Problem: Private approaches to urban service provision are becoming more popular. Some argue these approaches are more efficient and more democratic than government provision because they are voluntary. While these club approaches can shift the burden of infrastructure finance to direct groups of users, they can also fragment urban service delivery and justify unevenness in service quality across the city.

Purpose: This article explores examples of club goods, that is, common interest developments (CIDS) for housing, business improvement districts (BIDs) for commercial areas, and economic development zones (EDZs) for commercial and industrial areas, and assesses their implications for local government. Emphasis is given to how clubs internalize benefits to members of the club but shed externalities onto the broader local government system. A critical governance concern is the impact on the long-term ability of local government to coordinate across disparate elements and interests in the community.

Methods: I discuss three types of clubs ranging from totally private common interest developments (home owners associations), to partially private business improvement districts, to totally public economic development zones. These club types are analyzed in terms of economic benefits, externalities, governance structure, and broader concerns with equity and sustainability.

Results and conclusions: Club good approaches to urban infrastructure delivery enhance private investment and reduce costs to cities, but they also shed externalities onto the broader city. Although these clubs are often private associations, this article shows how they are critically supported by government, beyond the property rights requirement assumed by most theorists. A further concern is that club approaches may undermine support for equity and redistribution at the broader city level.

Takeaway for practice: Local governments are under pressure to provide public goods efficiently and engage private voluntary approaches whenever possible. The efficiency and popularity of club approaches derives in part from their ability to capture the benefits of increased investment for internal benefit. However, local government managers also must manage diversity and build public support for investment to ensure equity across the urban territory. Balancing the benefits of club goods with the need for broader urban integration is a key challenge for planners and urban managers.

Problem: Form-based codes (FBCs) affect the design of cities with rules about building form and location. They are of renewed interest to modern planners, but their history and that of coding reform generally are largely unexplored.

Purpose: This research traces the historical lineage of FBCs.

Methods: This work is based on archival research on historic codes regulating urban development. I also used secondary sources on coding history, both from the United States and abroad.

Results and conclusions: I describe examples from a long history of rules governing building form and placement, considering those intended to produce particular effects on urban form as direct antecedents of modern FBCs.

Takeaway for practice: Today's codes are more complex and difficult to implement than their predecessors. Modern FBCs require community participation and visioning to create consensus, whereas in previous historical periods such agreement was taken for granted and many aspects of urban form were dictated by technological and other constraints.

Research support: This article is one product of a larger research project on the history of urban codes. The research was funded in part by a grant from the National Endowment for the Arts. Further information can be found at http://codesproject.asu.edu/  相似文献

Abstract

Problem, research strategy, and findings: How do traditional forms of urban agriculture and the newer digital urban agriculture converge and diverge from one another in terms of land use and gentrification? I interrogate the subject of digital urban agriculture with data from 82 semistructured interviews and notes taken during public forms and tours of facilities. Respondents were located in Denver (CO; n?=?30), New York (NY; n?=?26), and San Francisco (CA; n?=?26) and held positions ranging from community organizers, investors, local food powerbrokers, and planners to engineers involved in facilitating urban foodways based on vertical farming, automation, and related technologies. I find digital platforms—systems exhibiting characteristics including real-time surveillance, artificial intelligence, and automation—share similarities with traditional urban farming systems. Both platforms have the potential to disrupt dominant political economies and also have links to gentrification and other inequitable land use patterns. Potential divergences include differences in a) social, cultural, economic, human, and built capital barriers and outcomes; b) land use life course; and c) zoning.

Takeaway for practice: Digital urban farming systems inhabit a regulatory gray area; respondents encountered agricultural, industrial, or commercial zoning permits. The “digital” aspects of these systems contributed to this ambiguity and are used by powerbrokers to obtain further zoning permission than is possible with traditional urban agriculture. Compared with more traditional urban farming systems, digital urban agriculture taps into different forms of human capital. Finally, my findings are inconclusive on the issue of land use life course. Some data indicate digital farms will remain in urban cores, whereas other evidence points to the eventual migration of these platforms to the metropolitan periphery.  相似文献

Abstract

The goods and services produced by urban forests can benefit both urban and rural communities. But there is a need to incorporate urban forests as integral and formal components into municipal planning programmes. The case is presented to indicate that significant municipal savings could be possible in establishing urban forests. Such forests are for the needs of the community, and can provide food, shelter belts, enjoyment, products, and employment, especially with labour-intensive management. The establishment of an urban forest is discussed with particular reference to a ‘model’ urban forest in Moore Park, Sydney. Suggestions are offered for future municipal action in establishing urban forests.  相似文献

Problem: Recently, public health researchers have argued that infill development and sprawl reduction may improve respiratory outcomes for urban residents, largely by reducing vehicle travel and its attendant mobile-source emissions. But infill can also increase the number of residents exposed to poor air quality within central cities. Aside from emissions studies, planners have little information on the connections between urban form, ambient pollutant levels, and human exposures or how infill changes these.

Purpose: We examined neighborhood exposures in 80 metropolitan areas in the United States to address whether neighborhood-level air quality outcomes are better in compact regions than in sprawled regions.

Methods: We used multilevel regression models to find the empirical relationship between a measure of regional urban form and neighborhood air quality outcomes.

Results and conclusions: Ozone concentrations are significantly lower in compact regions, but ozone exposures in neighborhoods are higher in compact regions. Fine particulate concentrations do not correlate significantly with regional compactness, but fine particulate exposures in neighborhoods are also higher in compact regions. Exposures to both ozone and fine particulates are also higher in neighborhoods with high proportions of African Americans, Asian ethnic minorities, and poor households.

Takeaway for practice: Compact development and infill do not solve air quality problems in all regions or for all residents of a given region. Planners should take differences in neighborhood air quality and human exposure into account when planning for new compact developments rather than just focusing on emissions reductions.

Problem, research strategy, and findings: Our study contributes to the ongoing debate about the ability of Maryland's Priority Funding Area (PFA) program to control urban sprawl. We develop an economic-based land use conversion model to estimate if the PFA program steers urban growth to locations inside targeted growth areas within a fast-growing, exurban county. The results indicate that the size of an agricultural parcel, its distance from urban parcels, its proximity to highways, the productivity of agricultural land, and location in or outside PFAs influence the probability an agricultural parcel will be converted to urban use. We find that some of the parcels experiencing the greatest market pressure for development are located outside PFAs, and Maryland's incentive-based strategy is not completely effective at preventing sprawl.

Takeaway for practice: Careful design of the location of entrances and exits on and off highways, limitation of agricultural parcel fragmentation, and vigilant control of land use change in unproductive agricultural areas can limit sprawl. Our analysis highlights, yet again, the importance of communication between transportation and land use planners.

Abstract

Focus in this paper is placed on the issue of inclusionary zoning and developer contributions to provide affordable housing in the City West and Green Square urban redevelopment projects. Both are ambitious inner city urban renewal projects which form key parts of the New South Wales government's urban consolidation policy and also seek to maintain a social mix through the provision of social (i.e. affordable) housing.  相似文献

ABSTRACT

This article explores public participation and its impact on urban structures in Southern Africa. Often, public participation stands in opposition to existing legislation and prevailing urban policies. Using textual analysis and case studies of Harare, Zimbabwe, Johannesburg, South Africa and Luanda, Angola, this study concludes that the urban fabric and structure of Southern African cities are in a state of instability. The rise of public participation–“right to the city”–has given way to “cities of rebels” in which citizens react or rebel against urban policies and legislation. These forces threaten sustainable urban morphology and service delivery, complicating the roles of urban planners and managers.  相似文献

Problem: This article addresses the increasing homogeneity of urban commercial areas and the loss of local culture associated with this trend. It seeks to identify strategies that build effectively on vernacular culture as an asset in neighborhood development.

Purpose: We aim to identify tools that advance the cultural preservation approach to urban economic development and to describe instances in which planners and neighborhood groups have applied these tools successfully.

Methods: We completed a wide-ranging literature review to identify the characteristics of places that have employed cultural preservation approaches and conducted six case studies involving 43 interviews in five cities.

Results and conclusions: Our interviews and case studies showed us that there are at least three types of anchors in neighborhoods with strong vernacular culture: 1) markets; 2) ethnic areas and heritage sites; 3) and arts-and-culture venues and districts. Although the balance between preservation and development will be different in each place, we did cull some widely applicable lessons learned while conducting our fieldwork: a) involve residents; b) find assets in local needs; c) transfer lessons rather than replicating others' work; d) create opportunities for ownership; e) if it doesn't exist, invent it; and f) balance culture and commerce. Our analysis also suggests that a neighborhood wishing to pursue a neighborhood development strategy based on vernacular culture should have at least one of the anchors listed above and strong, community-based organizations.

Takeaway for practice: We argue that it is both possible and preferable to advance an urban economic development strategy based on the local cultural assets that exist in urban neighborhoods. Our research illustrates different paths that places have taken to advance this kind of strategy and provides several ways for local planners and policymakers to integrate the maintenance of vernacular culture into their larger economic development plans.

Abstract

Problem, research strategy, and findings: Despite growing interest by practitioners in using exploratory scenarios within urban planning practice, there are few detailed guidelines for how to do this. Through the discussion of five case examples, we illustrate different approaches to linking exploratory scenarios to different planning contexts. We conclude by observing that to directly inform a plan, regardless of the specific approach taken, exploratory scenarios in urban planning must incorporate stakeholder values and not only rely on expert judgment and analysis.

Takeaway for practice: Exploratory scenarios are effective for analyzing uncertainty within a planning process. However, exploratory scenarios can be incorporated into planning practice in different ways, ranging from workshops among experts that aim to cultivate general learning to complex projects that result in highly detailed scenarios and recommendations for plans. Practitioners can draw on the cases we present to inspire planning methods for particular projects, taking into account specific contexts and goals.  相似文献

Problem: In 1997, the State of Maryland adopted a bold new approach to growth management based on a novel instrument: priority funding areas (PFAs). PFAs contain growth by directing state spending to areas designated by local governments and reviewed by the state government. Despite widespread acclaim and subsequent imitation, little is known about whether PFAs effectively contain urban growth.

Purpose: The purpose of this article is to evaluate the adoption, implementation, and performance of PFAs in Maryland in order to provide planners and policymakers with insights into their efficacy as instruments for managing growth.

Methods: First, we describe the statutory definition and mandated role of PFAs in state funding. Then, we describe the process used to create PFAs, the resulting pattern of targeted growth areas, the relationship between PFAs and local comprehensive plans, and the extent to which PFAs altered state spending. Finally, we examine the effects of PFAs on residential development patterns.

Results and conclusions: We find that PFAs have fallen short of expectations. The criteria used to establish PFAs produced boundary configurations that vary widely and are in many cases not ideally suited to managing urban growth. Ten years after their official designation, PFAs are not well integrated in land use decision making processes in many local jurisdictions. Finally, state agencies have not altered budgetary systems to monitor and guide the spatial allocation of funds and there is little evidence that after 10 years they have had any effect on development patterns.

Takeaway for practice: Targeting state funds to promote compact growth is a conceptually sound approach to urban growth containment, as land is less likely to be developed if it is not served by public infrastructure. But, as with other planning tools, the key is effective implementation. If states want to contain growth by targeting state spending, they must change budgeting processes to ensure that funds are spent appropriately and that the level of state spending is large enough to make a difference.

ABSTRACT

In this paper, the current situation and the carrying capacity of water resources in Wuhan urban agglomeration are analyzed. A comprehensive evaluation model is established to quantify the distribution of water resources and carrying capacity of cities in Wuhan urban agglomeration. The entropy method and synergistic theoretical model are applied to calculate parameters, and a series of indicators are also used to characterize the water resources carrying capacity in Wuhan urban agglomeration. The results show that water resources are in severe shortage and overloaded in Wuhan. It also tends to be overloaded in Ezhou.The larger protential of WRCC should be recognized in other cities of Wuhan urban agglomeration, such as Xiaogan, Huanggang, Qianjiang and Tianmen. Therefore, the rational planning and utilization of water resources, adjustment of industrial structure and the implementation of strict water-saving regulations are important for the protection of water resources and sustainable economic development of the urban agglomeration.  相似文献

Abstract

The ‘urban Aborigine’ has been a problematic figure in Australian social policy, because of the tension between his/her cultural status (apparently assimilated) and his/her politicised cultural identity (defiantly resistant to assimilation). This paper focuses on a moment in Australian history when a reformist intelligentsia was compelled to make better sense of the ‘urban Aborigine’, and on two intellectuals in particular: H. C. Coombs and Fay Gale. It then turns to the cultural practice of a particular sector of this intelligentsiathe urban Aboriginal painter ‐ and shows how urban Aboriginal artists have sometimes addressed the problematic category ‘urban Aborigine’ by richly referencing icons of the ‘traditional’ in their paintings.  相似文献

ABSTRACT

While planning has always had an urban emphasis it has also always been concerned with urban–rural linkages and the interactions between urban and rural as well as with the people, economy, and environment of rural places. This symposium issue of International Planning Studies presents recent scholarship on rural planning from around the world.  相似文献

Problem, research strategy, and findings: Municipalities across the United States are gradually recognizing urban agriculture as an integral part of planning, land use, and zoning ordinances. We review the literature on the regulation of urban agriculture at a moment when policy and regulatory vacuums exist and the acceptance and integration of urban agriculture is uneven. We review the current regulatory practices of 40 metropolitan and 40 micropolitan municipalities in the 4 U.S. Census regions. We find that municipalities are filling policy vacuums by adopting enabling ordinances (zoning ordinances, land use designations, resolutions), regulations on urban agriculture production (backyard animals, built structures, practitioner responsibility), and fiscal policy instruments (restrictions on sales of agricultural products, tax abatement, urban agriculture fees). Our findings support local planning practitioners in filling regulatory gaps, practitioners of urban agriculture in seeking how it’s done elsewhere, and researchers in discerning new applied and basic research projects. We identify 3 principal knowledge gaps: Planners need a complete typology of regulatory possibilities; a better understanding of how local, state, and federal legislations constrain or enable urban agriculture; and empirical evidence of the economic, social, and environmental impacts of urban agriculture.

Takeaway for practice: Planners should assess existing urban agricultural practices and consider which regulatory frameworks best support multiple local goals, incorporating a concern with urban agriculture into ongoing activities, deploying existing or innovative land use tools, facilitating institutional cooperation, and promoting inclusive decision making and community engagement.  相似文献

ABSTRACT

Risk and vulnerability assessment of urban water systems can be extended to include several components. This work formulates a probable quantitative assessment of risk and vulnerability of urban water system based on climatic conditions and urban population growth. Climate change scenarios and population projections are used to estimate susceptibility to water supply systems’ risk and vulnerability. Quantile regression was used to establish the exponent correlation between the climate variables and population; and evaluate their consequential influences on urban water supply systems. We complemented the analysis with a probabilistic model to assess the robustness of urban water system that depends wholly on the climate for freshwater source. The study established that Climatic conditions, though uncertain, point to freshwater deficiency in the future. Moreover, population trends project a higher urban population thereby increasingly lowering water per capita and subsequently leading to doubtful urban water system’s resilience to the exogenous pressures.  相似文献

ABSTRACT

Diverse urban theories discuss how economic processes shape conceptions of a city, but less research focuses on how pragmatic situations of urban life contribute to the characterisation of cities. We argue that pragmatic justifications reify socially constructed meanings of cities by creating a ‘spirit of urban capitalism.’ This framework conceives of two spirits: the market city, which aligns with neoliberal assumptions, and the people city, which foregrounds a resident-focused model. Using case studies of Copenhagen and Houston, we showcase how these conceptions of cities are justified by elites and residents, and thereby build empirical scaffolding connecting urban economies and cultures.  相似文献

Problem: Concurrent with the dramatic increase in the nation's elderly population expected in coming decades will be a need to dispose of larger numbers of our dead. This issue has religious, cultural, and economic salience, but is not typically considered a planning problem. Although cremation rates are rising, burial is projected to remain the preferred alternative for the majority of the U.S. population, and urban space for cemeteries is limited in many communities.

Purpose: We outline issues related to cemeteries and burial, describe a number of alternatives to traditional cemeteries, and explain how planners might usefully contribute.

Methods: This work is based on a literature review.

Results and conclusions: Alternatives to the cemetery are emerging, but remain limited. Some require changes to laws or public perceptions. Planning practice could be advanced by case studies showing how to integrate burial grounds into existing communities and how to alter public policy to permit alternatives to burial.

Takeaway for practice: As population demographics change, environmental concerns intensify, and demand for urban space grows, future land use decisions will have to balance a diverse set of social, cultural, and environmental expectations, including taking into account burial practices. There are only a handful of alternatives to traditional burial in a cemetery: burial in a multiple-use cemetery; natural burial; entombment in a mausoleum; cremation, with the ashes preserved in a columbarium or scattered elsewhere; and burial in a grave that will be reused in the future. This article provides planners with information about each of these alternatives, examples of how the planning process can address disposal of the dead, suggestions for avoiding environmental externalities, and ideas for better integrating the landscapes of death into community life.

Abstract

Problem, research strategy, and findings: The ability of planning to address America’s urban problems of inequality, crime, housing, education, and segregation is hampered by a relative neglect of Whiteness and its role in shaping urban outcomes. We offer a justification for centering Whiteness within urban planning scholarship and practice that would examine its role shaping and perpetuating regional and racial injustices in the American city. The focus of planners, scholars, and public discourse on the “dysfunctions” of communities of color, notably poverty, high levels of segregation, and isolation, diverts attention from the structural systems that produce and reproduce the advantages of affluent and White neighborhoods. Planners and planning scholars frequently invoke a “legacy of injustice” with regard to concentrated poverty and disadvantage but not in regard to neighborhoods of White affluence. One is segregated and problematized and the other is idealized.

Takeaway for practice: Planners and planning scholars need to understand the role of Whiteness, in particular White affluence, to assess the potential impacts of planning interventions. Doing so will inform a wider range of planning approaches to problems of racial and spatial equity.  相似文献
