It was the population growth study. Basically the idea is that the schools we have now will be bursting at the seams for 10 years but then level off. They don't want to be stuck with giant empty high schools in places they don't need them. The growth is supposed to happen along the beltway and I think the district already owns land there for a school in the future...or something.
So basically the opposite of flattening the curve.
Personally, I wish they would split Humble ISD into two or three districts. It's too big. And I hope they're right about it leveling off because 4 years later that's not happening.
