The Annex includes a military reservation, also named Nimitz Hill, with housing for senior U.S. military officers on Guam.[2] The headquarters building for Joint Region Marianas / Naval Forces Marianas and the NAVFAC Marianas building are nearby, close to the actual peak of Nimitz Hill.
The Fonte Plateau Unit of War in the Pacific National Historical Park is located in the southeast of the community.[3] The Asan Bay Overlook of the Park's Asan Inland Unit, with its memorials, is accessed through Nimitz Hill Annex. The Libugon Viewpoint, near the eastern boundary of the CDP, offers views over Maina and Agana Heights to Agana Bay. The NRHP-listed Fonte River Dam, often used as a water recreation area, is located in the southeast of Nimitz Hill Annex.
The Joint Typhoon Warning Center was established at Nimitz Hill in 1959, but Typhoon Karen destroyed the center in 1962. After being rebuilt in 1965, it remained until January 1, 1999, when the center was moved to Pearl Harbor following the Base Realignment and Closure legislation of 1995.[4] Nimitz Hill is also home to former United States Naval family housing.
On August 6, 1997 Korean Air Flight 801 crashed immediately south of the Nimitz Hill Annex area.[5]
