Counties May Streamline SMA Permitting, Not Eliminate the Non‑Delegable CZMA “Assessment” (Final EA Required; No Categorical Self‑Certification Exemptions)

I. Introduction

In Maui Tomorrow Foundation v. Maui Planning Commission (Haw. July 22, 2026), the Supreme Court of Hawaiʻi reviewed amendments to Maui County’s Special Management Area (SMA) rules adopted by the Maui Planning Commission (MPC). The plaintiff, Maui Tomorrow Foundation, challenged the amended rules as inconsistent with Hawaiʻi’s Coastal Zone Management Act (CZMA), Hawaiʻi Revised Statutes (HRS) chapter 205A, and with the State Constitution’s public trust obligations.

The key dispute was structural: whether Maui County could, by rule, remove categories of activities from the CZMA’s required “assessment” that determines if an activity is “development” requiring an SMA permit—and, relatedly, whether MPC could shift that determination to applicants (including by self-certifying exemptions and by relying on draft environmental assessments).

The circuit court invalidated (1) categorical exemptions (Maui County Code (MCC) § 12-202-11.1), (2) a “same scope” continuation/repair/renovation exemption (MCC § 12-202-11.2), and (3) the substitution of a draft environmental assessment (EA) for a final EA (MCC § 12-202-12(c)(11)). The Hawaiʻi Supreme Court affirmed, emphasizing that administrative efficiency cannot override statutory mandates or the constitutional public trust.

II. Summary of the Opinion

The court held that MPC’s amended rules were unlawful because they:

• Contradicted the CZMA by creating categorical exemptions that bypass the statutory three-step “assessment” (from Leslie v. Bd. of Appeals of Cnty. of Hawaiʻi) used to determine whether an SMA activity is “development” requiring a permit.
• Unlawfully delegated to private, regulated parties a duty the CZMA assigns to the “authority” (the county planning commission), a defect compounded by Hawaiʻi’s constitutional public trust doctrine (Haw. Const. art. XI, § 1).
• Violated the CZMA’s continuing-duty concept (the “whenever the authority finds” cumulative impact mandate in HRS § 205A-22) by allowing indefinite reliance on past exemptions/permits under an undefined “same scope” standard without renewed review.
• Eroded environmental review by requiring only a draft EA rather than a final EA, undermining process, agency oversight, and public participation central to environmental law and the CZMA’s objectives.

In affirming the circuit court, the Supreme Court drew a bright line: counties may streamline permitting procedures under HRS § 205A-29, but they may not erase or outsource the mandatory assessment that triggers whether permitting is required at all.

III. Analysis

A. Precedents Cited

1. Leslie v. Bd. of Appeals of Cnty. of Hawaiʻi (109 Hawaiʻi 384, 126 P.3d 1071 (2006))

Leslie supplies the analytical framework that anchors the decision. The court treated the three-step inquiry as the CZMA’s operative mechanism for deciding whether an SMA activity is “development”:

1. Is the activity within the statutory definition of “development” in HRS § 205A-22?
2. If so, does it fall within a statutory exclusion?
3. If excluded, does it still have “cumulative impact” or “significant environmental or ecological effect” such that it is “development” anyway?

The Maui amendments were invalid largely because they attempted to skip this process categorically and permanently. The court reinforced that Leslie is not a mere “best practice”; it operationalizes the statute’s command.

2. Administrative rule limits: Asato v. Procurement Policy Bd. and Agsalud v. Blalack

The court relied on Asato v. Procurement Policy Bd., 132 Hawaiʻi 333, 322 P.3d 228 (2014), and its quotation of Agsalud v. Blalack, 67 Haw. 588, 699 P.2d 17 (1985), for core administrative-law principles: rules exceeding statutory authority are invalid (also reflected in HRS § 91-7(b)), implied powers must be “reasonably necessary,” and rules may not contradict the statute they implement.

These cases frame the court’s statutory analysis: Maui County’s rules were not an allowed “implementation detail” but a contradiction—redefining “development” and disabling required review.

3. SMA decisionmaking cannot be shifted to applicants: Alaloa, Kaleikini, and Ka Paʻakai

The opinion treats unlawful delegation as both statutory and constitutional error.

• Alaloa v. Planning Comm'n of Maui Cnty., 68 Haw. 135, 705 P.2d 1042 (1985), is the direct SMA precedent: MPC could not condition approval in a way that left compliance determinations to the developer. The Alaloa concerns—financial self-interest, lack of neutral expertise, and lack of public accountability—map onto Maui’s amended exemption structure, which relied on private parties’ unreviewed assertions.
• Kaleikini v. Yoshioka, 128 Hawaiʻi 53, 283 P.3d 60 (2012), reinforces that Alaloa turned on “unlawful delegation of duty” to developers, validating the court’s characterization of Maui’s rulemaking as impermissible outsourcing.
• Ka Paʻakai O Ka ʻAina v. Land Use Comm'n, State of Hawaiʻi, 94 Hawaiʻi 31, 7 P.3d 1068 (2000), supplies the constitutional register: public trust and cultural-resource protections require the agency to make findings and demonstrate it exercised discretion; it may not leave protection to private parties because harms become irreversible once projects begin.

4. Environmental impact is central to SMA: Sandy Beach Def. Fund and consistency findings

Sandy Beach Def. Fund v. City Council of City & Cnty. of Honolulu, 70 Haw. 361, 773 P.2d 250 (1989), is cited for the proposition that the CZMA’s impact analysis drives SMA assessment and for the statutory findings required by HRS § 205A-26(2). The opinion uses Sandy Beach to reject Maui’s reframing of exemptions as outside “development”: the statute’s breadth is intentional, and the environmental-effect inquiry is the statute’s safeguard.

The opinion also cites Alaloa for the requirement that any permitted development must be consistent with CZMA objectives and policies. This supports the court’s insistence that Maui could streamline procedure but not dismantle substantive screening.

5. Public trust doctrine: Kelly and trustee accountability: Carmichael

The court grounds non-delegability in the Constitution. Kelly v. 1250 Oceanside Partners, 111 Hawaiʻi 205, 140 P.3d 985 (2006), is cited to emphasize the public trust doctrine as a “fundamental principle of constitutional law in Hawaiʻi,” requiring the State to take initiative “at every stage.” Carmichael v. Bd. of Land & Nat. Res., 150 Hawaiʻi 547, 506 P.3d 211 (2022), supplies the accountability requirement: the trustee agency must demonstrate that it exercised the discretion vested by constitution and statute.

Together, these cases elevate the dispute beyond statutory interpretation: even if a statute were ambiguous, the public trust doctrine would demand meaningful agency engagement rather than self-regulation by those seeking to use coastal resources.

6. Environmental process values: Kepoʻo v. Watson

For the EA issue, the court relied on Kepoʻo v. Watson, 87 Hawaiʻi 91, 952 P.2d 379 (1998), emphasizing that “procedural and informational requirements” are “at the heart” of Hawaiʻi’s Environmental Policy Act (HEPA), HRS chapter 343. That framing supported the conclusion that substituting draft EAs for final EAs undermines the integrity of environmental review and public participation.

B. Legal Reasoning

1. The opinion’s central distinction: “assessment” vs. “permitting”

The court accepted Maui Tomorrow’s core conceptual split:

• Assessment is the CZMA-mandated gatekeeping determination—under HRS § 205A-22 and Leslie—deciding whether an activity is “development” requiring an SMA permit. The assessment includes environmental impact review (especially at step 3).
• Permitting is the county’s process for how a “development” permit application is handled (procedures, notice, hearings), which counties can “streamline” under HRS § 205A-29 so long as they remain consistent with chapter 205A.

Maui’s amended rules were invalid because they were not mere procedural streamlining. They altered the substantive trigger—whether an activity is treated as “development”—by removing categories from the assessment and by removing the agency from the decision.

2. Why categorical exemptions conflict with HRS § 205A-22

MCC § 12-202-11.1 listed fifteen exempt activities and declared them to have no significant environmental or ecological effect, making them exempt from SMA permitting without the Leslie assessment. The court found this contradicted the statutory architecture: the CZMA itself contains exclusions, but it keeps them conditional through step 3’s “cumulative impact or significant environmental or ecological effect” override.

In the court’s view, Maui County attempted to do what the legislature reserved to itself—rebalancing environmental protection and administrative burden. The opinion reinforced this conclusion with legislative history, including: (1) S. Stand. Comm. Rep. No. 174-84 (1984) (exemptions meant to ease processing “without compromising” program intent), and (2) S. Stand. Comm. Rep. No. 936 (1979) (if exemptions are inadequate, “the Legislature can make the necessary adjustments”).

3. The non-delegation holding: the “authority” must do the work

A major doctrinal move in the opinion is treating the amended rules as an unlawful delegation, even where they retained the right verbal standard. The CZMA assigns the determination to the “authority” (the planning commission). While HRS § 205A-1 allows the commission to “delegate” administration “as appropriate,” the court read that power as limited to delegation to government actors—not to regulated parties—consistent with Alaloa.

The decision’s sharpest statement is that Maui’s approach “delegated its duty to assess potential environmental harm to the regulated parties themselves.” This was impermissible under the statute and incompatible with public trust obligations, because public trust decisionmaking requires public accountability and demonstrable exercise of discretion.

4. Exemption (j): even “good standards” fail if the wrong decisionmaker applies them

The court isolated exemption (j), which covered “[t]raditional native Hawaiian cultural practices ... that do not have a detrimental environmental or ecological effect.” Unlike the other exemptions, it included an environmental safeguard on its face. Yet it fell for the same structural reason: the rules left the determination to private actors without commission verification—“a standard nobody checks is an honor system.”

Notably, the opinion does not treat cultural practice as disfavored; rather, it insists that determinations about environmental effects in the SMA must be made through lawful, accountable processes that protect both resources and rights, consistent with Ka Paʻakai’s insistence on agency findings.

5. MCC § 12-202-11.2 and the “whenever” (continuing duty) problem

MCC § 12-202-11.2 allowed continued, repaired, or renovated activity within the “same scope” of prior exemptions or permits, with no defined “scope” and no requirement for renewed agency findings. The court held this contradicted HRS § 205A-22’s command that “whenever the authority finds” cumulative impacts, excluded activities must be treated as development.

This part of the opinion foregrounds cumulative impacts and changing conditions: what was harmless years ago may become harmful as circumstances change or as incremental effects compound. The rule’s freeze-in-time approach prevented the “authority” from making the statutorily required renewed evaluation.

The court acknowledged that Act 70 amended the “whenever” language for Maui County (changing it to “if the authority finds”), but held the substantive duty persists—particularly in light of Maui County’s public trust responsibilities.

6. Final EA requirement: why drafts are not enough

By requiring only a “draft” EA, Maui’s amended MCC § 12-202-12(c)(11) invited decisionmaking on incomplete and revisable information. The court reasoned this undermined environmental review and public participation—values embedded in HEPA (HRS chapter 343), in the CZMA’s objectives (HRS § 205A-2(c)(7)(C)), and in Kepoʻo.

The opinion also referenced HEPA’s administrative rules, including HAR § 11-200.1-16 and HAR § 11-200.1-17, to show that any “routine activities” exemption is narrow, case-by-case, and sensitive-environment aware—whereas Maui adopted a blanket weakening in the SMA, precisely where rigor is most warranted.

C. Impact

1. A clear constraint on county SMA rulemaking

The decision functions as a statewide warning: counties cannot use “efficiency” to redefine “development,” bypass the Leslie assessment, or create categorical exemptions that eliminate the statutory step-3 environmental safeguard. HRS § 205A-29’s permission to streamline procedures is not permission to alter the statutory trigger for regulation.

2. Strengthening “non-delegable” public trust administration in land-use practice

The court’s repeated emphasis that SMA protection is “non-delegable” integrates administrative law with constitutional public trust doctrine. Future challenges to coastal permitting and exemptions will likely cite this case for the proposition that agencies must themselves make—and be able to demonstrate—environmental determinations, rather than relying on self-certification or post hoc enforcement.

3. Practical consequences for applicants and agencies

• Applicants should expect renewed emphasis on the front-end “assessment” (including cumulative impact review), rather than relying on categorical exclusions.
• Counties seeking workload reduction may need legislative change, additional staffing, improved internal triage that still fits within Leslie, or technology/process reforms that streamline without shifting substantive judgment to applicants.
• Draft-only environmental documents are unlikely to survive challenge where they are used to satisfy a final-review function, especially in sensitive areas like the SMA.

IV. Complex Concepts Simplified

Special Management Area (SMA)

A coastal zone created by the CZMA where “development” is tightly regulated to protect sensitive shoreline and coastal resources. No “development” may proceed without an SMA permit.

“Development” (HRS § 205A-22)

A broad statutory term covering activities like placing material, grading/extraction, changing land-use intensity, changing water-use intensity, and constructing/altering structures. The breadth is intentional so the agency can screen for environmental harm.

Assessment vs. Permitting

Assessment is the threshold decision—does the activity count as “development” (and thus require an SMA permit)? Permitting is the procedural process for approving a development once it is determined to require a permit.

Categorical exemption

A blanket rule saying a whole class of activities is exempt. The court held counties cannot create categorical exemptions that bypass the CZMA’s required assessment and step-3 impact override.

Cumulative impact

Harm that results from repeated or incremental activities over time. Even if a single activity seems minor, many similar actions can collectively create significant environmental effects.

Public trust doctrine (Haw. Const. art. XI, § 1)

A constitutional principle that the State and its political subdivisions hold public natural resources “in trust” for the people and must actively protect them. A trustee must exercise its own judgment and cannot hand core protective decisions to self-interested private parties.

Environmental Assessment (EA); Draft vs. Final

An EA is an environmental review document. A draft EA is preliminary; a final EA reflects completion of review steps and is designed to support accountable decisionmaking and public participation. The court held a draft EA cannot substitute for the final EA in the SMA assessment context.

V. Conclusion

Maui Tomorrow Foundation v. Maui Planning Commission establishes and clarifies a controlling rule for Hawaiʻi coastal governance: counties may streamline SMA permitting, but they may not eliminate, categorically bypass, or privatize the CZMA’s mandatory SMA assessment. The three-step framework from Leslie v. Bd. of Appeals of Cnty. of Hawaiʻi remains the statutory pathway for determining “development,” and the “authority” must perform that work consistent with statutory directives and Hawaiʻi’s constitutional public trust obligations.

The opinion’s broader significance lies in its insistence that coastal protection is not an optional administrative feature. It is a statutory and constitutional duty—one that requires transparent process, meaningful agency findings, and public accountability, particularly in Hawaiʻi’s most sensitive shoreline environments.
