The board also began discussing whether to add a one-year transportation levy that would collect $ million to purchase buses that are needed to enlarge and modernize the fleet. The board could decide to add the transportation vehicle levy to the ballot at its Nov. 14 meeting. The measure would add about nine new buses to replace aging vehicles and provide additional buses that could be used to expand routes. Tahoma has not had a transportation vehicle levy since 2002. Morrow told the board that adding buses is only part of the solution to expanding bus routes, due to the continuing shortage of drivers for Tahoma and in the Puget Sound region.
