What should be done by my thoughts:
1. Move the fairway bunkers down 40-50 yards. Not in play for me, let alone tour pros who carry the ball 40 yards farther. Raise the green 5 feet and create a horizon to the ocean.
2. Shift the fairway left 10-15 yards and expand the fairway bunker. Would eliminate some of the hackers slicing their ball into players hitting their third shot into 1.
3. Remove the left bunker and expand the green to the edge of the canyon. It would add some pinnable locations to a green that gets a ton of ball marks because it's a wedge for everyone.
4. Shift the fairway left to bring the canyon into play. Expand and move the fairway bunker down. Possible: add a "Farmers Insurance" tee near the 3rd tee (not in play for the public, would create slow play issues), which would create a dogleg left Cape hole with an intimidating tee shot.
5. Better define the landing area by expanding the right hand bunker rather than the out of play circle there now. Flatten the green to allow more pinnable locations (very steep now.)
6. Nothing, except perhaps slightly flattening the green and/or shifting it slightly left.
7. Potential to be a great hole. Flatten the tee box, it's somewhat uneven. Shift the fairway left to actually bring the canyon in to play for more than a violent snap hook. Flatten the fairway slightly. Push the green up the hill 20-25 yards, if possible. Turns a tough hole into a memorable beast.
8. Move the fairway bunker down 25-30 yards. Widen the fairway to 45-50 yards from the current 25 yards most of the way.
9. Add some fairway bunkers to make the tee shot tougher, it's too easy now for a reachable par 5. It's too short for the pros right now as a 5 but that is ok, it's a 4.5 for them and a 5 for the rest of us.
10. Widen the fairway 10 paces. Otherwise, a good par 4 typically into the wind.
11. Move the fairway bunker down 40 yards or add a second and third fairway bunker on the right. Right now, there is not enough of a penalty for bailing out away from the canyon.
12. Nothing, except maybe raising the area right of the green and putting the back tee into play more often. Would play well as a 220 yard par 3 requiring a running draw rather than the 5-7 iron right now.
13. Nothing. One of the few holes where the fairway bunkers are correctly placed based on the proper teeing grounds for the player.
14. See #9, tee shot is uninteresting for a reachable par 5 and the bunkers are not in play for the proper tee. Deepen the greenside bunkers to penalize the errant approach in 2.
15. Fairway bunker needs to be repositioned, otherwise no changes. Not much room for 15 & 16 to make many changes.
16. Shorten to 315 from back and 280-290 from white. Right now it's a very indifferent 3 wood sand wedge with no reason for anything else. Add a top-shot bunker 40-50 yards short of the green. Remove the current bunker, it's useless and not in play.
17. Expand the green to include some pin locations which bring the water into play. A somewhat dull par 3 but as with 15 & 16 there is not much space to work with.
18. Build up the hill at the start of the fairway 5-10' to create a true blind/Alps tee shot. The 2nd/3rd shot is very anticlimactic but this probably the flattest spot on the golf course. Perhaps add some fairway bunkers in the layup area to make the eye wander.
I personally think the North could be a spectacular golf course with a few touches. Right now it feels like unused potential, I very much enjoy playing there but always think of new things to do.
