Sarah Schindler (Maine) has posted Banning Lawns, forthcoming in the George Washington Law Review (2014). The abstract:
Recognizing their role in sustainability efforts, many local governments are enacting climate change plans, mandatory green building ordinances, and sustainable procurement policies. But thus far, local governments have largely ignored one of the most pervasive threats to sustainability — lawns. This Article examines the trend toward sustainability mandates by considering the implications of a ban on lawns, the single largest irrigated crop in the United States.
Green yards are deeply seated in the American ethos of the sanctity of the single-family home. However, this psychological attachment to lawns results in significant environmental harms: conventional turfgrass is a non-native monocrop that contributes to a loss of biodiversity and typically requires vast amounts of water, pesticides, and gas-powered mowing.
In this Article, I consider municipal authority to ban or substantially limit pre-existing lawns and mandate their replacement with native plantings or productive fruit- or vegetable-bearing plants. Although this proposal would no doubt prove politically contentious, local governments — especially those in drought-prone areas — might be forced to consider such a mandate in the future. Furthering this practical reality, I address the legitimate zoning, police power, and nuisance rationales for the passage of lawn bans, as well as the likely challenges they would face. I also consider more nuanced regulatory approaches that a municipality could use to limit lawns and their attendant environmental harms, including norm change, market-based mechanisms such as progressive block pricing for water, and incentivizing the removal of lawns.
Prof. Schindler has been working on this project and presented it at ALPS previously-- it will serve as a foundational article on the debate that is going to happen (whether or not you knew it) on the future of the American Lawn!

Edward J. Sullivan (Portland State) and Benjamin H. Clark (Independent) have posted A Timely, Orderly, and Efficient Arrangement of Public Facilities and Services--The Oregon Approach, 49 Willamette Law Review 411 (2013). The abstract:
The provision of public facilities and services is not an exciting planning topic because it deals with the details of supply, rather than the grander issues of economics, social equity and policy. Yet these details occupy an inordinate amount of time and attention by planners, elected officials, and other policy-makers, and account for a substantial share of unresolved issues in planning law.
This Article sets out the rise of infrastructure planning policy in Oregon under a statewide land use planning system that began in 1973.1 In Part I, we give a brief history and description of the structure of that system, followed by a discussion of the evolution of state infrastructure policy under Statewide Planning Goal 11, Public Facilities and Services, and its implementing rules. Following this background, this Article will examine the application of that policy, particularly with respect to the mechanics (Part II) and financing (Part III) of infrastructure planning and its role in the reinforcement of the separation of urban and rural uses (Part IV).
Oregon is one of the leading examples of the comprehensive approach to land use regulation, and any study of the state's approach--particularly one from lawyers who have been involved in the issues--will be a valuable additon to the literature in the field.
Pamela Ko (Sage Colleges) and Patricia Salkin (Touro College) have posted What Every Land Use Lawyer Should Know About the Emerging Use of Health Impact Assessment and Land Use Decision Making, New York Zoning and Planning Law Report, Vol. 16 No. 6 (May/June 2013). The abstract:
The field of Health Impact Assessment is relatively new to the United States, but already a number of state and local governments are incorporating these assessments into land use planning and decision making. In five years, the use of HIA in the U.S. has increased dramatically with more than 100 HIAs completed or in progress in the U.S. from 2007 to 2010. This article provides a brief overview of HIA in the United States, describes how it is being used in other states with respect to land use decision making, and examines how HIA is starting to be incorporated into traditional land use and environmental decision making in New York.
Add public health to the list that makes land use one of the most interdisciplinary fields of legal practice.

William A. Fischel (Dartmouth-Economics; Lincoln Institute of Land Policy) has posted Fiscal Zoning and Economists' Views of the Property Tax. The abstract:
Fiscal zoning is the practice of using local land-use regulation to preserve and possibly enhance the local property tax base. Economists agree that if localities can conduct "perfect zoning," which effectively makes all real estate development decisions subject to a review that balances its benefits and costs to the community, then the local property tax can be converted into a benefit tax and lacks the deadweight loss of taxation. This essay argues that American zoning is closer to this ideal than many other economists think. The practice is often difficult to detect because zoning serves several objectives besides fiscal prudence.
Anything by Fischel is a must-read!

Margaret F. Brinig (Notre Dame) and Nicole Stelle Garnett (Notre Dame) have posted A Room of One's Own? Accessory Dwelling Unit Reforms and Local Parochialism, forthcoming in The Urban Lawyer (2013). The abstract:
Over the past decade, a number of state and local governments have amended land use regulations to permit the accessory dwelling units (“ADUs”) on single-family lots. Measured by raw numbers of reforms, the campaign to secure legal reforms permitting ADUs appears to be a tremendous success. The question remains, however, whether these reforms overcome the well-documented land-use parochialism that has, for decades, represented a primary obstacle to increasing the supply of affordable housing. In order to understand more about their actual effects, this Article examines ADU reforms in a context which ought to predict a minimal level of local parochialism. In 2002, California enacted state-wide legislation mandating that local governments either amend their zoning laws to permit ADUs in single-family zones or accept the imposition of a state-dictated regulatory regime. We carefully examined the zoning law of all California cities with populations over 50,000 people (150 total cities) to determine how local governments actually implemented ADU reforms “on the ground” after the state legislation was enacted. Our analysis suggests that the seeming success story masks hidden local regulatory barriers. Local governments have responded to local political pressures by delaying the enactment of ADU legislation (and, in a few cases, simply refusing to do so despite the state mandate), imposing burdensome procedural requirements that are contrary to the spirit, if not the letter, of the state-law requirement that ADUs be permitted “as of right,” requiring multiple off-street parking spaces, and imposing substantive and procedural design requirements. Taken together, these details likely dramatically suppress the value of ADUs as a means of increasing affordable housing.
This looks really interesting. Here in Houston we have a significant number of ADUs--so-called "granny flats" because--stop me if you've heard this before--Houston has no zoning to make it illegal, as this article shows it has been in single-family residentail neighborhoods around the country. These ADUs provide an important supply of affordable "inside-the-Loop" (i.e. central city area) housing.

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.

Lee Fennell (Chicago) has posted Crowdsourcing Land Use, 78 Brook. L. Rev. ___ (forthcoming 2013). In it she looks ahead to the possibilities for emerging information technology to provide platforms for sharing data about land use impacts and preferences as well as landowner intentions. The last of these involves a proposal for the creation of publicly facilitated options markets in land use rights, an idea she previously outlined in her 2011 piece Property and Precaution (Journal of Tort Law, 2011). Here's the abstract for the Crowdsourcing article:
Land use conflicts arise from information shortfalls, and avoiding them requires obtaining and using information. Yet traditional forms of land use control operate in relative ignorance about landowner intentions, about preferences for patterns of land use that do not presently exist, and, more fundamentally, about land use impacts as they are experienced on the ground. Because information is expensive to gather and use, this ignorance may be rational. New technological and theoretical advances, however, offer powerful ways to harness and deploy information that lies dispersed in the hands of the public. In this symposium essay, I assess the prospects for an increased role for crowdsourcing in managing land use, as well as the limits on this approach. Governments must do more than elicit, aggregate, coordinate, and channel the preferences, intentions, and experiences of current and potential land users; they must also set normative side constraints, manage agendas, and construct appropriately scaled platforms for compiling and using information.

Greetings from George Washington Law School where the 2013 J.B. and Maurice C. Shapiro Conference is wrapping up. Entitled Laying the Foundation for a Sustainable Energy Future: Legal and Policy Challenges, there has been an impressive array of panelists from industry, governements, NGOs, and academia.
My co-athour Amy Morris (of Aspen Environmental Group) and I presented some of our work on the land use tradeoffs involved in renewable energy projects. We have been looking at these issues through the lens of solar projects in California, but the issues come up in many contexts. To give you some broad strokes of the project: In California, we see development of main types of projects--utility scale and distrbuted generation. The large utility-scale solar facilities in the California desert have been under heavy scrutiny and criticized for their potential impacts on environmental and cultural values. In an effort to avoid pristine desert ecosystems, agencies and environmental groups have been championed the use of distrubed lands. Such lands are not completely controversy-free either. As a threshold question, we have to figure out what lands should qualify as "distrurbed." In some cases, it may be that we are too quick to label something as disturbed. Generally though the big categories are brownfields, former landfills and mines, hardscapes (parking lots and rooftops), and marginal agricultural lands. I won't get into here, but trust me each of those categories has a host of issues surrounding its use.
I've been feeling a little out of my league as the land use lawyer in the midst of the energy experts but have learned a lot and have been impressed with GW's organization of the conference. I also really enjoy attending conferences in Washington DC where the audience is always filled with a great mix of people from agencies and nonprofits.

Michael N. Widener (Phoenix) has posted Moderating Citizen 'Visioning' in Town Comprehensive Planning: Deliberative Dialog Processes, forthcoming in the Wayne Law Review. The abstract:
This article describes opportunities in Comprehensive Plan (aka General Plan or Master Plan) initial adoption or subsequent amendment processes where stakeholders provide inputs on behalf of a diverse citizens community. The moderation process described here involves the City of Scottsdale, Arizona, currently engaged in developing its 2014 Plan which seeks to extend the city’s planning vision through 2045. Part II of this article provides a brief primer of a General Plan’s role in municipal police power exercise. Parts III and IV describe the history of the Scottsdale experience in amending its General Plan with citizen aid and rebellion. Part V delivers some observations about a citizen input method into planning matters that is subject to popular critique. Part VI summarizes the purpose of citizen inputs into a comprehensive plan, and how professional moderation of the stakeholders' inputs may appropriately channel public contributions to a municipality's land use vision without distortion or corruption of the process.

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.

A new article in Landscape and Urban Planning demonstrates that tourism can play a strong role in shaping landscape, indeed more so than local residents might realize. What I find interesting about the study is that it also shows conversion of land from agriculture to tourism resulting in an increase in economic benefit and ecosystem services. It may be hard to apply these findings outside of the Italian Island where the research was conducted, but the lessons about perceptions and planning models extend elsewhere.
Roberta Aretano, Irene Petrosillo, Nicola Zaccarelli, Teodoro Semeraro, Giovanni Zurlini, People Perception of Landscape Change Effects on Ecosystem Services in Small Mediterranean Islands: A Combination of Subjective and Objective Assessments, 112 Landscape and Urban Planning 63 (2013).
ABSTRACT: Humans constantly modify their environment to better fit their needs. These changes are even more important in small Mediterranean islands, where the flow and type of ecosystem services (ES) is constrained by insularity and heavily exploited by economic activities. We evaluated the dynamics of ES from 1954 to 2007 linked to the changes of the landscape of the Vulcano Island (southern Italy) and related such transformation to the perception of the local communities. We estimated the changes in the total economic value of ES and we coupled this objective assessment with a survey among inhabitants to measure the perception of driving forces and ES. The results show that agriculture was replaced by tourism, which simultaneously has profoundly affected the landscape and brought economic benefits to local population. Despite the urban-sprawl related to tourism development there is an increase of the flow of ES over time because of the conversion of some land-cover classes into others that provide a greater amount of ES. Local communities are aware of landscape and ES dynamics, but they do not perceive tourism as a driving force, which affects the natural attractiveness and cultural identity of their island. This approach integrates a commonly accepted objective technique to assign value to ES, with a subjective assessment taking into account how local people value the flow of ES. Effective strategies for ES management and governance need to address and incorporate local population expectations so to empower local stakeholders in the achievement of higher level of quality of life.

Here's a story out of Arizona, where apparently a historic Frank Lloyd Wright house was under dispute. From the New York Times story by Fernanda Santos and Michael Kimmelman:
The conservancy and other organizations petitioned the city in June to consider giving the house landmark status, after they learned of the former owners’ plans to split the lot to build the new homes. Three local government bodies approved the landmark designation, but the Council, which has the final say, postponed its vote twice, in part to give the parties more time to strike some type of compromise. There was also uncertainty over how some of its members would vote, given the homeowners’ lack of consent for the landmark process.
“If ever there was a case to balance private property rights versus the public good, to save something historically important to the cultural legacy of the city, this was it,” Larry Woodin, the president of the conservancy, said in an interview.
Seems like a good result here, while communities across the nation continue to struggle with how to strike that balance.

Christopher J. Tyson (LSU) has posted Localism and Involuntary Annexation: Reconsidering
Approaches to New Regionalism, published in the Tulane Law Review, Vol. 87 (2012). The abstract:
"Involuntary" annexation - the ability of cities to expand their territory unilaterally by extending their boundaries - is one of the most controversial devices in land use law. It is under attack in virtually every state where it exists. Involuntary annexation is a direct threat to "localism," the belief in small,
autonomous units of government as the optimum forum for expressing democratic freedom, fostering community, and organizing local government. Localism has been justifiably faulted with spurring metropolitan fragmentation and the attendant challenges it creates for regional governance. This critique is at the center of "New Regionalism," a movement of scholars and policy makers focused on promoting regional governance structures that respect the cultural draw of localism while correcting for its deficiencies. New Regionalism emphasizes bottom-up, voluntary governance structures and dismisses approaches like involuntary annexation as politically infeasible. Both types of approaches face considerable political challenges, but there are arguably more examples of well-functioning involuntary annexation regimes than there are successful models of New Regionalism. While involuntary annexation has been critical to the success of metropolitan regions in Texas and North Carolina, many regard it as a violation of the liberty and freedom that comes with property rights. Property rights are rooted in instinctive and culturally reinforced notions of personal identity and the inviolability of ownership. Localism extends this logic to municipal identity. The hostility toward involuntary annexation, therefore, can be understood as a response to the taking of a person's perceived right to express individual identity, group identity, status, and ownership through municipal identity. This notion of municipal identity as property threatens to undermine both existing involuntary annexation regimes as well as future New Regionalist proposals. While New Regionalism has well-reasoned justifications for focusing on more-voluntary, bottom-up governance structures, involuntary annexation remains a potent tool for facilitating regional governance and is worthy of defense and preservation.

Tony Arnold (Louisville) sends word that he has co-authored a chapter with Lance Gunderson (Emory--Environmental Studies) called Adaptive Law, forthcoming in the book Resilience and Law, Craig R. Allen & Ahjond S. Garmestani, eds., Columbia University Press, 2013. The abstract:
This book chapter proposes a bold sweeping set of characteristics of "adaptive law": features of the legal system that promote the resilience and adaptive capacity of both social systems and ecosystems. Law, particularly U.S. law, has been characterized as ill-suited to management of natural resources and the environment for resilience and sustainability. The maladaptive features of U.S. law include narrow systemic goals, mononcentric, unimodal, and fragmented structure, inflexible methods, and rational, linear, legal-centralist processes. This book chapter proposes four fundamental features of an adaptive legal system: 1) multiplicty of articulated goals; 2) polycentric, multimodal, and integrationist structure; 3) adaptive methods based on standards, flexibility, discretion, and regard for context; and 4) iterative legal-pluralist proceses with feedback loops and accountability. It then discusses these four features in the context of several socio-ecological issues and identifies needs for future study and development of adaptive law, particularly in light of panarchy theory about how complex, adaptive, interconnected systems change over time.
As many land use lawyers already know, Prof. Arnold is one of the leading scholars in establishing the emerging area of adaptive law; this collaboration with Prof. Gunderson looks to be a very helpful starting point for comparing ecosystems and social systems with respect to adaptation to changing circumstances.

Keith H. Hirokawa (Albany) and Jonathan D. Rosenbloom (Drake) have posted Land Use Planning in a Climate Change Context, forthcoming in RESEARCH HANDBOOK ON CLIMATE ADAPTATION LAW, Jonathan Verschuuren, ed., 2013. The abstract:
Although local governance is an experiment in adaptation (and often lauded for being so), climate change is distinct from traditional challenges to local governance. Nonetheless, many local governments are directing agencies to utilize existing and traditional local government tools to adapt to climate change. Local governments, for example, are adopting regulatory rules that require consideration of potential climate impacts in public-sector decisions with the goal of improving local adaptive capacity. Throughout these efforts, it is becoming clear that one of the most effective adaptation tools used by local governments is the power to plan communities. Through land use planning, local governments can increase resiliency to major climate shifts and ensure that our communities are equipped with built-in mechanisms to face and mitigate such changes. This essay identifies some of the most innovative planning tools available to local governments that illustrate the potential to plan for community resiliency. The essay begins by identifying some of the severe impacts local governments will experience from climate change. This part recognizes that not all local governments will experience climate change impacts the same, and that climate change adaptation is contextual. Part II provides an overview and inventory of traditional local governance tools, paying particular attention to zoning and nuisance laws. Part III looks more closely at specific structural tools that form the basic foundation for a wide variety of land use planning adaptation approaches and goals. The final part expands on the structural tools and explores specific mechanisms that can help local governments achieve adaptation goals and avoid catastrophic unpreparedness through proper land use planning in the climate change arena.
This piece, by two productive scholars who are also friends of this blog (Jonathan served as a guest blogger as well), should serve as a terrific introduction to the intersection of land use and climate change. The volume looks like good reading for students, scholars, and practitioners.

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!

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.

I've been stumbling across a lot studies lately about the links (or lack thereof) between vegetation and crime.I remember back in grad school when I was studying Landscape Architecture, we would meet with communities to discuss what types of parks and resources they would most like to see. The folks in the Fruitvale Neighborhood in Oakland repeatedly told us that they didn't want creeks or trees because these bred crime. Although there was no evidence to support this assertion, several people living in the area balked when we suggested opening up a waterway and adding greenspace.
Another study has come out examining the link between vegetation and crime. A study of Philadelphia indicated that where there are lots of trees, we see lower rates of assaults, robbery, and burglary. Theft, however, was not lower. Interesting to figure out how the perception of crime and statistics play out. (Personally, when I have been robbed the culprits have tended to hide behind cars, not trees). It is educational to juxtapose these crime studies with other work generally linking lower vegetation with lower income neighborhoods.
More on that Philadelphia Study:
"Does Vegetation Encourage or Suppress Urban Crime? Evidence from Philadelphia, PA" by Mary K. Wolfe and Jeremy Mennis in Landscape and Urban Planning (20 Sept. 2012).
ABSTRACT: There is longstanding belief that vegetation encourages crime as it can conceal criminal activity. Other studies, however, have shown that urban residential areas with well-maintained vegetation experience lower rates of certain crime types due to increased surveillance in vegetated spaces as well as the therapeutic effects ascribed to vegetated landscapes. The present research analyzes the association of vegetation with crime in a case study of Philadelphia, Pennsylvania. We examine rates of assaults, robberies, burglaries, and thefts in relation to remotely sensed vegetation abundance at the Census tract level. We employ choropleth mapping, correlation, ordinary least squares regression, and spatial econometric modeling to examine the influence of vegetation on various crime types while controlling for tract-level socioeconomic indicators. Results indicate that vegetation abundance is significantly associated with lower rates of assault, robbery, and burglary, but not theft. This research has implications for urban planning policy, especially as cities are moving towards ‘green’ growth plans and must look to incorporate sustainable methods of crime prevention into city planning.

Keith Hirokawa (Albany) has posted his latest interesting piece, Urban Forests as Green Infrastructure, a chapter from his book with Patricia Salkin GREENING LOCAL GOVERNMENT: LEGAL STRATEGIES FOR PROMOTING SUSTAINABILITY, EFFICIENCY, AND FISCAL SAVINGS, p. 257, Keith H. Hirokawa and Patricia Salkin, eds., American Bar Association, 2012. The abstract:
Urban forests capture air and water pollutants as they provide shade, habitat, and social value. The health and character of urban forests are determined by the priorities that communities place on them, the local regulations that direct land use choices, and the extent to which local governments address resource shortages through zoning, resource planning, and resource regulation. Local governments can plan and regulate urban forests to benefit (economically, socially, and environmentally) from the services that trees can provide to communities. This essay explores the role of urban forests in the local provision of local green infrastructure and the ways that local governments capture of the benefits of urban forests by planning and implementing tree protections.

Kathleen Oppenheimer Berkey (Pavese Law Firm) and Todd BenDor (Planning--North Carolina/MIT) have posted A Comprehensive Solution to the Biofouling Problem for the Endangered Florida Manatee and Other Species, Environmental Law, Vol. 42, No. 2, 2012. The abstract:
Biofouling is the undesirable accumulation of microorganisms, plants, algae, arthropods, or mollusks on a surface, such as a ship’s hull, when it is in contact with water for a period of time. Biofouling and its traditional remedies pose serious environmental consequences, including 1) the transportation of nonindigenous aquatic species that can outcompete native species for space and resources, thereby reducing biodiversity and threatening the viability of fisheries or aquaculture, 2) the harmful accumulation of zinc- or copper-based toxins, and 3) the increase in weight, decrease in flexibility and mobility, and topical damage of marine mammals hosting biofouling organisms. There are a number of existing legal mechanisms that address biofouling under international law. However, due to the complexity of biofouling, this Article posits that existing mechanisms are inadequate for comprehensively regulating the problem, leaving aquatic species susceptible to numerous negative effects from biofouling. To address these inadequacies, we recommend biofouling also be mitigated under the federal Endangered Species Act (ESA). First, we consider the Florida manatee (Trichechus manatus latirostris) as a case study species, and suggest that Florida’s Resource Conservation and Development (RC&D) areas develop a Safe Harbor umbrella agreement under section 10 of the ESA to create a new generation of ecological harbors that are safe from the dangers of biofouling. The agreement would include a Habitat Conservation Plan (HCP) that incorporates a combination of behavioral and infrastructural biofouling mitigation techniques to be applied regionally across estuary, freshwater, and saltwater ecosystems. Second, we suggest that both public and private owners of existing, proposed, and expanding marina developments be encouraged to voluntarily sign Safe Harbor Agreements under the RC&D areas’ umbrella agreement to avoid owners having to navigate the long and strenuous process of obtaining individual HCPs. The comprehensive biofouling management strategy proposed as a model here would require RC&D areas to carry out a range of biofouling best management practices that would protect species and the habitats on which they depend from the adverse effects of biofouling.
