Figured I'd wait a while before logging back on this one. Think that most places want to do too much and would be better off doing the some tweaking and a lot of pruning first. Lot's of places to find alternative teeing grounds on many courses if you just look. This can give added value in that more teeing ground tends to improve conditioning! This sometimes happens just by the change in wear patterns for both carts and maintenance vehicles. Also different angles spice up the tee shots by asking the player to think a little more.
Of course committees tend to want to make a statement during their tenure. They better be sure they know what they are doing before they start cutting up the baby. Old overheads, photo's and plans can be a great aid in determining a good plan of action. Talk to the older members or people who have been playing there a long time. Even if you don't empower them in the decision, they know you care about history and hopefully about them.
If you take action , the best redo is one you couldn't pick out from the original holes. If your guys are good, the changes blend in seamlessly. Too often I have seen "good holes" from a golf perspective that just don't fit. The genre is different. To me that's a mortal sin in GCA. You know the work is good if no one could figure out what you did but just know it's better.
Sometimes it's enough to hire the right superintendent , who I find to be some of the most talented and dedicated professionals in any field of endeavor. They know which trees need to go , how to fix drainage issues and most mistakes if you listen to them.
