Waste not, want not! Using old bunker sand as topdressing for fairways.

Even though the two fairway bunkers on the 1st hole are not being completely rebuilt, we will be replacing the sand. There are many different layers in these two bunkers ranging from bunker sand from 12 years ago to multiple layers of flood silt. When the new sand is installed the appearance of the bunkers will all be similar on this hole.
We will be using this sand as topdressing on the 1st fairway. We have had silt contaminated bunker sand tested in the past and it is acceptable as a fairway topdressing. Just trying to "kill two birds with one stone".
