Flagpoles in Wisconsin

Eder makes its flags and poles at Oak Creek, immediately south of Milwaukee, so a Wisconsin pole has a short journey to make.

Wind here. Wisconsin does not move on the wind map at all. Eder's chart puts the whole state at 90 mph, from the Illinois line through Milwaukee and Madison, up the Fox Valley to Green Bay, and across to Prairie du Chien and Platteville on the Mississippi. Where a permit set is drawn, the engineer works to the code the state adopts and the engineer's number for the address decides. Either way the number is mild, and it is not what decides a pole here. Winter is. Freezing rain lands on the flag and on the fittings at the top of the shaft at once, the footing has to reach below the frost line before it does anything structural, and any site facing Lake Michigan or the bay of Green Bay is sized as open ground however sheltered the street behind it looks.

• The Lake Michigan shore — From the Illinois line up through Racine, Milwaukee and Sheboygan to the Door Peninsula. The mapped figure is mild, Eder's 90 mph, and the exposure is not: there is nothing upwind of those sites but open water. Wall thickness follows the ground here rather than the map.
• Madison and the southern counties — The same mapped figure without the open water in front of it, which makes these the straightforward jobs in the state. What costs money is the hole rather than the shaft: the footing goes below a frost line that runs about four feet down here and deeper as you head north.
• The Fox Valley and the bay of Green Bay — Oshkosh, Appleton and Green Bay all read the same on the map. Inland sites in the valley are genuinely sheltered. Anything on the bay or on the Lake Winnebago shore is not, and takes a heavier shaft for it.
• The Driftless southwest and the north — The southwest corner along the Mississippi reads the same 90 mph on Eder's map as the rest of the state. The north carries the most ice. Stainless fittings and a rope run inside the pole behind a locking door are the difference between a flag you can lower in February and one you leave up.
