Using a sod cutter, cut away all the sod. Using a pick and a flat shovel also works but it just takes much longer.
You don't want the bocce balls gathering in the same corner every game. Using a laser level or large level, check to make sure the area is flat. Rake the dirt to lower areas or away from higher areas.
Use spray paint or chalk to mark the four corners of the court. For this project, the frame was 34 feet by 6 feet. A backyard bocce court can be any size you'd like, but regulation-size bocce ball courts are about 13 feet by 91 feet.
Using a circular saw or table saw, cut 2x6s to the desired frame size. Because synthetic wood material bends, consider doubling up the sides for a stronger bocce ball court.
The base rock needs to be about two to three inches deep. Load in the base rock into the court area and then tamp it down using a compactor.
If any areas are too low, add more decomposed granite to raise the area. If areas are too high, rake away the excess decomposed granite.
Local feed supply stores sell oyster-shell flour. Apply a thick coat (about one half of an inch of oyster-shell flour), then rake it until it's smooth. This material is known to increase the speed of bocce balls. Keep an extra bag on hand for maintaining the court.
