Traffic Capacity on this segment of SR 60, at a Level of <br />Service "D": 3,110 peak hour/peak season/peak direction trips <br />7. Total Segment Demand (existing volume + vested volume) on this <br />segment of SR 60: 2,065 peak hour/peak season/peak direction <br />trips <br />The number of Average Weekday Trip Ends associated with the most <br />intense use of the subject property under the existing land use <br />designation is 1,677. This was determined by multiplying the 166 <br />units (most intense use) by ITE's single-family residential factor <br />of 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 land use <br />designation is 2,444. This was determined by multiplying the 242 <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 />NOVEMBER 12, 1996 54 <br />s � r <br />
