 Community Transit has a fleet of double @-@ decker buses used on commuter routes from park and rides to Downtown Seattle , named the " Double Tall " in reference to the double tall cup size at Starbucks , a coffee chain founded and headquartered in Seattle . The Alexander Dennis Enviro500 was introduced during a one @-@ year pilot project in 2007 , on lease from Alexander Dennis for $ 15 @,@ 000 per month . The 42 @-@ foot @-@ long ( 13 m ) , 14 @-@ foot @-@ high ( 4 m ) Enviro500 seated 77 , with standing room for 20 additional passengers , replacing the capacity of the standard articulated buses used on the commuter routes in a smaller footprint . Prior to the end of the trial in 2008 , CT placed an order of 23 Enviro500s , scheduled to be delivered and put into service in 2010 ; the initial order was not fulfilled until 2011 , when manufacturing was moved to an ElDorado plant in Riverside , California to meet federal Buy America Act requirements . A second order of 17 Enviro500s , to replace older articulated buses , was made in 2013 and went into service in late 2015 .
