• <br />• <br />Indian River County I Impact Fee Update Study <br />To calculate a corresponding trip rate for the new tiers it was necessary to rely on <br />comparative ratios. As an example, consider the $42,156 annual income category. First, it <br />was determined that the average annual household VMT for this income level is 19,241 <br />miles. This figure was then compared to the overall average annual VMT per household in <br />the U.S. and normalized to the average of the $62,563 (24,053 miles) category to derive a <br />ratio of 0.800. Next, the normalized ratio was applied to the daily VMT for the average <br />single family housing unit size (Less than 1,500 sf) to generate a daily VMT of 41.36 for the <br />new tier, as shown in Table B-5. This daily VMT figure was then divided by the proposed <br />assessable trip length of 6.62 miles to obtain a typical trip:rate of 6.25 trips per day. <br />ie <br />Table - <br />65 <br />Trip Generation Rate by Single Family Land`Use, Tier <br />1 Estimation. of Trip Rate by <br />Tier <br />Tri Rate (1) <br />P <br />Assessable <br />Trip Length(2) <br />Daily <br />VMi3l <br />Ratio to <br />Mean(4): <br />Single Family <br />(Detached) <br />Single Family (Detached) <br />Less than 1,500 sf <br />Its 6.25 <br />6:62 <br />41.36 <br />Nib 800 <br />1,500 to 2,499 sf <br />7.81 <br />` . e 6.62 <br />51.70 <br />1.000 <br />2,500 sf or larger <br />920,m <br />m% 712 <br />60.90 <br />1.178 <br />(1) Daily VMT (Item 3) divided by assessable trip length (Iter 2)tfor each tiered single <br />family land use"'eategory <br />(2) Source: Table6=2 <br />(3) Ratio to the mean (Item 4),divided by the total daily VMT or#the 1,500 to 2,499 sf tier <br />for each ie ed sf single family land use category <br />(4) Source TabI4. <br />TableB=6 illustrates the�r.impactthat the incorporation of the trip generation rate tiers for <br />the singlfamily (detach d) land use ave on the County's calculated impact fee schedule. <br />4:414; <br />Net Impact Fee by Single Family Land Use Tier <br />Table B-6 <br />Impact of Tiering <br />Schedule <br />on Fee <br />Trip Rate (1) <br />Assessable <br />Trip Length <br />Daily VMT <br />Net Fee (2) <br />Single Family (Detached) <br />Less than 1,500 sf <br />6.25 <br />6.62 <br />41.36 <br />.' $3,491 <br />1,500 to 2,499 sf <br />7.81 <br />6.62 <br />51.70 <br />$4,354 <br />2,500 sf or larger <br />9.20 <br />6.62 <br />60.90 <br />$5,129 <br />(1) Source: Table B-5, Item 1 <br />(2) Source: Appendix E, Table E-1 <br />Tindale -Oliver & Associates, Inc. <br />January 2014 <br />Indian River County <br />B-3 Impact Fee Update Study <br />
