Apple's proposed "ring" campus in the South Bay would cause traffic havoc and some air pollution, according to reports.
The company is seeking to construct 3.4 million square feet of office space in a "massive ring-shaped campus," according to Silicon Valley Community Newspapers.
The campus -- bounded by Interstate 280, North Wolfe Road, North Tantau Avenue and Homestead Road in Cupertino -- would cause "significant and unavoidable" traffic impacts in the area, according to an environmental impact report.
Apple's proposed 176-acre campus might cause less traffic havoc as long as additional highway lanes or turn lanes are built, the newspaper reported.
If not, "excessive queuing" at off-ramps and heavy traffic on "10 freeway segments" is likely, according to the report.
The environmental impact review is a draft document; a final version is due later this year, the newspaper reported.
