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.

The KILO workspace: a parcel map of Oʻahu with the cultural, water, flood and land-use data layers switched on, and the cited parcel read open beside it. — The workspace a read opens into — every layer drawn from a cited source, and the reasoning shown line by line.

And the read is where the work starts, not where it ends: the pathway it produces becomes a project you can track — filings, review clocks, submittal checklists, agency comments — with exports for the deal file. See everything a read carries →
