The Brown County Board today (TUE) is scheduled to begin the process of possibly implementing a local option sales tax for transportation. Brown County commissioners unanimously approved a $10 per-vehicle annual wheelage tax last year that generates around $286,000 a year, but there is a pressing need for more funding to avoid falling behind in highway improvements. Current estimates show a $19-million shortfall in highway funding, and the proposed half-cent sales tax for Brown County would collect around $1.5-million a year dedicated to transportation projects. A referendum would not be required, but a public hearing must be held prior to adoption. In other business today the Brown County Board will consider entering into an agreement with Mn/DOT providing for limited use of certain trunk highways for snowmobile trail use. The board meeting starts at 9am in the county courthouse in New Ulm.
