Relocated on October 6, 2001, from its original Elmhurst address, Chula Vista Fire Department Station 4 on Paseo Ranchero doubles as the department's primary training facility for all 163 sworn firefighters. Engine 54 responds from this south-central position covering the Rancho del Rey and Telegraph Canyon Road neighborhoods, with the on-site training grounds providing live-fire evolutions, auto-extrication drills, and hazmat simulations that also serve as community-preparedness demonstration sites for nearby Chula Vista Recreation Center. The training division prepares all 163 sworn firefighters for the department's all-risk, all-hazard mission — including structural fire suppression, wildland-urban-interface response, swift-water rescue, and confined-space operations. Wildland brush apparatus housed at stations across the system deploy from Paseo Ranchero for fuel-modification inspections along the chaparral interface, supporting the fire-safe corridor program that coordinates vegetation management with community venues including Heritage Community Center. The station's heavy-rescue and light-and-air support units carry hydraulic spreaders, cutters, rams, and self-contained breathing apparatus refill capability for sustained multi-alarm operations.
