With a Moderate Soil Corrosivity Index, use hot-dip galvanized or stainless steel fasteners to prevent rust streaks. Given the Slight to Moderate termite risk, pressure-treated wood, composite, or metal posts are recommended. Material compatibility prevents premature degradation from soil chemistry and insect activity.

Posts require a minimum 42-inch footing depth, set fully below the frost line. The IRC requires this to prevent frost heave, where soil expansion lifts posts. In Downtown Spearfish, shallow footings lead to racked gates and failed post anchors after winter.

Spearfish zoning limits fence height to 4 feet in front yards and 6 feet in rear. A 0-foot setback allows building on the property line.

The 115 MPH V-ult wind speed rating dictates structural design. This requires closer post spacing (often 6 feet on-center), concrete footings sized for overturning moments, and ASCE 7-22-compliant brackets. This engineering ensures the fence survives peak storm season gusts, particularly in exposed areas near I-90.
