HCC §23-45

Street intersection angles and corner curve rules

Read the official text at hawaiicounty.gov ↗

This section sets rules for how streets must meet at intersections. Streets should cross at right angles, but can use a smaller angle if the land requires it, as long as it is not less than 60 degrees unless specially designed. Corners at non-right-angle intersections need a minimum curve radius, and the public works director can require a bigger curve if needed for safety.

The ordinance, as written (Hawaiʻi County) — Intersection angles; corner radius

A copy, taken August 21, 2026. The version published by Hawaiʻi County is the one that governs, and it may have changed since. Check it before relying on anything here.

(a) Streets shall be laid out to intersect at right angles except where topography requires a lesser angle, but the angle shall not be less than sixty degrees unless there is a special intersection design. (b) Intersections which are not at right angles shall have a minimum corner radius of twenty-five feet along the right-of-way lines of the acute angle. All other right-of- way lines at these intersections shall have a corner radius of not less than twenty feet. If unusual topographical conditions exist that will impair sight distances and create a traffic hazard, the director of public works may specify a larger corner radius.
