American Samoa's lone hospital, Lyndon B. Johnson Tropical Medical Center, is located in Fagaʻalu.

Later that month, the battalion cleared large jungle areas and began on the construction of the Camp Samuel Nicholas in Fagaʻalu.

This expansive complex featured over 50 buildings, such as a U.S. Marine camp, multiple warehouses and truck sheds, a large mess hall, shower facilities, a tailor shop, and a post exchange.

The telephone exchange was situated underground in the far northwestern corner of the installation and was accessed via a short tramway.

Gobie fish, Mountain bass, and Freshwater eel have been observed in Fagaʻalu Stream.

[8] In the central parts of Fagaʻalu is a road turning north to LBJ Hospital and other medical facilities.

During bad weather, waves break over Whale Rock, making it more noticeable due to the surf.

As of 2000, the Samoa Maritime Quarry generated around 500 cubic yards (380 m3) of reject material per week.

[12] Lyndon B. Johnson Tropical Medical Center is the only hospital in American Samoa and the only prescription pharmacy on the island.

A 0.6-mile (0.97 km) hike past the LBJ Tropical Medical Center leads to a small rock quarry.

Historically, residential development has taken place along the south and north sides of Fagaʻalu Stream.

Another residential area is found upland of Fagaʻalu Park along the shoreline road and adjoining steeper slopes.
