Minimum distance to House foundation
Been curious about how the minimum reasonably safe distance to plant a fairly large shade tree (i.e.: Red Maple, Northern Red Oak) from a house. Did some Googling and the few pages I found really addressing the subject gave a variety of answers (i.e.: half the crown width, 3/4'th the crown width, etc...).
From what I've read, the main 3 issues entail:
1.) Mechanical damage - roots get near a foundation or utility line, & exert pressure against it. Hence the disturbed sidewalks we see near some species of tree.
2.) Trees exaggerate the soil moisture fluctuations due to water uptake, causing problems when soils expand & contract, stressing structures by pressure.
3.) A branch could fall on a house, or the tree could topple.
On the other hand, if you want substantial shade to cut AC bills, you need a tall, bushy deciduous tree with a fairly dense crown near the house. A drive through a suburb shows some huge maple & oak trees quite close to houses.
So, what's YOUR take on minimum distances between houses & tree trunks? I realize it may vary with tree species, so how about we focus on some of the most popular yard shade trees & ornamentals. My suggestions:
1.) Red Maple.
2.) Northern Red Oak.
3.) River Birch.
4.) Bloodgood Japanese Maple.
5.) Japanese Weeping Cherry Tree.
6.) Green Giant Arborvitae (to get a conifer in there).
You may have some other suggestions; I just thought these'd be good to start with, and the thread a practical one.
