24 ORANGE COUNTY, AbRTH CAROLINA response capability. These data indicate the streets (miles) and area served by the current system. The maps show the street miles and percent of street miles covered in time increments by a response unit responding to an emergency. The maps present coverage irr two - minute time increments. The travel time maps only depict over - .the =road -travel, or running, times. A review of dispatch information indicates that the average dispatch time - (receipt of a call to dispatchi) from 20x7 to 2009 -is slightly less than two minutes. Dispatch time and turn -out time should be added to these times for- an estimate of total response time. For example, a four- minute travel time response - represents only part of the response time to -an- incident. It is necessary to add dispatch time to-the travel time to establish the total response time. The data associated with Maps 3 -and-4 are shown in Exhibit 14. The exhibit is composed of two-parts. The top part of the exhibit shows travel time within each time segment; the bottom part of the exhibit presents cumulative response,_ over time. It is important to note -that the map and associated data -are intended-to show overall response in the County. When considering the entire County fire and rescue system (and assuming conservative road speeds), approximately 230 street miles (13 percent) within the County are covered within two minutes travel time. Within six minutes travel time, fire departments responding from stations cover 45.9 percent of the - County's area and 58.5 percent of the County's road miles; within eight minutes travel time, approximately 78.8 - percent of road miles are covered. The Carrboro Fire Department and Chapel Hill Fire Department are able to cover their entire response areas within four minutes travel time. * ADM CONSULTING CROUP, INC. 20
