HCC §10-19
How far cut or fill slopes must be from property lines
Read the official text at hawaiicounty.gov ↗This section sets minimum distances between a cut or fill slope and the neighboring property line, based on the slope's height. The distances can be reduced if a retaining wall is approved or a soil report shows it is safe. Tall retaining walls may need a professional engineer's design.
