The legislature encourages counties, in conjunction with cities, metropolitan planning organizations, and transit agencies in metropolitan areas to adopt goals for reducing the proportion of commuters who drive in single-occupant vehicles during peak commuting periods. Any county imposing a tax under this chapter must adopt such goals. In adopting these goals, counties shall consider at least the following:(1) Existing and anticipated levels of peak-period traffic congestion on roadways used by employees in commuting to work;(2) Existing and anticipated levels of transit and vanpool service and carpool programs available to and from the worksite;(3) Variations in employment density and employer size;(4) Availability and cost of parking; and(5) Consistency of the goals with the regional transportation plan.[ 1990 c 43 s 15.]
