Rising Above: Innovative Solutions for Waikīkī’s Sea-Level Challenges

The University of Hawaiʻi at Mānoa-led Waikīkī sea-level rise adaptation project has earned national recognition, winning a design award from the Society of American Registered Architects (SARA) for its innovative and resilient architectural solutions. Spearheaded by experts from UH’s School of Architecture, Hawaiʻi Sea Grant, and the Climate Resilience Collaborative, the project combines scientific research with community-driven design to address the pressing challenges of rising sea levels, coastal flooding, and groundwater inundation in Waikīkī. This recognition underscores the importance of integrating cutting-edge science into urban planning to create sustainable and adaptable coastal communities.

The team’s research, published in Technology/Architecture + Design, highlights strategies like relocating critical infrastructure, elevating utilities, and implementing stormwater management systems as part of a holistic approach to mitigating flood risks. By engaging local stakeholders and applying scientific data, the project provides scalable solutions that can serve as a model for other vulnerable coastal areas. These efforts reflect a commitment to advancing climate resilience through interdisciplinary collaboration and design innovation, earning the team a nomination for Climate Hawaiʻi’s 2024 Climate Leadership Awards.

UH Mānoa leaders stress the urgency of addressing long-term sea-level rise impacts, as emphasized by the IPCC, which warns of centuries of continued rising seas. Interim Dean Chip Fletcher highlights the potential consequences for Hawaiʻi, including becoming unsafe and unaffordable without effective policies and proactive planning. The project serves as a critical step toward building a resilient future, demonstrating the power of combining architecture, climate science, and local input to ensure that Hawaiʻi’s communities can adapt and thrive amid climate challenges.
