WAILUKU, Hawai'i — A Maui developer plans to conduct a new environmental study for a 1,400-unit housing project in the resort area of Wailea.

Honuaula Properties is planning improvements to Pi'ilani Highway, county roads, and a wastewater treatment plant that require an environmental impact statement.

Opponents have said the original environmental impact statement from the 1980s needs updating.

The Maui County Council has already voted 5-4 to approve zoning for the project.

But five Kihei residents have sued, alleging the council violated open meetings laws in its hearings on the development.

Second Circuit Judge Joseph Cardoza has stopped the county from advancing the project until he rules on the suit.
