Problem, research strategy, and findings: Advocates of form-based codes contend that these zoning regulations go beyond conventional zoning regulations in promoting sustainable development. We examine the extent to which form-based codes adopted by California cities differ from conventional zoning regulations in integrating 41 Leadership in Energy and Environmental Design for Neighborhood Development sustainability criteria (measured by the total number of criteria and the strength of each criterion included in regulations) using a multiple-case study of 26 cities in Southern California. We examine whether and how form-based codes adopted for specific development areas differ from the conventional zoning regulations they replaced and from the current conventional zoning regulations of matched cities. We find considerable variation among cities: Not all form-based codes in our study include more sustainability criteria to a stronger degree than conventional zoning regulations, but a) most form-based codes include more sustainability criteria than the conventional zoning regulations they replaced and those of matched cities, and b) the strongest form-based codes include more sustainability criteria to a stronger degree than the conventional zoning regulations they replaced and those of matched cities. We lack sufficient information to generalize; California, moreover, has many state laws requiring sustainable development. Our findings provide valuable insight for cities considering zoning reform to increase the sustainability of development.
Takeaway for practice: Our findings suggest that form-based and conventional zoning regulations can each help cities integrate sustainability criteria into their development regulations. Our research offers positive examples of best practice in zoning reform and highlights missed opportunities for creating more sustainable communities. Cities considering zoning reform can consider these opportunities when reforming their codes to be more supportive of sustainable development. 相似文献

Municipal brown field redevelopment efforts have tended to assume that the sites involved were economically non-competitive. They have thus focused on public acquisition of contaminated property and direct incentives to specific on-site activities. The emergence of a growing number of entrepreneurial firms that redevelop brownfields-often with minimal public involvement-suggests limits to the efficacy of this approach for large and very “dirty” sites that continue to stand abandoned to the frustration of local planners and economic developers. New approaches to public support for such regeneration may be suggested by closer examination of the private brownfield entrepreneurs. This article reports the results of a survey of these developers, suggesting that planners can contribute to more efficient use of public economic development resources by recognizing when public intervention really contributes to, and when it may inadvertently detract from, the attractiveness of sites a community wants to see regenerated. 相似文献

反思控制性详细规划编制在城市更新地段面临的挑战,提出传统控制性详细规划教学的困惑。探索控制性详细规划编制教学的改革方向,在借鉴美国、日本、新加坡的经验基础上,指导学生编制《广州人民南城市更新片区形态条例》,其特点包括:采用面向开发者使用的文本形式;强调面向实施的土地开发指引;采取形态分区主导的形态条例,以取代传统基于功能分区和指标管控为手段的控规编制方法。形态条例是适应城市更新地区规划编制的积极探索,未来落实还需要结合规划制度的进一步改革完善。 相似文献

20世纪80年代末,传统以土地用途为核心的区划因无法预测城市空间形态而遭到批判,同时新城市主义、可持续发展及精明增长等新理念逐步兴起,提倡重塑步行空间和新邻里规划的回归。在此背景下,美国空间形态管制应运而生并逐步发展完善。本文阐述美国空间形态管制的背景缘起,梳理其内涵体系及演变脉络,并探索美国空间形态管制实施的地方化模式。之后,归纳评析其先进经验,为增强我国城市特色和空间形态提供思路。 相似文献

Minimum parking requirements, which mandate off-street parking and have been a staple of American zoning codes for more than 80 years, are slowly falling out of favor due to incompatibility with sustainable urbanism, equity, and social responsibility. A new zoning ordinance in Buffalo, New York completely removes minimum parking requirements citywide, relieving developers and property owners from the mandate to provide off-street parking. This article performs a comparative analysis of guidelines in the zoning code before and after reform and examines the public engagement process that produced the change in parking control. Strong support for and little opposition to this zoning change suggest less resistance than anticipated to policies that formalize a reduction in off-street parking facilities. Findings suggest that removing minimum parking requirements is easiest where off-street parking requirements are least needed, and that the planning team in Buffalo proposed a bold idea after it detected, from special interest groups and the public, initial support for removing parking requirements. The article provides direction for future research to evaluate the repeal of minimum parking requirement and its effects on transport, the environment, and the economy. 相似文献

This article describes best practices from contemporary scientific protocols that can be used to perform pre-construction validation of urban design guidelines. Because of the prominence of skylines in the urban landscape, their regulation represents a prime candidate for applying design guidelines. We tested guidelines for three prospective skyline factors: overall skyline shape (convex, concave, or flat), number of turns in the roofline of individual buildings (4, 8, or 12), and level of variance in four attributes of individual buildings: height, width, depth, and setback (low, medium, or high). Level of variance in building attributes had the strongest effect on judged pleasantness. The respondents preferred rugged skylines over simple ones, whatever their overall shape. These findings suggest that regulations for skyline appearance should focus on variances in the four building attributes. 相似文献

土地的开发利用应遵循既定的分区规划,若刻板执行分区规划给财产所有人造成实际的困难或不必要的困难时,财产所有人可以申请分区变更。但由财产所有人自己制造的困难、不具有特殊性的困难、财产所有人自身的困难、未实现最大经济效率的困难以及非因适用分区规划产生的困难,均不能构成认定困难规则中的"困难"。美国法上困难规则的司法认定标准,对于完善中国城市规划分区变更认定标准具有重要的启示意义。 相似文献

Climate change and sustainability expert Mark Watts imagines what it might be like to look back from the year 2050. What might the view be from his position as Executive Director of the C40 Cities Climate Leadership Group? What crucial political moves and actions might be required from global megacities if they are to address climate change and make the ultimate shift to a low-carbon world? 相似文献

迄今为止,在中国的城镇化进程中,乡土景观资源的保护与利用仍然是个未受到足够重视的薄弱环节。在社会格局剧变和文化高度融合的大背景下,隔离区域生态与文化特征的规划管理模式已无法适应人民对生活质量及其可持续性的更高追求。实现生态与文化视角的融合既是社会实践的要求也是学科发展的趋势。以福建北部地区为研究对象,在实施研究区生态与文化区划的基础上,以空间统计与地理信息技术为手段,验证了研究区生态与文化类型区的空间关联性,并据此构建了乡土景观分类及区划方法体系。对乡土景观区划成果在区域风景道规划及旅游资源空间管制等领域的应用途径做了初步探讨。本研究可视为是区域可持续发展战略中的有关乡土景观资源整合保护的一次有价值的实践探索。 相似文献

R&Sie(n)'s installation I'm Lost in Paris (2008), a disturbing take on the ecological house, epitomises the preoccupation of the French architect François Roche with the contradictions of modern nature. Javier Arbona tracks how Roche's notion of nature as ‘a partly human artifice’ which is both alien and personalised play out in his various projects, capitulating between attempts at overcoming alienation and heightening it.
