General Atomics Aeronautical Systems is seeking approval for a Conditional Use Permit (CUP) and Major Variance for the expansion of the 800-acre El Mirage Airfield facility. The proposal is for an aircraft assembly hangar and avionics assembly & testing with associated accessory office and support facilities (Project). The Proposed Project is located on approximately 20 acres of parcel APN: 0457-041-02, which is an approximately 77-acre parcel. It also includes approximately one acre of the adjacent parcel to the west, APN: 0457-041-03, which totals approximately 159 acres. Additionally, the approximately 77-acre parcel APN: 0457-041-04 is incorporated into the project site. The three parcels totaling approximately 312 acres (APNs:
0457-041-02, -03, and -04) are planned to be merged as part of the project. The project site located in El Mirage, unincorporated San Bernardino County, California approximately ten miles west of the City of Adelanto (see Figure 1-Regional Location). More specifically the airfield is at 73 El Mirage Airport Road within the 1st Supervisorial District (see Figure 2-Project Vicinity). The airfield is designated Rural Living (RL) and General Industrial (GI) according to the San Bernardino County Countywide Plan/Policy Plan 2020 (Policy Plan), with zoning designations of Rural Living (RL) and Institutional (IN). The airfield opened in 1942 as a satellite field for the
Victorville Army Airfield (Victorville AAF) and was used as a training facility during World War II. After the war, the field was used as a civil airfield. Since 1985 the El Mirage Field has been used by General Atomics as their unmanned air vehicle flight test center. Conditional Use Permit and Major Variance for the development of: (1) a 118,020-square-foot hangar building, (2) a 19,512-square-foot ground control building, and (3) a 20,000-square-foot stockroom building for the manufacturing and testing of unmanned aerial vehicles (UAVs) located at 73 El Mirage Airport Road, El Mirage, CA (APNs: 0457-041-02, -03, and -04).
