I <br />JAN 1993 �ooK 88 Pn 414 <br />The number of Average Weekday Trip Ends associated with the most <br />intense use of the subject property under the existing zoning <br />3 district is 76. This was determined by multiplying the 8 units <br />(most intense use), by ITE's single-family residential factor of <br />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 />district is 1,127. This was determined by multiplying the 118 <br />units (most intense use), by ITE's single-family residential factor <br />Of 9.55 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 use. generates more volume in the <br />p.m. peak hour than in the a.m: peak hour. Theref6=e, the p.m. <br />peak hour was used in the transportation concurrency analysis. The <br />peak direction during the p.m. peak hour on 4th Street is <br />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 district was <br />calculated to be 5. This was determined by multiplying the total <br />number of units allowed (8) 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 district, the total <br />number of units allowed (118) under the proposed zoning was <br />multiplied by ITE's factor of 1.01 p.m. peak hour trips/unit; that <br />volume was then multiplied by the inbound trip factor of 0.65. The <br />result was 77, or 72 more than the 5 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 by.the proposed use were then assigned to roadways on the <br />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 4th Street adjacent to this <br />site is 630 trips (peak hour/peak season/peak direction) at a Level <br />of Service "D", while the existing traffic volume on this segment <br />of 4th Street is 103 trips (peak hour/peak season/peak direction). <br />The additional 77 peak hour/peak season/peak direction trips <br />created by the most intense use of the subject property under the <br />proposed zoning classification will increase the total peak <br />hour/peak season/peak direction trips for this segment of 4th <br />Street to approximately 180. <br />Based on staff analysis, it was determined that 4th Street and all <br />other impacted roads can accommodate the additional trips without <br />decreasing their existing levels of service. Impacted roads are <br />defined in the county's Land Development Regulations_ as roadway <br />segments which receive five percent (5%) or more daily project <br />traffic or fifty (50) or more daily project trips, whichever is <br />less. <br />The table below identifies each of the impacted roadway segments <br />associated with this proposed zoning classification.
