    Chicago\u27s Wall: Race, Segregation and the Chicago Housing Authority

    Get PDF
    When the Chicago Housing Authority (CHA) was created in 1937 the organization\u27s mission was to provide decent and affordable housing for low-income people. As thousands of African Americans migrated to Chicago from the South after World War II, a combination of public policy and private exclusion forced them to turn to the CHA for housing. Through political manipulation and racism, the CHA became a tool to segregate, confine, and conceal Chicago\u27s burgeoning African American population. By the 1960s, 99 percent of CHA tenants were African American and over 90 percent of CHA developments were located in predominantly African American neighborhoods. The purpose of this thesis is to examine the CHA\u27s role in segregating African Americans through three events in the organization\u27s history. After an exploration of the city\u27s historical background, the first event examined is the political struggle in the late 1940s that determined the location of future CHA projects in African American neighborhoods. The experience of an African American family that integrated a CHA project in 1953 and the rioting that followed is the focus of the second event. Finally, the construction of a figurative wall of public housing projects served to isolate, segregate, and concentrate thousands of low income African Americans. This blatant discrimination motivated a group of CHA tenants and a dedicated public interest lawyer to challenge the CHA\u27s racist housing patterns in court. The nearly twenty-year effort to end state sponsored segregation would be the dramatic conclusion to the CHA\u27s discriminatory housing policies and is the final event described. This thesis shows how the process of segregating African Americans took generations and undoing this public housing failure will take even longer

    Low carbon infrastructure investment: extending business models for sustainability

    Get PDF
    Investment in infrastructure is recognized as a key enabler of economic prosperity, but it is also important for addressing social and environmental challenges, including climate change mitigation and addressing fuel poverty. The UK Government Strategy Investing in Britainā€™s Future argues that significant investment in ā€œresilient, cost effective and sustainable energy suppliesā€ is needed to meet these challenges. However, current methods of assessing the costs and benefits of infrastructure investment, and the subsequent design of business models needed to deliver this investment, often prioritise partial economic gains over social and environmental objectives. This paper extends the business model canvas approach to allow designing business models and evaluation methods that can incorporate social and environmental value streams and propositions as well as economic values in order to facilitate genuinely sustainable infrastructure investment. It demonstrates the usefulness of this extension through two case studies of the development of smart grids for electricity distribution and local heat delivery networks in the UK. Smart grids are essential for maintaining the security and reliability of electricity systems whilst incorporating increasing amounts of low carbon generation in distribution networks. District heat networks can facilitate the efficient supply of low carbon heat. However, both will require significant levels of investment, co-ordination between public, private and regulatory actors, and will deliver a range of economic, social and environmental costs and benefits to these actors. Drawing on empirical interviews with local actors involved in smart grid and heat network developments, and recent work on valuation and business model canvas analysis, the paper challenges the traditional view of a business model as only creating one form of value. Accounting for multiple types of value helps to identify business models that are more likely to achieve the environmental and social goals of infrastructure transformation and opens the door for new actors. Finally, the paper introduces an approach to complex systems modelling of infrastructure investment decisions to take into account the range of actors and the diversity of motivations of these actors

    Evaluating the Effectiveness of Conformance-Based Plans: Attributing Built Heritage Outcomes to Plan Implementation Under New Zealand's Resource Management Act

    Get PDF
    Little is known about the effectiveness of district plans in protecting built heritage, which is a matter of national importance under New Zealand's Resource Management Act 1991 (RMAct). This is despite the fact that the RMAct directs planning agencies to evaluate the effectiveness of plan provisions. This lack of evaluation is not unique to New Zealand or merely symptomatic of heritage planning. Instead, it is a shortcoming in planning theory and practice internationally; a well recognised impediment being that planning lacks a suitable evaluation approach. This thesis aims to address this deficiency by proposing a methodology for evaluating plan effectiveness and applying it to the built heritage provisions of two district plans. The methodology adopted has been shaped by the theory-based and realist evaluation approaches, as developed in the field of programme evaluation. Both approaches share a common ontology regarding claims of causality, which stresses 'knowledge in context'. Thus, a central endeavour of the research is not only to identify the environmental outcomes arising from plan implementation, but also to understand how and why the implementation context promoted or inhibited the achievement of plan goals. In so doing, the causal and implementation theories underpinning the plans' heritage provisions are exposed, modelled and tested. The findings reveal that plan implementation failed to prevent the loss of built heritage values in many instances. While the plans' causal theory was largely sound, key aspects of the implementation theory were not realised during the development control process. Plan quality was a significant factor, as was the commitment and capacity of developers to comply with the plans. The institutional fixation on consent processing speed rather than environmental outcomes was a further impediment. Overall, the theory-based approach provided a useful framework for determining plan effectiveness and holds promise for evaluating plan issues other than built heritage
