When the three-member Port of Vancouver commission meets Tuesday to vote on the agency’s final 2010 budget, it will find projections for the highest net assets, highest port revenues, and lowest expenses the port has seen in five years. That good news comes even as total cargo tonnage has fallen back to below 2006 levels and the port faces a $23 million expense next year for its West Vancouver Freight Access project — nearly half of the port’s proposed $56.2 million annual budget.
