Project Title:
Connecting Urbanism and Ecology
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
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.
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.

New circulation pathways and access Proposed zoning
Phase I This phase would be implemented in the short-term to prepare for 1-2 feet of sea-level rise
Phase II This near-term phase would prepare the area for 3 feet of sea-level rise
Student team: Delphine Homerowski and Matthew Lawson
Phase III This final, long-term phase allows for 6 feet of sea-level rise

Single-loading buildings facilitates passive cooling for all residents while still allowing the comfort and familiarity of a lanai
Photovoltaics can produce energy year-round, reducing reliance on fossil fuels Hydroponic systems in each building create responsible and productive water usage while fostering community
Rooftop gardens can contribute both to community and ecological sustainability
