Funds for historic preservation programs, particularly those dealing with identifying, cataloguing, and managing historic resources, are typically slashed when the economy sputters. Right now is such a time. In my previous post, I discussed ARCHES--a free, online, user-friendly, open-source geospatial software system developed by the Getty Conservation Institute and the World Monuments Fund that is purpose-built to inventory and manage immovable heritage to internationally adopted standards. Anyone can downloand and customize ARCHES to suit their needs.
Today I want to discuss a powerful, innovative but cheap technological tool that can aid authorities in their quest to create and/or update their historic resources digital inventory: online crowdsourcing. Simply put, online crowdsourcing allows someone to obtain needed services and/or content by soliciting voluntary contributions from the online public community rather than hiring employees or paying suppliers. Online crowdsourcing has been an extremely effective tool for preserving cultural heritage in many countries. For instance, the National Library of Finland is using online crowdsourcing to index its scanned archives. Similarly, the University of Cape Town in South Africa is using online crowdsourcing to transcribe collections containing the Bushman’s language, stories, and way of life. The National Geographic Society is using online crowdsourcing to analyze millions of satellite images of Mongolia showing potential archaeological sites in the hopes of discovering the tombs of Genghis Khan and his descendants. And an English non-profit organization has utilized online crowdsourcing and online crowdfunding—funds donated by the interested public online—to provide both finances and labor for an expert-led excavation of a Bronze Age causeway composed of millions of timbers in the Cambridgeshire fens. And perhaps most relevant to experiences of local governments in the United States, the City of Los Angeles has created a website, MyHistoricLA.org, that allows citizens to map and submit information about places of cultural importance to them which may not be architecturally significant (and thus escape the purview of preservation officials).
Drawing on the crowdsourcing experience of others, local governments and cities in the United States could create an online portal attached to their own digital inventories, or create an appended website like MyHistoricLA. This portal or website could offer training modules to citizens on cultural heritage recording practices and afterwards ask them to collect and upload descriptive information, statistics, pictures, videos, and maps on historic resources in their neighborhoods. The information uploaded to this portal could be screened and vetted by authorities before permanently adding it to the digital repository, ensuring quality control. In this way, local governments and cities could gather and preserve vast amounts of data related to their cultural heritage in a short period of time and at minimal cost. Furthermore, such a strategy also fosters civic pride, a sense of community, and a deeper, more tangible connection to the city’s past, particularly for younger generations who are adept at using technology. It also offers peace of mind knowing that if and when a disaster occurs that as much cultural heritage as possible has been preserved for future generations.

Posting from New Orleans (No. 2) -- Reviving Inner-City Neighborhoods: the Challenges of Teaching and Doing Urban Revitalization Work
This is the second in a series of posts from New Orleans. The first appeared last Monday, August 4th. As I promised in that first piece, today we’re just beginning to take a walk down one of New Orleans’ historic commercial corridors, Oretha Castle Haley Boulevard (O.C. Haley Blvd.), which is named after a leading local civil rights activist. Today’s post looks at the fortuitous intersection between post-Katrina federally-funded long-term recovery programs and the extensive pre-storm efforts of O.C. Haley Boulevard activists and stakeholders to reclaim this historic corridor.
Photo (2014): O.C. Haley Boulevard looking northwest toward the Central Business District (CBD)
In the decades leading up to the 1960s, O.C. Haley Boulevard (formerly known as Dryades Street) was one of the principal shopping destinations for black families and also a pre-Civil Rights Era hub for the City’s best black musicians. During the 50 years since the mid-1960s, O.C. Haley withered a little more each passing year. First, the corridor lost in increasing numbers its shoppers; then its businesses began to close; and then families in surrounding blocks began to move away. Finally, in the years leading up to Hurricane Katrina, the Boulevard started losing its architecturally distinguished commercial structures – one by one.
Earlier this spring, in his CityLab article, The Overwhelming Persistence of Neighborhood Poverty, Richard Florida tacitly suggests that O.C. Haley’s fate has been the fate of our oldest urban neighborhoods all across the country. Florida’s article, citing a May 2014 study by Joseph Cortright and Dillon Mahmoudi, disclosed a number of fascinating tidbits about cities, but the statistic that really jumped out is this one: since 1970 “for every single gentrified [urban] neighborhood, 12 once-stable neighborhoods have slipped into concentrated disadvantage.”
That statistic about declining inner city neighborhoods stopped me in my tracks. As long as I can remember, I’ve been fascinated by two things: old inner city neighborhoods (my dad is a preservation architect) and the Red Sox (born and raised in Boston). This is to say that I'm easily captivated by box score style statistics, such as the one Florida cites. I'm also no stranger to extended periods of adversity for the teams I love. But I clearly did not have an accurate idea of the extent to which so many inner city neighborhoods had faced such long odds for so long a period of time.
The statistic Florida cites concerning the decline of inner city neighborhoods got me to thinking about what I taught my land use students last semester. If our land use, local government, real estate finance, and community and economic development clinic students aim to work in cities, Richard Florida is telling us that they have their work cut out for them. The data suggests there are many hundreds of O.C. Haley-like Boulevards across the country.
Of course the problem of distressed inner city communities is not new. As we all know, lawyers have for years played critical roles in representing community groups, developers, banks, philanthropic funders, and local government clients on every side of urban revitalization deals. But Florida’s article reminded me how large the challenge of neighborhood revitalization looms for cities. There’s a lot of ground to cover in a basic land use class, but I found myself asking what my students and I learned this past semester that would help them do this work better or smarter. The short answer is that we squeezed in as much time as we could to study the redevelopment ‘tool box’ a city and its neighborhood organizations can use to stabilize and revitalize neighborhoods: land trusts, land banks, eminent domain, code lien enforcement, tax credits, etc. But thinking about Florida’s article reminded me that this approach is missing a key element. After all, most of these stabilization and revitalization tools were available to young lawyers and planners and community groups for the better part of the 45-year period that Florida observes the rapid evaporation of inner-city neighborhood vitality.
In thinking about the statistics Florida discusses and about the long decline of O.C. Haley Boulevard, it struck me that the conversation that I didn’t have this spring with the land use students is about the nature of urban revitalization work. It is often a slog. Some describe the work as being as slow and painfully incremental as ‘trench warfare.’ I prefer how some describe it as caring for a patient recovering from a debilitating life-threatening injury. That is, urban revitalization work concerns much more than strategic deployment of those redevelopment “tools.” It goes far beyond helping your client close on tax credit financing for a major catalytic redevelopment project. Rather, it also depends on the patient persistence of a diverse team of ‘caregivers’ over a long period of time. Some of those ‘caregivers’ are internal to the community. They are the local merchants associations and neighborhood advocacy groups. They are also the local community development corporations, code enforcement staff, city councilpersons, assistant city attorneys, philanthropic foundation program officers, and the law school clinics with neighborhood organization clients. Neighborhood revitalization ordinarily requires keeping at least part of these diverse teams together for years – often more than a decade. In other words, it is worth discussing with our students that while they need to know the law and understand the nuances of the ‘tools’, the work of revitalizing a neighborhood is not usually just a transactional matter, but it is much more an organic process.
Kathy Laborde, is President and CEO of Gulf Coast Housing Partnership, one of Louisiana’s leading developers of commercial and residential projects serving low and moderate income communities. Beginning in the late 1990s as a community development banker, Laborde has worked with representatives of the O.C. Haley Boulevard neighborhood on redevelopment projects. Prior to Hurricane Katrina she also moved her development firm’s offices onto the Boulevard. Like the neighborhood merchants association and local community groups, Laborde knew O.C. Haley Boulevard had enormous potential to rebound – even as most New Orleanians ignored the corridor and consciously avoided it for fear of encountering the crime for which the Boulevard had become known. Together with a strong and cohesive band of neighborhood advocates, she has long been a steadfast proponent of revitalizing the Boulevard. In a meeting in her office earlier this month, I asked her why, in the late 1990s, she and neighborhood leaders believed that they could turn around the Boulevard’s fortunes.
In the next blog post, we look at snapshots of the Boulevard's challenging 15 year journey through and beyond Hurricane Katrina to an active neighborhood renaissance that continues to catch the attention of both the city's visitors and long-time residents.

As this is my maiden voyage into the blogosphere, I thought I’d share with you my passion for historic resources and their preservation along with an exciting recent publication. Before ever dreaming of law, or legal academia for that matter, I was studying medieval British history at Oxford University. Due to many experiences in the UK—handling and reading thousand-year-old vellum documents on a regular basis; participating in voluntary archaeological digs for Anglo-Saxon settlements; mapping the phases of urban growth in Oxford; charting extant Romanesque and Gothic survivals in old Oxford buildings and sharing these discoveries with others—I realized more fully how the past enriches the present, and how without an understanding of what has come before, our own lives are less complete.
I’ll never forget eating pizza on the second floor of an old restaurant in Oxford. While munching on a slice, I looked over at one of the walls. During renovations the owners discovered 16th century wall paintings depicting the symbiotic relationship between plants and humans and took steps to preserve these paintings, incorporating them into the ambience of a modern pizza joint. This visible connection between the past and present made me muse about all the people who had eaten (or lived) in this building before, and it made mediocre pizza taste like manna.
Laws governing the management of tangible historic resources—often referred to as Historic Preservation Law and/or Cultural Heritage Law—are rounding into maturity. Given that historic resources encompass many types of law (property law, land use law, natural resources law, environmental law, Native American law) and traverse local, state, tribal, federal and international jurisdictions, there has long been a need for a resource that speaks to those jurisdictions and varied types of law collectively, rather than in silos as the field is typically analyzed
Professor Sara Bronin (University of Connecticut School of Law) and I have recently published such a resource with West Academic: Historic Preservation Law in a Nutshell.
Here is the publisher's blurb: “Historic Preservation Law in a Nutshell provides the first-ever in-depth summary of historic preservation law within its local, state, tribal, federal, and international contexts. Historic Preservation is a burgeoning area of law that includes aspects of property, land use, environmental, constitutional, cultural resources, international, and Native American law. This book covers the primary federal statutes, and many facets of state statutes, dealing with the protection and preservation of historic resources. It also includes key topics like the designation process, federal agency obligations, local regulation, takings and other constitutional concerns, and real estate development issues.”

I hope that this book can be of use to you, and I would welcome any feedback on how it may be improved in future editions.
To some extent, all legal and policy decisions we make today--particularly those concerned with land--are predicated on the past. And in knowing about and respecting the past, we learn more about ourselves. As Shakespeare wrote in the Tempest, "What's Past is Prologue".

Last week, Buffalo hosted the 22nd Congress for New Urbanism. With a constrained conference budget, I was planning on just scoping out the (numerous) public events. Then conference funding came through from a surprising source. I actually won free conference registration via Yelp! (yes it pays to be elite). I am not sure what it says about academia when we have to look to social media to help with our research funding but I was happy to get in the door!
CNU 22 was a mixture of the inspirational and the mundane. It was amazing to see people from all over the country (and particularly so many from Buffalo) coming together to think about how to improve your communities. I bathed in the local pride (feeling the Buffalove as we say around here) and heard inspiring tales about efforts in Toronto, Minneapolis, DC, and Milwaukee. But nothing was actually radical. In some ways this is an encouraging story. It no longer seems crazy to argue that suburban sprawl is destroying community. I really didn't need convincing that we should have more walkable or bikable cities. There seems to be general agreement on what elements make for a thriving urban environment and largely agreement from the attendees on how to get there (community involvement, form based codes, economic development). Thus, while I enjoyed myself and met some fascinating folks I left the conference with an empty notebook. Maybe I just attended the wrong sessions, but I wonder what types of legal changes we might need, what type of property tools we can use, and of course who is gonna fund it all. Any suggestions?

Sarah Schindler (Maine) has posted Unpermitted Urban Agriculture: Transgressive Actions, Changing Norms and the Local Food Movement, 2014 Wisc. L. Rev __ (forthcoming). Just in time for the finalizing of my presentation on unauthorized vacant property use for next month's ALPS conference (in Vancouver!). Here's the abstract:
It is becoming more common in many urban and suburban areas to see chickens in backyards, vegetable gardens growing on vacant, forclosed-upon, bank-owned property, and pop-up restaurants operating out of retail or industrial spaces. The common thread tying all of these actions together is that they are unauthorized; they are being undertaken in violation of existing laws, and often norms. In this essay, I explore ideas surrounding the overlap between food policy and land use law, and specifically the transgressive actions that people living in urban and suburban communities are undertaking in order to further their local food-related goals. I assert that while governmental and societal acceptance and normalization of currently illegal local food actions is likely needed for the broader goals of the local food movement to succeed, there are some limited benefits to the currently unauthorized nature of these activities. These include transgression serving as a catalyst for change and as an enticement to participate.

Here's an interesting sounding one!
Call For Participation : Comparative Urban Law Conference
June 30, 2014, London, England
The Fordham Urban Law Center is pleased to announce a call for participation for the Comparative Urban Law Conference, which will be held on Monday, June 30, 2014 at Loyola Hall, University of London. The Conference will gather legal and other scholars for a provocative, engaging conversation about the field of "urban law" from an international, comparative, and interdisciplinary perspective. The Conference will focus on the nature and boundaries of urban law as a discipline, which participants will explore through overlapping themes such as the structure of local authority and autonomy and the role of law in urban policy areas such as environmental sustainability, consumer protection, public health, housing, and criminal justice, among others. The goal is to facilitate an in-depth exploration across sub-specialties within the legal academy to help develop an understanding of urban law in the twenty-first century.
PAPER SUBMISSION PROCEDURE: Potential participants in panels and workshops throughout the day should submit a one-page proposal to Professor Nestor Davidson at firstname.lastname@example.org. If you are already working on a draft paper, please include that draft with your submission, but participants do not need to have prepared a formal paper to join the conversation. The deadline for topic proposal submissions is Thursday, February 13. We will discuss potential publishing options available as a result of conference participation. Please contact Annie Decker at email@example.com with any questions.
ABOUT THE URBAN LAW CENTER: The Urban Law Center at Fordham Law School in New York City is committed to understanding and affecting the legal system's place in contemporary urbanism. See: http://law.fordham.edu/urbanlawcenter.htm for more information about our activities.

Stephanie Maloney (Notre Dame Law Review) has posted her note entitled Putting Paradise in the Parking Lot: Using Zoning to Promote Urban Agriculture, 88 Notre Dame L. Rev. 101 (2013). Here's the abstract:
This Note explores municipal zoning regulations related to urban agriculture and evaluates specific zoning mechanisms that can be implemented to efficiently promote the accommodation of urban agriculture and access to locally grown food. Consideration of the benefits and costs of urban agriculture, alongside the zoning practices of leading cities, will assist in developing zoning laws that meet the needs of American cities and citizens. Part I of this Note introduces the concept and history of urban agriculture, providing an overview of its benefits and challenges. Part II examines municipal zoning and the principle zoning restrictions that impact farming and gardening in a city. Part III reviews the varied efforts of municipalities to support urban agriculture by incorporating it into local zoning codes. Part IV concludes by offering recommendations for the municipal integration of agriculture into the urban fabric, with particular attentiveness to participatory policy-making in the form of food policy councils.

Hannah Wiseman (Florida State) has posted Urban Energy, published in the Fordham Urban Law Journal, (invited symposium), 2013. The abstract:
The twenty-first century has seen important changes in the U.S. energy system, and most share a common theme: In some regions of the country, energy infrastructure is now located near human populations. As has always been the case; fuel in the form of oil, gas, sunlight, wind, water, or other energy sources must be extracted wherever it happens to be found; and humans have little control over its location. Energy companies must move to the areas of highest resource abundance and find available surface space from which to capture these fuels. Compounding this challenge is the fact that some of our most abundant remaining energy sources exist in low concentrations and are widely distributed. Sunlight and wind require thousands of acres of technology installations to be efficiently captured, and unconventional oil and gas resources exist at low densities over wide areas in shales or tight sandstone formations. As we tap these sources in ever more numerous locations, energy bumps up against certain human population centers. The city of Fort Worth, Texas, for example, now hosts thousands of natural gas wells, and San Diego has more than 4,500 solar projects. Indeed, with the rise of the Smart Grid; every American consumer could become a small source of electricity; sending electricity back into the grid from a plug-in hybrid vehicle, a solar panel or small wind turbine, a fuel cell, or battery storage. As the extraction of fuels and generation of electricity (“energy production”) become integral parts of certain population centers; the law will have to adjust; responding to land use and environmental disputes, nuisance claims, enhanced demands on local electricity grids, and concerns about equity, in terms of unevenly distributed effects. This Essay explores these new themes in energy law; investigating how certain populated areas have begun to embrace their role as energy centers; by addressing conflicts ex ante, creating systems for permitting and dispute resolution that balance flexibility with predictability, and managing the tradeoff between land-based energy demands and other needs. It also briefly proposes broader lessonsfor improving energy law, based on the piecemeal approaches so far.
Very important analysis; Prof. Wiseman (a former guest-blogger here!) has provided some of the most interesting recent scholarship on the new energy boom and land use.

This past weekend I was in Southern California for a family wedding, and we had the chance to go over to the Getty Museum. It is a spectacular place for many reasons including land use and architecture. Right now, and through July 21, the Getty is featuring an incredibly interesting exhibit called Overdrive: LA Constructs the Future, 1940-1990. It tells the story of how LA was the archetype for American land use and development in the postwar era through the end of the 20th Century.

I stumbled across a recent artcle in Applied Geography that I think may be of interest to our readers. I got even more excited when I realized the piece was from colleagues in SUNY Buffalo's Geography Department. Amy Frazier, Sharmistha Bagchi-Sen, and Jason Knight examine the effect of demolition on land-use patterns and changes in human-environment interactions.
While many cities are worried about smart growth and we land use profs spend a lot of time thinking about it, shrinking cities like Buffalo face another challenge: smart decline. The authors (and others) have convinced me that maintaining pro-growth policies in a shrinking city is ill-advised. Instead of thinking we're going to suddenly grow Buffalo, let's think about how we can grow smaller gracefully. Smart decline policies include things like land banks, urban farming, and green infrastructures.
Frazier et al. look at the smart decline policy of demolition. Earlier studies (as well as conventional wisdom) suggest that vacant buildings attract criminal activities (the broken window effect). This study examined a five-year demolition program in Buffalo to assess whether demolitions of vacant buildings actually lead to reduced crime. Their results are fascinating and like all of the best projects point out areas where more research is needed. The big take aways seem to be that there may be some local reductions in crime, but that likely means that the criminal activity is pushed elsewhere. This can have unanticipated impacts on surrounding areas, transportation needs, housing values etc. Such policies need to examine the way that demolitions will shift land uses and impact human-environment interactions. To do so in a successful way will necessarily include regional approaches.
Amy E. Frazier, Sharmistha Bagchi-Sen, & Jason Knight, The Spatio-temporal Impacts of Demolition Land Use Policy and Crime in a Shrinking City 41 Applied Geography 55 (2013)
ABSTRACT: Land use change, in the form of urbanization, is one of the most significant forms of global change, and most cities are experiencing a rapid increase in population and infrastructure growth. However, a subset of cities is experiencing a decline in population, which often manifests in the abandonment of residential structures. These vacant and abandoned structures pose a land use challenge to urban planners, and a key question has been how to manage these properties. Often times land use management of these structures takes the form of demolition, but the elimination of infrastructures and can have unknown and sometimes unintended effects on the human-environment interactions in urban areas. This paper examines the association between demolitions and crime, a human-environment interaction that is fostered by vacant and abandoned properties, through a comparative statistical analysis. A cluster analysis is performed to identify high and low hot spots of demolition and crime activity, specifically assault, drug arrests, and prostitution, over a 5-year period. Results show that there is an association between the area targeted for significant demolition activity and the migration of spatial patterns of certain crimes. The direction of crime movement toward the edges of the city limits and in the direction of the first ring suburbs highlights the importance of regional planning when implementing land use policies for smart decline in shrinking cities.

I got my registration brochure this past week for the AALS Midyear Meeting to be held in San Diego in early June. Along with two criminal justice programs, it features a Worskhop on Poverty, Immigration and Property that brings together a fascinating mix of presentations from scholars frequently referenced on your favorite land use law blog. Unfortunately, I won't be able to attend; but, I look forward to seeing the papers.
One panel that drew my eye features work from David Reiss (Brooklyn), Marc Poirier (Seton Hall) and Twila Perry (Rutgers-Newark). We have previously blogged about related work by David and Marc. Prof. Perry has written extensively about transracial adoption, but I was not familiar with her work prior to receiving the mailing. She will be presenting in June on Gentrification: Race, Class Law and the Integrationist Ideal. I came across an earlier work she published comparing gentrification and transracial adoption entitled Transracial Adoption and Gentrification: An Essay on Race, Power, Family, and Community, 26 B.C. Third World L.J. 25 (2006). Here's the abstract:
In this article, Professor Perry finds common ground between the two seemingly disparate contexts of transracial adoption and gentrification. Professor Perry argues that both transracial adoption and gentrification represent contexts in which, in the future, there may be increasing competition for limited resources. In the former case, the limited resource is the healthy Black newborn. In the latter, it is desirable, affordable housing in the centers of our cities. After explaining how a competition between Blacks and whites over Black newborns could arise, Professor Perry argues that in any such competition, Blacks will increasingly find themselves at a disadvantage stemming from the consequences of institutionalized racism. The article argues that there is a public discourse in both contexts that blames Blacks for the problems facing Black families and Black communities and valorizes whites who transracially adopt or move into inner-city neighborhoods undergoing gentrification. Professor Perry urges increased government involvement to preserve Black families and to protect Blacks against the displacement that often results from gentrification.

As part of a radio show on the recently declared Anthropocene (we're already 8000 years into it!), Big Picture Science featured an interview with Ed Glaeser (Harvard-Economics) about how city living moderates rather than aggravates global warming. The Glaeser interview begins 22 minutes into the show. Among other things, I learned that the entire population of the Earth could be housed on 1/10th-acre lots within the land area that makes up Texas. (I call the intersection down the block from Festa's house!)
In arguing for urbanization as a vital greening strategy (or at least an alternative to hunter-gatherer existence), Glaeser draws upon his book, Triumph of the CIty. Matt blogged about David Reiss's review of that book here.

For those of you who just cannot get enough of Richard Florida, the Daily Beast this week features an exchange between Joel Kotkin and Richard Florida on whether Florida's evolution as a proponent of cities being geared toward the "creative class" constitutes a full-scale retreat from his emphasis on this group as a generator of local and regional economic growth. Florida's installment references a related piece on the importance of urban design that promotes personal interaction that he published in the Wall Street Journal back in July.

John R. Nolon (Pace) has posted Shifting Paradigms Transform Environmental and Land Use Law: The Emergence of the Law of Sustainable Development, forthcoming in the Pace Environmental Law Review (2013). The abstract:
We began these two decades reacting to the market’s interest in developing greenfields and coastal property and end it wondering how to prepare more urbanized places for a growing population of smaller households who seek the amenities of urban living and some protection from the storms ahead. This essay discusses this and nine other fundamental paradigm shifts in environmental and economic conditions that are reshaping the law and changing the way state and local governments control land use and order human settlements.
Prof. Nolon has spearheaded the scholarly movement toward framing land use as an area of law that incorporates local government mechanisms and the imperatives of environmental regulation, which he has led into a broader conception of sustainability. This essay provides a great overview of how our communities depend on land use law.

James M. Anderson (RAND Corp.), John MacDonald (Penn--Criminology), Ricky Bluthenthal (Southern Cal--Medicine), and J. Scott Ashwood (RAND Corp.) have posted Reducing Crime by Shaping the Built Environment with Zoning: An Empirical Study of Los Angeles, 161 University of Pennsylvania Law Review 699 (2013). The abstract:
The idea of using law to change the built environment in ways that reduce opportunities to commit crimes has a long history. Unfortunately, this idea has received relatively little attention in the legal academy and only limited rigorous empirical scrutiny. In this Article, we review the considerable literature on the relationship between zoning, the built environment, and crime. We then report the results of two empirical studies on these relationships. First, we conducted a study of the effect of zoning on crime using 205 blocks selected in eight different relatively high crime neighborhoods in Los Angeles that have similar demographic character- istics but different forms of zoned land use. We find that mixed commercial- and residential-zoned areas are associated with lower crime than are commercial-only zoned areas. Second, we matched neighborhoods undergoing zoning changes between 2006 and 2010 with neighborhoods that underwent no zoning changes during this period but had similar preexisting crime trajectories between 1994 and 2005. The primary zoning change in these neighborhoods was to convert parcels to residential uses. We find that neighborhoods in which there was a zoning change experienced a significant decline in crime. Our results suggest that mixing residential-only zoning into commercial blocks may be a promising means of reducing crime.
Looks like a fascinating interdisciplinary collaboration.

Today I stumbled across this compelling Associated Press story about how urban advocates have very mixed feelings about how the Newtown shootings have seemingly changed the national debate around gun control.
The moment also is causing some to reflect on the sudden change of heart. Why now? Why weren't we moved to act by the killing of so many other children, albeit one by one, in urban areas?
Certainly, Newtown is a special case, 6- and 7-year-olds riddled with bullets inside the sanctuary of a classroom. Even in a nation rife with violence, where there have been three other mass slayings since July and millions enjoy virtual killing via video games, the nature of this tragedy is shocking.
But still: "There's a lot of talk now about we have to protect our children. We have to protect all of our children, not just the ones living in the suburbs," said Tammerlin Drummond, a columnist for the Oakland Tribune.
In her column Monday, Drummond wrote about 7-year-old Heaven Sutton of Chicago, who was standing next to her mother selling candy when she was killed in the crossfire of a gang shootout. Also in Chicago, which has been plagued by a recent spike in gun violence: 6-year-old Aaliyah Shell was caught in a drive-by while standing on her front porch; and 13-year-old Tyquan Tyler was killed when a someone in a car shot into a group of youths outside a party.
Food for thought.

Happy Halloween! If you're out trick-or-treating tonight, think about what planners call the "trick-or-treat test" for your neighborhood. The idea is that based on design and form, a great neighborhood for trick-or-treating--kids and families walking around the streets, visiting door to door--is also likely to be a great neighborhood year-round. City Planner Brent Toderian writes about this at the Huffington Post in Does Your Neighbourhood Pass the 'Trick or Treat Test'?:
Great neighbourhoods for trick-or-treating also tend to be great neighborhoods for families everyday:
- Tree-lined streets designed for walkers more than speeding cars.
- Enough density and community completeness, to activate what I call "the power of nearness" - everything you need, nearby.
- Good visual surveillance through doors and stoops, windows (and I don't mean windows in garages), porches and "eyes on the street."
- Connected, legible streets that let you "read" the neighbourhood easily -grids tend to be good for this, but other patterns work too.
All of these are great for trick-or-treating, and equally great for walkable, healthy, economically resilient communities year-round.
It makes a great deal of sense, though I hadn't previously known that the "trick-or-treat test" was a term of art in the planning community. Thanks to Jenna Munoz for the pointer. A related item is Richard Florida's 2012 Halloween Index at The Atlantic Cities:
For this year's "Halloween Index," Kevin Stolarick and my Martin Prosperity Institute (MPI) colleagues focused on five factors that make for a great Halloween metro area — population density (which makes for efficient trick-or-treating), kids ages five to 14 (as a share of metro population), and median income (a measure of regional affluence), as well as candy stores and costume rental stores per one hundred thousand people.
In the story at the link, you can check out the map which shows the best scoring cities in the categories; Chicago is #1. Zillow, however, has San Fransisco at #1 with its similar but slightly different methodology for determining the 20 Best Cities to Trick or Treat in 2012:
There is a common belief that wealthy neighborhoods are the Holy Grail for harvesting the most Halloween candy. However, to provide a more holistic approach to trick-or-treating, the Zillow Trick-or-Treat Index was calculated using four equally weighted data variables: Zillow Home Value Index, population density, Walk Score and local crime data from Relocation Essentials. Based on those variables, the Index represents cities that will provide the most candy, with the least walking and safety risks.
Finally, Paul Knight at Treehugger provides a mathematical forumula in More on the Trick or Treat Test: Calcluating the "Candy Density":
Potential Candy Score (Candy Pieces) = Target Neighborhood (Acres) x Houses-Per-Acre x Families-Per-House (accounting for duplexes, etc) x % Candy-Giving-Families x Candy-Pieces-Per-Family
I always say that land use is ultimately about the built environment of the communities in which we live. If you are out in your community on Halloween night, be safe, and take the opportunity to observe and think about land use!

In Places, a former graduate school colleague of mine has a fascinating essay on the use of public spaces. The essay is drawn from a chapter in the forthcoming book Beyond Zuccotti Park: The Freedom of Assembly and the Occupation of Public Space.
Hou provides examples of public transformation of places into sites of action, meaning and possibility. Challenging us to rethink our notion of “public” in public space. The essay is accompanied by photos of public appropriation and use of public spaces from across the globe.
For those of you unfamiliar with Places, it is an interdisciplinary journal on architecture, landscape, and urbanism. It has been an online journal since 2009, which is a superior format as it allows images and discussion of the articles. Check it out.

Resarchers from Arizona State have created a program that maps CO2 in cities. What is fascinating about this project is that they can map it down to the level of individual blocks and buildings. While this program is only currently focused on urban areas, global CO2 maps (and particularly maps of rural areas) could be pivotal in any programs related to carbon emissions. It could enable us to identify the heaviest producers and also perhaps assist in sequestration programs. They even made a cool video showing how it works. What a great tool for local governments.
Here is the citation and abstract:
Kevin R. Gurney, Igor Razlivanov, Yang Song, Yuyu Zhou, Bedrich Benes, & Michel Abdul-Massih, Quantification of Fossil Fuel CO2 Emissions on the Building/Street Scale for a Large U.S. City, Envtl Sci. & Tech. (August 15, 2012)
In order to advance the scientific understanding of carbon exchange with the land surface, build an effective carbon monitoring system, and contribute to quantitatively based U.S. climate change policy interests, fine spatial and temporal quantification of fossil fuel CO2 emissions, the primary greenhouse gas, is essential. Called the “Hestia Project”, this research effort is the first to use bottom-up methods to quantify all fossil fuel CO2 emissions down to the scale of individual buildings, road segments, and industrial/electricity production facilities on an hourly basis for an entire urban landscape. Here, we describe the methods used to quantify the on-site fossil fuel CO2 emissions across the city of Indianapolis, IN. This effort combines a series of data sets and simulation tools such as a building energy simulation model, traffic data, power production reporting, and local air pollution reporting. The system is general enough to be applied to any large U.S. city and holds tremendous potential as a key component of a carbon-monitoring system in addition to enabling efficient greenhouse gas mitigation and planning. We compare the natural gas component of our fossil fuel CO2 emissions estimate to consumption data provided by the local gas utility. At the zip code level, we achieve a bias-adjusted Pearson r correlation value of 0.92 (p < 0.001).

Robert C. Ellickson (Yale) has posted The Law and Economics of Street Layouts: How a Grid Pattern Benefits a Downtown, forthcoming in the Alabama Law Review from its lecture series on boundaries. The abstract:
People congregate in cities to improve their prospects for social and economic interactions. As Jane Jacobs recognized, the layout of streets in a city’s central business district can significantly affect individuals’ ability to obtain the agglomeration benefits that they seek. The costs and benefits of alternative street designs are capitalized into the value of abutting lots. A planner of a street layout, as a rule of thumb, should seek to maximize the market value of the private lots within the layout. By this criterion, the street grid characteristic of the downtowns of most U.S. cities is largely successful. Although a grid layout has aesthetic shortcomings, it helps those who frequent a downtown to orient themselves and move about. A grid also is conducive to the creation of rectangular lots, which are ideal for siting structures and minimizing disputes between abutting landowners. Major changes in street layouts, such as those accomplished by Baron Haussmann in Paris and Robert Moses in New York City, are unusual and typically occur in bursts. Surprisingly, the aftermath of a disaster that has destroyed much of a city is not a propitious occasion for the revamping of street locations.
Highly recommended, with lots of interesting planning-type details in addition to the larger importance to land use theories and approaches.
