am 93 PAGE 217 <br />trips, 65% (95) will be inbound and 35% (51) will be outbound. Of <br />the inbound trips, 75% or 71 will be westbound. Therefore, the <br />most intense use of the subject property under the proposed zoning <br />district would generate 17 more peak hour/peak season/peak <br />direction trips than the 54 that would be generated by the most <br />intense use of the subject property under the existing zoning <br />district (71 - 54 = 17). <br />Using a modified gravity model and a hand assignment, the peak <br />hour/peak season/peak direction trips generated by the proposed use <br />were then assigned to impacted roads on the network. Impacted <br />roads are defined in section 910.09(4)(b)3 of the county's LDRs as <br />roadway segments which receive five percent (5%) or more of the <br />project traffic or fifty (50) or more of the project trips, <br />whichever is less. <br />Capacities for all roadway segments in Indian River County are <br />calculated and updated annually, utilizing the latest and best <br />available peak season traffic characteristics and applying Appendix <br />G methodology as set forth- in the Florida Department of <br />Transportation Level of Service Manual. Available capacity is the <br />total capacity less existing and -committed traffic volumes; this is <br />updated daily based upon vesting associated with project approvals. <br />The traffic capacity for the segment of Indian River Boulevard <br />adjacent to this site is 1,770 trips (peak hour/peak season/peak <br />direction) at Level of Service (LOS) "D", while the existing <br />traffic volume on this segment of Indian River Boulevard is 320 <br />trips (peak hour/peak season/peak direction). The additional 71 <br />peak hour/peak season/peak direction trips created by the most <br />intense use of the subject property under the proposed zoning <br />district would increase the total peak hour/peak season/peak <br />direction trips for this segment of Indian River Boulevard to <br />approximately 391. <br />Based on the above analysis, staff determined that Indian River <br />Boulevard and all other impacted roads can accommodate the <br />additional trips without decreasing their existing levels of <br />service. <br />The table below identifies each of the impacted roadway segments <br />associated with this proposed zoning classification. As indicated <br />in this table, there is sufficient capacity in all of the segments <br />to accommodate the projected traffic associated with the request. <br />TRAFFIC CONCURRENCY DETERMINATION <br />Impacted Road Segments <br />(peak hour/peak season/peak direction) <br />Roadway <br />Segment <br />Road <br />From <br />TO <br />segment <br />Capacity <br />LOS "D" <br />1030N <br />SR AlA <br />17th Street <br />SR 60 <br />1,060 <br />1030E <br />SR AlA <br />17th Street <br />SR 60 <br />1,060 <br />1040N <br />SR AlA <br />SR 60 - <br />N.
