Cheyenne is Wyoming's capital at 6,062 feet elevation — the windiest major US city (12.4 mph average, 50+ mph gusts) and served by Black Hills Energy for BOTH electric and gas (single utility). Altitude derates equipment capacity roughly 15% vs. sea-level specs.
Two factors dominate fence installation in Cheyenne: the 30-inch frost depth requires posts at 36–42 inches, and the wind is the more unusual challenge. At an average of 12.4 mph annually — the highest of any major US city — with gusts regularly above 50 mph and occasional storm gusts above 80 mph, fence posts and panel hardware must be specified for sustained high-wind loads. Solid privacy fence panels act as sails in these conditions; standard hardware spacing that works in a sheltered suburban environment will allow the fence to rack and lean in Cheyenne's wind within a few years. A fence contractor with specific Cheyenne experience understands this — contractors from lower-wind markets often don't.
Call Black Hills Energy (1-888-890-5554) and dial 811 at least 3 business days before any post-hole excavation. Black Hills serves both gas and electric infrastructure throughout Cheyenne's established neighbourhoods, and 36–42-inch post holes go deep enough to reach buried service lines.

Common questions about Cheyenne, WY fence permits
How deep should fence posts be in Cheyenne WY?
Posts in concrete at 36–42 inches — below the 30-inch frost depth with margin. But in Cheyenne, wind is as important as frost: 50+ mph gusts create large lateral loads on solid privacy fences. Posts and hardware must be rated for sustained high wind, not just the frost depth.

Yes. Apply at cheyennecity.org or call (307) 637-6265.
