Hawaii DLNR: Land, Water, and Natural Resource Management

The Hawaii Department of Land and Natural Resources sits at the intersection of everything the islands are made of — volcanic rock, freshwater streams, coral reefs, and the legal frameworks that determine who can use them and how. This page examines the DLNR's structure, authority, operational mechanics, and the genuine tensions built into managing finite natural systems on a chain of islands in the middle of the Pacific Ocean.

Definition and scope

The Hawaii Department of Land and Natural Resources is a cabinet-level executive agency operating under Hawaii Revised Statutes (HRS) Chapter 171, which governs public land management. The DLNR administers approximately 1.3 million acres of state land — including conservation district lands, state parks, coastal zone areas, forests, and submerged lands extending to the 3-nautical-mile state boundary (DLNR, State of Hawaii). That number alone is worth pausing on: roughly 32 percent of Hawaii's total land area falls under DLNR jurisdiction in some form.

The department's mandate spans five broad categories: land administration, water resources management, conservation and coastal management, forestry and wildlife, and historic preservation. Each category carries its own regulatory apparatus, its own staff division, and its own set of conflicts.

The Board of Land and Natural Resources (BLNR) — a seven-member body appointed by the governor and confirmed by the state Senate — sits at the top of this structure. The BLNR holds authority to approve or deny land use transactions, permits, and conservation district use applications. The board is chaired by the DLNR's director, a dual role that consolidates administrative and quasi-judicial functions in a single appointed position.

For a broader view of how DLNR fits within Hawaii's executive branch architecture, the Hawaii State Government Structure page provides context on the full cabinet system and how agencies interact with the governor's office and legislature.

Scope and coverage limitations: DLNR's jurisdiction covers state-owned and state-administered lands. It does not govern privately held land (except where conservation district overlays apply), federally owned lands such as national parks and military installations, or county-administered properties. Federal lands — including Hawaii Volcanoes National Park and the Pearl Harbor National Memorial — fall under separate federal authority and are not covered here. County zoning decisions on private land are similarly outside DLNR's direct authority, though DLNR permits interact with county land use approvals. The Hawaii land use and zoning page addresses the county-level planning layer in detail.

Core mechanics or structure

The DLNR operates through nine functionally distinct divisions, each carrying its own enabling statutes and permit structures:

1. Division of State Parks — manages 50 state parks across the island chain
2. Division of Forestry and Wildlife (DOFAW) — administers 132 forest reserves and wildlife management areas
3. Division of Aquatic Resources (DAR) — regulates freshwater and marine fisheries, aquaculture, and reef management
4. Division of Boating and Ocean Recreation (DOBOR) — manages harbors, boat ramps, and ocean permits
5. Division of Conservation and Resources Enforcement (DOCARE) — the department's law enforcement arm, with statewide and ocean jurisdiction
6. Commission on Water Resource Management (CWRM) — operates semi-independently under HRS Chapter 174C to administer the state water code
7. Land Division — processes leases, licenses, easements, and land sales for state-owned parcels
8. State Historic Preservation Division (SHPD) — administers Section 6E of the HRS and coordinates with federal Section 106 review processes
9. Engineering Division — oversees dam safety under HRS Chapter 179, including the inspection of Hawaii's 130+ regulated dams

The Commission on Water Resource Management deserves particular attention. Established by the Water Resources Trust Act of 1987 (HRS Chapter 174C), CWRM designates water management areas, issues water use permits, and sets minimum instream flow standards. Its decisions have generated some of the most consequential water rights litigation in Hawaii history, including disputes over Maui stream diversions that reached the Hawaii Supreme Court.

Causal relationships or drivers

Three structural forces shape how DLNR operates, and none of them are simple.

Geographic compression. Hawaii has roughly 6,400 miles of coastline across all islands — a figure that reflects how much of the state is edge, boundary, interface. A small island with limited interior creates intense competition for coastal and near-shore resources. Every stream mouth, reef flat, and harbor entrance sits within multiple overlapping jurisdictional claims.

The public land trust. Under the Hawaii Admission Act of 1959, the federal government conveyed approximately 1.4 million acres of former federal land to the new state. The state constitution designates the revenue from these ceded lands as a public trust, with Native Hawaiian beneficiaries as one of five named purposes. This trust relationship directly shapes how DLNR must account for land transactions — a lease or sale of ceded land is not a routine commercial decision. The Hawaii Office of Hawaiian Affairs page examines the Native Hawaiian trust framework in depth.

Climate-driven resource stress. Coral bleaching events, invasive species encroachment into forest reserves, and reduced rainfall in leeward watersheds create management demands that outpace DLNR's staffing and budget capacity. Hawaii's Division of Forestry and Wildlife, for example, manages 132 forest reserves with a workforce that environmental advocates have described as chronically understaffed relative to the acreage under management.

Classification boundaries

DLNR's land management authority operates within Hawaii's four-category land use classification system, established by the State Land Use Law (HRS Chapter 205) and administered by the State Land Use Commission — a separate agency:

The Conservation District is where DLNR's authority is most concentrated. Any land use within a Conservation District — from a hiking trail to a telescope — requires a Conservation District Use Permit (CDUP) approved by the BLNR. The four conservation subzones (Protective, Limited, Resource, and General) determine what uses are permitted by right, allowed conditionally, or prohibited entirely under Hawaii Administrative Rules Title 13, Chapter 5 (HAR §13-5).

Water management has its own classification layer. CWRM designates specific geographic areas as "Water Management Areas" under HRS Chapter 174C when surface or ground water resources are determined to require regulation due to threatened sustainability. Designated areas require water use permits; non-designated areas are largely self-regulated by users.

Tradeoffs and tensions

The DLNR's portfolio of responsibilities contains contradictions that are not accidents — they reflect genuine competing values that Hawaii has not fully resolved.

Access versus protection. State parks are public resources held in trust for residents and visitors. The same reef that draws 10 million annual visitors to Hawaii (Hawaii Tourism Authority data) is damaged by those visitors' sunscreen chemicals, anchors, and foot traffic. DLNR's Division of Aquatic Resources manages the biological system while DOBOR manages the recreational access — and the two divisions' mandates can point in different directions.

Customary Hawaiian rights versus permit structures. HRS Section 1-1 preserves certain native Hawaiian customary and traditional rights. The extent to which DLNR permit requirements can be applied to practitioners exercising these rights — gathering, fishing, access to ahupuaa lands — has been litigated in Hawaii courts without producing a clean boundary. The Hawaii Native Hawaiian Sovereignty page examines the broader legal landscape.

Economic development versus conservation. The Thirty Meter Telescope (TMT) dispute on Mauna Kea's summit made global news precisely because it exposed how a Conservation District Use Permit sits at the center of genuinely incommensurable values: scientific access, sacred landscape, and the procedural legitimacy of a board making decisions about a mountain that means different things to different communities.

Water as a commons. Instream flow standards require CWRM to determine how much water must remain in a stream for ecological function versus how much can be diverted for agricultural or municipal use. Every instream flow standard is simultaneously an ecological determination and an economic one.

Common misconceptions

"DLNR manages all public land in Hawaii." Federal land — including 1.25 million acres administered by the U.S. Department of Defense across Oahu, Maui, and the Big Island — is outside DLNR jurisdiction entirely. So is land held by the U.S. National Park Service, the U.S. Fish and Wildlife Service, and the U.S. Forest Service's small presence in Hawaii. The Hawaii Military Presence page details the federal footprint.

"The BLNR's conservation district decisions are discretionary." The BLNR must follow Hawaii Administrative Rules Title 13, Chapter 5 when evaluating Conservation District Use Permits. Applications are evaluated against codified criteria. The board has judgment in applying those criteria but is not free to approve or deny on policy preference alone — decisions can be and regularly are challenged in court under the Hawaii Administrative Procedure Act (HRS Chapter 91).

"Water in Hawaii is owned by the state." Under HRS Chapter 174C, the state water code declares all water resources a public trust. No individual or entity owns water in Hawaii in the property-law sense. Rights to use water are allocated through permits, licenses, and existing uses — but ownership remains a concept that Hawaii water law deliberately excludes.

"DOCARE officers only enforce ocean rules." The Division of Conservation and Resources Enforcement has statewide law enforcement jurisdiction covering all DLNR-administered lands, including forest reserves, state parks, and hunting areas. DOCARE officers are sworn peace officers with arrest authority under HRS Chapter 190.

Checklist or steps (non-advisory)

Conservation District Use Permit (CDUP) application sequence under HAR Title 13, Chapter 5:

• Applicant identifies the Conservation District subzone classification of the parcel (Protective, Limited, Resource, or General) using DLNR's OCCL maps
• Applicant determines whether the proposed use is a "permitted use" by right, requires a CDUP, or is prohibited in that subzone
• Pre-application consultation with the Office of Conservation and Coastal Lands (OCCL) is completed
• Application package submitted to OCCL: completed DLNR Form 19, environmental assessment or statement (if required under HRS Chapter 343), site plans, and applicable fees
• OCCL reviews for completeness; incomplete applications are returned with deficiency notice
• Public notice period opens; adjacent landowners and public agencies receive notice
• BLNR schedules contested case hearing if objections are filed under HRS Chapter 91
• BLNR votes on the application at a publicly noticed board meeting; approval, conditional approval, or denial is recorded in board minutes
• Approved permits include conditions; permittee must comply with all conditions and report on construction commencement
• DOCARE enforcement applies to any activity inconsistent with permit conditions
