Probably not the right forum
There is a line of big pines on my neighbors' property. The trees have been there since we moved here in 1989, planted by the original owners. The house has changed hands 3 times since 2016. Every family that moved hope to cut the trees, but it was too expensive. Well, today, they are getting cut down. The newest neighbor wants more space to park the several vehicles the family has. They built a carport next to the existing garage just recently. But I guess that's not enough. I don't know why people have to cut out the trees in the spring when the birds and other animals are nesting. It is bad enough that the trees are getting cut out, but it is cruel to destroy habitat when there are young creatures and animal parents trying to raise them. The neighbor up the street has wanted those trees gone for years. He wants every tree gone anywhere in his view. I'm pretty sure he has put a bug in every ear as the house changed hands.
The trees held the hillside in place. The tree hater has systematically cleared his side of the road of trees since he's lived there, and the result is more and more dirt and gravel washing down to my yard. I have r.r. ties lined up to direct the washout further down the edge of the yard. With the big pines gone, I predict that a lot of the new neighbor's yard is going to end up washing down my way. I told them the trees were planted there for a reason, but like everyone else on this street, they don't care about destroying the environment to make a parking place or increase the size of their yards.
The neighbor's daughter, who sold the house in 2016, bought a smaller house across town. She has planted over a dozen trees in her smaller yard there. I let my yard grow wild, and I think I will follow through with planting bushes in the part I don't use. I'm leaving soon for the day and I won't have to be here as they slaughter Nature.

The yard is 1/3 acre. I had 4 of the big trees trimmed 2 or 3 years ago. Cost $4500.00. The tree guy said if he had the trees he couldn't afford to get them trimmed. We both laughed, what can you do? I was holding my breath every time we had a storm come through, and I was less stressed since the trimming. The neighbor said awhile back that it was too expensive to get the pines cut down. When they put the carport up without cutting the trees, I thought they had worked around the trees.
We had to get a couple of smaller trees cut out in 1998 and 2012, after wind damage. We replaced both. Wishing you luck that the trees you are worried about hold up until you can tend to them. Maybe you can plant a couple of trees and get them established before you remove the fragile trees. 
Our new neighbor just had five lovely old maple trees completely cut down.
Pine trees, however …. now if they’re in good shape that’s one thing. But around here we’ve had spindly pine trees fall over in storms (due to shallow roots, I’m told). And when the homes were built decades ago, the homeowners planted the trees way too close to the house not completely understanding how big they’d eventually get. Roots get in the foundations or the pipes, etc. Pine needles clog up the gutters, etc.
I sure wouldn’t be too thrilled to see the trees removed for more vehicle parking, however.
We have 3 acres and 30+ large trees so we deal with tree issues a lot.
When my mother's friend across the street passed away they cut all the trees on her property - why?? I know that she loved the beautiful giant pine that predated building her house and the crab apple tree that she planted herself in her front yard. Both trees were cut down as well as any others on the property and my brother, who still lives in my parents' house, said that it's possible to see clear through the house and it's going to be hot in the summer with no shade. Ironically, the name of the street is "Sylvan," meaning "woodsy and rustic." 
With riding mowers, no less! In the summer there's a constant buzz of either mowers or chain saws.
We even have deer in these parts, not to mention bunnies, skunks, foxes, all manner of birds, and of course squirrels and chipmunks. We're actually invading their space and I respect that.
