Low ground, storm runoff and river-country weather
After a heavy storm, water in low yards can stand for days. A post set in a hole that does not drain sits in wet clay, and wood posts can start to rot at the base far sooner than they would on a dry lot. Concrete crowns that shed water, gravel at the bottom of the hole and treated or rot-resistant posts all help.
Humidity near open water also grows mildew and algae on the shaded side of a fence. Storms can push strong wind across open yards by the water. If you are near a flood-prone area, ask your local office whether any rule limits solid fences or fills near the line. Fences that let water pass, such as open aluminum or chain link, are sometimes easier in those spots.
