Due to the wet weather and continued cold temperatures, we are implementing the lift, clean and place rule. This allows you to clean your ball on any grassed area. You must mark your ball before lifting and cleaning it, and the ball must be placed back in the exact same spot—except when you are in the fairway, where you may place the ball within 6 inches of it original spot, no closer to the hole.

Official Ruling
14.1a Spot of Ball to Be Lifted and Replaced Must Be Marked
Before lifting a ball under a Rule requiring the ball to be replaced on its original spot, the player must mark the spot which means to:
Place a ball-marker right behind or right next to the ball, or
Hold a club on the ground right behind or right next to the ball.
If the spot is marked with a ball-marker, after replacing the ball the player must remove the ball-marker before making a stroke.
If the player lifts the ball without marking its spot, marks its spot in a wrong way or makes a stroke with a ball-marker left in place, the player gets one penalty stroke.
When a ball is lifted to take relief under a Rule, the player is not required to mark the spot before lifting the ball.
