Station 3 is located on the east side of I-19 on Camino Josephina. The square footage of the station is 9,187 and was built in 2011 for a cost of $3.8 million as a result of a voter-approved bond. Two personnel are located at Station #3, providing advanced life support (paramedic) emergency medical and fire response. Staffing at this station is occasionally reduced to one Firefighter/EMT to accommodate staffing needs at other TFD stations. Station #3 personnel respond to a vast residential area susceptible to brush fires. The station houses a medical helicopter crew (LifeNet) to assist with emergent transports to hospital facilities in Santa Cruz and Pima Counties. LifeNet reimburses the Fire District annually for use of Station 3.
