About this map

Pearl Harbor's complex shoreline, featuring Middle Loch and East Loch, serves as the southern anchor for this detailed topography of southern O‘ahu. The landscape transitions from the urban density of Pearl City, Waipahu, and Aiea to the deep, parallel incisions of Panakauahi Gulch and Punanani Gulch. These natural drainages dictated the development patterns of upland residential communities like Pacific Palisades and Mililani Town, which sit atop the plateaus between gulches.

Industrial and agricultural history is visible through the extensive network of irrigation infrastructure, including the Koolau Ditch Tunnel, Waiahole Ditch, and Old Ahern Ditch. Local history researchers will find the Honolulu Plantation Cem and Aiea Cem preserved among the modern transit corridors of the H-1 and H-2. From the Wahiawā Reservoir in the north down to the coastal fishpond of Loko Paaiau, the map documents a territory defined by its water management and rapid suburban expansion.
