Problem: Planners may read plans often, but the profession continues to view the interpretation of plan content as something that is either too obvious or too unimportant to require explicit discussion. Plans are seldom adequately interpreted. This is regrettable because plans contain a rich variety of content and meaning. Purpose: This article calls for planners to “read through” plans, not just to grasp their essential ideas or the means of implementing those ideas, but also to perceive additional levels of meaning relating to a) a plan's place within a larger intellectual sphere, b) a plan's statement on the social and political values of the time, and c) a plan as a part of the history of the planning profession and the life of cities. Methods: I propose a visual approach to plan reading descended from Panofsky's (1939) theory of iconology and use this to examine three very different plans that describe different size cities (small, large, very large) during different periods over the past 80 years (the 1930s, 1960s, 2000s). I analyze three levels of meaning in each plan: its factual meaning, or “plain sense” (Mandelbaum, 1990); its contextual meaning, or relation to political, social, economic, and physical conditions; and its temporal meaning, or setting within the scope of observations made by other plan readers in the perspective of elapsed time. Results and conclusions: Factual readings show that information may be found in diverse aspects of a plan document, from seemingly superficial aspects like its cover to unarguably central elements such as recommendations. Factual readings depend on understanding the relationships among different elements, and reveal information about the plan and its framers that may not otherwise be readily apparent. Contextual readings show us that plan recommendations are as much a product of contemporary conditions and norms as they are of plan-specific “survey and diagnosis” (Nolen, 1936). This raises the question of whether plan quality is to be judged only in terms of skillful execution of concerns of the day or whether innovation is also important. Temporal readings reveal that plans and planning have changed dramatically over time, simultaneously confirming and questioning the conventional wisdom of planning history. Takeaway for practice: Many planners read plans on a regular basis, and plans continue to constitute the major printed currency of the planning profession. Both plans and planning will benefit if planners become more discerning readers of the profession's principal idea vessels. Formal plan interpretation is rare, but each planner can become a better plan interpreter. Research support: None. 相似文献

Although prohibited by the federal Fair Housing Act of 1968, studies in the 1980s found that racial steering by real estate agents in the U.S. was still occurring. That legislation was strengthened in 1988, but throughout the 1990s, no study examined whether these tougher strictures helped eliminate steering. In 2000, HUD and the Urban Institute conducted the national Housing Discrimination Study in 20 U.S. metropolitan areas to replicate and extend that earlier work. In this article, we report the results of this latest study, which examined three types of steering and three steering mechanisms, all at three geographic scales. The results indicate that steering of all types is occurring when Black and White homebuyers are involved. In at least 12 to 15% of the cases, agents provided gratuitous commentary that gave more information to White homebuyers and encouraged them to choose homes in areas with more White and fewer poor households. Steering is less prevalent when Hispanic and White buyers are involved. We also found no evidence that steering declined over the last decade, despite the toughening of the federal legislation in 1988. We conclude by discussing the implications for interracial wealth differentials and new fair housing enforcement initiatives. 相似文献

The architect and planner Michel Ecochard has had a long career in developing countries, from its first works in Syria under the French rule, until the 1970s. He represented the modernist and functionalist approach to planning in a time of modernization. In this article, we concentrate on his work in Lebanon and Syria between the end of the 1950s and the 1960s. He prepared the master plans of Beirut and of Damascus. Those works represented the end of an era rooted in colonial planning. It was also the beginning of a new time, with the local planners taking on, sometimes sharing, sometimes contesting Ecochard's visions. Building on recent scholarship on the circulation of planning ideas, we focus on the reception of Ecochard's proposals. Though most political elites and planning professionals shared most of Ecochard's views, the political circumstances and the changing social conditions led to adjustments and reorientations. The new planning framework was also a major factor of change. 相似文献

This article reviews the history of the governance approaches and planning and funding tools utilised for regional public land acquisition in Perth and Sydney. Focus in this analysis is placed on the hypothecated land tax model used in Perth of the Metropolitan Region Improvement Tax (MRIT). The main outcome of the comparison and contrast of the approaches taken in Perth and Sydney is to present the case for the extension of the “Perth model”, which includes the MRIT, to other Australian cities. The benefit, from the perspective of the implementation of public policy and strategic metropolitan planning, of the availability and utilisation of a hypothecated tax for public land acquisition, is a key conclusion of this article. 相似文献

ABSTRACTThe nineteenth-century master plans for European cities influence their development beyond their intended lifespans and provide a variety of robust urban fabrics to this day. The Hobrecht Plan for Berlin's urban expansion (1862) was intentionally conceived to adapt to an uncertain future, remaining influential even today. For a considerable time, the Hobrecht Plan was disregarded and considered irrelevant across the spectrum of development plans in Europe. This article presents a comprehensive re-assessment of the Hobrecht Plan with an emphasis on its intrinsic value. The plan defined a new set of urban patterns, forms and spaces in 15 section plans and a range of public space typologies defining Berlin's cityscape. The plan developed a spatial and structural framework using three different urban design elements: the ring boulevard, the harbour square, and the neighbourhood square. These key organizing elements have helped public spaces remain the effective planning units of Berlin's neighbourhoods. This analysis provides insight on how contemporary master plans can better formulate long-term strategies to address complexity, adaptability, and flexibility. The article presents novel outlooks on Berlin's city structure and new knowledge of Hobrecht's contribution to the planning discipline. 相似文献
