Our education tax portion has been pretty steady. Where the massive increases have been is on the property side. During this period, the average home's market valuation has gone from $124,000 to $420,000 (ours from $166,000 to $506,000) but the mill rate is supposed to be adjusted so that the total tax revenues meet the cities need. They're not supposed to have a windfall from rising property values.
The real crush has been infrastructure. Funding for the construction of new roads and repairs to existing ones used to be funded moreso by the province. But, they cut municipal transfer payments drastically, and now we're playing catch-up on our infrastrucure.
Also, the rapid growth has really taken a toll on us. New development costs are subsidized by existing taxpayers, so the increase in new construction really hit budgets hard. There is some feeling that new construction builders should shoulder the entire cost, but that is a controversy.
When we looked at houses in Castlegar at spring break, most of the tax bills were in the $2K range. For us, that would be a $250 a month change.
