Introduction Our spring 2022 University of Hawai‘i at Manoa School of Architecture graduate-level urban design studio investigated ideas for the near- and long-term re-introduction of nature-based blue-green infrastructure systems for climate and sea level rise adaptation into the fabric of the coastal primary urban center of Honolulu. Specifically, the class focused on a mauka to makai transect through Waikīkī, reaching from the northern bank of the Ala Wai Canal to the ocean—including the federal lands surrounding Fort DeRussy (below). Six graduate student teams, comprised of Master of Landscape Architecture and Doctor of Architecture candidates, have developed forward-looking, speculative urban design frameworks and concepts for future mixed-use that embrace open-ended, indeterminant, and dynamic environmental conditions, such as coastal flooding, rather than preventing them—all while promoting ecologically performative and culturally-appropriate “soft” solutions and learning from traditional native Hawaiian biocultural land-water practices. The conceptual, multidisciplinary student work developed in this design studio intends to stimulate discourse and contribute to a long-term vision for a resilient and adaptive Waikīkī that merges the seemingly conflicting goals of economic development, climate and sea level rise adaptation, ecological performance, social and environmental justice, and urban placemaking into mutually beneficial, sustainable relationships.

ARCH 743 Urban Design Studio Spring 2022 3

Nature-based Climate Adaptation Design Concepts for Waikīkī Course Catalog Description Urban design focused on Asia-Pacific cities investigating ecological, hydrological, social, cultural, political, and technological factors; study of historical precedents, block and/or open space typology, circulation, infrastructure, and context response. ARCH and LAND majors only. A-F only. Prerequisites: 733 and 742, or 761. Course Format ARCH 743 meets twice a week in School of Architeture Room 312 on Mondays and Wednesdays from 1:30 until 6:00 pm. Individual or group critiques, pin ups, student presentations, and individual work time comprise the majority of design studio sessions. Occasional lectures, guest presentations, field trips, in-class exercises, discussions, and readings supplement these course activities. Review of student work occurs throughout the semester. Each main studio phase concludes in a presentation, with a clear emphasis on the mid-term review and final review. Goals and Objectives This graduate-level urban design studio, through initial research, precedent studies, a sequence of analytical and mapping exercises, and conceptual, speculative design phases, explores urban scales, systems, and the role of landscape as infrastructure and driver of resilient urban form across a variety of spatial and temporal scales. The course stresses the importance of site analysis and locale-appropriate ecological urban concepts and sustainable design strategies. Focused on nature-based solutions, the course explores how to apply climate- and seal level rise-adaptation design principles to ecologically and socially resilient urban-scale built environment interventions and mixed-use development in Hawai’i. The critical goal is to understand and apply contemporary concepts of ecological urbanism, adaptation to climate change and sea level rise (SLR), water-sensitive low-impact development (LID), large-scale nature-based blue-green infrastructure, local food Ignisresource am, inctur systems, autem ius. carbon Hentionseque con pore dolorep elecerferuvsocial and environmental Ignis am, inctur autemcultural ius.

UHCDC Studio Context In 2016, the School of Architecture launched a public interest-driven community design center that engages needs of the state in all areas related to the quality and performance of built environments. The mission of the University of Hawai‘i Community Design Center (UHCDC) is to extend and augment academic research and instruction through faculty-supervised design, planning, placemaking, visioning, and outreach services of measurable benefit to the public. As a hybrid program of education and teaching practice, UHCDC offers Hawai’i a platform for faculty, professionals, and students to collaborate on interdisciplinary research and design projects that serve the public interest. This ARCH 743 studio offers students an opportunity to explore concepts related to a potential future UHCDC design research project that would contribute to an effort towards the development of a Sea Level Adaptation & Resilience Plan for the Waikīkī District. Class participants’ creative work serves as a unique academic asset, stimulates discourse, and thus supports the ongoing state-led Waikīkī resilience goals. The research and creative work generated in ARCH 743 would precede a UHCDC project team’s potential subsequent efforts. In turn, students registered in the course will gain invaluable real-world public-interest design and service experience.

ARCH 743 Studio Studio Overview Following initial research, precedent studies, urban-design-scale analysis, mapping, and planning phases, this speculative urban design studio investigates the near- and long-term re-introduction of nature-based blue-green infrastructure for climate and sea level rise adaptation. Pre-development, the project area (see page 3 above) was part of a drainage basin characterized by springs, streams (such as Pi’inaio Stream and its delta), and marsh land. Pre-Western contact, the ‘Ewa end of Waikīkī included the Hawaiian community of Kalia. It was characterized by numerous traditional fishponds (loko i’a), including the large Ka’ihkapu pond, and residences owned by native Hawaiian royalty. In 1908 the U.S. military acquired, occupied, drained, and filled a large parcel of land for the subsequent construction of Fort DeRussy. The urban design inquiry project area includes the mauka and makai banks of the Ala Wai, the canal itself, the residential and commercial areas to the north and south of Kalakaua Ave, Waikīkī Gateway Park, and a variety of facilities located on a large plat of federal land, including the Asia-Pacific Center for Security Studies, the US Post Office, Ainahau Triangle, the Kalia Road parking area, the various Hale Koa Hotel amenities (military personnel and dependents only), the U.S. Army Museum of Hawai’i, as well as Fort DeRussy park, boardwalk and beach, and the near-shore portion of the Pacific Ocean. The class’s goal is to advocate for the anticipation of climate-crisis challenges in Waikīkī through blue-green infrastructure framework development and urban ecological design that embraces open-ended, dynamic conditions, such as coastal flooding, rather than preventing them—all while promoting nature-based, ecologically performative “soft” solutions and learning from traditional native Hawaiian biocultural land-water practices. Comprised of graduate students in architecture and landscape architecture, the class will develop analyses, ideation, and overall long-term (6-ft SLR, anticipated ca. 2100 for the speculative purposes of this studio) visions and frameworks for sea level rise accommodation options in flood-prone areas of Waikīkī that decrease waterfront vulnerabilities by responding to inescapable shoreline changes, flooding, storm and groundwater inundation, as well as issues related to Honolulu’s aging conventional infrastructure. For the project area itself, student concepts will explore locale-appropriate, nature-based climate adaptation practices and opportunities for amphibious, blue-green infrastructure in both near-term (3-ft SLR, anticipated ca. 2050 for the purposes of this studio) and long-term (see above) visionary and bold illustrative urban design proposals. The essential drivers of urban form in these forward-looking visions will be multi-modal, non-automobile connectivity, multi-purpose coastal infrastructure systems, linked public hybrid open spaces, networks of ecological priority zones, and locale-specific, layered living shoreline systems as “soft” defense mechanisms against sea level rise and flooding, allowing for indeterminacy, increased biodiversity, improved ecosystem services, and, at the same time, education, decolonization, cultural restoration, and the creation of accessible urban waterfront amenities for all people.

Nature-based Climate Adaptation Design Concepts for Waikīkī Hawaiian Land Division

Aquaculture and Agriculture Brackish water fish ponds (loko pu'unone) surrounded the Pi‘inaio. The ponds were surrounded by taro (kalo). Not only were the fishponds and land productive, the ocean resources also were a huge asset. Over the years, a number of other crops, fruits, and trees were introduced and pleased the royalty that lived there.

The Project Site The site and its context As mentioned above, the class focused on a mauka to makai transect through Waikīkī, reaching from the northern bank of the Ala Wai Canal to the ocean—including the federal lands surrounding Fort DeRussy. Pre-development, the studio project area (also see page 3 above) was part of a drainage basin characterized by springs, streams, such as Pi’inaio Stream, and swamp land. Pre-Western contact, the ‘Ewa end of Waikīkī was part of the Hawaiian community of Kalia. It was characterized by numerous traditional fishponds (loko i’a) surrounded and residences owned by native Hawaiian royalty. In 1908 the U.S. military acquired, occupied, drained, and filled a large parcel of land for the subsequent construction of Fort DeRussy. The project area included the mauka and makai banks of the Ala Wai, part of the canal itself, the residential and commercial areas to the north and south of Kalakaua Ave, Waikīkī Gateway Park, and a variety of facilities located on a 72-acre plat of federal land (2066 Kalia Rd), including the Asia-Pacific Center for Security Studies, the US Post Office, Ainahau Triangle, the Kalia Road parking area, the various Hale Koa Hotel amenities (military personnel and dependents only), the U.S. Army Museum of Hawai’i, as well as Fort DeRussy park, boardwalk and beach, and the near-shore portion of the Pacific Ocean.

Instructor: Judith Stilgenbauer 10

Urban Design Parameters and Shared Assumptions Near-term, 2050 assumptions (for the speculative purposes of this studio): • 3-ft sea level rise (SLR) plus other coastal hazards (groundwater inundation, hurricane/storm surge, flooding, tsunami, etc.); increased ocean temperatures. Other anticipated climate-crisis effects. How does the project site adapt in innovative and resilient ways? • Proposed programs and uses will produce net-zero emissions and be carbon neutral. • No more individual, fossil-fuel/combustion engine vehicles permitted in Waikīki; shared, autonomous electric vehicles only, future electric public transit, water-based transportation, connections to rail; multi-use paths, walkability and bikes; public waterfront access. • The project site and its surrounding Waikīki neighborhoods, land, and water bodies begin to adapt and perform ecologically, provide ecosystem services (water, soil, air, etc.), and promote habitat, biodiversity, and productive and cultural practices. • Residents begin to live, work, recreate at or near the site.

Long-term, 2100 assumptions (for the speculative purposes of this studio): • 6-ft sea level rise (SLR) plus other, more severe and frequent coastal hazards (groundwater inundation, hurricane/ storm surge, flooding, etc.); increased ocean temperatures; other anticipated climate-crisis effects. How does the proposed mixed-use model neighborhood function in innovative and resilient ways? • Honolulu, Waikīki, and the proposed resilient mixed-use neighborhood will be climate-positive and, where possible, comprised of decentralized, self-sufficient off-grid systems (energy, water, sewage, waste, food, etc.). • No individual automobiles are allowed in Waikīkī, only shared, autonomous renewable/electric vehicles, future electric public transit, water-based transportation, etc.; consider connections to rail and mauka neighborhoods; multi-use paths, walkability and bikes; public waterfront access. • The proposed neighborhood’s open spaces, shorelines, and water systems perform ecologically, provide ecosystem services (water, soil, air, etc.), and promote habitat, biodiversity, food security, and cultural practices. • Social equity; jobs; social services; the majority residents live, work, recreate within walking distance. Basic design strategies for SLR and coastal flooding to explore and combine in urban design proposals: LINEAR BARRIERS Hard, engineered infrastructure systems that armor and stabilize the shoreline; examples: impermeable structures, levees, dikes, seawalls, riprap, dams, flood gates, storm surge barriers, etc. LIVING SHORELINES Soft, nature-based green infrastructure solutions; examples: wetlands, tidal marshes, other living coastal buffers that rely on ecosystem services and increase the distance between water and development, retain/absorb inundation, attenuate waves, slow erosion, provide habitat. ADAPTATION Elevated development; examples: raising the height of land, infrastructure, and built structures, using fill or pilings Floodable development; examples: structures/landscapes designed to withstand occasional inundation; elevated critical infrastructure Floating development; examples: floating buildings and infrastructure; elements are designed with fluctuating water levels in mind MANAGED RETREAT Withdrawal of development from the shoreline over time through managed abandonment of areas subject to frequent inundation; examples: structures designed for disassembly; conversion of abandoned areas into floodable, living shoreline elements, etc.

Context response Significant wetland ecosystems can be found around the island of Oahu, and around the Hawaiian Islands chain. Prior to the construction of the Ala Wai Canal in the 1920s, Waikiki and the south shore of Oahu accounted for one of those thriving marsh and wetland ecosytems. This project proposes to use the foundation of this historical precedent and re-create a contemporary interpretation of the area’s original ecosystem.

Student team: Delphine Homerowski and Matthew Lawson Instructor: Judith Stilgenbauer 14

Connecting Urbanism and Ecology

The overall vision is to connect the built environment and ecology to create a form of self-sustaining urbanism. This vision is based on three primary principles: • Sustainable built environment • Human scale urbanism • Ecological services

Five primary design goals guide the project. Floodability to embrace water dynamics, integration of ecosystem services for performance, vertical design to reduce the urban footprint, water-sensitive development for hazard mitigation, and reuse of materials and resources for a zero waste approach.

Nature-based Climate Adaptation Design Concepts for Waikīkī

Proposed design concept One primary element of the overall urban design is the marshland and sponge park, designed primarily to act as buffer against rising sea levels and to absorb possible flooding and storm surges, but also to serve as a recreational zone for residents and visitors. The mixed-use residential area would create a variety of public and semipublic spaces for residents to enjoy, supported by water-sentitive development solutions such as bioswales and living machines to address water collection and water treatment needs on site. Existing uses such as the resort area would be maintained, adapted, and made public.

Nature-based Climate Adaptation Design Concepts for Waikīkī

REDEFINING PRODUCTIVE A Closed-loop Climate-positive Community in Waikīkī Calling upon the historic productivity of Kalia in a revitalized way, redefining productive means focusing on water collection, filtration, and desalination, onsite clean energy, food growth and distribution, new forms of transporation, waste management, and a holistic approach to ecology.

Historic fish ponds, streams and springs Historic agricultural land

Map of Waikīkī’s historic productive fish ponds and ag land

Student team: Emily Sobolewski Knight and Eric Teeples Instructor: Judith Stilgenbauer 48

Redefining Productive

WATER

Tapping into water resources from the sky, the watershed, and pumped hydro reverse osmosis systems, an emphasis is placed on water reuse and utilizing saltwater as a resource.

ENERGY

Using the sun as the source of energy, the buildings incorporate pumped hydro systems for the generation of green energy at night when no sun is available.

FOOD

Edible trees, ag land plots, vertical hydroponics, and fishponds contribute to the food needs of the community, while still integrating spaces for recreation.

ECOLOGY

The reintegration of native ecosystems through the planting of trees, incorporation of wetlands, and living shorelines help tie the site together.
