EXPLANATION AND SUMMARY:
Navy Federal Credit Union (NFCU)'s headquarters, addressed at 820 Follin Lane, SE, was constructed in three phases from the late 1970s through the 1990s and is currently undergoing modernization. The existing emergency generators are aging and require replacement to maintain reliable service.

o Supporting a safe community for adjacent neighborhoods through noise miti...
