Formula for Determining Number of Peak Hour/Peak Season/Peak <br />Direction Trips Generated: Number of Units X P.M. Peak Hour <br />Rate X Inbound P.M. Percentage (2 X 1.01 X 0.65 = 1) <br />4. Formula for Determining Number of Average Weekday Trips <br />Generated: Number of Units X Average Weekday Rate <br />(2 X 9.55 = 19) <br />Proposed Zonina District <br />1. Residential Use Identified in 5th Edition ITE Manual: <br />Condominium/Multiple-Family <br />2. For Condominium/Multiple-Family Units, in ITE Manual: <br />a. Average Weekday Trip Ends: 9.55/unit <br />b. P.M. Peak Hour Trip Ends: 0.55/unit <br />c. Inbound (P.M. Peak Hour): 66% <br />d. Outbound (P.M. Peak Hour): 34% <br />3. Formula for Determining Number of Peak Hour/Peak Season/Peak <br />Direction Trips Generated: Number of Units X P.M. Peak Hour <br />Rate X Inbound P.M. Percentage (24 X 0.55 X 0.66 = 9) <br />(trip distribution based on a Modified Gravity Model) <br />4. Formula for Determining Number of Average Weekday Trips <br />Generated: Number of Units X Average Weekday Rate <br />(24 X 5.86 = 141) <br />5. Peak Direction of C.R. 510 from S.R. AlA to U.S. 1: Eastbound <br />6. Traffic Capacity on this segment of C.R. 510, at a Level of <br />Service "D": 630 peak hour/peak season/peak direction trips <br />7. Existing Traffic volume on this segment of C.R. 510: <br />346 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 />district is 19. This was determined by multiplying the 2 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 Tfip Ends associated with the most <br />intense use of the subject property under the proposed zoning <br />district is 141. This was determined by multiplying the 24 units <br />(most intense use) by ITE's multiple -family residential factor of <br />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 -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 C.R. 510 is eastbound. <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 (2) 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 />27 <br />CNK �. �yg� BOOK 89 PAGFTO <br />
