"The survivable window in a fast-moving wildfire is approximately 30 minutes. However, independent modeling by a neighbor - veteran engineer and professor of engineering DerChang Kau - using road geometry, household counts and standard evacuation modeling assumptions estimated that Linda Vista residents would need 93 minutes to reach safety."
"Last October, the city received its own expert study from Fehr and Peers. The study found evacuation demand on key corridors serving this neighborhood exceed 200% of roadway capacity. The city had it for nearly five months before the Feb. 24 Planning Commission hearing where a proposed 51-townhome development on a 2.53-acre site on Linda Vista Drive was approved in a narrow 3-2 vote."
"Despite its direct relevance to evacuation capacity in this Very High Fire Hazard Zone, the Fehr and Peers study was neither presented nor discussed at that hearing. Should the council vote to finalize a project when the city's own technical findings about evacuation capacity were never formally entered into the record of the proceeding that approved it?"
Cupertino approved a residential development on Linda Vista Drive, located in a Cal Fire-designated Very High Fire Hazard Zone, despite critical evacuation concerns. Independent modeling by a resident engineer estimated residents would need 93 minutes to evacuate, far exceeding the 30-minute survivable window in fast-moving wildfires. The city possessed a Fehr and Peers study showing evacuation demand on key corridors exceeds 200% of roadway capacity, yet this analysis was neither presented nor discussed during the Planning Commission hearing that approved the project in a narrow 3-2 vote. The city council now faces the question of whether to finalize the project given that its own technical findings about evacuation capacity were excluded from the approval record.
