Neighbor's Cypress Roots Damaging Driveway and Foundation

Question: Cypress roots destroyed driveway, now cracking slab and garage. How to stop without killing tree?

Answer

Trench 2 ft deep along property line/house between tree and structures. Cut up to ⅓ of roots safely—conifers tolerate root pruning better than hardwoods. Expect some dieback on cut side, but tree recovers. Rent a trencher for efficiency.
