2017 Map of Koko Head

About this map

Waimanalo and the eastern ridges of O'ahu are defined by a complex network of valleys and coastal development along the windward and leeward shores. To the north, the Maunawili Valley is carved out between Olomana Ridge and the heights of the Ko'olau Range, featuring critical water infrastructure like the Kailua Ditch and Maunawili Ditch. The geography shifts dramatically across the range into the deeply incised Pia Valley, Kūpaua Valley, and Kuli'ou'ou Valley, which funnel toward the suburban expanses of East Honolulu. Along the southern coast, the development of Hawai'i Kai surrounds the modified Kuapā Pond, while the preserved marine environment of Hanauma Bay remains a prominent landmark. This 2017 survey details the dense modern street grids of Portlock and 'Āina Haina contrasted against the precipitous terrain of Kamehame Ridge and the volcanic caldera at Ka'au Crater.
