Personally, I'm far less concerned about my lawn than I am about the trees around my house. By my own guestimate, there are at least 3 BIG trees that would destroy our house and kill us should they ever collaspe. It isn't so bad this year since we have mostly been having a pretty mild summer (on top of a very wet spring / early summer), but in the past several years, those trees have been showing obvious signs of heat & drought stress. I try to do what I can to mitigate the effects of those heat and drought stress, there is only so much I can do.

My neighbour from across the street has an even BIGGER tree, and he doesn't give a damn about its well being at all. If any of that tree's big branches snap on him, it is not gonna be pretty.

I came across this scene while I was running errands in July, and this is precisely the kind of thing that I would want to avoid:

Unfortunately, I have been seeing this sort of thing around the neighbourhood every now and then in the past couple of years.

My property is surrounded by trees and we've had a lot of conversations with the District about them. They've actually been fairly open to conversation, but they will do anything to avoid coming out and doing work at their own cost. But go figure, they agreed to give me a permit so I could trim and remove THEIR trees at my own cost (was totally worth it).

So if it's that worrisome, might be worth getting a tree company to take a look, give you an assessement and as estimate, and take to the city to convince them the trees are a risk. Best case is they take care of it. Next option is they let you do it at your own cost. Or worst case, none of the above, but you have nothing to lose. And at least then, the city is "on notice" that if something happens in the future, they'll risk being negligent.
