This site became an activated FAA radar site on 30 Jun 1997, furnishing radar track data to the FAA ARTCC's and to USAF Direction Centers. The initial FAA search radar was and still is an ARSR-4.

This site replaced much the coverage of both the Crescent City FAA Radar Site (J-83) located on the site of the former Klamath Air Force Station and the former Point Arena Air Force Station, a joint-use facility operated by civil service personnel. These two sites deactivated their radar mission coincident with the activation of the Rainbow Ridge FAA Radar Site.

The radar site data is available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA Oakland ARTCC and adjacent ARTCCs.
