What a KILO read answers here
The directory entry above is the public record's surface. A KILO read is the layer underneath — the parcel-level answers a project actually turns on:
- Zoning & entitlement — county zoning, state land-use district, and whether the intended use is by-right or discretionary.
- Flood — FEMA flood zone and base-flood elevation posture — including the June 2026 Oʻahu FIRM update.
- Wastewater — cesspool / septic / sewer status and the HAR §11-62 and Act 125 rules that apply.
- Shoreline & sea level — shoreline setback and the State SLR-XA exposure ladder.
- Contamination — DOH HEER and EPA facility context near the parcel.
- Cultural resources — the parcel's HRS §6E review pathway and documented cultural-resource context, with the reasoning shown.
