The University of Hawaii manages lands on Maunakea including the Halepōhaku mid-level astronomy support facilities at 9,200' elevation (19 acres), a 400-yard corridor along the Summit Access Road (723 acres), and the Maunakea Science Reserve (11,288 acres). The University designated 10,760-acres of the Maunakea Science Reserve as a Natural/Cultural Preservation Area, with no development activity. The remaining 525 acres (5%) of the Science Reserve are designated as an Astronomy Precinct.
The Mauna Kea Science Reserve Master Plan—a policy guide for University management of Maunakea, including protection of the cultural, natural, and scientific resources—was adopted by the Board of Regents in June 2000.
In 2009 the University developed the Mauna Kea Comprehensive Management Plan, followed in 2010 by the Natural Resources Management Plan, Cultural Resources Management Plan, Public Access Plan, and Decommissioning Plan. These management plans, approved by the State of Hawaiʻi Board of Land and Natural Resources, are the State's plans for managing Maunakea.
The Office of Mauna Kea Management, together with the Mauna Kea Management Board and Kahu Kū Mauna share responsibility for implementing these plans. Since June 2000, management of Maunakea requires input and participation from the community regarding daily activities, development of policies and programs, and review of proposed projects.
