Urban Planning Tools for Climate Change Mitigation
"Land use and urban form are key contributors to greenhouse gas emissions (GHG) through the physical arrangement of streets, building types, and land uses that influence vehicle use and energy consumption in buildings. City and regional officials now facing new emissions reduction requirements are increasingly turning to urban design as a key component of climate mitigation. But, this approach requires decision support tools that illustrate the GHG implications of land use and transportation options. While a wide spectrum of tools currently exists, few have the capacity to work simultaneously at both the regional and local scale, or to capture both building performance and transportation demand analysis.
This report reviews existing tools by scope, scale, methodology, and policy support, and presents four case studies illustrating how existing tools at various stages of development have been used. "
Forget Curbing Suburban Sprawl (MIT Technology Review)
I have some questions about the source of this report/ research, which claims that density (including examples such as Vancouver's eco-density) "would yield insignificant CO2 reductions."
QUOTE
Even if 75 percent of all new and replacement housing in America were built at twice the density of current new developments, and those living in the newly constructed housing drove 25 percent less as a result, CO2 emissions from personal travel would decline nationwide by only 8 to 11 percent by 2050, according to the study. If just 25 percent of housing units were developed at such densities and residents drove only 12 percent less as a result, CO2 emissions would be reduced by less than 2 percent by 2050.
UNQUOTE
I guess the problem is with defining real density as a mere "twice the density of current new developments": if you consider that new developments include suburban greenfield spreads on 1/4 to 1/2 acre for each SFH, then doubling that density really doesn't amount to much.
Further down, the report just makes the case for building more fuel-efficient cars - so maybe that's where the report's agenda originates.

Jane Jacobs’s Legacy by Howard Husock, City Journal 31 July 2009
Great review by Howard Husock of 2 new books about Jane Jacobs: Anthony Flint's Wrestling with Moses, and Glenna Lang and Marjory Wunsch's Genius of Common Sense.
Love this quote, which Husock provides, from Jacobs: “To approach a city or even a city neighborhood as if it were capable of being given order by converting it into a disciplined work of art is to make the mistake of substituting art for life.”
Why do I single this one out? Because it takes aim at the "aesthetes" who infest our midst (even in Victoria, BC, at the City council level and beyond).
Jane Jacobs vs. Robert Moses
A review of Anthony Flint's "How Jane Jacobs Took On New York's Master Builder and Transformed the American City."
QUOTE
Now there's a book that shows how these mythic characters shaped each other's work and reputations - a volume that leaves me wishing there was some way today to combine the best traits of both.
(...)
Make no mistake, Jacobs is the hero of this yarn. But in the epilogue, Flint addresses our ever-changing urban dynamics, where Jacobs' quest for "thoughtful citizen involvement" has morphed into "all-powerful neighborhood residents, who seek conditions to stay exactly as they are and reward politicians who agree with them."
Which sounds a lot like San Francisco, Berkeley and every other city [Victoria!] where process is more important than results. All the protections we've put into place, such as environmental reports, become weapons that can be used to derail anything that anyone dislikes.

Where 2.0 Preview - Building the SENSEable City - O'Reilly Radar
James Turner interviews Andrea Vaccari of MIT's SENSEable City Lab about using internet and mobile technology data (generated by citizens in their day-to-day lives) to figure out how "digital technologies are evolutionizing the way we live in cities." (Not sure about turning EVOLUTION into a verb...)

JT: In a future world where this is more pervasive and available rather than being a one-shot, how would you see urban planners and governments using this data?
AV: Well, for the urban planners, there is a big, big revolution going on. What happens today is that policies and plans are thought by assumptions. And their effects and imports can be evaluated only after a long time that they are implemented because, again as it was seen before, gathering this information is expensive. It's costly. It's cumbersome. So it's really impossible to get this information in real-time. What is going to happen is that instead of planning the city, the urban planners would actually have to program the city, to configure [it] in real-time because information will flow in real-time. So if you change the direction of the one-way road, you will see almost immediately what the effect on traffic is. If you close an area to cars, you can see immediately what will happen into the mobility in general. And if you create public spaces in a place rather than another, you will see immediately how people will react to that.

I recently saw some comments about our work that were asking what's the function of these visualizations. And I have to say they are very useful. And they are extremely important in two different ways. On one side, yes, they are helpful to inform the citizens to educate, in a sense, the public to understand this kind of information; to make them understand that their actions build up on an overarching dynamic system which is the city that really is built of individual choices. But these individual choices emerge as one unique entity which is the city again. So as we somehow try to explain how financial markets work by showing some graphs or charts at the end of the news on TV or on newspapers, I think that we will have to do the same to inform the public about these issues and to let them understand what it means. On the other side, these visualizations are extremely helpful and I have to say successful in helping those who are stakeholders in this revolution, as I was saying before, which includes telecomm operators or municipalities in getting interested into this analysis, in understanding the potential. And really by seeing this data visualized, the decision-maker can grasp it. And these visualizations helped us collecting some of the data that we then used for our quantitative analysis.

LimeWire Creator Brings Open-Source Approach to Urban Planning | Epicenter from Wired.com
Mark Gorton, software entrepreneur, turns to urban planning (transportation, specifically), using opensource to revolutionize planning.
QUOTE
You might call it a "P2P-to-people" initiative -- these efforts to make cities more people-friendly are partly funded by people sharing files.
That's not the only connection between open-source software and Gorton's vision for livable cities. The top-down culture of public planning stands to benefit by employing methods he's lifting from the world of open-source software: crowdsourced development, freely-accessible data libraries, and web forums, as well as actual open-source software with which city planners can map transportation designs to people's needs. Such modeling software and data existed in the past, but it was closed to citizens.
Gorton's open-source model would have a positive impact on urban planning by opening up the process to a wider audience, says Thomas K. Wright, executive director of the Regional Plan Association, an organization that deals with urban planning issues in the New York metropolitan area.
"99 percent of planning in the United States is volunteer citizens on Tuesday nights in a high school gym," Wright says. "Creating a software that can reach into that dynamic would be very profound, and open it up, and shine light on the decision-making. Right now, it becomes competing experts trying to out-credential each other in front of these citizen and volunteer boards... [Gorton] could actually change the whole playing field."

Larry Beasley's Simple Plan, by Frances Bula Vancouver Magazine
First page of a 10-page piece on Larry Beasley & co., and how other cities are adopting and adapting the "Vancouver model." It's a bit short on substance, but there are some interesting bits if you're willing to scroll across all 10 pages (each page is very very short - just a paragraph or so). Not sure why Vancouver Magazine presents articles in such an annoying format, but there you have it...
The Housing Affordability Problem Has Not Gone Away
Excellent blog post by Donald Elliott on why and how (un)affordability is systemic, and what (little) steps municipalities can take to mitigate the problem.
QUOTE
What can local government do? It cannot solve the macro-economic problem, but it can remove barriers that drive housing prices even higher than they need to be. Minimum lot size and minimum house size requirements are two of the main culprits. Artificially low multi-family densities are another, and narrow definitions of allowable housing types are a third.
UNQUOTE
-
Over the past two years, news from the housing industry has not been good.
-
So with prices falling, the housing affordability crisis must now be behind us – right? Wrong. In A Better Way to Zone I describe the housing affordability crisis as a structural problem of the U.S. economy and that is still true. Business cycles come and go, and this recession will in time bottom out and the housing economy will rebound. The long term effects may be a slight lowering of average housing prices – but not much, and not over the long haul. The key problem remains – the U.S. economy is simply not creating jobs that pay (on average) what it costs to build new housing (on average) and that gap continues to widen.

How to Create a Vibrant Waterfront | Project for Public Spaces (PPS)
Portal page for two additional links, "10 Qualities of a Great Waterfront" and "The 9 most important steps in revitalizing a waterfront." The main worry for the authors here ("A common challenge is how to revitalize places where the river, lake or sea has been cut off from the rest of town by wide roadways or hulking industrial facilities") doesn't apply to Victoria, whose waterfront is *not* cut off by road arterials or industrial areas. But in general terms, there are still some nuggets on the linked-to pages.
Protein® Feed | To Tackle Global Warming, California Takes Aim at Sprawl
Interesting short notice by Adam Stein about California's proposal to "pass legislation that would harmonize regional planning efforts with the state’s overarching goal of reducing greenhouse gas emissions. The most ambitious anti-sprawl legislation in the country, the bill seeks to coordinate housing, transit, and commercial development to reduce the impact of growth on the environment."
Stein reviews this in relation to Robert Bruegmann's "Sprawl: A compact history," which he happens to be in the middle of reading. Some interesting thoughts here on whether or not sprawl can really be mandated away. Also, not mentioned directly, but I can't help but hear Jane Jacobs, too, warning about restrictive overplanning...
-
Although not quite pro-sprawl, the book is decidedly anti-anti-sprawl, portraying efforts at shaping or controlling land use as largely the outgrowth of shifting and highly subjective aesthetic standards that disregard the desire of ordinary citizens for privacy, mobility, and choice.
-
Without entirely dismissing the problems associated with sprawl, Bruegmann suggests that many of the proposed solutions are destined to fail, either because complex urban systems respond in unexpected ways to simplistic planning measures, or because such measures offer fragile levees against so strong a flood of consumer desire for room to stretch out.

A design-savvy city defined, by Knute Berger (Crosscut Seattle)
For future reference: Berger's article about a report by architectural firm RMJM, which identifies America's top 10 best-designed cities. His article focuses on the aspect of heritage preservation, which factors into RMJM's weighting and criteria, and he notes that Portland seems to beat out Seattle.
From there, Berger segues into whether or not (or to what extent) citizens are "pleased with their urban architecture," and observes that only LA residents are "less happy with their city" than Seattlites. (I'm not sure how he manages the leap from heritage preservation to 'being pleased" by contemporary/new architecture, but there you have it.)
Anyway, the really useful thing about this article is that Berger lists the 7 categories RMJM used to answer the question, "what makes a design-savvy city?", and also summarizes each aspect (with commentary of his own, in italics). All in all, the list makes a great framework for thinking about urban design.
-
Public transit and urban infrastructure: Public transit systems can't stand still, even in mature transit cities like Boston and New York.

Portland was off the charts in transportation favorability, rating a higher approval than any of the top 10 cities at 79 percent.

With Gas Over $4, Cities Explore Whether It's Smart to Be Dense - WSJ.com
Have had this article open in a browser tab for days now -- time to bookmark. Along with posts by CEOs for Cities, or Richard Florida, this article too points to the effect that gasoline prices are having on suburban housing, and on the "sudden" desirability of urban living. (Well, I say "sudden" because I've *NEVER* understood why anyone would want to live in suburbs instead of living in cities/ densely packed neighbourhoods where you just have to walk a block or two, or less, to find social activity...)
From the article, QUOTE:
"Expensive oil is going to transform the American culture as radically as cheap oil did," predicts David Mogavero, a Sacramento-based architect and smart-growth proponent.
(...)
Even though the area's housing market has been wracked by price drops of 25% in the last year and one of the highest foreclosure rates in the country, Mr. Friedman says he already has sold nine of 28 town houses near downtown that he recently completed, and three more are under contract, "which is not bad considering the dismal state of the Sacramento real-estate market."
Mr. Morris, the developer, says the housing downturn is hurting the places that have the "dumbest growth. Smart growth works when the rest of it doesn't."

Looming Debate, by Veronique Vienne (Metropolis Magazine)
Interesting article (with some inaccuracies, too), focused chiefly on Bertrand Delanoe, the "Situationist"-inspired left-leaning, assassination attempt survivor and openly gay mayor of Paris, who gets blind-sided by Nikolas Sarkozy, the pro-business president of France, who wants Paris to be a bit more get-go-ish. Delanoe is on the side of the human-scale advocates who want to preserve its "charms," whereas Sarkozy doesn't mind a tall building or two. The article is interesting because it's one of the clearest outlines I've seen so far on making political linkages between certain attitudes toward modernization and height in Paris, vs preservation (and rejuvenation) of what that city's status quo as well as historical "essence" (at least mid-19th century onward) is.
-
Add Sticky NoteOne of Delanoë’s priorities has been to blur the line separating affluent Parisians from their often less privileged neighbors. In the last decades, Paris has steadily lost its working-class residents, who migrate to poorer bedroom communities beyond the city limits—a trend Delanoë wants to stop.
- Well, good luck. You can "want" to stop something like that, but that won't make the inner Paris more affordable or make land values drop. - on 2008-07-09
-
Whether it will work remains to be seen, but this solution is a typical Delanoë move. The former head of a PR agency, the mayor likes projects that “speak”—those that tell a good story and make his political intentions clear.

Generative methods in urban design: a progress assessment, by Michael W. Mehaffy - Journal of Urbanism: International Research on Placemaking and Urban Sustainability
Have only skimmed this so far, but worth going over in detail. Mehaffy focuses on Christopher Alexander's 1987 work, A New Theory of Urban Design, which was inspired by Jane Jacobs's 1961 work, The Life and Death of Great American Cities. Some of Alexander's ideas have been incorporated by the New Urbanists, and Mehaffy's article traces their "setbacks and shortcomings, and significant opportunities still remaining."
In Defense of Townhouses — Sightline Daily (formerly Tidepool)
- great article by Eric de Place on why so many new TH developments are so ugly. As his lede says, "How parking laws make housing expensive. And ugly."
-
Some of the new townhouse developments are pretty bland, and many seem divorced from the street. But why are the designs so flawed?
-
Here's one explanation. Nearly every townhouse in the city is required by law to provide offstreet parking. Since cars don't fly, the practical effect of the minimum parking regulations is that each and every townhouse has a garage on the bottom floor. And these garages are often the prime culprit in walling off the townhouses from the street, and of sending the residents upstairs.

"Don't be dense" by Zev Yaroslavsky - Los Angeles Times
"The debate about the availability of housing in Los Angeles and the city's development policies has been testy but long overdue." An interesting article by Yaroslavsky that initially makes the reader think that he's advocating a sort of nimby-istic "pulling up the drawbridges" mentality, but if the reader perserveres to read the entire piece, it seems his suggestions are really LA-specific. They're not necessarily in conflict with infill development; development around transit routes & hubs; and creation of density in areas that really need it (in our case, downtown). He does bring in late 80s experiences, however, which make you wonder if things haven't irrevocably moved beyond thel contexts he's referencing.
-
The debate about the availability of housing in Los Angeles and the city's development policies has been testy but long overdue.

Fueling public outrage over growth policies that would significantly increase density are well-grounded fears that, in the clash between overdevelopment and neighborhood preservation, the developers will prevail.

"Star Cities: The World's Best-Known Architects are Turning to Planning" by Joan Ockman - Architect Online
"Joan Ockman asks: Is a new form of urbanism emerging?"
"THE MID-TO LATE ‘90S saw the realization of several colossal redevelopment projects in which superstar architects were called upon to supply window dressing for the transformation of dysfunctional urban districts into tourist and consumer meccas, from Times Square in Manhattan to Potsdam Square in Berlin. But it was the triumphal opening of Gehry's Guggenheim Museum in Bilbao, Spain, in late 1997 that appeared, to architects, nothing short of a miracle. Gehry not only delivered a more optimistic, less intellectualized, and visually ravishing vision of architecture's potential and one, moreover, that innovatively integrated but was not entirely determined by new technologies; against all odds, he showed that it was possible to regenerate an entire city with nothing more nor less than a single, singular building."
This is an important article that has some specific relevance also for my concerns around the praxis of a local architect here in Victoria who thinks he can "envision" a certain kind of urbanism (low-rise) for this city. Should an architect be an urban planner? Can s/he be good at both? Ockham's article suggests it ain't necessarily so.
-
Add Sticky NoteThe first glimmer of real consciousness among architects concerning the inevitability of a new scale of architectural operations came in the early 1990s, when Rem Koolhaas, caused to rethink his worldview by his commission to design a new city center for Lille, France—an assignment that entailed a massive and apparently traumatic (for him) expansion of his previously modest-sized practice—came to reflect on “the problem of bigness.” Koolhaas shrewdly grasped that the global reorganization, expansion, and consolidation of late 20th century capital implied the emergence of a commensurate form of architecture. He envisaged an architecture of bigness more akin to the complexity and unscriptedness of the city, however, than to Architecture with a capital “A.” Bigness, as Koolhaas theorized in his book S,M,L,XL, required a giving up of “architecture's compulsive need to decide and determine” and a “surrender to technologies; to engineers, contractors, manufacturers; to politics; to others.” However much of a historical symptom, or pragmatic rationalization, this theory was in itself (especially in the case of a personality as controlling as Koolhaas), there is no doubt that it created an irreconcilable contradiction for architects: between design and nondesign; form and formlessness; heroic monumentality and sheer, dumb size.
- - scalability matters, and has an effect... - on 2008-03-30
-
“the disconnect between Bilbao the brand and Bilbao the city” remains palpable. Moreover, a surfeit of “icon buildings,” however creative and well-designed, especially in cities that have little else visually to recommend them, runs the risk of engendering architectural cacophony and ennui. In the case of Rotterdam, a Dutch city that has become a veritable architectural theme park with prominent contributions by Foster, Helmut Jahn, Renzo Piano, Wiel Arets, Ben van Berkel, and others, the skyline from certain viewpoints takes on the quality of a surrealist montage. If the icon derives both its logic and its energy from its uniqueness and difference from its surroundings, then its proliferation can only cancel the effect.

"Saint Brad" by Andrew Blum (Metropolis Magazine)
As I don't follow celebrity news, I had no idea that Brad Pitt is a "design junkie" or a pivotal mover-and-shaker in the rebuilding of the Lower Ninth Ward in New Orleans. (I barely know that Pitt and another actress -- Angelina Jolie? -- are linked/married/ or something... d'oh... )
Andrew Blum's article shines a good light (good as in "kind" and "illuminating") on Pitt's efforts, as embodied in the non-profit he started called "Make It Right" (MIR). And it does an excellent job educating me on the bizarre, yet potentially wonderful, nexus of pop culture/ money/ starchitecture momentum that Pitt has engineered.
The list of star architects makes my jaw drop; Blum discusses their efforts, and doesn't hesitate to poiint out where some of them go wrong (and others get it right). As Blum puts it, "If Pitt can pull this off, he will have transformed a swath of the Lower Ninth Ward, a neighborhood symbolic of everything rotten in America, into one of the world’s most design-intensive sustainable communities."
The article is well-illustrated (Blum's blog doesn't have the illustrations, but this link to Metropolis Magazine does).
-
Pitt’s new nonprofit, Make It Right, wants to help them “get a house” by providing the difference between their assets and the cost of rebuilding. The catch was that they had to choose one of the sustainable designs by 13 different architects—an amazing list that included Thom Mayne, David Adjaye, Shigeru Ban, and Kieran Timberlake.

Are you bringing these architects here, I asked, because you enjoy working with them? “That’s one of the benefits certainly, but it’s not the driving factor.” So why do it? Why bring not just architects here but some of the world’s best? “I’ll tell you why,” Pitt said, leaning forward and rubbing his hands together. “Because these people suffered a horrific event, and truthfully great injustice in the aftermath, and they’re still suffering that injustice.
<!-- End of Paragraph 1 --><!-- Beginning of Paragraph 2 -->
So what are you going to follow that injustice with? Crap houses with toxic materials and appliances that run up their electricity bills and may lead to a foreclosure? I mean, really. This to me is a social-justice issue. And to create something that’s equitable and fair and has respect and provides dignity for the family within is absolutely essential to rebuilding here.” - 14 more annotations...
Städtezerfall: München verschwindet
- interesting article on Munich's "caught in aspic/ amber" mentality of resisting modernism, as well as height, which relates to Social-Democrat long-time mayor Georg Kronawitter's argument that Munich must be small and surveyable, which the author argues contributed to rent inflation and exacerbated problems of affordability generally. Kronawitter also had this dimwit idea that no new buildings anywhere in Munich could exceed the Frauenkirche (99m) in height.
