Florida has this solved. Wood rots and breaks. Burial has flood issues. The solution is to install better poles. Most commonly, the poles are concrete with a square cross-section. Some are round concrete, spun while hardening to allow a hollow interior. Some are galvanized steel, with perhaps a decagonal cross section. One near my house is about 2 feet thick, with a label that says 50,000 pounds. These are not fragile. :-)
