The land division is described as “Seven large streams begin as springs and tributaries on slopes in the Koʻolau Range, on Aniani Nui Ridge, and on Olomana, and then cross Maunawili Valley, carrying water to every tributary valley and lowland plain in the catchment. Clockwise from the south, these streams include ʻAinoni, Maunawili, ʻŌmaʻo, Palapū, Kahanaiki, Olomana, and Makawao. At least fifty springs – forty-three seasonal and seven perennial – recharge the streams, which eventually join Maunawili Stream today, to flow northeast through Kawainui Marsh and empty into Kailua Bay.” (Brennan & Allen, 2009, p. 73) 

• Maunawili Valley in the ahupuaʻa (land division) of Kailua is home to irreplaceable resources which are critical to the health and welfare of the people of Hawaiʻi today and to future generations.  These biocultural resources include ancient and historic sites, critical water resources, important agricultural lands, native and endangered species, and historic trails and roads.

• From its earliest settlement until the early 1980s (before the development of the golf course), land use in Maunawili was primarily agricultural. Today the lands HRT/Weinberg proposes to subdivide include 50% of the land in Kailua zoned Agriculture and almost all of Kailua’s Hanalei series soil, the richest and most fertile soil in the islands.

• Extensively farmed in kalo and other crops and the kalo from the area was famed for its sweetness and specifically requested by the Aliʻi. 

• Based on land use in Maunawili Stream, nutrient levels are likely derived from past agricultural practices of using fertilizers or possible landscaping practices at the Luana Hills Golf Course

• The Maunawili Falls Trail was a heavily trafficked hiked that led hikers to a unique 20ft waterfall that was not managed or cared for in decades. Today the overuse, trampling of ecosystems, severe soil erosion, numerous injuries, emergency evacuations of hikers, and negative impacts on the residents has left the hike closed
