The NVTA is the agency that oversees the Transportation Sales Tax Expenditure Plan, if approved by the voters in June 2006. The NVTA may enter into contract, enact ordinances, issue bonds and may impose retail transactions and use tax ordinances to accomplish its goals as the “Local Transportation Authority and Improvement Act” agency.

The Napa Valley Transportation Authority (NVTA) is comprised of twelve members, two from each member jurisdiction, with each member having one vote (cities of American Canyon, Calistoga, Napa and St. Helena, the Town of Yountville and the County of Napa). NVTA duties will include three levels of responsibility: (1) day to day operational decisions, (2) amending the Transportation Sales Tax and (3) to add/change projects to the Transportation Sales Tax Expenditure Plan.
