ORANGE CbUNTY, 1WRTH CAROLINA <br />response capability. These data indicate the streets (miles) and area served by the <br />current system. The maps show the street miles and percent of street miles covered <br />in time increments by a response unit responding to an emergency. The maps <br />present coverage in two-minute time increments. <br />The travel time maps only depict over-the-road travel, or running, times. A <br />review of dispatch information indicates that the average dispatch time (receipt of <br />a call to dispatch) from 2007 to 2009 is slightly less than two minutes. Dispatch time <br />and turn-out time should be added to these times for an estimate of total response <br />time. For example, afour-minute travel time response represents only part of the <br />response time to an incident. It is necessary to add dispatch time to the travel time <br />to establish the total response time. <br />The data associated with Maps 3 and 4 are shown in Exhibit 14. The exhibit <br />is composed of two parts. The top part of the exhibit shows travel time within each <br />time segment; the bottom part of the exhibit presents cumulative response, over <br />time. It is important to note that the map and associated data are intended to show <br />overall response in the County. <br />When considering the entire County fire and rescue system (and assuming <br />conservative road speeds), approximately 230 street miles (13 percent) within the <br />County are covered within two minutes travel time. Within six minutes travel time, <br />fire departments responding from stations cover 45.9 percent of the County's area <br />and 58.5 percent of the County's road miles; within eight minutes travel time, <br />approximately 78.8 percent of road miles are covered. <br />The Carrboro Fire Department and Chapel Hill Fire Department are able to <br />cover their entire response areas within four minutes travel time. <br />~} M1lIA CONSULTING GkOUP, INC. 20 <br />
