| Abstract: |
Structures rebuilt after the Oakland Hills "Tunnel Fire" in 1991 are different in many aspects when compared to their predecessors. Data obtained from the city of Oakland indicate homes have been rebuilt 28 percent larger (square feet). About 50 percent of the homes destroyed have been rebuilt, and building permits have been issued for an additional 16 percent. New construction mandates facilitated by local and State laws have resulted in the following requirements: class A roofs, chimney spark arrestors, 1-hour siding for exterior walls, 30-foot clearance of wildland vegetation. Domestic vegetation is not regulated. Average structural fuel load consumed in the fire was 11.5 kg/m^2. Larger homes built after the fire will produce higher structural fuel loads. Improvements in infrastructure such as roads and water supplies have not occurred. Improvements have occurred in communication systems. Increases in structural fuel load accompanied by modest improvements in infrastructure may increase the fire risk in this urban/wildland intermix. |
