We use temporary spray chalk made for turf fields. Our stadium manager actually bought it for us. If you don’t go crazy with the size of the marks, it doesn’t interfere with other activities. It’s completely gone with a heavy rain. If it doesn’t rain at all, we can usually still see the marks just barely well enough to redo them without measuring again each week. It comes in a variety of colors. We use orange and just put small ticks on the 4s. No one has ever complained about it being there, even when it’s still visible during varsity football games (which it’s usually pretty well worn away by the end of the game).
There are several brands, but we use this one:
