About 150 opponents of a plan to expand Turtle Bay Resort on Oahu’s North Shore demonstrated at Honolulu Hale Wednesday in an effort to raise public awareness and urge the City Council to reconsider decades-old approvals for the estimated $1.2 billion project.

The rally was dominated by members of Unite Here Local 5, the union that is upset about what it calls substandard wages at Turtle Bay. The union also contends that the expansion plan allowing time-share and condominium-hotel units won’t produce as many jobs as traditional hotels.

"The current development plan does not guarantee any good jobs," the union said in a Wednesday letter to Replay Resorts, Turtle Bay’s development consultant.

Also supporting and helping organize the rally were members of Defend Oahu Coalition, an environmental group chiefly opposed to the effects of traffic and building on unspoiled Kawela Bay and Kahuku Point bracketing Turtle Bay.

"We’re here to let the community know that the fight against Turtle Bay is not over," said Kent Fonoimoana, the group’s co-chairman.

Turtle Bay Resort LLC, a group of investment companies that owns the 880-acre property, proposes adding 625 hotel units and 750 residential units at the site containing the existing 443-room hotel and two golf courses.

The 1,375 units are largely concentrated along the mostly undeveloped coast, but represent reductions from a proposal for 2,345 units floated by the company early last year and one with 3,500 units pushed by the former property owner, Oaktree Capital Management LLC, in 2005.

Drew Stotesbury, resort operations and development CEO for Replay Resorts, said in a statement that the timing of the rally was unfortunate, especially because the company is producing a supplemental environmental impact statement that will assess project effects and mitigation measures.

A draft of the report is expected to be published later this summer. The report was required under an April 2010 Hawaii Supreme Court decision that found a 1985 EIS was outdated. Environmental groups Keep the North Shore Country and the Sierra Club Hawaii Chapter sued Oaktree and the city in 2006 over the issue, and prevailed after losing in two lower courts.

Some opponents deem any development outside the resort’s existing developed area to be unacceptable.

Cade Watanabe, Local 5 spokesman, said union representatives went to 2,200 homes between Waialua and Hauula in February and obtained signatures from 700 registered voters opposing the expansion. He said the petition now has more than 1,000 names, which will be presented to the Council.

Watanabe said Council members have the power to review past permits, some dating back more than 20 years, that allow the expansion.

"They have the ability to pull it back," he said.

Replay Resorts maintains that if the city determines supplemental EIS requirements have been fulfilled, then it may move ahead with the project because land use, zoning and other discretionary approvals were previously granted.
