It sounds more like assisted living. A CCRC I was referencing is when you go in healthy and if you ever need additional services of assisted living or long term care they are provided at no additional cost.
I feel for you. Unfortunately you probably will have a difficult time convincing him to go there. My mom who is in her 90s and her two sisters in their 80s will not even consider independent or assistant living. My cousin and I always hear only old people are there. We are not going there. We can live cheaper at home. As they get older they cannot understand their diminished capacity.
I think many people can't afford such a place, but also remember their grandparents and parents living at home the entire time. What I thing gets forgotten (but that I'm trying to stay aware of) is my fathers side grandparents both died ~ 60. They were independent, then dead. My mothers side grandmother had 4 kids, 2 lived next door, one to the left, one to the right, and one lived with her till she died. She had 3 adults plus their kids to help take care of her as she aged. My mom had 2 kids and we live in the same area. We all took care of my dad till he passed, including my mom's brothers, and us kids. He was much older than my mom though. My mom is now aging, and it's me and my sister and BIL, but again, 3 people plus friends can take care of her. She doesn't really have to move.
Some people don't realize they need other plans. I also notice that as people get older they get "fixed" in "how life was" back when they were kids, or maybe in their 20s. Heck, I have to keep reminding myself when thinking about schools or college that my experience is now probably more out of date than many cause I don't have kids. What high school was like in the 90s or college in the aughts probably isn't representative of today (for example). If you aren't in touch with the changes over time, you will insist, against all evidence, that "my parents didn't need to move so why would I" when almost everything might be different.
And I see it with my mom - a family a few miles away from us used to be real old school neighbors with my grandmother. They all knew each other, they'd get together, they'd help out with stuff. Now one of them had a total loss house fire. My mom was saying "we have to go over there and bring them food or offer them a place to stay". We were like - Who even are these people? We last saw them at a relatives funeral a couple years ago. My mom couldn't get in touch with anyone, my sister found someone on Facebook. We then found out the person my mom knew died in Feb. We had no idea. They had everything figured out for the now homeless person within their family and didn't need or want anything from us - mostly cause anyone on their family who knew who we were had died. But my mom still has this idea that the relationship from 45 years ago holds today with no upkeep...
People's grandkids don't inherit friend or relative relationships by osmosis. Things won't be "the same" if you don't work to keep it the same, and many don't for whatever reason. I just think people don't want to update their concept of themselves and the world as time goes on.
Tangent: I also think that more cultural things changed too - I hear all sorts of stories about how my grandparents would go for summers to different relatives houses, how my oldest uncle would send my 10 year older cousins to my grandparents for summers etc etc. You know how often I got sent to my oldest Uncle's house? Once when I was home from college with my teenage sister. Of course we're not as close with that side of the family... Now my cousin's has brought his kids up to see me 3 times, I think once was for his dad's funeral. I try and go down and see them, but scheduling is complicated - the kids are always busy on weekends with activities, his wife is getting an MBA, etc etc. Summer isn't a months long vacation for kids anymore to send them off to relatives for a month, and kids seem to need way more supervision too - helicopter parenting etc. Plus it seems like people that would have just died in the past are alive, but need a lot more elder care than a generation or two ago, so the adults are at best split in time taking people to doctors visits, cancer treatment, their own doctors (Cause it seems like by 40 you just get infinite specialists now - though we get to often make it to the early 80s vs dying at 60 so yay I guess) and don't have a bunch of "free time" to spend on kids of their relatives to swap summers around and have strong relationships.
Tangent sort of over: So people may think their relatives are going to come take care of them in place of assisted living, but it's often a fantasy they refuse to be disabused of. And at least one reason is they didn't live their 30s-60s deep in their relatives kids lives and they didn't have 4+ kids themselves so there's no relatives coming...
