Blurred Lines: From Fragmentation to the Common on Urban Coastal Edges

Advised by Craig Douglas

This thesis investigates how ecological and social agents can facilitate the blurring of urban edges, reverse the historical progress of urban fragmentation, and enrich culture and publicness in the Bronx, New York City. From the 1930s to 1960s, directed by Robert Moses, the government transformed streets into expressways, parcels into superblocks, and urban voids into single-function open spaces, shaping excessive amounts of edges and lines. The fragmentation enforced social divisions. It displaced the preexisting communities, segregated racial groups, and caused social vulnerabilities.

This project regards climate change and projected sea level rise as an opportunity to initiate the agenda of urban progress by blurring lines to reverse fragmentation. The ecology acts as a means to activate the blurring, mediating the edges with water and land. It encapsulates the social interventions that engage with multiple social groups to generate diverse eco-hydro-social conditions, gradually transforming the fragmented spaces into a common landscape.
