b. P.M. Peak Hour Trip Ends: 1.01/unit <br />C. Inbound (P.M. Peak Hour): 65% <br />i. Westbound (P.M. Peak Hour): 80% <br />ii. Eastbound (P.M. Peak Hour): 20% <br />d. Outbound (P.M. Peak Hour): 35% <br />i. Westbound (P.M. Peak Hour): 20% <br />-ii. Eastbound (P.M. Peak Hour): 80% <br />3. Peak Direction of 26th Street, from 43rd Avenue to 58th <br />Avenue: Westbound <br />4. 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 X Inbound -Westbound Percentage <br />(147 X 1.01 X .65 X .80 = 77) <br />(trip distribution based on a Modified Gravity Model) <br />5. Formula for Determining Number of Average Weekday. Trips <br />Generated: Number of Units X Average Weekday Rate <br />(147 X 10.1 = 1,485) <br />6. Traffic Capacity on this segment of 26th Street, at a Level of <br />Service "D": 630 peak hour/peak season/peak direction trips <br />7. Existing Traffic volume on this segment of 26th Street: <br />173 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 land use <br />designation is 1,111. This was determined by multiplying the 110 <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 1,485. This was determined by multiplying the 147 <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 26th Street is <br />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 land use designation was <br />calculated to be 58. This was determined --by multiplying the total <br />number` of units allowed (110) under the existing land use <br />designation by ITE's factor of 1.01 p.m. peak hour trips/unit, to <br />determine the total number of trips generated. Of these trips, 65% <br />(72) will be inbound and 35% (39) will be outbound. Of the inbound <br />trips, 80% or 58 will be westbound. <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 proposed land use designation,the total <br />number of units allowed under the proposed amendment (147) 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 (148).
