Planning issues for urban waterfront Redevelopment projects are examined in this paper, based upon case studies in New York, London, Boston and Toronto. The research programme was based upon over 100 interviews with key actors in the four cities. The paper is oriented towards practical problems in the implementation of planning. It generally considers the perspective of the redevelopment agency to consider waterfront planning and development techniques. The specific issues which are addressed include changing the waterfront's image, improving accessibility and controlling the quality of the physical environment. An incremental approach to implementation is recommended, with emphasis upon controlling the quality of the public realm and the role of urban design guidelines to guide private development.

This two-part essay analyses the changing nature of the public realm in the evolving edge of the American metropolis and the implications for urban design and planning. Many forces are changing the form and use of public space in cities--concerns for safety and liveability, increasing dependence on telecommunications, decline in public revenues, the privatization of many amenities, and an increasingly pluralist society. The essay specifically focuses on the historical influence of planning and design practices on suburban form: density levels, land use and zoning patterns, suburban layouts and streetscapes. Field surveys and morphological analyses of urban edge patterns from the San Francisco Bay area document the current state of the suburban public realm. The second part of the essay will examine how physical planning can contribute to restoring a more vibrant public realm amidst raging debates over its changing nature and relevance.

A medium-density planned neighborhood designed for a centrally located piece of urban land in the 1970s invoked some specific social-mix targets for the residential population of some 850 dwelling units. The site plan was developed in accordance with explicit planning principles derived from the Pattern Language by C. Alexander et al. A postoccupancy evaluation of residents' status, attitudes, and behaviors suggests that the design of a successful environment for a socioeconomic population mix involves a delicate balance between privacy and community. Such a balance is more complex and requires more careful design and more subtle innovation than the simple "if-then" logic of the Patterns used in planning this neighborhood.

Within the International debates about the roles and relevance of planning and architecture, urban design is trying to find its place and clarify its contribution to city making. The products and the practice of urban design vary significantly in different global and socio-economic contexts and in relation to varying theoretical foundations. In South Africa, as in other developing countries, urban design is only beginning to feature as a valid mainstream concern within city development and among built environment practitioners. This paper presents the case of the City of Cape Town’s Dignified Places Programme as an example of implementation-focused urban design undertaken in a context where the conscious design and management of the public realm does not feature on the agendas of cash-strapped, basic needs-focused local government. The design and construction of new public spaces is the focus of this programme, but a parallel objective is to place the central concern of urban design – the quality of the public environment – squarely on the agenda of local government in Cape Town. The paper outlines the urban context in which it is being implemented sketches the issues that prompted its initiation and traces its theoretical origins focusing on the linkages between this theory and practice. The paper gives an account of the origins, objectives and strategy as well as the design principles that directed the form and location of the projects in the Programme. The paper finally reflects on the key successes and challenges of the programme and attempts to tease out lessons for both the theory and practice of urban design.

Jane Jacobs's The Death and Life of Great American Cities (1961) had an enormous influence on urban design theories and practices. This study aims to operationalize Jacobs's conditions for a vital urban life. These are (1) mixed use, (2) small blocks, (3) aged buildings, and (4) a sufficient concentration of buildings. Jacobs suggested that a vital urban life could be sustained by an urban realm that promotes pedestrian activity for various purposes at various times. Employing multilevel binomial models, we empirically verified that Jacobs's conditions for urban diversity play a significant role with regard to pedestrian activity.

By studying the mathematical properties of metrics, we identify three fundamental characteristics of distance, which are optimality, detour and break. In this paper, we explore the implications of these properties for transport planning, urbanism and spatial planning. We state that distances contain the idea of optimum and that any distance is associated to a search for optimisation. Pedestrian movements obey this principle and sometimes depart from designed routes. Local suboptimality conveyed by public transport maps has to be corrected by interventions on public space to relieve the load on central parts of networks. The second principle we state is that detour in distances is most often a means to optimise movement. Fast transport systems generate most of the detour observed in geographical spaces at regional scale. This is why detour has to be taken into account in regional transport policies. The third statement is that breaks in movement contribute to optimising distances. Benches, cafe´s, pieces of art, railway stations are examples of the urban break. These facilities of break represent an urban paradox: they organise the possibility of a break, of a waste of time in a trip, and they also contribute to optimising distances in a wider network. In that sense, break should be considered as a relevant principle for the design of urban space in order to support a pedestrian-oriented urban form.

Four urban public spaces, representing various designs and microclimates, were investigated in Gothenburg, Sweden, in order to estimate how weather and microclimate affect people in urban outdoor environments. The research strategy was both multidisciplinary and interdisciplinary and included scientists from three disciplines: architecture, climatology and psychology. The project is based on common case studies carried out during four seasons, including measurements of meteorological variables, interviews and observations of human activity at each place. Multiple regression analysis of meteorological and behavioural data showed that air temperature, wind speed and clearness index (cloud cover) have a significant influence on people’s assessments of the weather, place perceptions and place-related attendance. The results support the arguments in favour of employing climate sensitive planning in future urban design and planning projects, as the physical component of a place can be designed to influence the site-specific microclimate and consequently people’s place-related attendance, perceptions and emotions.

In a research project carried out in various neighborhoods in Stockholm, Sweden, we have developed a method for facilitating children’s influence on spatial planning. Our goal was to construct a vehicle for communication that could work in practice for both children and teachers as well as for planners. The method uses computerized GIS maps—a common tool in spatial planning. With little assistance, 10- to 12-year-old children map their routes and special places, mark activities and write comments. Teachers can also map routes and places used for education. The results have proved reliable and accessible by planners. Use of the mapping method within the school curriculum and in the planning process is broadly discussed in the paper.

The article concentrates on emerging relationships between physical characteristics of urban open spaces and their uses. It draws on a combination of behaviour mapping and geographic information system (GIS) techniques - as applied to urban squares and parks in two European cities, Edinburgh (UK) and Ljubljana (Slovenia) - to reveal common patterns of behaviour that appear to be correlated with particular layouts and details. It shows actual dimensions of effective environments for one use or more of them and shows how design guidance can be arrived at, based on the particulars of the case study sites and cities. In addition, the value of this article is in exploring GIS, a tool that is currently irreplaceable in spatial analysis and planning processes for urban areas, as a detailed analytical and visualisation tool that helps to describe inner structure of places revealed by behaviour patterns.

The climate of a city influences the ways in which its outdoor spaces are used. Especially public spaces intended for use by pedestrians and cyclists, such as parks, squares, residential and shopping streets, and foot- and cycle-paths will be used and enjoyed more frequently when they have a comfortable and healthy climate. Due to a predicted global temperature rise, the climate is likely to be more uncomfortable in the Netherlands, especially in summer, when an increase in heat stress is expected. As the phenomenon of urban heat islands (UHI) aggravates heat stresses, the effects will be more severe in urban environments. Since the spatial characteristics of a city influence its climate, urban design can be deployed to mitigate the combined effects of climate change and UHI’s. This paper explores these effects and tries to provide tools for urban design and strategies for implementation. Consequently, the applicability of the design tools is tested in a design for two existing Dutch neighbourhoods.

While the first part of this two-part essay portrayed the bleakness of the suburban public realm in the USA, the debate over how physical planning can contribute to making it more vibrant is the subject of this second part. Eurourbanism, or the practice of looking to European cities for a design paradigm, has been criticized on the grounds that the USA has its own distinct public realm which is either non-spatial in character or is located in 'non-traditional' public spaces, such as shopping malls, in contrast with the more 'traditional' European sites such as streets and squares. But there are questions about whether the distinctive 'American public realm' is as democratic, or can offer the diversity of experience of the 'traditional' public realm. A more recent addition to the debate has been 'new urbanism' or 'neotraditionalism', whose proponents have put forth a set of planning guidelines for suburbia by drawing on design principles embodied in the traditional American small town. The essay critically evaluates these guidelines by examining their application in two neotraditional develop- ments and proposes a research agenda to move the debate ahead.

The development of downtown public space has been increasingly defined by agreements negotiated between the public and private sectors. In the last decades the majority of downtown public space has occurred in the form of urban plazas, built as integral parts of privately owned office and retail complexes. In this paper we document the private production of public open space in the downtown areas of Los Angeles and San Francisco - two cities that have used distinctively different policy approaches in forming public-private partnerships. We examine how the process of public open space creation is affected by the culture of planning and development, and discuss similarities and differences in the imagery and form of plazas in the two cities. It is found that urban plazas are the reflection of a market-driven urbanism. As such they are quite homoge- neous in their form despite differences in the planning style and development process encountered in the two California cities.

This study attempts to comprehensively and objectively measure subjective qualities of the urban street environment. Using ratings from an expert panel, it was possible to measure five urban design qualities in terms of physical characteristics of streets and their edges: imageability, enclosure, human scale, transparency and complexity. The operational definitions do not always comport with the qualitative definitions, and provide new insights into the nature of these urban design qualities. The immediate purpose of this study is to arm researchers with operational definitions they can use to measure the street environment and test for significant associations with walking behaviour. A validation study is currently underway in New York City. Depending on the outcome of this and other follow-up research, the ultimate purpose would be to inform urban design practice.

There has been considerable debate over "New Urbanism" as a design strategy for adapting physical space to human needs. Among the interesting questions is whether people are willing to pay a premium to be able to live in areas characterized by New Urbanism design principles. If so, this willingness should be reflected in housing values. We test the hypothesis that urban design, specifically the design attributes associated with New Urbanism, are reflected in housing prices, using a data set for Haifa, Israel. House sales from 1988 through 1996 are analyzed for three neighborhoods in which there are similar socioeconomic compositions, public services, schools, property taxes, and other amenities. One of the neighborhoods has many characteristics of New Urbanism design, while the other two are more traditional urban or suburban developments. Hedonic regression analysis is used to control structure-specific characteristics, and an analysis of the regression values across neighborhoods shows a statistically significant price premium in the New Urbanism neighborhood. The evidence suggests that persons are willing to pay for living in a New Urbanism neighborhood, other things held equal.

Much of the recent interest in urban design has focused on the creation and management of public spaces of cities. My aim in this paper is to explore the nature and role of public space and its significance for cities today. I look at how the promotion of public space is, on the one hand, a concern for social and functional integration in response to social and spatial segregation of cities and the privatization of public space and, on the other hand, a vehicle of marketing localities and consuming places, all leading to multiple representations and meanings. I argue that it is important that the development of urban public space, as part of a larger, often despatialized public sphere, addresses these tensions and contributes to the emergence of an urbanism which promotes social integration and tolerance.

Drawing on ethnographic fieldwork in post-unification Berlin, this article examines the re-articulation of the problematic of “the social” in city planning. It juxtaposes the contrasting visions of city planners and youth workers for Alexanderplatz, a controversial square in Berlin’s eastern centre. I argue that the notion of “robustness” is helpful in understanding an important contemporary shift in thinking about planning and the social. In a sense, both planners and youth workers accused each other of taking insufficient notice of “the social.” While planners spoke of robustness as a technical, economic and aesthetic quality to which public space needs to aspire, the youth workers’ vision for Alexanderplatz was a proposal for a kind of “social” robustness where the social is, quite literally, built into the urban design. These ethnographic observations need to be understood in a context where city planning has been one of the most critical domains in which the tensions provoked by German unification are played out. Taking such socio-cultural specificities into account will lead to a more nuanced understanding of forms of neoliberal city planning.

There is a revolution underway in the interface between architecture and planning. Very recent research is enabling a novel understanding of the neuroscience behind how people perceive and experience the built environment. One such work, Cognitive Architecture: Designing for How We Respond to the Built Environment (Sussman, Ann, and Justin B. Hollander. 2015. New York: Routledge), argues for a set of testable principles for architecture and planning practice. Its overall line of investigation is that certain design characteristics of the built environment can influence brain wave production. Specifically, the interest lies in whether the presence of features suggestive of Cognitive Architecture is associated with certain brain responses. This working paper presents the results of a pilot study into this question, discusses technical issues and limitations and provides suggestions for future research avenues.

Creating “community” has long been a goal of urban planners. Although such rhetoric abounds in planning circles, what it all means is unclear. In this article, the authors review the community psychology and urban plan- ning literature, defining sense of community within the context of how the built environment might facilitate or impede it. They then present their research, which tests the effects of “main street” on sense of community in four San Francisco neighborhoods. Results indicate that respondents in neighborhoods exhibiting characteristics of a main street town (Bernal Heights and West Portal) have significantly higher sense of community than do respondents from a high-density neighborhood (Nob Hill) and from a more suburban-style city neighborhood (Sunset).
