Inspected the crawlspace of a 2007 built home. There is a sump and drain in the center of the crawlspace - drain is supposed to terminate at a drainage ditch adjacent to this neighborhood. Most of the homes in this small neighborhood have these drains however a few do not.

My question is why is the entire crawlspace covered with 2 to 4 inches of decomposed granite (DG) on top of the moisture barrier? Does this have anything to do with the drain system? The few homes without the drains have no DG in the crawlspace.
