Redwood City Costco Gasoline Expansion ProjE 7.A. - Page 262 <br /> August 20,2012 ruye�v <br /> data has been collected (including sites with significantly more activity than that <br /> of Redwood City) <br /> While the trip generation estimates at the lower end of the range of the remaining <br /> approaches (430 total weekday p.m. peak hour trips and 440 total weekday p.m. peak <br /> hour trips) are likely reasonable, to be conservative we recommend that the trip <br /> generation estimate developed using the highest observed trip generation at an existing 5 <br /> island location <br /> o While this is likely an overestimation of the trip generation impacts given the <br /> relative activity at that site compared with Redwood City, it will ensure the <br /> analysis is conservative and extremely defensible. <br /> The recommended trip generation estimate for the proposed Redwood City Costco <br /> Gasoline expansion project equates to an increase of 100 additional total trip ends and 20 <br /> additional net new trip ends over what the site is currently generating during the <br /> weekday p.m.peak hour. <br /> Five Island (20 Fueling Positionl Costco Gasoline Operations <br /> Data collected at the two existing 5 island (20 fueling position) Costco Gasoline facilities <br /> in the continental U.S. shows that even though one of those locations generates about 100 <br /> more total trip ends during the weekday p.m.peak hour,it has shorter average,maximum, <br /> and 95th percentile queues than those that occur at the Redwood City location under <br /> existing conditions. <br /> It also has significantly shorter vehicle wait times and less vehicle idling than the <br /> Redwood City location does currently. <br /> We trust this memorandum provides sufficient preliminary transportation data for Costco to <br /> continue discussions with the City on the proposed project and development review scoping.
