Indian River County I Impact Fee Update Study <br /> In addition to looking at local data, a review of recently bid projects located throughout the <br /> state of Florida was conducted. As shown in Table C-15, a total of 52 projects (including the <br /> three projects in Indian River County) from 26 different counties estimated a weighted <br /> average cost per lane mile of$2.44 million per lane mile. <br /> Due to the lower construction costs observed between local county roads and statewide <br /> county improvements, and the small sample size of local state road improvements, the <br /> estimated state road construction cost was adjusted downward to provide a conservative <br /> estimate for use in the impact fee calculation. This adjustment was based on the ratio of <br /> local county roadway improvements to statewide county roadway improvements, which, as <br /> previously mentioned, is 83 percent. Therefore,the weighted average construction cost per <br /> lane mile for all state road improvements (including local and statewide data) was adjusted <br /> by 83 percent. Based on this analysis, a construction cost of$2.00 million per lane mile for <br /> urban-design state roadways was used to calculate the transportation impact fee for Indian <br /> River County. <br /> Table C-7 <br /> Construction Cost Adjustment—State Roads <br /> Construction Section Design Weighted <br /> Road Type Cost per Lane (2) Constr.Cost per <br /> Mile(l) Distribution Lane Mile(3) <br /> Urban Design $2,000,000 34%1 $680,000 <br /> Rural Design $1,660,0001 66%1 $1,096,000 <br /> Weighted Average Construction Cost per Lane Mile 1 $1,776,000 <br /> (1) Source:Table C-15.

This factor was determined through a review of the CEI-to-construction cost <br /> ratios for county road unit costs in previously completed impact fee studies throughout <br /> Florida. For county roadways, the CEI factors ranged from 4 percent to 14 percent, with a <br /> weighted average of 9 percent. For purposes of this update study, the CEI cost for county <br /> roads was calculated at 9 percent of the construction cost per lane mile (see Table C-16 for <br /> additional information). <br /> Tindale-Oliver&Associates, Inc.
