The ordinance, as written (Hawaiʻi County) — Fill materials
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.
The fill material may consist of rock, gravel, sand, soil, or a mixture thereof. Except for slopes, the fill shall be compacted to ninety percent of maximum density as determined by the ASTM soil compaction test D1557, as amended. The director of public works shall inspect the work and may require adequate inspection and compaction control substantiated by test results by an engineer qualified to prepare an engineer’s soils report. These requirements may be modified by the director of public works if the permittee submits an engineer’s soils report substantiating with appropriate investigation and analysis that the required ninety percent compaction density may be lowered without causing excessive settlement, creep, or stability problems.
