Supplement to the Draft EIR (April 2011)
Supplement to the Draft EIR Appendices (April 2011)

In November 2008, a Draft Environmental Impact Report (Draft EIR) for the proposed Circle S Ranch Erosion Control Plan Project was prepared pursuant to the California Environmental Quality Act. The Napa County Conservation, Development and Planning Department is the Lead Agency for the project. The 1,593-acre Circle S Ranch property is located off Atlas Peak Road in south-central Napa County, California. The purpose of the project is to develop approximately 337 acres of new vineyard on slopes greater than five percent. In addition, approximately 41 acres of vineyard would be developed on slopes less than five percent. A total of 459 gross acres of vineyard and related facilities would be developed, including 378 net acres of vineyard. The project includes vegetation removal and earthmoving and grading activities associated with soil cultivation, installation and maintenance of drainage and erosion control features, and vineyard planting, and ongoing vineyard operations.

The Draft EIR was circulated through the Governor’s Office of Planning and Research, State Clearinghouse for a 45-day public review period. Subsequent to the preparation of the Draft EIR, additional studies were completed to address concerns in the areas of biological resources, groundwater use, transportation and traffic, and greenhouse gas emissions. These studies revealed additional information not available at the time of circulation of the Draft EIR. As a result, it was determined that further analysis would be required to analyze the extent of potential impacts as a result of the project. Based on these determinations, this Supplement to the Draft EIR was prepared and circulated.
