This spring I presented The Interventionist's Toolkit
at a symposium hosted by the University of Sydney's Faculty of Architecture, Design and Planning. The Right to the City
, which featured an exhibition
along with the symposium, brought together architects, artists, historians, theorists and journalists; organized by architect Lee Stickells and artist Zanny Begg, the program took geographer David Harvey's 2008 essay "The Right to the City" — with its evocation of Henri Lefebvre’s influential 1968 book — as its critical springboard. As Harvey wrote: "The freedom to make and remake our cities and ourselves is, I want to argue, one of the most precious yet most neglected of our human rights." 
In recent years this argument has become a rallying cry for activists who oppose the neoliberal politics and policies of the contemporary city. There's a romantic appeal, maybe even a sense of imminent empowerment, in the prospect of remaking our cities and thus ourselves — a notion that if we change our environments we will change our lives, or vice versa. But ever since the symposium, I've been wondering about how we might evaluate the results of those freedoms. How to rate the diverse architectural actions and urban interventions that seek to remake the city? Do knitted cozies for stop signs
or street furniture made from discarded pallets
rank higher or lower than municipal cultural events? How do we measure the impacts of ambiguously defined and informal activities that are not only creative and civic but also — lest we forget Harvey's ourselves
— emotionally charged?
At the symposium, I shared the panel "Tactics for DIY Cities" with Slovene artist/architect Marjetica Potrc, who showed The Cook, the Farmer, His Wife and Their Neighbor
, a community garden/kitchen/collective artwork in the Amsterdam suburb Nieuw West that she created with the design collective Wilde Westen in 2009. The difficult question of evaluation dominated the Q&A that followed our session — and even in an academic setting, where one might expect cool objectivity, it was a hot potato. I tried to pick it up. I suggested that the evaluation of individual projects would be a futile pursuit. It would hamper our ability to take in the larger picture — the networks of practitioners and the diversity of tactics — at exactly that moment when social media are enabling these ground-up initiatives to flourish. But while I believe this to be true, it was also a dodge — a way to forestall judgment and see where these practices are heading.

For one audience member, however, this would not do. For this interrogator, a television program that aired on Australia's Ten Network for a few months in 2009 exemplified the need for quick judgment. The program, Guerrilla Gardeners
, followed the efforts of a half-dozen good-looking eco-warriors as they made unauthorized forays onto vacant public lands with the goal of transforming underused eyesores into blooming gardens. Lobbed from the audience, guerrilla gardening landed with grace of a seed bomb, making for a weedy thicket that Potrc and I were left to hack through — and highlighting just how difficult it is to judge such projects. The heated questioner was apparently offended that the activity of guerrilla gardening — a form of tactical urbanism and ecological activism — had been co-opted by the commercial interests of one of Australia's major networks. She wanted us to join her in swiftly dismissing the show as a mainstream opiate. But is a network-sponsored urban agricultural intervention any better or worse than a rooftop farm created by Brooklyn foodies or an old-school community garden tended by inner-city communitarians? Is urban gardening about lifestyle or politics? Is it activist or bohemian bourgeois? That day in Sydney the emotions ran high; identity was at stake.
And the answers aren't clear. If what we value is political radicalism, then Guerrilla Gardeners
might actually come out on top. The half-hour program was canceled after just a few months because it seemed to sanction trespassing; the show provoked controversy because municipal governments rejected the unlawful landscaping on their property. Although lighthearted and aimed at a wide audience, Guerrilla Gardeners
ultimately promoted an interventionist ethos that runs counter to NIMBYism. But if we award gold stars to social justice writ large, then it's The Cook, the Farmer, His Wife and Their Neighbor
that we'll applaud; this collective artwork represents a fully engaged community action that celebrates local food production. Located in a postwar modernist suburb in the Geuzenveld-Slotermeer district, the project transforms an underused green space into the site of citizen agriculture. The artists and designers established a structure — both social and architectural —in which gardening can bring together residents of the multicultural Amsterdam neighborhood. Yet the project was realized in collaboration with a major institution, the Stedelijk Museum. Does this kind of association with an established cultural arbiter knock points off for authenticity?
Urban gardening is one of the most popular tropes to emerge from the DIY urbanism trend. It's second only to food trucks. Today, in fact, the old "roach coaches" of an earlier era have emerged as mobile foodie magnets, catering to a new generation of gallivanting gastronomes — to the point where even when the food truck tactic is deployed in the cause of social justice and community outreach, its popularity complicates the issues. Let's look at two mobile food education centers: Jamie Oliver's Food Revolution
semi-truck (designed pro-bono by the Rockwell Group) and the Mobile Food Collective, developed by the Chicago-based alternative design school Archeworks. The projects are similar — both are mobile and come equipped with a pedagogical imperative to raise awareness about food and the food chain, from farm to table, within urban communities. Oliver’s truck, of course, is one component of a multinational corporate brand that includes a television show, cookbooks, restaurants, a foundation, not to mention the imprimatur of a TED Prize and an MBE. The 18-wheeler not only has a full teaching kitchen; it's also got an inflatable band shell that resembles the pneumatic spectacles imagined by Ant Farm and Archigram; and it's all tricked out in revolution-inspired graphics — painted onto the side of the truck is a raised fist brandishing a spoon. The Food Revolution truck partners with the California Endowment and operates in the Los Angeles school district. Every part of the project is keyed to high-profile outreach.

A more grassroots effort, the Mobile Food Collective
is a lightweight, portable structure constructed by Archeworks students from building materials donated by a Chicago recycling nonprofit. The design centers on a long wooden table, with file cabinets serving as both storage and seating. It's suitable for sharing meals as well as hosting workshops that address the social and economic issues surrounding food production. Archeworks
also created a fleet of bikes and trailers to boost what it calls a "cultural infrastructure" — partnerships with neighborhood nonprofits, urban farms, local groceries and area restaurants. The MFC is designed to be nimble and comparatively low-cost; yet it still depends upon institutional networks for funding and operations. The project was funded in part by a grant from the Graham Foundation for Advanced Studies in the Fine Arts, and in 2010 it was showcased in the U.S. Pavilion at the Venice Biennale. Is one food truck more or less legitimate? Do we judge on the basis of intent or content, audience or producer, reach or outreach?
In architecture, such questions of impact and functionality would fall under the rubric of "post-occupancy evaluation." (To be sure, POE is a practice that has yet to be fully embraced by the profession.) The performance of a structure can be measured using a variety of metrics: annual energy use, number of visitors, user productivity, etc. But when dealing with mobile and ephemeral works that skirt the edges of activist art and community organizing, the process of evaluation becomes more complex: the hard facts, the data that might influence policy or spice up a grant proposal, are elusive. As a result, as often as not it's sheer popularity — presence in print and online media — that becomes the default arbiter. And as with any media-driven contest, there's a real risk that the know-how to represent and market a project will trump the more substantial matters of content, impact and value.
Making these determinations becomes more problematic as the whole concept of what I've been calling in this series "provisional, opportunistic, ubiquitous, and odd tactics in guerilla and DIY practice and urbanism" is picked up by larger organizations, all brandishing their own urban design agendas. In late March, for instance, the downloadable pamphlet Tactical Urbanism: Short Term Action | Long Term Change
was extensively blogged, liked on Facebook, and retweeted. The 25-page booklet, which referenced "The Interventionist's Toolkit" as source material, pulled together a dozen case studies as a guide for launching temporary, low-cost urban experiments. Compiled by Mike Lydon, Dan Bartman, Ronald Woudstra, and Aurash Khawarzad, the Tactical Urbanism booklet was produced by the Street Plans Collaborative (Lydon is the founder) and the Next Generation of New Urbanists, or NextGen, as they like to be called — signaling, perhaps, a distancing from the group's New Urbanist roots. And as the popular publication circulated around the Web, the relationship of this material to the Congress for New Urbanism dropped away, just as the words New Urbanism slipped from the organization’s moniker. In the rush to embrace tactical practice, both evaluation and ideology were overlooked.
The pamphlet's conclusion underscores just how indeterminate evaluation can be: "Short-term livability improvements demonstrate that improving the built environment is possible, and sometimes, [sic] only requires proactive policies and a little gumption. When executed well, such efforts help generate demand for even more substantial livability improvements." This is all fairly equivocal and highly qualified, with the emphasis on what's "possible," as long as you've got "gumption." And without ever explicitly referencing a New Urbanist agenda, its list of actions, too, seems carefully chosen to please a homogenous group of do-gooders. Ranging from the broad to the specific, these actions include Park(ing) Day, guerrilla gardening, food vendors, pop-up retail, and the Build a Better Block program. Systemic or political inner-city fixes, these are not. Build a Better Block, sponsored by Go Oak Cliff. [Image via Go Oak Cliff] Build a Better Block
, created in 2010 by Go Oak Cliff, a community organization in the Dallas neighborhood of Oak Cliff, leapfrogged quickly from grassroots action to municipal acceptance. The local success of its projects led to partnerships with Dallas' municipal economic development department and to small business incubators, as seen in their Living Plaza
project, a charrette-like event held in the Dallas City Hall plaza. The group offers a how-to guide
for cheaply and temporarily transforming an underused street into a vibrant scene. The tutorial demystifies the process: "Identify a location with a block of buildings that has a good pedestrian form, but lacks a complete street. Typically pre-war built areas, or former streetcar intersections." And: "Assemble team of grassroots community activists, artists, and DIY'ers. If possible, work with existing area non-profit leaders or organizers (Community Gardens groups, local volunteer corps, etc.)." And finally: "Invite your Mayor, council members, city staff, so they can see the possibilities for themselves. Be sure to track sales to show the increase in area business (potential for increased tax revenue is a city's largest motivator for change), and spotlight how traffic slows but people still have easy access and come out."
Founded in 2003, NextGen
functions, according to its manifesto
, as training for future CNU leadership. Here the question of evaluation becomes not just practical but also political: How to evaluate Tactical Urbanism
, given the relationship between its authors and an ideological organization often criticized for promoting greenfield development and neo-traditionalist values? Is this a case of an aging organization co-opting the progressive tendencies of a younger generation? Or does it point to a generational shift within the CNU, a refocusing from suburban to urban concerns, including such lifestyle elements as art walks, farmers markets, bike lanes, etc. Or maybe we just accept the definition of tactical urbanism offered in the NextGen booklet: "The development of social capital between citizens and the building of organizational capacity between public-private institutions, non-profits, and their constituents." Perhaps this linkage between public and private begins to stake out one criterion for evaluation? As such, some might call it good business; but a crusty punk might call it a sellout.
The New York-based Project for Public Spaces
has also taken up the matter of tactics; in an article on its website
, the place-making non-profit has rebranded DIY urbanism as "Lighter, Quicker, Cheaper: A Low-Cost, High-Impact Approach."  Like NextGen and numerous other organizations that are exploring interventionist approaches, PPS see the city as a laboratory for experimentation. One of the instructive bullet points in their article underscores why larger planning organizations are drawn to tactical practice, or "LQC": "Encourage an iterative approach and an opportunity to experiment, assess, and evolve a community’s vision before launching into major construction and a long term process." In other words, the early risks are shouldered by practitioners on the ground; more conventional planning practices then benefit from the lessons learned. As PPS puts it: "Leaders know they have to be able to react more quickly to a city’s diverse population and changing conditions than ever before. And that requires resiliency: adaptability, agility, the means to repair damage and remake derelict spaces of every scale. This can't come from the top down — it has to emerge incrementally, and it has to be driven by the people who know what they need." Top: Dekalb Market, Brooklyn.

But despite all the efforts to codify activism, there is still no handbook for assessment. In many cases tactical needs are implicitly tied to lifestyle values. This August, for example, Urban Space Management, a UK-based investment and development consultancy specializing in the "economic renewal of under utilised space for retail, workshop and community uses," opened the Dekalb Market
in Downtown Brooklyn, a few blocks from the Fulton Street Mall
. USM, which has friendly ties to PPS, has long relied on festival marketplaces to generate revitalization. For the Brooklyn project (a joint venture with Youngwoo & Associates), Urban Space has repurposed old shipping containers as market stalls. Here "Makers, Artists, Farmers and Chefs" (to quote the website) sell local products and produce; which means, in effect, that the Dekalb Market offers a finely curated selection to the urban bourgeois-bohemian — it's part locavore, part conscientious consumption, part community connection. Although connection to the community seems to be the weakest part, consisting merely of soul food cooking demonstrations, urban farming workshops and local DJ's programming music for the afternoon. Ultimately the whole effort seems geared for the weekend warrior — a self-aware consumer more interested in artisanal pickles and micro-brews than in the holistic economy that would sustain the existing community.
Although superficially similar in focus to Urban Space Management, the younger Renew Newcastle
, a non-profit based in a former steel town on the east coast of Australia, is different in instructive ways. Founded by Marcus Westbury in 2008, Renew Newcastle is an example of how an entrepreneur's dream and sweat equity can lay the groundwork for longer-term development. Initially financed on Westbury's credit card, the organization uses vacant buildings in Newcastle's central business district to incubate small businesses and local artists. More recently working with local, state and federal support and with the backing of the University of Newcastle and local businesses, Renew Newcastle collaborates with property owners to activate abandoned storefronts, with the goal of bringing new creative capital to the decaying downtown.
Westbury calls the organization a "permanent structure for temporary things." Not a design project per se, Renew Newcastle is instead a reinvention of the legal framework surrounding vacant buildings. It works to mitigate risk and reduce landlord liability; entrepreneurs occupy spaces on a rolling 30-day basis, and property owners are allowed to give tenants notice if a commercial opportunity becomes available. In this way the organization enables the collaboration and growth of small Etsy-type producers, artists and community groups. It's a demographic that resembles that of the Dekalb Market, but in Westbury's project participation is based more on entrepreneurial drive, less on hipster taste-making. And Renew Newcastle is supported by a robust social networking community, encouraged by free Wi-Fi. In this activist model, culture arises from the bottom up, but it has the capacity to instigate larger redevelopment and reinvestment.
In 2010, Newcastle was placed on Lonely Planet
's list of Top Ten Cities — a coup for a rustbelt town refueled by DIY energy. Still, the accolade — which kindled new media recognition, tourism and commercial development — underscores just how difficult it is to judge, rank and in general establish criteria for individual interventionist successes. It's frustrating that at this point the best we might be able to do is to be self-reflective, aware of the ideologies and contexts and contradictions of diverse projects. And we need to evaluate failure as much as success — to face the fact that some interventionist actions might fail, fall short or reveal themselves to be shallow, ugly or expensive. As it stands, evaluation is neither neutral nor systematic, but inevitably subjective and complicated. If we apply Westbury's model of a "permanent structure for temporary things" to the question of assessment, we'll see that what's been missing from our toolkit is a punchlist for best practices. The real success for DIY urbanism will be based not on any one project; it'll happen when we can evaluate the movement based on outreach, economic impact, community empowerment, entrepreneurship, sustainability and design. We're not quite there yet.
