What does it take (and how) to build on a 'land conservation' parcel?
In Massachusetts, you cannot convert conservation land to commercial use unless you pay commercial taxes on it for FIVE years first.

So, for example, let's say it is 50 acres of land that would be worth $15 million on the open market, but its owner is willing to sell it to you for $1.5 million because it is conservation land. You want to build a house on the land (commercial activity). To do this, you must convert the land. To do this, you have to request a commercial assessment, then pay taxes on the assessed $15 million commercial value for FIVE years. At the end of that time the land will be converted and will no longer be conservation land and you can do what you want with it (assuming it is not a "wetland" or something, in which case the Federal government becomes important).

If you want utility service somewhere in the middle of nowhere, usually the developer (you) has to pay for it. That is what a "land developer" does.
