Table 14 shows the trip generation for the expanded Redwood City fuel station <br /> under this conservative scenario. <br /> Table 14 Approach #2: Expanded Redwood City Costco Gasoline Trip Generation Estimate Based on <br /> Highest 5 Island Site Observed—Weekday PM Peak Hour <br /> Existing Site 5 Island Expanded <br /> Trip Generation Trip Generation Difference <br /> In Out Total In Out Total In Out Total <br /> Total Trip Ends 200 200 400 250 250 500 50 50 100 <br /> Internal Trips(22%PM) (45) (45) (90) (55) (55) (110) (10) (10) (20) <br /> External Trips 155 155 310 195 195 390 40 40 80 <br /> Pass-by Trips(22%PM) (35) (35) (70) (40) (40) (80) (5) (5) (10) <br /> Diverted Trips(59%PM) (90) (90) (180) (115) (115) (230) (25) (25) (50) <br /> Net New Trips 30 30 60 40 40 80 10 10 20 <br /> As shown in Table 14, applying the highest trip generation observed at other Costco Gasoline <br /> facilities would result in a trip generation estimate for the expanded Redwood City Costco Gasoline <br /> fuel station of approximately 500 total trip ends and 80 net new trip ends during the weekday p.m. <br /> peak hour.This equates to an increase of 100 additional total trip ends and 20 additional net new trip <br /> ends over what the site is currently generating during the weekday p.m. peak hour. Given the level of <br /> activity and sales volume at the Scottsdale location in comparison to that the Redwood City, this is <br /> likely a conservative estimate for the additional number of trips that would be generated by <br /> proposed expansion. <br /> Kittelson&Associates,Inc.
