Patrol the court daily to remove any debris that might have ended up there, and dispose of it properly.
Rake the sand to bring up any sharp objects and trash. Place these in a plastic bag for disposal. Include the removal of any sharp rocks or stones that could cut players' bare feet. Regular raking will also help keep the sand dry and soft.
Even out low spots in the sand with a rake and shovel. Activity is usually very intense at the net and the sand there often gets kicked away, leaving a trench. Fill this in with sand from higher spots on the court.
Check the padding on poles and other structures that players could run into. Repair or replace as needed.
Clear trash, obstructions and any other debris from a 3- to 4-foot-wide perimeter around the court. If grass grows inside this perimeter, keep it mowed short
Look for wear at points on wooden posts where net anchors are attached. Repair or replace worn posts
