The Center for Biological Diversity and Sierra Club have filed a lawsuit challenging a decision by the Napa County Board of Supervisors to approve a vineyard conversion project between the city of Napa and Lake Berryessa.

The board in December approved the Walt Ranch project, which would open up 209 acres of new vineyards. Craig and Kathryn Hall, owners of the Hall and Walt wine labels, are backers of the project.

The lawsuit, filed in Napa County Superior Court, alleges the project violates the California Environmental Quality Act and destroys habitats for threatened species.
