The number of emergency calls fielded by the Janesville Fire Department continues to rise, while the department's staffing levels continue to flatline. Car accidents and medical emergencies have been going skyward for years. And so far in 2016, those trends have been coupled with spikes in residential fires, water rescues and hazardous materials incidents. If projections hold, the department may hit the 10,000 mark for possibly the first time. “That is a concern,” Fire Chief Randy Banker said, referring to the swelling call volume. “We need to start getting some more personnel.” It's been a busy year for the department, which many people at City Hall believe to be operating at or near minimum staffing levels. Based on fire department data from January through June, the number of emergency calls for several types of incidents in 2016 are projected to surpass the department's average from the previous five years.
