Rules for naming streets in Honolulu

Street names within the city shall comply with the following requirements: (1) Street names selected shall consist of Hawaiian names, words, or phrases and shall be selected with a view to the appropriateness of the name to historic, cultural, scenic, and topographical features of the area; (2) Street names selected shall not duplicate existing street names in spelling or sound, and shall be as dissimilar as possible in spelling or sound from any existing street names; (3) Street names shall be selected so as not to exceed the space limitation of a standard street name sign of the department of transportation services (normally 18 spaces); (4) Streets that constitute a continuation of an existing street shall be given the same name as the existing street; (5) Streets that are continuous shall bear the same name throughout; (6) A street shall be entitled to a street name only if: (A) The roadway has a legally defined right-of-way, by roadway lot or easement; however, street names shall be considered for subdivisions as to which tentative approval has been granted and construction plans have been approved by the city; (B) The roadway has a minimum right-of-way of 18 feet and is paved; and (C) The roadway serves two or more lots or units; and (7) Any street names adopted after the effective date of this article shall include appropriate diacritical marks, which shall appear on the street name sign prepared by the department of transportation services. Appropriate diacritical marks shall also be required for all replacement signs for street names in effect on the effective date of this article, and to all signs where a newly named street constitutes an extension of a street for which a name is in effect on the effective date of this article. The department of planning and permitting and the department of transportation services may take all steps necessary to redesignate the names of existing streets to include appropriate diacritical marks where such redesignation is found to be necessary or appropriate. )
