EDWARDS AIR FORCE BASE, Calif -- The Air Force Flight Test Center and LUZ International Unlimited signed a navigation easement that held the Air Force exempt from any damages to LUZ facilities resulting from normal sonic boom overpressures. LUZ had planned to construct several solar plants near Harpers Dry Lake, within the Center’s R-2515 range and adjacent to the Black Mountain low-altitude supersonic corridor. The easement promised to be a new approach to dealing with the problem of encroachment upon the Flight Test Center’s facilities.
During the last 16 years, nine solar power plants have been built, near Los Angeles, by Luz International Limited.
Harper Lake is a dry lake located in the Mojave Desert near the small community of Lockhart, California, in northwestern San Bernardino County of Southern California. The lake is accessible from Harper Lake Road, which runs north off of State Route 58 midway between Boron and Barstow.
