Wood Fence
Cedar and treated pine privacy fence and gates in Pocatello — what wood suits this climate, why gates fail first at the hinge post, and why every fence needs a permit.
Wood is the default privacy fence here for a reason: Pocatello's fence ordinance lists wood fabricated primarily as fencing material among the materials it treats as generally acceptable in residential zones, so a wood fence starts the permit conversation already inside the lines. The harder part is what this climate does to it. Southeast Idaho runs dry and bright through summer, then cycles hard through freeze and thaw. Wood moves with that — it shrinks in August, swells in a wet spring, and every fastener and post connection has to tolerate the movement rather than fight it. A solid wood panel is also the least forgiving shape you can put in front of wind and drifting snow, which is where most of the real failures start. Gates are where a wood fence fails first: a gate is a lever working on its hinge post every day, and a hinge post set no deeper than the line posts beside it is the most common reason a gate stops latching.
Wood Fence detailsBest for
In-town backyards where privacy is the whole point, and properties where the fence has to visually match a street of existing wood fence rather than stand out from it.
Watch out for
- Posts heaving over successive winters. Pocatello publishes a three-foot frost level in its design criteria, and a post set shallower than the ground actually freezes will be lifted and dropped until the fence line goes wavy.
- Wind loading against a solid panel. The city's published design wind speed is 115 mph per three-second gusts, and a six-foot privacy fence is effectively a sail — post spacing and post depth carry that load, not the pickets.
- Snow drifting and plow stacking against the run. A solid panel catches blowing snow and holds it; the city publishes a 45-pound ground snow load, and a fence line along a driveway or street edge can end up carrying far more than open ground does.
