Enhancing urban resilience and connectivity in Honolulu with elevation strategy

Abstract

As coastal urban centers face increasing threats from climate change, particularly sea level rise (SLR), the need for resilient urban design is more pressing than ever. Honolulu, where 70% of the population resides in vulnerable coastal areas, exemplifies the challenges of addressing both acute shocks and long-term stresses posed by SLR. This dissertation explores elevation as a comprehensive solution to these challenges, focusing on the integration of elevated infrastructure in the Waikiki district, where the application of elevation strategies to streets and the incoming elevated train system remains underexplored.After compiling a comprehensive literature review of similarly situated projects and elevated walkways around the world, this research investigates how elevation strategies can enhance urban resilience and connectivity while preserving Honolulu’s unique sense of place. The study aims to bridge the gap between elevated buildings and supporting infrastructure by developing design solutions that respect local cultural and environmental contexts. The dissertation is structured into two parts. The first part presents architectural design principles for elevated pathways designed to withstand SLR and other climate threats, particularly in tropical environments. The second part applies this framework to a model urban block in Honolulu, demonstrating how these solutions can inform future developments that prioritize resilience, functionality, and sustainability. The research employs a multi-method approach, including mathematical, environmental, and experiential comparisons, alongside simulations and stakeholder feedback. Ultimately, this research proposes a new standard for urban resilience that harmonizes local architectural traditions with the urgent global challenge of sea level rise.
