The National Science Foundation (NSF) will remain in Carlyle, after it announced an official search for office space last summer. ... Through NSF’s decision, Alexandria will retain 1,600 NSF federal employees and scientist jobs, the city announced in a release Friday evening. Local officials intend to work with the U.S. General Services Administration (GSA) and property owner LCOR Inc. “over the coming months” to ensure a smooth transition.

NSF, which moved to Alexandria in 2017, was displaced from its 2415 Eisenhower Avenue headquarters after the Trump administration announced in June that it would be overtaken by the U.S. Department of Housing and Urban Development. The agency’s new location in the Edmund Randolph building at 401 Dulany Street is adjacent to the U.S. Patent and Trademark Office.
