but how do other places handle this? I see plenty of parks where grass is accessible and not entirely gone (granted, a lot of those places don't have the most lush grass, but they have grass!). Is it just constant replanting?
We have The Domain in Sydney which hosts events and concerts too, so large crowds also are fine to some degree. I assume water and sun and fertiliser go a long way. But I've seen in other areas (and probably The Domain but I rarely go) they will put up temporary construction fences for regeneration when it needs a break and starts to show dirt.
In my experience, grass is only threatened if you have a lot of people in a very short time. Think concert or festival. Granted, NY/Manhattan has many more people than SF, but I don’t know if Central Park is that popular to reach those conditions? Golden Gate Park seems to cope fine indeed.
