Hālawa is a stream, a valley, an ahupua‘a, a neighborhood, and a census-designated place (CDP) located in the ‘Ewa District, City & County of Honolulu, Hawai‘i. Hālawa Stream branches into two valleys: North and South Hālawa; North Hālawa is the larger stream and fluvial feature. Their confluence is within the H-3/H-201 highways exchange. Most of Hālawa Valley is undeveloped.
The upland, or Mauka, portion of Hālawa is sacred to Papahanaumoku, the Kanaka Maoli form of Mother Earth, as it is, according to legend, her birthplace and primary home, as well as one of only two or three known remaining Hale o Papa, womenʻs temples where Papa is worshipped. The valley contains many religious and other cultural sites sacred to Kanaka Maoli. Although many sites were destroyed by the invasion of Kahekili II and especially by the building of the highly controversial H-3 Freeway, many remain and are cared for by Kanaka Maoli Aloha ʻAina practitioners to this day.
In the last two decades, North Halawa has been the site of a very public battle over the religious sites and ecological resources destroyed by H-3, which is the most expensive freeway per mile in human history. At least two species were driven to probable extinction (none have been sighted since construction began), many more are declining rapidly, the main aquifer of the area was badly damaged, and religious sites were seriously impacted. Although the freeway was opened in 1997, many are still fighting for mitigation of these impacts, and some are asking for the freewayʻs closure. In 1993, thirteen cultural practitioners were arrested while conducting a ceremony to pray for the healing of the valley. Their lele (religious altar) was destroyed, and the caretakers of the area were barred from entrance to the sites. Today, some of these caretakers, many of them kupuna (elders), have returned to care for the sites, although they now do so through a layer of soot and with the roar of the freeway as a constant sonic backdrop. Many kanaka maoli do not use the freeway because of these impacts, and because of the lasting belief that the road is haunted -- an often-attributed explanation for the high accident rate on the freeway (more generally believed to be caused by the high speeds often used by the motorists who traverse it).
Where the valley widens out closer to Pearl Harbor occur residential neighborhoods: Foster Village adjacent to Āliamanu; and the stadium area between Aloha Stadium and Makalapa. The interfluve (uplands between valleys) on the west comprises Halawa Heights, extending up to Camp H. M. Smith. Along the lower, western edge, Halawa Heights merges with the neighhborhoods of ‘Aiea. As of the 2000 Census, the CDP had a total population of 13,891.
The U.S. Postal Code for Hālawa Heights is 96701 (the same as for ‘Aiea). The postal code for Foster Village, the stadium area, and Makalapa is 96818 (the same as Āliamanu).
Hālawa is located at 21°22'39" North, 157°55'22" West (21.377633, -157.922759). According to the United States Census Bureau, the neighborhood has a total area of 6.0 km² (2.3 mi²). 6.0 km² (2.3 mi²) of it is land and none of it is covered by water.
The route of Interstate H-3 extends from its western terminus with east-west Moanalua Freeway (H-201; connecting eastward to Honolulu or westward to H-1 and ‘Aiea) to the 1100-foot (335-m) elevation entrance into the Tetsuo Harano Tunnels penetrating the Ko‘olau crest. The freeway continues beyond to Kāne‘ohe on windward O‘ahu. A significant proportion of Interstate H-3 within the valley is carried on a viaduct (see photo at right). Although very expensive to construct, the viaduct is the only way to construct a freeway of this magnitude through such a narrow valley without flooding and destabilization concerns; it is also believed to offer some returns in terms of preservation of both archeological sites and stream ecology.
