Maui County is testing a new way to connect land-use decisions with the physical realities of a changing shoreline. On August 27, the Maui County Council’s Housing and Land Use Committee voted 5–4 to use sea-level-rise exposure as a key factor when deciding which apartment-zoned vacation-rental properties may be considered for hotel-district rezoning.
The decision is not an SMA permit rule by itself, but it shows how hazard mapping is increasingly shaping coastal development in Hawaii. Property owners planning renovations, rebuilding, additions, or changes in use should expect sea-level rise, erosion, flooding, public access, and long-term safety to receive close attention alongside traditional zoning and permit questions.
What the Maui Committee Approved
According to Maui Now, the committee adopted a threshold based on the state’s Sea Level Rise Exposure Area, commonly called the SLR-XA. This mapping tool combines three coastal hazards: passive flooding, annual high-wave flooding, and coastal erosion. It models several possible levels of sea-level rise, including a 3.2-foot scenario used in important Maui land-use decisions.
Under the committee’s adopted criteria, a property could qualify for consideration if at least 51% of it falls within the 3.2-foot SLR-XA, if it is subject to shoreline regulations adopted by the Maui Planning Commission, or if it lies within a special flood hazard area. Properties originally intended as affordable workforce housing would be excluded.
Supporters sought a consistent way to evaluate exposed properties. Opponents and community advocates warned that changing a property’s zoning or occupant type does not reduce erosion, extend a building’s useful life, or protect the beach. Committee members also discussed possible future conditions such as structural assessments, managed-retreat plans, limits on additional shoreline armoring, hazard disclosures, financial reserves, and public shoreline access. Those ideas were not all settled, and further committee discussion is scheduled for September 9.

Why This Matters for SMA Permit Planning
Maui’s debate highlights a broader lesson: coastal maps are no longer just background information. They can influence whether a project is feasible, what studies may be needed, how agencies evaluate cumulative impacts, and what long-term obligations could follow an approval.
An SMA application must demonstrate consistency with Hawaii Revised Statutes Chapter 205A and address issues such as environmental effects, cultural and historic resources, drainage, ocean views, shoreline access, and the cumulative effects of development. When a site overlaps erosion or flood hazards, reviewers may ask harder questions about safety, infrastructure, wastewater, emergency access, and the project’s expected life.
Practical Steps for Coastal Owners and Builders
Before committing to a design or construction schedule:
- Confirm every regulatory layer. Check SMA boundaries, shoreline setbacks, flood zones, the SLR-XA, zoning, and community-plan designations.
- Document current site conditions. Photograph drainage paths, vegetation lines, erosion, seawalls, utilities, public-access routes, and nearby structures.
- Plan beyond the building footprint. Consider sewer and water lines, fire systems, parking, evacuation, and other shared infrastructure that may be affected even if only part of a property is exposed.
- Build an adaptation story. Explain how the design responds to erosion, flooding, wave action, and future maintenance without shifting harm to neighboring property or the public beach.
- Engage agencies and neighbors early. Coastal proposals often draw questions about access, housing, cultural resources, and public cost. Early conversations can improve the application and reduce surprises.
- Use qualified professionals where required. Structural, geotechnical, wastewater, surveying, environmental, or architectural work may require licensed specialists.
How Shoreline Consulting Hawai‘i Can Help
Shoreline Consulting Hawai‘i helps homeowners, businesses, and developers organize the complex work behind SMA approvals. The team prepares site plans, environmental narratives, maps, charts, wastewater information, and other application materials; coordinates with county and state agencies; tracks policy changes; and works with trusted licensed professionals when specialized design or technical analysis is needed.
Minor SMA permits for projects under $500,000 commonly take two to six months, while major permits can take more than nine months. Commercial projects may also require an Environmental Assessment exceeding 150 pages. Starting with a clear hazard and permitting strategy can prevent redesigns and avoidable delays.
Maui’s sea-level-rise debate is still developing, but its direction is clear: future coastal decisions will increasingly connect land use with measurable shoreline risk. Proactive planning can protect private investment while respecting public access, community needs, and Hawaii’s beaches.
