ULPT request: need to stop or divert the sale of my neighbors property

I currently have a view of the downtown of my town and down the hill to the bay of the lake that The town is situated on, from the kitchen and top floor bedroom of my house. Next door is a rancher/bungalow house with one level. It is in shambles. The neighbors own another property in the area and have decided to have this one demolished and sell the property. The listing is advertising that it is being sold as a property to have a 4plex built on it. There is a 4plex on the other side of my house and it is built right up to the property line and is taller than my house. If they do the same on this side, I will be surrounded by tall buildings using up as much space as they possibly can, blocking my view of the city. There is also a row of birch trees on their property that will most definitely be removed. I live at 62 degrees North so those Birch trees are not replaceable. It would take nearly 100 years for saplings to get close to the size they are now.

On top of all that, I am wrapping up a major renovation with the intent to sell in a few years. The loss of the view will significantly lower the value of my house.

Need tips. How do I stop this?
