Bill We really don't have anything which would show what's there, or what might happen. This project is a ways off until funds are raised and there is some formal entity undertaking the work. Next time I'm out there I'll grab some images to post.
Safe to say that the intent will be to bring bunkers back to their original depth and shapes, possibly shifting a few; bring desert areas back into play by removing trees which have funneled the shots; and restore lagoons and "creeks". We also have talked about restoring the desert to remove trash and debris the City has actually dumped palm branches and stuff throughout the course in places. Some tees will be added.
Regarding the lagoons/creeks, my fond memories were the continual trickle of water across Nos. 6, 7, 13, 14, and 15 all of this has been piped to "speed up play". One approach we discussed was shifting the crossings from their original pathways to more distant (from the tee) spots where the water would play havoc more with the long hitter than the average, daily player. This would offer some heroic decision-making from the tee that is not there so much without the water.
I've always thought that the par-5s needed work. No. 1 is a great opener OK. But, you're right. No. 10 is weak as it duplicates No. 1 No. 10 needs a stronger hazard at the green and then an open area left of the green. If you look closely you can see where trees have encroached the option to play well left and come in from the far outside. No. 9 has the blind lake from the tee it's a problematic hole No. 15 needs hazards brought into play, possible with some desert areas crossing the fairway.
All this is preliminary thinking. Until we dive into the work there is only enthusiasm
