Relevance:
Waikīkī, the economic hub of Hawai‘i’s tourism, is located at low elevation, adjacent to the ocean. It is threatened by flooding for multiple reasons: sea level rise, high tide flooding, high wave events, and/or periods of rain. There are anecdotal reports of basements and parking garages that flood regularly in Waikīkī under present conditions. As a major tourist destination, Waikīkī is too important to immediately retreat from sea level rise and will need to rely on an “in-place” adaptation strategy. Until this project started, no such strategy had been described in detail.

Response: This project is providing visionary and quantitative details to move the adaptation discussion forward. This research converges science with design to create conceptual design renderings as part of the near-term research to help visualize sea level rise adaptation methods, compel community discussion, and motivate large-scale decision making toward a positively adaptive built environment in densely developed coastal communities. In addition, the team is creating and will share the design brief used to guide the conceptual designs, which are based on input from stakeholders, precedent studies’ best practices, and emerging resilience guidelines.

Result: A design brief and initial renderings of adaptation strategies were drafted. Four two-hour workshops were held in 2021 with a wide range of stakeholder participants. Based on stakeholder input, two graduate fellows have created new renderings depicting adaptation strategies for two sites in Waikīkī with estimated sea level rise by the years 2050 and 2100. These renderings were presented in a public webinar on April 1, 2022. Using methods and feedback from the 2021 and 2022 project developments, two graduate research assistants, one climate resilience specialist, and one junior research assistant depicted a third site, which is located along the coast. The team created coastal, open space, and building and street renderings. Their work was presented in a webinar hosted on June 22, 2023. The project continues as the team reviews feedback and formalizes research for submission to academic journals.

2023 Presentation of Site-Specific Application of Flood Adaptation Strategies

The third focus site in Waikīkī is along the coast, and the renderings explore potential flood adaptation options for the iconic coastal area. Coastal, open space, transportation, and building adaptations were presented in renderings by team members Georgina Casey, Gerry Failano, Eric Teeples, and Desiree Malabed. Following presentations, a Q&A with expert panelists Lisa Rapp (architect, principal at AHL) and Joel Kurokawa (landscape architect, principal at Ki Concepts) proceeded, and audience interaction was encouraged through chat functions and poll questions.

The event was hosted by The University of Hawaiʻi, Sea Grant College Program Center for Smart Building and Community Design, in collaboration with the School of Architecture’s Environmental Research and Design Lab (ERDL) and the School of Ocean & Earth Science & Technology on Thursday, June 22, 2023, from 12:00 to 1:30 PM.

2022 Presentation of Site-Specific Application of Flood Adaptation Strategies

University of Hawai‘i Sea Grant College Program graduate research fellows, Josephine Briones and Ireland Castillo, from the School of Architecture presented architectural renderings depicting potential sea level rise adaptation strategies for two sites in Waikīkī. Expert panelists, Lisa Rapp (architect, principal at AHL) and Randall Wakumoto (engineer, Honolulu Department of Facility Maintenance) discussed the advantages and disadvantages of the strategies as they apply to each site. The audience of 121 stakeholders was polled for opinions. Questions and comments were taken from the audience.
