The owners of Turtle Bay Resort are proceeding with an expansion plan for the North Shore property that represents a scaled-back version of a previous owner’s plan.

Turtle Bay Resort LLC, a group of investment firms that owns the 880-acre property between Kahuku and Sunset Beach, proposes to add 1,375 more hotel and condominium units to the site.

The proposed density is about 60 percent less than a plan with 3,500 units and five hotels pushed by former property owner Oaktree Capital Management LLC, and 40 percent less than a draft plan with 2,345 units floated by Turtle Bay Resort LLC in March.

Other elements of the plan include five parks — four along the shoreline — spread over 73 acres, 160 units of affordable housing representing almost triple what’s required, a second resort entrance, a relocated equestrian center and reduction of one of Turtle Bay’s two 18-hole golf courses to nine holes.

The new plan is sketched out in a draft supplemental environmental impact statement preparation notice to be filed with the city Tuesday.
