As shown in Tables IX -3 and IX -4, the cost and capacity for county roads have <br />been calculated based on typical roadway improvements. As shown in Table IX -5, the cost <br />per VMC for travel within IRC is approximately $314. This average cost per VMC figure is <br />used in the impact fee calculation to determine the total impact cost per unit of <br />development based on the vehicle -miles of travel consumed. For each vehicle -mile of travel <br />that is added to the road system, approximately $314 of roadway capacity is consumed. <br />Table IX -5 <br />Weighted Average Cost per Vehicle -Mile of Capacity Added <br />Source <br />County Roads <br />State Roads <br />Weighted Average <br />Cost per Lane <br />Mile(1) <br />$2,556,000 <br />$2,949,000 <br />$2,591,000 <br />Average VMC <br />Added per Lane <br />Mile(2) <br />8,085 <br />10,071 <br />8,255 <br />Cost per VMC(3) <br />$316.14 <br />$292.82 <br />$313.87 <br />(1) Source: Table IX -3 <br />(2) Source: Table IX -4 <br />(3) Cost per lane mile (Item 1) divided by average capacity added per lane mile (Item 2) <br />It is important to note that capacity projects eligible for impact fee funding include not only <br />new construction and Zane additions, but also associated intersection improvements, traffic <br />signalization, and other amenities and technology improvements that allow for additional <br />vehicle capacity. <br />Tindale -Oliver & Associates, Inc. <br />Indian River County <br />June 2014 114 Impact Fee Update Study <br />144 <br />
