• Given those conditions, the number ofpeak hour/peak season/peak direction trips that would be generated bythe most intense use of the subject property under the existing land use designation was calculated to be 6.4. This was determinedbymultiplying the total number ofunits allowed (16) under the existing land use designation byITE 's factor of 1 01 p.m peak hour trips/unit, to determine the total number of trips generated. Of these trips, 64% of the 6.4 will be inbound and 36% will be outbound. Of the inbound trips, 62% or 4 will be northbound. To determine the number ofpeak hour/peak season/peak direction trips that would be generated bythe most intense use of the subject property under the proposed land use designation, the total number ofunits allowed under the proposed amendment (80) was multiplied by ITE 's factor of 1.01 p.m. peak hour trips/unit to determine the total number of trips generated (81) Ofthese trips, 64% will be inbound and 36% will be outbound. Of the inbound trips, 62% or 50 will be northbound Therefore the most intense use of the subject property under the proposed land use designation would generate 26 (32 - 6 = 26) more peak hour/peak season/peak direction traps than the 6 that would be generated bythe most intense use of the subject property under the existing land use designation. Using a modified gravitymodel 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 the Florida Department of Transportation Level ofService Handbook approved methodology. 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 82nd Avenue adjacent to this site is 820 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 82"d Avenue is 141 trips (peak hour/peak season/peak direction). The additional 32 peak hour/peak season/peak direction trips created bythe 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 82' Avenue to approximately 173. Based on the above analysis, staff determined that 82nd Avenue and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. Table 1 identifies each of the impacted roadway segments associated with the proposed land use designation. As indicated in Table 1, sufficient capacity is available on all of the segments to accommodate the projected traffic associated with the request.
