BOOK 94 PALE. 7b <br />The number of Average Weekday Trip Ends associated with the most <br />intense use of the subject property under the existing zoning <br />district is 20. This was determined by multiplying the 2 units <br />(most intense use) by ITE's single-family residential factor of <br />10.1 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 1,071. This was determined by multiplying the 106 <br />units (most intense use), by ITE's single-family residential factor <br />Of 10.1 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. 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 S.R. 60 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 district was <br />calculated to be 1. This was determined by multiplying the total <br />number of units allowed under the existing zoning district (2) by <br />ITE's factor of 1.01 p.m. peak hour trips/unit, to determine the <br />total number of trips generated. Of these trips, 65% will be <br />inbound and 35% will be outbound. Of the inbound trips, 75% will <br />be southbound. <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 (106) 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 (107). Of these <br />trips, 65% (70) will be inbound and 35% (37) will be outbound. Of <br />the inbound trips, 60%, or 42, will be westbound. Therefore, the <br />most intense use of the subject property under the proposed zoning <br />district would generate 41 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 (42 = 1 = 41). <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 (5%) 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 traffic volumes; this is <br />updated daily based upon vesting associated with project approvals. <br />APRIL, 4, 1995 36 <br />
