Flagpoles in Missouri

Two metros at opposite ends of the state, the Capitol between them and the Ozarks under both.

Wind here. The wind map does not move across Missouri. Eder's chart puts the whole state at 90 mph, from the northwest corner around St. Joseph to Caruthersville in the Bootheel, roughly 375 miles, and every town on this page sits inside it. So the map is not what sizes a pole here. The ground is: deep glacial till north of the Missouri River, dolomite and limestone close under the Ozarks south of it, made ground along both big rivers. Exposure is the rest, because thunderstorm outflow crossing open country loads a shaft far harder than a sheltered street does. Missouri has no statewide building code either, so where a permit needs drawings the engineer works to whichever code your city or county has adopted, and we look it up for the address.

• North of the Missouri River — Eder's 90 mph, as across the whole state. Glacial till runs deep up here and the digging is usually easy, so what you pay for is the height you want rather than a heavier shaft.
• The two metros — Kansas City and St. Louis both sit at 90 mph on Eder's map, which is the easy part. Tight sites, historic-district review and footings over made ground or a parking deck are what actually cost money.
• The Ozarks and the southwest — The same 90 mph. Thin soil over dolomite, so the hole is the variable rather than the shaft, and a ridge top or a lake front behaves nothing like the valley town below it.
• The southeast and the Bootheel — The same 90 mph as the rest of Missouri. Flat alluvial ground with nothing upwind, so a wider footing and open-terrain sizing matter here more than wall thickness does.
