Hanalei Bay resort expansion draws backlash over seabird, community concerns

A plan to add six residential units, an event pavilion and a parking garage at 1 Hotel Hanalei Bay has reopened a familiar North Shore fight over how much more luxury development Princeville can absorb. The project lands at 5520 Ka Haku Road, where residents and conservation groups say another layer of activity could worsen seabird losses, traffic pressure and emergency access problems already familiar to Hanalei.

1 Hotel Hanalei Bay is the former St. Regis Princeville Resort, a 252-room property that reopened in February 2023 after a roughly $300 million overhaul. That investment, described as approaching $2.1 million per room, positioned the resort as one of Kauai’s highest-profile luxury properties. Now its owners are asking the county to amend older SMA, zoning and use permits to allow new construction on parcels at the terminus of Ka Haku Road, with planning documents saying the parcels involved total 23,139 acres.

The opposition is centered on the North Shore’s carrying capacity and on wildlife impacts that advocates say are already too high. Community groups that won intervention rights in the review argue the expansion would add more lights, more human activity and more infrastructure in an area where native seabirds are already vulnerable. Earthjustice has said existing 1 Hotel Hanalei Bay operations are already tied to more than 25% of all documented seabird take on Kauai, a level far above the authorized take quota.

The project has also drawn scrutiny from state wildlife officials. The Department of Land and Natural Resources’ Division of Forestry and Wildlife asked the Endangered Species Recovery Committee to review 1 Hotel Hanalei Bay’s 2025 Kauai Seabird Habitat Conservation Plan annual report, underscoring that the resort is already under active state wildlife oversight. The hotel is one participant in that conservation plan, alongside the County of Kauai and Royal Sonesta Kauai Resort.

The county process still gives residents a lever, at least for now. The Kauai Planning Commission granted intervention in the review, which has temporarily slowed the expansion decision. Any final county approval will come through the permit amendments now before the commission, while the state’s seabird review continues to shape how much pressure the resort can add.

That scrutiny matters on a North Shore that has already shown how fragile access can be. In March 2021, a landslide blocked Kūhiō Highway near Hanalei and left the community dealing with road closures and emergency access problems, a reminder that even modest new development can have consequences when the corridor is strained.
