Boundaries for State Land Use Districts of Oahu, including state land use designation. All land in Hawaii is classified as one of four types: Conservation, Agricultural, Urban, and Rural. However, there is no rural land use classification on Oahu. This data originated with the State but has been edited by the City and County of Honolulu to reflect land use changes pertinent to the Department of Planning and Permitting.

Areas designated as Special Districts by the City and County of Honolulu. The purpose of a special district is to provide a means by which certain areas in the community in need of restoration, preservation, redevelopment or rejuvenation may be designated as special districts to guide development to protect and/or enhance the physical and visual aspects of an area for the benefit of the community as a whole.

This database consists of a series of maps showing tsunami inundation based on historical events (1946 Aleutian, 1952 Kamchatka, 1957 Aleutian, 1960 Chile, and 1964 Alaska tsunamis) and hypothetical events (two great Aleutian earthquakes with moment magnitude (Mw) 9.3 and 9.6 as potential sources). Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report.

Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Shoreline datasets are provided by NGS (2017).
