This is an unfortunate result of how California deals with property tax. In many places the property taxes go mostly/all to the school district and the city/county. When property values go up a lot there is no reason that they have to keep the property tax at the same rate. They could lower it to keep the expenditures the same. In some places they even just figure out a budget for the year and then set the property tax accordingly.

California property tax mostly goes to the state and it funds schools by giving money back to the local districts (except about 60 really rich ones that opted out!) based on the number of student days/school. I'm not really sure, but I think that prop 13 passed after the state started taking property tax money. That would make sense as people like to have control of how there taxes are spent.
