This paper presents a probabilistic methodology for the prediction of post-earthquake community recovery over time, based on a set of socioeconomic resilience parameters and a post-earthquake damage indicator. Pre-existing socioeconomic conditions are widely associated with the ability of a community to recover following an earthquake and, therefore, should be considered in a recovery prediction model. The city of Napa, California and the monitored recovery from the 2014 South Napa earthquake were used as a case study for the development and validation of the proposed methodology. The documentation of the recovery, which is herein associated with the recovery of the building stock, was accomplished via field surveys over a period of 18 months following the event. In addition to community-level recovery predictions in different areas over time, the methodology allows for the identification of the pre-existing socioeconomic parameters that most significantly affect the recovery trajectory. Thus, emergency managers can identify critical areas that take longer to recover, as well as identify strengths and weaknesses of their communities and respectively promote or address issues that facilitate recovery.

Following a flood the functioning of critical infrastructure (CI), such as power and transportation networks, plays an important role in recovery and the resilience of the city. Previous research investigated resilience indicators, however, there is no method in the literature to quantify the resilience of CI to flooding specifically or to quantify the effect of measures. This new method to quantify CI resilience to flooding proposes an expected annual disruption (EADIS) metric and curve of disruption versus likelihood. The units used for the EADIS metric for disruption are in terms of people affected over time (person × days). Using flood modelling outputs, spatial infrastructure, and population data as inputs, this metric is used to benchmark CI resilience to flooding and test the improvement with resilience enhancing measures. These measures are focused on the resilience aspects robustness, redundancy and flexibility. Relative improvements in resilience were quantified for a case study area in Toronto, Canada and it was found that redundancy, flexibility, and robustness measures resulted in 44, 30, and 48% reductions in EADIS respectively. While there are limitations, results suggest that this method can effectively quantify CI resilience to flooding and quantify relative improvements with resilience enhancing measures for cities.

Drawing on and developing literatures on automobilities, vertical urbanisms and the use of storylines to understand mega transport projects, we imagine infrastructure as a shifting assemblage of actors, storylines and material objects and practices. In the case of motorway building, this requires an understanding of how competing storylines about how both the infrastructure itself and the city it is located in are mobilised and politicised across diverse local geographies and multiple scales as the process proceeds. Our case study focuses on WestConnex, a 33 km motorway being built in Sydney, Australia. Similar to other major transport infrastructure projects, WestConnex morphed over time, growing in ambition, budget, complexity, debate and by enrolling new actors.

The digital re-creation of a past city represents more than a mere depiction of its historical awareness; it also represents its imaginability. In retrospect, the imaginability of the city corresponds to the outcome of various perceptions that we have acquired of it over time, and which currently confers us with a certain degree of accuracy in its readability. The imaginability of the city is therefore a determining factor in virtually re-creating the latter and subsequently converting it into a memoryscape. This theory can be validated by the specific case study of Lisbon, Portugal, which has during the last few years been the subject of at least four projects that sought to virtually re-create the city’s past. Despite presenting themselves distinctively with different technological applications, the four projects held the same starting point; the great Lisbon earthquake of 1755 (a major disruptive event in its history), and were all focused on presenting the cityscape that was lost as a result. Lisbon’s iconography from the sixteenth century to the mid-eighteenth century (drawings, engravings, and paintings) was used as crucial data.

In the 1950s, the city of Casablanca underwent a surge in demographic growth. Having become a strategic port during the French protectorate, it quickly had to accommodate more than 140,000 new arrivals from the countryside. The most extensive urban development project in the city was Carrières Centrales, introduced as a case study in the CIAM IX by the GAMMA team. Michel Écochard, Candilis and Woods reinterpreted the traditional Moroccan house in a compact horizontal fabric as well as in singular buildings. This became the typology not only for a house, but for the whole city. A revisit to Carrières Centrales 65 years after its construction provides an understanding of the metamorphosis that the urban fabric has undergone over time. The critical analysis in this research aims to uncover the main architectural and social parameters that have influenced its transformation. To achieve this goal, fieldwork was carried out during a research trip in October 2018. The work involved contacting local professors, accessing the archives of the University of Casablanca, interviewing the residents, and redrawing and graphing all the architectural elements that had changed since their construction. The urban fabric of Carrières Centrales was found to have evolved in a way that supports the following hypothesis: if an urban model imported into a developing country does not adapt to the changes in the life of its residents, it is considered a failure.

The purpose of the study is to identify areas that are possibly gentrified or in the process of being gentrified, through a localized typology of two components: youthification and an increase in the quality of life. This typology can be applied in similar investigations. Thisd paper addresses the case study of the Metropolitan Center of the City of Monterrey (CMM), Nuevo León, Mexico. The current urban regeneration plans and the increase of housing density in the CMM have caused a vertical real estate “boom” of apartment buildings and have strengthened the emergence of gentrification in the area, understood here as the decrease in social backwardness (increase in the quality of life) over time, with an increase in young adults (25 to 34 years-old), compared to older adults (60+ years-old). This article suggests a procedure to measure gentrification by overlapping the Index of Social Backwardness (ISB) at the Basic Geostatistical Area (AGEB) level, with a youthification index at the electoral section level between the 2010-2020 period. Both the decline of social backwardness (2010-2020) and youthification (2010-2020), are analytically articulated for successive census years, to generate a localized typology of the gentrification process.

This research examines management processes that lead to the omission of $2.3 million in betterment fees in the City of Cape Coral (City). It concentrates on management processes, data problems, and personnel issues that contributed and resulted in developing properties completing the Planned Development Process (PDP) without checks from critical areas in the financial system. This research analyzes how betterment fees, often called Contribution in Aid of Construction (CIAC), were designed, collected, and managed. This case study also outlines key measurement processes neglected by the City and demonstrates how management corrected the issue of lost revenue through errant billing by analysis and reengineering of the system. Despite hours of public debate and input from concerned citizens, this issue has continued for approximately 10 years. A 2004 betterment list is substantially increased and contains some properties listed on the original 1996 list. The issue is still as controversial as ever and efforts to address it seem to be ignored or minimized.

Abstract This study applies the BRIC – Baseline Resilience Indicator for Communities – as a case study to the city of Porto Alegre. The purpose of quantifying resilience is to allow the identification of the constraints of that city considering its 17 participatory budgeting regions to increase resilience over time. Utilizing five TOC focusing steps is suggested so that the identified constraints may be exploited and “broken” effectively. At the end, three significant constraints were identified, which lead to the conclusion that there is room for improvement in the city and in the adequacy of the tool regarding the proposed case, enabling further research opportunities.

Urban Resilience has recently emerged as a systematic approach to urban sustainability. The malleable definition of resilience has rendered its operationalisation an intriguing task for contemporary cities trying to address their organisational problems and confront uncertainty in a holistic manner. In this article we investigate the implementation challenges emerging for Resilient Strategies by the inattention paid to urban geological risk. We conceptualise urban geological risk as the combination of urban geohazards, geological vulnerability and exposure of the built environment and focus on the case study of Thessaloniki, Greece, a city that joined the 100 Resilient Cities initiative in 2014 and published its “Resilience Strategy 2030” (RS) in 2017. After a review of the RS, historical records of natural hazard events and with evidence gathered through interviews with city officials, we emphasize on earthquakes and surface flooding as the most relevant geohazards for Thessaloniki to tackle in its journey towards urban resilience. First, we examine geological vulnerability to earthquakes in conjunction with exposure of the built environment, as an outcome of ageing building stock, high building densities and the urban configuration, in Acheiropoietos neighbourhood, within the historic centre of the city. Then, we explore geological risk to surface flooding in Perea, in Thermaikos Municipality, with a particular focus on flash floods, by demonstrating how limited consideration of local geomorphology as well as semi-regulated urban expansion and its limited connection with emergency planning increase exposure of the built environment to surface flooding. Finally, we come up with the major implementation challenges Thessaloniki’s RS faces with regard to urban geohazards.

This chapter analyzes city branding efforts in Istanbul in the context of urban tourism. The chapter focuses on the evolution of promotional practices from disorderly and inconsistent marketing strategies to a coherent city brand. This relatively brief but complex history of city branding in Istanbul is divided into three analytical and interrelated phases: Self-Orientalism, the City of Religions and the Multi-Faceted City. In analyzing this process, the main representations, themes, slogans and other methods of city branding are discussed. In doing so, this study attempts to introduce a historical/chronological approach to the city branding literature in the case of Istanbul. Next, in the light of this approach and the case study, the study aims to discuss general implications and reasons about changes of city brands over time.

Prayer hall, where traditional Muslim prayers take place, is the most important element of Masjids (mosques). Prayer halls are historically shaped as simple orthogonal walled spaces. Over time, little changes have occurred to them. Recently, with the evolution of architectural schools of thought and the advent of new construction and electromechanical systems, prayer halls have been subject to creativity and experimentation. Architects designed prayer halls with different shapes, spatial configurations and forms which, in some instances, contradict with the essentials of prayer. This research attempts to monitor and classify different types of contemporary prayer halls according to their spatial configuration with special reference to the Saudi Arabian context. Taking the city of Jeddah as a case study, a representative sample of masjids is surveyed, documented, analyzed and classified. The analysis is based on shape, enclosure, symmetry and complexity of prayer halls space. The study concludes basic and non-basic prayer halls and their corresponding bisects. The classification, however, constitutes a base upon which design criteria for prayer halls across the Islamic countries can be built.
