Most <br />fire departments in growing areas such as Tukwila will see increases in activity, but <br />increases at this level will have an impact on the ability of emergency responders to <br />respond effectively. The increase is primarily driven by the growing number of medical <br />emergencies, which have increased 19.9 percent from 2012 to 2016. EMS incidents <br />account for 68.7 percent of all calls over the past five -years. The number of fires has <br />increased by 10.8 percent from 2012 to 2016. The number of false alarms has grown <br />14.5 percent, the hazardous materials responses have grown by 16.8 percent, and the <br />good intent calls have risen 38.8 percent over the five-year period. Map 3 below shows <br />the location of all incidents over the past five years. <br />Using the NFPA 1710 Standard for emergency response travel time of four -minutes <br />90% of the time for fire engines, the current station locations provide adequate <br />response travel time to all emergency incidents within Tukwila. Map 4 below provides <br />an overview of four -minute response travel times from the current fire stations for fire <br />engines. NFPA 1710 also specifies an eight -minute travel time for ladder companies, <br />Map 5 shows the current ladder company response within eight -minutes 90% of the <br />time. <br />In addition to the four -minute travel time, NFPA 1710 also includes metrics for an <br />effective response force (EFR), also referred to as an effective firefighting force (EFF), <br />of 17 firefighters arriving within an eight -minute time frame 90% of the time for 2000 <br />square foot single family dwelling fires. TFD and the neighboring fire departments would <br />not be able to meet this portion of the standard without the automatic aid provided by <br />the surrounding fire departments and TFD. The total on -duty strength for TFD is usually <br />14 firefighters. Map 6 illustrates the eight -minute response for an ERF of 17 firefighters <br />with automatic aid provided by surrounding fire agencies and TFD. Maps were also <br />developed for fire scenarios for a minimum of 15 firefighters and for high-rise fires, <br />requiring 26 firefighters within eight -minutes 90% of the time. <br />In analyzing the GIS data for Tukwila over 200 maps were created to illustrate several <br />scenarios for this study, as well as maps requested by the City during the study. Many <br />of the maps are included in this report to support the recommendations for fire station <br />Tukwila Fire Department — Station Location Study <br />June 2017 <br />41 <br />
