I love that your pb is wanting to get done whatever work he can with the weather. Most of them use it as an excuse to do nothing. The waterfall looks great!
What I am doing now is I bought a bunch of 1x6x6' pressure treated boards which are the exact with length to fit under each section of fence with the ends notched to keep them in place. I hand cut all the grass as low as I can get it and use a portable jug saw to notch each end and placed them under the fence.
Can you show us a pic? i'm sorta a visual learner when it comes to pool stuff and need to see what you mean....

My grandfather only laid sod on 6-8 inches of topsoil when he did his sod for the business. He was nuts about the thickness of the topsoil also. Used to stick a yardstick in the soil as the guys raked and if he still saw red he would yell them to get back and add and redo. Sod needs a ton of water to stay moist to thicken. The extra good topsoil helps to keep the sod moist. Without moisture it produces more weeds. Sod is more susseptable to weeds vs seed grown grass. Don’t know why but it is.
Sod is great. U just have to prep properly. His topsoil always came from swamps that was then mixed with Pete humus and mushroom mulch. That is just how he did his topsoil. The dirt makes or brakes the sod and seed personally.
When i I did my yard my dad had me seed on 12-16 inches of topsoil. Ya I know nuts but my grass is Better than a pro baseball field. It never gets dry which helps to keep is green in low rain times.
Tipsoil Il is the key with sod.
Couple things you can do.
1 - seed it. I can tell you from experience, seed will adhere to the side of the hill. If you have streams of water rushing down that will wash it out but you need to direct the water so that doesn't happen. We had no issues at all with grass washing away. And we have a big grade and a big hill! We had 25 yards of dirt brought in to level our hill some but still ended up with a close to a 40 degree incline. They compacted it all with a tracked skidsteer and threw seed on the end of last year (by hand). This year the seed is awesome. It grew strong and deep and I can already use my tractor to cut it. I can only go straight up the hill and then back down and do the next strip though due to the incline. We had this all done at a cost of $3500. He said sod on the hill would be more problematic since it would be hard to pin it requiring a lot of pins and cutting would be worse since the sod would want to slip with that grade hill with any weight on it.
2 - sod. Sod is very easy to lay yourself. We got a ton of sod from home depot (probably 2 pallets) and put all of it down ourselves including on hilly parts in the entire pool area. You will need those wire landscaping staples that are like 8" long to pin the sod so it doesn't slide. We did some ground prep work like putting a couple bags of dirt first but that really isn't necessary. As long as you lay the sod tight to the ground and water, water, water, it will take.
3 - Terraces. Our landscaper talked about terracing the hill behind the pool. This was the most expensive option and we chose not to do it because of the price. I think it would have been something like $7500 total for 3 terraces top to bottom with enough room to get my tractor on each terrace. Not a do it yourself unless you have heavy equipment.
4 - retaining wall. We though about this but did not end up going with it. Over 4 feet (I think) is supposed to have an inspection since it is considered structural. We did build a couple of small walls within our pool area to augment the landscaping and they turned out really good. It is not hard at all as long as your base layer is done correctly.
FYI: Our final pool inspection failed because the area behind the pool was not properly graded and seeded to prevent erosion. #1 above was the solution to it and the inspector said it was great on the 2nd visit.
Also! Don't put ANY Grass under the fence line! OMG what a friggin' nightmare to cut the grass! You can't use a weedwacker the line chews up the bottom of the fence and gets wrapped around the posts. What I am doing now is I bought a bunch of 1x6x6' pressure treated boards which are the exact with length to fit under each section of fence with the ends notched to keep them in place. I hand cut all the grass as low as I can get it and use a portable jug saw to notch each end and placed them under the fence. I am not even close to being done but I can see already this is a GREAT solution!
If possible too don't put any grass within the pool area. When you cut it it's a mess in the pool. I have grass coming right up to the concrete deck and after cutting I use a blower to get rid of most of it but some always gets in the pool. I am looking at ripping out a lot of it and replacing with stones. The grass is ok accept for the parts that come right up to the deck. Cutting that part is what makes the mess.
You can see on the last pic the difference between having and not having the wood.
It looks like the entire fence (not just the posts) is almost touching the ground. Every install video I have watched said to install it so that it is two inches above the ground so you can cut the grass. Do you think that would make things easier? If yours is almost touching the ground as it appears, I can see how that would be a HUGE pain to deal with.
