Multi-Scalar Diagnostic

The regional analysis established environmental parameters, sea level exposure, water shortage, stream disconnection, fuel accumulation in abandoned agricultural terrain. This section converts those parameters into design logic. Seven principles guide the framework: residential rebuilding priority, space for return, no displacement, public access, buffered edges, multi-functional infrastructure, and cultural preservation. These are tested against the buffer strategy developed across coastal, riparian, peri-urban, and water-collection zones. Together they define a spatial logic grounded in Lahaina’s specific conditions rather than imported from elsewhere.

Multi-Scalar Analysis Framework

The thesis operates across four nested scales: regional, urban, neighborhood, site. Each scale isolates different variables while the framework tracks how decisions at one level constrain or enable outcomes at others. Regional analysis examines watershed hydrology; urban analysis examines street network redundancy; neighborhood analysis examines housing density and hub distribution; site analysis examines building performance and architectural resolution. The scales are not separate studies. They are layers of a single diagnostic that moves from territorial systems down to the material decisions that occupy them.

Regional Scale. I conducted topographic analysis at one-to-five-foot contour intervals, pairing GIS outputs with three-dimensional modeling to locate precisely where drainage concentrates, where gradients accelerate runoff, and where topographic pockets could retain water if infrastructure existed to capture it.

Lahaina occupies a position defined by environmental systems operating far beyond town boundaries. The West Maui Mountains intercept moisture-laden trade winds, producing orographic rainfall exceeding 300 inches annually at upper elevations while the leeward coast receives less than 15 inches. This gradient, steep, consistent, and directly correlated with water availability, determines what resources exist for capture, where collection infrastructure would be effective, and why the plantation-era ditch system represented significant hydraulic investment now abandoned. The analysis identified upland zones where rainfall capture should occur, transitional zones where interception infrastructure would slow mauka-to-makai flow, and coastal zones where accumulated runoff enters the ocean or, during the 2023 event, failed to reach suppression systems that needed it. Sea-level rise projections from the Hawaiʻi Climate Change Mitigation and Adaptation Commission defined the seaward boundary of the recovery framework; this data required synthesis across multiple state and county documents, none of which provided a single usable map. Through the development of this data and its 3D analysis we can imagine the expression.

The composite regional overlay establishes the edges, coastal exposure area, riparian corridors, peri-urban transition, hinterland watershed, that structure every subsequent design decision.

Urban Scale. Regional systems frame the town; urban analysis examines what the town contains. I mapped infrastructure networks, zoning distribution, and damage patterns through GIS overlay: floodable zones against sewage system status, historic district boundaries against burn perimeters, building footprints against post-fire aerial surveys. The layering revealed patterns invisible in any single dataset. Burn perimeter correlated with vegetation adjacency and building spacing; historic structures survived at rates no higher than recent construction; sewage and water infrastructure failed along predictable corridors where capacity had never matched demand.

Fire impact analysis required fine-grain resolution. From there post-fire destruction perimeters from aerial imagery and FEMA damage assessments were drawn. Comparative photography documented what remained: the Banyan Tree damaged but standing, heritage churches reduced to foundations, the elementary school gone. The burnt-versus-unburnt analysis isolated variables that correlated with survival: structures adjacent to irrigated landscapes or paved surfaces showed higher survival rates than those surrounded by dry vegetation; metal and tile roofs outperformed combustible alternatives; wider spacing between buildings reduced radiant heat exposure. These correlations inform placement and material specifications for resilient construction in the proposed framework.

Neighborhood Scale. The fire displaced over 6,000 residents and destroyed approximately 2,200 structures. Replacement housing must locate somewhere. The question is where, and at what density, in what configuration, protected by what buffer systems. I tested redensification scenarios within the proposed buffer framework, calculating how many units could occupy the protected zone between riparian and peri-urban edges at densities compatible with walkable urbanism and efficient service delivery. The 2,200-unit target matches structures destroyed. At average household sizes documented in pre-fire census data, this housing stock supports 6,000–7,000 residents, effectively the displaced population. The units distribute across 84 acres organized into three district typologies, all capped at four stories to maintain scale consistent with Lahaina’s historic fabric. Community hubs anchor each district at intersections of the proposed boulevard with major cross-streets, ensuring essential services remain within walking distance of all housing. Three hub types emerged from program analysis: Neighborhood Center with Primary School, Neighborhood Center with Health Services and First Response, and Neighborhood Center with First Response alone. The configuration is not fixed. It is a framework that can adapt as conditions change, as development proceeds, as community priorities clarify.

Site Scale. The site scale tests whether regional and urban decisions produce coherent architecture. I selected the elementary school hub as the primary demonstration, a functional node combining educational program with emergency capacity at a location anchoring the redensification zone. The design develops through plan, section, and module studies that resolve structure, environmental performance, and aggregation logic to a level that could be built. The site scale is expandable. This is the framework’s strength. When opportunity arose to test the logic in a competition, a fire station for the re-densified district, I applied the same principles to a different program and produced a coherent building. The framework does not prescribe form; it establishes relationships between systems that produce form when applied to specific sites and programs.
