Background
The Maui Planning Commission amended its Special Management Area rules in August 2024. The rules created fifteen categorical exclusions from the Coastal Zone Management Act’s definition of “development,” allowed previously approved or exempt activities to continue, be repaired, or be renovated within the undefined “same scope,” and required only a draft environmental assessment with an application.
Maui Tomorrow Foundation challenged the rules, arguing that they eliminated the Commission’s role in determining whether activities required SMA permits and transferred environmental-impact judgments to regulated landowners. The circuit court granted summary judgment, struck the categorical-exemption and continuing-use provisions, and restored the final environmental-assessment requirement. Maui County and the Commission appealed, and the Hawaiʻi Supreme Court accepted transfer.
The Court’s Holding
The supreme court affirmed. It held that MCC § 12-202-11.1 exceeded the Commission’s statutory authority because the Commission could streamline permitting but could not categorically remove activities from the CZMA assessment that determines whether they constitute “development.” Fourteen exemptions conflicted with the statute’s broad definition and environmental-impact safeguard; the Native Hawaiian cultural-practices exemption used an appropriate environmental standard but was still invalid because private parties, rather than the Commission, applied it.
The court independently held that assigning the assessment to regulated parties violated both the CZMA and Maui County’s nondelegable public-trust duty under article XI, section 1 of the Hawaiʻi Constitution. It also invalidated MCC § 12-202-11.2 because a prior approval could not permanently foreclose renewed consideration of cumulative effects, and it upheld removal of the word “draft” from MCC § 12-202-12(c)(11) because an unfinished EA lacked the public review, agency oversight, and reliable information required for meaningful environmental assessment.
Key Takeaways
- Counties may streamline SMA permitting procedures, but they may not bypass the statutory assessment used to decide whether an activity is a “development.”
- A county planning commission cannot delegate environmental-impact determinations to applicants or landowners with a financial interest in the outcome.
- Prior approval does not eliminate the duty to consider later cumulative impacts, and a draft EA cannot categorically replace a final EA in SMA review.
Why It Matters
The decision reinforces that Hawaiʻi’s coastal-review process is not merely procedural. County authorities must themselves evaluate potential environmental harm before allowing covered SMA activities to escape permitting, and administrative workload does not justify transferring that responsibility to regulated parties.
The ruling also grounds those statutory duties in Hawaiʻi’s constitutional public-trust doctrine, making clear that state and county trustees must actively protect coastal resources for present and future generations.
