FCAT and the public school system have their own major problems. Lack of planning/budgeting just compound the issue.
The problem is more one of official shortsitedness combined with the typical government's voracious appetite for funds. I'll cite one concrete example we have a resource recovery plant built 15 years ago by floating a bond issue. This plant gererates electricity by burning trash. At the time it was designed to have four burners however only three were installed to save money. The thinking was that the fourth burner could be added later. Fast forward 15 years the plant is now over capacity. Due to changes in environmental and other regs the cost of refitting the plant with its intended fourth burner exceeds the cost of building a brand new stand alone plant. Remember we are still paying on the current plant which is now overcapacity.
schools are built on the same theories but many a brand new school is overcapacity in its first year open rather than being 15 years downline. These things are all supposed to be planned for the counties gobble up many thousands of impact fee dollars on every new house unfortunately most are wasted in political patronage rather than for the intended purpose.
