2024 Map of Waipahu

Tracing the inland terrain reveals an intricate network of irrigation and water management features, such as the Waiahole Ditch and Waikakalaua Ditch, which cut across the gulches of the Ko'olau Range. Local history is preserved in several significant sites, including Saint Josephs Church Cem and Sunset Memorial Park, while the Pearl Harbor National Wildlife Refuge provides a protected contrast to the industrial and naval activity of the Middle Loch and East Loch.
