Research notes

Ellsworth AFB sits ~10 miles northeast of Rapid City and was selected in 2019 as the first operational base for the B-21 Raider. AICUZ is advisory-on-locals but DoD encourages adoption into Meade County, Pennington County, Rapid City, Box Elder, Summerset, and Piedmont zoning codes — adoption status varies by jurisdiction. Box Elder (immediately adjacent) has the strongest AICUZ overlay. The B-21 basing increases the AICUZ relevance window; expect a refreshed AICUZ study and potentially expanded noise contours in the coming years. FAR Part 77 imaginary surfaces are independently enforceable by FAA regardless of local AICUZ adoption.
