S. Formula for Determining Number of Average Weekday Trips Generated: Total Acreage % Average Weekday Rate (101.8 acres 8 6.75/acre = 687) 6. Traffic Capacity on this segment of SR 60, at a Level of Service "C": 980 peak hour/peak season/peak direction trips 7. Total Segment Demand (existing volume + vested volume) on this segment of SR 60: 496 peak hour/peak season/peak direction trips The number of Average Weekday Trip Ends associated with the most intense use of the subject property under the existing land use designation is 5,858. This was determined by multiplying the 580 units (most intense use) by ITE's single-family residential factor of 10.1 Average Daily Trip Ends/unit. The number of Average Weekday Trip Ends associated with industrial development on Subject Property 1 is 687. This was determined by multiplying the 101.8 acres by ITE's industrial development fitted curve factor of 6.75 Average Daily Trip Ends/acre. Since the county's transportation level of service is based on peak hour/peak season/peak direction characteristics, the transportation concurrency analysis addresses project traffic occurring in the peak hour and affecting the peak -direction of impacted roadways. According to ITE, the proposed use generates more volume in the p.m. peak hour than in the a.m. peak hour. Therefore, the p.m. peak hour was used in the transportation concurrency analysis. The peak direction during the p.m. peak hour on SR 60 is eastbound. Given those conditions, 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 existing land use designation was calculated to be 194. This was determined by multiplying the total number of units allowed (580) under the existing land use designation by ITE's factor of 1.01 p.m. peak hour trips/unit, to determine the total number of trips generated. Of these trips, 65% (381) will be inbound and 35%r (205) will be outbound. Of the -inbound trips, Sit or 194 will be eastbound. To determine the number of peak hour/peak season/peak direction trips that would be generated by industrial development on Subject Property 1, the total site acreage (101.8) was multiplied by ITE's factor of 2.16 p.m. peak hour trips/acre to determine the total number of trips generated -(220). Of these trips, 50% (110) will be inbound and 50t (110) will be outbound. Of the inbound trips, sit or 56 will be eastbound. Therefore, industrial development Subject Property 1 would generate 138 (194 - 56 = 138) fewer peak hour/peak season/peak direction trips than the 194 that would be generated by the most intense use of the subject property under the existing land use designation. Using 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 (5k) 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 SR 60 adjacent to this site is 980 trips (peak hour/peak season/peak direction) at Level of Service (LOS) "C", while the Total Segment Demand (existing traffic volume + vested traffic volume) on this segment of SR 60 is 496 trips (peak hour/peak season/peak direction). The additional 56 peak hour/peak season/peak direction trips created by industrial development on Subject Property 1 would increase the Total Segment Demand peak hour/peak season/peak direction trips for this segment of SR 60 to approximately 552. Based on the above analysis, staff determined that SR 60 and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. The table below identifies each of the impacted roadway segments associated with industrial development on Subject Property 1. As indicated in this table, there is sufficient capacity in all of the segments to accommodate the projected traffic associated with the request. MARCH 18, 1997 95 moK DO P* 968
