Portland's west side — Beaverton, Hillsboro, Cedar Mill — tends toward heavier clay that holds water through the winter, so we set posts deeper and use extra gravel at the base for drainage. Lake Oswego, West Linn, and Tualatin properties often deal with sloped lots, which changes how a fence line steps down a hill without gapping at the bottom. On the eastside — Gresham, Happy Valley, Milwaukie — we see more mature trees and root systems, so we scout the line for roots before we dig, not after. Wherever you are in the metro, the estimate visit includes a real look at your soil and slope, not just a tape measure.
