allow listed salmon and steelhead to safely pass through the North Reach;
• A funding structure that requires industry to fully mitigate to replace existing habitat that is eliminated in the course of development and a small additional fee which will go towards supporting habitat improvement in the North Reach.

We expect strong industry opposition to this plan. Industry has been arguing to eliminate environmental regulations on industrial properties and to gut the proposed funding mechanisms. If they have their way, the regulations established under the new River Plan would be even weaker than the regulations that we have today---the regulations that have already allowed the North Reach to become the most degraded stretch of river in Oregon.
"

Portland Grid, revisited

The question of the efficacy of the grid system is continually interesting, and there have been some interesting conversations about this with a range of folks locally. Another resource to throw some information into this discussion is the recently released background documents in support of the Portland Plan. One worth checking out for any Portland-phile is the segment on Urban Form (it's a large file, so this is a link to all of the background reports).

Scrolling through it, I found this interesting two page study on block typologies, which mentions the ubiquitous 200' square blocks:


:: image via Portland Plan

From page 37-38 of the Urban Form document: "A city’s structure of streets and blocks serves as its urban DNA, shaping its development long into the future. While Downtown Portland’s system of compact 200' by 200' blocks is sometimes seen as Portland’s fundamental pattern, it covers only a small part of the city. As will be summarized in this chapter, Portland includes a diverse and varied range of urban patterns. These examples highlight the wide range of block structures found in Portland (they are not intended to represent what is typical or most common)."

This couple of pages continues to outline a range of variations, also giving an average size and location that they commonly appear within the city. The grid obviously starts to stretch in some areas, turning into a rectangular grid with one elongated side and the inclusion of alleys in some areas. These are bisected by some of the anomalous items like diagonal streets. There is also a larger retangular block size as growth sprawls out into Northeast and East Portland.








:: image via Portland Plan

The square and rectangular blocks degrade in a number of ways, including some neighborhoods that have a more diagonal grid that creates triangular blocks and open spaces. Subsequent iterations include more curvilinear blocks are rectangular grid but with undulating curves, and some more organic layouts that may or may not have been influenced by topography.








:: image via Portland Plan

As you can see, there is definitely an evolution away from the small grid, which is mostly located in the City Center and inner eastside. It's also interesting to see the changes and experimentation that happened as the city moves outward from the center. But wait, there's more... another set of typologies to augment these patterns that offers some more typologies, including the very archetypal Ladd's Addition, an beautiful oddity for sure, as well as plain ol' curvy sprawl. It's a fascinating study.


:: click to enlarge - via Portland Plan

These patterns aren't necessarily the all-encompassing group, but it does outline a vocabulary of almost 20 varieties that range from the prototypical 200x200 block. I spent a couple of days in San Francisco this past week, working on a project, and it was interesting to contrast a small grid with a comparably large one, particularly at a pedestrian scale. It was a block-by-block decision whether this made one or the other more successful - but it wasn't a particular winner either way. Along that line, check out my colleague Brett Milligan and a couple of posts on his Free Association Design blog about the grid and a case study of vertical subterranean structure from Guanajuato.

More to come on the comparisons, for sure and definitely more on the Portland Plan and associated documentation. For those interested, check out the latest community involvement dates to see where the Plan is going...

Size Does Matter, or Not

An interesting article in Planetizen called "Beloved and Abandoned: A Platting Named Portland" investigates one of the unique, frustrating and beloved quirks of Portland. This is, our slicework of 200 foot square blocks... making for a lot of roads, and development of tiny blocks. It's our burden to bear. The article is a fascinating ride - so check it out.


:: all images via Planetizen

The authors discuss the 'Hippodamian' grid, which is an interesting way of saying square, and relate it to current urban design theory and practice. "Current planning literature brims with references to "the grid" in juxtaposition with curvilinear and dendrite conventional suburban layouts. The "grid" as a network concept has been widely accepted and is now regarded as a superior geometry for laying out greenfield and infill sites."



There is also the reference to the success of Portland directly related to these small blocks, which I'd disagree with (as the authors soon do). I'd say Portland succeeds in spite of this phenomenon, and the issues pervade - as is shown with a reference to successful urban grids, mostly those of the non-square ilk. "Urbanists and romanticists have expressed equally strong sentiments about Paris, London, Barcelona, Curitiba, Amsterdam and Venice. Of the six, only Barcelona adopted the Hippodamian grid in 1859 for its vast expansion, and Venice, without a classic grid, is the preeminent pedestrian haven, yet neither city matches the urbanist’s praise for Portland. Whatever the mix of reasons, Portland dominates the American planners' imagination feelings and talk. Disentangling this intangible realm can be an elusive goal; grounds and figures on the other hand may produce tangible results."

A grid alone is not the recipe for success, and in practice there are few pure iterations of the grid, with zigs, zags, curvy spots, the axial geometry of Ladds addition, and many other quirks. As a fan of the grid for wayfinding and layout, there's something to be said for the rigorous adherance to the formality, which much theory has been laid out in curvy, suburban blah. Some support of the grid: "The degree of connectivity of the street network could count as another practical reason. 'Network', by definition, is a set of linked components, whether a spider-net, a fishnet, or the Internet - all networks connect. What distinguishes them is the manner, geometry and frequency of connection: leaf, tree, blood vessels, telephone and web networks are dendrite, hierarchical (fractal) but fishnets are not. Portland’s is a dense fishnet with nodes at every 200 feet, which produce 360 intersections per square mile -- the highest ratio in America, and 3 to 5 times higher than current developments. For example, older and newer areas in Toronto, typical of most cities, range from 72 to 119 intersections per square mile in suburbs and 163 to 190 in older areas with a grid. As connectivity rose in importance as a planning principle, Portland’s grid emerges as a supreme example.

Coupled with connectivity, its rectilinear geometry is indisputably more advantageous for navigation on foot, car or bike than any alternatives. Visitors often feel lost and disoriented in medieval towns and in contemporary suburbs and this feeling leads to anxiety and even fear and a sense that all is not well."



The grid is rightly stated as derived by speculators for maximum corner lots - not in the grand plan of some more model communities. The fact is, again, that the grid can improve or degrade the urban environment, as the authors mention, but success is not inherently depending on that as the only criteria. "Evidently, Portland’s founders either understood little about infrastructure costs or judged them irrelevant; a judgment that no planner, developer or municipality today would take at face value. When economic efficiency matters, Portland’s grid fails the grade."

In a theoretical sense only. There's comments from Sitte and Duany on the lack of art in the grid... but really is urban planning about art? Is curvy and artistic more successful in an urban context? I doubt it. Anyway, the fact that our grid, much like the national grid system, is overlaid on a extant topography in somewhat irresponsible ways have led to issues with erasure and negative impact on natural hydrologic patterns, which only bend when topography and streams are too steep or significant to pipe, grade, and cover over. Also, the sheer amount of street paving is significant, as our small blocks lead to significantly more stormwater impacts. This however, has been the genesis for innovative strategies such as green streets to combat this - sort of making a silk purse out of a bad grid.



While it may be easy to ignore progress in combating our bad grid, it's again a pointless thought exercise (these adaptions in the following paragraph are the lifeblood of modern urbanism, as we can't recreate what has already been created). Thus, it's interesting to think of ways of refuting the present by showing how the past is flawed:
"The ordinary impression on the ground that the Portland grid 'works' in contemporary traffic conditions is casually taken as a sign of suitability. This view obscures an entire century of engineered physical, mechanical and management adaptations which are overlaid on the 1866 platting. Remove these (in a thought experiment) and imagine the outcome. Clearly, an ill-suited geometry is made to work with interventions such as dividing lines, medians, traffic signs, traffic lights, directional signs, bollards, street widening, one-ways, traffic circles or roundabouts and many others."

I think that's called adapting to change, but then again, it's a thought experiment, so fun nonetheless. As the authors conclude:
"For reasons of land efficiency, infrastructure cost, municipal expenses, rainwater management, traffic safety and flow, and the demand for increased pedestrian share of public space, the praised, pure Portland platting will likely not find new followers. Portland will remain a adored and beloved by urbanists, but her Hippodamian grid layout seems destined for the archives, abandoned as a good idea of a byegone era. This transcendence leaves urbanists, who seek to regenerate a contemporary urban pattern that is as pure, complete and systematic, looking for alternatives: ones which excite the same first blush of adoration and delight and lead to a deep abiding love, but also hold up to intense scrutiny of their economic, social and environmental performance."

I agree with the main tenets of their thesis (and it's a great notion and read) and frankly think the grid is a pain in the ass, but it's one of those theoretical arguments that really doesn't mean much in terms of modern urbanism, particularly in a city that plans things to death and beyond. Few if any new cities are built from scratch with no existing contextual framework - so maybe in the few new communities, a particular utopian grid system can be applied - probably modeled after the latest New Urbanist theory. It'd be interesting to imagine a re-thinking of the 'Hippodamian' grid being retrofit, as is, into something else in Portland - elongated, filled in, abstracted into a more pure and reasonable pattern, with streets removed to be open spaces, bikeways, and other green infrastructural systems. But the question is moot, a thought experiment if you will, and like it or not we are stuck with our pattern.

We deal with it, we plan around it. We love its street/building staccato chatter back and forth, with our 360 intersections per square mile, and we curse the stop sign hovering on your bike every 200 feet, waiting for that car to come zipping by take you out. It makes life exciting. But, in general it doesn't mean much, and isn't as derogatory to a high quality public realm as implied. Portland isn't to be copied for urban form, and really shouldn't be degraded for a grid system that was done without regard. We're known for for innovation and foresight in policy, transportation, stormwater management, and other factors. Many of these come from the very problems that arise from our back-assward small grids. But it works, because sometimes a grid is just a grid.
