To determine the number of peak hour/peak season/peak direction trips that would be generated by the most intense use of the subject property under the proposed land use designation, the total square footage of shopping center allowed under the proposed amendment (21,000) was multiplied by ITE's factor of 10.87 p.m. peak hour trips/1,000 square feet to determine the total number of trips generated (228). Of these trips, 49% or 110 trips are new trips, which are due to the proposed land use designation. From the new trips, 48% (53) will be inbound and 52% (57) will be outbound. Of the inbound trips, 65% or 34 trips will originate from the east of the subject property. Therefore, the most intense use of the subject property under the proposed land use designation would generate 27 (34 - 7 = 27) more peak hour/peak season/peak direction trips than the 7 that would be generated by the most intense use of the subject property under the existing land use designation. Using a modified gravity model and a hand assignment, the peak hour/peak season/peak direction trips generated by the proposed use were then assigned to impacted roads on the network. Impacted roads are defined in section 910.09(4)(b)3 of the county's LDRs as roadway segments which receive five percent (5%) or more of the project traffic or fifty (50) or more of the project trips, whichever is less. Capacities for all roadway segments in Indian River County are calculated and updated annually, utilizing the latest and best available peak season traffic characteristics and applying Appendix G methodology as set forth in the Florida Department of Transportation Level of Service Manual. Available capacity is the total capacity less existing and committed (vested) traffic volumes; this is updated daily based upon vesting associated with project approvals. The traffic capacity for the segment of 45`h Street adjacent to this site is 760 trips (peak hour/peak season/peak direction) at Level of Service (LOS) "D," while the Total Segment Demand (existing traffic volume + vested traffic volume) on this segment of 45th Street is 352 trips (peak hour/peak season/peak direction). The additional 34 peak hour/peak season/peak direction trips created by the most intense use of the subject property under the proposed amendment would increase the Total Segment Demand peak hour/peak season/peak direction trips for this segment of 451h Street to approximately 386. Based on the above analysis, staff determined that 45`h Street and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. As part of the concurrency review process, the applicant has submitted a Traffic Impact Analysis (TTA). The county's Traffic Engineering Division has reviewed and approved that TIA. Information from the applicant's TIA is displayed in table 2. This table identifies each of the impacted roadway segments associated with the proposed land use designation. As indicated in table 2, sufficient capacity is available in all of the segments to accommodate the projected traffic associated with the request. April 28, 1998
