No Notes: 1. Under the Extreme Maximum Assumptions,daily trips for the proposed 20-position GDF are assumed to double from existing levels for the 12-position GDF, per City of Redwood City staff,July 2012. This affects emissions associated with vehicle trips and vehicle queuing,as demonstrated in Tables B-2 and B-3. Note that the extreme maximum assumption that existing facility vehicle trips will double is extremely unlikely. This is because for this to occur,the proposed facility's weekday averaqe hourly vehicle trips would need to be 75%higher than the existing facility's weekday peak hour vehicle trips.
