boox 98 V's'UO <br />concurrency analysis addresses project traffic occurring in the <br />peak hour and affecting the peak direction of impacted roadways. <br />According to ITE, the proposed use generates more volume in the <br />p.m. peak hour than in the a.m. peak hour. Therefore, the p.m. <br />peak hour was used in the transportation concurrency analysis. The <br />peak direction during the p.m. peak hour on SR AlA is southbound. <br />Given those conditions, the number of peak hour/peak season/peak <br />direction trips that would be generated by the most intense use of <br />the subject property under the existing zoning district was <br />calculated to be 1. This was determined by multiplying the total <br />number of units allowed under the existing zoning district (1) by <br />ITE's factor of 1.01 p.m. peak hour trips/unit, to determine the <br />total number of trips generated. <br />To determine the number of peak hour/peak season/peak direction <br />trips that would be generated by the most intense use of the <br />subject property under the requested zoning district, the total <br />number of units allowed under the proposed district (49) was <br />multiplied by ITE's factor of 1.01 p.m. peak hour trips/unit to <br />determine the total number of trips generated (49). Of these <br />trips, 65% (32) will be inbound and 35% (17) will be outbound. Of <br />the inbound trips, 57% or 18 will be southbound. 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 1 that would be.generated by the most <br />intense use of the subject property under the existing zoning <br />district (18 - 1 = 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 (50) 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 traf f is volumes; this is <br />updated daily based upon vesting associated with project approvals. <br />The traffic capacity for the segment of SR AIA most impacted by <br />this site is 1,310 trips (peak hour/peak season/peak direction) at <br />Level of Service (LOS) "D", while the existing traffic volume on <br />this segment of SR AlA is 285 trips (peak hour/peak season/ peak <br />direction). The additional 18 peak hour/peak season/peak direction <br />trips created by the most intense use of the subject property under <br />the proposed zoning district would increase the total peak <br />hour/peak season/peak direction trips for this segment of SR AlA to <br />approximately 303. <br />Based on the above analysis, staff determined that SR AlA and all <br />other impacted roads can accommodate the additional trips without <br />decreasing their existing levels of service. <br />The table below ide <br />associated with the <br />property, however, <br />Subdivision, a proje <br />acres.
