Ground Under Repair is considered an "Abnormal Ground Condition. " An "abnormal ground condition" is any casual water, ground under repair or hole, cast or runway on the course. Ground Under Repair on hole number 15 at Fieldstone is marked by white lines (due to excessive divots).
Remember the rule provides that you "may take relief" but you are not required (unless under committee decision). If you have a good lie think twice before taking relief because your drop may result in a worse lie.
The usga interpretation reads:
25-1. Abnormal Ground Conditions
Interference by an abnormal ground condition occurs when a ball lies in or touches the condition or when the condition interferes with the player's stance or the area of his intended swing. If the player's ball lies on the putting green, interference also occurs if an abnormal ground condition on the putting green intervenes on his line of putt. Otherwise, intervention on the line of play is not, of itself, interference under this Rule.
Note: The Committee may make a Local Rule stating that interference by an abnormal ground condition with a player's stance is deemed not to be, of itself, interference under this Rule.
Except when the ball is in a water hazard or a lateral water hazard, a player may take relief from interference by an abnormal ground condition as follows:
(i)Through the Green: If the ball lies through the green, the player must lift the ball and drop it, without penalty, within one club-length of and not nearer the hole than the nearest point of relief. The nearest point of relief must not be in a hazard or on a putting green. When the ball is dropped within one club-length of the nearest point of relief, the ball must first strike a part of the course at a spot that avoids interference by the condition and is not in a hazard and not on a putting green.
