Figure 1 shows the total number of incidents per year, Figure 2 shows the breakdown of incident types over the last five years and Figure 3 shows incident types for 2019. Figure 1 Figure 2 Figure 3 4 | P a g e The factors that drive the community’s service needs were examined in a precise manner to determine the capabilities necessary to adequately address the risks that are present. The assessment of risk is critical to the determination of the number and placement of resources, and to mitigation efforts. Based upon the risk categories and the establishment of service management zones, the process can begin to build a system that will objectively determine the District’s capacity to provide service at the level the citizens expect. An important part of the risk assessment is determining what the risks are as well as their likelihood and consequences. The District looked back over the past five years at the types of incidents and the number of times they occur. From this information the probability of an event was determined. Figure 4 is used to determine the distribution or concentration of the resources throughout the District to match the risk. The different quadrants require a different commitment of resources. Resources are distributed around the District (fire stations with individual engine companies) to intervene as individual stand- alone resources in low and moderate risk incidents. Additional resources (tower, rescue, brush, medic units) are concentrated around the Figure 4 areas where the risk is higher or are in a position to complement the individual engine companies in intervention. For instance, a single engine company can suppress a dumpster fire, but multiple resources are necessary to supress a structure fire. It is reconized that there are events that are beyond the scope of the incidents that occurred in the last five years. The District interviewed the firefighters on the types of incidents they could foresee and evaluated county/city disaster plans to ensure no possible event was overlooked. These events are evaluated in the Standard of Cover. Each type of incident was also evaluated based on life safety (the amount of personnel and equipment required to rescue or protect the public and firefighters from life-threatening situations), economic impact (loss of properties, income or irreplaceable assets), and other impacts to the community (loss of historic buildings or community infrastructure). This evaluation determined the probability of the event. Table 1 is the result of this evaluation. 5 | P a g e Frequency -v- Risk 2014-2019 (Number of Incidents) Low Risk Moderate Risk High or Special Risk NFIRS NFIRS NFIRS Count Count Count Type Code Type Code Type Code Commercial Carbon monoxide Natural gas or LPG 424 376 412 760 Structure 111 118 incident leak Fire Cooking fire, Structure fire confined to 113 155 involving an 111 748 container enclosed building Dumpster or other Fire in a structure outside trash 154 218 other than a 112 119 receptacle fire building Self-propelled Natural vegetation 140- motor home or fire, not otherwise 141 136 13 141 recreational classified High Frequency High vehicle Odor or HazMat Recreational investigation, no 671 604 vehicle non self- 137 7 hazardous material propelled found Passenger vehicle 131- 311, fire, other than 135, 383 EMS 320- 112,520 motor home 138 324, Chimney or flue Nursing/Assi 700- 114 12 19,375 111 6 fire, confined to Alarms 799 sted Living chimney or flue Fires Biological hazard, Multi-Alarm Confined space 355 5 confirmed or 451 1 Road or 132 1 rescue suspected Freight Fire Brush, or brush Brush/Grass Water or ice 360- 36 and grass mixture 142 184 Fire > 100 142 0 related rescue 365 fire acres Multi- Family Chemical hazard Grass fire 143 123 421 15 Structure 111 1 (no spill or leak) Fire (2019 only) Chemical spill or High angle rescue 356 26 422 25 leak Extrication of Explosive, bomb Low Frequency Low victims from a 351, 8 removal (for bomb 471 4 building or 357 scare, use 721) equipment Flammable/comb Outside rubbish ustible gas or fire, not otherwise 150 59 410 14 liquid condition, classified other Gasoline or other Outside rubbish, 151 184 flammable liquid 411 258 trash or waste fire spill 370, Hazardous 371, Elevator rescue 353 351 868 condition, other 372, 400, 6 | P a g e 430, 431, 440- 445 460, Attempted 480- 8 burning or illegal 482 action other Oil or other Trench or below 354 1 combustible liquid 413 39 grade rescue spill Refrigeration leak 423 9 Toxic condition, 420 9 other Vehicle 352 272 Extrication Table 1 7 | P a g e Table 2 illustrates all of the incidents the District has responded to in the last five years in a heat map format.
