Commission backs more granular floodplain language allowing engineering review for sewer exceptions

The Planning Commission considered a proposed amendment to HCC 10‑4A‑31 that would clarify which utilities must be above a stated elevation and allow sanitary sewer systems to be evaluated and approved on a case‑by‑case basis by engineering. Staff explained the amendment seeks to be more granular than the previous blanket standard (4220 feet) by listing specific infrastructure to be kept above the elevation while enabling engineering review for sewer systems (vacuum or other specialized systems) that could function at slightly lower elevations.
