4. Formula for Determining Number of Peak Hour/Peak Season/Peak Direction Trips Generated: Number of Units X P.M. Peak Hour Rate X Inbound P.M. Percentage X Inbound -Westbound Percentage (8 X 1.01 X .65 X .75 = 4) 5. Formula for Determining Number of Average Weekday Trips Generated: Number of Units X Average Weekday Rate (8 X 9.55 = 76) Proposed Zoning District 1. Use Identified in 5th Edition ITE Manual: Single -Family Residential 2. For Single -Family Units, in ITE Manual: a. Average Weekday Trip Ends: 9.55/unit b. P.M. Peak Hour Trip Ends: 1.01/unit c. Inbound (P.M. Peak Hour): 65% i. Westbound (P.M. Peak Hour): 75% ii. Eastbound (P.M. Peak Hour): 25% d. Outbound (P.M. Peak Hour): 35% i. Westbound (P.M. Peak Hour): 25% ii. Eastbound (P.M. Peak Hour): 75% 3. P.M. Peak Direction of 4th Street, from 43rd Avenue to 58th Avenue: Westbound 4. Formula for Determining Number of Peak Hour/Peak Season/Peak Direction Trips Generated: Number of Units X P.M. Peak Hour Rate X Inbound P.M. Percentage X Inbound -Westbound Percentage (120 X 1.01 X .65 X .75 = 59) (trip distribution based on a Modified Gravity Model) 5. Formula for Determining Number of Average Weekday Trips Generated: Number of Units X Average Weekday Rate (120 X 9.55 = 1146) 6. Traffic Capacity on this segment of 4th Street, at a Level of Service "D": 630 peak hour/peak season/peak direction trips 7. Existing Traffic volume on this segment of 4th Street: 97 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 zoning district is 76. This was determined by multiplying the 8 units (most intense use) by ITE's single-family residential factor of 9.55 Average Daily Trip Ends/unit. - The number of Average Weekday Trip Ends associated with the most intense use of the subject property under the proposed zoning district is 1,146. This was determined by multiplying the 120 units (most intense use), by ITE's single-family residential factor of 9.55 Average Daily Trip Ends/unit. 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 4th Street is westbound. 29 July 26, 1994 BOOK 92 _ FAA039. .
