This seminar examines the critical relationship between architectural practice and the growing threat of resegregation in America. Participants will explore how historic design and planning practices like redlining, urban renewal, and exclusionary zoning have contributed to racial and economic segregation. The session will analyze current challenges to diversity, equity, and inclusion initiatives and how these challenges may accelerate spatial inequities in housing, education, and public spaces. Using case studies and historical examples, the presenters will demonstrate how Design Justice principles can be applied to counter resegregation through intentional design interventions. The seminar will address community engagement methodologies, advocacy approaches, and specific design strategies that promote spatial equity. Participants will examine the ethical responsibilities of architects in creating built environments that either perpetuate or disrupt patterns of segregation, and develop practical tools to advocate for more equitable communities.
