%X In recent years, the call for social impact assessment (SIA) in addition to environmental impact assessment has led to an increase in case studies. With Germany being a country without legally required SIA, and presenting a gap of research in the field, a case study of the extension of the tram line M10 in Moabit, Berlin was conducted. The research aim was to study how the social impacts were assessed and managed in the project, as well as to examine the public perception of that process. Qualitative methods in the form of participant observation and semi-structured interviews with a variety of stakeholders were conducted. The majority of the community has been excited about the prospects of connectivity but has raised concerns of pollution, noise, and logistical issues. On the other hand, the interviewees from the planning side have admitted to little consideration of SIA due to funding and staff issues. This shows that an implementation of SIA at an early stage in the planning process could offer room for compromise and a more holistic solution for the population's concern. %D 2023 %L theses_frw4225 %A Merle Karoline von Bargen %T Social Aspects of Infrastructure Development - The case of the M10 tram line extension in Moabit, Berlin
