Gresham sits near the mouth of the Columbia River Gorge, where winter east winds push hard on fences. We set posts deeper, space them tighter and build to the city's 6-foot limit.
Gresham's fence rules fit on one page: 6 feet maximum, 4 feet in the front 10 feet of the property, and 3 feet (or open chain link) in the clear vision area at corners and driveways. Residential fences need no city sign-off, and barbed and electric wire are not allowed.
The weather is the harder part. NOAA notes that late-autumn and winter east winds out of the Gorge bring strong winds to the east side of the metro. A 6-foot solid fence acts like a sail. In Gresham we use deeper post holes, tighter post spacing and steel posts where the wind hits hardest.
