DE411 <br />c 8 1 <br />BOOK 88 F.,-7 <br />c X44 <br />6. Traffic Capacity on this segment of 49th Street, at a Level of <br />Service "D": 630 peak hour/peak season/peak direction trips <br />7. Existing Traffic volume on this segment of 49th Street: <br />153 peak hour/peak season/peak direction trips <br />The number of Average Weekday Trip Ends associated with the most <br />intense use of the subject property under the existing zoning <br />classification is 888. This was determined by multiplying the 93 <br />units (most intense use), by ITE's single-family residential factor <br />of 9.55 Average Daily Trip Ends/unit. <br />The number of Average Weekday Trip Ends associated with the most <br />intense use of the subject property under the proposed zoning <br />classification is 902. This was determined by multiplying the 154 <br />units (most intense use) by ITE's multiple -family residential <br />factor of 5.86 Average Daily Trip Ends/unit. <br />Since the county's transportation level of service is based on peak <br />hour/peak season/peak direction characteristics, the transportation <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 zoning classification generates more <br />volume in the p.m. peak hour than in the a.m. peak hour. <br />Therefore, the p.m. peak hour was used in the transportation <br />concurrency analysis. The peak direction during the p.m. peak hour <br />on 49th Street is westbound. <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 classification was <br />calculated to be 61. This was determined by multiplying the total <br />number of units allowed (93) under the existing zoning by ITE's <br />factor of 1.01 p.m. peak hour trips/unit, then taking 65% of that <br />total to ensure that only inbound trips were counted. <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 proposed zoning classification, the <br />total number.of units allowed (154) under the proposed zoning was <br />multiplied by ITE's factor of 0.55 p.m. peak hour trips/unit; that <br />volume was then multiplied by the inbound trip factor of 0.82. The <br />result was 69, or 8 more than the 61 that would be generated by the <br />most intense use of the subject property under the existing zoning. <br />Using a modified gravity model and a hand assignment, the trips <br />generated under the proposed zoning classification were then <br />assigned to roadways on the network. <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 49th Street adjacent to <br />this site is 630 trips (peak hour/peak season/peak direction) at a <br />Level of Service "D", while the existing traffic volume on this <br />segment of 49th Street is 153 trips (peak hour/peak season/peak <br />direction). The additional 69 peak hour/peak season/peak direction <br />trips created by the most intense use of the subject property under <br />the proposed zoning classification will increase the total peak <br />hour/peak season/peak direction trips for this segment of 49th <br />Street to approximately 222. <br />36 <br />
