"Glamour" of OC / Tustin Legacy - AQMD Sign - "Don't Excuse Our Dust"
The AQMD (Air Quality Management District) imposes strict (some would say excessive) standards for "particulate matter" - dust. Here a portion of the former Tustin US Marine Corps Air Station, next to one of the huge blimp hangers, is being graded for redevelopment. New streets continue to be cut through the former base, making access to viewing the hangers a bit easier.
