Reconnaissance Level Architectural Historic Resource Survey, Honoapi'ilani Highway

The WSP reconnaissance survey is cited extensively in the thesis for documenting plantation-era ditch infrastructure, reservoir conditions, and historic water conveyance systems. The survey identifies multiple resources — including AR 9, AR 22, AR 31, AR 34, and AR 39 — where modern roads cut through ditch segments requiring realignment or bridging to restore flow continuity. The thesis uses this survey data for ditch rehabilitation planning and reservoir restoration, noting that cut-basalt and concrete-lined reservoirs AR 9 and AR 31 have a combined historical capacity of 5 million gallons daily and retain structural integrity despite decades of disuse.
